Abstract (sommario):

Although mangroves have long graced the north Australian coastline, stable sea levels required for the formation of extensive mangrove swamp forests have occurred only intermittently over the late Quaternary. Most ancestral mangrove swamps are likely to have been formed below present sea level. The only well-preserved deposits that have been described, developed on the present continental surface as sea level reached its present position in the early Holocene. Gradual upstream shifting of mangrove communities from about 8400 BP is recorded in sediments from the wet tropics, followed by the establishment of extensive Rhizophora forests over the newly drowned estuaries. More extensive Rhizophora swamps developed in the monsoon tropics where an earlier transitional phase has not been preserved. These 'big swamps' infilled over the next 1500–4500 years as sediments accumulated above the now stable sea level. The present mangrove estate, though more restricted, is fairly stable, with maintenance of mangrove forests in protected prograding bays and in estuaries kept open by adequate river flow. In the short term, mangroves may be threatened by human influences, but any change in climate leading to a gradual change in sea level should again provide conditions for expansion of mangrove habitats across northern Australia.

Abstract (sommario):

Peat soil is a type of soil that is formed from the accumulation of plant debris which undergoes a decomposition process. This is why peat soil contains high organic matter and is acidic. Peat soils will affect the parameters of a surrounding aquatic ecosystem, such as the Rasau peat swamp ecosystem in the village of Rantau Panjang. Peat swamp water parameters are influenced by substances stored in the peat such as having a low pH, high heavy metal content, and having high TSS, TDS, BOD and COD values. The water parameter of peat swamp with mangrove vegetation is better than that of peat swamp that does not have mangrove vegetation. This can be seen if the peat swamp water parameters are laboratory tested. The physical parameters of water, namely temperature, TDS, DHL, color, and turbidity were lower in the Rasau peat swamp with mangrove vegetation compared to the non-vegetated ones. The chemical parameters of the Rasau peat swamp with high density mangrove vegetation such as higher pH, and lower BOD, COD, and iron (Fe) when compared to peat swamps without mangrove vegetation. However, the physical and chemical parameters of vegetated and non-vegetated peat swamps are still above the PPRI No. 82 of 2001.

Abstract (sommario):

Colombia has approximately 379,954 hectares of mangrove forests distributed along the Pacific Ocean and the Caribbean Sea coasts. Such forests are experiencing the highest annual rate of loss recorded in South America and, in the last three decades, approximately 40,000 hectares have been greatly affected by natural and, especially, human impacts. This study determined, by the use of Landsat multispectral satellite images, the evolution of three mangrove forests located in the Colombian Caribbean Sea: Malloquín, Totumo, and La Virgen swamps. Mangrove forest at Mallorquín Swamp recorded a loss of 15 ha in the period of 1985–2018, associated with alterations in forest hydrology, illegal logging, urban growth, and coastal erosion. Totumo Swamp lost 301 ha in the period 1985–2018 associated with changes in hydrological conditions, illegal logging, and increased agricultural and livestock uses. La Virgen Swamp presented a loss of 31 ha in the period of 2013–2018 that was linked to the construction of a roadway, alterations of hydrological conditions, illegal logging, and soil urbanization, mainly for tourist purposes. Although Colombian legislation has made efforts to protect mangrove ecosystems, human activities are the main cause of mangrove degradation, and thus it is mandatory for the local population to understand the value of the ecosystem services provided by mangroves.

Abstract (sommario):

