Limits to trophic levels and omnivory in complex food webs: theory and data
RJ Williams, ND Martinez - The American Naturalist, 2004 - journals.uchicago.edu
While trophic levels have found broad application throughout ecology, they are also in much
contention on analytical and empirical grounds. Here, we use a new generation of data and …

Defining invasiveness and invasibility in ecological networks
The success of a biological invasion is context dependent, and yet two key concepts—the
invasiveness of species and the invasibility of recipient ecosystems—are often defined and …

Advances in molecular ecology: tracking trophic links through predator–prey food‐webs
SK Sheppard, JD Harwood - Functional ecology, 2005 - Wiley Online Library
Summary 1 It is not always possible to track trophic interactions between predators and prey
by direct observation. This is especially true when observing small or elusive animals with …

Applications, considerations, and sources of uncertainty when using stable isotope analysis in ecotoxicology
Stable isotope analysis (SIA) has become a powerful tool for ecotoxicologists to study
dietary exposure and biomagnification of contaminants in wild animal populations. The use …

Foraging time optimization and interactions in food webs
PA Abrams - The American Naturalist, 1984 - journals.uchicago.edu
The consequences of foraging time optimization by one species in a food web on
interactions in the food web are investigated using several simple mathematical models. The …

Effect of complexity on marine ecosystem models
Ecosystem rather than species management has become an explicit part of policies that
feature in international treaties and national legislation. Many of the tools that will be needed …

Statistical interpretation of species composition
The relative abundance of different species characterizes the structure of a biological
community. We analyze an experiment addressing the relationship between omnivorous …

[HTML][HTML] The stability and collapse of marine ecosystems during the Permian-Triassic mass extinction
The history of Earth's biodiversity is punctuated episodically by mass extinctions. These are
characterized by major declines of taxon richness, but the accompanying ecological …

Does food web theory work for marine ecosystems?
J Link - Marine ecology progress series, 2002 - int-res.com
More recent and extensive food web studies have questioned some of the prevailing
paradigms of food web theory. Yet with few exceptions, most food webs and associated …
