Amphibians form a major component of the diet of the otter Lutra lutra in several areas of its
wide geographic range. Yet, amphibian remains are rarely identified to species level and …

Aim As anuran reproduction is generally linked to the availability of water, frogs and toads
are particularly sensitive to climate. We tested the effect of climate on anuran reproductive …

Temporal variation represents an important component in understanding the structure of
ecological communities and species coexistence. We examined calling phenology of an …

Latitudinal variation in life-history traits has been the focus of numerous investigations, but
underlying hormonal mechanisms have received much less attention. Steroid hormones …

In the last century, a plethora of species have shown rapid phenological changes in
response to climate change. Among animals, amphibians exhibit some of the greatest …

The current study reports 29 cases of abnormal amplexus in some anuran species (Bombina
variegata, Bufo bufo, Epidalea viridis, Pelophylax ridibundus, Rana temporaria and Rana …

When and why many elusive frog species breed is unknown, particularly for species that
breed during short periods in remote locations. We used long-term natural history …

Organism survival and reproduction are affected by the ability to synchronize behaviour and
physiological condition to the season, typically using photoperiod. However, temperature …

Breeding sites are often a limited and ephemeral resource for rainforest frogs. This resource
limitation has driven the evolution of diverse reproductive strategies that increase offspring …

Background Most tropical regions have a climate characterized by marked seasonal rainfall
patterns, and these seasonal patterns of rainfall directly affect anuran activity. However, in …
