Summary: The study investigated how tail regeneration affects digestive efficiency, finding that lizards in high predation environments regenerate faster with increased protein digestion rates, while food shortage on islands inhibits the process.

Summary: The study reveals that urbanization impacts the morphological characteristics and tail loss rates of lizards, with more pronounced differences in predation risk between sexes and morphological characteristics between sexes and habitats. The adaptations to urban environments are influenced by multiple selection pressures and associated fitness costs, rather than being solely driven by a single factor such as predation risk.

Summary: The study found that in large lizards, a red tail may increase the chances of being detected by visually oriented predators (such as birds), but not all predators show a preference for conspicuous tails, and tails may not always be the primary target for attacks compared to bodies/heads.

Summary: Tail bifurcation in lizards is caused by anomalous regeneration after tail autotomy. Recent review shows that social media contributes to nearly half of the records, with limited representation from Liolaemidae family. The low incidence of tail bifurcation in Liolaemus might be a real biological phenomenon or a sampling artifact.

Summary: Tail length contributes to increased step length, tail motion ranges increase with relative tail length, and tail deflection ranges increase with relative speed.

Summary: Long-term study of cloacal microbiomes of wild Sceloporus virgatus revealed that microbiome diversity varies with season, sex, body size, and reproductive state independently of each other.

Summary: In order to increase the final running speeds of endangered lizards, we conducted a series of daily running training experiments. The results showed that these training significantly increased the running speeds of the experimental lizards.

Summary: This study examines how fishes optimize energetic expenditure during swimming by controlling tail-beat kinematics. The research identifies that fishes use combinations of tail-beat frequency and amplitude to minimize cost of transport, explaining their swimming strategies and speed control. The findings suggest potential applications in aquatic organisms and bioinspired robotics using undulatory propulsion.

Summary: The study found that male rock lizards with improved nutritional status adopted a more cautious and less costly mating strategy, resulting in siring fewer offspring, but potentially increasing longevity and expected total reproductive success in the future.

Summary: The differences in aerobic performance between sexes are expected in humans due to sexual dimorphisms, but this is not the case in other species. Studies on both human and animal athletic performance provide valuable insights into physiological questions and drive novel research.

Summary: Research suggests that the shape and direction of natural and sexual selection may differ between urban and natural populations of Anolis lizards. Suburban populations of A. homolechis exhibited larger body size, better body condition, more frequent caudal autotomy, and greater sexual dimorphism compared to forest populations. There was also a significant excess of males in suburban habitats and during the non-reproductive season.

Summary: In this article, an untethered robotic fish with multiple flexible joints is proposed to achieve high performance and low Cost of Transport (COT) by taking advantage of the passive bending and energy storage properties of flexible materials. A compact flexible tail with a simple and efficient structure, combining rigid links and flexible materials, is proposed. The pseudo-rigid body theory is applied to analyze the deformation of passive joints, and an optimization method by adjusting the phase differences of the passive joints is used to obtain high aquatic performance.

Summary: In this study, behavioral and chemical data were combined to examine the role of olfactory communication in the advertisement of species, sex, and reproductive status in cotton-top tamarins and bearded emperor tamarins. Females marked more frequently than males, and reproductive individuals more than non-reproductive ones. The anogenital gland was predominantly used for scent-marking, followed by the suprapubic gland.

Summary: This study examined the association between factors influencing female sex hormones and the efficacy of DMARDs in patients with RA. It was found that perimenopausal women were less likely to achieve remission, while the use of exogenous sex hormones was associated with higher remission rates in female RA patients.

Summary: The research found that female Arma custos have a higher tendency for egg cannibalism than males. Egg cannibalism varies not only with the developmental stage of the eggs and nymphs, but also with the sex and reproductive status of female A. custos. These findings contribute to a better understanding of the evolutionary relationships in egg cannibalism by A. custos and help improve the efficiency of mass rearing and biological control systems utilizing A. custos.
