Abstract:

La nature et la distribution des phénotypes quantitatifs représentent une connaissance de base pour l’application des méthodologies génétiques dans les plans de sélection des animaux domestiques. Afin d’illustrer l’action de facteurs non génétiques d’aridité sur la distribution phénotypique des performances individuelles de la croissance des chevreaux de la population locale élevés dans des conditions restrictives et irrégulières, 945 chevreaux issus de 285 chèvres et 19 boucs, nés durant la période 1998–2014, ont été étudiés par l’analyse des distributions des poids jusqu’à 150 jours d’âge. La dispersion des poids représentait une expression collective des génotypes des chevreaux dans les conditions de l’étude avec des variations dues à la fois aux effets génétiques et environnementaux. L’hypothèse de la normalité n’a été vérifiée qu’aux âges de 10 jours et 30 jours quand les chevreaux étaient surtout nourris sous la mère et n’étaient pas directement dépendants des ressources alimentaires du parcours aride. Durant une année défavorable, les performances enregistrées ont suivi une distribution particulière expliquée par le fait que les chevreaux performants ont été incapables d’extérioriser leur supériorité. Par conséquent, le milieu aride a réduit les performances de la population caprine locale. En outre, il a limité l’expression de quelques génotypes fortement productifs. Cette spécificité de l’action du milieu aride incite à un approfondissement indispensable pour ajuster les méthodes de sélection aux conditions des milieux restrictifs et des groupes génétiques adaptés.

Abstract:

Le traitement, le conditionnement et la transformation des produits de la pêche génèrent une quantité importante de sous-produits de la pêche (SPP). Ces derniers sont constitués notamment par des têtes, des viscères, de la peau, des écailles, des arêtes, des queues, etc. A défaut d’une stratégie de valorisation, ils sont jetés et deviennent alors source de pollution, ce qui pose un problème environnemental et sanitaire. Face à cette contrainte, l’équipe du laboratoire Valoremar de l’Institut halieutique et des sciences marines a mis en oeuvre un programme de recherche étudiant la possibilité de valoriser les SPP en alimentation avicole. L’étude a été initiée en raison de la présence probable de molécules valorisables dans les SPP, notamment des protéines. Nous avons ainsi constitué la base protéique de l’alimentation des poulets avec de la farine de SPP (1), mélangée à d’autres ingrédients disponibles, sources de matières énergétiques, minéraux, vitamines…Au laboratoire, la farine a été préparée avec des sous-produits de poulpe et de calmar fournis par une société de pêche basée à Toliara, suivant le procédé de transformation rapporté par le département de la pêche de l’Organisation des Nations unies pour l’alimentation et l’agriculture (2). Il s’agit d’un traitement thermique visant à séparer les fractions solides, huileuses et aqueuses. La farine de SPP a été produite à partir des fractions solides et a permis d’élaborer les rations expérimentales (1) (tableau I). L’introduction des farines de poulpe et de calamar s’est faite en remplaçant 50 p. 100 (lots C50 et P50) ou 100 p. 100 (lots C100 et P100) du tourteau d’arachide dans un aliment à base de son de maïs et de son de riz.Les poulets étaient des mâles de race locale d’un poids moyen de 250 g à l’entrée et de 485 g en moyenne après la quarantaine. Le test a été réalisé en station sur cinq lots de 25 poulets dont un lot témoin. Les poulets ont été élevés dans les mêmes conditions d’habitat et ont reçu leur nourriture respective de 120 g par tête par jour, en deux distributions (matin et après-midi). La croissance des animaux a été suivie jusqu’à 12 semaines. Un autre essai, utilisant des régimes comparables, a porté sur le transfert des techniques aux bénéficiaires. Il a été réalisé dans une ferme pilote et conduit par l’association Ezaka de Saint Augustin, district de Toliara II, région Atsimo Andrefana.Le rendement de la production de farines de SPP a été de 15 p. 100. Les farines produites étaient très riches en protéines, avec des teneurs de 60,8 p. 100 pour les sous-produits de poulpe et de 52,1 p. 100 pour ceux de calmar. Introduites dans les aliments composés (tableau I), les farines des sous-produits de poulpe et de calmar ont permis un gain moyen de poids quotidien allant jusqu’à 17,4 g pour le lot P100. La figure 1 montre que le poids vif des poulets des cinq lots a varié, après 12 semaines d’expérience, en fonction de la nature et de la quantité des SPP utilisés, avec des valeurs atteignant 1 943 g pour le lot P100 et 1 614 g pour le lot C100, contre 1 199 g pour le lot témoin.Dans la ferme pilote de Saint Augustin, les bénéficiaires ont utilisé les sous-produits des poissons (figure 2). Le poids vif final de 1 683 g pour les poulets nourris avec des aliments à base de la farine de sous-produits de poisson a été supérieur à celui du lot témoin.Cette étude montre que les SPP, existant en quantité importante sur le littoral sud-ouest de Madagascar, peuvent être valorisés. Si Toliara abonde en SPP, essentiellement des sous-produits de poulpe et de calmar générés par les sociétés de pêche, Saint Augustin génère plutôt des SPP issus des ménages ou des restaurants. On estime par exemple que 200 tonnes par an de SPP sont générées par une société d’exportation des produits halieutiques basée à Toliara.Le transfert des techniques de valorisation des SPP aux bénéficiaires a été réalisé à travers la mise en place d’une ferme pilote. Ceci permet de confirmer l’impact de l’étude dans le monde rural. Le développement de la filière avicole serait ainsi accueilli favorablement dans cette localité en tant qu’activité générant des revenus après la pêche. Au laboratoire, l’étude d’une voie de valorisation en alimentation piscicole a attiré l’attention de l’équipe en utilisant non seulement les farines des SPP mais aussi les hydrolysats des protéines des SPP.Les auteurs remercient le Service de coopération et d´actions culturelles de l’ambassade de France à Madagascar pour l’appui financier du projet SPP.

