Ancient and Recent Riverine Gene Flow Contributed to the Adaptive Radiation of Sailfin Silversides in Wallace's Dreampond. [PDF]

Mol Ecol
ABSTRACT While adaptive radiations significantly contribute to the world's biodiversity, much is unknown about the genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate the speciation process by generating genetic diversity on which diversifying selection can act ...

Early Life Exposure to Environmentally Relevant Levels of Endocrine Disruptors Drive Multigenerational and Transgenerational Epigenetic Changes in a Fish Model

Frontiers in Marine Science, 2020
The inland silverside, Menidia beryllina, is a euryhaline fish and a model organism in ecotoxicology. We previously showed that exposure to picomolar (ng/L) levels of endocrine disrupting chemicals (EDCs) can cause a variety of effects in M.

Gene and Blood Analysis Reveal That Transfer from Brackish Water to Freshwater Is More Stressful to the Silverside Odontesthes humensis

Frontiers in Genetics, 2018
Silversides are fish that inhabit marine coastal waters, coastal lagoons, and estuarine regions in southern South America. The freshwater (FW) silversides have the ability to tolerate salinity variations.

Flashing spots on the dorsal trunk of hardyhead silverside fish [PDF]

Royal Society Open Science, 2021
A large number of living creatures are able to use ambient light effectively in biological signalling. Atherinomorus lacunosus , a teleost fish has alignments of circular spots on its dorsal trunk. The spot consists of iridophores, whose diameters are approximately 7–10 µm.

Heterophyid trematodes (Digenea) from penguins: A new species of Ascocotyle Looss, 1899, first description of metacercaria of Ascocotyle (A.) patagoniensis Hernández-Orts, Montero, Crespo, García, Raga and Aznar, 2012, and first molecular data

International Journal for Parasitology: Parasites and Wildlife, 2019
Two species of heterophyid trematodes were found in the Magellanic penguin, Spheniscus magellanicus (Forster), from Patagonia, Argentina. Ascocotyle (Ascocotyle) patagoniensis Hernández-Orts et al.

Trophic transfer of microplastics in an estuarine food chain and the effects of a sorbed legacy pollutant

Limnology and Oceanography Letters, 2020
Microplastics are of increasing concern as they are readily ingested by aquatic organisms. This study investigated microplastic trophic transfer using larval inland silversides (Menidia beryllina) (5 d posthatch) and unicellular tintinnid (Favella spp ...

Dynamic blinking in the head of hardyhead silverside fish [PDF]

Japanese Journal of Applied Physics, 2021
Abstract Dynamic light reflection can be used to provide an efficient tool for biological sensing of micro and nano-organisms. It is therefore interesting that evidence of dynamic light reflection can also be found in the animal kingdom and that there may be alternative methods of light control actuation.

Evaluation of Reference Genes to Analyze Gene Expression in Silverside Odontesthes humensis Under Different Environmental Conditions

Frontiers in Genetics, 2018
Some mammalian reference genes, which are widely used to normalize the qRT-PCR, could not be used for this purpose due to its high expression variation. The normalization with false reference genes leads to misinterpretation of results.
