CLIMEX Match Climate Composite Match Index (CMI) overlaid with Tipuana tipu distribution location records, projected globally. Insets show the native range, part of South America, part of southern Africa, southwest Australia, and an area of eastern Australia with high levels of cultivation and/or naturalisation. Areas with an orange-red colour (CMI 0.8–1) had high CMI values. Areas with a blue colour (CMI 0.6–0.8) had a climate with moderate CMI values. Records of T. tipu are shown as open circles. Pink circles represent records of plants within the native range. All other colours represent plant records in the non-native range, with purple representing cultivated plant records, yellow representing non-cultivated plant records, green representing records with both cultivated and non-cultivated plants and brown representing plant records where the cultivation status was indeterminate.

The interplay between climatic niche and spatial distribution can inform the management of non-native invasive species. Our findings reveal that the invasion risk for species with small geographic ranges may be greater than assumed.

Fire responses of fauna in south-western Australia: clarifying some recent assertions Prescribed burning is commonly used to reduce wildfire risk, but it can also have negative impacts on biodiversity. A recent document raises concerns about

Apparently, "Most of the animal species and communities discussed suffer from inaccurate or incomplete reporting of fire responses"

AI error or not, Iran school bombing is a permanent stain on America’s soul | Will Bunch A debate on AI in warfare obscures the truth about an Iran school bombing. U.S. humans are to blame for this war crime.

They had names. They had beautiful faces. And they had the same dreams as your kids - crushed when American "precision" bombs slammed into their Minab elementary school, killing 175

Don't blame AI for this. Blame the sick humans who see war as a game

🌿 Postdoc opportunity in plant evolutionary ecology/genetics!

My lab in the Dept. of Ecology & Evolutionary Biology at the University of Michigan is recruiting a postdoctoral researcher to start Fall 2026.

We study plant adaptation, using weeds as model systems.

Indigenous Australians share the racist messages they receive online: β€˜No one’s feeling safe’ Australia has announced an inquiry into racism and hate directed at First Nations people, as Lidia Thorpe says racism has β€˜never been this bad’

Important read about the incredibly ugly racist hate, abuse & threats Indigenous Australians get

"Many noted a marked uptick in violent rhetoric since the failed voice to parliament referendum in 2023."

β€œA lot of people in general feel really comfortable being racist.” 1/

'ALL SHE WANTED WAS TO BE LOVED' - The RED HEART Movement ❀️HER NAME IS KELLY WILKINSON❀️

β€œThe domestic violence femicide of Kelly Wilkinson is more tangible evidence of how badly frayed our safety nets are.
Kelly begged police for help. They told her to give her abuser a break & to go β€˜cool off’. 9 days later, Earl Johnston burned Kelly alive. It was April 20, 2021. Kelly was only 27.”

There's a 90 min doc on Netflix called Careless about ageing in Australia.
It's made by Sue Thomson & centres around her mother's situation. Also features a few other older people, aged care activists, and journalists.
A very easy watch for a usually depressing topic.

Dichopogon capillipes

We are getting towards the end of a long, hot summer and there isn't much flowering in the Perth Hills at the minute, but these amazingly delicate flowers are one thing that you can see in the bush currently.
