Integrating food web diversity, structure and stability.
Given the unprecedented rate of species extinctions facing the planet, understanding the causes and consequences of species diversity in ecosystems is of paramount importance. Ecologists have investigated both the influence of environmental variables on species diversity and the influence of species diversity on ecosystem function and stability. These investigations have largely been carried ou...
متن کاملModeling Food-Web Dynamics: Complexity-Stability Implications
We discuss theoretical aspects of the broader food-web research agenda, particularly the background and various approaches used for modeling food-web dynamics in abstract systems with more than two taxa. Much of this type of modeling has oriented itself around the classic and enduring complexity-stability debate in ecology, especially those aspects which relate to the theoretical and associated...
متن کاملTrophic coherence determines food-web stability.
Why are large, complex ecosystems stable? Both theory and simulations of current models predict the onset of instability with growing size and complexity, so for decades it has been conjectured that ecosystems must have some unidentified structural property exempting them from this outcome. We show that trophic coherence--a hitherto ignored feature of food webs that current structural models fa...

Background: The study aims to study the issue of the people choices and examine the relationship between ethical marketing with consumer buying behavior. The purpose of this study was to factors related to the ethical choices of food products. Method: This research is a descriptive - survey research and in terms of its purpose is an applied research. The statistical population of this study was...
متن کاملLimits to natural selection.
We review the various factors that limit adaptation by natural selection. Recent discussion of constraints on selection and, conversely, of the factors that enhance "evolvability", have concentrated on the kinds of variation that can be produced. Here, we emphasise that adaptation depends on how the various evolutionary processes shape variation in populations. We survey the limits that populat...
