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.

- The study explores how social connections among female Central Himalayan Langurs (CHL) relate to their survival and reproductive success, focusing on factors like dominance rank, age, genetic relatedness, and the presence of females with infants.
- Researchers analyzed grooming networks to illustrate different strategies: high-ranking females build numerous relationships, while those with dependent infants maintain strong bonds, and subadult females serve as vital links within the social structure.
- The findings highlight how various behavioral strategies not only affect individual fitness but also play a crucial role in the overall social dynamics and survival of the group.
Autism spectrum disorder (ASD) is a heterogenous neurodevelopmental disorder marked by functional abnormalities in brain that causes social and linguistic difficulties. The incidence of ASD is more prevalent in males compared to females, but the underlying mechanism, as well as molecular indications for identifying sex-specific differences in ASD symptoms remain unknown. Thus, impacting the development of personalized strategy towards pharmacotherapy of ASD.

- The study focuses on how Central Himalayan Langurs (CHL) respond to predation by dogs, revealing insights into predator-prey relationships within primatology.
- Over two years, researchers observed 312 interactions, noting serious attacks that resulted in fatalities among langurs, particularly affecting vulnerable group members.
- Male langurs exhibited varying anti-predator behaviors based on their social ties and investment in the group, with long-term males engaging in costly protective actions, while short-term males tended to adopt less risky, self-preserving tactics.
Polycystic ovarian syndrome (PCOS) is a complex endocrine disorder affecting females in their reproductive age. The early diagnosis of PCOS is complicated and complex due to overlapping symptoms of this disease. The most accepted diagnostic approach today is the Rotterdam Consensus (2003), which supports the positive diagnosis of PCOS when patients present two out of the following three symptoms: biochemical and clinical signs of hyperandrogenism, oligo, and anovulation, also polycystic ovarian morphology on sonography.

(Nematoda: Oxyuridae) is described from the Central Himalayan langur, Semnopithecus schistaceus, in Mandal Valley, Chamoli District, Uttarakhand, India, based on mature and immature adults and fourth-stage larvae.
View Article and Find Full Text PDFWater is one of the most important components of an animal's diet, as it is essential for life. Primates, as do most animals, procure water directly from standing or free-flowing sources such as pools, ponds and rivers, or indirectly by the ingestion of certain plant parts. The latter is frequently described as the main source of water for predominantly arboreal species.
