Pesticide use is well known to be detrimental for maintaining biodiversity in the agricultural landscape. Amphibians are especially affected by these agrochemicals. In particular, these animals’ high sensitivity was demonstrated for glyphosate-based herbicides which are dominating the world market today. Pesticide impacts are influenced by several co-stressors, and we for the first time link th...

Emerging infectious diseases may be contributing to the global decline of amphibian populations. In particular, chytridiomycosis, a cutaneous fungal infection of amphibians caused by the chytrid Batrachochytrium dendrobatidis, gained attention in the 1990s as an apparently new pathogen. This fungus has been implicated as the causative agent of widespread mortalities among wild amphibians in geo...

Urbanisation currently threatens over one-third of the world’s known amphibian species. The main threats of urbanisation to amphibian populations are habitat loss, habitat fragmentation and isolation, and degradation of habitat quality. A complex array of interacting biotic and abiotic factors impact amphibians in urban and urbanising landscapes. These can lead to a decrease in species richness...

This review covers the literature on the subject of biologically active peptides from the glands of amphibians. These include neuropeptides, antimicrobial and anticancer active peptides, antiviral agents, fungicides and peptides which complex with Ca calmodulin. Other topics covered include sex pheromones from amphibians, and the use of peptide profiling to differentiate between species and dif...
