Standardization and repeatability is at the heart of all scientific research, yet very little
literature exists to standardize morphometric measurements within vertebrate groups. This is …

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 …

Frogs in the genus Amnirana (family Ranidae) are widely distributed across sub-Saharan
Africa and present a model system for exploring the relationship between diversification and …

The nuptial pad is a secondary sexual character found in anuran amphibians. It includes
modified epidermal and dermal tissues and is usually located on the first digit of the hand of …

The evolutionary success of anurans can be partially explained by the occurrence of free‐
living larvae. Tadpoles occupy several distict habitats, including the terrestrial environment …

Background Higher-level systematics in amphibians is relatively stable. However, recent
phylogenetic studies of African torrent-frogs have uncovered high divergence in these …

We performed surveys at several lower elevation sites surrounding Mt. Kupe, a mountain at
the southern edge of the Cameroonian Highlands. This work resulted in the sampling of 48 …

Amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been hypothesised to be
an indigenous parasite of African amphibians. In Cameroon, however, previous surveys in …

Torrent frogs of the genus Petropedetes Reichenow, 1874 as currently understood have a
disjunct distribution with species endemic to West, Central or East Africa. We herein present …

Semiterrestrial tadpoles live on wet rock surfaces and have evolved independently in at
least seven anuran families. They have a flat venter, laterally compressed keratinized jaws …
