“…Currently, the implementation of dispersal corridors is the main strategy recommended by researchers and conservation managers to bolster threatened jaguar populations and to connect protected areas (e.g. Rabinowitz & Zeller, 2010;Rodríguez-Soto et al, 2013). Our study provides theoretical evidence for low jaguar persistence probabilities under metapopulation dynamics (Figure 4).…”

Habitat loss and fragmentation have serious consequences for long-term population persistence, thus we investigated the effects of these processes on jaguars (Panthera onca) across the species' distribution range. We employed theoretical simulations of population dynamics, making use of real and hypothetical landscapes to understand how landscape patterning affects the long-term persistence of species, and investigated the isolated and synergistic effects of habitat loss and fragmentation. Jaguar persistence probability was related both to the amount and pattern of landscape subdivision, but with a strong tolerance for habitat loss because the amount habitat could be between 230 to 5841 km 2. In contrast, the persistence probability of smaller jaguar populations decreased dramatically in fragmented landscapes, indicating that fragmentation is a greater threat to jaguar long-term viability than habitat loss. Only two of the 28 populations included in our study were deemed viable in the long-term. Given the increase in habitat fragmentation and the current threat status of the jaguar, we discuss the best strategies for their conservation.

“…7). Rodríguez-Soto et al (2013) suggested a minimum width of 14 km for viable corridors and a 2.5 km width for potential corridors for jaguar in Mexico. Both of the simulated scenarios with riparian forest for cougar were larger than 14 km, although it is possible that even they could not provide functional connectivity.…”

“…Both of the simulated scenarios with riparian forest for cougar were larger than 14 km, although it is possible that even they could not provide functional connectivity. For jaguar, the connectivity paths are narrower than 14 km and possibly a riparian forest larger than 30 m is needed to provide connectivity areas wide as Rodríguez-Soto et al (2013) suggested for jaguar in Mexico.…”

Strictly Protected Areas and riparian forests in Brazil are rarely large enough or connected enough to maintain viable populations of carnivores and animal movement over time, but these characteristics are fundamental for species conservation as they prevent the extinction of isolated animal populations. Therefore, the need to maintain connectivity for these species in human-dominated Atlantic landscapes is critical. In this study, we evaluated the landscape connectivity for large carnivores (cougar and jaguar) among the Strictly Protected Areas in the Atlantic Forest, evaluated the efficiency of the Mosaics of Protected Areas linked to land uses in promoting landscape connectivity, identified the critical habitat connections, and predicted the landscape connectivity status under the implementation of legislation for protecting riparian forests. The method was based on expert opinion translated into land use and land cover maps. The results show that the Protected Areas are still connected by a narrow band of landscape that is permeable to both species and that the Mosaics of Protected Areas increase the amount of protected area but fail to increase the connectivity between the forested mountain ranges (Serra do Mar and Serra da Mantiqueira). Riparian forests greatly increase connectivity, more than tripling the cougars' priority areas. We note that the selection of Brazilian protected areas still fails to create connectivity among the legally protected forest remnants. We recommend the immediate protection of the priority areas identified that would increase the structural landscape connectivity for these large carnivores, especially paths in the SE/NW direction between the two mountain ranges.

“…CorridorDesigner uses the least-cost path analysis to connect two patches of species occurrence (Rodríguez-Soto, et al, 2013). The ecological neighbourhood for averaging the habitat suitability model was set to 50 m (Bright & Morris, 1992) to account for edge effects and the perceptual range of M. avellanarius.…”
