Experimentally testing the function of anal fins in the bluefin killifish, Lucania goodei
Journal of Fish Biology, EarlyView.Abstract Anal fins are thought to affect many functions, including swimming, sperm flow and signalling. However, there are few experimental demonstrations of these functions. We manipulated male anal fins by placing a cut in the fin. We found that cut males had lower fertilization rates than uncut males.

Ecological genetics of the cyclic parthenogens, Daphnia longispina and Daphnia pulex [PDF]
Hereditas, 2008 A population of Daphnia longispina was found to possess a relatively stable genetic structure, while a population of D. pulex appeared genetically very unstable. Unlike the population of D. magna inhabiting singlespecies pools in the same area and which maintained approximately the same level of genetic variation throughout seasons, the D.

Dietary supply with polyunsaturated fatty acids and resulting maternal effects influence host -- parasite interactions [PDF]
, 2013 Interactions between hosts and parasites can be substantially modulated by host nutrition. Polyunsaturated fatty acids (PUFAs) are essential dietary nutrients; they are indispensable as structural components of cell membranes and as precursors for ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Live observation of the oviposition process in Daphnia magna.
PLoS ONE, 2019 In favorable conditions, Daphnia magna undergoes parthenogenesis to increase progeny production in a short time. However, in unfavorable conditions, Daphnia undergoes sexual reproduction instead and produces resting eggs.

Restoration Ecology, EarlyView.Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

Effects of Multi-generational exposure of Daphnia magna to pesticides and environmental stress
, 2022 reservedPesticide contamination and increased temperature due to climate change have caused environmental issues and added stress on non-target aquatic organisms. The frequent occurrence of stress factors has forced organisms to adapt.
