Capturing drifting species and molecules—Lessons learned from integrated approaches to assess marine metazoan diversity in highly dynamic waters

open access: yesEnvironmental DNA, Volume 5, Issue 6, Page 1541-1556, November 2023., 2023
By using an integrated morphological and genetic approach, we validated eDNA and zooplankton metabarcoding as a holistic approach to reliably identify marine metazoan fauna in highly dynamic waters of the North Sea. COI metabarcoding outperformed 18S V4 metabarcoding in terms of the number of detected species.

Target‐capture probes for phylogenomics of the Caenogastropoda

open access: yesMolecular Ecology Resources, Volume 23, Issue 6, Page 1372-1388, August 2023., 2023
Abstract Target‐capture approaches have facilitated a rapid growth in the field of phylogenomics but few probe sets exist for molluscs, an exceptionally rich phylum with unparalleled ecological and morphological diversity. We designed and tested the first universal probe set using Phyluce to capture ultraconserved elements (UCEs) and exon loci from the

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.

Complete mitochondrial genome of Volutharpa perryi (Neogastropoda: Buccinidae) [PDF]

open access: yesMitochondrial DNA Part B, 2016
In this study, the complete mitochondrial genome of Volutharpa perryi has been determined for the first time. The mitogenome is of 15 255 bp in length, including 13 protein-coding genes, two ribosomal RNA genes and 22 transfer RNA genes. The overall base composition is 29.6%, 38.6%, 15.6% and 16.2% for A, T, C and G, respectively.

Feeding effects of the keystone deposit feeder Ilyanassa obsoleta (Neogastropoda, Gastropoda) on sedimentary diatoms

open access: yesJournal of Phycology, Volume 59, Issue 3, Page 590-602, June 2023., 2023
Abstract Microphytobenthos (MPB), typically comprised mainly of diatoms, is a key contributor to nearshore energy flow and nutrient cycles. Deposit‐feeding invertebrates are known to alter the structure and activity of MPB. The eastern mud snail Ilyanassa obsoleta can reach extremely high densities in estuaries of the northwestern Atlantic, and their ...

Annotated checklist and genetic data for parasitic helminths infecting New Zealand marine invertebrates

open access: yesInvertebrate Biology, Volume 141, Issue 3, September 2022., 2022
Abstract Parasitic helminths with complex life cycles require multiple hosts in a particular order to complete their life cycles. Although almost all helminths infect invertebrates at some point in their life cycle, we know very little about which species of invertebrates harbor parasites compared with what is known for vertebrates. In New Zealand, <1%

The Early Origin of the Antarctic Marine Fauna and Its Evolutionary Implications. [PDF]

open access: yesPLoS ONE, 2014
The extensive Late Cretaceous - Early Paleogene sedimentary succession of Seymour Island, N.E. Antarctic Peninsula offers an unparalleled opportunity to examine the evolutionary origins of a modern polar marine fauna.

Origin of the tropical–polar biodiversity contrast

open access: yesGlobal Ecology and Biogeography, Volume 31, Issue 6, Page 1207-1227, June 2022., 2022
Abstract Aim The aim was to investigate the evolutionary origins of the striking biodiversity contrast between high‐ and low‐latitude regions in the present day. Is this a relatively recent phenomenon, causally linked in some way to the greenhouse–icehouse transition and onset of global cooling c.

Neogastropod phylogenetic relationships based on entire mitochondrial genomes

open access: yesBMC Evolutionary Biology, 2009
Background The Neogastropoda is a highly diversified group of predatory marine snails (Gastropoda: Caenogastropoda). Traditionally, its monophyly has been widely accepted based on several morphological synapomorphies mostly related with the digestive ...
