Impacts of coral bleaching on reef fish abundance, biomass and assemblage structure at remote Aldabra Atoll, Seychelles: insights from two survey methods Open
Introduction Coral bleaching immediately impacts the reef benthos, but effects on fish communities are less well understood because they are often delayed and confounded by anthropogenic interactions. Methods We assessed changes in fish ab…

Sources of marine debris for Seychelles and other remote islands in the western Indian Ocean Open
Vast quantities of debris are beaching at remote islands in the western Indian Ocean, despite minimal or zero local sources of pollution. We carry out marine dispersal simulations, informed by observations, incorporating currents, waves, w…

An international assessment of the barriers influencing the effectiveness of island ecosystem management Open
Island ecosystems are disproportionally impacted by biodiversity loss and as such their effective management is critical to global conservation efforts. Practitioners world‐wide work to manage island sites and species to conserve them, but…

Growth rate and projected age at sexual maturity for immature hawksbill turtles and green turtles foraging in the remote marine protected area of Aldabra Atoll Open
Changes in marine ecosystems from human stressors, and concerns over how species will respond to these changes have emphasized the importance of understanding and monitoring crucial demographic parameters for population models. Long-lived,…

Long-term changes in adult size of green turtles at Aldabra Atoll and implications for clutch size, sexual dimorphism and growth rates Open
Around the world, declines in the mean size of nesting sea turtles have been reported with concerns of a concomitant decrease in the reproductive output of populations. Here, we explore this possibility using long-term observations of gree…