Abstract:

La distribution de la fluméthrine dans le pelage de bovins après application topique ("pour-on") a été déterminée par analyse chimique. La fluméthrine a été appliquée à 1 mg de substance active (s.a.) par kg de poids corporel, le long de la ligne dorsale. Il a été démontré que le produit pouvait être retrouvé dans tous les échantillons de poils prélevés de régions dorsales, latérales, ventrales et distales 1 jour après l'application, dans des concentrations allant de 670 à 1 mg de s.a. par g de poils, selon la distance du site d'application. Trois, 5 et 10 jours après l'application ces concentrations variaient respectivement de 125-1,5, 23-1 et 44-0,9 mg de s.a. Une corrélation de ces valeurs avec la surface corporelle de bovins montre qu'il y avait plus de 0,01 mg de s.a./cm2 de surface corporelle sur toutes les régions du corps et tous les jours des prélèvements. Cette quantité est suffisante pour une activité acaricide efficace, comme l'ont montré des données de laboratoire et de terrain.

Abstract:

This study presents the results of research on a wastewater treatment system with four identical facultative ponds in series with step-feeding and recirculation (SFFPR). Four modes of distribution of the influent were studied, which were (in percentages of the inflow per pond): C1 = 25/25/25/25; C2 = 50/20/20/10; C3 = 50/50/0/0; C4 = 100/0/0/0. The organic loading applied to the four ponds overall was around 200 kg BOD5/ha.d. The distribution C4 = 100/0/0/0 was selected for studying the recycle rate. Three recycling rates were studied: 0.5Q, 1Q and 2Q. COD and BOD5 removal efficiencies were high whatever the step-feed distribution. For the distribution C1 and C2, the four ponds were homogeneous. The equal distribution of organic loading rate in C2 distribution was most beneficial for algal growth. For piston pattern distributions (C3 and C4), the ponds receiving the highest loading showed a bacterial biomass higher than that of the primary production. Increasing the recirculation rate seemed to lead towards homogenisation of the ponds, while a decrease appeared to lead to their individualisation and increased their productivity. The SFFPR constitutes a stage of the treatment process which can replace the facultative stage; it produces a high effluent quality and decreases land area requirements.

