One farmer saved $7,000 on fertilizer while increasing crop yield & protecting pollinators. Could be so powerful for places it scales well.

There's a great shoutout to our paper showing that we've lost a quarter of all butterflies in the last two decades www.science.org/doi/full/10....

Great story! Learning to identify butterflies is in reach. Counts by thousands of people make up the best long term data 🦋 And there are practical means to forestall rapid butterfly decline. Thank you @margaretrenkl

More bad news for butterflies. Our new paper led by Wendy Leuenberger shows common species are declining even more rapidly than rare ones. @ZipkinLab

How does climate impact our gut microbiomes? As it turns out, there are many ways. KBS researcher Elena Litchman has studied the relationship between climate and our gut microbes. She contributed to a wide-ranging article recently published in Time Magazine.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.
Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

▪️Muestra que los paisajes fragmentados tienen menor diversidad alfa y gamma

Important study from Gonçalves-Souza et al:

- Finds that fragmented landscapes have both lower α and γ diversity.

- Refutes claims that fragmentation can increase biodiversity in the landscape.

- Emphasizes the need to restore habitat and increase connectivity.
