Cover: Three month old siblings of the American alligator (Alligator mississippiensis) raised under chronic hypoxia (12%O2 − left), normoxia (21% O2) and hyperoxia (30% O2 − right). Owerkowicz, Elsey and Hicks (pp. 1237−1247) compared growth and metabolism of alligators under O2 levels encountered during the 550 million years of vertebrate history. Chronic hypoxia constrained embryonic and hatchling growth, but hyperoxia enhanced growth and resting metabolism of hatchlings. Differences in alligator growth trajectories and metabolic rates under hypoxia, normoxia and hyperoxia suggest that reconstructions of the physiology of extinct vertebrates should take into account the prevalent atmospheric O2 conditions.

Researchers from the University of Montreal, Canada, reveal how tiny filter feeding barnacles and Daphnia entrap and consume minute droplets of crude oil, introducing the pollutant at the bottom of the food chain.
Patterns and processes in amphibious fish
-Review.png?versionId=3747)
In their Review, Keegan Lutek, Cassandra Donatelli and Emily Standen discuss the biomechanics and neural control of terrestrial locomotion in amphibious fish. They explore how locomotor mode depends on body shape, physical constraints and phylogeny.