Abstract:

A sequence of random variables X(λ,n) with parameters 0 < λ≤1, n∈N is investigated. For n→∞ X(λ,n) converges in distribution to a random variable Pois(λ) obeying Poisson's law with the parameter λ. At a fixed value n all moments of the distribution of a random variable X(λ,n) of order k≤n coincide with the moments of the distribution of Pois(λ). For the value of the parameter λ=1, the random variable X(1,n) coincides with the random variable equal to the number of «fixed» points in case of random permutations of the set of elements of power n.

Abstract:

AbstractThe talitrid amphipod Talitrus saltator has a wide distribution along European Atlantic and Mediterranean sandy shores. Previous research had estimated genetic differences among populations with iso-enzyme electrophoresis, as well as differences in behavioural adaptation related to ecological features. In this study morphometric differences among four Mediterranean (Italian coasts) and three Atlantic (Portuguese and Welsh coasts) populations were estimated, which may give information on population dynamics and adaptability to environmental constraints. The localities chosen differed with regard to the following characteristics: sheltered/exposed shorelines, tidal/non-tidal shores, presence/absence of detritus, Atlantic/Mediterranean climate, high/low human frequentation. Samples of each population were collected in a standardized way and fresh individuals were weighed, their body lengths and eye diameters were measured, and the number of eggs in the female brood-pouches and the articles of each antenna were counted. The results were as follows: (i) an unbalanced sex ratio in each population studied, females being more abundant than males; (ii) significant differences between Mediterranean and Atlantic population groups as to weight and body length distributions, the Atlantic talitrids being larger than the Mediterranean ones; (iii) differences in eye colour, normally black in this species, but one Mediterranean and two Atlantic populations presented a certain proportion of blue-eyed individuals; (iv) right-left asymmetry of eye surface areas (right eye bigger than left one) in all populations, with one exception. The differences found among populations do not seem to follow a geographic cline, but could depend on ecological features of the localities. L'amphipode talitride Talitrus saltator a une large distribution le long des cotes sableuses de l'Atlantique europeen et de la Mediterranee. Des recherches anterieures ont evalue les differences genetiques parmi les populations par electrophorese iso-enzymatique, ainsi que les differences de comportement adaptatif en relation avec les facteurs de l'environnement. Dans cette etude, les differences morphometriques parmi quatre populations mediterraneennes (cotes italiennes) et trois populations atlantiques (cotes portugaises et galoises) ont ete evaluees, ce qui peut donner des informations sur les dynamiques de population et sur l'adaptabilite aux contraintes de l'environnement. Les localites choisies different en ce qui concerne les caracteristiques suivantes: lignes cotieres abritees/exposees, cotes a maree ou non, presence/absence de detritus, climat atlantique/mediterraneen, haute/basse frequentation humaine. Les echantillons de chaque population ont ete preleves suivant un meme standard et les individus frais ont ete peses, la longueur du corps et le diametre de l'oeil mesures, le nombre d'oeufs dans la poche incubatrice et les articles de chaque antenne comptes. Les resultats ont ete les suivants: (i) une sex ratio non equilibree dans toutes les populations etudiees, les femelles etant plus nombreuses que les males; (ii) des differences significatives entre les groupes de populations atlantiques et mediterraneens, quant a la distribution des poids et des longueurs du corps, les individus atlantiques etant plus grands que les mediterraneens; (iii) des differences dans la couleur de l'oeil, normalement noir chez cette espece, mais une population de l'Atlantique et deux de Mediterranee presentaient une certaine proportion d'individus a yeux bleus; (iv) une asymetrie droite-gauche de la surface de l'oeil (oeil droit plus gros que le gauche) dans toutes les populations, avec une exception. Les differences observees entre les populations ne semblent pas suivre un gradient geographique, mais pourraient dependre des caracteristiques ecologiques des localites.

