Research

Seagrass Ecosystem Research

Benjamin’s research is primarily focused on seagrass ecosystems and their associated fisheries. His PhD investigates the linkages between biodiversity and people using seagrass meadows as a model social-ecological system. He’s interested in these linkages more broadly to provide evidence for policy change across the Indo-Pacific that gives priority to seagrass meadows for the services they provide to people (e.g. livelihoods & food security), but also for measures that contribute to sustainable development (poverty reduction). Ben has been working with seagrass ecosystems for over 7 years and conducted seagrass associated research in Indonesia, Malaysia, Sri Lanka, Myanmar, Cambodia, Thailand, Tanzania, Mozambique, Mauritius, Mexico and the United Kingdom.

His work also incorporates the conservation concerns of small-scale seagrass fisheries more broadly, including the by-catch (in terms of fish) implications of some fishing strategies and issues associated to destructive gear use (e.g. mosquito net fisheries).

Ben’s work has been featured in various popular science and public news media channels such as the BBC and National Geographic and he regularily contributes to The Conversation. 

Ben’s PhD is supervised by Associate Professor Johan Eklöfand co-supervised by Lina Mtwana Nordlund(Uppsala University), Maricela de la Torre Castro(Stockholm University), Richard Unsworth(Swansea University) and Leanne Cullen-Unsworth (Cardiff University).

Ben is also a coordinating member of the Indo-Pacific Seagrass Network (IPSN).

 

Citizen Science

Ben is a co-developer of SeagrassSpotter, an entry-level citizen science project. Established in 2016 in the UK, the project uses a smartphone app and website database as its platform and facilitates a participants’ ability to spot seagrass and upload geo-tagged photographs that include information about seagrass presence, condition and whether people are using it in any way (e.g. fishing). Expanding across Europe in late 2016, and Globally in 2018, the project has accumulated over 2500 sightings from nearly 100 countries and engaged over 1500 users.

 

Biography

Ben obtained a B.Sc. in Marine Biology at Swansea University where he went on to obtain an M.Res. in Aquatic Ecology and Conservation. His master's thesis focused on the role of seagrasses as indicators of change in the British Isles where multiple characteristics were used to assess how seagrasses responded to varying degrees of anthropogenic stress. The publication that followed was featured in the News at a glancesection of Science.

During his masters, he co-founded the marine conservation charity Project Seagrass. Project Seagrass aims to conserve seagrass ecosystems through education, influence, research, and action. As director, he focuses on working to enhance understanding of the importance of seagrass using creative design to communicate scientific research to the wider public, as well as communicating this directly through workshops and events.

Ben’s previous work has focused on examining the factors that affect seagrass growth and he was involved with the Zostera Experimental Network (ZEN) to examine these factors. Other experience lies within the use of Baited Remote Underwater Video (BRUV) to assess fish abundance and diversity across multiple habitats in the Indian Ocean. Since 2015, his work has focused on how seagrass meadows provide food security.

More recently, Ben has been involved as a technical expert in development of The Dugong and Seagrass Research Toolkit (developed in collaboration by Total, Total Abu Al Bukhoosh, the Environment – Agency Abu Dhabi and the Convention on Migratory Species Dugong MOU; http://www.conservation.tools) and as a scientific advisor in the development of BBC’s landmark series Blue Planet 2.

    Seagrass meadows are an important wetland habitat that have been degraded globally but have an important carbon storage role. In order to expand the restoration of these productive and biodiverse habitats methods are required that can be used for large scale habitat creation across a range of environmental conditions. The spreading of seagrass seeds has been proven to be a successful method for restoring seagrass around the world, however in places where tidal range is large such methods become limited by resultant water movements. Here we describe and test a method for deploying seagrass seeds of the species Zostera marina over large scales using a new, simple method Bags of Seagrass Seeds Line (BoSSLine). This method involved planting seeds and sediment using natural fiber hessian bags deployed along strings anchored onto the seabed. When deployed in a suitable environment 94% of bags developed mature seagrass shoots, unfortunately one site subjected to a large storm event resulted in sediment burial of the bags and no seed germination. Bags were filled with 100 seeds with each leading to the development of 2.37 +/- 2.41 mature shoots (206 +/- 87 mm in length) 10 months after planting. The method was proven successful however the experiments illustrated the need to ensure habitat suitability prior to their use. Low seed success rate was comparable to other restoration studies, however further trials are recommended to ensure ways to improve this rate. In conclusion, this study provides evidence for an effective, simple method Bags of Seagrass Seeds Line (BoSSLine) for deploying seeds of the seagrass Zostera marina over large scales.

    Malaria is a serious global health issue, with around 200 million cases per year. As such, great effort has been put into the mass distribution of bed nets as a means of prophylaxis within Africa. Distributed mosquito nets are intended to be used for malaria protection, yet increasing evidence suggests that fishing is a primary use for these nets, providing fresh concerns for already stressed coastal ecosystems. While research documents the scale of mosquito net fisheries globally, no quantitative analysis of their landings exists. The effects of these fisheries on the wider ecosystem assemblages have not previously been examined. In this study, we present the first detailed analysis of the sustainability of these fisheries by examining the diversity, age class, trophic structure and magnitude of biomass removal. Dragnet landings, one of two gear types in which mosquito nets can be utilised, were recorded across ten sites in northern Mozambique where the use of Mosquito nets for fishing is common. Our results indicate a substantial removal of juveniles from coastal seagrass meadows, many of which are commercially important in the region or play important ecological roles. We conclude that the use of mosquito nets for fishing may contribute to food insecurity, greater poverty and the loss of ecosystem functioning.
