This table contains Carbon and Nitrogen stable isotope data for Silver Chub (Macrhybopsis storeriana), dreissenid mussels, and Hexagenia spp. mayflies from western Lake Erie in 2014. Samples were collected between May and September 2014 as part of both routine monitoring and a lake-wide coordinated monitoring effort. Silver Chub were collected in trawls; Hexagenia and Dreissenids were captured in benthic samples and taken from Silver Chub diets.
Recovery rates of cyanobacterial-lichen soil crusts from disturbance were examined. Plots were either undisturbed or scalped, and scalped plots were either inoculated with surrounding biological crust material or left to recover naturally. Natural recovery rates were found to be very slow. Inoculation significantly hastened recovery for the cyanobacterial/green algal component, lichen cover, lichen species richness, and moss cover. Even with inoculation, however, lichen and moss recovery was minimal. Traditional techniques of assessing recovery visually were found to underestimate time for total recovery. Other techniques, such as extraction of chlorophyll a from surface soil and measurement of sheath material accumulation,...
