“…During the course of our study a parallel study on the effect of supplemental feeding on the center of activity and the diet of these maned wolves was being undertaken. This study showed that although the wolves did utilize the supplemental food on a daily basis (approximately 30% of their daily intake), they also hunted vertebrate and invertebrate prey and consumed plants [Silva and Talamoni, 2004]. Furthermore, a study of their ecology and habitat selection showed many parameters, such as home range size, to be in accordance with published values for wild maned wolves [see Coelho et al, 2008].…”

“…It may of course be that the male was performing other important roles necessary for the survival of offspring such as territorial marking. In the parallel study of Silva and Talamoni [2004] the maned wolves deposited many feces close to the sanctuary where the supplemental feeding was taking place. Dietz, based on his studies of wild maned wolves in Brazil (1984Brazil ( , 1985, suggests that individuals place feces to mark their territory.…”

“…In the center of the reserve is a hotel where supplemental feeding (approximately 2 kg of meat per day) of the maned wolves occurred on a nightly basis between 19:00 and 22:00 hr. The reserve and the supplemental feeding have been described in detail by Silva and Talamoni [2004]. Our study was conducted from June 2001 until August 2001 for a period of 65 days.…”

In many species of canids the male's role in reproduction extends to providing extensive or some parental care to his offspring. Maned wolves are a monogamous canid species whose males have been observed providing parental care to their offspring in captivity, but no field observations exist. We observed a wild pair of maned wolves at their nest site in a period soon after the female had given birth for a total period of 65 days. We made five observation sessions with an average of 3-4 days each separated by approximately 2 weeks. Direct visual observations of maned wolves were made each 30 min during the hours of darkness (17:00-07:00) using night-vision binoculars and confirmed by VHF radiotelemetry. During observations we recorded the location of the male and the female in relation to the nest (i.e., in the nest, nearby or long way from the nest). The results showed that the female spent more than 60.44% of her time in or near the nest. The male spent 28.90% of his time in or near the nest. There was a positive significant correlation between the female and the male in terms of the amount of time spent in or near the nest (P<0.01). The maned wolves showed a strong temporal variation in time spent in or near the nest. In conclusion, our data show that wild male maned wolves--probably--provide parental care through provision of food to their female and presumed offspring rather than "babysitting."

Non‐territorial Macaques Can Range Like Territorial Gibbons When Partially Provisioned With Food

et al. 2015

Human food supplementation can affect components of animal socioecology by altering the abundance and distribution of available food. We studied the effect of food supplementation by comparing the ranging patterns and intergroup interactions of two groups of northern pigtailed macaques (Macaca leonina), a non-territorial primate species. One group was partially reliant on food provisioning, whereas the other group foraged wild food. We also compared the macaques' movement with that of a group of white-handed gibbons (Hylobates lar), a territorial species inhabiting the same site. Home range, core area, and daily path lengths were significantly smaller for the semi-provisioned group than for the wild-feeding group. In contrast to wild-feeding macaques, supplemented macaques showed higher fidelity to home range, core area, and particularly to the region where human food was most accessible and abundant. The relationship of daily path length and home range indicated a low defendability index for wild-feeding macaques; the higher index for the semi-provisioned group was consistent with the territorial pattern found in gibbons. Semi-provisioned macaques showed further traits of territoriality with aggression during intergroup encounters. These findings indicate that human modification of food availability can significantly affect movement patterns and intergroup competition in macaques. The observed ranging dynamics related to food provisioning may decrease the efficiency of macaques as seed dispersers and increase predation on their home range, and thus have important consequences for plant regeneration and animal diversity.Abstract in Thai is available with online material.

The effect of anthropogenic resources on the space‐use patterns of golden jackals

et al. 2011

We studied the influence of agricultural villages on space‐use patterns of golden jackals (Canis aureus Linnaeus) in the Mediterranean region of Israel. Villages in our research area attract jackals due to poor sanitation conditions in and around villages. As resources in these villages are abundant and predictable, we expected that space‐use patterns of jackals near those villages, including home‐range characteristics and movement paths, would differ from those of jackals inhabiting more natural areas. Using radio‐locations from 16 individuals (8 near villages and 8 from more natural areas), we found that mean home‐range size of jackals close to villages was 6.6 ± 4.5 km2, smaller than mean home‐range size of jackals in more natural areas (21.2 ± 9.3 km2, P = 0.001). Similarly, core area size of jackals near villages was 1.2 ± 0.92 km2, compared to 3.5 ± 1.6 km2 for individuals inhabiting more natural areas (P = 0.004). The core area/home‐range ratio was greater for jackals near villages than for those occupying more natural areas (0.122 ± 0.045 vs. 0.095 ± 0.037, respectively, P = 0.004). Jackals moved little during the day, with day ranges smaller for jackals near villages than away from them (1.65 ± 0.67 vs. 7.5 ± 5.6 km2, respectively, P = 0.028). However, jackals near villages moved as much at night as did jackals in more natural areas, although movement was in a less directional manner. Changes in distribution and predictability of resources due to anthropogenic activity affect not only the home‐range size of jackals, but also how they utilize and move through space. © 2011 The Wildlife Society.