Mangrove swamps are important habitat types providing vital ecological services, such as protection of coastlines from erosion and extreme weather conditions including hurricanes, recycling of nutrients and sequestration of carbon. Mangrove swamps support a wide range of biodiversity, improve water quality, provide fish for local communities. They are also used as a source of wood fuel, medication as well as for harvesting honey for the local population. Soil samples for laboratory analyses were collected from red (Rhizophora mangle), black (Avicennia germinans) and white (Laguncularia racemose) mangroves in Florida, USA to determine the biogeochemistry processes. Results of analyses indicated that the red mangrove soil is the most efficient for carbon sequestration. It had the lowest phenol oxidase activity (206.15 nmol dicq g-1 h-1), highest phenolic concentration (262.33 µg g-1) and lowest hydrolase enzyme activity (β-glucosidase) (3.04 nmol g-1 min-1) and, as a result, the highest concentration of soil organic matter (SOM) (57.9%). It is believed that the high soil water content (84.2%).) of the red mangrove, due to its proximity to the sea, is a key driver of these observations. The 'enzymic latch' mechanism appears to be prevalent in the red mangrove soil, in particular, allowing these ecosystems to be effective at carbon storage hence, could serve as an important natural tool in mitigating the effect of climate change. Preservation and conservation of mangrove swamps is vital in balancing the effect of global warming.

Abstract (sommario):

Mangrove ecosystems provide a wide range of market and non-market benefits to coastal communities in the developing world, yet they remain undervalued and overexploited in most regions where they are found. This paper analyzes the use and value of mangroves in Kosrae, Micronesia, where the population is largely dependent on the swamps for fuelwood and other ecosystem services, such as erosion control, storm protection, and nutrient flows to shoreline fisheries. The results show that mangroves on the island are worth between $666 thousand and $1 million per year (1996 prices) based on the net value of marketable products alone. In addition, household survey data suggest that the local people are willing to pay between $1 million and $1.26 million per year to protect and use mangrove swamps indefinitely. The results thus indicate that the population places some premium on the existence and indirect ecosystem services of mangroves, over and above the direct use values. Moreover, respondents generally favored—and were willing to pay more for—a tax system designed to manage and preserve the mangroves' direct and indirect services over a permit system focused only the allocation of direct use over time. Valuation analyses using revealed preference and contingent valuation methods lead to additional conclusions regarding the distribution of benefits, with poor households deriving more direct benefits from—but willing to pay less to protect—mangrove ecosystems.

Abstract (sommario):

Research on amphibian diversity in Rivers State, Nigeria, was conducted between 2015 and 2019. The survey covered seven Local Government Areas and three ecological zones (lowland forest, freshwater swamp and short mangrove). The surveyed areas were Ikwerre LGA (Isiokpo), Emohua (Rumuji and Ndele), Okrika (Fiberesima Polo, ATC sandfill, Greame Ama), Khana- Ogoni (Bori, Kaani 1), Ogba-Egbema-Ndoni (Omoku), Ahoada East (Ahoada main town, Ikata) and Obio-Akpor (Agbada, Rumuagholu, Rumuesara). The habitats included farmlands, fallow areas, swamps, streams and inundated areas, bush paths, human settlements and forested areas. Visual encounter and acoustic survey methods were used. Nineteen amphibian species were encountered including members of the Arthroleptidae, Bufonidae, Dicroglossidae, Ranidae, Hyperoliidae, Ptychadenidae and Pipidae. Freshwater swamps and short mangrove ecological zones (characterized by human settlements and farmlands) had the lowest diversity of two and five amphibian species, respectively. The highest diversity comprised of eighteen different amphibian species was recorded in forested habitats of the lowland forest/freshwater swamp ecological zone. 569 individuals were collected from lowland forest/freshwater swamp ecological zone; 215 from lowland forest; 60 from short mangrove; and 28 from freshwater swamp ecological zone. Shannon diversity was highest in the lowland/freshwater swamp ecological zone (H=2.12) and lowest in the freshwater swamp zone (H=0.52). It is concluded that a forested habitat comprised of the combination of lowland forest and freshwater swamp ecosystems hosts a greater diversity of amphibian species.

