Abstract:

Swamp Based Village Tourism in Central Hambuku Village is a recreation area that presents attractions in the form of customs and daily life of the people of Central Hambuku Village in the past and is a place of education for swamps as the largest natural potential in the Village of Central Hambuku. This tour aims to become a swampy tourist attraction that can develop the potential of the village to improve the economy of the Central Hambuku Village community. The development of village potential as a tourist attraction requires an analysis of the potential that can be exploited, through analysis-synthesis methods and the concept of memory is expected to explore the potential of existing villages to create a place for recreation and education of swamps as well as to give the impression and experience of life in the village.

Abstract:

The data of carbon stock of central African swamps forests are very few. This study carried out an assessment of the carbon stock of living biomass and coarse woody debris of three biotopes (flooded forest, seasonal flooded forest, and terra firm forest) of Likouala swamp forest (North of Congo). The average of the carbon stock are 190.72±98.7 tC/ha, 39.69±21.24 tC/ha, and 9.45±6.6 tC/ha respectively for above ground, billow ground, and coarse woody debris. The carbon stock of our swamp forest tends to increase generally from the flooded forest to the terra firm forest. In addition, the average of the coarse woody debris carbon stock increases with the increasing of the above ground carbon stock.

Abstract:

AbstractThe understanding of how basin margin sediment wedge builds out causes shelf-edge migration with time is approached based on shelf-edge trajectory pattern analysis using a high-resolution mega-merge seismic data from the eastern Niger Delta, Nigeria. The study focuses on a seismic dip transect traversing the Greater Ughelli, Central Swamp, Coastal Swamp and the Shallow Offshore Depobelts of the Niger Delta. On the regional dip transects, shelf-edge sediments occur as clinoform-bearing wedges at and immediately updip of the shelf-slope break. The shelf edge is deeply buried (> 2–4 s, twt), around the Greater Ughelli and Central Swamps. But with changing structural style, sudden change of ascending shelf edge around the Central Swamp was observed. The huge listric growth fault in the Coastal Swamp; around Bonny area, once again cut the shelf edge into half, rotated it along the listric fault and buried it distally. Several depositional packages show low to moderate ascending shelf-edge trajectory with progradational to aggradational clinoform growth that is characterized by thin sand sheets across most of the shelf and upper slope, though few are also characterized by progradational clinoform growth with thick sand on the shelf, upper-tolower slope and basin floor. The deposition is usually on the Outer Shelf Terrace (OST) which is regressive in a flat and rising trajectory style. This study has demonstrated that accommodation and sediment flux are the dominant controls on how the study basin’s sediment wedge built out, whereby limited accommodation promotes sediments with significant shelf-edge advance and descending trajectories, while increasing accommodation promotes ascending trajectories and increased deposition on the outer shelf. The greater sediments on the Outer Shelf Terrace and the shelf margin than on the slope gives more hydrocarbon prospectivity search around the outer shelf and shelf margin.

Abstract:

Local wisdom in utilizing swamp soil and water to improve the quality of gelam wood in Central Kalimantan becomes an interesting phenomenon. Improving the quality of wood can economize on the use of wood, which in turn preserves the forests in peat swamp lands. Gelam (Melaleuca sp.) woods that are mostly found in peat swamp forests can be used as piles/stakes in swamp soil, and they are durable for decades. The general objective of this study was to provide a scientific explanation of the effect of peat swamp soil and water on improving the quality of gelam wood either in barked and barkless conditions. This study was conducted by taking gelam trees that grew in Central Kalimantan. It was carried out for 18 months, and investigated the barked/barkless woods, media (swamp water, freshwater, peat swamp soil, and sandy soil) and 3 lengths of burying times. Wood properties analyzed were physical and mechanical properties. The standard of physical-mechanical property tests referred to British Standard 373. The results showed that the interaction between bark factor (A) and media (B) affected specific gravity. Barked wood produced the highest spesific gravity in swamp water medium. Water media (swamp and fresh water) improved the wood’s specific gravity more than soil media (swamp and sandy soil). The highest values of hardness, stress on Proportional Limit, and Modulus of Elasticity were in the medium of swamp soil. The improvement of the quality of gelam woods, which were either buried or used as stakes/piles, was allegedly resulted from the swamp water infiltrating into gelam woods that thereby increased the specific gravity.

Abstract:

The research area is located in the Muara Teweh, North Barito, Central Kalimantan. The cocking coal deposits are well known as they were produced from this area. Upper part of Tanjung Formation is target coal production. The study objectives are to analyze paleoenvironment and to determine the relative age of coal deposits based on palynological data. Preparing palinological analysis used standard procedure by hydrofluoric acid method.Palynomorphs data grouped into six types of ecology, and the sequence is as follows ; fresh water and lowland (41,75 %), brackish water swamp (30,10%), Peat and freshwater swamp (17,96%), marine element (7,77 %), back mangrove (1,46%) and upland element (0,97). Palmae pollen is very dominant, especially from freshwater and peat swamp that grow around coastal area i.e. Dicolcopollis, Proxapertites cursus, Proxapertites operculatus, Longapertites and Palmaepollenites kutchensis. Although marine fossil found, but the frequency less than one percent, that was the evidence of influence sea water to swamp area. The palynomorphs indicate the coal sedimented at upper delta plain. Fossil index of relative age consist of Proxapertites cursus, Proxapertites operculatus, Magnastriatites howardi Verrucatosporites usmensis, Retistephanocolpites , and Ixonantes type which refer to Late Eocene.

