Exposure, body size, and zooplankton overland dispersal capacity

open access: yesLimnology and Oceanography, Volume 70, Issue 1, Page 15-24, January 2025.
Abstract The dormant life stages of freshwater zooplankton are generally resistant to environmental exposure, and this facilitates their overland dispersal. However, environmental exposure and overland dispersal are less well studied for the active life stages of freshwater zooplankton.

Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered?

open access: yesEnvironmental Microbiology Reports, Volume 16, Issue 6, December 2024.
Endosymbiotic bacteria Wolbachia are recognized for their role in influencing host survival and stress resistance, particularly in cold environmental conditions across various species. However, our analysis of available data reveals a notable absence of Wolbachia in species abundant in the extreme cold conditions of Antarctica.

Mitonuclear discordance as a confounding factor in the DNA taxonomy of monogonont rotifers

open access: yes, 2017
Discordance between mitochondrial and nuclear phylogenies is being increasingly recognized in animals and may confound DNA-based taxonomy. This is especially relevant for taxa whose microscopic size often challenges any effort to distinguish between ...

Content in nine minerals and seven vitamins of rotifers (Brachionus plicatilis) fed commercial diets and two forms of Nannochloropsis oculata

open access: yesJournal of the World Aquaculture Society, Volume 55, Issue 6, December 2024.
Abstract The objective of the present study was to determine the effects of spray‐dried and fresh forms of the microalgae Nannochloropsis oculata and other commonly used commercial diets on vitamin and mineral compositions of rotifer produced under commercial conditions.

Ultrastructure and Function of the Stalk Gland Complex of Pompholyx faciemlarva (Rotifera: Monogononta)

open access: yesJournal of Morphology, Volume 285, Issue 11, November 2024.
Pompholyx mother possesses the rare ability to change the tension on the secreted thread, which alters the proximity of the egg with respect to her body. The two‐headed gland secretes a single, long, electron‐dense thread that traverses the duct and attaches to the egg surface through the cloaca. A set of retractors and protractors muscles connected to

Comparison of qPCR and metabarcoding for environmental DNA surveillance of a freshwater parasite

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
We sampled 38 freshwater sites on Fort McCoy, Wisconsin and compared qPCR to metabarcoding for eDNA detection of the ectoparasitic gill louse Salmincola edwardsii, an obligate parasite of Salvelinus fishes (chars). We found no evidence to suggest S. edwardsii occupancy or detection probabilities differed between qPCR and metabarcoding.

First ultrastructural description of an apomictic opsiblastic egg in freshwater Gastrotricha

open access: yesJournal of Morphology, Volume 285, Issue 1, January 2024.
The freshwater gastrotrich Lepidodermella squamata can produce up to three egg types: tachyblastic (fast hatching) parthenogenetic, opsiblastic (slow hatching) parthenogenetic, and plaque‐bearing (potentially sexual and diapause). Here, we provide an ultrastructural description of the opsiblastic egg, which is a single uncleaved ovum surrounded by a ...

Molecular cloning and localization of GABAA receptor-associated protein in the rotifer Brachionus plicatilis

open access: yes, 2014
γ-Aminobutyric acid receptor type A-associated protein (GABARAP) and its homologs constitute a protein family found in many eukaryotes from yeast to human, and are known to be involved in intracellular membrane trafficking of GABAA receptors and ...
