New Science paper by Ohlert et al with a rainfall-exclusion experiment at 74 sites over the globe shows extreme droughts caused high productivity declines and low recovery, especially in drier locations with low plant diversity. science.org/doi/10.1126/scie…

Drought intensity and duration interact to magnify losses in primary productivity

As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with...

Our paper on trait diversity indices is out now in PLOS ONE! Great paper to share with the trait nerd in your life. journals.plos.org/plosone/ar… @MeghanAvolio @drcynthiacchang @phylofeast @ge54783 @hobbie_sarah @drkimkomatsu

The impact of trait number and correlation on functional diversity metrics in real-world ecosystems

The use of trait-based approaches to understand ecological communities has increased in the past two decades because of their promise to preserve more information about community structure than...

Productive and fun #DroughtNet discussions this week at @ucsb_nceas. Finally taking a close look at the multi-year drought data received (so far) from more than eighty sites around the world. Great support from @USLTER and @LTER_Net_Office.

Our paper on uncertainty in lichen critical loads is out in Ecosystems! I worked on this as part of my NSF INTERN fellowship with Air Program at the US Forest Service, but Rob Smith brought it home link.springer.com/article/10…

Across 100 sites globally, @DroughtNet found that extreme drought cut grassland production much more than might have been suspected. Science Magazine covered the group's first-year results presented at #ESA2022 by @CubanKate! Very relevant today. science.org/content/article/…

Scientists exposed plants to a yearlong drought. The result is worrying for climate change

Global experiment found ability of grasses and shrubs to store carbon suffered

This week we are hosting an @USLTER #SynthesisScience working group investigating the effects of extreme drought on terrestrial ecosystems around the world! 💧 They will be using experimental data from over 100 locations, including 8 LTER sites. #DataScienceDay2022

Dissertation submitted to my committee from the Johannesburg airport. A celebratory Dom Pedro following field work in South Africa. It's been a journey, but honestly a lot of fun.

I bought this bike two years ago. Since then, I’ve put more miles on it than my car. Looking forward to some upgrades this spring. Happy two years, buddy!

If you like community ecology half as much as I do, you will love this article about @MeghanAvolio's recent paper in @Ecology_Letters lternet.edu/stories/in-searc…

All plants are somehow affected by global change, but their responses are inconsistent between ecosystems, a LTER Synthesis group finds.
