Freshwater bacteria are at the hub of biogeochemical cycles and control water quality in
lakes. Despite this, little is known about the identity and ecology of functionally significant …

In this article we review the biological effects of Al, primarily with respect to the chemical
factors controlling Al bioavailability and toxicity, and how its biological effects are best …

The provisioning of sustaining goods and services that we obtain from natural ecosystems is
a strong economic justification for the conservation of biological diversity. Understanding the …

An understanding of the relationship between species richness and productivity is crucial to
understanding biodiversity in lakes. We investigated the relationship between the primary …

In order to assess how diversity changes over time at sites undergoing environmental
change, we examined three data sets on long-term trends in taxonomic richness and …

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 …

Assemblages of coexisting species are formed by immigration from a regional pool of
colonists and local interactions among species and with the physical environment. Theory …

Aquatic ecosystems are connected over large spatial scales, have varied drivers, strong and
often conflicting societal interests and interacting management processes. Many of the …

As lakeshores are developed, property owners often thin the riparian forest and remove
older logs or fallen limbs from the adjacent littoral zone. This practice alters fish habitat and …

As part of the Episodic Response Project (ERP), we studied the effects of episodic
acidification on fish in 13 small streams in the northeastern United States: four streams in the …
