Cover: Spiderlings just before emerging from the egg sac. Agelena labyrinthica females lay their egg sacs in late summer. After 20 days of incubation, the eggs hatch in the cocoon. After a week, spiderlings moult for the first time, then enter a winter diapause until early spring, when they emerge from the egg sac and remain gregarious for a few days before they disperse and become aggressive. Mauduit and Jeanson (jeb245387 ) have demonstrated that tolerance in aggressive spiderlings can be restored when exposed to siblings after the first moult outside the egg sac.

REVIEWS
Two decades of research on anoxia tolerance – mitochondria, -omics and physiological diversity
Summary: Two decades of research on anoxia tolerance have highlighted the role of mitochondria in this phenomenon and have revealed that tolerance of reoxygenation must also be considered.
Perturbing the muscle work loop paradigm to unravel the neuromechanics of unsteady locomotion
Summary: Recent studies extending physiological work loop techniques to unsteady conditions are organized into top-down and bottom-up approaches, to work towards understanding function from isolated muscle to integrated movement.
How scaling approaches can reveal fundamental principles in physiology and biomechanics
Summary: Body size affects an animal's shape, energy use, movement patterns and ecology. Here, we illustrate how scaling principles can explain how physical limits and evolutionary history can determine form and function.
SHORT COMMUNICATION
Social recapitulation: moulting can restore social tolerance in aggressive spiderlings
Summary: Spiderlings reared in social isolation develop aggressive interactions, but tolerance can be induced if they are exposed to their siblings just after moulting.
METHODS & TECHNIQUES
Measurement of voluntary bite forces in large carnivores using a semi-automated reward-driven system
Summary: Maximum bite forces of large mammals can be measured voluntarily using an automated system.
RESEARCH ARTICLES
Responses of the in vitro turtle brain to visual and auditory stimuli during severe hypoxia
Severe hypoxia attenuates the visual, but not auditory responses in a reduced brain preparation from a pond turtle.
A hypothesis for robust polarization vision: an example from the Australian imperial blue butterfly, Jalmenus evagoras
A novel model for robust polarization vision in butterflies based on the alignment of ommatidial arrays, supported by behavioral, spectroscopic and histological evidence from the Australian butterfly Jalmenus evagoras.
Accelerated abdominal lipid depletion from pesticide treatment alters honey bee pollen foraging strategy, but not onset, in worker honey bees
Honey bees exhibit a gradual decline in abdominal lipid that can be accelerated by stress; this pesticide-induced accelerated lipid decline shifts foraging preference to fattier pollen.
Ontogenetic exposure to light influences seabird vulnerability to light pollution
Summary: Exposure to light stimuli during growth increases visual behavioural responses in chicks of a light-impacted seabird species.
Dynamics of horizontal walking and vertical climbing in the Australian green tree frog (Ranoidea caerulea)
Summary: When vertically climbing, tree frogs generate propulsive forces from both the hindlimb and forelimb. They exhibit high mechanical efficiency, with total mechanical power costs only slightly above a theoretical minimum.

Extraordinary creatures: mantis shrimp
In our new Conversation series focusing on extraordinary creatures, Tom Cronin and Sheila Patek tell us about the incredible biology of mantis shrimp, from their complex vision to their powerful striking abilities.
Behaviour as a physiological process
In this Commentary, Shamil Debaere & colleagues argue the case for integration of behaviour into animal physiology, and advocate for behaviour to be considered as a physiological process.
Tiny ring-necked snakes keep warm heads despite their size
Some ectotherms are able to raise the temperature of certain body parts above the temperature of other regions & now Christian Fox and Albert Chung, with undergraduates from the University of Virginia, reveal that the heads of tiny ring-necked snakes can be 2.1C warmer than their tails, even though they are only 20cm long.
