“…For example, dogs have been hunting and eating white-tailed small-eared Galagos Otolemur garnettii lasiotis in Kenya's fragmented landscapes [19]. Similarly, in Madagascar, dogs have also been observed preying on endangered wild ring-tailed lemurs Lemur catta [20], and similar incidents involving langurs and macaques have been reported from comparable landscapes in Asia [21][22][23][24]. The presence of predators, including dogs, profoundly influences primate behavior and activity patterns.…”

Globally, habitat fragmentation has increased the proximity between wildlife, humans, and emerging predators such as free-ranging dogs. In these fragmented landscapes, encounters between primates and dogs are escalating, with primates often falling victim to dog attacks while navigating patchy landscapes and fragmented forests. We aim to investigate how these primates deal with the simultaneous threats posed by humans and predators, specifically focusing on the adaptive strategies of Central Himalayan langur (CHL) in the landscape of fear. To address this, we conducted a behavioral study on the CHL in an agro-forest landscape, studying them for a total of 3912 h over two consecutive years. Our results indicate that, compared to their most common resting behavior, CHLs allocate more time to feeding and locomotion, and less time to socializing in the presence of humans and predatory dogs. Additionally, they exhibit increased feeding and locomotion and reduced social behavior in agro-forest or open habitats. These behavioral patterns reflect adaptive responses to the landscape of fear, where the presence of predators significantly influences their behavior and resource utilization. This study suggests measures to promote coexistence between humans and wildlife through the integration of effective management strategies that incorporate both ecological and social dimensions of human–wildlife interactions.

“…P. femoralis is physically slim and slender, covered in black fur at dorsal area and white patches at ventral area down to thigh with no white patches found at the tail area (Groves, 2001). Although normally found covered in black fur, recent discovery reported two brown morph individuals of P. femoralis found in Kota Tinggi (Najmuddin et al, 2020a). Generally, P. femoralis are herbivores but also consume fruits and seeds as well (Caton, 1990;Nijboer, 2006;Kirkpatrick, 2017).…”

Banded langur (Presbytis femoralis) is an endangered leaf-eating colobine, found in Johor and Pahang in Malaysia. However, with less than 500 individuals reported to be surviving in Johor, their behaviour and ecology remain unknown among primatologists. This study provides the first systematic data on the daily activity budget of the species in Malaysia. Scan sampling technique was used to observe and record P. femoralis behaviour with 10 min interval starting from February 2018 to November 2018. The results are based on 186 h and 20 min of direct observation in the wild. The animals spent most of the time for resting (43 ± 13%) followed by moving (26 ± 9%), feeding (26 ± 7%), social activities (4 ± 3%), and others (1 ± 0%). Seasonality significantly influences the activity budget of the animals resulting in increased resting and moving in the non-fruiting season. Feeding activities decreased in the non-fruiting season compared with the fruiting season, whereas social activities remained the same. We concluded that the daily activity budget of P. femoralis in this study portrays comparable behavior to other langurs in Malaysia that would help in conservation and management of the species in terms of understanding temporal and spatial requirements of P. femoralis in a highly fragmented habitat.
