Respiratory Chain of Colorless Algae II. Cyanophyta [PDF]
Plant Physiology, 1966 Whole cell difference spectra of the blue-green algae, Saprospira grandis, Leucothrix mucor, and Vitreoscilla sp. have one, or at the most 2, broad alpha-bands near 560 mmu. At -190 degrees these bands split to give 4 peaks in the alpha-region for b and c-type cytochromes, but no alpha-band for a-type cytochromes is visible.

New Approaches to Assess Food Web Stability in Aquatic Ecosystems: A Case Study on Baiyangdian Lake
Ecology and Evolution, Volume 15, Issue 8, August 2025.A method for calculating the interaction strength of a phytoplankton‐based and a detritus food web. A geometric mean ratio of predator‐to‐prey biomass BCBPt$$ {\left(\frac{B_C}{B_P}\right)}_t $$ as an alternative indicator for food web stability. The changes in the stability of the BYD Lake from the 1950s to the 2010s indicate that two steady‐state ...

The role of larval density and food availability in life‐history traits of Aedes aegypti mosquitoes
Entomologia Experimentalis et Applicata, Volume 173, Issue 8, Page 892-902, August 2025.We investigated the effects of competition (food availability and larval density) on Aedes aegypti (Diptera: Culicidae) mortality and development. Food had a more pronounced effect on mortality and development time than density, but density had a higher impact on adult size and lifespan.

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Growth of off-flavours-caused phytoplankton in milkfish culture fertilized with different N:P
Jurnal Akuakultur Indonesia, 2015 Milkfish culture in ponds currently use inorganic fertilizers for growing phytoplankton. Giving of urea and SP (superphosphate) too much in the pond environment will cause eutrophication and often cause fish smell of mud (off-flavours).