Abstract:

Abstract Miocene deposits in the eastern portion of the Greater Ughelli, Central Swamp and Coastal Swamp depobelts contain well-developed brackish-water trace fossil assemblages. Twelve ichnogenera have been identified, namely: Asterosoma, Bergaueria, Chondrites, Gyrolithes, Thalassinoides, Lockeia, Palaeophycus, ?Conichnus, Planolites, Siphonichnus, Skolithos and Diplocraterion. In addition, common non-descript, passively filled burrows and fugichnia (escape structures) have also been observed. The above-mentioned ichnogenera and associated non-descript structures can be arranged into six distinct and recurring ichnoassociations within the Greater Ughelli, Central Swamp and Coastal Swamp depobelts. Each ichnoassociation is comprised of a group of trace fossils which collectively reflect specific environmental conditions during deposition of these Miocene strata. All trace fossil assemblages illustrate deposition in nearshore, restricted settings. Ichnological and sedimentological criteria which may be utilized to recognise brackish-water deposits are discussed and illustrated in pictures of the cores studied.

Abstract:

Abstract The Indonesian government plans to turn Central Kalimantan province into a national food barn by planting rice paddies in several places, including in shallow peatlands. Tropical peatlands have limited potential to be used as agricultural land since the growing media in some cases, is not conducive to root development, saturated-water soil that poissons the plants. Aquatic invertebrates can be used as indicators to determine whether water quality in a field is safe for plants or not. The objective of this study is to evaluate the dynamics of benthic in different part of aquatic ecosystems on peat swamp forests. This study was conducted in Peat Techno Park (PTP) of the University of Palangka Raya, Central Kalimantan. Samples were collected from 9 stations with different forms of land use for agricultural activities, namely unplowed paddy fields, plowed fields, swamps, connecting ditches, beje, natural peat swamp forests, breeding ponds, and irrigation ponds. Data were collected over 6 months and coincided with the peak of dry and wet seasons. The abundance and species of aquatic invertebrates were then analyzed some related physic-chemical parameters, such as depth, water temperature, pH, and dissolved oxygen (DO). The results showed that the macrozoobenthos species found on this study was slightly rare. There was identified merely 3 genera, include in the two benthic groups, e.i. Annelida and insect. As to the insect, the dominant species was from the order of Diptera and family of Chironomidae, especially Chironomus. Spatially, stations 1 (unplowed rice fields), 2 (ploughed rice fields), 3 (peat swamp forest), 7 (cultivated ponds), and 9 (new beje) were particularly abundant. In this case, the conversion of peat swamp forests to rice fields and fish culture ponds will possibly promote greater diversity and abundance of macroinvertebrate communities.

Reinwardtia 19(1): 27‒54. ‒‒ Most peat swamp forest has been degraded. This has resulted in decline of its biodiversity. The objective of this study was to identify the composition, diversity, and plants used by local people in Bagantung swamp forest. The study was conducted on degraded peat swamp forest area in Bagantung, Mantangai Sub-District, Kapuas District, Central Kalimantan Province. The Shannon-Wiener (H’) and the Importance Value (IV) indices were used for analyzing the species diversity and the species importance across a number of forest plots. Useful tree species were identified by interviewing local villagers. There were 2,562 individual plants in 32 plots (each plot 20 m × 20 m). We identified 100 tree species and 16 non-tree species, from 74 genera, and 46 families. Myrtaceae, Sapotaceae, Ebenaceae, Dipterocarpaceae and Clusiaceae were the most dominant families. Large tree (H’=1.46) and small tree diversity was similar (H’=1.75). In both small and large tree size classes Calophyllum nodusum was the most dominant species. There were 16 tree species and two non-tree species used by local people for house and boat construction, furniture, handicrafts, medicine, and insect repellent.

Abstract:

Processes driving the assembly of swamp forest communities have been poorly explored. We analyzed natural regeneration and adult tree communities data of a swamp gallery forest in Central Brazil to discuss the role of ecological filters in shaping plant species turnover in a successional gradient. Species data of 120 plots were used to assess species turnover between natural regeneration and adult tree communities. Our analyses were based on 4995 individuals belonging to 72 species. Community patterns were discerned using ordination analyses. A clear floristic turnover among plant life stages was distinguished. Regeneration community of swamp forests was richer in species composition than the adult community. Tree species commonly found in nonflooded gallery forests were present in the regeneration plots but not in the adult community. Differences in the floristic composition of these two strata suggest that not all species in the seedling stage can stand permanent flooding conditions and only a few tolerant species survive to become adult trees. We propose that natural disturbances play an important role by altering limiting resources, allowing seeds of nonflooded forest species to germinate. This paper elucidates the turnover between plant life stages in swamp forests and suggests mechanisms that may shape these communities.

