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

open access: yesEcol 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.

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

open access: yesEcosphere, 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.
