Percent abundance of 109 diatom species collected from a Foy Lake (Montana, USA) sediment core that was sampled every ∼5–20 years, yielding a ∼7 kyr record over 800 time-steps. This dataset is associated with the following publication: Angeler, D., T. Eason, A. Garmestani, T. Spanbauer, and C. Allen. Assessing cross-scale patterns and the composition of ecological communities of alternative lake regimes. PLoS ONE. Public Library of Science, San Francisco, CA, USA, 01, (2018).
collection of sites with both biological and abiotic information - biological data covers all quality elements (macroinvertebrates, macrophytes, diatoms, other benthic algae, fish, and phytoplancton) - abiotic data comprises hydromorphological info (Gew�sserstrukturkartierung), physico-chemical info, and information about landcovering in catchment area primary aim was to aquire complete site information (complete set of environmental data and data from all organism groups), but finally the datasets turned out to be quite fregmentary More information on this dataset can be found in the Freshwater Metadatabase - BF_W_76-R-CAl (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BF_W_76-R-CAl).
