Thompson and Townsend
(multiple sources)
General information
This 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.
