The effects of population synchrony, life history, and access constraints on benefits from fishing portfolios
Published: 2020-08-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Population Biology
Natural resources often exhibit large interannual fluctuations in productivity driven by shifting environmental conditions, and this translates to high variability in the revenue resource users can earn. However, users can dampen this variability by harvesting a portfolio of resources. In the context of fisheries, this means targeting multiple populations, though the ability to actually build [...]
Animal size and seawater temperature, but not pH, influence a repeatable startle response behaviour in a wide-ranging marine mollusc
Published: 2020-06-16
Subjects: Life Sciences, Marine Biology
Startle response behaviours are important in predator avoidance and escape for a wide array of animals. For many marine invertebrates, however, startle response behaviours are understudied, and the effects of global change stressors on these responses are unknown. We exposed two size classes of blue mussels (Mytilus edulis × trossulus) to different combinations of temperature (15 and 19 °C) and [...]
Trophic cascades and connectivity in coastal benthic marine ecosystems: a meta-analysis of experimental and observational research
Published: 2020-05-04
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Terrestrial and Aquatic Ecology
Predators often exert top-down control on lower trophic levels, such that their removal or addition can trigger trophic cascades. Despite coastal ecosystems containing well known trophic cascades, the abiotic and biotic factors governing the occurrence and strength of these cascades are still unclear. We worked to explain the variability of trophic cascades in benthic marine ecosystems by [...]
Financial and institutional support are important for large-scale kelp forest restoration
Published: 2020-04-21
Subjects: Biodiversity, Life Sciences, Marine Biology
Kelps form extensive underwater forests that underpin valuable ecosystem goods and services in temperate and polar rocky coastlines worldwide. Stressors such as ocean warming and pollution are causing regional declines of kelp forests and their associated services worldwide. Kelp forest restoration is becoming a prominent management intervention, but we have little understanding of what drives [...]
