Abstract:
... In this paper, the effect of diffusion on pattern selection in a predator-prey model with Michaelis–Menten type predator nonlinear harvesting is investigated. From the analysis of stability and bifurcation, the stability of the positive equilibrium and the occurrence conditions for the Hopf bifurcation, as well as the Turing instability, are obtained. Consequently, different patterns will occur in ...

Abstract:
... This paper presents research on recreational paddlefish anglers’ preferences for catch-and-release fishing. We used stated preference (SP) data from a choice experiment to identify the effect of a hypothetical catch-and-release regulation on fishing preferences, and revealed preference (RP) data to measure the desirability of actual paddlefish fishing locations. We then modeled the effects of catc ...

Abstract:
... Fog harvesting is a useful technique for obtaining fresh water in arid climates. The wire meshes currently utilized for fog harvesting suffer from dual constraints: coarse meshes cannot efficiently capture microscopic fog droplets, whereas fine meshes suffer from clogging issues. Here, we design and fabricate fog harvesters comprising an array of vertical wires, which we call “fog harps”. Under co ...

Abstract:
... The ‘tragedy of the commons’ has been investigated for several decades. At its centre is the question whether a common resource will collapse under over-exploitation. The isolated analysis of one resource has many conceptual benefits, yet in reality resources and welfare are intertwined. In this paper, we investigate a situation where a resource which is exploited for profit has the additional fea ...

Abstract:
... Intertidal limpets are subject to harvesting pressure in regions, e.g. oceanic islands, where marine organisms are a more accessible source of protein. These molluscs are very sensitive to human exploitation which often results on a decrease of their densities and an over-representation of immature individuals, because of the loss of large-sized reproductive specimens. Two species of exploited lim ...

Private forests in Europe are increasingly characterised by fragmented ownership and declining owner knowledge and engagement, raising concerns about the harvesting behaviour of private forest owners. The formation of forest owner groups is seen as a means not only of addressing fragmented ownership but also owner knowledge. It is also increasingly recognised that owner engagement is not only infl ...
