Enter the 'nexus' of multiple resources, linked in turn to management and policy frameworks, and embedded in broader political processes. The nexus conceptually links multiple resource-use practices and serves paradigmatically to understand interrelations among such practices that were previously considered in isolation. Here we will demonstrate that resource recovery is at the core of operationalizing the nexus. This is fundamentally different from efficiency and productivity, although nexus practices can be seen in terms of deriving increased output from limited resources.
Conservation planning can be challenging due to the need to balance biological concerns about population viability with social concerns about the benefits biodiversity provide to society, often while operating under a limited budget. Here, we use a multi-attribute utility function to assess the optimal maternity roosts to conserve for maintaining the population viability and the ecosystem services of a single species, the Mexican free-tailed bat (Tadarida brasiliensis mexicana).
