Abstract Human presence exerts complex effects on the ecology of species, which has implications for biodiversity persistence in protected areas experiencing increasing human recreation levels. However, difficulty separating effect species from other environmental or disturbance gradients remains a challenge. The cessation activity that occurred with COVID-19 restrictions provides ‘natural experiment’ to better understand influence wildlife. Here, we use closure within heavily visited and highly national park (Glacier National Park, MT, USA) examine how ‘low-impact’ recreational hiking affects spatiotemporal diverse mammal community. Based data collected camera traps when was closed then subsequently open recreation, found consistent negative responses across most our assemblage 24 fewer detections, reduced site use, decreased daytime activity. Our results suggest dual mandates parks conserve promote have potential be conflict, even presumably innocuous activities.

Humans greatly influence the ecosystems they live in and lives of a wide range taxa share space with. Specifically, human hunting harvesting has resulted many species acclimating via diverse behavioral responses, often quite rapidly. This review provides insights into how can elicit changes. These responses emerge from species’ previous evolving ability to assess risk imposed by hunters respond accordingly; predator–prey game thus ensues, where both players may change tactics over time.

Human activities impact ecosystems globally, and understanding human–wildlife coexistence is crucial for species conservation. This study analyzed trends in local wildlife populations before during the COVID-19 pandemic to assess their response human disturbance. From 2017 2022, 60 camera sites were monitored, seven with largest population size—excluding rodents—were selected analysis. The results revealed that presence of humans (p = 0.025) domesticated animals (cats dogs, p 0.002) significantly decreased pandemic. Conversely, five (except Tibetan macaque mainland serow) showed habitat expansion growth < 0.05), which may be related avoidance or artificial structures such as roads tourism facilities. In addition, analysis most species, except wild boar, adjusted activity patterns, showing increased diurnal when disturbances reduced (RR > 0). These findings suggest adapt behaviors avoid presence. highlights negative impacts on emphasizes need stronger conservation management efforts mitigate scenic areas.

Madagascar is considered one of the top global biodiversity hotspots while at same time among world's least developed countries. Pressing socioeconomic needs such as food provision often lead to unsustainable land uses and widespread loss, fragmentation degradation natural habitats. Thus, ascertaining effects small conserved sites urgent in order show their benefits identify costs attain sustainable rural development on island. Here, we used structured questionnaires two surveys key local stakeholders, including 1) managers three smaller than 100 ha, 2) communities living around (cases) similar neighbouring unaffected by those (controls), following a Before-After-Control-Impact design. Median income did not differ between case control communities, although reported better self-perception economic situation wider availability basic services. Substantial revenues from tourism accrued only community conveniently located, community-managed site: Anja Community Reserve. No differences establishment were found sex, age or education levels members. Exploitation resources was either prohibited (two sites) severely restricted (one site). As result, tended collect fewer nearby areas communities. Contrary expectations, less impact during COVID-19 pandemic even though visitors reduced zero, which likely indicates greater resilience due previous investments ecosystem Successful, bottom-up replicable approaches locally manage sustainably are urgently needed country with rich vanishing biodiversity, weak institutions, high poverty rates strong dependence for subsistence.

To better inform human‐tiger conflict (HTC) management in Aceh, Sumatra, we analysed 96 cases of HTC reported to, and verified by, local government authorities between 2017 2021. Livestock depredation (49%) people reporting fear or anxiety upon tiger sightings (39%) comprised most incidents. We found significant differences the frequency among land cover types Aceh ( x 2 = 160.4, df 4, p < 0.001). During our study period, oil palm plantations covered 9.5% Aceh's surface but represented dominant habitat type 46.9% province's cases.

Abstract The long‐term conservation of species at risk relies on numerous, and often concurrent, management actions to support their recovery. Generally, these are habitat‐based while others focused a species' position within its ecological community. Less studied the impacts from human presence, despite evidence that activity may reduce area functionally available for occupancy or resource acquisition. In winter 2020/2021, COVID‐19‐related travel restrictions led reduction in helicopter‐assisted back‐country skiing (heli‐skiing). We examined how reductions heli‐skiing (termed anthropause) affected movement ecology selection southern mountain caribou ( Rangifer tarandus ) as compared two prior years (2018/2019 2019/2020) following year when resumed (2021/2022). found home‐range size was average 80–120% larger during anthropause than normal heli‐ski operations. Movement rates also varied among periods, with (11.9 km 2 /day) being higher 2019/2020 (7.8 2021/2022 (8.7 /day), though similar 2018/2019 (12.2 /day). Resource periods did not differ, consistently selecting old forests, high elevations gentle terrain. These results suggest recreation, specifically heli‐skiing, be limiting access resources caribou. This limitation arises through reduced suitable late‐winter habitat, relative is occurring – consistent Encounter Theory. While demographic effects were here, likely compounds other stressors known affect population viability this study demonstrate impact recreation can have wildlife highlight need consider forms developing recovery plans.