Abstract (sommario):

Mangrove wetlands are important ecosystems, yet human development coupled with climate change threatens mangroves and their large carbon stores. This study seeks to understand the soil carbon dynamics in hydrologically altered mangrove swamps by studying aboveground biomass estimates and belowground soil carbon concentrations in mangrove swamps with high, medium, and low levels of disturbance in Cataño, Jobos Bay, and Vieques, Puerto Rico. All three sites were affected by hurricane María in 2017, one year prior to the study. As a result of being hit by the Saffir-Simpson category 4 hurricane, the low-disturbance site had almost no living mangroves left during sampling. There was no correlation between level of hydrologic alteration and carbon storage, rather different patterns emerged for each of the three sites. At the highly disturbed location, belowground carbon mass averaged 0.048 ± 0.001 g-C cm−3 which increased with increased aboveground biomass. At the moderately disturbed location, belowground carbon mass averaged 0.047 ± 0.003 g-C cm−3 and corresponded to distance from open water. At the low-disturbed location, organic carbon was consistent between all sites and inorganic carbon concentrations controlled total carbon mass which averaged 0.048 ± 0.002 g-C cm−3. These results suggest that mangroves are adaptive and resilient and have the potential to retain their carbon storage capacities despite hydrologic alterations, but mass carbon storage within mangrove forests can be spatially variable in hydrologically altered conditions.

Abstract (sommario):

Mangrove plants are specialized timbered plants growing in the swamps of tidal coastal areas and stream deltas of tropical and subtropical parts of the world. They have been utilized for medicinal and traditional purposes by the coastal folks over the years. A large number of mangrove plants grows natural and exploited especially, for use in indigenous pharmaceutical houses. Several mangroves genus produce expensive drugs which have high export potential. The utilization of plants and plant products as medicines could be traced as far back as the commencement of human civilization. Mangrove plants have been used in folklore medicines and extracts from mangrove species have prove inhibitory activity against human, animal and plant pathogens. Traditionally, the mangroves have been exploited for firewood and charcoal. Exploit has been found for mangroves in the manufacture of dwellings, furniture, boats and fishing gear, tannins for dyeing and leather production. The mangroves afford food and wide variety of traditional products and artefacts for the mangrove dwellers. The present review deals with the pharmacological activity, medicinal, traditional and produce bioactive compounds of mangrove medicinal plants. Keywords: Mangroves, Medicinal, Pharmacological, Recourses, Traditional.

Abstract (sommario):

Madura island is known as a mixed deciduous forest area with dry seasons and limestone soil. The island has unique plant species compared to the mainland Java. However, most of the mangrove forest areas have been converted into ponds and housing. One of the remaining mangrove swamps is located at Telang Asri village, Kamal Subdistrict, Bangkalan Regency. Several species of mangroves have been reported here, along with other groups of plants from the Phyllanthaceae family, found numerously at the time of observation. In 1963, CA Backer and RC Bakhuizen van den Brink Jr. have already listed 16 species of Phyllanthaceae from Madura Island. Since then, the updated information on the Phyllanthaceae of Madura has not been available. Therefore, this study aimed to collect the members of Phyllanthaceae family in the mangrove swamp areas of Telang Asri village. The field study was carried out using the exploratory method, while specimen preparation was conducted in Herbarium Bandungense (FIPIA). In this study, seven species were collected from Telang Asri, namely Glochidion littorale Blume, G. zeylanicum (Gaertn.) A. Juss., Phyllanthus amarus Schumach. and Thonn., P. debilis Klein ex Willd., P. reticulatus Poir., P. urinaria L., and P. virgatus G. Forst.

Abstract (sommario):

Anthropogenic activities along coastal areas have contributed to the unwarranted discharge of toxic metals into mangrove swamps, posing risks to marine deposits and ecological environments. In this research, we studied the Isaka–Bundu tidal swamp area in the Niger Delta, which is an impacted mangrove creek located along the Bonny river, exposed to pollution pressures. The ecological risks (Er) of toxic metals in the sediments and water of the Isaka–Bundu tidal mangrove swamp followed a decreasing order (Cu > Zn > Cd > Cu > Pb > As), according to our results, while the potential ecological risk index (PERI) of the toxic metals in the sediments and water of the Isaka–Bundu tidal mangrove swamp can be said to have a very high ecological risk (PERI ≥ 600). The sediment pollution load index (PLI) was higher than 1 in all three analyzed stations, suggesting extremely toxic pollution. The enrichment evaluation shows that the studied stations have a moderate potential ecological risk of Cd, with the enrichment value for Pb showing low potential ecological risk. Our study shows that the Isaka–Bundu tidal mangrove swamp has a significant level of toxic metal pollution, which is evidence of the illegal activities performed in the Niger Delta.

