Issues

Summary: Evolutionary genetic studies provide insights into thermal physiology, but suggest that adaptations to temperature are only partially predictable in invertebrates. This may limit some models predicting future responses to temperature.

Summary: An integrative framework combining insights from thermal death time (TDT) curves and physiological reaction norms precisely captures Pinctada margaritifera thermal performance and tolerance landscape.

Highlighted Article: Development of WildPose: a portable, long-range 3D motion capture system, combining LiDAR and zoom-lens cameras, enabling precise, non-intrusive wildlife observation and advancing ecological and biomechanical research.

Summary: Long-train electrical stimulation of the pallial surface produces distinct orobranchial kinematic patterns that represent predatory behaviour in teleost fish.

Highlighted Article: The pleiotropic actions of allatostatin-C peptides are not well known. Neuroanatomical investigations, coupled with receptor de-orphaning and measurement of circulating titers, suggest previously unreported roles in the ecdysis program.

Highlighted Article: The social environment, but not energetic optimal swimming speed, affects preferred swimming speed in a marine generalist fish.

Summary: The temporal dynamics of thermal tolerance plasticity following thermal acclimation in Enchytraeus albidus depends on both culture and acclimation temperatures, and is linked to changes in phospholipid fatty acid composition.

Summary: Thermoregulatory costs in Ctenomys talarum may limit the energy available for immunity, leading to different strategies to cope with infection during exposure to varying ambient temperature.

Summary: Four alternatively spliced PKG1 isoforms as well as PKG2 sequences were identified in crustaceans. In vitro YO assays with MIH±PKG inhibitors revealed PKG1 and PKG2 had opposing effects on MIH-regulated ecdysteroidogenesis.

Highlighted Article: The metabolomic profiles of 43 Drosophila flies are correlated with climatic variables of their habitats and with their cold tolerance and ability to improve it in response to seasonal cold acclimation.

Summary: Temperature-sensitive transient receptor potential (TRP) channels of the elephant shark, a cartilaginous fish, show unique heat and cold sensitivities, shedding light on vertebrate thermosensory evolution.

Highlighted Article: Fish raised in structurally complex environments develop larger otoliths without altering their auditory sensitivity, supporting that the sagitta also plays a role in vestibular function.

Summary: Ghrelin inhibits water intake without vasopressor effect in conscious eels; thus, the action is unlikely mediated by ANP secretion. Additionally, it is likely mediated through different receptors from GHS-R1a.

Summary: Virtual reality reveals that ants rely on a heuristic to trigger visual exploration in an unfamiliar scene. Simultaneous presence of vertical and horizontal edges is necessary and sufficient for ants to produce lateral oscillations and scan the scene.

Summary: Salmon that initiate hypoxic bradycardia cannot increase heart rate when warmed. This response is mediated by cholinergic tone and protects heart function.

Summary: Canaries fed a diet high in lipids show more severe disease outcomes than those fed a high-protein diet, with important implications for human and wildlife disease transmission.

Summary: Investigation of the relationship between muscle strain and posture in corn snakes in vivo using fluoromicrometry reveals a strong, predominately linear relationship between muscle shortening and vertebral column curvature, as predicted by mathematical modeling.
