Research by this team has shown how seabird guano can enhance coral reef productivity, biodiversity, and how they work. The team are conducting this research in the Chagos Archipelago, Seychelles, and French Polynesia, incorporating into their study sites, islands with and without rats, and those with ongoing rat eradication programmes. The research will help inform tropical island conservation and restoration efforts all around the world.
Lead investigator: Prof. Nick Graham (Lancaster University).

Seabird nutrient subsidies enrich mangrove ecosystems and are exported to nearby coastal habitats
May 31, 2025
Appoo, Jennifer, 2025, "Seabird nutrient subsidies enrich mangrove ecosystems and are exported to nearby coastal habitats", https://doi.org/10.5061/DRYAD.0RXWDBS79, Dryad
In this study, we investigate how mangrove ecosystems respond to nutrient subsidies supplied by nesting seabirds. We first quantify seabird guano nutrient input and seabird guano nitrogen isotopes. We then assess the influence of seabirds on mangroves by comparing nitrogen, phosphorus, nutrient ratios and resoprtion efficiency in mangrove leaves sa...

Seascape configuration determines spatial patterns of seabird-vectored nutrient enrichment to coral reefs (dataset)
Apr 25, 2025
Stuart, Courtney E.; Pittman, Simon J.; Stamoulis, Kostantinos A.; Benkwitt, Cassandra E.; Epstein, Hannah E.; Graham, Nicholas A.J.; Smith, Andrew C.; Lacey, Jack H.; Bistolas, Kalia S.I.; DeVore, Jayna L.; Ducatez, Simon; Wedding, Lisa M., 2025, "Seascape configuration determines spatial patterns of seabird-vectored nutrient enrichment to coral reefs (dataset)", https://doi.org/10.7910/DVN/5NHHEY, Harvard Dataverse, V1
Pelagic-feeding seabirds deliver nutrient subsidies that enhance the productivity, biodiversity, and resilience of terrestrial and marine ecosystems, particularly in nutrient-poor tropical environments. However, the biogeophysical variables governing the fluxes of these nutrients within and among interconnected ecosystems remain poorly understood....

Data on the carbon (ð13C) stable isotopes, nitrogen (ð15N) stable isotopes, nutrient levels (percent nitrogen, %N), and nutrient ratios (carbon-to-nitrogen ratios, C:N) of taxa collected from two depths within lagoonal reefs and from more exposed seaward reefs within the Chagos Archipelago, including from reefs surrounding islands where high densit...
