The distribution of coastal fish eDNA sequences in the Anthropocene

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 8, Page 1336-1352, August 2023., 2023
Abstract Aim Coastal fishes have a fundamental role in marine ecosystem functioning and contributions to people, but face increasing threats due to climate change, habitat degradation and overexploitation. The extent to which human pressures are impacting coastal fish biodiversity in comparison with geographic and environmental factors at large spatial

Late Cenozoic evolution of the latitudinal diversity gradient

open access: yesJournal of Biogeography, Volume 50, Issue 7, Page 1213-1220, July 2023., 2023
Abstract Aim The Late Cenozoic flourishing of polar marine ecosystems, just when temperatures were reaching their lowest levels, has always seemed anomalous. Such an observation is coupled with an increasing volume of molecular phylogenetic evidence to indicate that some polar taxa radiated at exceptionally high evolutionary rates.

Estimation of feeding strategies of spotted seals (Phoca largha) migrating to three regions in Hokkaido, Japan

open access: yesMarine Ecology, Volume 44, Issue 2, April 2023., 2023
Abstract To understand the current feeding habits of spotted seals, this study estimates feeding strategies based on region, season, growth stage, and sex through the results of stomach content analyses, and compares its findings with feeding habits of the past. As a result of permutational multivariate analysis of variance (PERMANOVA), region, season,

Evaluating the sampling effort for the metabarcoding‐based detection of fish environmental DNA in the open ocean

open access: yesEcology and Evolution, Volume 13, Issue 3, March 2023., 2023
We evaluated the sampling effort for the metabarcoding‐based detection of fish eDNA in the subtropical and subarctic northwestern Pacific Ocean and Arctic Chukchi Sea. The results suggested that tens of replicates or a substantial filtration volume were required to fully describe the species diversity in the open ocean, and in most cases, the turnover ...

Pathways to polar adaptation in fishes revealed by long‐read sequencing

open access: yesMolecular Ecology, Volume 32, Issue 6, Page 1381-1397, March 2023., 2023
Abstract Long‐read sequencing is driving a new reality for genome science in which highly contiguous assemblies can be produced efficiently with modest resources. Genome assemblies from long‐read sequences are particularly exciting for understanding the evolution of complex genomic regions that are often difficult to assemble.

Distinct latitudinal community patterns of Arctic marine vertebrates along the East Greenlandic coast detected by environmental DNA

open access: yesDiversity and Distributions, Volume 29, Issue 2, Page 316-334, February 2023., 2023
Abstract Aim Greenland is one of the places on Earth where the effects of climate change are most evident. The retreat of sea ice has made East Greenland more accessible for longer periods during the year. East Greenland fjords have been notoriously difficult to study due to their remoteness, dense sea ice conditions and lack of infrastructure.

Evolutionary time and species diversity in aquatic ecosystems worldwide

open access: yesBiological Reviews, Volume 97, Issue 6, Page 2090-2105, December 2022., 2022
ABSTRACT The latitudinal diversity gradient (LDG) is frequently described as the most dramatic biodiversity pattern on Earth, yet ecologists and biogeographers have failed to reach consensus on its primary cause. A key problem in explaining the LDG involves collinearity between multiple factors that are predicted to affect species richness in the same ...

Snailfishes of the Careproctus rastrinus complex (Liparidae): redescriptions of seven species in the North Pacific Ocean region, with the description of a new species from the Beaufort Sea. [PDF]

open access: yes, 2015
Herein we review and recognize as valid all previously described species of the Careproctus rastrinus complex based on morphological evidence, provide diagnoses and descriptions of all species, describe a new species from the Beaufort Sea, and address ...

Deciphering Eurasian otter (Lutra lutra L.) and seal (Phoca vitulina L.; Halichoerus grypus F.) diet: Metabarcoding tailored for fresh and saltwater fish species

open access: yesMolecular Ecology, Volume 31, Issue 19, Page 5089-5106, October 2022., 2022
Abstract Long‐lived top predators shape biodiversity structure in their ecosystems and predator–prey interactions are critical in decoding how communities function. Studies on the foraging ecology of seals and Eurasian otters in Western Europe are outdated and most studies solely performed traditional hard part analysis.
