Stronger and more frequent El Niño events are contributing to a decline in arthropod diversity and population, as well as to a reduction in the ecological services the animals provide.

I assessed whether non-native insect colonisation altered the population distribution of one case study island-endemic insect: Discophallus ascension of volcanic Ascension Island in the South Atlant...

Nature - Time-series data from tropical forests tracking weather and declines in arthropod diversity and function show that fluctuations in species were largely dependent on their El Niño...

Invasive animals threaten island-native arthropods with predation. We found that introduced ants and rats conducted 77% of experimental arthropod live bait predations on Ascension Island. Predation w....

Nature Reviews Biodiversity, Published online: 04 April 2025; doi:10.1038/s44358-025-00038-9Insect biodiversity in tropical forests is poorly understood but is probably facing declines, with serious consequences for ecosystem functions and services. This Review describes the major threats to insect biodiversity, which include the effects of a burgeoning human population and of climate change. The authors further highlight the urgent need for greater efforts to measure and monitor insect biodiversity in the tropics and discuss emerging approaches to facilitate such studies.

Tiny habitats of tiny species: the importance of micro-refugia for threatened island-endemic arthropods

Moths are the most taxonomically and ecologically diverse insect taxon for which there exist considerable time-series abundance data. There is an a...
