'Forbidden' links to accompany the upland streams food web

Description

A table specifying trophic links that are allowed when modelling part of the food web from upland Welsh stream containing the two macroinvetebrate predators Rhyacophila dorsalis and Dinocras cephalotes (see WelshStreams). There is one forbidden link for each predator species, preventing cannibalism from being included in the null model: this is because the method used to screen predator gut contents for prey (next generation sequencing) cannot distinguish between predator and prey of the same species. Both predators are generalists, so all other trophic links are permitted.

Usage

WelshStreams.fl

Format

A data frame with 2 rows and 17 columns, each row representing one of the two predator genera. The first column (Predator) indicates the predator genus, whilst columns 2–17 indicate which of the 16 potential prey taxa can be consumed (1) or are forbidden (0).
