Evolution of realized Eltonian niches across Rajidae species [PDF]

open access: yesEcosphere, 2021
The notion that closely related species resemble each other in ecological niche space (i.e., phylogenetic dependence) has been a long‐standing, contentious paradigm in evolutionary biology, the incidence of which is important for predicting the ecosystem‐

DNA barcoding unveils skate (Chondrichthyes: Rajidae) species diversity in ‘ray’ products sold across Ireland and the UK [PDF]

open access: yesPeerJ, 2013
Skates are widely consumed across the globe, but many large species are subject to considerable concern regarding their conservation and management. Within Europe such issues have recently driven policy changes so that, for the first time, reports of ...

The description of two new species of Chloromyxum from skates in the Argentine Sea reveals that a limited geographic host distribution causes phylogenetic lineage separation of myxozoans in Chondrichthyes [PDF]

open access: yesParasite, 2018
During a survey on the myxosporean fauna of Rajiformes from the Atlantic coast of Argentina, in waters off Buenos Aires Province (34°–42°S; 53°–62°W), the gall bladders of 217 specimens belonging to seven species of skates, representatives of two ...

From coexistence to competitive exclusion: can overfishing change the outcome of competition in skates (Chondrichthyes, Rajidae)?

open access: greenLatin American Journal of Aquatic Research, 2012
Competition for food could be a major force driving changes in the community structure of skates (Rajidae) subjected to fishing exploitation. Under this hypothesis, small skates are released from competition with larger skates after fishing has depleted ...

Application of spatially robust stereo-BRUV sampling for quantifying fish assemblages in UK marine protected areas. [PDF]

open access: yesEcol Appl
Abstract Marine protected areas (MPAs) often lack adequate data on the status of marine assemblages to support evidence‐based management. Stereo baited remote underwater video (BRUV) systems offer a powerful, low‐cost tool for collecting ecological data, yet they remain underutilized in the North East Atlantic, especially compared to more invasive ...
