Impact on Plankton Communities Following Abandonment of Rice Cultivation and Biotope Creation

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study clarified changes in plankton communities during the first year of fallow in long‐term cultivated paddy fields in Kyoto. These fields were in a fallow state, with no planting, cultivation, or fertilization occurring. When water was introduced at the same time of year as during active use and the fields were converted into biotopes, diversity

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

open access: yesBrazilian 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

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

open access: yesEcology 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 ...

Unraveling algae and cyanobacteria biodiversity in bromeliad phytotelmata in different vegetation formations in Bahia State, Northeastern Brazil

open access: yesActa Botânica Brasílica, 2018
Knowledge of algal and cyanobacterial diversity of phytotelmata remains poorly-known, especially for bromeliads from different vegetation formations. We investigated the microalgae communities of four species of tank bromeliads from different vegetation ...

Sustained Heatwaves Reshape the Phytoplankton–Zooplankton Community Structure in Freshwater Ecosystems: A Case Study of Shengjin Lake

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
The sustained heatwave has shaped the plankton community structure and led to high‐temperature domestication of some of the plankton. Plankton communities have the ability to resist heatwave stress. The sustained heatwave has altered the interrelationships between plankton.

Evaluation of Yellow Mealworm (Tenebrio molitor) Larvae Meal as a Carbon Source in Biofloc System for Dwarf Crayfish (Cambarellus montezumae) Culture

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
The aim of this study was to evaluate the use of Tenebrio molitor larvae meal as a carbon source in a biofloc system (BFT) to optimize the culture of C. montezumae. A trial was conducted for 24 weeks, 500 T. molitor larvae were reared with wheat bran as substrate, and hydration once a week; at the end, 9000 T.

Zooplankton in Aquaculture: A Perspective on Nutrition and Cost‐Effectiveness

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
Successful aquaculture relies on effective feeding strategies for target species, from the larval stage through to sexually mature adults, in both marine and freshwater environments. Aquatic organisms, particularly larvae, instinctively prefer live feeds like algae and zooplankton; larvae are entirely dependent on live feeds due to their undeveloped ...

New records of phytoplankton for Bangladesh. 7. <i>Phacus</i> spp.

open access: yesBangladesh Journal of Botany, 1970
Thirteen species of Phacus hitherto not reported from Bangladesh have been described and illustrated. Freshwater ponds at southern districts of Pirojpur and Barisal revealed these presence of the species.   Key words: Phytoplankton, New records, Bangladesh, Phacus, Ponds doi:10.3329/bjb.v37i1.1564 Bangladesh J.
