In the case of Lake Washington, an entire ecosystem was ma- nipulated. At lake-wide scales, exchange processes at air-water and sediment- water interfaces become important, and responses can be followed over long periods.

Lake Washington became one of the pioneer "whole-lake" experiments. Neomysis mercedis tends to associate with the benthos during daylight hours and swims actively into the pelagic zone to hunt in the evening by actively searching and chasing prey and then striking.

The opossum shrimp Neomysis mercedis has expanded its range from the lower Columbia River upstream kilometers into Lower Granite Reservoir where it is now very abundant. We studied Neomysis ecology in the reservoir during – to better understand the physical and biological factors that shape their distribution as well as their potential role in the food by: 2.

METHODS I illustrate the use of logistic regression with the example of the mysid crustacean Neomysis mercedis feeding on zooplankton in Lake Washington, Seattle.

This predator feeds selectively on Daphnia and has been implicated in long-term changes in the zooplankton community of Lake Washington (Murtaugh, ; Edmondson and Litt, ).Cited by: Neomysis mercedis, an important invertebrate predator in some lakes and estuaries in North America, occurred at high densities (>2 mysids m−3) in Lake Washington in the early s, a period.

Introduction. Classical modeling approaches for addressing lake eutrophication are based mostly on Vollenweider's () and Dillon and Rigler () steady-state, input–output equations.

These mass-balance models predict lake total phosphorus (TP) concentrations based on TP input concentrations, phosphorus retention in the sediments, and lake hydrologic retention times, and these.

Data was collected on the population structure and fecundity of the mysidNeomysis integer and the calanoid copepodEurytemora affinis in Hickling Broad, a shallow and eutrophic brackish lake, over a two-year period / Standing biomass and production rate estimates were made using estimates of size-specific dry weights and development times obtained from laboratory measurements, field.

given the role of the beak in behaviors other than feeding and given that most previously identified beak‐feeding associations concern beak size rather than shape, it remains unclear how much of beak shape diversity is explained by feeding ecology and what.

For their helpful comments on the manuscript, I thank Katherine Barrows and Charles Collins. The ecology of the Low Salinity Zone of the San Francisco Estuary is difficult to characterize because it is the result of a complex synergy of both abiotic and biotic factors.

In addition, it continues to undergo rapid change resulting from newly introduced species, direct anthropogenic influences and climate change. Corresponding Author.
