Why don't we use behavioural ecotoxicological studies in environmental management? Michael Bertram & colleagues assess whether behavioral measures are relevant at the population level. They conclude that, yes, they are and they are underutilised. doi.org/10.1021/acs....

Bumbles are my favorite bees

I have been a beekeeper and would like to be again, but getting beehives to 'Save the bees!' is like a sheep farm to support biodiversity. You can do it well and it can have positive impacts, but more domesticated animals won't save wild populations (don't @ me about sheep, struggled for metaphor)

Federal Cuts To Research Could Contribute To Recession, Study Finds Wide-spread reductions in funding for scientific research could result in economic losses similar to the loss in GDP during the Great Recession, according to a new study.

"The administration’s wide-spread reductions in funding scientific research could result in economic losses comparable to the decline in GDP during the Great Recession of 2009, according to a new study by a team of economists at American University’s Institute for Macroeconomic and Policy Analysis."

Happy #WorldWildlifeDay. A friendly reminder that livestock cannot replace native biodiversity, despite what you may have heard.

The NIH overhead cut doesn't just hurt universities.

It's deadly to the US economy.

The US is a world leader in tech due to the ecosystem that NIH and NSF propel. It drives innovation for tech transfer, creates a highly-skilled sci/tech workforce, and fosters academic/industry crossfertilization.

Figure from a paper - legend: Figure 2. Measuring changes in insect biodiversity can be achieved by focusing on drivers that directly or indirectly impact insect biodiversity metrics and trends (left). Where data on insect populations specifically are unavailable, data from other species and ecological processes can provide inferential support for changes in insect biodiversity (right).

We're having a discussion about which interesting animal behaviour would be terrifying on a different species. The rules are

a) it can't be an immediate danger to you
b) it has to be so scary you would stop filming and leave.

Feel free to play along. The current winner is vulture murmuration.

Bees remain heat tolerant after acute exposure to desiccation and starvation Summary: Sublethal desiccation exposure and short-term starvation do not significantly affect heat tolerance in honey bees and sweat bees.

An inspirational study that everyone interested in the thermal ecology of bees and their responses to environmental warming should read. I'll most likely borrow some of the elegant methods used here, and put them to work with some wild bees next summer 😉

Chart of predicted extinction risk vs rise in temperature vs pre-industrial.

Shows risk rising from somewhere around 2% today to almost 30% somewhere around 5.5°C.  The rise is not linear, and increases sharply after 2°C of warming.

Chart of predicted extinction risk vs rise in temperature vs pre-industrial. Shows risk rising from somewhere around 2% today to almost 30% somewhere around 5.5°C. The rise is not linear, and increases sharply after 2°C of warming.

Every tenth of a degree of warming matters; extinction risk goes up pretty sharply, with almost 30% of species being lost if we go on a fossil fuel burning binge instead of leaving them in the ground.

Top Panel: pale blue background, temperature reads "24°C/ 75°F" A Bumble bee makes two visits to small flower patches.  Text Reads:  More journey's, longer visits, fewer flowers, slower flights. 
Bottom panel: pale red background, temperature reads "32°C/90°F" A bumble bee makes a journey to a large flower patch.  Text reads:  Fewer journeys, shorter visits, more flowers, faster flight.

Advent Sci-Fact 7:

Heat Impacts Bumblebee Foraging!🐝

Bees at higher temperatures had lower metabolic rates, but made fewer, faster visits to many flowers, compared to bees at lower temperatures. Researchers believe this may be due to heat stress.
