Published: Sept. 1, 2021

Abstract The Amur tiger ( Panthera tigris altaica ) is critically endangered and also the subspecies of with most restoration potential in China. It challenging to protect large‐ranging carnivores like tigers under increasing pressure human development. To provide a more technically robust foundation for habitat conservation prioritization, we conducted comprehensively empirical analysis based on broadly collected occurrence dataset their prey. We modeled distribution by running an ensemble model integrating nine different algorithms. found that performed well outperformed any individual regarding discrimination ability. used cumulative resistant kernel identify core habitats as high predicted movement density factorial least‐cost paths corridors among locations. are distributed three mountain areas, namely, eastern Wanda Mountain, southern Zhangguangcailing, Laoyeling‐Dalongling. significant protection gaps existing protected areas only cover less than one‐fourth habitats, but this proportion will rise significantly establishment Northeast China Tiger Leopard National Park. Furthermore, ranked spatial priorities expansion area network, simultaneously considering biological socioeconomic dimensions Zonation framework. Our study presented up‐to‐date detailed maps important China, which can quantitative guidance effort maximize efficiency initiatives at regional scale.

A spatially explicit analytical framework to assess wildfire risks on brown bear habitat and corridors in conservation areas

Fire Ecology, Journal Year: 2022, Volume and Issue: 18(1)

Published: Jan. 24, 2022

Abstract Background Humans have altered fire regimes across ecosystems due to climate change, land use and increasing ignition. Unprecedented shifts in affect animals contribute habitat displacement, reduced movement, increased mortality risk. Mitigating these effects require the identification of habitats that are susceptible wildfires. We designed an analytical framework incorporates risk mapping with species distribution modeling identify key Ursus arctos high probability Iran. applied random forest algorithm for mapping. also modeled brown bear predicted connectivity between them using models analysis, respectively. Finally, map, critical habitats, corridors were overlaid spatially at fire. Results identified 17 5245 km 2 connecting them, 40.06% 11.34% which covered by conservation areas, Our analysis showed 35.65% 23.56% Conclusions Since bears this semi-arid landscape rely on forests higher altitudes, it is likely shifting changing modifications reduce extent future. While not well known how affects bears, identifying its where wildfires occur first step manage potential impacts from species.

Multi-scale habitat modelling of latrine site selection by sympatric carnivores in an Albany Thicket landscape, South Africa

Landscape Ecology, Journal Year: 2024, Volume and Issue: 39(3)

Published: Feb. 17, 2024

Abstract Context Understanding how species select resources often requires assessing the environment at different spatial scales. Although function of latrines in animal communication and social interactions has been studied several carnivores, latrine site selection remains under-researched. Objectives We aimed to describe characteristics determine environmental factors, operating scales, that drive by two sympatric genet ( Genetta genetta G. tigrina ) an Albany Thicket landscape (South Africa). Methods used a multi-scale modelling framework investigate comparing with random points four then adapted match-control design derive probability selection. Results At fine scale, genets selected sites located steeper slopes boasting higher availability favourable micro-structures (e.g., burrows, termite mounds, hollow branches). were positively associated riverine forest corridors where they occurred clusters. Genets avoided open areas high terrain ruggedness place their latrines. The best scale-independent model revealed importance edge habitats like and, lesser extent, dirt roads. Conclusions This study outlines including scale variables studies, as may reveal features are crucial for marking behaviour. Overall, our findings highlight scales which various factors influence most. Based on results, we suggest management practices maintain preserving across landscapes.

Energy‐based corridor identification for mammals between protected areas in Iran

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(6)

Published: June 1, 2024

Body mass plays a crucial role in determining the mass-specific energy expenditure during terrestrial locomotion across diverse animal taxa, affecting patterns. The landscape concept offers framework to explore relationship between characteristics and expenditure, enhancing our understanding of movement. Although approach solely considers topographic obstacles faced by animals, its suitability compared previous methods for constructing resistance maps delineating corridors has not been comprehensively examined. In this study, we utilized enerscape R package generate kilocalories (kcal) incorporating digital elevation models (DEMs) body size data (kg). We assigned sizes ranging from 0.5 100 kg encompass wide range small large mammals Iran, adjusting maximum dispersal distances accordingly 50 200 km. By analyzing these scenarios, produced four each size. Next, identified potential protected areas Iran using Linkage Mapper toolkit examined barriers pinch-points along paths. Our study revealed significant findings regarding shared Iran's landscape. Despite their differing requirements, many were found be both mammal species. For example, 206 weighing 500 g, which also recognized as least-cost paths mammals. Thus, embracing comprehensive method map creation, one that incorporates species-specific traits human infrastructure becomes imperative accurately identifying consequently pinpointing pinch points barriers.
