How do different processes of habitat fragmentation affect habitat quality? – Evidence from China

Large-scale loss and fragmentation of natural habitats is one the critical factors in global decline biodiversity. Habitat quality foundation for supporting biodiversity, so exploring mechanisms by which habitat affects important biodiversity protection. However, little known about specific forms that various processes affect quality. Taking China as an example, three (the decrease area, increase isolation, edge) variations were quantitatively assessed from 2000 to 2020. On this basis, Pearson coefficients, Generalized Additive Model (GAM) Geographical detector employed examine linear\non-linear\combined impacts different on The results indicated there was a clear trend degradation 2000–2020. 56.94%, 42.33%, 50.89% area experienced edge, respectively, 63.12% All these result downward form showed non-linear characteristics. isolation consistently had significant negative influence quality, albeit with varying strengths at segments. While edge causes overall two have more complex relationship, response curves varied between positive correlations. In addition, are exacerbated when multiple occur simultaneously. These findings reveal inform development rational landscape planning conservation measures China.

Disturbance‐mediated community characteristics and anthropogenic pressure intensify understorey plant invasions in natural forests

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(8), P. 1856 - 1871

Abstract Although disturbance is considered a major driver of plant invasions across many systems, our understanding the mechanisms by which mediates understorey in natural forests limited. We used national forest inventory dataset spanning New Zealand's wide climatic and soil fertility gradients to disentangle disturbance‐mediated community characteristics driving abundance, species richness functional composition invasions. Disturbance‐mediated declines canopy tree abundance increases pH increased non‐native cover relative co‐occurring native assemblages. Cover also with proximity anthropogenic land cover. Non‐native assemblages had higher community‐weighted mean (CWM) values for specific leaf area (SLA) but lower CWM height woodiness irrespective disturbance. However, greater nearby drove decreased Synthesis : Our study provides first national‐scale evidence that effects on properties increase both plants understories. revealed trait differences between (SLA particular), could alter fundamental ecosystem processes like litter decomposition nutrient cycling. Finally, landscape‐scale impacts may exacerbate increasing favouring woody invaders, achieve dominance future communities over longer‐term.

Integrating Entropy Weight and MaxEnt Models for Ecotourism Suitability Assessment in Northeast China Tiger and Leopard National Park

Land, Journal Year: 2024, Volume and Issue: 13(8), P. 1269 - 1269

Published: Aug. 12, 2024

The development of ecotourism in protected areas faces the challenge balancing conservation and ecotourism. Ecotourism suitability assessments are essential tools for managing tourism these areas. However, current often overlook biological factors, leading to adverse effects on wildlife. This study uses Northeast China Tiger Leopard National Park as a case establish comprehensive assessment system that integrates with tiger leopard habitat suitability, thereby linking wildlife conservation. primary research methods include analysis based entropy weight method using MaxEnt model. Based zoning results map was produced. indicates very high account 45.62% total area, covering approximately 6152.563 km2, primarily located edges village clusters. These can be prioritized developing infrastructure. balance conservation, contributing significantly coordinated economic, social, environmental objectives.