Abstract:

The paper presents results from an experimental and numerical study of wind-induced flows and transportation patterns in highway wet detention ponds. The study presented here is part of a general investigation on road runoff and pollution in respect to wet detention ponds. The objective is to evaluate the quality of long term simulations based on historical rain series of the pollutant discharges from roads and highways. The idea of this paper is to evaluate the effects of wind on the retention time and compare the retention time for the situation of a spatial uniform wind shear stress with the situation of a “real” spatial non-uniform shear stress distribution on the surface of the pond. The result of this paper shows that wind plays a dominant role for the retention time and flow pattern. Furthermore, the results shows that the differences in retention time between the use of uniform and non-uniform wind field distributions are not significant to this study.

Abstract:

Aerial surveys provide an assessment of the offshore distribution of gray whales and an estimate of the proportion of whales that migrate beyond the visual range of shore-based observers. Six surveys were conducted concurrent with shore-based surveys during 1979, 1980, 1988, 1993, 1994 and 1996. Annual differences were tested for in the distribution of whales within an area 3 n.miles north and south of Granite Canyon, and it was found that the distributions within 3 n.miles of the shore differed by year but the shifts in the distribution were minor ( < 0.3 n.miles). The inshore ( < 2.25 n.miles) and offshore ( > 2.25 n.miles) distribution of gray whale pods did not differ significantly between survey years. An average of 4.76% (SE = 0.85%) of the whale pods were observed beyond 2.25 n.miles and only 1.28% (SE = 0.07%) beyond 3 n.miles.

Abstract:

The significance of choosing optimal locations for emergency facilities is emphasized both in natural disasters and public health emergencies like pandemics. To ensure effective management of emergency logistics, procurement, and distribution, it is crucial to consider the establishment of facilities such as Points-of-Dispensing (PODs) that facilitate fast and efficient distribution. Consequently, when deciding on the location of logistics warehouses as part of emergency logistics management, it is essential to take into account the positioning of temporary facilities like PODs. We propose an integer programming model that integrates the Maximal Covering Location Problem (MCLP) and includes capacity constraints. Additionally, we conducted a case study in Incheon Metropolitan City to compare the outcomes. Through this case analysis, we present the optimal subset of temporary logistics warehouses, enabling the development of an optimal location-distribution plan. The study holds three main implications: (1) it provides an optimized selection of locations that aids in the decision-making process for policies; (2) the empirical analysis using real data allows for its application in similar disaster management situations; (3) the proposed model can be utilized to determine the positioning of various public facilities

Abstract:

This paper deals with the modeling of two different solar ponds which has some different structural parameters such as aboveground and underground, and its performance evaluation. The solar pond system generally consists of three zones, and the densities of these zones decrease from the bottom of the pond to the surface. The most significant decrease in the density distribution of the salt between bottom and up of the pond is the gradient zone. The convective heat loss in the solar pond is prevented with this zone. In this study, aboveground and underground solar ponds were modeled at the same dimensions, but different structural parameters in the same conditions. In this model, the temperature distributions of the solar pond were obtained during a year. The thermal performances of the solar pond were calculated and the results were compared with an experiment. This study shows that the efficiency of the aboveground solar pond is observed to be a maximum of 25.93% in July, a minimum of 4.53% in January. Furthermore, the efficiency of the underground solar pond is observed to be a maximum of 21.49% in July, a minimum of 6.55% in January. This study indicates that the underground construction of solar ponds, designed to be insulated using appropriate insulation materials, is found to be more efficient with respect to the aboveground pond.

Abstract:

Environmental and genetic factors influence fish spawning periodicity (i.e., the distribution of spawning events during the breeding season), but their relative contributions have rarely been evaluated. We evaluated the relative contribution of genetic and environmental effects on spawning periodicity by rearing Florida largemouth bass (FLMB, Micropterus salmoides floridanus) from Lake Okeechobee and intergrade largemouth bass (ILMB, Micropterus salmoides salmoides × M. s. floridanus) from Lake Seminole in a similar environment. Fish from each genetic source population were translocated to experimental ponds at an intermediate latitude in Gainesville, Florida, in September 2003. We used estimated ages of offspring as an index of spawning events to compare spawning distributions between brood sources in ponds and related those results to spawning distributions at source populations for 2004. FLMB began spawning earlier than ILMB in all ponds, and FLMB had a longer spawning season than ILMB. Similarly, FLMB at Lake Okeechobee began spawning earlier and had a longer spawning season than ILMB at Lake Seminole. Environmental factors (e.g., temperature effects) influenced spawning periodicity for both FLMB and ILMB, but spawning periodicity was also influenced by genetic composition in ponds because translocated fish reflected characteristics of their source populations. Thus, both environmental factors and genetic composition influenced spawning periodicity.

