Fine roots mediate plant nutrient acquisition and growth. Depending on soil nutrient availability, plants can regulate fine root biomass and morphological traits to optimise nutrient acquisition. Little is known, however, about the importance of these parameters influencing forest functioning. [...]

(1) Background: Southern Amazonia encompasses some of the most human-impacted and deforested regions of South America, resulting in a hyper-fragmented landscape. In this context, by using a geometric morphometrics approach, we aimed to examine the effect of forest fragmentation on developmental instability (DI) of the mandible, assessed by variation of fluctuating asymmetry (FA), in four neotropical small mammal species inhabiting the municipality of Alta Floresta (Brazil).

Supporting small farmer livelihoods in fragile, biodiverse regions, such as tropical forests, is a priority for many development agencies and national governments. These regions tend to be characterized by recent human settlements, increasing populations and infrastructure development, as well as competitive land use activities, which exert pressure on fragile ecosystems.
