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...

Mathematical models are proposed to simulate migrations of prey and predators between patches. In the absence of predators, it is shown that the adaptation of prey leads to an ideal spatial distribution in the sense that the maximal capacity of each patch is achieved. With the introduction of co-adaptation of predators, it is proved that both prey and predators achieve ideal spatial distributio...

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...

this paper reviews the research on taxonomy of the trombidioidea in iran, with an updated checklist of 32 species (+5 undetermined species) belonging to five families and 22 genera. among them, 27 species (+1 undetermined species) are reported based on larvae only, three undetermined species based on adults only, and six species based on both larval and post-larval stages. also, 14 species (+3 ...

From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms. The purpose of this paper is to examine feeding constraints, morphological adaptations, and the...
