Intrasexually selected weapons
We propose a practical concept that distinguishes the particular kind of weaponry that has
evolved to be used in combat between individuals of the same species and sex, which we …

Phylogenetic systematics of dart-poison frogs and their relatives (Amphibia: Athesphatanura: Dendrobatidae)
The known diversity of dart-poison frog species has grown from 70 in the 1960s to 247 at
present, with no sign that the discovery of new species will wane in the foreseeable future …

Morphological diversity and evolution of egg and clutch structure in amphibians
The first part of this synthesis summarizes the morphology of the jelly layers surrounding an
amphibian ovum. We propose a standard terminology and discuss the evolution of jelly …

Ocular lens morphology is influenced by ecology and metamorphosis in frogs and toads
The shape and relative size of an ocular lens affect the focal length of the eye, with
consequences for visual acuity and sensitivity. Lenses are typically spherical in aquatic …

Ornithodoros faccinii n. sp. (Acari: Ixodida: Argasidae) parasitizing the frog Thoropa miliaris (Amphibia: Anura: Cycloramphidae) in Brazil
Background Most argasid ticks from the Neotropical region are parasites of mammals and
birds, with a few records from reptiles. Many species of the genus Ornithodoros are known …

Long-term habitat fragmentation is associated with reduced MHC IIB diversity and increased infections in amphibian hosts
Habitat fragmentation and wildlife disease are two widespread drivers of biodiversity loss,
yet few empirical studies have explored their interactions. In this study, we utilized a …

[HTML][HTML] Molecular phylogeny of Neotropical rock frogs reveals a long history of vicariant diversification in the Atlantic forest
Abstract The Brazilian Atlantic coastal forest is one of the most heterogeneous
morphoclimatic domains on earth and is thus an excellent region in which to examine the …

Egg-laying site, fecundity and degree of sexual size dimorphism in frogs
Female fecundity is an important selective force leading to female-biased sexual size
dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we …
