Isolated Refuges for Surviving Global Catastrophes
A variety of global catastrophes threaten the survival of human civilization. For many of these catastrophes, isolated refuges could keep some people alive and enable them to rebuild civilization in the post-catastrophe world. This paper examines the potential importance of refuges and what it would take to make them succeed. The successful refuge will have a variety of qualities, including iso...
متن کاملEffects of prey refuges on a predator-prey model with a class of functional responses: the role of refuges.
In this paper, the effects of refuges used by prey on a predator-prey interaction with a class of functional responses are studied by using the analytical approach. The refuges are considered as two types: a constant proportion of prey and a fixed number of prey using refuges. We will evaluate the effects with regard to the local stability of the interior equilibrium point, the values of the eq...
متن کاملCoral reef fishes exploit flow refuges in high-flow habitats
Behaviour can offset the limitations of the morphology and physiology of a species to profoundly influence patterns of resource use. In fishes, flow refuging is a behavioural mechanism that may facilitate the occupation of turbulent, high-flow habitats by reducing extreme environmental demands on their swimming capabilities. Using a novel combination of experimental and field techniques, we exa...
متن کاملFacilitating Forgiveness
Feeling hurt, let down, betrayed, disappointed, or wronged by another human being is a universal experience. In the face of such injury, negative feelings (e.g., anger, resentment, disappointment) are common. Motivation to avoid the source of the harm, or even a desire to retaliate or seek revenge, is also typical. Indeed, revenge occurs across species (Aureli, Cozzolino, Cordischi, & Scucchi, ...
متن کاملIdentifying the location of fire refuges in wet forest ecosystems.
The increasing frequency of large, high-severity fires threatens the survival of old-growth specialist fauna in fire-prone forests. Within topographically diverse montane forests, areas that experience less severe or fewer fires compared with those prevailing in the landscape may present unique resource opportunities enabling old-growth specialist fauna to survive. Statistical landscape models ...
