Summary: Research indicates that amphibians in England and Wales commonly exhibit arboreal behavior, with common toads being found in hazel dormouse nest boxes, tree cavities, and even bird nests. However, there are fewer records of frogs or newts engaging in similar behavior.

Summary: Research on the morphology of the inner ear's semicircular ducts suggests that endothermy evolved abruptly during the Late Triassic period, correlated with a sharp increase in body temperature and an expansion of aerobic and anaerobic capacities.

Summary: This study reports on a Mesozoic mammal, Filikomys primaevus, with evidence suggesting multigenerational, group-nesting, and burrowing behavior, representing the first example of social behavior in Mesozoic mammals. Sociality in mammals may be an evolutionarily labile trait that has arisen repeatedly during mammalian evolution.

Summary: This study examines the early vocal development of three species (common marmoset monkeys, Egyptian fruit bats, and humans) and finds that their acoustic features can undergo sudden transitions, consistent with the concept of punctuated equilibria. By modeling different developmental landscapes, the study suggests that the transitions can be described as a shift in the balance of two vocalization landscapes. The importance of energy expenditure and information transmission in vocal development is supported by experiments manipulating these factors in marmoset monkeys.

Summary: This study reveals the regulatory divergence of gene expression in response to behavioral context, and how this dynamic regulatory divergence between species contributes to behavioral evolution. The findings show that burrowing behavior-induced cis-regulatory changes are associated with species-level differential expression and allele-specific expression.

Summary: Animals in nature rarely use their maximum performance abilities, possibly due to context-dependent differences in performance motivation. This study manipulates the levels of the biogenic amine octopamine (OA) and tests its role in driving male house crickets' motivation to express maximum bite force. The results show that OA is an important mediator of performance in insects and plays a significant role in performance motivation.

Summary: Chronic exposure to titanium dioxide nanoparticles (TiO2 NPs) impairs locomotor behavior in Drosophila, as evidenced by reduced crawling distance in larvae and movement distance in adult males. This impairment is associated with altered morphology of neuromuscular junctions (NMJs) and differential gene expression related to NMJ development. These findings demonstrate that TiO2 NPs exposure damages NMJ morphology and disrupts locomotor behavior in Drosophila.

Summary: Zinc tungstate (ZnW04) shows multiple surface terminations under certain thermodynamic equilibrium conditions, with the W2O4 - Zn8W6O36 termination exhibiting stronger light absorption and delocalized surface states within the band gap.

Summary: This study investigates the different mechanisms species have evolved to combat oxidative stress within cells, particularly focusing on the occurrence of ferroptosis. Through phylogenetic analysis, it was found that Arabidopsis GPXs are more closely related to mammalian GPX4 than other mammalian GPXs. Ectopic expression of Arabidopsis GPXs in ferroptosis-sensitive mouse fibroblasts provided protection against ferroptosis induction, suggesting a potential for experimental substitution.

Summary: The study reveals that under the influence of sublethal concentrations of marginolactone azalomycin F released by Streptomyces, the green alga Chlamydomonas reinhardtii forms a protective multicellular structure called gloeocapsoid. This structure helps the alga survive in alkaline pH and otherwise lethal concentrations of azalomycin F, indicating a cross-kingdom competition with ecological relevance.

Summary: Researchers have discovered a fossilized larynx of a dinosaur called Pinacosaurus grangeri, suggesting that non-avian dinosaurs may have had bird-like vocalization. This is the first laryngeal fossil from the Cretaceous dinosaur, providing insights into the vocal evolution in non-avian dinosaurs towards birds.

Summary: We studied the impact of dietary differences in mammalian omnivores on macroevolutionary and macroecological trends. It was found that most omnivores consume only invertebrate prey and non-fibrous plants, and omnivores that consume invertebrate prey are on average smaller in size. The results suggest that prey type is correlated with body mass, evolutionary history, and diet-related evolutionary transition rates, highlighting the importance of considering the ecological variety in omnivore diets in future research.

Summary: In this study, the surface ultra-structural topography, nanotribology, and chemical compositions of mammal species with different dietary habits were characterized using scanning probe microscopy, depth sensing, and spectromicroscopy. It was found that enamel with greater surface hardness or thickness exhibited a more salient gradient feature from the tooth surface to the dentino-enamel junction (DEJ) that corresponds to the in situ phosphate-to-amide ratio. This gradient feature of enamel covering softer dentine determines the robust physical property of this unique biomaterial, allowing it to dissipate stress and prevent mechanical failure. The evolution of mammalian dentition's biochemical composition and biomechanical properties is related to variations in the oral processing of different food materials.

Summary: Co-firing ammonia promotes devolatilization of coal and release of volatiles, affects the conversion of volatiles into soot, and changes the flame radiation properties. In fuel-lean conditions, co-firing ammonia increases the number density and size of soot particles, while in fuel-rich conditions, they decrease.
