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 autotrophic and heterotrophic. In this chapter, we (1) provide a context for the study of benthic algal biomass; (2) discuss in detail some of the more commonly used approaches to measure benthic algal biomass; and (3) describe a field exercise to examine the influence of irradiance on algal biomass, whereby these approaches can be employed and compared with each other to assess their individual performance.read more

Benthic metabolism as an indicator of stream ecosystem health
Christine S. Fellows,Joanne E. Clapcott,Joanne E. Clapcott,James Udy,James Udy,Stuart E. Bunn,Bronwyn Harch,Michael John Smith,Peter Davies +8 more
TL;DR: In this article, the authors tested direct and indirect measures of benthic metabolism as indicators of stream ecosystem health across a known agricultural land-use disturbance gradient in southeast Queensland, Australia.

Production technologies, current role, and future prospects of biofuels feedstocks: A state-of-the-art review
TL;DR: Fossil fuel continued overuse and carbon emissions issues have prompted increased research efforts on sustainable and renewable energy sources as alternative to fossil fuels as discussed by the authors, including bio-fuels.

Benthic algae stimulate leaf litter decomposition in detritus‐based headwater streams: a case of aquatic priming effect?
Michael Danger,Julien Cornut,Julien Cornut,Eric Chauvet,Eric Chauvet,Paola Chavez,Arnaud Elger,Arnaud Elger,Antoine Lecerf,Antoine Lecerf +9 more
TL;DR: The effects of a benthic diatom on aquatic hyphomycetes, bacteria, and leaf litter decomposition were investigated under two nutrient levels in a factorial microcosm experiment simulating detritus-based, headwater stream ecosystems, and diatoms and decomposers were able to coexist under both nutrient conditions.

Stream Communities Along a Catchment Land-use Gradient: Subsidy-stress Responses to Pastoral Development
TL;DR: In this region, stream health, as indicated by macroinvertebrates, primarily followed a subsidy-stress pattern with increasing pastoral development; management of these streams should focus on limiting development beyond the point where negative effects are seen.
Journal ArticleDOI
Does productivity drive diversity or vice versa? A test of the multivariate productivity-diversity hypothesis in streams.
TL;DR: The results suggest that the MPD hypothesis is a viable explanation of patterns of diversity and productivity in natural stream ecosystems, and that it has potential to merge the historical view that productivity drives diversity with a parallel view that diversity drives productivity.

Biovolume calculation for pelagic and benthic microalgae
TL;DR: A set of geometric shapes and mathematical equations for calculating biovolumes of >850 pelagic and benthic marine and freshwater microalgal genera are presented and designed to minimize the effort of microscopic measurement.
