A new family of diverse skin peptides from the microhylid frog genus phrynomantis [PDF]
, 2020 A wide range of frogs produce skin poisons composed of bioactive peptides for defence against pathogens, parasites and predators. While several frog families have been thoroughly screened for skin-secreted peptides, others, like the Microhylidae, have ...

Warming increases activity in the common tropical frog Eleutherodactylus coqui
Climate Change Ecology, 2021 Tropical ecosystems are expected to experience climate warming, with predicted increases in drying and heat extremes in the coming years. Understanding how these changes will affect terrestrial vertebrates such as amphibians is limited.

Presence of an alien turtle accelerates hatching of common frog (Rana temporaria) tadpoles [PDF]
NeoBiota, 2022 The presence of a predator affects prey populations either by direct predation or by modifying various parts of their life history. We investigated whether the hatching time, developmental stage, and body size at hatching of common frog (Rana temporaria)

Frog foams and natural protein surfactants [PDF]
, 2017 Foams and surfactants are relatively rare in biology because of their potential to harm cell membranes and other delicate tissues. However, in recent work we have identified and characterized a number of natural surfactant proteins found in the foam ...

Revealing Carrier-Envelope Phase through Frequency Mixing and Interference in Frequency Resolved Optical Gating [PDF]
, 2015 We demonstrate that full temporal characterisation of few-cycle electromagnetic pulses, including retrieval of the carrier envelope phase (CEP), can be directly obtained from Frequency Resolved Optical Gating (FROG) techniques in which the interference ...
