Increasing urbanization degrades quantity, quality, and the functionality of spatial cohesion natural areas essential to biodiversity ecosystem functioning worldwide. The uncontrolled pace building activity erosion blue (i.e., aquatic) green terrestrial) landscape elements threaten existing habitat ranges movability wildlife. Local scale measures, such as nature-inspired engineered Blue-Green Infrastructure (BGI) are emerging mitigation solutions. Originally planned promote sustainable stormwater management, adaptation climate change improved human livability in cities, instruments offer interesting synergies for support ecological infrastructure. BGI especially appealing globally declining amphibians, a rich diverse vertebrate assemblage sensitive urbanization. We integrated biological highly resolved urban-rural land-cover data, ensemble models suitability, connectivity based on circuit theory improve multi-scale multi-species protection core habitats corridors Swiss lowlands. Considering broad spectrum amphibian biodiversity, we identified distributions hotspots four at regional scale, namely i) forest edges, ii) wet-forest habitats, iii) soils with variable moisture iv) riparian zones. Our work shows that cities can make substantial contribution (e.g., up 15% urban space study area) wider connectivity. highlight importance planning locally strategic locations across peri-urban permeability availability 'stepping stone' densely populated landscapes, maintenance thereby enhancing functioning.

Identifying priority core habitats and corridors for effective conservation of brown bears in Iran

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Abstract Iran lies at the southernmost range limit of brown bears globally. Therefore, understanding habitat associations and patterns population connectivity for in is relevant species’ conservation. We applied species distribution modeling to predict suitability identify core areas corridors. Our results showed that forest density, topographical roughness, NDVI human footprint were most influential variables predicting bear distribution. The crucial corridor networks are concentrated Alborz Zagros Mountains. These two predicted be fragmented into a total fifteen isolated patches if dispersal across landscape limited 50,000 cost units, aggregates capable dispersing 400,000 units. found low overlap between corridors, habitats with protected areas, suggesting existing area network may not adequate conservation Iran. suggest effective requires protection both corridors them, especially outside Iran’s areas.

A multi-species approach for protected areas ecological network construction based on landscape connectivity

Global Ecology and Conservation, Journal Year: 2023, Volume and Issue: 46, P. e02569 - e02569

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.

PLoS ONE, Journal Year: 2018, Volume and Issue: 13(11), P. e0206071 - e0206071

Many large-scale connectivity initiatives have been proposed around the world with aim of maintaining or restoring to offset impacts on biodiversity habitat loss and fragmentation. Frequently, these are based requirements a single focal species concern, but there is growing attention identifying for multi-species assemblages. A number methods modelling developed; likewise, different approaches used construct resistance surfaces, basic input data analyses. In this study we modelled group vertebrates representative heavily fragmented forests in north-central Victoria, Australia. For each species, least-cost compared two alternate distribution models expert opinion, respectively. We integrated results across individual obtain map region. surface assessment relative use land-cover classes by target was more informative than one models. The former resulted pathways strongly aligned existing patches strips native vegetation. region, streams their associated riparian vegetation relatively high ecological potential feasibility contribute regional assemblage forest vertebrates.

Abstract Connectivity conservation is aimed at sustaining animal movements and ecological processes important to ecosystem functioning the maintenance of biodiversity.
