Environmental insecurity is a source and outcome of biodiversity declines and social conflict. One challenge to scaling insecurity reduction policies is that empirical evidence about local attitudes is overwhelmingly missing. We set three objectives: determine how local people rank risk associated with different sources of environmental insecurity; assess perceptions of environmental insecurity...
Madagascar's flora and fauna are remarkable both for their diversity and supraspecific endemism. Moreover, many taxa contain large numbers of species with limited distributions. Several hypotheses have been proposed to explain this high level of microendemism, including 1) riverine barrier, 2) mountain refuge, and 3) watershed contraction hypotheses, the latter 2 of which center on fragmentatio...
In this issue of Neuron, Harwell et al. (2012) identify a new role for the secreted molecule Shh and its receptor Boc in synapse formation. These results add an unexpected new player to the expanding list of extracellular cues regulating the spatial specificity of synapse formation.