Abstract:

The avifauna of tropical peat swamp forests in East Kalimantan has not been well documented because of the smallest peat area compared to central Kalimantan. The surveys were conducted using various methods in the Muara Siran peat swamp forests and surrounding areas of Lake Siran (heath forest and riparian) in East Kalimantan, Indonesia. These findings were recorded on a list of 80 bird species as well as in numerous noteworthy records. Wetlands are an essential habitat for many threatened and near-threatened bird species. We also discovered Gallinula tenebrosa in Siran Lake, a species that has not been seen in over a century. However, it has a wide distribution globally, including in Australia and the United States. In the peat swamp forest, we recorded Cymbirrhinchus macrurus and Ichtyophaga humilis, rare and widely distributed. We also found Dicrurus hottentotus and Dicrurus remifer, some species of Ferruginous Babbler, Trichastoma bicolor, and the White-necked Babbler, Stachyris leucotis. The Hook-billed bulbul Setornis criniger and the Sooty capped Babbler Malacopteron affinae are found in riparian forests. There are six species of woodpecker. Dryocopus javensis, Great Slaty Woodpecker, Mulleripicus pulverulentus, Meyglyptes tukki, Picus puniceus, and Sasia abnormis. Cuckoo-shrike Coracina striata and Pitta sordia were also discovered. Wetlands (peat swamp forest, heath forest, and riparian areas) should be better protected due to their importance to many species, particularly from destruction and loss of habitat caused by forest fires.

Abstract:

Alpine swamps, among other wetlands, are of particular interest due to their relict nature, some peculiarities of their origin, functioning and dynamics, as well as due to their poor knowledge. The object of our study was a cascade swamp complex, consisting of three communicating baths and a lake, located at different heights in the Karasu river valley, in Upper Balkaria at an altitude of about 2 thousand meters above sea level. On the basis of our field descriptions, an analysis of the relief and vegetation of the mesotrophic and lowland bogs which constitute the complex was carried out. It was revealed that the basis of the plant communities of mesophytic segments is sphagnum and three types of sedge (marsh, urchin-hairy, and spout). There are communities of subalpine meadows and forests on the slopes around the wetland complex. It is assumed that the complex has some underground supply, in addition to rain and snow supply and runoff from the neighboring mountain massif.

Abstract:

Forests are natural resources that provide double benefits, direct and indirect benefits. The direct benefit of forest is as a source of various types of goods, such as woods, saps, barks, leaves, roots, fruits, and flowers that can be used directly by humans or become raw materials for various industries. The special-purpose forest of Tumbang Nusa is a secondary peat swamp forest. Peat swamp forest is a forest formation quite widespread in Indonesia. The term arises because swamp forest and peat forest are basically always adjacent and often do not have clear boundaries that are so-called peat swamp forests. The purpose of this study was to find out the structure and species composition (species dominance, species diversity, species richness and species evenness) of secondary peat swamp forest vegetation in special-purpose forest of Tumbang Nusa, Jabiren Raya Subdistrict, Central Kalimantan Province. The results of the study showed that the vegetation structure by diameter classes was dominated by the vegetation with small diameter (0-9 cm) and by height classes was dominated by the vegetation with low height-class (0-5 m). The diversity of vegetation in the study plots showed that there were 42 species of vegetation consisting of 24 families, and the most common species found were the family of Lauraceae (5 species), Dipterocarpaceae (4 species), Myristicaceae, Myrtaceae and Guttiferae (3 species), Podocarpaceae, Apocynaceae, Ebenaceae, Moraceae and Annonaceae (2 species), and a few other family (one species of each). The species diversity at seedling and sapling stages was moderate (H' ≥ 2 and < 3) while the diversity at pole and tree stages was low (H' < 2). The values of species richness index at seedling, sapling and pole stages were moderate (R = 3.5 - 5.0) while at the tree stage was relatively low (R > 3.5). The species evenness index at seedling and sapling stages was high (E > 0.6) while at the pole and tree stages moderate (E = 0.3 to 0.6).

Abstract:

Abstract Peat swamp forest is an important ecosystem in global climate change through its high carbon content and role as a carbon sink. In peat swamp forest, there is a near-closed cycle of nutrients including carbon. In order to better understand the rate of plant litter production and decomposition, a study was carried out in three secondary peat swamp forests in Central Kalimantan, Indonesia. Litterfall collection was undertaken using a litter trap with samples collected every month in the first year and every two months thereafter between June 2018 and June 2021. The rate of litter decomposition was assessed by measuring the reduction in dry weight of litter at 3, 6, 12 and 24 months. At each of three study sites, two sets of recently fallen litterfall were placed in 25cm x 25cm mesh bags on the peat soil surface to assess decomposition rates under aerobic conditions, and another two sets of litter were placed at a depth of 40 cm to assess decomposition rates under anaerobic conditions. Dry weight of fresh litterfall and decomposed litter samples was determined at 3, 6, 12 and 24 months, and total carbon content was analyzed using the loss of ignition method. The results showed that litterfall production in secondary peat swamp forests was about 9.52 ± 3.57 t ha−1 and it followed a seasonal pattern, with higher production in the dry season. The rate of litter decomposition was exponential and faster under aerobic conditions.

