Thompson & Townsend (multiple sources)

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.
