Abstract Protected areas are essential tools for reducing loss of global biodiversity. To fulfill their ecological functions, protected must be connected to surroundings, a requirement that is difficult meet in landscapes intensively disturbed by anthropogenic activities. Therefore, protecting movement corridors at the edges crucial, especially species with broad habitat needs, such as American marten ( Martes americana ). However, selection and space use patterns dynamic processes, so we could expect functional connectivity would vary temporally response changing environmental conditions levels human In this study, aimed predicting location Forillon National Park its periphery during two contrasted periods (snow‐free: May–November; snow‐covered: December–April). We used “seasonal” resource functions identify core (interpreted circuit “nodes”) CircuitScape delineate between them based on electrical theory. Habitat differed periods, martens avoiding open areas, high elevations road proximity snow‐free period, while closer secondary roads but selecting primary housing structures snow‐covered period. Consequently, partially periods. Functional was favored presence forest patches both being constrained environments, Our study highlights importance modeling fine temporal scales order provide requirements each period annual cycle.

Regional ecological security is a pressing issue in the context of escalating human-environment conflicts. Ecological networks(ENs), fundamental tool for characterizing ecosystems, have enabled further quantitative analysis at micro level by integrating with complex networks recent years. However, most studies neglect unreliability unweighted and dynamic characteristics ENs. This paper takes Sichuan Basin as research area adopts following methods. Firstly, it integrates landscape ecology ecosystem services to construct ENs using Linkage Mapper.

ABSTRACT Anthropogenic interference causes ecological fragmentation and vulnerability, weakening urban ecosystems' adaptive capacity. The network is based on the principles of landscape ecology, connecting resource patches through linear corridors to protect biodiversity integrity, enhance environmental carrying capacity, improve ecosystem resilience. However, current research resilience often relies single methods scales, overlooking potential discrepancies between different approaches scales. This study uses Zhejiang construct networks with structural, functional, integrated at provincial, agglomeration, city levels. performance these in protecting structure, maintaining function, ensuring overall was compared, yielding following results: First, spatial output consistency source areas across scales for three ranged from 50.48% 97.81%. Second, approach not optimal all goals. structure‐oriented method demonstrated cross‐scale applicability structural goal, while function‐oriented strategy performed well functional Third, scale analysis showed results provincial agglomeration levels when meeting same objectives, but level. By expanding methodologies perspectives field resilience, this assesses It found that do always effectively coordinate multiple protection objectives; thus, large‐scale strategies cannot be directly applied smaller practical applications. proposes validates a multi‐scale, multi‐method framework assessing networks. reveals differences methods, providing valuable theoretical insights guidance future particularly regarding

Climate change has severely impacted many species, causing rapid declines or extinctions within their essential ecological niches. This deterioration is expected to worsen, particularly in remote high-altitude regions like the Himalayas, which are home diverse flora and fauna, including mountainous ungulates. Unfortunately, of these species lack adaptive strategies cope with novel climatic conditions. The Red Goral (Naemorhedus baileyi) a cliff-dwelling classified as “Vulnerable” by IUCN due its small population restricted range extent. most all goral residing temperate mountains northeastern India, northern Myanmar, China. Given population, this highly threatened climate habitat disruptions, making mapping modeling crucial for effective conservation. study employs an ensemble approach (BRT, GLM, MARS, MaxEnt) distribution assess distribution, suitability, connectivity addressing critical gaps understanding. findings reveal deeply concerning trends, model identified only 21,363 km2 (13.01%) total extent suitable under current limited alarming, it leaves very little refuge thrive. Furthermore, situation compounded fact that around 22.29% falls protected areas (PAs), further constraining species’ ability survive landscape. future projections paint even degraded scenarios, predicted decline over 34% excessive fragmentation In addition, present identifies precipitation seasonality elevation primary contributing predictors species. nine designated transboundary PAs among them highlight role supporting survival time.

Maintaining and restoring ecological connectivity will be key in helping to prevent reverse the loss of biodiversity. Fortunately, a growing body research conducted over last few decades has advanced our understanding science, which help inform evidence-based conservation actions. Increases data availability computing capacity have helped dramatically increase ability model functional using more sophisticated models. Keeping track these advances can difficult, even for scientists practitioners. In this article, we highlight some from past decade outline many remaining challenges. We describe efforts biological realism models by, example, isolating movement behaviors, population parameters, directional movements, effects climate change. also discuss considerations when focal or multiple species. Finally, reflect on how account uncertainty transparency reproducibility situations where decisions may require forgoing sophistication simple approaches.

Abstract Context Maintaining connectivity is crucial for wildlife conservation in human-occupied landscapes. Structural modeling (SCM) attempts to quantify the degree which physical features facilitate or impede movement of individuals and has been widely used identify corridors, but its accuracy rarely validated against empirical data. Objectives We evaluated SCM’s ability suitable habitat corridors onagers ( Equus hemionus onager ) through a comparison with functional (i.e., actual individuals) using satellite tracking Methods MaxEnt predict three SCM approaches: circuit theory, factorial least cost path, landscape approaches corridors. The performance was independently collected GPS telemetry Results Onagers selected water sources dense vegetation while avoiding areas grazed intensely by livestock. SCMs identified similar were interrupted roads, affecting major high-flow overlapped about 21%. Conclusion Movement derived from did not align locations intensity model. This finding suggests that might have tendency overestimate resistance low suitability. Therefore, may adequately capture individual decisions selection movement. To protect linking habitat, data on data) can be coupled better understand movements populations as consequence features.
