Summary: Home range is an important measure for understanding animal space use. However, previous macroecological studies have not fully considered the environmental context and intraspecific variation. This study introduces HomeRange, a global database with 75,611 home-range values of 960 mammal species, including terrestrial, aquatic, and aerial species. The database provides detailed information on species traits and methodological aspects.

Summary: Data on African sand cats was collected in Morocco between 2015 and 2019. 47 sand cats were observed, 41 were captured, and 22 were tracked with VHF radio-collars. Average home-range sizes were calculated for females and males, with ranges varying between 274.6 and 319.3 square kilometers. The study suggests that sand cats are tolerant of each other and likely non-territorial, but more research is needed to understand their ecology, social organization, and mating patterns.

Summary: Home range size estimation is crucial for conservation strategies and understanding animal behavior and spatial ecology. This study analyzed home range variations and estimation methods on Chinese gorals living in a cliff landscape using GPS tracking data. The recommended alpha-LoCoH model more accurately reflected animal locations within the steep cliff habitat, and more GPS tracking of animals is needed for validity in rugged habitats. This study is the first to conduct home-range GPS tracking of Chinese gorals in their northern distribution range, providing valuable information for conservation strategies.

Summary: Interspecific aggression has important fitness consequences and can lead to declines in native species during species invasions. This study investigated the immediate behavioural consequences of interactions between native green anole lizards and invasive Cuban brown anoles. The results showed that green anoles exhibited smaller home ranges and higher perch heights after the invasion, but these changes were not caused by aggression from the brown anole invaders. Both species preferred to interact with conspecifics, and escalated aggressive behaviours between the two species were rare. The findings suggest that high population densities of brown anoles, rather than direct competition, may be driving the displacement of green anoles across the brown anole's invasive range.

Summary: Ecological (isotopic) niche refers to a surface in a two-dimensional space reflecting stable isotopes in animal tissues. Carbon and nitrogen stable isotope ratios provide valuable information about trophic ecology, resource use, and population dynamics. The use of minimum convex polygons is advocated as a relevant tool for assessing isotopic niche size, overlap, and characteristics.

Summary: A new method called OAFM is proposed for ellipse packing, allowing particle rotation and movement to generate dense ellipse packing with specific size, aspect ratio, and orientation. The method uses multicircles to approximate ellipses and constructs initial cells which are then merged to create statistically equivalent convex polygons matching the obtained ellipses in size, aspect ratio, orientation, and location. Three examples demonstrate the effectiveness of the method in generating convex polygons that satisfy a spatial arrangement.

Summary: In the montane forest of Nyungwe National Park, Rwanda, we investigated the factors influencing chimpanzee party size, finding that the presence of estrous females had the strongest impact. Interestingly, the availability and distribution of important fruits did not directly affect party size, but influenced the presence of estrous females. This suggests that fruit distribution could be the ecological precondition attracting estrous females, the main driver behind larger party sizes.

Summary: Our study found that while larger groups of Virunga mountain gorillas showed significantly increased group spread, there was still an increase in individual travel; contrary to expectations, group travel decreased with size for most groups, but individual travel increased with size; limited evidence was found for patch depletion that would cause the second mechanism of scramble competition.

Summary: This study found that dominant individuals in non-human primate species who were more tolerant tend to vocalize at a higher rate, while despotic species have a larger repertoire of hierarchy-related vocalizations. This suggests that primate signals evolve in relation to the nature of interactions that characterize individuals' social relationships.

Summary: This study on wild chimpanzees' gut microbiomes reveals a high degree of regional specificity in microbiome composition, linked to host genetics, available plant foods, and potentially cultural differences in diet influenced by tool use. Genetic differences primarily shaped community composition at large scales, while vegetation and potentially tool use were key factors driving within-region differences.

Summary: Investment in social interaction and affiliative behaviour varies among and within species in response to sex-specific dispersal patterns and local environmental conditions. This study examines association patterns in a high-elevation population of chimpanzees and finds that resource distribution and the presence of oestrous females impact gregariousness differently for males and females.

Summary: By comparing the social organization (solitary, pair-living, and group-living) and longevity of nearly 1000 mammalian species, it is found that group-living species generally live longer than solitary species. Furthermore, a comparative transcriptomic analysis of 94 mammalian species identifies 31 genes, hormones, and immunity-related pathways associated with social organization and longevity, highlighting the molecular basis of the influence of social organization on longevity.

Summary: Risk taking is more common in males, and it serves as a signal for prospective mates. Previous research has shown that male risk takers are more attractive for short-term flings, but the influence of environmental and socioeconomic context on female preferences has been overlooked. In a survey with 1304 females from 47 countries, we found that females with a bisexual orientation and higher risk proneness had stronger preferences for physical risk takers. Self-reported health and country-level health moderated the preference for high risk takers as short-term mates. The risk of COVID-19 did not influence avoidance of risk takers.

Summary: Recently, there has been a significant contraction in the distribution ranges of canids in Sichuan Province, China, with factors such as altitude, temperature, land use, and human population density playing key roles. Canid contraction rates in nature reserves were lower than in other types of protected and non-protected areas. Although the Chinese government has upgraded the protection level of canid species and established more national parks, it is crucial to monitor anthropogenic disturbance, implement compensation schemes for human-wildlife conflict, and enhance public wildlife conservation education.

Summary: The study conducted a field experiment in rural Australia to investigate ingroup favoritism in a naturalistic helping task. The results showed no evidence of ingroup bias, with only the socioeconomic prosperity of towns significantly affecting the likelihood of letters being returned. This lack of discrimination can be explained by the material security hypothesis, which suggests that institutions ensuring material security lessen the need for investments in local community members to meet basic needs.
