Issues

Highlighted Article: Although olfactory systems are essential for chemosensing environmental and social cues, sensory perception and its deprivation can also affect oogenesis and fecundity in Drosophila melanogaster.

Summary: Transfer learning is an effective tool for leveraging deep learning in acceleration-based behavior identification for wildlife monitoring, enabling existing models to be adapted to the species under study.

Highlighted Article: The material properties of macrostomate snake skin vary longitudinally and following feeding, with particularly compliant anterior-most regions of skin, likely representing a derived trait facilitating large prey ingestion.

Summary: The thermal biology of Cryptomys hottentotus hottentotus does not vary along an aridity gradient. Instead, osmoregulatory traits appear to provide the basis for extreme arid adaptation, with implications for conservation of subterranean species under future climate scenarios.

Summary: Nociceptive responses in Manduca sexta reveal that stimulus location determines whether a strike or withdrawal movement is elicited. While both behaviors involve sequential muscle activation, they recruit different longitudinal muscle groups specific to each response.

Summary: In alligators, limb bone strains increase with larger body sizes when similar postures are adopted across individuals of different sizes, while axial strains predominate over off-axial strains with the use of a more erect posture.

Summary: Sublethal desiccation exposure and short-term starvation do not significantly affect heat tolerance in honey bees and sweat bees.

Summary: Manipulation of muscle timing in behaving hawkmoths to investigate how individual muscles contribute to flight shows precise timing of single muscles does not produce precise turns, highlighting the importance of coordination across the entire motor program.

Summary: Primates must solve special challenges of collisional costs in the trees. Squirrel monkeys use compliant limbs to move their bodies like a ‘skipping stone’ and manage costs.

Summary: A comparative analysis of locomotor behavior in ants transporting food internally or externally reveals that locomotion could be biomechanically more efficient when transporting food internally than externally.

Summary: The dynamics, biomechanical constraints and musculotendinous coordination strategies during the sit-to-stand/walk transitions for a large bipedal bird – the emu – inform morphology, evolution and potential robotic applications.

Summary: When a grasshopper jumps from a springy platform, the physical characteristics of the animal and platform determine the energy efficiency of the jump.

Summary: Desert-adapted cactus mice fed a lower-fat diet show altered gene expression relating to mitochondrial function, immune function and circadian rhythm, highlighting the complex interplay between diet, physiological processes and environmental adaptation.

Summary: In under half a second, stick insect hatchlings swiftly adjust their leg posture, initiating controlled gliding from a fall.

Highlighted Article: Incubation temperature and prenatal corticosterone exposure have independent sustained effects, but not interactive effects, on morphological and physiological traits in the delicate skink.

Summary: Glycoprotein hormone GPA2/GPB5 signaling is crucial for regulating diuresis in Rhodnius prolixus, influencing fluid secretion and the interplay of diuretic and antidiuretic hormones during blood feeding.