Abstract (sommario):

Tropical and subtropical mangrove swamps, under normal conditions, can sequester large amounts of carbon in their soils but as coastal wetlands, they are prone to hurricane disturbances. This study adds to the understanding of carbon storage capabilities of mangrove wetlands and explores how these capacities might change within the scope of a changing storm climate. In September 2017, Naples Bay, FL, USA (28°5′ N, 81°47′ W) encountered a direct hit from hurricane Irma, a Saffir–Simpson category 3 storm. By comparing carbon storage, forest community structure, and aboveground productivity collected in 2013 and in 2019, we estimated the effects of hurricane Irma on mangrove functions. Aboveground biomass increased during the study period at a rate of approximately 0.72 kg m−2 yr−1, significantly less than the average found in undisturbed mangrove forests. Soil carbon storage decreased at all study sites. On average, 2.7 kg-C m−2 was lost in the top 20 cm between sample collections. Carbon loss in belowground pools could point to a feedback of mangrove swamps on climate change as they lose their ability to store carbon and increase net atmospheric carbon. Nevertheless, mangrove swamps remain resilient to tropical storms in the long term and can recover their carbon storage capacity in the years following a storm.

Abstract (sommario):

This paper investigated climate change-associated agricultural losses, food scarcity and adaptation strategies in the freshwater and mangrove swamps of Delta State in the Niger Delta region. A total of 1600 respondents were selected comprising 800 respondents equally selected from two local government areas per ecological zone. Structured questionnaire was used to collect data for this study. Findings show that a combination of loss of farm land and inputs and crop failure mainly accounts for agricultural losses due to climate change while flooding is primarily responsible for food losses due to climate change in both ecological zones. Purchase of food within and outside the community account for over 80% and 74% of the respondents main sources of food during climate change incidence in the freshwater and mangrove swamps respectively. Dietary management, change of occupation and livelihood diversification account for over 80% of the respondents coping strategies against climate change-induced food shortage in the freshwater swamps while dietary management, out migration and relief materials make up over 65% of the respondents adaptation strategies in the mangrove swamps. While the paper recommends ecological zone-specific prioritization in tackling climate change-induced agricultural losses and food shortage, there should be provision of nutrition education for households in both ecological zones.

Abstract (sommario):

Surface sediments from two mangrove swamps in Hong Kong were enriched to obtain PAH-degrading microbial consortia. The consortium from sediments enriched with phenanthrene (Phe) in Ma Wan, a mangrove swamp next to a boat anchorage, was effective in degrading PAH with 96.7% and 89.9% Phe degradation at 0 and 10 ppt salinities, respectively. The Phe-enriched microbial consortium could also use pyrene (Pyr) as the sole carbon source but the degradation was much less (around 15%). On the other hand, the Phe-enriched consortium from sediments in Yi O, a mangrove swamp recently polluted by an oil spill, completely removed Phe and Pyr at both 0 and 10 ppt salinities. This suggests that different consortia were selected in two sediments using the same PAH substrate. Not only sediments, PAH substrate used for enrichment also selected different consortia. The Pyr- and Fla-enriched Yi O consortia only achieved 10.5 and 4.5% Phe degradation, respectively and the corresponding pyrene degradation was 7 and 40%. Among the three PAH compounds, fluoranthene (Fla) was most difficult to degrade, and 21.1, 11.3, and 36.8% Fla were degraded by Phe-, Fla- and Pyr-enriched cultures, respectively.

