Contrasting functional responses of benthic and hyporheic stream biofilms to light availability and macronutrient stoichiometry

Limnology and Oceanography, EarlyView.
Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

Inundation of different river bank heights influences organic matter concentrations and zooplankton abundance

Limnology and Oceanography, EarlyView.
Abstract Regulation and water extraction change flow regimes in lowland rivers, affecting ecosystem functions and wetting patterns of riverbanks. River connectivity to lateral environments is crucial for organic matter cycling and the life cycles of diapausing microinvertebrates. While extreme hydraulic periods (floods and cease‐flow) are well‐studied,

Chlorophyll-chlorophyll and chlorophyll-water interactions in the solid state

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
Abstract Absorption spectra in the visible and infrared have been recorded for films of dry chlorophyll a , chlorophyll b , bacteriochlorophyll, pyrochlorophyll a , and pheophytin a . The effects of water on the spectra have also been studied.
