Worms eat tree-killing beetle in research trial as scientists team up Researchers say a chemical trial and a biological trial using worms have shown early success in the fight against the shot-hole borer, which has led to the destruction of thousands of Perth's trees.

Researchers across the major universities in Western Australia working in partnership with government epitomise the multi-faceted approaches required to deal with shot-hole borer.

Street lamps aren’t the only form of artificial light pollution – here’s how to create darker nights Light Pollution is a significant environmental issue and is spreading rapidly. The good news is that it is easy to fix - find out how here…

Interesting research, suggesting poorly designed or excessive private lighting is contributing as much to ALAN pollution as street lights.
🌏🧪
This seems to be one of the few areas where our own actions can make a significant positive contribution!

Check out new #CEB paper by @gblackburn.bsky.social et al. that found that Western Australia magpies sing less when exposed to anthropogenic noise, but not necessarily louder. 🐦🚧
This may save energy, yet could cost social & territorial signals.

Western Australian Magpies alter the rate, but not the amplitude, of their territorial song in anthropogenic noise Anthropogenic noise is considered one of the most serious forms of pollution globally and has been shown to have negative effects on the distribution, behaviour, cognition and reproductive success of...

Another #PhD chapter out in the world! We investigate the impact of anthropogenic #noise on the territorial song of WA magpies 🔊🐦🔊

Our new paper, led by @gblackburn.bsky.social, finds a very sharp decline in the rate of carol calls (the main territorial call) given by magpies during anthropogenic noise, but no change in the amplitude. @dutourmylene.bsky.social

Climate-induced divergence of song - Nature Climate Change Vocal communication is essential for information transmission in many species, such as that related to mating opportunities or predator presence. Recent research revealing how phenotypic changes broug...

@gblackburn.bsky.social & I recently wrote this piece in Nature Climate Change about the potential conservation implications of climate-induced divergence of song. This may occur more often under a rapidly changing climate & cause greater isolation between popns.

Australia-first study finds rat poison in rare Perth Hills chuditch New evidence shows the first confirmed cases of rat poisoning in native Australian marsupial carnivores.

Great piece on our new research highlighting the severe impact of using second generation anticoagulant rodenticides. We are killing quolls snd Tasmanian devils when we poison rats. www.watoday.com.au/national/wes...

Lethal second-generation rat poisons are killing endangered quolls and Tasmanian devils Second generation rat poisons are so potent that they’re banned for home use in Europe and North America. But here, you can pick them up at Bunnings or Coles.

Thank you @dutourmylene.bsky.social !!!

Happy to share that today I started a #Postdoctoral #research fellow position at Central Queensland University working with Capricorn yellow #chats! 🐦 Very excited for this new adventure!
