Expression patterns of melanin‐related genes are linked to crypsis and conspicuousness in a pumpkin toadlet

open access: yesMolecular Ecology, EarlyView.
Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

HABITATS AND DISPERSAL OF SOUTHERN AFRICAN ANURA [PDF]

open access: yesThe Journal of the Herpetological Association of Africa, 1975
The data required to make it possible to relate dispersal of southern African Anura to the habitats occupied are considered. Habitat must be defined in terms of breeding populations; data on the breeding seasons of the taxon under consideration are needed, with comparative data on possible competitors in the breeding sites. Possible routes of dispersal
