RESUMO:

Changes in landscape attributes lead to habitat loss which is the decrease in the amount of native vegetation area available for species to survive and persist in the landscape. Given this scenario, the objective of this paper is to investigate the effect of habitat loss on abundance, extinction, body condition and functional traits of small mammals along a gradient of fragmented landscapes. Our results show that habitat loss affects small mammal populations, leading to population declines until they reach an extinction threshold. This effect was most evident for T. pachyurus who is a habitat specialist who had both its abundance and occurrence affected as well as his body condition. In this sense, this result supports the idea that habitat specialists deserve special attention when it comes to conservation. Of the four morphological characteristics (tail, paw, ear and muzzle) we did not find significant relationship of the landscape on these characteristics, for any species according to the model prediction. Even though we did not find such clear effects for some variables, others were already highly influenced due to the loss of the amount of vegetation cover. Thus, maintaining an area of 30% to 35% of vegetation cover can save a wide diversity of species and conserve various ecological processes essential for ecosystem functioning.
