Stronger El Niños reduce tropical forest arthropod diversity and function 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...

New article out today in Nature - intensified El Niño events under climate change appear to be chipping away at tropical forest arthropod diversity.

This is already leading to substantial losses in arthropod function in primary forests across the tropics.

Invasive Big‐Headed Ants and Black Rats Are Dominant Arthropod Predators Across Opposing Habitats of a Degraded Oceanic Island 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....

We leashed arthropods like little dogs on leads! Why? To quantify which invasive predators are attacking arthropods, and where, on an Atlantic island 🏝️🐜🐀

The Daintree Rainforest Observatory in Queensland Australia is without a doubt one of the coolest research sites I’ve visited. The team there have been using the full-sized research crane to position our insect traps in the tree canopy! A peculiar/amazing sight in the middle of the rainforest 🌴🌳🏗️🌴🌳

Causes and consequences of insect decline in tropical forests 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.

New online! Causes and consequences of insect decline in tropical forests

Tiny habitats are important for island-endemic arthropod conservation! Especially caves, isolated pools, sea stacks and high-elevation patches of native vegetation. These "micro-refugia" from threats may be feasible targets for first steps in local management. Open access :)

Please can you add me!

A little bit of the organised chaos of arthropod life at Chiang Mai Museum of World Insects and Natural Wonders

I would sincerely love to stand before the nurses of Chicago and enthusiastically present on desert island nematodes

New open-access research! Nematodes are super cool, and we prove it on an isolated desert island.

We found near perfect turnover in trophic group along a vegetation/elevation gradient. We also warn that root-parasitic nematodes seem to spread with non-native vegetation.

Cordyceps fungus growing out of weevil in Cusuco National Park, Honduras

Here's an #entomology Christmas tree to start December with!

ATBC 2025 in Oaxaca, Mexico - is anybody aiming to attend and present on #climatechange impacts (or lack of) on #insect #ecology or #biodiversity? We at the Uni of Hong Kong (‪@louiseaashton) are gauging interest outside of our usual circle to see if it's worth proposing a symposium. Pls share!

hi everyone! My first post is the excellent news that I've been give tenure! Really excited to continue to work with an excellent team of scientists in the biodiversity and environmental change lab (www.louiseashton.net) and grateful for all the support from my mentors and peers.

Thanks!

Hello! I research species invasions on Ascension in the South Atlantic

A highlight of living in Hong Kong is having these Critically Endangered Yellow-Crested Cockatoos diligently tearing bits off the outside of your apartment, I guess

Followed, thanks!

Doesn’t have one yet :) but the genus is Niambia

A new species of Niambia woodlouse known only from inside turtle nests on Ascension Island.

Greetings from Hong Kong! Looking forward to chatting #entomology, #ecology and #conservation with you all.

Here's a new species to science to say hello: a desert-island woodlouse known from inside turtle nests..! From recent work on remote Ascension Island 🏝️
