Movement, Seasonal Activity, and Home Range of an Isolated Population ofGlyptemys muhlenbergii, Bog Turtle, in the Southern Appalachians

The activity patterns of a resident population of 15 feral cats (Felis catus L.) on New Zealand farmland were investigated from March 1984 until February 1987 by radiotelemetry. Females could be divided into two separate groups: (1) those denning in barns and (2) those denning in the swamp and willows. Females denning in barns were mainly nocturnal except in spring and summer when rearing kittens. Barn cats moved significantly further between dusk and dawn, except in autumn-winter, than those denning in swamp and willows which were active over 24 h. When not breeding, related females occupied the same barn. In both groups, the home range of female relatives overlapped. Males ranged over all habitats, and dominant adult males moved significantly further and had larger home ranges than other males in all seasons, except in summer when they rested, avoiding hot summer days. Only adult males were active during the day in spring and autumn-winter. The importance of a Zeitgeber in synchronising cat activity with that of the prey is examined. The significance of female den site is discussed in relation to proximity of food, predators, social behaviour and male defence.

AbstractWe describe the behavioral adaptations of a population of Hermann's tortoise to the climate of a northern sector of its range, and to a wooded biotope that is uncommon for the species. The activity, the home range, and the thermal relations along the daily and the yearly cycle are described. In contrast to other populations that have bimodal activity peaking in spring and in autumn, the tortoises in our study area had unimodal seasonal activity that can be related to lower summer temperatures. Home range size, 7.4 ha for females and 4.6 ha for males in our study area, was from three to seven times larger than that of all other populations. The large home range, and the low population density of the tortoises in our study area, may be due to food scarcity in the wooded habitat.

The present work is to highlight the threats being faced by the Egyptian Vultures Neophron percnopterus (Linnaeus, 1758) in its original area including Mathura district. An isolated population of Egyptian Vultures was seen in 2007-08 spread over an area of 20-30 Kilometers home range. Actually, scores of Egyptian vultures were seen airborne gyrating in the skies at low height on the outskirts of Mathura city towards Delhi. Astonishingly, in 2008, another group of 40-50 Egyptian Vultures was seen feeding on 2-3 carcasses of Cattle on left hand side of Agra-Delhi National highway in September, 2008 towards Delhi. However, a visit in April, 2011 revealed a fatal fact, as all these birds of this population were certainly eclipsed in a short span of 3-4 years. Neither the airborne group nor the “Kosi-Kalan” village road side group was traceable. So much so, not a single bird could be sighted. In conclusion, it is boldly inferred over here that Egyptian Vultures are already in the brink of near extinctions as of in 2013, only one bird was traced on Mathura-Agra Highway.DOI: http://dx.doi.org/10.3126/ijls.v8i1.8084

Tupinambis Merianae

AbstractThe activity and space parameters (home range and use of space) for a population of Tupinambis merianae was recorded through 640 h of observation during nine months, and by monitoring 56 marked individuals. There was a significant difference in activity in the periods stipulated in this study throughout the months. Active lizards were not registered before 7:30 a.m., nor after 6:00 p.m. The greatest level of activity by the individuals occurred during November and December. Fluctuations in the population size and in the activity of the different age classes were recorded throughout the studied months. We recorded the minimum home-range of three males and two females, which varied from 0.05 to 26.44 ha. We also observed agonistic interactions. The utilization area of the animals did not vary during the studied months, but it was possible to observe gregarious behavior in spatial use. The highest daily activity occurred at the hours of higher temperatures. The positive correlation between seasonal activity and the maximum temperature (air and substrate) showed a unimodal distribution and was identical to the records from a tropical area (southeastern Brazil). It is possible that temperature is not the only environmental variable/factor that influences the seasonal activity cycle of the species. Although teiids are not considered territorial, some of our results could suggest territoriality in the studied population.

Context Understanding habitat selection is important for determining conservation and management strategies for endangered species. The Carolina northern flying squirrel (CNFS; Glaucomys sabrinus coloratus) is an endangered subspecies found in the high-elevation montane forests of the southern Appalachians, USA. The primary use of nest boxes to monitor CNFS has provided biased information on habitat use for this subspecies, as nest boxes are typically placed in suitable denning habitat. Aims We conducted a radio-telemetry study on CNFS to determine home range, den site selection and habitat use at multiple spatial scales. Methods We radio-collared 21 CNFS in 2012 and 2014–15. We tracked squirrels to diurnal den sites and during night-time activity. Key results The MCP (minimum convex polygon) home range at 95% for males was 5.2±1.2ha and for females was 4.0±0.7. The BRB (biased random bridge) home range at 95% for males was 10.8±3.8ha and for females was 8.3±2.1. Den site (n=81) selection occurred more frequently in montane conifer dominate forests (81.4%) vs northern hardwood forests or conifer–northern hardwood forests (9.9% and 8.7%, respectively). We assessed habitat selection using Euclidean distance-based analysis at the 2nd order and 3rd order scale. We found that squirrels were non-randomly selecting for habitat at both 2nd and 3rd order scales. Conclusions At both spatial scales, CNFS preferentially selected for montane conifer forests more than expected based on availability on the landscape. Squirrels selected neither for nor against northern hardwood forests, regardless of availability on the landscape. Additionally, CNFS denned in montane conifer forests more than other habitat types. Implications Our results highlight the importance of montane conifer to CNFS in the southern Appalachians. Management and restoration activities that increase the quality, connectivity and extent of this naturally rare forest type may be important for long-term conservation of this subspecies, especially with the impending threat of anthropogenic climate change.
