Macro and Microstructural Characteristics of North Atlantic Deep-Sea Sponges as Bioinspired Models for Tissue Engineering Scaffolding
(Journal article; Peer reviewed, 2021)Sponges occur ubiquitously in the marine realm and in some deep-sea areas they dominate the benthic communities forming complex biogenic habitats – sponge grounds, aggregations, gardens and reefs. However, deep-sea sponges ... -
Geochemical transition zone powering microbial growth in subsurface sediments
(Journal article; Peer reviewed, 2020)No other environment hosts as many microbial cells as the marine sedimentary biosphere. While the majority of these cells are expected to be alive, they are speculated to be persisting in a state of maintenance without net ... -
Glacial microbiota are hydrologically connected and temporally variable
(Journal article; Peer reviewed, 2020)Glaciers are melting rapidly. The concurrent export of microbial assemblages alongside glacial meltwater is expected to impact the ecology of adjoining ecosystems. Currently, the source of exported assemblages is poorly ... -
Spatial covariance of herbivorous and predatory guilds of forest canopy arthropods along a latitudinal gradient
(Journal article; Peer reviewed, 2020)In arthropod community ecology, species richness studies tend to be prioritised over those investigating patterns of abundance. Consequently, the biotic and abiotic drivers of arboreal arthropod abundance are still relatively ... -
Mapping benthic ecological diversity and interactions with bottom-contact fishing on the Flemish Cap (northwest Atlantic)
(Journal article; Peer reviewed, 2020)The ecological diversity of benthic invertebrates from bottom trawl surveys was mapped for the Flemish Cap, a plateau of ~200 km radius in the northwest Atlantic. Species density (SpD), the exponential Shannon diversity ... -
Combined effects of a simulated marine heatwave and an algal toxin on a tropical marine aquaculture fish cobia (Rachycentron canadum)
(Journal article; Peer reviewed, 2020)Ongoing global warming is one of the major challenges for the development of aquaculture in the tropical regions where species are already cultured in the water temperature close to their upper physiological thresholds. ... -
A Blueprint for an Inclusive, Global Deep-Sea Ocean Decade Field Program
(Journal article; Peer reviewed, 2020)The ocean plays a crucial role in the functioning of the Earth System and in the provision of vital goods and services. The United Nations (UN) declared 2021–2030 as the UN Decade of Ocean Science for Sustainable Development. ... -
Temperate infection in a virus–host system previously known for virulent dynamics
(Journal article; Peer reviewed, 2020)The blooming cosmopolitan coccolithophore Emiliania huxleyi and its viruses (EhVs) are a model for density-dependent virulent dynamics. EhVs commonly exhibit rapid viral reproduction and drive host death in high-density ... -
Gonadal Degeneration and Hepatopancreas Alteration in Orange Mud Crab Scylla olivacea Infected With Sacculina beauforti (Crustacea; Rhizocephala; Sacculinidae)
(Journal article; Peer reviewed, 2020)Infestation of Sacculina beauforti on an aquaculture species, mud crab Scylla olivacea is alarming due to its high prevalence and the extreme morphological changes in hosts. To further understand its pathological effect ... -
From a crisis to an opportunity: Eight insights for doing science in the COVID‐19 era and beyond
(Journal article; Peer reviewed, 2020)The COVID-19 crisis has forced researchers in Ecology to change the way we work almost overnight. Nonetheless, the pandemic has provided us with several novel components for a new way of conducting science. In this perspective ... -
The First Cut Is the Deepest: Trawl Effects on a Deep-Sea Sponge Ground Are Pronounced Four Years on
(Journal article; Peer reviewed, 2020)Few studies have described the effects of physical disturbance and post-recovery of deep-sea benthic communities. Here, we explore the status of deep-sea sponge ground communities four years after being impacted by an ... -
Optimal reproductive phenology under size-dependent cannibalism
(Journal article; Peer reviewed, 2020)Intra-cohort cannibalism is an example of a size-mediated priority effect. If early life stages cannibalize slightly smaller individuals, then parents face a trade-off between breeding at the best time for larval growth ... -
Community Composition and Habitat Characterization of a Rock Sponge Aggregation (Porifera, Corallistidae) in the Cantabrian Sea
(Journal article; Peer reviewed, 2020)Deep-sea sponge-dominated communities are complex habitats considered hotspots of biodiversity and ecosystem functioning. They are classified as Vulnerable Marine Ecosystem and are listed as threatened or declining as a ... -
Possible use of lumpfish to control Caligus elongatus infestation on farmed Atlantic salmon: A mini review
(Journal article; Peer reviewed, 2020)In this mini review, we systematized current knowledge about the number of Caligus elongatus on farmed Atlantic salmon in relation to the use of lumpfish as cleaner fish. The review was prompted by reports of an unusually ... -
Ecological load and balancing selection in circumboreal barnacles
(Journal article; Peer reviewed, 2021)Acorn barnacle adults experience environmental heterogeneity at various spatial scales of their circumboreal habitat, raising the question of how adaptation to high environmental variability is maintained in the face of ... -
The Molecular Machinery of Gametogenesis in Geodia Demosponges (Porifera): Evolutionary Origins of a Conserved Toolkit across Animals
(Journal article; Peer reviewed, 2020)All animals are capable of undergoing gametogenesis. The ability of forming haploid cells from diploid cells through meiosis and recombination appeared early in eukaryotes, whereas further gamete differentiation is mostly ... -
Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change
(Journal article; Peer reviewed, 2020)Assessing the vulnerability of species to climate change serves as the basis for climate-adaptation planning and climate-smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive ... -
Rock sponges (lithistid Demospongiae) of the Northeast Atlantic seamounts, with description of ten new species
(Journal article; Peer reviewed, 2020)Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their ... -
Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf
(Journal article; Peer reviewed, 2021)The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in ... -
How trophic cascades and photic zone nutrient content interact to generate basin-scale differences in the microbial food web
(Journal article; Peer reviewed, 2020)In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that ...
