Habitat species and old growth trees are more vulnerable to logging as access is improved. The birds that nest in their crevices, the epiphytes that hang from their branches and the invertebrates in the leaf litter are all adversely affected and biodiversity is reduced. Habitat fragmentation can be ameliorated to some extent by the provision of wildlife corridors connecting the fragments. These can be a river, ditch, strip of trees, hedgerow or even an underpass to a highway. Without the corridors, seeds cannot disperse and animals, especially small ones, cannot travel through the hostile territory, putting populations at greater risk of
Long-tongued arboreal mouse Long-tongued arboreal mouse The long-tongued arboreal mouse ("Rhagomys longilingua") is a South American rodent species of the family Cricetidae. It is found in a variety of habitats, including dense forest, in Bolivia and Peru at elevations from on the eastern side of the Andes. The species is at least partly arboreal. It is distinguished from the Brazilian arboreal mouse ("R. rufescens"), the only other known member of "Rhagomys", by spiny fur and certain skull features such as the presence of beading in the interorbital region. The adult long-tongued arboreal mouse weighs in the range and has a tail that is
