Distribution Patterns and Ecological Determinants of Suitable Habitats for the Dhole (Cuon alpinus) in China

Animals, Journal Year: 2025, Volume and Issue: 15(4), P. 463 - 463

Published: Feb. 7, 2025

As a keystone predator within forest ecosystems, the dhole (Cuon alpinus) plays pivotal role in shaping population structure and dynamics of these biomes. In China, populations have experienced dramatic decline, primarily due to habitat loss fragmentation, poaching, other historical factors. However, distribution patterns suitable habitats key environmental factors influencing their suitability remained unclear. this study, we employed MaxEnt model assess for dholes across China. The results revealed that primary potential were mean diurnal range (Bio2), temperature seasonality (Bio4), minimum coldest month (Bio6), elevation. Potentially predominantly located central-western northwestern regions, with scattered distributions southeastern parts while areas high mainly concentrated region. proportion varied significantly among nine provinces analyzed. This study clarified identified constraints affecting findings provide critical ecological data support conservation management

Integrating ecological niche modeling and land use analysis for targeted conservation of Elaeocarpus prunifolius in India

Published: Oct. 29, 2024

Mismatch between broad spatial scales at which niche models operate vis-à-vis the finer localized required for conservation actions often hinder effective translation of model outputs into actionable strategies. This study addresses this issue by integrating ecological modelling (ENM) with land use and cover (LULC) analysis to improve status a threatened tree species Elaeocarpus prunifolius in Northeast India. Using Maximum Entropy (Maxent) model, we predicted potential distribution E. using MODIS-based Enhanced Vegetation Index (EVI) ASTER-based elevation data. The distribution, covering 8.97% (~ 201,321 ha) Meghalaya's total geographical area, was further refined through overlay LULC maps, identifying ~ 17,033 ha as highly suitable habitat. Field validation maps led discovery new populations, confirming accuracy. integrated approach demonstrates effectiveness combining ENM precise identification sites, thereby improving successful reintroduction efforts prunifolius. highlights critical role predictive ground developing informed

Avian Habitat Identification and Network Construction in Nanjing

Landscape Architecture, Journal Year: 2024, Volume and Issue: 31(12), P. 87 - 95

Published: Dec. 1, 2024

The accelerating pace of urbanization presents an escalating challenge to avian biodiversity, especially in densely populated regions where habitat loss, fragmentation, and environmental degradation have become pervasive. As urban areas expand, the displacement transformation natural habitats vital bird species led a marked decline diversity disrupted ecological equilibrium. Thus, restoration maintenance healthy stable ecosystems are imperative for safeguarding biodiversity cities. This research aims devise optimized strategy constructing networks, transforming isolated into interconnected cohesive network that fosters resilience. overarching objective is furnish planners conservationists with robust framework enhance through integrated scientifically grounded management initiatives. A systematic approach adopted optimize following structured process from identification "single habitats" assembly "comprehensive network". employs Maximum Entropy Model (MaxEnt) forecast identify suitable across landscape Nanjing, China. MaxEnt, known its effectiveness modeling distribution based on variables occurrence data, utilized generate suitability maps. These maps zones values exceeding 0.9, which subsequently designated as core areas, or "avian sources". sources represent most ecologically favorable environments serve focal nodes network. To spatial analysis, Morphological Spatial Pattern Analysis (MSPA) applied delineate patches at periphery. MSPA, landscape-level analysis tool, can enable key structural elements such corridors, islets, patches. Further, both Minimum Cumulative Resistance (MCR) model Circuit Theory construct network, evaluating connectivity between identified peripheral MCR facilitates least-cost pathways movement by incorporating resistance, while introduces probabilistic dimension, allowing multiple potential routes accounting stochastic nature dispersal. By integrating these models, develop improves mitigates fragmentation. MaxEnt reveals several highly particularly aquatic terrestrial intersect.
