Physiological plasticity increases resilience of ectothermic animals to climate change
TLDR
Research synthesizing the current state of knowledge about physiological plasticity in ectotherms shows that freshwater and marine animals seem to have a greater capacity for acclimation than terrestrial ones.

Antarctic fish can compensate for rising temperatures: thermal acclimation of cardiac performance in Pagothenia borchgrevinki
TLDR
In spite of living in a highly stenothermal cold environment, P. borchgrevinki demonstrated the capacity to thermally acclimate cardiac function to elevated temperatures, thereby allowing the maintenance of factorial scope and the support of aerobic swimming at higher temperatures.

A falsification of the thermal specialization paradigm: compensation for elevated temperatures in Antarctic fishes
TLDR
This work shows that the Antarctic fish Pagothenia borchgrevinki has retained the capacity to compensate for chronic temperature change, and falsification of the specialization paradigm indicates that the effect of climate change on species distribution and extinction may be overestimated by current models of global warming.

Predicting the physiological performance of ectotherms in fluctuating thermal environments
TLDR
This work determined whether reaction norms based on performance at constant temperatures could be used to predict embryonic and larval performance of anurans at fluctuating temperatures and generated hypotheses about the effects of stress and acclimation on the predictability of performance in variable environments.

ADAPTATION OF RAINBOW FISH TO LAKE AND STREAM HABITATS
TLDR
Replication of muscle and Ucrit phenotypes across same habitat populations within and/or among species was suggestive of adaptation, but the common garden experiment did not confirm a genetic basis to these associations.

V-Track: software for analysing and visualising animal movement from acoustic telemetry detections
TLDR
V-Track is a package written within the R-programming language, and a graphical user interface is also provided, which provides software functionality for defining and quantifying behaviour in acoustically tagged marine and freshwater vertebrates.

Sexual Maturity Can Double Heart Mass and Cardiac Power Output in Male Rainbow Trout
TLDR
Mature male rainbow trout have larger ventricles and could generate significantly greater maximum cardiac power output per kilogram body mass than could immature males or females and this enhanced cardiac performance was attributable to delivery of greater cardiac outputs and an increased ability of the heart to work against higher output pressures.
