The establishment of ecological networks is crucial for biodiversity conservation, especially at broad spatial scales. It still challenging to develop an network construction method based on landscape connectivity multiple species. purpose this study propose a multi-species framework approach constructing and determine the restoration priority four focal mammal species across protected areas in western mountains Henan Province, China. We built each by using circuit theory least-cost path models, integrated corridors key barrier results showed that was closely related dispersal capacity. For with higher capacity, all core were interconnected have alternative paths, seemed be well connected. With decline ability, became more complex not connected, migration exceed capability emerged. important consider needs species-specific management plans. Key areas, which significant impacts migration, are mainly land use dominated cropland. Our research indicates methods proposed can help may facilitate conservation efforts species, poor distribution movement data.

Differences in mammal community response to highway construction along a small urban–rural gradient

Wildlife Biology, Год журнала: 2025, Номер unknown

Опубликована: Март 4, 2025

Worldwide, transportation agencies have been involved in road mitigation efforts to reduce mortality and promote connectivity of endangered species. Baseline data on how mammals respond highway construction, however, are rarely collected monitoring studies, including the USA. Our goal this study was assess differences response mammal community construction along a gradient human land use (HLU) from July 2019 November 2020 southern Texas, We compared species composition terrestrial at five sites before during assessed diel activity for seven different HLU levels between these two time periods. found that lower period each level. There were greater pre‐construction periods as decreased. Community diversity greatest areas with low level HLU, followed by medium high levels, more carnivores, large ungulates, rodents sites. For many species, patterns across all reflected higher period. shows behavior (diel activity) likely change regardless degree HLU. These results may influence scientists consider potential impacts wildlife affect their attempt mitigate impacts.

Anthropogenic, environmental and temporal associations with vertebrate road mortality in a wildland–urban interface of a biodiverse desert ecoregion

Royal Society Open Science, Год журнала: 2024, Номер 11(7)

Опубликована: Июль 1, 2024

Road mortality adversely affects wildlife populations. As urbanization and infrastructure densities expand, transportation management aim to mitigate wildlife–vehicle conflicts while conserving biodiversity. Roadways in aridland ecosystems can invariably impact differently from temperate other biomes, yet these rapidly urbanizing regions are understudied as urban–rural gradients. We conducted road-cruise surveys ( n = 204; 2018–2023) assess anthropogenic, environmental, temporal factors associated with vertebrate roadkill across the wildland–urban interface of Arizona’s biodiverse Sonoran Desert ecoregion—already subjected increased human development climate change. Of 2019 vertebrates observed, 28.5% were roadkill. Increasing levels reduced abundance on roads road-killed endothermic vertebrates. Traffic volume was strongly roadkill; additive effects began at approximately 20 vehicles. Daily low temperature and/or relative humidity also groups. provide empirical evidence understand wildlife–roadkill associations expanding interfaces inform effective mitigation conservation strategies regions. recommend that managers or avoid rural areas possess high biodiversity, valuable waterways migration corridors, populations vulnerable species.

A multivariate approach to assessing landscape structure effects on wildlife crossing structure use

Ecological Processes, Год журнала: 2024, Номер 13(1)

Опубликована: Окт. 4, 2024

Abstract Background Complexity in landscape structure is often assessed using individual metrics related to ecological processes. However, this rarely incorporates important relationships among and may miss effects. Multivariate statistics provide techniques for assessing overall We how multivariate could be used connect with an process [bobcat ( Lynx rufus ) wildlife crossing (WCS) use]. tested at WCS sites compared the surrounding affected detections sites. Our study was conducted Cameron County, Texas, USA where WCSs are various stages of construction monitoring. a classified land use/land cover map aerial LiDAR calculate configuration density random created indices principal components analysis assess effects on camera trap WCSs. Results Landscape did not differ from locations. Wildlife use increased greater woody decreased increasing vegetation density. allowed identification differences impacted use. Ordination methods helped identify contributions effect. Conclusions structures permanent fixtures landscapes, so selecting appropriate locations broad-scale likely increases target species Using provides planners more holistic approach placement comprehensive picture pattern relationships.

Examining the Spatial Structure of Woody Cover Within a Highway Road Effect Zone for Ocelots in Texas

Abstract Assessment of locations where wildlife species cross highways is a key question in mitigating future wildlife-vehicle mortality. Examination the spatial structure, complexities, and patterns vegetation or other land-use types (i.e., cropland, urban areas) near roadways allows scientists to identify any thresholds that influence animals are likely die successfully roadway. We used historic 1982 2017 dataset ocelot ( Leopardus pardalis ) mortality approximate road crossing telemetered ocelots Lower Rio Grande Valley Texas examine structure woody within hypothesized effect zone. determined if there were differences cover 1050 m buffer each successful roadkill location using PERMANOVA principal component analyses. similarity percentages analysis determine relative contribution aspect on locations. found statistically significant attributes patches at versus 150 extent (pseudo-F 1,41 = 4.85, P(perm) 0.008, permutations 9949). Largest patch index contributed most between (15.94%), followed by mean area (15.44%), percent (15.18%), aggregation indices (14.53%), Euclidean nearest neighbor (13.47%), edge (13.08%) densities (12.36%).

Human activities have led to the fragmentation of wilderness landscapes, posing a significant challenge biodiversity conservation. areas and assessing their network connectivity are foundational for devising conservation strategies address landscape fragmentation. Methods: This study focuses on Zhejiang Province, which is under intense urbanization pressure in China. It employs Boolean recognition multi-criteria evaluation (MCE) delineate areas. By reassessing indicator system its weights, evaluates Zhejiang. The results displayed: (1) In large proportion area still maintains good integrity. (2) can encompass 32.5% highly fragmented habitats currently unallocated potential natural reserves. (3) where species movement frequent but not yet designated as protected, maps been created, networks could play crucial role. findings provide basis enhancing nature reserves promoting rewilding ecological restoration specific areas, offering quantitative support future management oriented towards
