New open access paper out now in @NatureEcoEvo! We found that invasive rats on islands directly impact the aggressive behaviour of territorial damselfish. 🧵⤵️

This atoll, a marine protected area, had been the only place in the Mexican Caribbean without showing the presence of this #SCTLD disease, until now. https://t.co/q0VeQmkL6l

When rats invade tropical islands, they can trigger a chain reaction that reverberates all the way to coral reefs, researchers say. https://t.co/jb0Adz6FJ5

[Quirks & Quarks @CBCQuirks]

A new study revealed a surprising link between rats and damselfish. The fish feed on algae, which are fertilized by bird poop - and there is less of it, thanks to egg-eating rats on the ground.

The presence of invasive rats on islands can lead to behavioral changes in offshore coral reef fish. Scientists found that damselfish have larger territories that they defend less aggressively on reefs near rat-infested islands, reports @johnccannon.

Invasive rats topple ecological domino that affects reef fish behavior https://t.co/3SJwCI8oWB

[The Conversation @ConversationUK]

Black rats arrived on the Chagos Archipelago on ships in the 18th century.

Since then, these invasive rats have been changing the ways fish behave.

And this behavioural change may alter the wider coral ecosystem.

🐟 Invasive rats on tropical islands are affecting the territorial behaviour of the Jewel Damselfish.

LEC Reefs researchers @RachelGunn5 and @SallyKeith have written for the Conversation about their research which shows how invasive rats are changing the behaviour of fish on nearby coral reefs @Sal_Keith @LecReefs @LancsUniLEC

[Nature Portfolio @NaturePortfolio]

A study from 10 islands in the Indian Ocean in @NatureEcoEvo finds that invasive black rats disrupted nutrients provided by seabirds, leading to a coral reef fish having larger territories and investing less time in aggression than on rat-free islands. https://t.co/ZvpbnKMDx2

[New Scientist @newscientist]

Invasive rat populations on tropical islands decimate populations of seabirds, due to their voracious appetite for eggs and chicks. Now we are learning that they change the behaviour of fish around the islands too https://t.co/6Vkk7YmmTs

New Scientist reports on a new study by Dr Rachel Gunn and researchers from @LecReefs into how invasive rats on tropical islands are affecting the behaviour of damselfish on nearby coral reefs @LancsUniLEC @Sal_Keith

[Natural History Museum @NHM_London]

These #fish won't tell you to get off their land🐠

Some damselfish tend to underwater algae 'farms', protecting it from competitors. However, when invasive #rats move in, they get much less protective.
