Transcriptomic insights into polyketides and toxin biosynthesis genes in freshwater dinoflagellates

Scientific Reports
Freshwater dinoflagellates are typically considered non-toxic, and their polyketides and toxin biosynthesis genes are largely unexplored. Here, we generated and analyzed the transcriptome of freshwater dinoflagellate Palatinus apiculatus and compared it ...

Panbiogeographical analysis of Costa Rican freshwater fishes

Revista de Biología Tropical, 2008
Track analysis and Parsimony analysis of endemicity (PAE) were performed to analyze the distribution pattern of Costa Rican freshwater fishes. A basic matrix (presence/absence) was prepared using the distribution of 77 freshwater fish.

Single and multiple stressors alter phytoplankton biomass and diversity with contrasting responses of Bacillariophyta and other phytoplankton

Water Biology and Security
Shallow lakes provide vital ecological services yet face escalating threats from climate warming, eutrophication, and imidacloprid pollution. Understanding how these stressors individually and interactively impact phytoplankton—the cornerstone of aquatic

Addressing Water Scarcity using Repurposed Oil Carriers

Natural Built Social Environment Health
Freshwater scarcity causes social, economic, political, and environmental unrest.  With unequal freshwater distribution globally, trading of freshwater can be a possible solution. But water trade, unlike oil trade, is not a recognized market.

RESEARCH METHODOLOGY ON NATURAL NUTRITION OF FRESH-WATER FISH [PDF]

Croatian Journal of Fisheries, 2001
This paper offers the entire review on the research methodology in natural nutrition of fresh-water fish. The data on fresh-water fish nutrition, particularly on fish of lower economic value, is inadequate.

Fish eDNA Composition Along a Gradient of Freshwater eDNA in an Estuarine Bay

Environmental DNA
Metabarcoding of environmental DNA (eDNA) is becoming practically applied to fish monitoring and conservation surveys in estuaries. However, estuarine bays may be an unsuitable zone to use eDNA metabarcoding because they are affected by eDNA originating ...

Diatom metabarcoding vs. morphology in monitoring freshwater and saline lakes in Serbia

Frontiers in Ecology and Evolution
IntroductionDiatoms are among the most widely used indicators for assessing ecological conditions in aquatic habitats, yet traditional microscopy remains time-consuming and taxonomically demanding.