Abstract:

Abstract During a palynological analysis of four samples from the Bełchatów KRAM-P 218 collection of plant macroremains 95 fossil species of sporomorphs were identified. Among the non-pollen palynomorphs was the fossil species Desmidiaceaesporites cosmarioformis, previously not reported from fossil floras of Poland, most probably related to the zygospores of desmids. The pollen analysis indicates the presence of a freshwater body (probably an oxbow lake) and shows the dominant role of wetland, predominantly riparian vegetation, at the time of sedimentation. The riparian forests probably consisted of Carya, Pterocarya, Celtis, and Ulmus, accompanied by Alnus, Acer, Fraxinus, Juglans, Liquidambar, Vitis, Zelkova, and Salix. In mixed forests there probably were Fagus, Quercus, Carpinus, Eucommia, Corylus, Tilioideae, and conifers, as well as some thermophilous taxa (e.g. Castanea, Symplocos, Reevesia, Mastixiaceae, and plants producing pollen of the fossil species Tricolporopollenites pseudocingulum). Taxodium, Nyssa, and presumably Glyptostrobus and Alnus were components of swamp communities that might have overgrown the adjacent area with higher groundwater. Members of the families Ericaceae, Cyrillaceae, and Clethraceae, as well as Myrica and probably also Ilex, may have been components of swamp forests and bush swamps. Our analysis indicates that the climate was warm temperate and moderately wet. The palynoflora is most similar in composition to the spore-pollen spectra of the X climatic phase - the Nyssapollenites spore-pollen zone. Deposits bearing assemblages of the Nyssapollenites spore-pollen zone were deposited during the Sarmatian and early Pannonian. Our results are consistent with those from plant macroremains from the same collection.

Abstract:

Searching for mineral and energy resources in various regions of the Arctic basin has revealed the presence of huge reserves of oil, gas and other extractable resources. The coast of the Arctic Ocean, i.e. the European and the Asian north of Russia turns into the region of active economic development.Population migration flows into these regions will increase every year. People will move from the favorable climatic conditions to the extreme conditions of the Arctic. The harsh conditions of the Arctic are particularly heavy for the weather sensitive people with increased excitability of the central nervous system.In the extreme weather conditions, food is the most important means of organism protection. Therefore, a balanced diet is the most important means of human adaptation in the northern latitudes, with bee-farming products playing a huge role [4, 7].The Great Vasyugan swamp is the largest swamp with the area of 53,000 km2. It covers the Ob-and-Irtysh watershed, and stretches within 55040ʹ–58060ʹ N and 75030ʹ–83030ʹ E; its southern border stretches 573 km from the right bank of the Irtysh River to the left bank of the Ob River. From the southern border to the north, the swamp stretches for 320 km. In this area, there are huge reserves of peat, which make over 61% of the total stock in Russia. Among the swamp, there are islands, i.e. spaces not occupied by swamps and lakes, and covered with forest and grass [2].In the Tsarist times, the Vasyugan swamp was considered unsuitable for agriculture. Development of this region started after the October revolution. People grew gray cereals, fodder crops, potatoes, and vegetables. In this area, local horse breed named “narymka” was bred.After the Great Patriotic war, the Vasyugan Plain, or the Narym territory was deserted. Settlements were removed, and bushes and grass started growing in their place.Currently, the Great state program for studying the Narym territory has been started for using these areas to grow agricultural products to be supplied to the population of the Arctic Belt.

Abstract:

ABSTRACTVillage forest program is one of the breakthroughs of the Ministry of Forestry for community-based forest management. In order to manage the village forest, needing the data and information about the biomassa at the site. The research was aimed to estimate the above-ground carbon pool at the Buntoi Village Forest that located at the protection forest in the form of deep peat areas. This site is administratively located at the Pulang Pisau District, Central Kalimantan Province. Research result showed that above-ground carbon pool at the peat-swamp scrub of Buntoi Village Forest is predictively namely 16.510 ton, whereas above-ground carbon pool at peat-swamp secondary forest of Buntoi Village Forest is predictively namely 176.059 ton. These data are lower than Central Kalimantan REL standard, with the result the Buntoi Village Forest is suitable for carbon trade purpose at the future.Keywords: Buntoi, carbon pool, peat-swamp areas, village forest

Abstract:

AbstractThe third millennium BP crisis of the central African rainforest is not sufficiently understood. The low resolution of most pollen profiles and a large plateau of the calibration curve aggravate the exact dating of the event, and its causal climatic parameters are debated. We present a high-resolution pollen profile from the swamp site Nyabessan in the southern Cameroonian rainforest, covering the period 3100-2300 cal yr BP. Between 3100 and 2500 cal yr BP, the climate was favourable for a regional evergreen forest with Caesalpiniaceae and Lophira and a local Raphia swamp forest. Around 2500/2400 cal yr BP, a significant decrease of mature forest and swamp forest taxa and an increase of pioneers indicate that the rain forest was seriously disturbed and replaced by secondary formations. The dominance of Trema orientalis, a pioneer well adapted to seasonal desiccation, points to a much more accentuated seasonality after 2500 cal yr BP, which seems to be linked to a southwards shift of the ITCZ during the northern hemisphere winter months. We propose that the rain forest crisis between 2500 and 2200 cal BP created favourable conditions for farming and paved the way for a major expansion of Bantu speaking populations.