Abstract (sommario):

AbstractThe phylum Labyrinthulomycota is composed of three distinct groups of fungus-like organisms: the labyrinthulids, the thraustochytrids and the aplanochytrids. They are present in marine and brackish waters as saprobes and/or parasites. In recent years, there was an increased interest in studying these organisms due to the ability that some have to produce large amounts of lipids, particularly polyunsaturated fatty acids. However, in spite of their importance and diversity, in Brazil only four species were reported in the 1970s. Due to their ecological and economic importance globally and the limited knowledge of them in the country, this study aimed to evaluate the diversity of the Labyrinthulomycota in mangrove swamps and coastal waters of São Paulo State, Brazil. The specimens were isolated from water and leaf samples using different methodologies, and purified in an agar medium prepared with half-strength sterile seawater, peptone, yeast extract and glucose. After purification, they were identified by means of morphology and phylogenetic analysis of the SSU rDNA region. A total of 193 specimens representing five genera were observed, 26 specimens were incorporated into the culture collections and 29 sequences of the SSU rDNA region were deposited in GenBank.Labyrinthulasp.,Aurantiochytriumsp.,Parietichytrium sarkarianumandThraustochytrium striatumare new records for Brazil, contributing to our knowledge of the diversity of fungus-like organisms in the country.

Abstract (sommario):

Myotis hasseltii (Temminck, 1840) variously known as the brown bat, Van Hasselt’s bat, Van Hasselt’s mouse-eared bat, or lesser large-footed myotis in the vernacular is a patchily distributed species; aside from Sri Lanka, within the Indian Subcontinent it is found only in West Bengal. The brown bat is thought to be uncommon and is a resident of land below the 1000m contour. It has been reported to roost alone or in small groups in bamboo clumps, cracks in tree bark, and in abandoned buildings. Mangrove swamps are another possible habitat for these bats. M. hasseltii likes living near water and flies low over streams, tanks (reservoirs), and mangrove swamps hunting for gnats, small flies, and mosquitoes. Extralimitally, an individual of this species was found with fish remains in its stomach.

Abstract (sommario):

ABSTRACTA representative sample of waterways in Liberia was surveyed for crocodiles, and all three species of African crocodiles were observed. Contrary to previous reports, only Nile crocodiles inhabit the Monrovia mangrove swamps and brackish-water mouths of rivers; there are no slendersnouted or dwarf crocodiles in these habitats. There is partitioning of habitats among the three species in Liberia: Nile crocodiles in mangrove swamps and river mouths (brackish water); slendersnouted crocodiles in rivers through rain forest (freshwater); and dwarf crocodiles in small streams through rain forest (freshwater), some entering the adjacent river. Dwarf crocodiles utilize burrows in the stream banks.Nowhere are crocodiles abundant, and there is an apparent absence of adults. Although 40% of Liberia is forested, deforestation is occurring rapidly by foreign timber companies and slash-and-burn agriculture practised by the largely rural population. Hunting with firearms, although illegal, is widespread, both for subsistence and commercially, without concern for depletion. Mangrove ecosystems near human population centres are being destroyed. The combination of the above factors has apparently depleted the crocodile populations in Liberia.

Abstract (sommario):

Mangroves perform a crucial role in maintaining the ecological integrity of the coastal ecosystem. They act as filters in the coastal zone, preventing the damaging effects of upland sediments on seagrass beds and coral reefs, minimise the effects of storm surges and act as carbon sinks that mitigate climate change. These essential services, however, are degraded through indiscriminate cutting, conversion of mangrove swamps to fishponds, reclamation projects and other coastal developments and pollution. Experts reveal that the Indo-Malay Philippine Archipelago has one of the highest rates of mangroves loss. From an estimated 500,000 hectares of mangrove cover in 1918, only 120,000 hectares of mangroves remain in the Philippines today. The country has had the legal and policy framework to protect and conserve mangroves. But weak implementation of laws, overlapping functions among agencies and, in general, poor management by the people and local governments have hindered the sustainable management of mangrove forests. Positive developments, however, are taking place with the promulgation of laws on climate change and executive orders which specifically include mangrove and protected areas under the National Greening Program (NGP) and addresses equity, food security and poverty issues by giving preference to NGP beneficiary communities as a priority in the Conditional Cash Transfer (CCT) Program. Moreover, participatory Planning and Multi-stakeholder Approaches are among the strategies contemplated by the Philippine National REDD + Strategy. The article examines the implementation and effects of the Philippine National REDD+ Strategy, the National Climate Change Action Plan which specifically integrates REDD+ and ecosystem valuation into decision-making, and the executive orders which support the mainstreaming of the National Greening Program.

