Cover: A still taken from a digital animation of Maori design from Whanganui driven by recordings of calls of the Tieke (north island saddleback, Philesturnus rufusater) recorded at Tarapuruhi Bushy Park ecosanctuary. The work is a collaboration between a Whanganui artist and scientist as they engage in a series of works that challenge our dichotomous framings of art and science, and by extension of science and Indigenous knowledges. Hird et al. (jeb245302) discuss the experiences of Indigenous scientists working within settler-colonial research institutions, specifically the tensions in addressing ongoing exclusion of their knowledge traditions, and invite settler-scholars to challenge the hidden assumptions of knowledge superiority.

PERSPECTIVE
Moving beyond ontological (worldview) supremacy: Indigenous insights and a recovery guide for settler-colonial scientists
Summary: Indigenous scientists working within settler-colonial research institutions experience tensions in addressing ongoing exclusion of their knowledge traditions. We invite settler-scholars to challenge the hidden assumptions of knowledge superiority.
COMMENTARY
Ectotherm heat tolerance and the microbiome: current understanding, future directions and potential applications
Summary: Microbiomes can influence the thermal tolerance of ectothermic animals; however, many questions remain regarding the role that microbes play in the thermal ecology and evolution of their hosts.
REVIEW
The dynamics behind diversity in suboscine songs
Summary: This Review highlights how biomechanical adaptations in different suboscine species allow them to generate a rich variety of acoustic features in their songs.
RESEARCH ARTICLES
Emersion and recovery alter oxygen consumption, ammonia and urea excretion, and oxidative stress parameters, but not diffusive water exchange or transepithelial potential in the green crab (Carcinus maenas)
Summary: During 14 h air exposure, oxidative stress occurs in the green crab, oxygen consumption is maintained, and ammonia and urea excretion are greatly suppressed, with large increases in all rates during aquatic recovery.
A phenomics approach reveals interspecific differences in integrated developmental responses to chronic elevated temperatures
Summary: Complex, ontogenetic differences in temperature-induced responses of the phenome of encapsulated gastropod embryos are underpinned by altered physiology and behaviour, and thermal plasticity in developmental event timings.
Muscle force–length dynamics during walking over obstacles indicates delayed recovery and a shift towards more ‘strut-like’ function in birds with proprioceptive deficit
Summary: In vivo muscle recordings during walking in obstacle terrain reveal that a proprioceptive deficit is associated with a shift towards ‘strut-like’ isometric muscle function and delayed obstacle recovery in guinea fowl.
Host species differences in the thermal mismatch of host–parasitoid interactions
High temperatures reveal differences between two host species in their ability to recover at least parts of their developmental pathways that are typically disrupted by parasitism.
Sex-specific transgenerational plasticity: developmental temperatures of mothers and fathers have different effects on sons and daughters
Summary: The effects of temperature variation on biological processes depend on the sex of parents and offspring, increasing the complexity for forecasting environmental impacts.
Temperature and the microbial environment alter brain morphology in a larval amphibian
Summary: The thermal and microbial environment in which a tadpole develops shapes its gut microbiota and neurodevelopment, providing some of the first evidence for a microbiota–gut–brain axis in an amphibian.
Ventricular fold oscillations lower the vocal pitch in rhesus macaques
Summary: Ex vivo and in vivo experiments indicate an additional vocal repertory in rhesus macaques, in which the ventricular folds co-oscillate with the vocal folds to significantly lower the fundamental frequency.
Ciliated sensory neurons can regenerate axons after complete axon removal
Drosophila larvae ciliated lch1 neurons can regenerate axons following complete axon removal, suggesting the presence of a sensory cilium does not limit the capacity of neurons to respond to axon injury.
Muscle function during cross-country skiing at different speed and incline conditions
Muscle and joint behaviour in the lower leg are uncoupled during cross-country skiing at different speeds and inclines; while the muscle–tendon unit undergoes a stretch–shortening cycle during propulsion, fascicles shorten.
Displacement experiments provide evidence for path integration in Drosophila
Summary: Experiments that exclude the confounding effect of pheromones show that Drosophila remember the location of an optogenetically delivered reward.
Visual environment of rearing sites affects larval response to perceived risk in poison frogs
Summary: The visual environment of rearing sites used by poison frogs affects tadpole responses to risky visual stimuli in novel contexts.
Linking muscle mechanics to the metabolic cost of human hopping
Summary: Direct measurement of activation and work requirements of lower-limb musculature and whole-body metabolic energy requirements across a wide variety of human hopping conditions to guide biomechanical models of energy expenditure.
Two feedback mechanisms involved in the control of leaf fragment size in leaf-cutting ants
Plasticity in fragment size determination in leaf-cutting ants is controlled by sensory information provided by both the leg contact with the leaf edge and the lateral bending of the head.
ECR SPOTLIGHTS
Announcing the 2024 JEB Outstanding Paper Prize shortlist and winner
Every year JEB celebrates early-career researchers through the Outstanding Paper Prize. We recognise the shortlisted ECRS that contributed to 11 remarkable studies published in 2024 and congratulate the winner, Elise Laetz, from University of Groningen. See how else JEB supports and promotes ECRs.
Inside the Intergovernmental Panel on Climate Change with Hans-Otto Pörtner
During the past two decades, Hans-Otto Pörtner has steered climate change policy as a co-Chair of IPCC Working Group II. He tells us about the experience in this Perspective.
Photosynthesis turns symbiotic sea anemone's tentacles toward sun
Snakelocks sea anemones point their tentacles, packed with symbiotic algae, toward the sun so their lodgers can photosynthesize, and now Vengamanaidu Modepalli & colleagues have discovered that photosynthesis by the algae guides their host's tentacles towards the sun.
