Lafferty et al.
The study was conducted in
Carpinteria Salt Marsh Reserve, Carpinteria, Santa Barbara County,
California. The purpose of the study was to investigate the effect of
parasites on food-web topology. The results are reported in detail in
Lafferty et al (in press) with other publications forthcoming which
examine connectance, chain length, vulnerability, etc. This publication
also details how taxa and links were selected for inclusion and
provides additional information on the species lists.
The matrix breaks down into 4
subwebs: predator-prey, parasite-host, predator-parasite and
parasite-parasite. Links are binary (presence or absence of
interspecific interactions), but coded by type of trophic interaction
and certainty. The links are from a combination of published reports,
direct observations, and logical, but presumed interactions. A key is
included as a text box in the matrix. The web is being updated
regularly as new information is obtained.
