Ecological sustainability has recently risen to prominence in scientific research and management applications. Approaches measuring ecological connectivity their application optimize network (EN) design are powerful tools against landscape fragmentation biodiversity loss. We focused on building an EN by identifying the most sensitive areas for within Reggio Calabria (Italy) metropolitan area. also proposed a defragmentation scenario improve obtained EN.

Using simulation modeling to demonstrate the performance of graph theory metrics and connectivity algorithms

Journal of Environmental Management, Journal Year: 2024, Volume and Issue: 352, P. 120073 - 120073

Models and metrics to measure ecological connectivity are now well-developed widely used in research applications mitigate the impacts of climate change anthropogenic habitat loss. Despite prevalent application models, however, relatively little is known about performance these methods predicting functional patterns organism movement. Our goal this paper was compare different models their abilities predict a wide range simulated animal movement patterns. We Pathwalker software evaluate several model predictions based on graph theory, resistant kernels, factorial least-cost paths. In addition, we assessed efficacy synoptic patch-based approaches defining source points for analysis. total, produced 28 simulations As expected, found that choice variable most influenced prediction accuracy. Moreover, kernels approach consistently provided strongest correlations underlying processes. The results also suggested agent-based simulation itself can often be best analytical framework map conservation applications, given its biological realism flexibility implement combinations mechanism, dispersal threshold, directional bias, destination bias spatial composition locations doing so, provide novel insights guide future analyses. research, could use same species groups see how reliability depends analyzed. This bring light other elements play an essential role connectivity.

Current national nature reserves are insufficient to safeguard the long-term survival of birds and mammals in China

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: June 7, 2024

Abstract Enhancing the connectivity of protected areas is a global consensus for conserving biodiversity. Yet, it unclear whether habitats are sufficiently connected within to efficiently protect wildlife populations long-term survival. Here we show that, in general, China’s national nature reserves can effectively about one-half bird and mammal However, they only 25% birds 13% terrestrial mammals with high motility. Areas low conservation effectiveness highly overlapped small size intensity human activity. Artificial landscapes (arable land built-up land), which account less than 2% area areas, disproportionately cause nearly 40% loss. The results suggest that maintaining levels functional as important or networks. Our findings have implications improving management China beyond.

An overview of computational tools for preparing, constructing and using resistance surfaces in connectivity research

Landscape Ecology, Journal Year: 2022, Volume and Issue: 37(9), P. 2195 - 2224

Published: Aug. 1, 2022

Abstract Context Connectivity between habitat patches is a recognized conservation action to conserve biodiversity in rapidly changing world. Resistance surfaces, spatial representation of cost movement across the landscape, are often foundation for connectivity analyses but working with them can be daunting due diversity and complexity software tools. Objectives We present an overview steps involved when resistance identify tools that perform specific tasks, evaluate user experience tools, needs community, some recommendations users developers. Methods identified applicable at each three (i) preparing data, (ii) constructing optimizing (iii) using surfaces. conducted online survey community assess popularity on five criteria characteristics important selection Results reviewed total 43 which 10 useful data preparation, 27 allow construction, 30 use A 148 participants 40 countries were familiar 37 Tools ranked heterogeneously criteria.

Biodiversity Conservation in Human‐Dominated Landscapes: Toward Collaborative Management of Blue–Green Systems

Conservation Letters, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 1, 2025

ABSTRACT Maintaining ecological connectivity is crucial for biodiversity, yet effectively managing interconnected areas through actor collaboration challenging. This study examines social–ecological fit in aquatic “blue” and terrestrial “green” areas, encompassing natural semi‐natural elements, human‐dominated landscapes. Combining species distribution models analyses focused on declining amphibians survey data actors’ area management within we create a spatially explicit network that analyze using models. Results highlight diverse dependencies shaping interactions. Strong observed blue‐rural‐green whereas blue‐urban‐green lack collaboration, with minor rivers urban‐green spaces at the network's core plagued by misfit. Strengthening these essential to prevent further degradation. Incorporating perspective covering blue green guides targeted interventions fosters effective conservation policy practice.

Makurhini: An R package for comprehensive analysis of landscape fragmentation and connectivity

Published: April 9, 2025

Habitat loss, fragmentation, and climate change threaten biodiversity, emphasizing the need to maintain landscape connectivity for species movement access resources. Limited conservation funds land-use conflicts make prioritizing efficient measures essential. To address this, we developed Makurhini R package, an open-source tool systematically calculating key fragmentation metrics. provides powerful, integrated analyses efficiently processes large datasets with parallel processing, accommodating diverse contexts. Key features include computing metrics, characterizing links using Euclidean, least-cost, circuit theory approaches, evaluating indices such as Probability of Connectivity (PC) Equivalent Connected Area, ranking patches by their contribution connectivity. Case studies in Mexico, Colombia, Spain demonstrate its applicability. offers a robust, data-driven framework support restoration fragmented landscapes.
