Molecular Ecology Resources, Volume 26, Issue 3, April 2026.ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...

Extracting and Enriching Ocean Biogeographic Information System (OBIS) Data with R
, 2017 Programmatic access to biodiversity data is revolutionising large-scale, reproducible biodiversity research. In the marine realm, the largest global database of species occurrence records is the Ocean Biogeographic Information System, OBIS. As of January 2017, OBIS contains 47.78 million occurrences of 117,345 species, all openly available and ...

Diversity and Distributions, Volume 32, Issue 4, April 2026.ABSTRACT Aim Essential habitats are areas that support biological and ecological functions critical for species' survival. For highly mobile and elusive marine species, aggregations in these habitats provide rare opportunities to study their ecology and inform conservation.

Diversity and Distributions, Volume 32, Issue 4, April 2026.ABSTRACT Aims Species redistributions and ecological shifts are increasingly evident in Arctic ecosystems, but few studies have examined benthic invertebrate communities using biogeographic and functional frameworks. This study examines the distribution of Arctic, Boreal, and Cosmopolitan infaunal species across a latitudinal gradient on the West ...

Ecology and Seasonal Habitat Use of Northern Bottlenose and Sowerby's Beaked Whales in the Azores
Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Beaked whales are among the least known cetaceans, yet they are regularly observed in the Azores, a region recognized as a hotspot for deep‐diving species. In this study, we analyzed opportunistic sightings collected during 1492 whale‐watching trips, including 149 beaked whale encounters, of which 89 were Sowerby's (Mesoplodon bidens) and 31 ...

Ecography, Volume 2026, Issue 3, March 2026.Published distribution data, while invaluable for understanding species' biogeography, often suffer from limitations such as dated and static representations of ranges, a bias toward latitudinal information, and lack of resolution in sampling frequency and variation in abundance throughout a species' distribution.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts
Ecography, Volume 2026, Issue 3, March 2026.Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...

Mapping Biodiversity Coast‐to‐Coast‐to‐Coast Across Canada's Three Oceans Using eDNA Metabarcoding
Environmental DNAMarine biodiversity worldwide is rapidly declining, and nowhere is this more evident than in coastal ecosystems where the impacts of climate change and anthropogenic activities concentrate.
