General
information
Thhis series of studies took place in streams in New Zealand, Maine and
North Carolina (USA). The food webs reported are from comparisons of
the effects of land use on stream food web structure regionally
(Townsend et al. 1998, Thompson and Townsend in press) and at a
continental scale (Thompson and Townsend 2003). Detailed methods are
presented in Jaarsma et al. (1998). These food webs have also been the
subject of reanalysis for the effects of allocation of effort (Thompson
et al. 2001), taxonomic resolution (Thompson and Townsend 2000), and
seasonal variability (Thompson and Townsend 1999).
Data type
The authors recorded the identities
of aquatic insect, algae and fish species and their trophic
interactions. Data are presented as a binary interaction matrix, in
which cells with a "1" indicate a trophic interaction between a pair of
species, and a "0" indicates no interaction.
