Moreover, we characterize seasonal variability in range use and ask...

... range, and the Brownian bridge movement model (BBMM) to estimate overall and seasonal home range of the female aye-aye from November 2014 to October 2017. We used Wilcoxon signed-rank tests to determine whether there were significant differences in home range sizes between seasons across years...

..., calculating the home range size for each individual. Results showed that male aye-ayes spent most of their time feeding and travelling. Their feeding time primarily focussed on larvae and adult insects from various substrates, and to a lesser extent Canarium spp. seeds. Home range sizes of the 2 males varied...

...% of the population while the subadults, juveniles and infants comprised 27.3, 12.1 and 6.1%, respectively. Each family group's home range was 0.31-0.51 km 2 . Of the 7 localities, only 1 had more than 1 family group. Habitat destruction and diverse threats to the hoolock gibbon in this area are examined...

...Carolina Gómez-Posada; Jorge Mario Londoño We evaluated population density, group structure and home range of red howler monkeys in a bamboo forest fragment in the Cordillera Central mountain range of Colombia. We estimated a density of 377.7 individuals/km 2 , which is a higher density than...

...Dayong Li; Baoping Ren; Baoguo Li; Ming Li The Yunnan snub-nosed monkey (Rhinopithecus bieti) is characterized by a larger home range and group size than other colobine species. We investigated variations in home range size of a free-ranging group of R. bieti from 1998 to 2007 in the Baimaxueshan...

...Sarah A. Boyle; Waldete C. Lourenço; Lívia R. da Silva; Andrew T. Smith Accurate estimates of a primate’s home range are important, yet methods vary greatly. This paper examines the accuracy of minimum convex polygon (MCP), adaptive kernel (AK) and fixed kernel (FK) estimators by comparing home...

... together. We were able to show that the association rate was higher than would be expected on the basis of chance encounters alone by comparing the observed data with a null model known as Waser’s gas model. The two study groups had almost identical home ranges and hardly ever associated with conspecific...

However, few marks were deposited at the periphery of the area of overlap. Instead, the majority of the marks were in a narrow band within the area of overlap that coincided...

...Hans Sigg; Alexander Stolba Band I at Cone Rock used a home range of 28 km2, which overlapped with the ranges of seven other Hamadryas bands. The utilization pattern of a home range area depended on the habitat type, the distance from the sleeping cliff, and the frequency of visits in that area...

... a male’s knowledge of a potential new home. Extensive overlap in home ranges may facilitate this process. An important result of migration in L. catta is the avoidance of inbreeding in a species whose females form stable groups over long periods of time and do not breed out of their troop. 11 9 2008...

...Patricia C. Wright Findings are presented from a 9-week field study on Aotus trivirgatus in continuous primary, tropical forest in Peru. One group of 2 adults and 2 juveniles utilized the same lodge area in the center of a home range of 3.1 ha for the duration of the study. The group utilized...

We argue that regular subgrouping of the larger focal group and different habitat quality countervailed inter-group variations. Differences from other study sites, however, are not completely explained by current models...
