Methods

Note BioTIME managers: these data are a subset of the Density data for Lake Ontario benthic invertebrate assemblages from 1964 to 2018. The datsets contains records sampled with equivalent methods in years 1997,1998 & 1999.1997 samples were collected in early September (1997) at 51 and 68 stations, respectively (Lozano et al. 2001, Fig. 6), at depths from 12 to 213 m using Ponar (0.048 m2) and a 500 ?m sieve (U.S. Standard No. 35). Station locations in 1997 were based on a randomized design using a systematic grid (Stevens 1997). At each station, three replicate samples were collected but then were pooled into a single sample. The 1998 and 1999 data (Watkins et al. 2007) were collected following the stratified random design used in 1997 and used the same size Ponar and sieve mesh (Lozano et al. 2001). 114 samples were collected in September 1998 (Fig. 7A) aboard the U.S. EPA vessel R/V Lake Guardian, and 67 samples were collected in August 1999 (Fig. 7B) aboard the R/V Lake Explorer. Abundance is the the average density (individuals/m2) of individuals of each taxon found at each station (as average of all replicates collected at this station).
