摘要: Abstract 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 species’ distribution range. We employed theoretical simulations dynamics, making use real hypothetical landscapes to understand how landscape patterning affects persistence species, isolated synergistic habitat fragmentation. Jaguar probability was related both amount pattern subdivision, but with a strong tolerance because could be between 230 5841 km 2 . In contrast, smaller jaguar populations decreased dramatically in fragmented landscapes, indicating that is greater threat viability than loss. Only two 28 included our study were deemed viable long-term. Given increase current status jaguar, discuss best strategies their conservation.
