Nutrient availability and herbivory control the biomass of primary producer communities to
varying degrees across ecosystems. Ecological theory, individual experiments in many …

Anthropogenic increases in nitrogen (N) and phosphorus (P) concentrations can strongly
influence the structure and function of ecosystems. Even though lotic ecosystems receive …

Biomass is one of the most fundamental measurements made in ecology. In stream ecology,
biomass is frequently used to estimate the abundance of benthic primary producers, both …

Headwater streams are key sites of nutrient and organic matter processing and retention, but
little is known about temporal variability in gross primary production (GPP) and ecosystem …

We reviewed concepts of patch dynamics and environmental heterogeneity and their
applications to the study of fluvial ecosystems, with emphasis on research published in J …

Benthic algal communities are shaped by the availability of nutrients and light and by
herbivore consumption. Many studies have examined how one of these factors affects algal …

We summarized studies on the impacts and scale effects of negative (competition, predation,
parasitism, herbivory) and positive (mutualism, commensalism, indirect facilitation) species …

Nutrient supply and herbivore presence can regulate plant biomass. The relative impact of
both of these factors, and their interactions, on periphyton biomass were examined in a …

1. We used artificial substrata in forested and open streams in South‐East Queensland,
Australia, to determine the relative importance of shading from riparian vegetation and of …

Human-induced environmental changes are causing major shifts in ecosystems around the
globe. To support environmental management, scientific research has to infer both general …
