Phylogenetic and environmental context of a Tournaisian tetrapod fauna
It is shown that atmospheric oxygen levels were stable across the Devonian/Carboniferous boundary, and did not inhibit the evolution of terrestriality, which suggests that tetrapod diversification was well established by the Tournaisian.
Prevalence and phenotypic antibiotic bioassay of methicillin-resistant Staphylococcus aureus in raw meats sold at various retail outlets in the cape coast metropolis of Ghana.
The prevalence of MRSA isolates in raw meat in most of the retail outlets in this study gives a warning signal for possible occurrence of food borne infections capable of producing outbreaks in the district.

The end‐Devonian mass extinction has been framed as a turning point in vertebrate evolution, enabling the radiation of tetrapods, chondrichthyans and actinopterygians. Until very recently ‘Romer's…
The postcranial anatomy of Whatcheeria deltae and its implications for the family Whatcheeriidae
The postcranial skeleton is described and the first full-body reconstruction of the early tetrapod Whatcheeria deltae from the Viséan of Iowa is presented, contributing to a revised diagnosis of the family Whatcheeriidae and a re-evaluation of fragmentary Devonian–Carboniferous fossils reported as ‘whatcheeriid’ but sharing no synapomorphies with the more precisely defined clade.

Patterns of growth throughout the lifetime of an animal reflect critical life history traits such as reproductive timing, physiology, and ecological interactions. The ancestral growth pattern for…
