Extinction risk and structure of a food web model.
We investigate in detail the model of a trophic web proposed by Amaral and Meyer [Phys. Rev. Lett. 82, 652 (1999)]. We focus on small-size systems that are relevant for real biological food webs and for which the fluctuations play an important role. We show, using Monte Carlo simulations, that such webs can be nonviable, leading to extinction of all species in small and/or weakly coupled system...
متن کاملFood Web Architecture and Basal Resources Interact to Determine Biomass and Stoichiometric Cascades along a Benthic Food Web
Understanding the effects of predators and resources on primary producers has been a major focus of interest in ecology. Within this context, the trophic cascade concept especially concerning the pelagic zone of lakes has been the focus of the majority of these studies. However, littoral food webs could be especially interesting because base trophic levels may be strongly regulated by consumers...
متن کاملA COMPLETE Look at The Use of IRAS Emission Maps to Estimate Extinction and Dust Temperature
We have created new dust temperature and column density maps of Perseus, Ophiuchus and Serpens using 60 and 100 μm data from the IRIS recalibration of IRAS data. We describe an optimized method for finding the dust temperature, emissivity spectral index, and optical depth using optical and NIR extinction maps. The creation of these temperature and extinction maps (covering tens of square degree...
متن کاملEvolution of Complex Food Web Structure Based on Mass Extinction
We demonstrate that complex food webs may originate from mass extinctions. For this purpose, a minimal computational model for the evolution of food webs is constructed. In the model, food web structure is represented by a kind of dynamic random graph with some biological constraints, and evolves under the condition without fitness, competition among species, nor population dynamics. It is show...
متن کاملTrophic redundancy reduces vulnerability to extinction cascades
Current species extinction rates are at unprecedentedly high levels. While human activities can be the direct cause of some extinctions, it is becoming increasingly clear that species extinctions themselves can be the cause of further extinctions, since species affect each other through the network of ecological interactions among them. There is concern that the simplification of ecosystems, du...