Abstract (sommario):

This study aims at documenting the value chain derived from mangrove forests in selected sites in central Mozambique (Zambezi Delta, Nhangau and Chiveve River), through the identification of the services delivered by mangrove forests and assessment of stakeholder’s engagement within the value chain. Furthermore, this work evaluates the income pathways as well as the current and potential benefits of different stakeholders and the socio-economic sustainability of mangroves in the three regions. Zambezi Delta is one of largest mangrove swamps in Africa and Chiveve is located in Beira City, impacted by Cyclone Idai in 2019. The main benefits obtained by the communities both in the Zambezi Delta and Nhangau were derived from commercially important wood extraction and honey production for domestic use. Within the Zambezi Delta, profit for small mangrove poles accrued at the wholesale level (82.6%), while that for large poles accrued to harvesters (125.0%), after a small initial direct investment. At Nhangau, small poles fetched profits of 17%, medium poles 11.5%, and large poles 24%; for charcoal, the greatest portion of profits went to retailers at 50%. Men were mostly involved in mangrove wood harvesting for commercial purposes, while women collected firewood mainly for domestic use. At the Chiveve, the community benefited predominantly from non-extractable services such as flooding control, water purification, nursery grounds for fisheries and aesthetic beauty. It is suggested that Mozambique mangrove forests are valued at USD 2 400 per hectare per year. This monetary accounting can be used to inform decision making on mangrove management and to improve the performance of the value chain and the wellbeing of local communities.

Abstract (sommario):

Mexican wetlands are not included in Earth system models around the world, despite being an important carbon store in the wetland soils in the tropics. In this review, five different types of wetlands were observed (marshes, swamps, flooded grasslands, flooded palms and mangroves) in which their carbon pool/carbon sequestrations in Mexican zones were studied. In addition, it was shown that swamps (forested freshwater wetlands) sequestered more carbon in the soil (86.17 ± 35.9 Kg C m−2) than other types of wetlands (p = 0.011); however, these ecosystems are not taken into consideration by the Mexican laws on protection compared with mangroves (34.1 ± 5.2 Kg C m−2). The carbon pool detected for mangrove was statistically similar (p > 0.05) to data of carbon observed in marshes (34.1 ± 5.2 Kg C m−2) and flooded grassland (28.57 ± 1.04 Kg C m−2) ecosystems. The value of carbon in flooded palms (8.0 ± 4.2 Kg C m−2) was lower compared to the other wetland types, but no significant differences were found compared with flooded grasslands (p = 0.99). Thus, the carbon deposits detected in the different wetland types should be taken into account by policy makers and agents of change when making laws for environmental protection, as systematic data on carbon dynamics in tropical wetlands is needed in order to allow their incorporation into global carbon budgets.

Abstract (sommario):

In Kerala Basin the Tertiary sedimentary sequence is represented by Quilon and Warkalli formations. Palaeoassociations of upland, lowland, fresh-water, sandy beach and mangrove vegetations have been figured out. Composition of the palynological assemblages indicates the existence of tropical rain forests with a high degree of rainfall. Dinoflagellate cysts and pollen grains of Barringtonia, Rhizophora, Nypa and Calamus suggest deposition under brackish water mangrove swamps. The sandy beach conditions are indicated by Palmidites, Palmaepollenites and Quilonipollenites. Divergent views on the age of Quilon and Warkalli formations have been reconsidered on the basis of new palynological evidences.

