Using stepping-stone theory to evaluate the maintenance of …
2021年5月10日 · In this study, we classified the absence of stepping-stone protection based on stepping-stone area, distribution, and potential loss and identified key stepping-stone categories in urgent need of ECL protection, which will be useful for delineating the ecological red line in …
Incorporating barriers restoration and stepping stones …
2024年9月1日 · In barriers restoration schemes, redundant corridors were reduced and connectivity enhancement effects were optimal when restoring the highest and higher level barriers. In stepping stones schemes, establishing natural patches near the midpoint of longer corridors as stepping stones avoided ecological traps and enhanced landscape connectivity best.
Stepping Stone Strategy: A Cost-Effective Way to Address Habitat ...
2023年6月5日 · We propose a stepping stone strategy (SSS) to deal with habitat fragmentation threatening an endangered primate, the black-and-white snub-nosed monkeys (Rhinopithecus bieti). We selected the southern range of R. bieti as the study area, which covers 3,580 km 2.
Assessment of risks to habitat connectivity through the stepping-stone …
2022年5月1日 · In this study, potential ecological corridors and stepping stones under ecological security patterns with different connectivity levels were identified according to the important habitats and resistance surfaces.
2.7 Stepping Stones and Gaps - US Forest Service
For visually-orientated species, gap thresholds may be determined by the ability to see the next stepping stone or across the gap. In riparian corridors, restore gaps in higher order streams first to provide the greatest benefit for biodiversity.
Stepping stone corridors are relatively small patches of native vegetation scattered throughout a landscape that can provide some connectivity for a variety of species. As with all corridors, stepping stones can exist at a variety of scales ranging from single trees to patches covering some hectares. Stepping stones in some studies
Small patches can serve as stepping stones, allowing for species movement between large patches and are important in fragmented landscapes. However, the loss of a stepping stone can often inhibit movement, increasing patch isolation.
The matrix enhances the effectiveness of corridors and stepping stones
2004年10月1日 · Using an herbivore-host-plant system consisting of the planthopper Prokelisia crocea and its sole host plant, prairie cordgrass (Spartina pectinata), we show that the effectiveness of corridors...
Assessment of risks to habitat connectivity through the stepping-stone …
2022年5月1日 · We identified potential corridors and stepping stones connecting important habitats in Shenzhen, China. Then, an SVM was used to evaluate the development probability of each small patch and analyze the factors affecting this probability.
Creating Effective Urban Greenways and Stepping-stones: Four …
2018年9月27日 · This review describes the effectiveness of corridor and stepping-stone strategies, actions that could enhance their ability to support animal movement, and the state of knowledge on connectivity planning, implementation, and outcomes.
