Abstract Baited remote underwater stereo‐video systems (stereo‐BRUVs) are a popular tool to sample demersal fish assemblages and gather data on their relative abundance body size structure in robust, cost‐effective non‐invasive manner. Given the rapid uptake of method, subtle differences have emerged way stereo‐BRUVs deployed how resulting imagery is annotated. These disparities limit interoperability datasets obtained across studies, preventing broadscale insights into dynamics ecological...
A global survey of coral reefs reveals that overfishing is driving resident shark species toward extinction, causing diversity deficits in reef elasmobranch (shark and ray) assemblages. Our species-level analysis revealed declines 60 to 73% for five common individual were not detected at 34 47% surveyed reefs. As become more shark-depleted, rays begin dominate Shark-dominated assemblages persist wealthy nations with strong governance highly protected areas, whereas poverty, weak governance,...
To support sustainable growth of ocean-based economies, many countries are engaging in marine spatial planning (MSP) processes, which require robust decision-support tools. Systematic conservation (SCP) is commonly used decision-making to guide spatially efficient protected area expansion. Here we contend that SCP can also be streamline MSP negotiations by developing a coherent, integrated portfolio sites for multiple sectors depend on biodiversity being maintained good state, as...

Marine Protected Areas (MPAs) offer a unique opportunity to test the assumption that fishing pressure affects some trophic groups more than others. Removal of larger predators through is often suggested have positive flow-on effects for lower groups, in which case protection from should result suppression as predator populations recover. We tested this by assessing differences structure reef fish communities associated with 79 MPAs and open-access sites worldwide, using standardised...
Maintaining healthy, productive ecosystems in the face of pervasive and accelerating human impacts including climate change requires globally coordinated sustained observations marine biodiversity. Global coordination is predicated on an understanding scope capacity existing monitoring programs, extent to which they use standardized, interoperable practices for data management. also identification gaps spatial ecosystem coverage, how these correspond management priorities information needs....
Abstract Most platforms for collecting images to characterise marine benthic habitats involve a downward or forward‐facing field of view that is relatively constrained (~70°), covering small area benthos (downward ~1 m 2 , forward ~25 ). Here we propose the use four‐camera platform having wide combined (~280°), much greater (up 100 We also present stereo‐camera configuration has added benefit being able accurately measure sample and dimensions biota.

Although there is some variation in how different studies have approached video sampling, [22][23][24][25][26][27] the techniques can broadly be grouped as (1) unbaited remote underwater systems (RUVs), (2) baited RUVs (BRUVs), (3) diveroperated (DOVs), (4) stereo-RUVs, (5) stereo-BRUVs and (6) stereo-DOVs.In addition, remotely
South Africa has taken an iterative approach to marine ecosystem mapping over 18 years that provided a valuable foundation for assessment, planning and decision-making, supporting improved ecosystem-based management protection. Iterative progress been made in overcoming challenges faced by developing countries, especially the inaccessible realm. Our aim is report on produce improve national map guide other countries facing similar challenges, illustrate impact of even simplest map. produced...
Scientific working groups bring together experts from different disciplines and perspectives to tackle the "wicked problems" facing natural systems society. Yet participants can feel overwhelmed or inadequate in within academic environments, which tends be most acute at early career stages people systematically marginalized backgrounds. Such feelings block innovation that would otherwise arise gaining full spectrum of unique perspectives, knowledge skills a group. Drawing on personal...
The International Union for Conservation of Nature (IUCN) estimates that over a third all chondrichthyan species (sharks, rays and chimaeras) are threatened with extinction, primarily by overfishing (as target or bycatch species). Owing to the wide-ranging distributions many chondrichthyans, they often overlooked in marine protected area (MPA) design. South Africa is biodiversity hotspot diversity, improve conservation status these country's continental exclusive economic zone (EEZ), we...
Abstract Accurate assessments of ecosystem condition are needed to inform management processes such as systematic conservation planning and protected area expansion, marine spatial other effective area‐based measures.
