General Information:
Title:Symmetrical web of Carpinteria Salt Marsh
Identifier:bowdish.122.11
Abstract:
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 (Lafferty, 2006) 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.

Step by Step Procedures
Step 1:  
Description:

4 subwebs

This symmetrical web of Carpinteria Salt Marsh is comprised of 4 subwebs denoted by solid lines (clockwise: predator-prey, parasite-host, predator-parasite, parasite-parasite). Consumers in columns, prey/hosts in rows. Numerical entries represent links. Different values represent different types of links.

N = a confirmed link

N.1 represents a proposed/presumed link

0 = no link

1 = first intermediate host

1.2 = first and second intermediate host

1.25 first and second intermediate host, excysts outside 2nd intermediat host.

2 = second intermediate host

2.5 = second intermediate host external (non-trophic) cyst

3 = final host

4 = predator-prey

4.11 = 4.1

4.2 = egg predator

5 = predation on free-living cercarial stage of a trematode

6 = micropredation (mosquito)

7 = predation on parasite in a host

8 = predation on parasite in a host, transmission to predator possible

9 = parasite - parasite (mostly intraguild predation)