Abstract:

In 2010 and 2017, respectively, the manuscripts Location and Analysis of Emergency Management Point of Distributions (PODS) for Hurricane Ike and Use of Geographical Information System Data For Emergency Management Points of Distribution Analysis With POD Locator 2.0 were published in the Journal of Emergency Management. These manuscripts described the use of the University of Houston POD Locator software to determine the location of Points of Distribution under emergency conditions. This software achieved a 46 percent improvement in POD locations in comparison to those actually selected during the event. However, a limitation of those research efforts was the absence of the potential effects of flood waters as experienced in the Houston Harris County area during Hurricane Harvey in 2017. This research effort focuses on the effects of flood water in determining the location of different PODs under these conditions in comparison to the PODs identified by Hurricane Harvey. The results indicate a statistically significant difference at an alpha level of 0.05 between using and not using flood data when determining the location of PODs. The use of flood data also yielded a 46.5 percent in travel distance reduction over the actual 26 POD locations chosen in Ike.

Abstract:

AbstractThe distribution of Bufo bufo, Rana esculenta complex, Rana dalmatina, Hyla arborea, Triturus carnifex and Triturus vulgaris were studied in 61 ponds in NW Italy, in relation to a number of specific habitat features. Multivariate analysis identifies those habitat parameters which classify ponds into characteristic habitat groups. Several multivariate statistical tests were carried out to identify habitat features characteristic of each species and to delineate ecological factors that influence amphibian distributions and size of breeding populations. Variables scored at each pond were: extent of aquatic vegetational cover, age of the pond, terrestrial habitats occurring near the ponds, degree of human interference, surface areas, maximum depth, chemical water factors (such as pH and water hardness). The first four of these parameters influenced breeding population presence of R. dalmatina, H. arborea, T. vulgaris and T. cristatus significantly. Densities of H. arborea, R. dalmatina, B. bufo and R. esculenta were apparently unaffected by any of these parameters; these species seem to colonize available habitats almost at random.

Abstract:

AbstractThis paper investigates the impact of street pattern, metro stations, and density of urban functions on pedestrian distribution in Tianjin, China. Thirteen neighborhoods are selected from the city center and suburbs. Pedestrian and vehicle volumes are observed through detailed gate count from 703 street segments in these neighborhoods. Regression models are constructed to analyze the impact of the street pattern, points of interest (POIs), and vehicle and metro accessibility on pedestrian volumes in each neighborhood and across the city. The results show that when analyzing all neighborhoods together, local street connectivity and POIs had a strong influence on pedestrian distribution. Proximity to metro stations and vehicle accessibility had a minor impact. When analyzing each neighborhood separately, both local- and city-scale street patterns affect pedestrian distributions. These findings suggest that the street pattern provides a base layer for metro stations to attract both the emergence of active urban functions and pedestrian movement.

Abstract:

On September 13, 2008, Hurricane Ike caused massive destruction along the Gulf Coast of the United States. In response to subsistence shortages caused by infrastructure damage, government officials opened 26 Points of Distributions (PODs) to distribute food, water, and ice. To analyze the accessibility of these PODs, a Microsoft Windows software program POD Locator was developed by the researchers. This program calculated the average distance of each area residents’ home location to the closest of the 26 PODs to be 6.41 miles. In comparison, POD Locator identified an alternative set of 26 PODs with an average distance of 3.71 miles for an average reduction in travel of 46 percent. POD Locator also identified the fact that similar performance to the actual 26 PODs was achievable with only 10 PODs.

