A Latitudinal Cline in the Taxonomic Structure of Eelgrass Epifaunal Communities is Associated With Plant Genetic Diversity Open
Aim Biogenic structural complexity increases mobile animal richness and abundance at local, regional and global scales, yet animal taxa vary in their response to complexity. When these taxa also vary functionally, habitat structures favour…

Worldwide variation in shape and size of orca (<i>Orcinus orca</i>) saddle patches Open
The global distribution of Orcinus orca (orcas/killer whales) encompasses populations which differ from each other. Saddle patch shapes and sizes were compared for nearly 4,000 individuals, in 48 geographically or ecologically divided grou…

Climate drives the geography of marine consumption by changing predator communities Open
The global distribution of primary production and consumption by humans (fisheries) is well-documented, but we have no map linking the central ecological process of consumption within food webs to temperature and other ecological drivers. …

Interacting effects of local and global stressors on mussel beds and ecosystem functioning Open
Biogenic habitats, such as mussel beds, provide various functions in their associated ecosystems. However, these habitat-forming species are exposed to cumulative impacts as the number and diversity of anthropogenic stressors increase, par…

Freshwater input significantly reduces specific and functional diversity of small subarctic estuaries Open
Estuaries face mounting anthropic pressures. Climate change is projected to increase heavy precipitations, while agricultural and logging activities reduce land permeability, leading to more frequent flooding events that lower estuarine sa…

Correction factors for large-scale greenhouse gas assessment from pulp and paper mill sludge landfill sites Open
Assessments of greenhouse gas (GHG) emissions in managed areas are facing various challenges. A non-flow-through, non-steady-state (NFT-NSS) chamber coupled to a frame permanently inserted into the landfilled substrates is a standard metho…

Images confirm records of Fijian orca (Orcinus orca Linnaeus, 1758), including a group with indistinct saddle patches Open
We collated (n=36) records of orca (Orcinus orca Linnaeus, 1758, also known as the killer whale (Cetacea Delphinidae) in the waters of the Republic of Fiji, South Pacific Ocean. Using standardised criteria, we classified these records into…

Ocean currents drive the worldwide colonization of the most widespread marine plant, eelgrass (<i>Zostera marina</i>) Open
Currents are unique drivers of oceanic phylogeography and so determine the distribution of marine coastal species, along with past glaciations and sea level changes. Here, we reconstruct the worldwide colonization history of eelgrass ( Zos…

A Pleistocene legacy structures variation in modern seagrass ecosystems Open
Distribution of Earth’s biomes is structured by the match between climate and plant traits, which in turn shape associated communities and ecosystem processes and services. However, that climate–trait match can be disrupted by historical e…

Remote Sensing of Coastal Vegetation Phenology in a Cold Temperate Intertidal System: Implications for Classification of Coastal Habitats Open
Intertidal vegetation provides important ecological functions, such as food and shelter for wildlife and ecological services with increased coastline protection from erosion. In cold temperate and subarctic environments, the short growing …

The biogeography of community assembly: latitude and predation drive variation in community trait distribution in a guild of epifaunal crustaceans Open
While considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Studying how the distributions of traits in communiti…

Photoacclimation and Light Thresholds for Cold Temperate Seagrasses Open
Water quality deterioration is expected to worsen the light conditions in shallow coastal waters with increasing human activities. Temperate seagrasses are known to tolerate a highly fluctuating light environment. However, depending on the…

Hidden Stores of Organic Matter in Northern Lake Ice: Selective Retention of Terrestrial Particles, Phytoplankton and Labile Carbon Open
Around 50% of the world's lakes freeze seasonally, but the duration of ice‐cover is shortening each year and this is likely to have broad limnological consequences. We sampled freshwater ice and the underlying water in 19 boreal and polar …

Joint effects of patch edges and habitat degradation on faunal predation risk in a widespread marine foundation species Open
Human activities degrade and fragment coastal marine habitats, reducing their structural complexity and making habitat edges a prevalent seascape feature. Though habitat edges frequently are implicated in reduced faunal survival and biodiv…

Eelgrass biomass (dry weight) measured through a multi-factorial in situ experiment of 10 weeks in a eelgrass bed in St. Lawrence Estuary (Baie-Saint-Ludger, Canada) Open
We evaluated single and interactive effects of density reduction of Zostera marina L., a habitat-forming species, shading, and sediment nutrient enrichment on the response of intertidal epibenthic macro-species abundances. Abundances were …

Latitudinal variation in plant defence against herbivory in a marine foundation species does not follow a linear pattern: The importance of resource availability Open
Aim Studies on latitudinal patterns in plant defence have traditionally overlooked the potential effect that resource availability may have in shaping plant defence. Likewise, latitudinal patterns of tolerance traits have rarely been studi…

Multiple stressors and disturbance effects on eelgrass and epifaunal macroinvertebrate assemblage structure Open
Multiple forms of environmental change and anthropogenic pressure co-occur in coastal marine ecosystems. These external forces affect ecosystem structure, functioning, and, eventually, services to humans. Studies that include more than 2 s…
