Predicting the threat from invasive non-native species in British Overseas Territories

Last month, I led a team of ecologists who met in St Helena, a volcanic tropical island in the South Atlantic Ocean, to collaborate with invasive species experts on the mid and south Atlantic UK Overseas Territories. Together we are working to predict and prioritise those non-native plant and animal species most likely to present a threat to existing ecosystems, human health and the economy on the island, as well as developing Pathway Action Plans to inform the already incredible work of the local biosecurity teams.

Predictions and priorities to prevent new invasive non-native species arrivals

CEH ecologists are contributing to international efforts to strengthen biosecurity in the British Indian Ocean Territory. Prof Helen Roy explains more...

A magical and remote atoll, the British Indian Ocean Territory (BIOT) comprises extensive coral reefs and unique terrestrial habitats. Not only does BIOT host the Indian Ocean’s largest breeding colonies of the red-footed booby Sula sula, but also high densities of coconut crabs and endangered hawksbill and green turtles.

Caribbean workshop focuses on invasive alien species

Professor Helen Roy reports back from a workshop that she led alongside Centre for Ecology & Hydrology colleagues Jodey Peyton and Dr Oli Pescott on Grand Cayman last week. The event's purpose was to determine which invasive alien species were likely to arrive, establish and impact on biodiversity, ecosystems, human health and the economy across the Caribbean UK Overseas Territories within the next 10 years.

Why are ladybirds entering homes in large numbers?

There has been a flurry of news items on ladybirds in recent weeks. Much of the focus has been on the harlequin ladybird and the way in which this species moves into houses for the winter months.

Autumn and winter can be an adverse time for ladybirds (and other insects) because of low temperatures and lack of food; ladybirds become dormant.

Sharing an enthusiasm for citizen science (and ladybirds) across the world

Chile has incredible appeal for ecologists. The Andes extend alongside the eastern edge of Chile and essentially render it isolated from the rest of South America. Not surprisingly the landscapes of this long and narrow country are extremely diverse and the biodiversity even more so. The species list for Chile includes around 31,000 species and about 37% of these are endemic. Justifiably Chile is considered a global biodiversity hotspot.
