Some factors affecting primary productivity of stream riffle communities

TL;DR: Algae that regenerate in this way can adjust their growth form in accordance with varying levels of disturbance encountered in different habitats and thus incur the minimal cost consistent with survival in that area.

TL;DR: Benthic community metabolism was studied on four stream systems located in different biomes in the United States to test the hypothesis that a transition in community metabolism will occur from a predominance of heterotrophy in headwaters to a predominances of autotro Murphy in mid-sized reaches, with a return to heterotrophic further downstream.

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.

TL;DR: In this paper, a review of the algorithms used to describe these relationships are reviewed, with emphasis placed on aquatic plants in freshwater ecosystems, and the robustness of macrophyte simulation models is largely dependent on the rigour with which they are calibrated and verified against natural data representing a broad range of environmental conditions.