Abstract:

A vegetation survey at Oil Well Bog, southern Ontario, suggested that the central Picea mariana - Sphagnum (black spruce swamp) community represented the most mature point in the wetland succession. Pollen analysis of short sediment cores from beneath three major communities in the wetland (black spruce swamp, white pine swamp, and low shrub swamp) showed that the black spruce community only became established in the last 100 years. From around 2000 BP, the wetland was dominated by low shrubs with a tall shrub element. Upland forest composition around the wetland changed around 500 BP, with a decrease in percentages of Fagus and an increase in Pinaceae. At the same time trees colonized parts of the wetland. When the upland forest was cleared by European settlers (ca. AD 1830-1845), low shrub communities reestablished, suggesting that initially the wetland surface became wetter. Over time, the present-day mosaic of swamp types began to develop. The pollen analyses showed that the black spruce swamp is present as a result of changes in the wetland hydrology induced by human activity, and the fragmentary low shrub vegetation community (which contains locally rare plant species) represents a relic of the pre-European settlement wetland community.Key words: paleoecology, wetland development, hydroseral succession.

The use of medicine derived from natural ingredients had already begun since ancestors and passed down from generation to generation. However, the properties of those various plants were not clinically been proven. This study aims to find out phytochemical content of medicinal forest plants based on information from the local communities. The study was conducted in two ecosystem types namely wetland ecosystem in peat swamp of Sungai Rasau, Sebangau National Park, Central Kalimantan and dryland ecosystem in Meratus Mountain slope, Peramasan Bawah village, South Kalimantan. Vegetation data in the field was collected by making line transect. Phytochemical analyses qualitatively was done in the Faculty of Math and Natural Science laboratory of Lambung Mangkurat University, while specimen samples were taken from some species that commonly used by the local communities for medicinal purpose as 100 gr to 150 gr of gross weight of each plants. . Then the plant specimens were tested for their secondary metabolites comprised steroids/triterpenoids, quinone, tannin, flavonoids, saponins, and alkaloids tests in the laboratory. The research results showed that medicinal plants used by local communities were still available in their natural habitat In dryland ecosystem, there were 27 plant species discovered and 22 species found in peat swamp ecosystem that potentially use as herbal medicine. Phytochemical analyses showed that most of the plant samples were proved to have secondary metabolites in the form of steroid/triterpenoids, quinone, tannin, flavonoid, saponins and alkaloids. This condition showed that those plant species have potential as herbal medicine. However, those plant species still need further tests related to certain active ingredients potentially use as biopharmacy. Keywords: dryland, secondary metabolite, peat swamp, medicine

Abstract:

Above- and below-ground morphology of seedlings (up to 98 cm in height) were compared by allometric analyses in tropical heath forest and peat-swamp forest in Central Kalimantan. Thirteen abundant species were selected, including two species found in both forests. In above-ground morphology, heath forest seedlings invested more in leaf mass, while peat-swamp forest seedlings invested more in stem mass, stem height, crown area and leaf area. In below-ground morphology, heath forest seedlings invested more in root mass and depth, while peat-swamp forest seedlings invested more in lateral development of the root system. Both specific leaf area and area per leaf of heath forest seedlings were lower than those of peat-swamp forest seedlings. This differentiation in seedling morphology between forest types was evident as a plastic response in the two shared species. Heath forest seedlings on coarse-textured bleached sand with low water retention suffer occasional drought whereas peat-swamp forest seedlings on waterlogged peat rarely experience drought. We concluded that seasonal water limitation brought about the convergence in seedling morphology within heath forest because average understorey irradiances and soil nutrient concentration were assumed to be similarly low in both forests.

Abstract:

Mapping the above-ground carbon potential by using a non-destructive method has been a serious challenge for researchers in the effort to improve the performance of natural forest management in Indonesia, particularly in the ex-Mega Rice Project (MRP) area in Central Kalimantan Province. Nevertheless, the rapid and dynamic changes in secondary peat swamp forests are currently mapped effectively with the remote sensing technology using the Forest Canopy Density (FCD) model. FCD analysis as done by integrating vegetation index, soil index, temperature index and shadow index of Landsat 8 OLI images. The result was an FCD class map. In each class, parameter measurements were established for seedling, sapling, poles and tree stages. Above-ground carbon stock was calculated using three allometric equations. The results revealed that the values of carbon stock in ±16,147.26 ha dense secondary peat swamp forest, ±1,509.66 ha moderately dense scrub swamp forest, and ±632.07 ha sparse scrub swamp forest were, respectively, 79.28-122.96; 74.06-113.06; and 40.48-63.60 ton/ha. These results show that FCD application could be used to classify forest density effectively and in line with the variety of their attributes such us aboveground biomass and carbon stock potential.

Abstract:

Swamp Deer is an endemic species of the Indian subcontinent, mainly inhabiting tall grasslands in river floodplains. Populations of the northern subspecies (Rucervus duvaucelii duvaucelii), restricted to the Terai regions of northern India and western Nepal, have undergone dramatic declines over the past two─three decades. In this communication, we present results from systematic population counts conducted in Dudhwa Tiger Reserve between 2021─2022. These counts were conducted at 11 sites, each with two─three independent observers. The exercises covered summer, monsoon, post-monsoon, and winter seasons. We found the largest congregations of Swamp Deer in June during the summer and February in winter. In the monsoon months of July─September the Swamp Deer tend to use Sal woodlands along with farmlands adjoining the reserve edge. This is part of an ongoing research project on long-term monitoring and conservation of the threatened alluvial grasslands of the central Terai in Uttar Pradesh, India. Institutionalizing these monitoring practices for frontline forest staff is essential for understanding long-term population dynamics of the threatened Swamp Deer to develop conservation protocols for grasslands and their fauna.

