Effects of River Beads on Algal Nutrient Limitation Following Severe Wildfire

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Severe wildfires often increase inputs of nitrogen (N) and phosphorus (P) to streams, which can alter nutrient limitation and primary production of benthic algae. Changes in nutrient limitation, however, vary over space and time due to physical and biological factors.

Modeling Trophic Structure and Ecosystem Functioning of the Small Fish‐Dominated Largest Lake of Bangladesh

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Kaptai Lake is a developing ecosystem with a linear food web and thereby vulnerable to external influences. The apex predator, Catfish (TL‐3.364), occupied the top trophic niches, while the overabundant (B: 3.264 t/km2) Clupeid (TL‐2.56) dominated the lower trophic level in the food web. The higher values of ecotrophic efficiency for most of the groups

Lista de microalgas epilíticas de la parte alta y media del río Gaira, Sierra Nevada de Santa Marta

open access: yesIntropica, 2015
El fitoplancton es uno de los principales productores primarios en los sistemas acuáticos; sin embargo, en los ríos, gran parte de la comunidad de microalgas se encuentran adheridas a las rocas, lo que ayuda a conformar el perifiton.

Post‐Thawing Viability of the Microalgae Scenedesmus dimorphus: The Importance of Species‐Specific Cryopreservation

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Cryopreservation of microalgae is crucial for preserving strains that are valuable for biotechnology and industry. The cryopreservation of Scenedesmus dimorphus is particularly relevant due to its emerging role in sustainable biotechnology, including its high lipid accumulation for biofuel production, adaptability to variable lighting conditions, and ...