Abstract (sommario):

A diversified palynofloral assemblage has been recovered from the Kherapara Formation (Oligocene) exposed along Tura-Dalu Road near Kherapara. West Garo Hills District. Meghalaya. India. The palynoflora is represented by 53 genera and 77 species of algal and fungal remains, pteridophytic spores and gymnospermous and angiospermous pollen. Of these, three species, viz. Garotriletes kheraparaensis, Striatriletes tetradites and Echistephanocolpites quadrangullaris have been proposed as new. Reworked Permian and Cretaceous palynofossils (10 genera and 11 species) have also been recorded. The assemblage is dominated by pteridophytic spores followed by angiospermous and gymnospermous pollen. Based on palynofossil distribution. the Kherapara Formation is divisible into two cenozones. viz., Polyadopollenites sahii Cenozone and Striatriletes spp. Cenozone which can be recognised by their characteristic and restricted palynotaxa. On the basis of affinity with the modem plant families represented in the assemblage and dominance of pteridophytic spores, a tropical-subtropical (warm-humid) climate has been suggested. The assemblage contains a mixture of ecological groups such as lowland. fresh water swamp and water edge, montane, mangrove and back-mangrove and sandy beach elements. The palynoflora indicates a coastal marine depositional environment of deposition having fresh water connections with swamps and ponding conditions nearby.

Abstract (sommario):

Based on stratigraphical, sedimentological and geomorphological methods, a preliminary stratigraphic division is proposed to the Praia do Sul coastal plain, a state Biological Reserve, located in "Ilha Grande", Rio de Janeiro. This reserve was created to preserve the natural ecosystems found therein (sandy coastal plain, mangrove, lagoon, rocky coast and hillside fo rest). The Praia do Sul sedimentation plain is essentially constituted by continental gravels and sands of Upper Pleistocene, marine sandy formations, fluvial-lagoonal sandy-clayer formations and present mangrove swamps and beachs. The paleogeographic evolution of this area can be followed through the sedimentary association that permits to establish the transgressive and regressive process that occured during the Quaternary period.

Abstract (sommario):

The Douglas Shire is a small coastal shire in the wet tropics of North Queensland, lying between Buchan Point in the south and Bloomfield in the north. It is dominated by steep rainforest-covered mountains with a narrow coastal strip, rising from sea level to 1370m in only 6km. Annual rainfall varies from 1000mm in the south to 3750mm in the north. It is a very well watered district with four main rivers and several good creeks, all of which are very fast-flowing. Before clearing began, two-thirds of the Shire was under heavy tropical rainforest, the other third was timbered grassland (eucalypt and wattle) with some melaleuca and mangrove swamps. There are also beaches, sand ridges, mangrove-lined rivers and creeks, and some salt pans.

Abstract (sommario):

Abstract. Mangrove forests are extremely productive ecosystems, are sources and sinks of organic carbon, and provide essential services both to the marine environment and people. We have studied the composition and species richness of modern benthic foraminiferal assemblages from mangrove swamps along the Mamanguape River in Paraíba, northern Brazil. Sampling points for foraminifera were selected to acquire information on the composition of foraminiferal assemblages from dense mangrove stands collected along a river transect. Almost 100 species of benthic foraminifera were identified within the shallow mangrove habitats. The large number of identified mangrove taxa is the highest recorded so far for true mangrove habitats. The high species richness rivals shallow-water assemblages recorded from nearby offshore and reef environments and indicates that a particularly large number of species is capable of growing and flourishing under multiple stressor conditions. Numerical analysis of the faunal assemblages shows that specific taxa, which were previously known to be uncommon in mangrove environments, are abundant in the Mamanguape River estuary. The atypical foraminiferal fauna found in the Mamanguape River estuary resembles shallow-water offshore assemblages, is characterized by high percent abundances of perforate and miliolid taxa, and contains only very few of the otherwise typical and numerically abundant agglutinated mangrove taxa. The unusual structure of the assemblages recorded provides insight into what combination of environmental variables controls their composition and novel perspectives to reconstruct past mangrove environments. Distribution, diversity, and species-specific analysis will provide guidance on the use of Brazilian mangrove foraminifera as indicators for the strength of tidal activity, pollution, and anoxia in coastal waters and sea-level reconstructions.
