Genomic signatures of recombination in a natural population of the bdelloid rotifer Adineta vaga

Nature Communications, 2018
Sexual reproduction is almost ubiquitous among extant eukaryotes. As most asexual lineages are short-lived, abandoning sex is commonly regarded as an evolutionary dead end. Still, putative anciently asexual lineages challenge this view.

The significance of phosphorus in algae growth and the subsequent ecological response of consumers

Journal of Freshwater Ecology, 2022
Human activities have substantially disrupted phosphorus (P) cycles in the ecosystem, affecting producers and consumers along the food chain. To assess the ecological effects of imbalanced P on producers as well as consumer reactions to changes in food ...

Change in prey genotype frequency rescues predator from extinction

Royal Society Open Science, 2022
Indirect evolutionary rescue (IER) is a mechanism where a non-evolving species is saved from extinction in an otherwise lethal environment by evolution in an interacting species.

Rotifer Brachionus rotundiformis enriched with taurine for survival and growth of larval milkfish Chanos chanos

Jurnal Akuakultur Indonesia
This research evaluated the effect of taurine-enriched rotifers on the survival and growth of milkfish larvae. Twenty-five fertilized milkfish eggs were placed in a 250 L cylindrical fiber tank.

Comparison of taxon-based and trophi-based response patterns of rotifer community to water quality: applicability of the rotifer functional group as an indicator of water quality

Animal Cells and Systems, 2017
Rotifer community is often used as a taxon-based bioindicator for water quality. However, studies of the planktonic community from the viewpoint of functional groups in freshwater ecosystems have been limited, particularly for rotifers.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Long‐term monitoring reveals biomass loss and concurrent dominance changes in coastal zooplankton community

Ecography, EarlyView.
Anthropogenically induced changes in environmental conditions have been affecting species communities globally, leading to shifts in ecosystem functioning. Physical drivers like temperature, salinity and acidification are especially important in coastal ecosystems, and high‐resolution time‐series are essential to identify how these variables affect ...
