The Influence of Light Colour on the Behaviour of Atlantic Cod in an Experimental Setting
Published: 2024-11-15
Subjects: Behavior and Ethology, Marine Biology
Fishing technologies often exploit the visual sensitivity of target species to alter their behaviours. Atlantic cod (Gadus morhua Linnaeus, 1758) are an economically important species, commonly targeted by fisheries in the North Atlantic, yet the behaviour of adult Atlantic cod in reaction to the simultaneous presentation of various light stimuli has not been assessed in an isolated setting to [...]
The Deadly Trio: Do warming, acidification & deoxygenation destabilize the anemone-algae symbiosis?
Published: 2024-11-04
Subjects: Integrative Biology, Life Sciences, Marine Biology, Physiology, Systems and Integrative Physiology Life Sciences
Anthropogenic climate change is primarily driven by carbon dioxide release, which causes a domino effect of warming, acidification, and hypoxia in aquatic habitats. Using a fully-crossed experimental design, we investigated how exposure to this “deadly trio” of environmental stressors affects the sea anemone, Exaiptasia diaphana and its endosymbiotic dinoflagellates. To mimic conditions found on [...]

Biodiversity loss is a critical global challenge. The Kunming-Montréal Global Biodiversity Framework (GBF) sets ambitious goals to protect ecosystems, halt species loss, and enhance biodiversity. The GBF’s Monitoring Framework requires countries to track progress toward biodiversity targets using a standardized set of indicators that summarize complex trends in biodiversity. However, the [...]
Seasonal Migrants and Traditional Ecological Knowledge in a Region of Risk: The Pulse Seine Fisheries in Limfjorden, Denmark, c. 1740-1860
Published: 2024-07-31
Subjects: Aquaculture and Fisheries Life Sciences, Arts and Humanities, Biodiversity, Economic History, Environmental Studies, Marine Biology, Other Arts and Humanities, Terrestrial and Aquatic Ecology
This article presents the commercial scale and organization of the Danish pulse seine eel fishery in the Limfjord before the advent of modern offshore fisheries. Partly, for environmental concerns, the pulse seine fishery was tightly regulated, with every seine having to be checked and certified by the local district bailiffs. Here, we present the first in-depth analysis of all preserved [...]
Emergent relationships between the functional diversity of marine zooplankton and ecosystem functioning in the global ocean
Published: 2024-07-23
Subjects: Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology
Copepods are a major group of the mesozooplankton and thus a key part of marine ecosystems worldwide. Their fitness and life strategies are determined by their functional traits which allow different species to exploit various ecological niches. The range of functional traits expressed in a community define its functional diversity (FD), which can be used to investigate how communities utilize [...]
Analysis of ecologically relevant sea ice and ocean variables for the Southern Ocean using a high-resolution model to inform ecosystem studies
Published: 2024-06-28
Subjects: Marine Biology, Oceanography and Atmospheric Sciences and Meteorology
Southern Ocean organisms are uniquely adapted to the extreme environmental conditions that characterise this region, making them especially vulnerable to climate change. Alterations to the physical environment have already been linked to alterations in the structure and functioning of entire ecosystems, and ecological disruptions are expected to continue to occur. Although our understanding of [...]
Light Pollution at Sea: Implications and Potential Hazards of Human Activity for Offshore Bird and Bat Movements in the Greater North Sea

Human activity in the North Sea is intensifying, as emerging uses, such as offshore wind farms (OWFs) and liquid natural gas (LNG) terminals, are added to fishing, freight shipping and fossil fuel production as traditional forms of resource exploitation. The volume and scale of these additional installations are projected to increase substantially in the coming decades, which amplifies the need [...]
Ten golden rules for restoration to secure resilient and just seagrass social-ecological systems
Published: 2024-05-20
Subjects: Biodiversity, Ecology and Evolutionary Biology, Marine Biology, Plant Sciences
It is unequivocal that the world has lost a significant proportion of its seagrass, and although glimmers of hope exist, losses continue with many ongoing negative trajectories. First and foremost, we need to put the world on a global pathway to seagrass net gain. Conservation of what remains must be a priority, but we need to increase coverage at rates unlikely to be achieved naturally; [...]
Lumpfish, Cyclopterus lumpus, distribution in the Gulf of Maine, USA: observations from fisheries independent and dependent catch data
Published: 2024-03-29
Subjects: Aquaculture and Fisheries Life Sciences, Marine Biology, Population Biology
The Gulf of Maine (GoM) is one of the fastest-warming parts of the world’s oceans. Some species’ distributional shifts have already been documented, especially for commercially-important species. Less is known about species that are not currently exploited but may become so in the future. As a case study into these issues, we focus on lumpfish (Cyclopterus lumpus) because of the recognized and [...]
The response of trophic interaction networks to multiple stressors along a large-scale latitudinal range in the Southern Hemisphere
Published: 2024-02-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Ecological networks offer valuable insights into community structure, key species identification, and ecosystem management. Understanding how these networks respond to global change stressors is of increasing interest, especially along geographical gradients. This review summarizes potential stressor responses in marine food webs from the Southwest Atlantic to the Antarctic (45 - 78°S), [...]
Cryptic species and hybridisation in corals: challenges and opportunities for conservation and restoration
Published: 2024-02-14
Subjects: Genomics, Marine Biology, Other Ecology and Evolutionary Biology
The conservation and management of coral reef ecosystems will benefit from accurate assessments of reef-building coral species diversity. However, the true diversity of corals may be obfuscated by cryptic yet genetically distinct groups, which are likely more pervasive than currently recognised. Here, we investigate the prevalence of cryptic coral groups and assess evidence for their permeability [...]
Hybridization potential of brown trout, with particular reference to invaded environments
Published: 2024-01-25
Subjects: Aquaculture and Fisheries Life Sciences, Biodiversity, Ecology and Evolutionary Biology, Evolution, Life Sciences, Marine Biology, Population Biology
Hybridization is a complex process beginning with the mating of two species. However, hybrid offspring frequency does not predict hetero-specific mating frequency, as post-mating, both pre-zygotic and post-zygotic barriers influence their occurrence. Post-zygotic outbreeding depression usually results in poor embryo-juvenile survival or the production of sterile hybrid offspring. Females have [...]
Predicting organismal response to marine heatwaves using mechanistic thermal landscape models
Published: 2024-01-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
Marine heatwaves (MHWs) can cause thermal stress in marine ectotherms, experienced as a pulse against the press of anthropogenic warming. When thermal stress exceeds organismal capacity to maintain homeostasis, organism survival becomes time-limited and can result in mass mortality events. Current methods of detecting and categorizing MHWs rely on statistical analysis of historic climatology, and [...]

Published: 2024-01-09
Subjects: Animal Experimentation and Research, Biology, Environmental Health Life Sciences, Life Sciences, Marine Biology, Natural Resources and Conservation, Sustainability
Bioplastics are argued to be more environmentally sustainable than conventional plastics. Yet, little is known about how bioplastics degrade in marine environments or their likelihood of being ingested by animals. We measured changes in the weight of biodegradable, semi-biodegradable, and non-biodegradable fishing gears (soft plastic lures, SPLs) in or out of seawater over 14 days. We then [...]
