Abstract:

Few studies document amphibian species composition from arid and semiarid environments. Scatteredbodies of water in the semi-arid and arid landscape around Pune, Maharashtra, India, could be viable amphibian habitats; however; information on amphibians using these bodies of water is not available. In a preliminary study, we assessed the amphibian diversity and population status in three wildlife sanctuaries and surrounding areas near Pune. We also compared the use of artificial and natural ponds by amphibians and surveyed the amphibians for the presence of the chytrid fungus.

Abstract:

Amphibians are the most severely threatened vertebrate group in terms of biodiversity. The microbiota that coexist in a mutualistic relationship with amphibians play a crucial role in shaping their health status, reproductive efficiency, and environmental adaptability. Understanding the relationship between amphibians and microbiota is vital for elucidating the causes of amphibian diseases and developing effective prevention and control techniques, which in turn is significant for enhancing the effectiveness of amphibian diversity conservation. The main findings of this article are as follows:

Abstract:

Streams are among the most threatened aquatic habitats for amphibians. Amphibians often demonstrate a complex community structure and investigations are mainly performed on pond-dwelling species, whereas data regarding stream-dwelling species is still scarce. The aim of this study was to evaluate the relevance of stream features and the effects of the occurrence of predatory fish on the community structure of amphibians. To assess the occurrence of breeding among amphibians (in Northern Apennine streams), sampling was performed on 57 stream and spring sites between early March and late May 201

Abstract:

Chytridiomycosis is an emerging infectious disease of amphibians that affects over 700 species on all continents where amphibians occur. The amphibian–chytridiomycosis system is complex, and the response of any amphibian species to chytrid depends on many aspects of the ecology and evolutionary history of the amphibian, the genotype and phenotype of the fungus, and how the biological and physical environment can mediate that interaction. Impacts of chytridiomycosis on amphibians are varied; some species have been driven extinct, populations of others have declined severely, whereas still other

Abstract:

Amphibians are currently the most threatened vertebrate class, with the disease chytridiomycosis being a major contributor to their global declines. Chytridiomycosis is a frequently fatal skin disease caused by the fungal pathogens Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal). The severity and extent of the impact of the infection caused by these pathogens across modern Amphibia are unprecedented in the history of vertebrate infectious diseases. The immune system of amphibians is thought to be largely similar to that of other jawed vertebrates, such as mamma

Abstract:

The exponential increase in species introductions during the Anthropocene has brought about a major loss of biodiversity. Amphibians have suffered large declines, with more than 16% considered to be threatened by invasive species. We conducted a global meta-analysis of the impacts of alien species on native amphibians to determine which aspects of amphibian ecology are most affected by plant, invertebrate, fish, amphibian, reptile, or mammal introductions. Measures of fitness were most strongly affected; amphibian performance was consistently lower in the presence of alien species. While expos

Abstract:

Background. Study of amphibian fauna as a necessary component of ecosystems is always relevant and requires a regular renewal of information, especially in protected areas. We conducted a field investigation of amphibians, a literature review and an inventory of the collections of herpetological funds in relation to three protected areas: the Roztochia Biosphere Reserve, the Yavorivskyi National Park, and the Cholgini Ornithological Reserve. Materials and Methods. The field study was performed by classical methods: route method with manual catching and with herpetological nets, vocalization me

Abstract:

The aim of this study was to analyze the richness, abundance and composition of the terrestrial amphibian assemblage in a flooded riparian forest fragment in a Neotropical region in the south of Brazil over a year (2002-2003). A total of 1,265 terrestrial amphibians were captured, representing 12 species and six families. Leiuperidae represented 41.7 and 56.3% of the total number of species and individuals captured, respectively. The amphibian richness and abundance were higher in the Spring-Summer than in the Autumn-Winter period, and these attributes did not change after the flood events. Ho

Abstract:

Amphibians are part of biodiversity that spread in various places in the world. Amphibians have an important role in maintaining the balance of the ecosystem as part of the food chain system. However, lack of public understanding caused the potential of Anura amphibians to have not been explored optimally hence research on Anura amphibians in the Wan Abdul Rachman Great Forest Park (Tahura WAR) is very important to support Anura's conservation efforts. This study aims to understand and identify the diversity of Anura order amphibians in the Protection and Utilization Blocks of the Tahura WAR o

Abstract:

Predicting the distribution of amphibians can be difficult because habitat suitability may depend on a variety of environmental and anthropogenic factors, including water quality of wetlands, geology of watersheds, and presence of invasive pathogens. Previous studies hypothesized that water chemistry may influence the rate of chytrid infection in amphibians where higher conductivity sites may have less infection. We sampled two watersheds in Grand Teton National Park and 3 watersheds adjacent to the park, and measured amphibian presence, chytrid infection, basic water quality, major ion concen

Abstract:

Amphibians have declined due to habitat loss and alteration. Sustainable Drainage Systems (SuDS) provide potential habitat for amphibians in urban landscapes. However, the contaminants they accumulate may cause increased pollutant exposure, and limited research has addressed whether differences in water quality between SuDS and natural ponds might restrict their use by amphibians. This study aimed to explore the effects of water quality on amphibian breeding and development in SuDS and natural ponds in East Kilbride, Scotland.

Abstract:

Amphibians constitute the class of vertebrates with the highest proportion of threatened species, with infectious diseases being considered among the greatest causes for their worldwide decline. Aquatic oomycetes, known as “water molds”, are fungus-like microorganisms that are ubiquitous in freshwater ecosystems and are capable of causing disease in a broad range of amphibian hosts. Various species of Achlya sp., Leptolegnia sp., Aphanomyces sp., and mainly, Saprolegnia sp., are responsible for mass die-offs in the early developmental stages of a wide range of amphibian populations through a d

Equivocal conclusions have been reached with respect to the effects of UV-B on amphibian populations.
