“…In Kazakhstan, the saiga antelope is suspected of spreading the abomasal nematode Marshallagia marshalli between sheep populations hundreds of kilometres apart during its northern migration [ 48 ]. In data-limited situations, the use of social and ecological information has proven useful in indicating the transmission of disease between the saiga antelope and livestock [ 49 ], and equivalent information could also prove valuable when understanding helminth transmission. For example, if deer hunters provide samples for nematode analysis, follow-up surveys could ask them where the deer graze and if they are in close proximity to livestock pasture.…”

Wild ruminants are susceptible to infection from generalist helminth species, which can also infect domestic ruminants. A better understanding is required of the conditions under which wild ruminants can act as a source of helminths (including anthelmintic-resistant genotypes) for domestic ruminants, and vice versa, with the added possibility that wildlife could act as refugia for drug-susceptible genotypes and hence buffer the spread and development of resistance. Helminth infections cause significant productivity losses in domestic ruminants and a growing resistance to all classes of anthelmintic drug escalates concerns around helminth infection in the livestock industry. Previous research demonstrates that drug-resistant strains of the pathogenic nematode Haemonchus contortus can be transmitted between wild and domestic ruminants, and that gastro-intestinal nematode infections are more intense in wild ruminants within areas of high livestock density. In this article, the factors likely to influence the role of wild ruminants in helminth infections and anthelmintic resistance in livestock are considered, including host population movement across heterogeneous landscapes, and the effects of climate and environment on parasite dynamics. Methods of predicting and validating suspected drivers of helminth transmission in this context are considered based on advances in predictive modelling and molecular tools.

“…Proper monitoring of tiger and prey populations (through active patrolling) and community-driven plans are required to assess the density of livestock/feral cattle within tiger habitats so necessary management interventions can be prepared. Once implemented, they can reduce tiger-human conflict and probability of disease transmission from domestic ungulates to wildlife (Martin et al 2011; Khanyari et al 2021). Finally, detailed investigation of any tiger death across India (both natural and retaliatory killings) needs to be conducted and records need to be examined thoroughly (as they had shown to reduce up to 50% decrease in population size in Russian far east, Miquelle et al 2006), to ascertain causal reasons for appropriate management implications.…”

Large carnivores strongly shape ecological interactions within their respective ecosystems, but experience significant conflicts with human across their range due to their specific ecological resource requirements. The tiger (Panthera tigris) typifies the challenges faced by the large carnivore communities globally. India retains majority of the global tiger population with significant numbers outside protected areas (PAs) that are involved in conflicts from livestock predation and human/tiger death. To understand the prey selection patterns and spatio-temporal patterns of livestock predation-related conflict issues we investigated tiger food habits across the Indian part of the Terai-Arc Landscape (TAL), a globally-important tiger conservation landscape in India. We used 510 genetically-confirmed tiger faeces collected across the landscape and ascertained 10 wild and livestock as major prey species. Large-bodied species (sambar, swamp deer, nilgai, chital, wild pig and livestock) comprised ~94% of tiger diet, with sambar, chital and livestock were the major prey species. Habitat-specific (Shivalik-Bhabar and Terai) analyses show significantly different pattern of prey selections determined by abundance and prey body weight. Results also suggest that PA and non-PAs of Terai habitat are more prone to livestock depredation-related conflicts, and careful management interventions and community involvements are required to reduce such threats. We suggest long-term plans including population estimation of tigers and prey outside PAs, reducing grazing pressures and cattle enumeration, detailed investigation of tiger deaths etc. to ensure future tiger sustainability across this habitat.

“…There is even a perception that in Ural, exploitative resource competition between saigas and livestock might be occurring (Satke, 2020). Given this background and that livestock densities are currently low in the other populations (Dara et al, 2020;Khanyari, Robinson, Morgan, Brown, et al, 2021), saigas are more likely to come in contact with livestock in this population than the others, making it a relevant case study site. Historically, Kazakh pastoralists followed long-distance seasonal migratory routes.…”

“…Saigas are most likely to share pasture with outlying livestock(Khanyari, Robinson, Morgan, Brown, et al, 2021) which have significantly lower worm burdens than village-based livestock, and comparable burdens to saigas. However, this situation may worsen with further increase in livestock numbers and increased resource competition.…”