Abstract:

Abstract In-shell peanut sales provide a consistent market for large-seeded virginia-type peanuts. In this market, maintenance of a high quality product, which includes fresh roasted peanut flavor, is a recurring challenge. A maturity-seed size-quality relationship has been established for shelled peanuts. To determine if this relationship is true for in-shell peanuts, the relationships of maturity, pod size, and seed size were investigated. In two crop years (1992 and 1993) and on four to five harvest dates, virginia-type peanuts (cv. NC 9) were harvested at Lewiston, NC and sorted into hull scrape maturity classes: black, brown, orange B, orange A, and yellow. After pods were dried, they were screened to obtain the pod size distribution. Sized pods were hand-shelled, and the seed were screened to obtain the seed size distribution from each pod size from each maturity class. Hull scrape pod maturity profiles revealed a decrease of ca. 14% in yellow/orange A and an increase of ca. 14% in brown/black over the 4- to 7-d harvest period. Overall, pod size distribution did not change over time although slight differences were noted between years. Pod size distributions within individual maturity classes were more variable. The data indicated that the Jumbo in-shell grade contained higher percentages of brown and black maturity classes than the fancy grade. Fancy grades contained 26-49% immature pods (yellow and orange A maturity classes).

Abstract:

The present study was carried out to evaluate the distribution and diversity of oligochaete fauna in selected ponds of Thiruvananthapuram district in Kerala, South India. The sediment samples were collected from three ponds seasonally during the period December 2006 to November 2008. In the study, 10 oligochaete species which belong to 8 genera were identified in three selected ponds. These include Dero digitata, Dero nivea, Dero obtusa, Pristina longiseta, Aulophorus furcatus, Stylaria fossularis, Chaetogaster spp., Aeolosoma spp., Tubifex tubifex and Limnodrilus hoffmeisteri. Tubifex tubifex and Limnodrilus hoffmeisteri are the pollution-indicator oligochaete species identified in the fresh water ponds, which reveals that the studied ponds are subjected to pollution.

Abstract:

Surveys of 196 lakes and ponds in Western Australia showed that most species of the centropagid copepods Boeckella, Calamoecia and Hemiboeckella have low incidence, although a few are common within restricted geographic areas. Records of co-occurrences indicate that many species have broadly overlapping ecological requirements, suggesting that dispersal or historical events are more important determinants of incidence and distribution than is colonization ability. However, some species prefer or are restricted to specialized environments. The roles of history, recent natural dispersal, and recent human-mediated dispersal in moulding present-day distributions are discussed. It is concluded that most species have low dispersal ability and that historical events have played a major role in determining present-day distribution patterns, although local dispersal and some human-mediated local and long-range dispersal have influenced incidence and distribution patterns.

Abstract:

The objective of this work was to identify monthly and annual oscillations and trends in meteorological variables: maximum and minimum air temperatures, precipitation, and relative humidity, number of rainy days, total sunshine, wind intensity and cloud cover. We used the theoretical probability distribution: Weibull, Log-normal and Logistics to adjust the values of the variables mentioned above. The Kolmogorov-Smirnov test was used to verify the adjustment of the theoretical functions. The study of the spatial temporal behavior of rainfall and monthly, maximum and minimum temperatures, relative humidity, insolation, cloud cover and wind used was acquired from the National Institute of Meteorology, the data period comprising the series from 1962 to 2015. For The determination of the theoretical distributions of probability adjusted to the annual extremes of precipitation, maximum and minimum temperature of the air, total isolation and relative humidity, cloud cover and wind intensity, were used the maximum likelihood methods to estimate the parameters of the distributions. The Kolmogorov-Smirnov test was used to compare the fit and select the best theoretical distributions. The adjustments were also evaluated in graphs. Deforestation of native vegetation for the construction of districts, favelas and buildings above six floors, as well as high burnings, has contributed to the high rates of desertification, silting up rivers, streams, streams, wells, ponds, ponds and lagoons.

