Complete mitochondrial genome of the euryhaline monogonont rotifer Brachionus paranguensis (Rotifera, Brachionidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The two complete mitochondrial genomes were sequenced from the euryhaline monogonont rotifer Brachionus paranguensis. The mitochondrial genome sequences were 11,603 bp and 12,901 bp in size, and the gene order of 12 protein-coding genes (PCGs) were ...

Integrative Taxonomy of Two Peruvian Strains of Brachionus plicatilis Complex with Potential in Aquaculture

open access: yesDiversity, 2021
Two Peruvian strains of the genus Brachionus were isolated from impacted coastal wetlands. With an integrative taxonomic view, we described their taxonomic status, morphological characters, productive parameters, and phylogenetic position. In the case of

Combined effects of microplastics and temperature on the competition between Brachionus havanaensis and Brachionus calyciflorus (Rotifera)

open access: yesHydrobiologia, 2023
AbstractAquatic organisms are constantly exposed to effluents which often contain microplastics. Microplastics adversely affect aquatic organisms as a result of mechanical damage during ingestion or intoxication by chemicals adsorbed on the microplastics.

Evolutionary tradeoff and equilibrium in an aquatic predator-prey system [PDF]

open access: yes, 2004
Due to the conventional distinction between ecological (rapid) and evolutionary (slow)timescales, ecological and population models to date have typically ignored the effects of evolution.

Linking genome size variation to population phenotypic variation within the rotifer, Brachionus asplanchnoidis

open access: yesCommunications Biology, 2021
Claus-Peter Stelzer et al. take advantage of genome size variation within a natural population of the rotifer, Brachionus asplanchnoidis, to investigate the effects of genome size on phenotypic correlates, such as cell size and development time.

Variable Fitness Response of Two Rotifer Species Exposed to Microplastics Particles: The Role of Food Quantity and Quality

open access: yesToxics, 2021
Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment.

Zooplankton Assemblage Structure of the Lower Mississippi River and Floodplain in Relation to Site Hydrological Connection

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The pattern of flow or hydrological connection between a river's main channel and its floodplain can vary seasonally and spatially in frequency, duration, direction, and magnitude. Such variation is expected to promote habitat and biotic diversity.
