The evolution of coloration and toxicity in the poison frog family (Dendrobatidae)
(East Carolina University, 2001-05-22)
The poison frogs (family Dendrobatidae) are terrestrial anuran
amphibians displaying a wide range of coloration and toxicity.
These frogs generally have been considered to be aposematic, but
relatively little ...
The evolution of parental care and egg size: a comparative analysis in frogs
(East Carolina University, 2006-03-22)
The evolution of parental care and egg size has attracted considerable attention and theoretical debate. Several different hypotheses have been proposed concerning the trajectories of parental care and egg size evolution ...
Cadherins in maternal-foetal interactions: red queen with a green beard?
(East Carolina University, 2005-03-22)
Cadherins are homophilic cell surface adhesion proteins, some of which mediate interactions between maternal and foetal tissues during mammalian pregnancy. David Haig suggested that these proteins may
exhibit ‘green-beard ...
Convergent evolution of bright coloration and toxicity in frogs
(East Carolina University, 2003-10-28)
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis.
(East Carolina University, 2001-12-07)
Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single ...
Tactical reproductive parasitism via larval cannibalism in Peruvian poison frogs
(East Carolina University, 2009-04-23)
We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabi- lis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the ...
