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

Ecology 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

Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

Determinants of Cyanobacteria and Algae Diversity in Natural Freshwater Micro‐Ecosystems

Environmental Microbiology, Volume 27, Issue 8, August 2025.
The Shannon Index, turbidity and luminosity negatively affected the LCBD, species with intermediate frequency of occurrence affected the LCBD, cyanobacteria and green algae are the groups that contribute most to the SCBD, as well as species with accessory frequency.

Phytoplankton community and physical-chemical characteristics of water in the public reservoir of Cruzeta, RN, Brazil Comunidade fitoplanctônica e características físico-químicas do açude público de Cruzeta, Rio Grande do Norte, BR

Brazilian Journal of Biology, 2008
The Phytoplankton community and the abiotic factors of the Cruzeta reservoir were studied at three depths, surface, middle (2 m) and bottom, from September, 2004 to June, 2005, in order to characterize the environment and assess the possible factors that

Buffer Zone Degradation and Plankton Dynamics in Northern and Northeastern Parts of Lake Tana, Ethiopia: Implications for a Tropical Highland Lake Ecosystem

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Lake Tana, a UNESCO World Biosphere Reserve Lake. The lake contains 50% of Ethiopia's freshwater and fertile land, which favoured urbanization, agriculture and irrigation, impacting its ecosystem. Understanding the effects of buffer zone degradation on plankton and water quality was vital for sustainable resource utilization.

Synthesis of Population Trends Reveals Seascape‐Wide Reorganisation of Biodiversity From Microalgae to Birds

Global Change Biology, Volume 31, Issue 6, June 2025.
We present a systematic and quantitative analysis of population trends to capture the seascape‐wide reorganisation of biodiversity from microalgae to birds. First, we categorised population trends and found over one third of populations in the Wadden Sea to change, that is, increase or decrease.
