Animal-derived products have an important role in treating many health conditions and have widely been used across cultures. In South Asia, ethnozoological research has been conducted only by a small number of researchers. Therefore, this area of research needs further exploration in order to preserve the eroding ethnozoological knowledge of medicinal animals severely affected by ongoing social change. This study was conducted in the region of Jammu and Kashmir from February 2019 to August 2021. The study was carried out among eight different ethnic groups living in the region. A total of 374 informants were selected and data were collected through semi-structured interviews and verified through group discussions. Data was analyzed using different statistical tools, including R 4.0.0. The cross-cultural data were compared through Bioinformatics and Evolutionary Genomics software and later subjected to further analysis, applying Pearson correlation and ordination techniques (Principal Component Analysis). We recorded a total of 79 animal species being used by the eight studied ethnic groups in the region. Wild animal species were mainly used for therapeutic purposes. Chest infections, sexual problems, and paralysis were frequently treated diseases. Flesh was the most commonly part used. The cross-cultural comparison showed a remarkable heterogeneity in the use of the animals among the different groups, which could be an effect to the historical sociocultural stratifications, as well as different religious affiliation of certain groups preventing them to forage or hunt certain animals. Some groups however showed prominent overlap of uses of some recorded species. For instance, Lerwalerwa and Bubalus bubalis were commonly used by both Gujjar and Pahari, which could be referred to the fact that they have gone through significant socio-cultural contact, and they are exogamous to each other. The Pearson correlation coefficient supported the strength and direction of an association between ethnic groups and regions. The study makes an important contribution to the field of ethnozoology in the Himalayas by providing insights to understand the historical human and nature relationships and supplying a baseline for developing future conservation efforts in the region to protect the wild fauna

People have traditionally relied on fish to supply their major food and healthcare needs all across the world. However, there has been little focus on the traditional dietary, cultural identity, and integrity of traditional food systems in many rural Himalayan populations. The current study looks into the use of fish in traditional food and foraging practices, as well as its role in local traditional medicine and cultural practices. Semi-structured interviews and group discussions were used to collect data in the years 2020–2021. The data were analyzed using various statistical indices such as the fidelity level (FL), rank order priority (ROP), and relative popularity level (RPL). The data were then classified through a heat map, and ordination techniques were used to refine them even further. The current study identified 20 fish species of five families, with Cyprinidae (70%) as the dominant family. Three unique traditional fish preservation techniques were documented, namely: (1) smoking, (2) sun drying, and (3) pickling. The smoked fish are locally called fari, sun-dried fish are known as hugaad, and pickled fish are gaad anchaar. As a result of rapid modernization, fish has become a symbol of social class in the valley. In total, 17 diseases were identified, with joint pain being treated by the greatest number of species (N = 10). Flesh (43%) was the most commonly used part to treat various diseases. The mode of application of various fishbody parts for treating a variety of diseases was most commonly peroral (65%), followed by topical (35%). Schizopyge niger demonstrated the highest level of fidelity (82%) for joint pain. Schizopygeniger, Schizothorax curvifrons, Catla catla, Schizothorax esocinus, Schizothorax labiatus, and Schizothorax plagiostomus were the most popular (relative popularity level = 1.0). The rank order priority of six species was above 55 (Schizothorax plagiostomus (59.18), Labeo dyocheilus (61.99) Schizothorax labiatus (64.28), Schizothorax esocinus (68.36), Schizothorax curvifrons (73.19), and Schizopyge niger (82)). Two principal groups of six ethno-zoological categories (medicine, food, black magic, poultry, agricultural, and recreational) were identified using cluster analysis. Fish are also important as a source of livelihood and are closely associated with a local ethnic group known as Hanji/Haanz, who have extensive knowledge of ecology of the local fish species. Our research will contribute to filling a knowledge gap in the Kashmir Himalayan region, with policy implications for the protection and preservation of high-quality traditional knowledge for future generations. The findings of this documentation study can be used as an ethnopharmacological foundation for selecting fish in future pharmaceutical research.