Abstract:

Metazoan parasites of Salmo salar and Salvelinus fontinalis were studied at eight sites in insular Newfoundland. The locations included water bodies of various sizes (<1, 1–100, and >100 ha) and depths (<1, 1–5, and >5 m). Nine of 14 parasite species were salmonid specialists and generally had wider geographic distributions than the remaining generalists, with one exception (Echinorhynchus lateralis). The distributions of Crepidostomum farionis, Sterliadochona ephemeridarum, and E. lateralis appeared to be facilitated by the widespread distribution of intermediate hosts. Larval digeneans (Apophallus imperator, Diplostomum sp., and Tetracotyle sp.) were typically associated with shallow medium-sized lakes. Species using limnetic copepods as intermediate hosts (Philonema agubernaculum, Eubothrium salvelini, and Diphyllobothrium sp.) were most often found in fishes inhabiting the deeper lakes. Small ponds had low parasite richness (R = 5); medium and large lakes had similar richness (R = 9–11). Jaccard's index and cluster analysis revealed that fishes in the small ponds and deep lakes had inherently different parasites from fishes of the shallow medium-sized lakes, the latter containing fishes parasitized by larval digeneans. Based on the study it was concluded that lake depth is a fundamental factor determining the structure of parasite communities in salmonids in insular Newfoundland.

Abstract:

ABSTRACTIce cliffs and ponds on debris-covered glaciers have received increased attention due to their role in amplifying local melt. However, very few studies have looked at these features on the catchment scale to determine their patterns and changes in space and time. We have compiled a detailed inventory of cliffs and ponds in the Langtang catchment, central Himalaya, from six high-resolution satellite orthoimages and DEMs between 2006 and 2015, and a historic orthophoto from 1974. Cliffs cover between 1.4% (± 0.4%) in the dry and 3.4% (± 0.9%) in the wet seasons and ponds between 0.6% (± 0.1%) and 1.6% (± 0.3%) of the total debris-covered tongues. We find large variations between seasons, as cliffs and ponds tend to grow in the wetter monsoon period, but there is no obvious trend in total area over the study period. The inventory further shows that cliffs are predominately north-facing irrespective of the glacier flow direction. Both cliffs and ponds appear in higher densities several hundred metres from the terminus in areas where tributaries reach the main glacier tongue. On the largest glacier in the catchment ~10% of all cliffs and ponds persisted over nearly a decade.

Abstract:

The current study assessed the diversity and abundance of phytoplankton genera in two Kenyan saltworks (Tana and Kurawa) in March and September 2021. Water samples were obtained from ponds with salinities ranging from 30 to 200 ppt by filtering 40 l of water using a 20-μm phytoplankton net. Seventy-six genera of phytoplankton were identified. Genera richness, evenness and diversity decreased with increasing salinity while phytoplankton abundance increased with increasing salinity. Higher phytoplankton densities were observed in the Tana than in the Kurawa saltworks. Ponds of <100 ppt were dominated by Dinophyceae and Bacillariophyceae which accounted for >90 % of the phytoplankton community. Ponds of salinities >100 ppt were dominated by Cyanophyceae which accounted for >90 % of the phytoplankton community. From the results it was concluded that Kenyan saltworks host diverse phytoplankton genera whose richness decreases with increasing salinity and varies with seasons. The present data describes variation of phytoplankton assemblages in salt ponds between two selected seasons, but several samplings throughout the year would be more appropriate to describe variations of phytoplankton with season in these salt ponds.

Abstract:

SUMMARYParasites can influence host population dynamics, community composition and evolution. Prediction of these effects, however, requires an understanding of the influence of ecological context on parasite distributions and the consequences of infection for host fitness. We address these issues with an amphibian – trematode (Digenea: Echinostomatidae) host–parasite system. We initially performed a field survey of trematode infection in first (snail) and second (larval green frog, Rana clamitans) intermediate hosts over 5 years across a landscape of 23 ponds in southeastern Michigan. We then combined this study with a tadpole enclosure experiment in eight ponds. We found echinostomes in all ponds during the survey, although infection levels in both snails and amphibians differed across ponds and years. Echinostome prevalence (proportion of hosts infected) in snails also changed seasonally depending on host species, and abundance (parasites per host) in tadpoles depended on host size and prevalence in snails. The enclosure experiment demonstrated that infection varied at sites within ponds, and tadpole survival was lower in enclosures with higher echinostome abundance. The observed effects enhance our ability to predict when and where host–parasite interactions will occur and the potential fitness consequences of infection, with implications for population and community dynamics, evolution and conservation.
