Calanus Copepods Are as Important as Marine Snow in Arctic Vertical Carbon Flux

Patrick R. Pata, Lucie Bourreau, Zoé Garmirian, Laure Vilgrain et autres

The vertical transport and storage of atmospheric carbon through the biological carbon pump (BCP) follows multiple pathways. The lipid pump is a recently recognized BCP process driven by the seasonal vertical migration of copepods utilizing carbon-rich lipid reserves during extended overwintering periods …

Whale foraging seascapes: Advective prey aggregation mechanisms predict North Atlantic right whale foraging grounds

Andéol Bourgouin, Nicholas R. Record, Cédric Cotté, Frédéric Maps

Abstract During foraging activity, baleen whales are generally dependent on the occurrence of dense prey patches. These are largely influenced by the interaction between ocean currents and the vertical distribution of individual prey. Identifying the spatio‐temporal dynamics of the areas where prey …

A co-construction approach to understanding the structure and function of the Ungava Bay marine ecosystem

Sonagnon Olivier Tokpanou, Samantha Farquhar, Sara Pedro, Marianne Falardeau et autres

Ecological models are essential tools for managing marine and coastal ecosystems. They improve our understanding of matter and energy flow within trophic networks and the dynamics of biological communities. In Nunavik, hunting and fishing activities, passed down through generations, have enabled Nunavummiut …

Challenges and complexities in Northern food systems: Mapping food access and decision-making in Nunavik

Samantha Farquhar, Sonagnon Olivier Tokpanou, Frédéric Maps, Tiff‐Annie Kenny et autres

The Canadian Arctic and sub-Arctic are under­going rapid ecological, social, and political transformations that profoundly affect local food systems. This study examines how households in Nunavik, Canada, navigate their complex, mixed subsistence and market-based food systems and identifies the factors shaping decision-making …

Hypoxia adaptation shapes genomic architecture and vertical niche transitions in copepods

Kevin Sugier, Romuald Laso‐Jadart, Loic Dorval, Arnaud Meng et autres

Abstract Oxygen Minimum Zone (OMZ) expansion is a major challenge to marine ecosystems and associated zooplankton. Calanoid copepods include lineages that tolerate hypoxia and exhibit functional traits such as diel vertical migrations towards, or dormancy within, hypoxic mesopelagic zones. However, the evolutionary …

First characterization of the marine ecosystem of Archer Fiord in the Lasting Ice Area of the High Arctic: a productivity paradox

Maxime Geoffroy, Audrey Limoges, Mathieu Ardyna, Lisa C. Matthes et autres

The Lasting Ice Area along the northern coastline of Ellesmere Island and Greenland will be the region where Arctic multiyear sea ice will persist the longest in a warming climate, making this area critical for ice-dependent species. In 2019, the Tuvaijuittuq Marine …

Meta-analysis of the role of zooplankton faecal pellets in ocean carbon export flux

Margaux Perhirin, Olivier Aumont, Frédéric Maps, Sakina-Dorothée Ayata

Abstract Faecal pellets of marine zooplankton play a key role in the biological carbon pump, i.e. all biologically mediated processes by which organic carbon produced by photosynthesis is stored in the ocean’s interior. Numerous factors (size and biomass of faecal pellets, composition …

Contrasting the efficiency of imaging systems for mesozooplankton indicators across Pacific and Atlantic coastal ecosystems

Anaïs Lacoursière‐Roussel, Luke S. McLean, Cyril Aubry, Frédéric Maps et autres

Mesozooplankton have a pivotal role in marine food webs, linking primary producers to higher trophic levels. Their abundance and traits serve as key indicators of ecosystem structure and function, making them essential components of long-term ocean monitoring. However, the need to monitor …

Identifying zooplankton fecal pellets from in situ images

Margaux Perhirin, Laure Vilgrain, Geneviève Perrin, Catherine Lalande et autres

Abstract Zooplankton play a crucial role in the biological carbon pump by producing sinking particles including sloppy feeding by-products, fecal pellets, molts and carcasses. However, quantifying their impact of these particles on the carbon cycle remains difficult. The contribution of fecal pellets …
