Introduction
Currently working on the potential effects of deep-sea minnig sediment plumes on midwater communities, including the potential biological impacts and impacts on ecosystem services as well as climate resilience on the eastern Patagonian Shelf ecosystem

Article
Global climate change and a suite of other human-generated stressors are causing significant changes in the world’s oceans. Ocean stressors combine and interact, and when there are multiple stressors, the interactions are often synergistic – the combined impact is greater than the sum of their individual effects. Synergistic interactions yield non-...

Increased suspended sediment concentrations (SSC) are a major stressor across aquatic habitats. Here, the literature was synthesized to show that animal responses to increases in relative SSC (test concentration/natural background concentration) were similar in type and negative across different shallow-water (marine, estuarine, freshwater) habitat...

The establishment of thresholds is integral to environmental management. This paper introduces the use of thresholds in the context of deep-seabed mining, a nascent industry for which an exploitation regime of regulations, standards and guidelines is still in the process of being developed, and for which the roles and values of thresholds have yet...

The Clarion-Clipperton Zone (CCZ) is a 4 million km ² area in the eastern Central Pacific Ocean exhibiting large variability in environmental parameters, particularly oxygen and primary production, that is being targeted for deep-sea polymetallic nodule mining. This remote region’s pelagic biology is very poorly sampled, including for micronekton a...
Article
Full-text available
Interest in the mining of polymetallic nodules, sulfide deposits, and ferromanganese crusts in the deep sea is growing. While the impacts of deep-sea mining on benthic systems are somewhat understood, there is little information available on pelagic impacts via, for example, the discharge plume. The impacts of these suspended sediments on pelagic c...
Article
Many biodiversity patterns across the globe can be partially explained by energetics and habitat structure, including in the deep sea. Because of difficulties in logistics, studies focusing on deep-sea benthic systems often have limited sample sets that may be far apart in space. Here, we present analyses based on a well-sampled region, the northwe...
Article
Full-text available
Oceans provide critical ecosystem services, but are subject to a growing number of external pressures, including overfishing, pollution, habitat destruction, and climate change. Current models typically treat stressors on species and ecosystems independently, though in reality, stressors often interact in ways that are not well understood. Here, we...

Citation: van der Grient, J. M. A., and A. D. Rogers. 2019. Habitat structure as an alternative explanation for body-size patterns in the deep sea. Abstract. Patterns in body size are important to study as the size of an organism correlates with many biological traits of the organism. Changes in the size distribution of a community can be indicativ...
Article
While much has been learnt about the impacts of specific stressors on individual marine organisms, considerable debate exists over the nature and impact of multiple simultaneous stressors on both individual species and marine ecosystems. We describe a modelling tool (OSIRIS) for integrating the effects of multiple simultaneous stressors. The model...
Article
Full-text available
A key obstacle to conservation success is the tendency of conservation professionals to tackle each challenge individually rather than collectively and in context. We sought to prioritize barriers to conservation previously described in the conservation literature. We undertook an online survey of 154 practitioners from over 70 countries to ascerta...

Article
Full-text available
Body size (weight per individual) is an important concept in ecology. It has been studied in the deep sea where a decrease in size with increasing depth has often been found. This has been explained as an adaptation to food limitation where size reduction results in a lowered metabolic rate and a decreased energetic requirement. However, observatio...
