Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River. [PDF]

Ecol Evol
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 ...

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater. [PDF]

J Eukaryot Microbiol
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

Developing and Evaluating Aquatic Passive Sampling of Environmental DNA for Microbial Community Profiling. [PDF]

Mol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding has transformed biodiversity monitoring across taxa from bacteria to mammals, yet sample collection remains a major bottleneck. Passive sampling via adsorption and entrapment has emerged as a promising alternative to overcome the limitations of conventional active filtration.

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

Mol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Surface sediment diatom assemblages from four alpine lakes in the Zelengora Mountains (Bosnia and Herzegovina): A Pilot Study [PDF]

Botanica Serbica, 2022
This pilot study presents surface sediment diatom assemblages in four alpine lakes in the Zelengora Mountains. The four lakes are distributed across an alpine treeline, spanning temperate mixed forest and treeless alpine tundra zones, thus offering an