Abstract:

AbstractThe association between the burrowing nematode Radopholus similis and giant swamp taro is studied in detail for the first time in corms collected from swampy taro patches in Yap, one of the states of the Federated States of Micronesia. The R. similis population from Yap displays similar variation in morphometrics and morphology as reported in the literature. The rot caused by the nematodes is wet with a loose mass of brown dead tissues and a deep brown necrotic centre housing nematodes inside. Usually, the infected tissues spread a disgusting odour typical of this disease. The dead tissues progress into shallow to deep cavities that advance towards the edible, central portion of the corm giving a perforated appearance on the outside of the otherwise smooth corm. The disease becomes more severe as the age of the plant increases. Nematode-infected plants seldom show any above-ground symptoms. The market quality of the corm is greatly reduced by the nematode damage. The widespread occurrence of the disease and the type of damage R. similis causes to the corms pose a serious threat to giant swamp taro production, food security and the continuation of traditional customs on those islands where R. similis occurs.

Abstract:

Abstract:Species of Miconia are considered keystone plant resources for frugivorous birds in Neotropical forests, but for other ecosystems little of their ecological role is known. The fruiting phenology and the composition of frugivores of four Miconia species in savanna and palm swamp from the Brazilian Neotropical savanna were studied in three sites from November 2005 to May 2011. The hypothesis tested was that plants from different habitats share their frugivores and consequently promote links between habitats. Through focal plant observations (30–50 h per species in each site), 668 visits by 47 species of birds were recorded and plants from different habitats shared most of the frugivores (49–97%). The fruiting of Miconia chamissois in the palm swamp during the period of fruit scarcity (dry season) was accompanied by an enhancement in the frugivore bird richness and abundance in this habitat, providing indirect evidence of resource tracking. Bird species which primarily dwell in savanna recorded consuming fruits in palm swamps during the resource-scarce season is taken as evidence of landscape supplementation. Miconia assemblage studied here seems to promote a link between two adjacent habitats in the Neotropical savanna from Central Brazil, a link which is likely to be common in this naturally patchy ecosystem.

Abstract:

Because Nepal has been virtually unexplored with respect to its trematode fauna, we sampled freshwater snails from grazing swamps, lakes, rivers, swamp forests, and temporary ponds in the Chitwan district of central Nepal between July and October 2008. Altogether we screened 1,448 individuals of nine freshwater snail species (Bellamya bengalensis, Gabbia orcula, Gyraulus euphraticus, Indoplanorbis exustus, Lymnaea luteola, Melanoides tuberculata, Pila globosa, Thiara granifera and Thiara lineata) for shedding cercariae. A total of 4.3% (N=62) infected snails were found, distributed among the snail species as follows (B. bengalensis - 1, G. orcula - 11, G. euphraticus - 8, I. exustus - 39, L. luteola - 2 and T. granifera - 1). Collectively, six morphologically distinguishable types of trematode cercariae were found: amphistomes, brevifurcate-apharyngeate (likely mammalian schistosomes), clinostome, gymnocephalus (likely fasciolid), longifurcate-pharyngeate and xiphidiocercaria. I. exustus had the highest prevalence of trematode infection, and harbored all the noted cercarial types except gymnocephalus cercariae. One double infection (xiphidiocercaria and longifurcate-pharyngeate cercaria) was found in this snail. Amphistome cercariae were common in G. euphraticus, G. orcula, and I. exustus. The highest prevalence of infection (38.3%) was recorded among snails collected from temporary ponds.DOI: http://dx.doi.org/10.3126/hjs.v7i9.2183 Himalayan Journal of Sciences Vol.7 Issue 9 2011 pp.9-14

AbstractThe swamp deerRucervus duvauceliiis the largest grassland-dwelling endemic cervid of India and Nepal. With a declining population trend across its range, this species is found in fragmented habitats of northern, north-eastern and central India and south-western Nepal. The northern swamp deer subspeciesRucervus duvaucelii duvauceliioccurs in small wetland patches across the states of Uttarakhand and Uttar Pradesh in India and has lost most of its habitat in the last century. Information about the distribution of the swamp deer in the upper Gangetic plains is limited, except in the Jhilmil Jheel Conservation Reserve in Uttarakhand and around the Bijnor barrage area of Hastinapur Wildlife Sanctuary in Uttar Pradesh. We surveyed the upper Gangetic plains between the Reserve and the Sanctuary, including some adjoining areas and three tributaries of the Ganges, to assess the status of these habitats, current swamp deer distribution and the threats faced by the species. We found several areas harbouring swamp deer within non-protected wetlands along the entire surveyed stretch of the upper Ganges and a previously unreported population in Uttar Pradesh. We documented major threats including habitat conversion, livestock grazing, poaching, conflict and other anthropogenic disturbances. We recommend community driven conservation and management ofRucervus duvaucelii duvauceliiin this fragmented landscape to ensure survival of this species and other threatened fauna of these wetlands and grasslands.

