“…Similar patterns have been observed recently in a similar study in Vía Maxus, where the red brocket deer increases the proportion of hours of nighttime activity (Salvador 2015) in sites that are close to human settlements (i. e., higher accessibility and hunting). The shift in the activity pattern toward nighttime in the presence of hunting has been observed previously in the red brocket deer, specifically in Argentina (Di Bitetti et al 2008), as well as in other ungulate species, e. g., the Mediterranean mouflon Ovis gmelini musimon (Marchand et al 2014), and the sika Cervus nippon (van Doormaal et al 2015). These observations support that both the collared peccary and the red brocket deer display plasticity to adapt their activity pattern in response to human intervention, which partially explains their permanence in sites like Vía Maxus in Yasuní, where hunting is intense, although other factors such as source-sink dynamics may be more important (Espinosa et al 2014).…”

Ungulates are one of the most important groups in terrestrial ecosystems across the tropics. Also, ungulates are an important source of protein for people who inhabit tropical forests, and numerous studies have been conducted to evaluate the impact of hunting on the size of ungulate populations. However, little is known about other potential effects of hunting on these species. This study aims to analyze the effect of landscape accessibility to hunters on the daily activities of ungulates in Yasuní Biosphere Reserve, a protected area located in the Amazon region of Ecuador. We compared activity patterns (i. e., distribution of hours of activity along the day) and activity levels (i. e., proportion of hours of the day that an animal is active) for five ungulate species (white-lipped peccary Tayassu pecari, collared peccary Pecari tajacu, red brocket deer Mazama americana, brown brocket deer M. nemorivaga, and tapir Tapirus terrestris) in four sites differing in the degree of access to hunters. To this end, in each of the four study areas, a grid of camera traps was placed within a polygon of approximately 100 km 2 ; traps operated continuously for three to four consecutive months. We recorded the date and time of detection for each species. Daily activity patterns and activity levels were estimated with kernel density analysis for circular data. Our work included a total of 9,506 effective trapping days for the four study sites, resulting in 1,063 separate records of the five ungulate species. In the four study areas, the brown brocket deer and the two species of peccaries concentrated their activity in daytime hours. The red brocket deer was most active in twilight hours, and the tapir was primarily nocturnal. At sites most accessible to hunters, the activity patterns of the collared peccary included a higher proportion of nighttime hours. The red brocket deer also seemed to increase the proportion of nighttime hours of its daily activity. The overall daily activity level was higher in the site with higher accessibility, but was statistically significant only for the collared peccary and the red brocket deer. Our findings include moderate statistically significant evidence suggesting that the access of hunters to the landscape influences the daily activity of ungulates in Yasuní. One species that is clearly affected by the access of hunters is the collared peccary, which becomes more nocturnal and increases its nighttime hours of activity when accessibility to hunters is higher. When our results are compared with other studies, it is evident that the species may display different behavioral responses to hunting, and that these responses may vary with the scale of analysis. This study was limited by sample sizes, which did not allow performing comprehensive analyses for all five species. To further understand the effects of hunting and other human activities on animal behavior, additional studies specifically designed for this purpose should be conducted.Los ungulados constituyen uno de los grupos de mayor import...

“…Hunting was forbidden in a 1658 ha central wildlife reserve, in which 16% of GPS-collared animals locations were recorded during the hunting period. As behavioural responses of mouflon to hunting disturbance also occurred in this protected area (Benoist et al, 2013;Marchand et al, 2014), these data were not distinguished in our analyses.…”

“…It has also involved behavioural and life history consequences for mouflon (Benoist, Garel, Cugnasse, & Blanchard, 2013;Garel et al, 2007;Marchand et al, 2014). During the study period (2003e2010), hunting occurred from 1 September to the end of February.…”

“…During the study period (2003e2010), hunting occurred from 1 September to the end of February. On average 378 (SD ¼ 109) animals were harvested per year (out of probably more than 2500 individuals; Marchand et al, 2014), evenly distributed between both sexes. Driven hunts with hounds were carried out on Wednesdays, Saturdays, Sundays and public holidays, target species being wild boar, Sus scrofa scrofa, female mouflon (68% of harvested females) and occasionally roe deer, Capreolus capreolus.…”

“…The presence of tourists has been reported to affect the activities of wildlife [Marchand et al, 2014] and this may apply in Komodo National Park, notably in Loh Buaya valley, Rinca Island. Crab-eating macaques that have adapted to humans, including tourists [Eudey, 2008], may be especially available as prey for the dragons.…”

We investigated the proportion of crab-eating macaques in the diet of Komodo dragons and quantified the spatial habitat use between the species as a proxy for predation threat and in relation to prey availability due to ecotourism. In 2013, in Loh Buaya valley of Rinca Island, Komodo National Park, we conducted macroscopic identification of hairs, claws, dentition and osteological remains of consumed prey. For habitat use, we quantified the use of vertical strata by macaques through focal animal sampling. For Komodo dragons in the valley, macaques were a significant component of their diet (20.7%), ranking second after rusa deer (58.6%); the proportion of macaques we observed in the diet is much higher than in previous studies. An increased use of the forest floor by macaques at this site may increase their vulnerability as a prey species, especially in the daytime when tourist presence impacts the availability of other favoured prey species.
