Algae and aquatic plants support river food webs through in-situ primary production. However, gross primary production (GPP) and ecosystem respiration (ER) are rarely evaluated in the conte...

Didymosphenia geminata is a stalk‐forming diatom capable of creating thick benthic mats in low‐nutrient streams. There are two hypotheses to explain the rapid worldwide increase in occurrence of nuisance D. geminata mats: (a) Cells are spread amo

The decay of mountain pine beetle (MPB) (Dendroctonus ponderosae) affected ponderosa pine (Pinus ponderosa) forests has increased organic carbon (OC) loading within the Rapid Creek watershed in the Black Hills of South Dakota, with total OC (TOC) con

Never before has the resiliency of wetland ecosystems to climatic and anthropogenic stressors been more important or more recognized by those who study these unique ecosystems. The goal of this chapter is to discuss a variety of management and restor

Nitrogen fixation can be a dominant flux of nitrogen (N) input providing up to 97 % of new N into some terrestrial and up to 82 % into some aquatic ecosystems, yet N2 fixation is rarely considered in the context of other N cycling fluxes. We compared

N2-fixing bacteria convert atmospheric N2 gas to biologically available forms, yet N limits primary production in many ecosystems. Despite an abundant source of N, other elements may limit N input via N2-fixation in benthic environments. We examined

At the International Didymo Conference (Providence, RI, USA, 2013), federal, state and local land managers asked for advice from the international scientific community. Managers need to know how to...

Didymosphenia geminata is a microscopic single-celled freshwater diatom. The invasive behavior of D. geminata is greatly altering physical and biological conditions in streams and rivers; the stalk material byproduct that D. geminata produces has the

Nitrogen fixation, the conversion of unreactive N2 gas from the atmosphere into a biologically usable form NH3, is the least studied process of the N cycle in stream ecology (Grimm and Petrone 1997). Tapping into the atmospheric N pool can only be ac
