Standard metabolic rate estimates in swimming respirometry were similar to those in resting respirometry when a three-parameter exponential or power function was used to extrapolate the swimming speed– relationship to zero swimming speed, and MMR estimates using the Ucrit protocol was higher than MMR derived from the 15 min chase protocol.

Oxygen- and capacity-limited thermal tolerance: blurring ecology and physiology
The Commentary by Portner, Bock and Mark elaborates on the oxygen- and capacity-limited thermal tolerance (OCLTT) hypothesis.

Maximum metabolic rates are estimated in four steady-swimming coral reef fishes - two body-caudal and two median-paired fin swimmers - using three different techniques to induce maximum performance.

The results suggest that the costs of swimming in unsteady flows are context dependent in labriform swimmers, and may be influenced by individual differences in the ability of fishes to adjust their fin beats to the flow environment.
Tracktor: Image‐based automated tracking of animal movement and behaviour
The main strengths of Tracktor lie in its ability to track single individuals under noisy conditions, its robustness to perturbations, and its capacity to track multiple unmarked individuals while maintaining their identities.

Public Data Archiving in Ecology and Evolution: How Well Are We Doing?
It is suggested that cultural shifts facilitating clearer benefits to authors are necessary to achieve high-quality PDA and key guidelines to help authors increase their data’s reuse potential and compliance with journal data policies are highlighted.
Ectoparasites increase swimming costs in a coral reef fish
It is shown that parasitized fish have higher standard metabolic rates, poorer aerobic capacities and lower maximum swimming speeds than non-parasitized fish, and the main cost of this ectoparasite is probably its direct effect on streamlining, reducing swimming performance at high speeds.
Localised intraspecific variation in the swimming phenotype of a coral reef fish across different wave exposures
Phenotypic variation among sites in traits functionally linked to swimming ability in the damselfish Acanthochromis polyacanthus is shown, suggesting that functional relationships among swimming phenotypes and water flow not only structure species assemblages, but can also shape patterns of phenotypic divergence within species.
