Beyond desertification: new paradigms for dryland landscapes
www.frontiersinecology.org © The Ecological Society of America C to existing paradigms – the set of practices or universally recognized achievements or perspectives that define a scientific discipline at any particular period of time – are fundamental to the progress of scientific knowledge (Kuhn 1962). While these challenges have always been part of science, the frequency and number of success...
متن کاملModeling animal landscapes.
There is an increasing need to assess the effects of climate and land-use change on habitat quality, ideally from a mechanistic basis. The symposium "Molecules to Migration: Pressures of Life" at the Fourth International Conference in Africa for Comparative Physiology and Biochemistry, Maasai Mara National Reserve, Kenya, 2008, illustrated how the principles of biophysical ecology can capture t...
متن کاملEcological roles and threats to aquatic refugia in arid landscapes: dryland river waterholes
Dryland rivers are renowned for their periods of ‘boom’ related to the episodic floods that extend over vast floodplains and fuel incredible production, and periods of ‘bust’ where the extensive channel network is restricted to the permanent refugial waterholes. Many of these 15 river systems are unregulated by dams but are under increasing pressure, especially from water abstraction and overla...
متن کاملDeep Learning for Explicitly Modeling Optimization Landscapes
In all but the most trivial optimization problems, the structure of the solutions exhibit complex interdependencies between the input parameters. Decades of research with stochastic search techniques has shown the benefit of explicitly modeling the interactions between sets of parameters and the overall quality of the solutions discovered. We demonstrate a novel method, based on learning deep n...
متن کاملModeling biodiversity dynamics in countryside landscapes.
The future of biodiversity hinges to a great extent on the conservation value of countryside, the growing fraction of Earth's surface heavily influenced by human activities. How many species, and which species, can persist in such landscapes (and analogous seascapes) are open questions. Here we explore two complementary theoretical frameworks to address these questions: species-area relationshi...
