Lafferty et al. (2006)
General information
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.
Data type
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.
