La côte Atlantique française a été frappée par la tempête Xynthia en février 2010, ce qui a probablement affecté les espèces côtières. Des relevés de salinité associés à des relevés d’espèces (amphibiens), présentés dans l’étude de Lorrain-Soligon et al. (2021), ont été réalisés sur deux réserves côtières en Charente-Maritime (les réserves naturelles nationales de Moëze-Oléron et du marais d’Yves), afin d’étudier les effets de la submersion et de l’augmentation de la salinité résultante. Ces relevés ont permis de mettre en évidence les caractéristiques topographiques des sites pouvant limiter

Le glyphosate est un herbicide total foliaire systémique dont le principe actif est rarement utilisé seul mais le plus souvent mélangé à des formulants. Afin de faire la lumière sur ses effets toxicologiques sur les écosystèmes aquatiques, un travail de synthèse documentaire nous a permis d’établir sa toxicité sur les poissons, les invertébrés aquatiques et les amphibiens. Ainsi les CL50-96 h (Concentrations létales médianes sur 96 h) sur les poissons varient de 0,03 mg/L (Ictalurus punctatus) à 975 mg/L (Phalloceros caudimaculatus).

Bien que plus difficiles à quantifier, les effets indirects des routes sur la faune devraient être considérés au même titre que la mortalité routière, car certaines espèces évitent les abords des routes au moins durant une partie de l’année, ce qui peut mener à une fragmentation plus ou moins permanente de leurs populations. D’autre part, on observe chez plusieurs espèces un effet de bordure suivant lequel les abords des routes constituent un habitat de qualité marginale en raison du bruit, des substances et particules projetées par le passage des véhicules, des substances utilisées pour l’ent

It includes peaks ranging from 549 m to 2765 m above sea level and encompasses the montane complexes of northern Venezuela (including Isla de Margarita), an outlier at Santa Marta (Colombia), and ranges on the islands Trinidad and Tobago.

Abstract Many amphibians depend on wetland ecosystems for reproduction and survival, and coastal wetlands are not the exception. Recent advances on climate change research predict a reduction in land cover of coastal wetlands due to sea-level rise in response to global warming. Although this scenario will contribute to further amphibian population declines worldwide the impacts of sea-level rise and its related salt water intrusion on anuran assemblages in coastal wetlands remain largely unknown.

Introduction.The main environmental risks posed by roads are population depletion (deaths on roads) and barrier effects (habitat fragmentation). Barrier effects - animals avoid crossing roads, which leads to a decrease in the size and quality of habitat, optimal population size, reduced ability to find food and partner, increased genetic structuring and local extinction (Forman et al. 2003; Andrews et al. 2015; van der Ree et al. 2015). These risks against the background of other stressors, in particular the presence of invasive species, pollution, pesticide use, climate change, plant and anim

Abstract:

Crop residues are potential supplementary feed of small ruminants in Nigeria. However, arbitrary feeding of crop residues without due consideration to proportions and nutritive values could result in poor performance. Information on the proportions of mixed ration of different roughage sources for sheep is limited. Therefore, the effect of mixed ration of crop residues on the rumen fermentation and blood profiles of West African dwarf (WAD) sheep was investigated. Sixteen female WAD sheep with an average live weight of 8.10 ± 0.16kg were used in a completely randomised design with four animals

Abstract:

An investigation of the influence of the hydrofoil on load reduction performance during an amphibious aircraft landing on still and wavy water is conducted by solving the unsteady Reynolds-averaged Navier–Stokes equations coupled with the standard [Formula: see text] turbulence model in this paper. During the simulations, the numerical wave tank is realized by using the velocity-inlet boundary wave maker coupled with damping wave elimination techniques on the outlet, while the volume of fluid model is employed to track the water–air interface. Subsequently, the effects of geometric parameters

Abstract:

Understanding what regulates population sizes of organisms with complex life cycles is challenging because limits on population sizes can occur at any stage or transition. We extend a conceptual framework to explore whether numbers of successfully laid eggs determine densities of later stages in insects, fish, amphibians, and snails inhabiting marine, freshwater, or terrestrial habitats. Our review suggests novel hypotheses, which propose characteristics of species or environments that create spatial variation in egg densities and predict when such patterns are maintained throughout subsequent

Abstract:

ABSTRACT Thymus plasticity following gonadectomy or sex hormone replacement has long since exemplified sex hormone effects on the immune system in mammals and, to a lesser extent, in ‘lower vertebrates’, including amphibians and fish. Nevertheless, the underlying physiological significances as well as the ontogenetic establishment of this crosstalk remain largely unknown. Here, we used a teleost fish, the European sea bass, Dicentrarchus labrax, to investigate: (1) whether the regulation of thymus plasticity relies on resource trade-off with somatic growth and reproductive investment and (2) i

Abstract:

AbstractProximity to the seashore is a critical structuring factor of coastal wetlands due to its influence on varying sources of nutrients (marine and terrestrial) and on the spatial gradient of salinity (higher salinity closer to the seashore). The spatial gradient of salinity may impact organisms because most organisms need to maintain an osmotic balance. Osmoregulation is energetically costly, and exposure to salinity should induce a trade‐off in energetic allocation between osmoregulation and other competing functions such as growth rates and movement patterns. In this study, we used a ca

Abstract:

ABSTRACT Bacterial assemblages on amphibian skin may play an important role in protecting hosts against infection. In hosts that occur over a range of environments, geographic variation in composition of bacterial assemblages might be due to direct effects of local factors and/or to evolved characteristics of the host. Invasive cane toads (Rhinella marina) are an ideal candidate to evaluate environmental and genetic mechanisms, because toads have evolved major shifts in physiology, morphology, and behavior during their brief history in Australia. We used samples from free-ranging toads to quan

Abstract:

Pacific tree frogs (Psedacris regilla) and California tree frogs (P. cadaverina), native to Southern California, have adapted to frequent periods of drought. These tree frogs show both behavioral and physiological adaptations that help diminish water loss to their environment. However, despite these adaptations, tree frogs may still experience periods of dehydration in their natural habitat. Dehydration significantly decreases aerobic scope in amphibians; frogs being more susceptible than toads. When dehydrated, semi‐aquatic frogs rely heavily on anaerobic metabolism, which has been shown to i
