Cross-amplification of microsatellites from the Atherinopsidae Odontesthes perugiae and Odontesthes argentinensis to Chilean silversides of the genus Odontesthes and Basilichthys Amplificación cruzada de microsatélites de los Atherinopsidae Odontesthes perugiae y Odontesthes argentinensis en pejerreyes chilenos del género Odontesthes y Basilichthys

Gayana, 2011
We tested the amplification potential of 8 microsatellites initially described for Odontesthes perugiae and O. argentinensis in 3 species of Odontesthes and 4 species of Basilichthys.

Transcriptomic differentiation underlying marine-to-freshwater transitions in the South American silversides Odontesthes argentinensis and O. bonariensis (Atheriniformes). [PDF]

Ecol Evol, 2017
Two species of silversides have very different patterns of gene expression in the gill due to the different environments they inhabit, despite little documented genetic divergence between them. Abstract Salinity gradients are critical habitat determinants for freshwater organisms.

Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid <i>Odontesthes regia</i>. [PDF]

Ecol Evol
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...

Stable isotopes reveal minimal spatial and temporal variation in diet of the wrymouth (Cryptacanthodes maculatus)

Ecosphere, Volume 13, Issue 4, April 2022., 2022
Abstract Predation by infaunal and epibenthic predators is often an important determinant of marine soft‐bottom community structure. The role of the predatory, benthic‐dwelling fish, the wrymouth (Cryptacanthodes maculatus), in the soft‐bottom food web has received little attention.

Presence of trace elements in the silverside Odontesthes argentinensis [PDF]

, 2017
The silverside Odontesthes argentinensis is an economically significant resource for commercial fisheries in South America. We evaluated the presence of trace elements in the stomach content and fish tissues (muscle and otoliths) of O. argentinensis.

Alterations in the Gill Filaments and Secondary Lamellae of Cirrhinus mrigala Exposed to “Nuvan,” an Organophosphorus Insecticide

Journal of Histology, Volume 2014, Issue 1, 2014., 2014
The alterations in the epithelium of the gill filaments and the secondary lamellae of the gills of Cirrhinus mrigala, on exposure to “Nuvan,” have been explored in the present investigation using light and scanning electron microscopy. The fishes were exposed to two sublethal concentrations, 5 mg/L and 15 mg/L, of “Nuvan.” The changes are more rapid ...

Toxicidade aguda do Roundup Transorb ® na embriogênese do peixe-rei Odontesthes argentinensis [PDF]

, 2020
Os ecossistemas aquáticos atuam como canais ou sumidouros. Desta forma, são altamente impactados por estressores antropogênicos, acumulando contaminantes que afetam diretamente a qualidade da água. Dentre os contaminantes agrícolas, o herbicida Roundup ®
