    Contributors:

    Summary: This data set contains the results of a study on taxonomic and functional differences between winter and summer zooplankton communities in lakes across a trophic gradient. Thirteen lakes ('Sites.csv') were sampled across a large trophic status gradient for zooplankton abundance, taxonomic and functional community composition, and Carbon/Nitrogen (C/N) stable isotopes in relation to environmental parameters. Zooplankton abundance and taxonomic identification were made for all stations ('Zooplankton_abundance.csv'); nutrients and C/N stable isotopes values in file 'Environmental_parameters'; lakes light conditions in summer and winter are presented in file 'Light.csv'; bulk zooplankton C/N stable isotopes are in 'Zooplankton_sia.csv' file.

The phone numbers of these individuals are confidential, and not used for any purpose other than notification during or after a natural disaster. Attributes contain a 2 letter code for general area and a 1 or 2 digit number for more specific areas. This layer is part of a collection of GIS data created for Santa Cruz County, California.
