Carnivores highly active during the day were the first to go extinct after human arrival and settlement globally. Their complex life histories made them most vulnerable to habitat alteration and very salient hunting targets.

They were multiply imputed 20 times based on 22 traits of 134 species (i. e. our whole sample) and the whole dataset had ~21% missing values. Values of closely related species would have been drawn preferentially by the algorithm (pmm with mida's touch), but not always.

Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.

Extinct Pleistocene carnivores were diurnal and highly active There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, t...

BMR is a major but often overlooked confound of all traits previously proposed to be related to carnivore extinction during the Pleistocene in the context of the overkill hypothesis. We looked at 22 eco & LH traits in a sample of 120 extant and 14 extinct species from every biogeographic realm.

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Undue Influence: oil and gas giants infiltrate Australia's Bureau of Meteorology - Michael West Oil giants Shell, Santos, Woodside and Chevron finance the Bureau of Meteorology. The BOM does not discuss "climate change".

Public info institution the BoM never mentions fossil-fuelled global heating, even during mega-droughts, heatwaves, bushfires floods. Why? Perhaps because its board is controlled by Shell, Santos, Woodside & Chevron?

If you think this stinks, make a subsmission!

Human impacts on large mammals went well beyond triggering late Quaternary mass extinctions. A new paper by Brook et al. showing that biogeographic patterns were erased by the spread of domesticated species:

Despite broad uptake, metascience and the Open Science reform movement have garnered ample criticism. Such criticism is also known as critical metascience. We will reflect on central critiques by bringing together key voices from a variety of disciplines, asking what needs to change, how and why?
