Abstract Introduction Habitat fragmentation is one of the major causes loss biodiversity that our planet experiencing. This has affected ecosystems functioning and, consequently, provision ecosystem services (ES). Therefore, European Commission, in a 2013 communication, established concept Green Infrastructure (GI), which strategically planned network multifunctional areas with aim protecting and ES supply, as well improving ecological connectivity. Ecological restoration an essential element to achieve objectives GI, if targeted, could reverse widespread degradation improve landscape Objective In this study, we propose methodology prioritise restore by identifying GI Urdaibai Biosphere Reserve (UBR), north Iberian Peninsula, where forest plantations exotic species abound. Methods order identify elements (core corridors) integrated multispecies approach based on movement key ES-based multifunctionality. Subsequently, identified sectors connectivity particularly vulnerable (pinch points) using circuit theory. Thus, around pinch points were prioritised for future plans depending their aim: (1) Improve corridors high importance low quality (2) approach, (3) movement.

Meta‐replication, sampling bias, and multi‐scale model selection: A case study on snow leopard (Panthera uncia) in western China

Ecology and Evolution, Journal Year: 2020, Volume and Issue: 10(14), P. 7686 - 7712

Published: July 1, 2020

Abstract Replicated multiple scale species distribution models (SDMs) have become increasingly important to identify the correct variables determining and their influences on ecological responses. This study explores multi‐scale habitat relationships of snow leopard ( Panthera uncia ) in two areas Qinghai–Tibetan Plateau western China. Our primary objectives were evaluate degree which relationships, expressed by predictors, scales response, magnitude effects, consistent across or locally landcape‐specific. We coupled univariate optimization maximum entropy algorithm produce multivariate SDMs, inferring relative suitability for ensembling top performing models. optimized SDMs based average omission rate ensembles’ overlap with a simulated reference model. Comparison highlighted landscape‐specific responses limiting factors. These dependent effects hydrological network, anthropogenic features, topographic complexity, heterogeneity landcover patch mosaic. Overall, even accounting specific local differences, we found general landscape attributes associated requirements, consisting positive association uplands ridges, aggregated low‐contrast landscapes, large extents grassy herbaceous vegetation. As means performance bias correction methods, explored three datasets showing range intensities. The corrections depends intensity; however, density kernels offered reliable strategy under all circumstances. reveals response leopards environmental confirms role meta‐replicated designs identification spatially varying Furthermore, this makes contributions ongoing discussion about best approaches sampling correction.

Habitat suitability and connectivity implications for the conservation of the Persian leopard along the Iran–Iraq border

Ecology and Evolution, Journal Year: 2021, Volume and Issue: 11(19), P. 13464 - 13474

Abstract Habitat fragmentation has major negative impacts on wildlife populations, and the connectivity could reduce these impacts. This study was conducted to assess habitat suitability structural of Persian leopard along Iran–Iraq border (i.e., Zagros Mountains) compare situation identified core habitats with existing conservation areas (CAs). An ensemble modeling approach resulting from five models used predict suitability. To identify corridors border, factorial least‐cost path analyses were applied. The results revealed that topographic roughness, distance CAs, annual precipitation, vegetation/cropland density, rivers most influential variables for predicting occurrence in area. By an estimated dispersal 82 km (suggested by previous studies), three (two cores Iran one Iraq). largest located south center area, which had highest priorities. maintained within Iraqi side. Only about one‐fifth detected relative protected CAs Detected this be appropriate road map accomplish network regarding conservation. Establishing transboundary particularly is strongly recommended conserve large carnivores, including leopard.

Combining multiscale niche modeling, landscape connectivity, and gap analysis to prioritize habitats for conservation of striped hyaena (Hyaena hyaena)

PLoS ONE, Journal Year: 2022, Volume and Issue: 17(2), P. e0260807 - e0260807

Published: Feb. 10, 2022

Identifying spatial gaps in conservation networks requires information on species-environment relationships, and prioritization of habitats corridors. We combined multi-extent niche modeling, landscape connectivity, gap analysis to investigate scale-dependent environmental identify core corridors for a little-known carnivore Iran, the striped hyaena (Hyaena hyaena). This species is threatened Iran by road vehicle collisions direct killing. Therefore, understanding factors that affect its habitat suitability, pattern distribution, connectivity among them are prerequisite steps delineate strategies aiming at human-striped co-existence. The results showed highest predictive power extent was obtained sizes 4 2 km, respectively. Also, revealed number changed with increasing dispersal distance, approximately 21% found support 15-17% overlapped areas. Given body size species, mobility, lack significant specialization we conclude this would be more strongly influenced changes amount rather than configuration. Our approach scale variables ability must accounted efforts prioritize corridors, designing could facilitate through identification habitats, establishment areas, mitigating conflicts

Predicting wildlife corridors for multiple species in an East African ungulate community

PLoS ONE, Journal Year: 2022, Volume and Issue: 17(4), P. e0265136 - e0265136

Published: April 5, 2022

Wildlife corridors are typically designed for single species, yet holistic conservation approaches require suitable multiple species. Modelling habitat linkages wildlife is based on several modelling steps (each involving choices), and in the case of multi-species corridors, an approach to optimize species few or a functional corridor To model robust simultaneously evaluate impact methodological choices, we develop multi-method delineate that effectively capture movement while limiting area required. Using presence data collected along ground-based line transects between Lake Manyara Tarangire National Parks, Tanzania, assessed species-habitat association both ensemble stacked distribution frameworks used these estimate linearly non-linearly scaled landscape resistances seven ungulate We evaluated suitability least-cost circuit theory-based connectivity models each individually generated corridor. Our results revealed relationships subsequent differed across but pattern predicted study was similar all regardless method (circuit theory least-cost) scaling suitability-based cost surface (linear non-linear). Stacked were highly correlated with outputs (r = 0.79 0.97), having greatest overlap individual model: 61.6%; non-linear 60.2%). Zebra best single-species proxy connectivity. Overall, show achieve relatively low cumulative costs savanna ungulates as compared their respective corridors. Given challenges involved acquiring parameterizing zebra may act this system.