The distribution of large ungulates is more often negatively impacted by the changing climate, especially global warming and species with limited distributional zones. While developing conservation action plans for the threatened species such as the Himalayan goral (Naemorhedus goral Hardwicke 1825; a mountain goat that mostly inhabits rocky cliffs), it is imperative to comprehend how future distributions might vary based on predicted climate change. In this work, MaxEnt modeling was employed to assess the habitat suitability of the target species under varying climate scenarios. Such studies have provided highly useful information but to date no such research work has been conducted that considers this endemic animal species of the Himalayas. A total of 81 species presence points, 19 bioclimatic and 3 topographic variables were employed in the species distribution modeling (SDM), and MaxEnt calibration and optimization were performed to select the best candidate model. For predicted climate scenarios, the future data is drawn from SSPs 245 and SSPs 585 of the 2050s and 2070s. Out of total 20 variables, annual precipitation, elevation, precipitation of driest month, slope aspect, minimum temperature of coldest month, slope, precipitation of warmest quarter, and temperature annual range (in order) were detected as the most influential drivers. A high accuracy value (AUC-ROC > 0.9) was observed for all the predicted scenarios. The habitat suitability of the targeted species might expand (about 3.7 to 13%) under all the future climate change scenarios. The same is evident according to local residents as species which are locally considered extinct in most of the area, might be shifting northwards along the elevation gradient away from human settlements. This study recommends additional research is conducted to prevent potential population collapses, and to identify other possible causes of local extinction events. Our findings will aid in formulating conservation plans for the Himalayan goral in a changing climate and serve as a basis for future monitoring of the species.

Sexual segregation, the tendency to seasonally live in groups comprised of separate sexes, is widespread in sexually dimorphic polygynous ungulates. The causes for such segregation are still being studied and debated to arrive at a universal explanation. We assessed sexual segregation in the markhor, Capra falconeri—a dimorphic mountain ungulate inhabiting a seasonal temperate environment. We observed markhor herd composition, gender-specific diet, and habitat use over 3 years and multiple seasons. We tested the predictions of the Reproductive Strategy-Predation Risk Hypothesis (RSH) that focuses on offspring security, and the Forage Selection-Sexual Dimorphism Hypothesis (FSH) based on different foraging needs between the sexes due to size dimorphism. Generalized linear models were used to identify the important variables that best explained segregation in markhor. Male and female markhor showed a tendency to segregate throughout the year outside the mating season. Female markhor were confined to cliffs with relatively less forage cover, whereas males used areas with relatively better forage away from the security of cliffs. Females also occurred at lower elevations compared to males. Social segregation prevailed during pre-parturition and continued until autumn when the offspring were older, indicating a role of other factors besides predation risk. Sexual segregation in markhor was influenced by multiple mechanisms.

The impact of a changing climate, particularly global warming, often harms the distribution of pheasants, particularly those with limited endemic ranges. To effectively create plans of action aimed at conserving species facing threats such as the Western Tragopan, (Tragopan melanocephalus; Gray, 1829; Galliformes, found in the western Himalayas), it is crucial to understand how future distributions may be affected by anticipated climate change. This study utilized MaxEnt modeling to assess how suitable the habitat of the targeted species is likely to be under different climate scenarios. While similar studies have been conducted regionally, there has been no research on this particular endemic animal species found in the western Himalayas throughout the entire distribution range. The study utilized a total of 200 occurrence points; 19 bioclimatic, four anthropogenic, three topographic, and a vegetation variable were also used. To determine the most fitting model, species distribution modeling (SDM) was employed, and the MaxEnt calibration and optimization techniques were utilized. Data for projected climate scenarios of the 2050s and 2070s were obtained from SSPs 245 and SSPs 585. Among all the variables analyzed; aspect, precipitation of coldest quarter, mean diurnal range, enhanced vegetation index, precipitation of driest month, temperature seasonality, annual precipitation, human footprint, precipitation of driest quarter, and temperature annual range were recognized as the most influential drivers, in that order. The predicted scenarios had high accuracy values (AUC-ROC > 0.9). Based on the feedback provided by the inhabitants, it was observed that the livability of the selected species could potentially rise (between 3.7 to 13%) in all projected scenarios of climate change, because this species is relocating towards the northern regions of the elevation gradient, which is farther from the residential areas, and their habitats are shrinking. The suitable habitats of the Tragopan melanocephalus in the Himalayan region will move significantly by 725 m upwards, because of predicted climate change. However, the fact that the species is considered extinct in most areas and only found in small patches suggests that further research is required to avert a further population decline and delineate the reasons leading to the regional extinction of the species. The results of this study can serve as a foundation for devising conservation strategies for Tragopan melanocephalus under the changing climate and provide a framework for subsequent surveillance efforts aimed at protecting the species.
