Asian elephants are a principal cause of human-wildlife conflict. This results in the death/injury and humans large-scale crop property damage. Most current human-elephant conflict (HEC) mitigation tools lack flexibility to accommodate ecological needs ineffective at reducing HEC long-term. Here we review common used Asia potential Aversive Geofencing Devices (AGDs) manage problem elephants. AGDs can be configured monitor animal movements real-time deliver auditory warnings followed by electric stimuli whenever animals attempt move across user-specified virtual boundaries. Thus, expected condition avoid receiving shocks keep them away from virtually fenced areas, while providing alternative routes that modified if required. Studies conducted using with other species provide an overview their conditioning wild animals. We recommend efficacy welfare impact evaluated captive along public perception on as means addressing inherent deficiencies tools. If could successfully conditioned fences, then resolve many incidents throughout Asia.

Abstract Balancing development and conservation is one of the major challenges for modern societies. Negative human–wildlife interactions, especially crop raiding by wildlife, greatly undermine this objective. Jilin Province in Northeast China encompasses ecosystems high biodiversity value but endures serious losses yields due to wild boars ( Sus scrofa ). Mitigation measures have been hindered knowledge gaps boar damage patterns. Our objective was investigate how responded human‐dominated landscapes, evaluating landscape patterns at multiple ecological scales, thus providing a provincial map risk assist with mitigation. We used 1,144 coordinates from 2009 2013 train multi‐scale models maximum entropy algorithm. Damage highest on gentle slopes heterogenous landscapes composed fragmented plantations cropland, edge density among small discontinuous patches, dense settlements countryside areas sporadic road networks. Scale had substantial effect relationships between landscapes. recommend mitigating conflict improving compensation system reducing frequency through repelling, electric fencing, dissuasive feeding.

Maintenance of sufficient habitat for large terrestrial mammals in increasingly human-dominated landscapes is challenging. Wild Asian elephants China were historically widespread, but now comprise 293 individuals confined to three prefectures southwestern Yunnan Province. Effective legal protection has permitted population growth Chinese elephants, it not known why are the portion Yunnan, nor there been a comprehensive assessment extent, quality and carrying capacity within their potential range. We used multiscale multivariable species-distribution modelling evaluate effects topography, land use, transport infrastructure settlements on suitability throughout during 2012 – 2021, using data from literature records, field surveys camera traps. Elephant distribution was strongly influenced by presence forest measured at coarse (32-km) scales, with fragmentation percentage cover together accounting 64% total variability, whereas had relatively minor effect (1.7%).

The Arabian leopard (Panthera pardus nimr) has experienced dramatic range and population contractions over the last century. Conservation efforts for this felid focused on captive breeding identification of suitable conditions reintroductions. With study, we unravelled historical collaring direct observations data to understand spatial use leopards recorded in region Israel West Bank (IWB). Through datasets occurrence, characterised habitats, assessed niche overlap with leopard's main prey, Nubian ibex (Capra nubiana), evaluated their distributions respect currently protected habitats. We estimated home-ranges employing area-corrected density kernel methods investigated through multiple scales habitat modelling. Average home ranges were 73.24 ± 47.91 km2 77.46 54.94 km2, depending time lag adopted. Ecological response predictors highlighted reliance by both predator prey same characteristics, suggesting they occupied essentially identical niches. These characteristics intermediately rugged topographic high indices vegetation scarcely populated desert environments, mostly encompassed within areas. distribution overlapped substantially according several metrics. Notably, more than half potential species is areas military zones. Given coincidence ecological requirements, highly congruent distributions, an important step towards future reintroduction will include gaining a better understanding populations, alongside attention practicality enforcing protection.

Abstract Many Asian elephant populations inhabit fragmented human‐dominated landscapes. Human–elephant conflict (HEC) has intensified in such regions, resulting the deaths of hundreds people and elephants each year. Controversy between stakeholders then arises as debate merits HEC mitigation approaches, stifling progress. We conducted a survey to evaluate opinions experts, farmers others who have not experienced ( n = 611), on causes HEC, importance of, conservation co‐existence with elephants, acceptability effectiveness potential methods.

The next-generation sequencing rbcL gene from non-invasively collected fecal samples conducted addition transect surveys camera-trapping along known trails. With survey, we identified 31 plant species foraged by elephants. analysis total 90 dung samples. Only nine were detected at rates greater than 1% all Poaceae (47.69%), Moraceae (21.25%), Musaceae (11.24%) have highest family level. We examined whether differences existed between sexes, age groups, individuals; however, significant found individuals. useful foraging elephants, which could help further understanding interactions habitat reserve inform future management decisions related areas. core with relatively high abundance provide guidance for restoration cultivation food bases. local plantations where prefer feed be moved farther away, making them inaccessible