Abstract:

AbstractPollen analysis of two sediment records from a coastal swamp forest site in the Chilean semiarid region (31°50′S; 71°28′W) shows an alternation of dry and wet phases during the past ∼6100 cal yr B.P. The most prominent vegetation changes occur at ∼4200 cal yr B.P., with the expansion of the swamp forest taxa Luma chequen and Escallonia sp., followed by a regression of the forest beginning at ∼3200 cal yr B.P. and ending with its replacement by a xerophytic scrub, between ∼1800 and 1300 cal yr B.P. The swamp forest reexpanded after ∼1300 cal yr B.P. and persisted, with minor variation, until the present. We interpret the establishment of the swamp forest at the study site to be the result of a rising watertable in response to increased rainfalls from ∼4200 cal yr B.P. onward. Our results indicate that in north-central Chile the second half of the Holocene was climatically more variable than previously thought, suggesting significant changes in the position and/or intensity of the westerlies wind belt and possibly in the frequency of El Niño–Southern Oscillation events.

Abstract:

Rehabilitation of degraded peat-swamp forests, especially in Central Kalimantan Province, is becoming increasingly important in order to restore the ecological functions and maintain the biodiversity and carbon pool. The problem facing the rehabilitation effort is the limited knowledge about the techniques of rehabilitation on peat swamp lands using local species because inundation frequently occurs in this area during rainy season which greatly affects the growth of the plants. The purpose of this study was to analyze the level of resistance of plants to inundation on peat swamp lands in Pulang Pisau Regency, Central Kalimantan Province. The experiment was conducted in Taruna Jaya village, Jabiren subdistrict. Pulang Pisau Regency, using 14 different plant species endemic to peat swamp forests, with two factors, namely the level of immersion/inundation and plant species. In order to find out the plant resistance to inundation and the root growth, some variables were measured, such as the survival percentage of plants after tested in inundation and planted in the field, the assessment of the tree health using the criteria of Forest Health Monitoring (FHM), and the root-shoot ratio (RSR). The results showed that of the 14 species tested, Belangeran (Shorea balangera Korth) and Bintangur (Calophylum sp.) had good resistance to the condition of inundated soil, high adaptability in the field, and high value of RSR (root- shoot ratio). The plant species with high efficiency in absorbing nutrients and water were Shorea balangeran Korth, Calophyllum sp., Dyera polyphylla, and Alstonia pneumatophora. Those with the very high value of tree health were Alstonia pneumatophora, Calophyllum sp., D. pseudomalabarica, Dyera polyphylla, Shorea balangeran Korth, Trisraniopsis sp. and Stemonurus secondflorus.

Abstract:

AbstractThe late Quaternary vegetation of the semiarid coast of central Chile is inferred from the palynological analysis of profiles from Quereo (31°55′S) and Quintero (32°47′S). Prior to 11,400 yr B.P., wet conditions are suggested by the abundance of pollen indicators of swamp and aquatic taxa, such as Cyperaceae and Myriophyllum, and by the presence of traces of arboreal pollen. Since ca. 10,000 yr B.P., a trend toward increasingly drier conditions is implied by the almost complete absence of arboreal and aquatic taxa, and a general decrease in the diversity of the semiarid shrubland indicators. From 3000 yr B.P. onward, the pollen records show the reappearance of swamp and aquatic taxa, presumably associated with wetter conditions, which led to recolonization by forest taxa at 1720 yr B.P. in Quintero. The drier climate detected along the semiarid coast of central Chile during most of the Holocene extended inland to the Andean foot-hills, within the present mediterranean-type climate zone of Chile, and also affected the distribution of the winter-deciduous Nothofagus forests and the northern boundary of the temperate rain forests.

Abstract:

The palaeoenvironmental reconstruction of a site of archaeological interest in the Basin of Zacapu. in the north of the state of Michoacán, Mexico, was performed through pollen analysis. From the analysis of sediments of the central part of the swamp of Zacapu and the contact zone "Lomas"-swamp, it is possible to distinguish three climatic stages: from ca. 8100 to ca. 6700 BP, temperate-humid or sub humid weather; from ca. 6700 to ca. 5000 BP. temperate-semiarid weather; from ca. 5000 BP to the present time. temperate-subhumid weather. This study suggests that since 7000 BP, the ancient Lake of Zacapu has been a swamp-like water deposit. The climatic changes which can be inferred from this palynological analysis show more variations in the conditions of humidity than the thermal conditions. In the last 5000 BP, the weather in the area of Zacapu has been almost the same as it is in the present time: temperate subhumid.

Forest and land fire occurs almost every year in Indonesia. Its impact is very harmful for human and environment. Developing a program in fire management requires identification of forest and land fire characteristics and its causes. The aim of this research was to evaluate the characteristics and causes of forest and land fire in Kapuas District Central Kalimantan Province. Spatial analysis of hotspots with rainfall was used to determine temporal distribution of fire. Spatial distribution between hotspot and causative factors was determined to identify spatial characteristics of fires. Increasing number of hotspots occurs when monthly rainfall decreases. Most high fire activities are located in peatland, swamp shrubs, close to road, close to river and far away from villages. Fire causes from human activities mostly originated from swamp shrub burning and land clearing for farming. Hotspot density has various relationship with peat depth, land cover, accessibility, and human activities.

