First North Pacific records of the pointy nosed blue chimaera, Hydrolagus cf. trolli (Chondrichthyes: Chimaeriformes: Chimaeridae)

open access: yesMarine Biodiversity Records, 2016
The occurrence of Hydrolagus cf. trolli is reported for the first time from the central and eastern North Pacific Ocean. This is a geographic range extension for this species, as it was previously only known to occur in the southern Pacific Ocean off of ...

Feeding ecology and trophic level of Chimaera monstrosa Linnaeus, 1758 (Holocephali: Chimaeridae) in the Eastern Mediterranean

open access: yes, 2016
The feeding ecology of Chimaera monstrosa at a depth of 550 m was studied off Sigacik Bay, Eastern Mediterranean, in 2008. Forty males and 57 females with a length between 7.80 and 45.5 cm were caught. 33 stomachs contained food items.

Expanding the temporal and spatial scales of environmental DNA research with autonomous sampling

open access: yesEnvironmental DNA, Volume 4, Issue 4, Page 972-984, July 2022., 2022
Long‐range autonomous underwater vehicles equipped with autonomous environmental sample processors provide a new means for scaling up marine eDNA research. This comparative study provides evidence that autonomous eDNA sampling compares favorably to commonly used shipboard methods.

First recorded case of leucism in the velvet belly lantern shark Etmopterus spinax (Squaliformes: Etmopteridae)

open access: yesJournal of Applied Ichthyology, Volume 38, Issue 4, Page 455-461, July 2022., 2022
Abstract The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North‐eastern Atlantic) in 2021 by bottom trawling. The lack of dermal melanophores combined with a normal retinal pigmentation, lead us to considerate the ...

Nutritional grouping of marine forage species reveals contrasted exposure of high trophic levels to essential micro‐nutrients

open access: yesOikos, Volume 2022, Issue 7, July 2022., 2022
By transferring energy and nutrients from plankton to top predators, forage species play a major ecological role in marine food webs. While large differences in energy densities have been demonstrated among these species, other determinants of their quality remain poorly explored.

Ecological vulnerability of the chondrichthyan fauna of southern Australia to the stressors of climate change, fishing and other anthropogenic hazards

open access: yesFish and Fisheries, Volume 22, Issue 5, Page 1105-1135, September 2021., 2021
Abstract We develop a potentially widely applicable framework for analysing the vulnerability, resilience risk and exposure of chondrichthyan species to all types of anthropogenic stressors in the marine environment. The approach combines the three components of widely applied vulnerability analysis (exposure, sensitivity and adaptability) (ESA) with ...
