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 [...]
Evidence to inform spatial management of a western Pacific Ocean tuna purse seine fishery
Published: 2024-01-22
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Fisheries can have profound impacts on co-occurring species exposed to incidental capture, particularly those with life history traits that make them vulnerable to elevated mortality levels. Fisheries spatial management holds substantial potential to balance socioeconomic benefits and costs to threatened bycatch species. This study analyzed observer program data for a western Pacific Ocean tuna [...]
Switching to bioplastics may exacerbate ingestion of lost and discarded fishing gear by marine invertebrates
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 [...]
Quantifying clearance rates of restored shellfish reefs using modular baskets

Subjects: Animal Experimentation and Research, Aquaculture and Fisheries Life Sciences, Biology, Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Life Sciences, Marine Biology, Oceanography and Atmospheric Sciences and Meteorology, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology, Water Resource Management, Zoology
Shellfish reefs are among the most degraded ecosystems globally, prompting substantial efforts to restore them. While biodiversity gains of restored reefs are well documented, other ecosystem services such as water filtration remain poorly quantified. We present a novel way of measuring water filtration by restored reefs using modular restoration structures called Robust Oyster Baskets (ROB 400). [...]
The world was our oyster: Records reveal the vast historical extent of European oyster reef ecosystems
Published: 2023-12-07
Subjects: Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology
Anthropogenic activities have impacted marine ecosystems at extraordinary scales. Biogenic reef ecosystems built by the European flat oyster (Ostrea edulis) typically declined prior to scientific monitoring. Collating >1,600 records published over 350 years, we created a highly resolved (10km2) map of historical oyster reef presence across its biogeographic range, including documenting abundant [...]
Historical dataset details the distribution, extent and form of lost Ostrea edulis reef ecosystems.
Published: 2023-12-07
Subjects: Aquaculture and Fisheries Life Sciences, Biodiversity, Marine Biology, Terrestrial and Aquatic Ecology
Ocean ecosystems have been subjected to anthropogenic influences for centuries, but the scale of past ecosystem changes is often unknown. For centuries, the European flat oyster (Ostrea edulis), an ecosystem engineer providing biogenic reef habitats, was a culturally and economically significant source of food and trade. These reef habitats are now functionally extinct, and almost no memory of [...]
Opinion: Missing half the picture, focus on stony corals during bleaching events has left critical knowledge gaps in our understanding of reef-scale bleaching and recovery

Octocoral Symbiodiniaceae, but not bacterial communities, are resistant to compositional changes from heat stress on a subtropical reef
Published: 2023-11-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
Microbes are essential to the holobiome of all organisms, so when organisms are impacted by environmental stressors the changes to microbial communities can inform on the health state of the host and even cause host disease. In early 2019 marine heatwaves occurred across eastern Australia, resulting in differential bleaching across Lord Howe Island reefs. Here we examined the Symbiodiniaceae and [...]
Extreme events and coupled socio-ecological systems
Published: 2023-11-20
Subjects: Agricultural and Resource Economics, Behavioral Economics, Demography, Population, and Ecology, Ecology and Evolutionary Biology, Human Ecology, Life Sciences, Marine Biology, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Rare, but potentially impactful, extreme events in socio-ecological systems (SES) can trigger significant consequences. The scarcity of theoretical frameworks for such events in SES is due to data limitations and difficulty in building coupled SES models. We explore the effect of extreme events on coupled socio-ecological systems using two stylized case studies: harvesting of old-growth forests [...]
Refining the trophic diversity, ecological network structure, and bottom-up importance of prey groups for temperate reef fishes
Published: 2023-11-07
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Marine Biology
Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles of many fish species and the importance of different prey groups for sustaining fish communities has, however, been limited by the historical classification of fishes into a few coarse trophic guilds. Using detailed diet [...]
Industrial fishing compliance with a new marine corridor near the Galapagos Islands
Published: 2023-10-30
Subjects: Agricultural and Resource Economics, Aquaculture and Fisheries Life Sciences, Life Sciences, Marine Biology
Examining fishing pressure in under-resourced marine regions still presents a challenge to understanding patterns of fishing pressure. These issues are compounded in areas with complex marine zoning regulations or those that have changed over time. Satellite-based positioning tracking of fishing vessels has helped identify ocean-wide fishing effort distribution and potential encroachments into [...]
Diversity and function of fluorescent molecules in marine animals
Published: 2023-09-05
Subjects: Biology, Life Sciences, Marine Biology
Fluorescence in marine animals has mainly been studied in Cnidaria but is found in many different phyla such as Annelida, Crustacea, Mollusca, and Chordata. While many fluorescent proteins and molecules have been identified, very little information is available about the biological function of fluorescence. In this review, we focus on describing the occurrence of fluorescence in marine animals [...]
Growth and opportunities for drone surveillance in pinniped research

Subjects: Ecology and Evolutionary Biology, Integrative Biology, Marine Biology, Other Ecology and Evolutionary Biology, Population Biology, Research Methods in Life Sciences, Zoology
Pinniped species undergo uniquely amphibious life histories that make them valuable subjects for many domains of research. Pinniped research has often progressed hand-in-hand with technological frontiers of wildlife biology, and drones represent a leap forward for methods of aerial remote sensing, heralding data collection and integration at new scales of biological importance. Drone methods and [...]

Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Microbiology
Bacteriophages, or phages, are viruses that infect and replicate within bacterial hosts, playing a significant role in regulating microbial populations and ecosystem dynamics. However, phages from extreme environments such as polar regions remain relatively understudied due to challenges like restricted ecosystem access and low biomass. Understanding the diversity, structure, and functions of [...]
