“…One of the primary steps in corridor modeling is to develop a travel‐cost resistance surface based on the key environmental variables which influence travel effort, thereby quantifying the expected difficulty the target species encountered in traversing the landscape (Zeller et al, 2012). There are various approaches available to optimize resistance surfaces, including but not limited to expert opinion (Dutta et al, 2016; Rathore et al, 2012), habitat suitability (Balbuena‐Serrano et al, 2022; González‐Saucedo et al, 2021), movement patterns (Carvalho et al, 2016; Proctor et al, 2015), genetic data (Dutta et al, 2022; Jennings et al, 2020), or combinations of these methods (Zeller et al, 2018; Ziółkowska et al, 2016). A resistance surface is generally developed by using empirical data on species distribution or movement in combination with key environmental and anthropogenic variables that may influence the movement of the species (Hilty et al, 2019; Wade et al, 2015).…”

“…We rescaled these predicted movements to between 0 and 1 to represent the landscape's permeability to mammal movement across the globe. We then used an inverse linear function (e.g., 1-permeability) to convert the permeability surface to a resistance-to-movement surface [52][53][54] . Following other studies, we further modified resistance-to-movement, M, by percent slope to reflect the energetic costs of moving in steep terrain 28,50,55 using the equation = ( ) , where s = terrain slope.…”

Rapid environmental change threatens to isolate the world's wildlife populations and intensify biodiversity loss. Global policies have called for expanding and connecting the world's protected areas (PAs) to curtail the crisis, yet how well PA networks currently support wildlife movement, and where connectivity conservation or restoration is most critical, have never been mapped globally. Here, we map the functional connectivity (how animals move through landscapes) of the world's terrestrial PAs for the first time. Also, going beyond existing global connectivity indices, we quantify national PA-connectedness using an approach that meaningfully represents animal movement through anthropogenic landscapes. We find that reducing the human footprint may improve national PA-connectivity more than adding new PAs; however, both strategies are critical for improving and preserving connectivity in places where the predicted flow of animal movement is highly concentrated. We show that the majority of critical connectivity areas (CCAs) (defined as globally important areas of concentrated animal movements) remain unprotected. Of these, 72% overlap with previously-identified global conservation priority areas, while 3% of CCAs occur within moderate to heavily modified lands. Conservation and restoration of CCAs could safeguard connectivity of the world's PAs, and dovetail with previously identified global conservation priorities.

“…Los Ojos is nested within other properties owned by Cuenca de los Ojos, A.C. (i.e., Cuenca Los Ojos) in the Madrean Archipelago and is a conservation priority corridor (González‐Saucedo et al 2021) connecting the Sky Islands of the Chiricahua, Peloncillo, and Animas mountains in the United States and the Sierra Madre Occidental mountain range in Mexico. The 100‐km 2 study site was directly south of the Federal Highway 2 expansion project and included riparian canyons of oak ( Quercus spp.)…”

Mammal use of riparian corridors in semi‐arid Sonora, Mexico

et al. 2022

Wildlife populations in semi‐arid regions are increasingly challenged by human activities and dependent on the connectivity of riparian corridors for access to surface water. The Madrean Archipelago is a biodiversity hotspot along the arid United States–Mexico borderlands that support both Neotropical and Nearctic wildlife. Infrastructure development (e.g., the border wall and the expansion of Mexican Federal Highway 2) in this region inhibits wildlife movement along the transnational mountain archipelago by disconnecting habitat. To explore the relationship between habitat variables and mammal use of riparian corridors in northern Sonora, Mexico, we collected data from 19 motion‐sensitive cameras between October 2018 and April 2019 and used single‐season occupancy models and Royle‐Nichols abundance estimation models to analyze our data. We recorded 21 species of mammals, including the first sighting of jaguar (Panthera onca) in this region in 25 years. River characteristics (distance from river, riparian corridor width, water availability), remoteness (distance from highway, productivity, elevation), and topographic variety (vertical elevation difference) influenced patterns of occupancy probability and estimated abundance of mammals >1 kg, but the strength and direction of these relationships varied by species. Additionally, intermittently wet desert washes were comparable in species richness to the perennial system. These results highlight the importance of examining physical and biological aspects of habitat. This is especially true when identifying corridors where mitigation structures should be placed to improve wildlife connectivity in biodiversity hotspots like the Madrean Archipelago and semi‐arid ecosystems worldwide.