Peat land has an important role, function, and benefit for human life, biodiversity, and global climate. The peat swamp forest in Central Kalimantan was devastated to a very large extent, which addresses the restoration of peat swamp forests, has changed the characteristics of peat which contain physical, chemical, and biological characteristics. Peat recovery efforts carried out at the KHDTK Tumbang Nusa consist of natural succession and revegetation. The study aimed to analyze the chemical properties of peat soils in different types of post-fire forest protection and to assess the spatial variability of peat chemical properties in Forest Areas for Special Purposes (KHDTK) Tumbang Nusa, Desa Tumbang Nusa, Jabiren Raya District, Pulang Pisau Regency. The research plot consisted of forest restoration efforts, namely secondary forest, revegetation, and natural regeneration. Variable measured consisted of pH, total organic C, CEC, N, P, K, exchangeable K, Na, Ca, Mg, as well as ash content and water content. The results showed that secondary forest treatment was the best peat swamp forest restoration technique. Spatial variability sub-plots and sample points did not significantly affect the differences in chemical properties of the peat, but the differences in chemical properties of peat is the peat swamp forest was determined by restoration technique.

Abstract:

Cultivating of melon particularly in Central Kalimantan has been widely undertaken by farmers, however, the yields have not been able to meet the melon needs of Central Kalimantan's community. One of the breakthroughs in overcoming the problem is by growing melons on swamp floating beds, namely ambul technology. Ambul is growing media from decomposed floating aquatic plants, constructed with bamboo or wooden as a frame, that is let floating on waters. The ambul based on the consideration that the community lacks access to land for most of the year, which reduces opportunities for growing crops. The research design used was Split Plot Design with three kinds of aquatic plants as the main factor namely Eichornia crassipes, Salvinia molesta, Eleocharis palustris, and two melon varieties as subplot factors specifically Action 434 and Amanta. The results showed that the Amanta variety grown on S. molesta media produced the highest value of crop length on 1, 2, 3 weeks after planting (WAP). S. molesta was the best planting media for enhancing flowering by 11.43 days after planting (DAP) and weight of fruit (3.18 kg per plant. The variety of Amanta also had the highest value of root dry weight of 1.33 g per plant and fruit weight of 2.08 kg per plant.

Abstract:

Social wasps are widely distributed in Brazil, and their distribution is intimately linked to habitats and the vegetation structure. Veredas (Brazilian Palm swamps) occur in moist soils and are characterized by the almost monodominant presence of Buriti palms (Maurítia flexuosa). The insect fauna of these environments is poorly known, especially in Central Brazil. Some studies assessing the diversity of social wasps were carried out in the State of Mato Grosso, however, there are no studies performed in the palm swamps of this region. Thus, we aim in this study to investigate the composition of wasp species in six vereda environments throughout 24 months of sampling, from august 2017 to July 2019; The specimens were collected using a sweep net, in 200m transects that were subdivided into 10 3m2 parcels. To attract the wasps, we sprayed each parcel (using a backpack sprayer) with an insect attractant made from five spoons of granulated sugar and one spoon of salt dissolved in 5 liters of water. After spraying the plot, we waited 10 minutes before starting the collections and stayed another 10 minutes to sample in each plot, totaling 200 minutes of sampling per palm swamp. A total of 1062 social wasp specimens were collected, distributed in 10 genera and 36 species. The most abundant species were Polybia cf. ruficeps xantops (Richards, 1978), Angiopolybia pallens (Lepeletier, 1836), Polybia rejecta (Lepeletier, 1836), and Mischocyttarus sp. 2, which accounted for 57% of the total collected specimens in the 60 parcels. The estimated richness for the Vereda environments was 38,88 ± 0,627, approximately 41% of the 88 species of Polistinae wasps found in the Cerrado of eastern Mato Grosso.

Abstract:

Background and Aim: This study was conducted to estimate the prevalence and intensity and to identify the associated risk factors and impact of trematode infection in swamp buffaloes reared under different agro-climatic conditions in Java, Indonesia. Materials and Methods: A total of 580 fecal samples were collected from swamp buffaloes in five different agro-climatic areas in Banten and Central Java Provinces, Indonesia. The fecal samples were examined using the Danish Bilharziasis Laboratory Technique to determine the prevalence and intensity of trematode infection. The risk factors for infection were determined from an in-depth interview of owners/keepers, and the results were analyzed using Chi-square tests and multiple logistic regression. The infection was also correlated with swamp buffalo production parameters (body weight and body condition score [BCS]). Results: From all fecal samples, the overall prevalence of trematode infection was 64.83%, which comprised Fasciola spp. (16.03%; mean eggs per gram [EPG]±SD: 1.02±0.43) and Paramphistomatidae (62.93%; mean EPG±SD: 1.01±0.66). The main risk factor for trematode infection was feeding animals with rice straw (odds ratio [OR]: 40.124); the risk of trematode infection was 40.142 times higher in buffaloes that consumed rice straw. Other risk factors included the frequency of anthelmintic treatment (OR: 4.666), age (OR: 0.449), and drinking water source (OR: 0.358). Trematode infection did not significantly affect the body weight or BCS of swamp buffaloes. Conclusion: Although the prevalence of trematode infection was high in swamp buffaloes, the intensity of infection was low, and the infection did not affect the animals' physical parameters.
