The finding that total viral abundance is higher than total prokaryotic abundance and that a
significant fraction of the prokaryotic community is infected with phages in aquatic systems …

Dissolved organic matter (DOM) can be degraded by sunlight into a variety of photoproducts
that stimulate the growth and activity of microorganisms in aquatic environments. All …

Freshwater Ecology: Concepts and Environmental Applications is a general text covering
both basic and applied aspects of freshwater ecology and serves as an introduction to the …

The primary interpretive paradigm used to study lakes is their trophic status. Oligotrophic
lakes have low nutrient loading and low productivity, while eutrophic lakes have high …

Lakes and ponds are habitats of great human importance as they provide water for
domestic, industrial and agricultural use as well as providing food. In spite of their …

Bacterial and photochemical mineralization of dissolved organic matter were investigated in
the Amazon River system. Dissolved oxygen, dissolved organic carbon (DOC), and bacterial …

Regarding the effects of UV-B radiation on aquatic ecosystems, recent scientific and public
interest has focused on marine primary producers and on the aquatic web, which has …

Why do plants reflect in the green and have a “red edge” in the red, and should extrasolar
photosynthesis be the same? We provide (1) a brief review of how photosynthesis works,(2) …

Climate warming in North America is likely to be accompanied by changes in other
environmental stresses such as UV‐B radiation. We apply an empirical model to available …

We tested the hypothesis that light, especially UV‐B radiation, increases the availability of
dissolved organic matter (DOM) to pelagic bacteria in lake water. Filtered (0.2 µm) and …
