Trophic effects of sponge feeding within Lake Baikal’s littoral zone. 1. In situ pumping rates
Demosponges dominate the littoral zone of Lake Baikal, Russia. During August 1993, we measured the in situ pumping activity of a globose sponge, Baikalospongia bacillifera, common at depths of 8-50 m. Excurrent flow speed, surface area, and oscular diameter were measured with fluorescein dye release, underwater video, and image processing for nine individual sponges; diel deployments of a heate...
متن کاملInsular lake island biogeography: using lake metrics to predict diversity in littoral zone mollusk communities
Island biogeography theory can be used to explain patterns of species richness on various types of habitat islands, including freshwater lake systems. Mollusk production in these systems also has been linked to various water-chemistry variables, such as pH, alkalinity, hardness, and specific conductance. We examined how mollusk diversity patterns were related to geographical and limnological fa...
متن کاملThe relative importance of wind and ship waves in the littoral zone of a large lake
Surface waves and their interactions with sediments and benthic organisms are the main hydrodynamic process affecting littoral ecosystems. Here, we present a long-term data set on surface-wave parameters, which was obtained from the analysis of measurements with a pressure sensor. The data set covers a time period of a year and allows for resolving waves with heights down to less than a centime...
متن کاملInteractions between Diatoms and Bacteria from phototrophic Biofilms of the littoral Zone of Lake Constance
In this report we describe different combinations of physical separation and antibiotic treatment to remove associated bacteria from freshwater diatoms. Diatoms were purified either from natural epilithic biofilms or from uni-algal cultures. We found that for most strains different purification procedures have to be combined individually. In a new approach we show that for some diatom strains t...
متن کاملAssessment of anthropogenic influences on littoral-zone aquatic communities of Lake Texoma, Oklahoma-Texas, USA
From 1999-2001, we evaluated the effects of anthropogenic activities in and around Lake Texoma, Oklahoma-Texas, USA, on the structure of littoral-zone fish and benthic invertebrate assemblages at 20 potentially impacted sites relative to paired reference sites. Spatial structuring of both assemblages was strongly related to variables associated with water clarity, water-column chlorophyll-a lev...
