Want to work with a top-notch team of scientists to understand how diverse tropical forests will be affected by climate change? Are you a whiz with complex biogeochemical or ecological datasets? Interested in improving how ecology is represented in Earth system models? ¿Hablas Español? If you’ve got your PhD in hand or will have it soon, we’re looking for you! Apply now to be an NGEE Tropics Postdoctoral Scholar.
Congratulations to Meredith Jabis for filing her dissertation! This hard won accomplishment is just the start. She has a paper in review and two more in development, with ambitions to expand her analyses of GLORIA (Global Observation Research Initiative in Alpine Environments) data from RMBL and other sites in the Western US.
Postdoc Tom Powell just published a terrific new paper in New Phytologist! He used the ED2 vegetation demographic model to show how hydroclimate variability contributes to tropical forest functional diversity, which in turn makes forest biomass resilient to many drought scenarios. This is exciting work for a number of reasons: 1) Tom developed model parameterizations that allow coexistence of tree functional types competing for both light and water in a tropical forest, 2) the modeled forest structure and dynamics meet benchmarks collected over many years at Barro Colorado Island, Panama, and 3) the predictions suggest that compensation by co-occurring trees can buffer drought impacts on aboveground biomass — except if the dry seasons become much drier.
A new paper from our climate change experiment is just out! It shows that establishing limber pine seedlings host a different microbiome in their shoot and root tissues than that found in mature trees. It also shows an increased abundance of bacterial taxa thought to have anti-fungal properties in their roots, particularly when we watered the seedlings. Dana Carper, a PhD candidate in collaborator Carolin Frank’s lab led the study.
Congratulations to Adam Hanbury-Brown and the rest of the ERG Masters class of 2018! Adam’s master’s thesis included an interactive web map with information on Roosevelt elk foraging, bedding and migration areas to support emerging efforts to study and manage elk populations in Northern California.
Former postdoc Erin Conlisk’s paper showing that low elevation populations and ecotypes can be critical to upslope expansion of subalpine trees with climate warming just came out in the January issue of Global Change Biology.
