Summary: Wings and fins bend remarkably similarly among animals that fly and swim. Here, we review these patterns, describe their mechanistic benefits and propose a path forward for their study.
The mechanistic basis and adaptive significance of cross-tolerance: a ‘pre-adaptation’ to a changing world?
Summary: Although stress exposure is typically detrimental, here, we highlight protective interactions where exposure to mild stress can increase an organism's resilience to a different stressor – a phenomenon termed ‘cross-protection’.
Summary: We recently developed a new theory to explain the evolutionary origin of metabolic scaling. Here, we present an overview of our approach and a critique of its limitations.
In a marine teleost, the significance of oxygen supply for acute thermal tolerance depends upon the context and the endpoint used
Summary: In the European seabass, cardiorespiratory capacity to supply oxygen for metabolism is significant for tolerance of thermal ramping if the endpoint is fatigue from aerobic exercise, but not if the endpoint is loss of equilibrium under resting conditions.
Divergence in cell cycle progression is associated with shifted phenology in a multivoltine moth: the European corn borer, Ostrinia nubilalis
Summary: Regulation of cell cycle progression rates drives differences in larval diapause termination, and adult emergence timing, between early- and late-emerging European corn borer strains.
Summary: The temperature for optimal righting performance of an African whelk (Trochia cingulata) shifts with acclimation temperature but, contrary to previous studies, its upper thermal tolerance increases with temperature and acidification.
Highlighted Article: An arctic arthropod adjusts its thermal tolerances to microenvironmental fluctuations within a time scale of minutes–hours. The gene expression modulating physiology occurs at much different temperatures in the field than laboratory.
Impacts of ocean acidification and warming on post-larval growth and metabolism in two populations of the great scallop (Pecten maximus)
Summary: Juvenile scallops from France and Norway differ in their response to warming and acidification: French scallops show more physiological plasticity, adjusting their proteome and metabolism to maintain growth.
A sensation for inflation: initial swim bladder inflation in larval zebrafish is mediated by the mechanosensory lateral line
Summary: Larval zebrafish use their lateral line to sense the air–water interface and regulate initial swim bladder inflation to achieve neutral buoyancy.
Highlighted Article: Under brighter illumination, fewer glow-worm males reach a female-mimicking LED in a Y-maze, taking longer to do so, partly because they retract their head beneath their head-shield for longer.
Summary: The evolution of mammalian red blood cell features, above all size and haemoglobin–oxygen affinity, has interesting relevance to concepts such as biological constraint, preadaptation and adaptive selection.
A diminutive snake species can maintain regional heterothermy in both homogeneous and heterogeneous thermal environments
Summary: Diminutive snakes can maintain regional heterothermy despite elongate shapes in both homogeneous and heterogeneous thermal environments.
