The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:

Warncke, William Madara

Abstract:

The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:

Miller, Scott W.

Abstract:

I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...
