The literature posits that an introduced predator population, is able to drive it's target pest population extinct, if supplemented with high quality additional food of quantity $\xi > \xi_{critical}$, \cite{SP11, SPV18, SPD17, SPM13}. We show this approach leads infinite time blow-up the population. propose alternate model in which induces competition. Analysis herein indicates there are thres...

Abstract We used 22 years of seasonally and spatially consistent monitoring data to explore marine predator–prey numerical response relationships. Specifically, we tested whether indices offspring performance (e.g. mass near the time their independence and/or growth rate) from three Antarctic krill-dependent predators, showed positive relationships with estimates krill density, determined using...

wild boar is distributed throughout iran except highly arid areas. in recent years, however, population size of wild boar has increased primarily because of reduction in population size of natural predators such as leopard. conversely, changes in land-use practices and increase in foraging of livestock in natural habitats has led to reduction of food resources and consequently, has forced the s...

Spatial aggregations arising from social behavior or habitat patchiness are common in nature and have important implications for population dynamics, community stability, and conservation. Distinguishing between these behavioral and environmental causes of pattern is of general interest to spatial ecologists and continues to be a key unresolved issue. Despite the importance of this problem, sys...

Who would be at your ideal conference? I’d love to be marooned on a desert island (with whiteboards, or at least a smooth sandy beach to scribble on) with Michael Lynch, Ralph Greenspan, Norbert Perrimon, John Mattick, Michael Wade, Thomas Whitham, Sara Via and Allen Moore. Perrimon, Mattick and Greenspan each have their own unique perspectives on how complex gene networks might work, while Whi...
