Chondrichthyan (Holocephali, Squalomorphii and Batomorphii) remains from the Badenian of southern Hungary (Tekeres, Mecsek Mountains): the first deepwater cartilaginous fishes from the Middle Miocene of the Central Paratethys

Papers in Palaeontology, Volume 8, Issue 6, November/December 2022., 2022
Abstract Middle Miocene (Badenian) chondrichthyan fossils collected from the Tekeres Schlieren Member of the Baden Formation at Tekeres (southern Hungary, Mecsek Mts) are described here. The chondrichthyan assemblage is exceptionally diverse and well‐preserved, and consists of holocephalans, selachians and batomorphs.

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

Environmental 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)

Journal 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

Oikos, 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

Fish 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 ...
