Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Animal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Identifying hybridizing taxa within the Daphnia longispina species complex: a comparison of genetic methods and phenotypic approaches

, 2010
Daphnia galeata Sars, D. longispina O. F. Muller and D. cucullata Sars (Crustacea: Cladocera) are closely related species which often produce interspecific hybrids in natural populations.

Evolution and expression of the highly variable cell adhesion molecule Dscam in the crustacean Daphnia and other arthropods [PDF]

, 2012
The Down syndrome cell adhesion molecule (Dscam) family, is within the cell adhesion molecules, a family whose members are characterized by being composed of immunoglobulin (Ig) and fibronectin domains and which are known to play an essential role in ...

Ciliated Epibionts Modify the Cardiac Stress Reaction to Perceived Predation in Daphnia

Microorganisms
When animals perceive an acute stressor like a predator, they typically undergo a suite of physiological changes that function to improve survival during the encounter, such as elevation in cardiac output, to supply more energy to muscles.

Episodic zooplanktivory by largemouth bass (Micropterus salmoides) on Daphnia: a 25-year natural history record from a small northern temperate lake

Journal of Freshwater Ecology, 2020
We observed episodic zooplanktivory by largemouth bass (Micropterus salmoides; LMB) ≥ 150 mm total length (TL) on the cladoceran Daphnia spp. over two decades in a small oligotrophic lake. While zooplanktivory is beneficial for young-of-year and juvenile

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

Animal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Cytological and molecular description of Hamiltosporidium tvaerminnensis gen. et sp. nov., a microsporidian parasite of Daphnia magna, and establishment of Hamiltosporidium magnivora comb. nov. [PDF]

, 2010
We describe the new microsporidium Hamiltosporidium tvaerminnensis gen. et sp. nov. with an emphasis on its ultrastructural characteristics and phylogenetic position as inferred from the sequence data of SSU rDNA, alpha-and beta-tubulin.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Evaluation of Possible Causes of Non-Predatory Mortality of Crustacean Zooplankton in a Small Siberian Reservoir [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2008
Non-predatory specific mortality (NPSM) of dominant zooplankton species, Daphnia (longispina group) and Cyclops vicinus, was estimated during 1997-2000 sampling seasons on the basis of a new direct method: live/dead sorting and sediment trap measurements.
