“…The nature of defined aquatic pathways between freshwater sites provides a uniquely appropriate ecosystem for studying the incorporation of connectivity into different models. Our results support those found in other studies in ecosystems with less well‐defined pathways (Correa‐Ayram, Mendoza, Etter, & Pérez‐Salicrup, 2019; Václavík et al., 2012), and as such supports the call for more investigation into the relevance of connectivity parameters to species dispersal.…”

“…This low connectivity could be a consequence of different factors. The landscape between the northern and southern oak forest patches is dominated by plains in which extensive modification of the original vegetation has occurred; natural forests have been replaced with agricultural and cattle-raising areas and expanding urban infrastructure with dense population centers [49,66,67,104]. Taken together, these landscape modifications have restricted the movement of potential acorn dispersers, decreasing the levels of connectivity between oak forest patches [89,104].…”

Taken together, these landscape modifications have restricted the movement of potential acorn dispersers, decreasing the levels of connectivity between oak forest patches [89,104]. However, we detected that the connectivity changes between regions within the basin, pointing out the ecological vulnerability for some fragments due to the degree of isolation.…”

Connectivity is a landscape property that promotes gene flow between organisms located in different patches of habitat and provides a way to reduce habitat loss by maintaining flux of organisms through the landscape; it is an important factor for conservation decisions. In this study, we evaluated the structural and functional connectivity among 510 oak forest remnants in a basin in central Mexico by modeling the potential distribution of seven oak species that inhabit in it. The structural and functional connectivity of oak forest remnants was estimated by graph theory. Distribution models for all the oak species had a good level of predictability, showing that 53.16% of the basin is suitable for oaks. The importance for connectivity varied between the remnant forests. Large forest fragments had the highest values of connectivity, and small forest fragments acted as steppingstones favoring the movement of organisms among fragments. In the southern region of the basin, connected remnant forests had conformed to a large network, but in the northern region, the remnant forests were mostly isolated. Conservation of oak forests in this basin requires protection for remaining patches by preserving both large and small ones and restoring biological corridors to reduce the isolation of forest fragments.

“…Finally, LHFI can readily be used in landscape connectivity studies (Correa Ayram et al, 2017) to identify management priorities that integrate elements of the landscape (e.g. corridors, restored patches, among others) and encourage connectivity of multiple species (Correa Ayram et al, 2019). This approach is key for public policies that regulate land use in priority areas for ecosystem connectivity, as it is for deciding where to establish such areas to effectively achieve global conservation goals in the first place (e.g.…”

19The maintenance of biodiversity and the capacity of natural systems to provide goods and 20 services for people is affected on different levels by the intensity of human activities on 21 ecosystems. In this study, we apply a Legacy-adjusted Human Footprint Index (LHFI) to 22 evaluate the spatiotemporal variation of anthropic impact in Colombia in 1970, 1990, 2000 23 and 2015. We identified hotspots of change in LHFI and we evaluated the intensity of 24 anthropic pressures in natural regions and ecosystems. We found that LHFI in Colombia 25 increased between 1970 and 2015. The Andean and Caribbean regions presented the highest 26 levels of anthropic impact, remaining stable over time. Hotspots of change were mainly 27 located in the following regions: Andean (Antioquia, Cauca and Valle del Cauca states), 28 Amazon (Amazonas, parts of Meta, Guaviare and Putumayo states) and Orinoco (Casanare 29 and parts of Meta and Vichada states). In addition, ecosystems that under the IUCN 30 ecosystem risk categories are Critically Endangered (CR) and Vulnerable (VU) were the 31 most affected by a high level of human impact. Spatiotemporal evaluation of the human 32 footprint in Colombia provides new insights about trends in human pressures on ecosystems 33 and constitutes an analytical tool with high potential for harmonizing land use planning and 34 biodiversity conservation.35 36
