Cover: Air-breathing fishes are generally associated with tropical environments,Êbut the Alaska blackfish Dallia pectoralis contradicts this common conception by inhabiting waters that are ice-covered in winter, although it enters warm and hypoxic waters in the summer to forage and reproduce. Lefevre, Stecyk and colleagues (pp. 4387−4398) use bimodal intermittent-closed respirometry to investigate the influence of varying environmental conditions on air breathing in an attempt to shed light on the selective pressures that maintain the air-breathing ability. Their results show that hypoxia is the main drive for air breathing, even at cold temperatures, whereas increased temperature in itself does not stimulate air breathing.

Using the reactive scope model to redefine social stress in fishes
In their Review, Katie Gilmour and colleagues redefine the ambiguous concept of social stress by using the reactive scope model as a framework to explain the divergent physiological phenotypes of dominant and subordinate fishes.
JEB grants to support junior faculty

Thirteen-lined ground squirrels survive extraordinarily low blood oxygen
Brynne Duffy and colleagues reveal that thirteen-lined ground squirrels are true hypoxia champions surviving extreme low blood oxygen, down to just 34% oxygen, when they emerge briefly from hibernation.
The Company of Biologists Workshops
For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Fast & Fair peer review
Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
