Good morning all,

This is a friendly reminder that we have an Enviro-Lunch seminar today.
Hope I see you there!

Best,
KJ

Hello all,



Next Monday (4/25) Dr. Daniel Zuleta from Smithsonian Tropical Research
Institute will present his research on forest mortality. Please join us
between 12-1 pm (pacific) via zoom.

*Title:* Tree mortality and unaccounted carbon losses in tropical forests

*Abstract*: Despite the widely recognized role of tropical forests in the
global carbon cycle, large uncertainties remain on how they will respond to
ongoing climate change. This uncertainty is largely attributed to spatial
variation in woody residence times (i.e., tree mortality), which occur more
abruptly compared to tree growth and recruitment. But the drivers and
mechanisms of tree mortality are poorly understood. Here, I discuss the
main challenges of studying tree mortality and present current advances
from the Forest Global Earth Observatory (ForestGEO
<https://forestgeo.si.edu/>) monitoring program in the tropics. I present
results on the relative importance of multiple tree-level factors involved
in tree death, their physiological consequences, and their implications for
aboveground biomass dynamics.

*Bio: *Daniel Zuleta is a Postdoctoral fellow working on tropical forest
mortality with ForestGEO <https://forestgeo.si.edu/> and NGEE–Tropics
<https://ngee-tropics.lbl.gov/>. His current research focuses on
understanding the mechanisms driving tropical tree mortality to improve
predictions of forest response to environmental changes. Daniel is one of
the PIs of the Amacayacu Forest Dynamics Plot
<https://forestgeo.si.edu/sites/neotropics/amacayacu>, a 25-ha plot located
in the Northwestern Amazon, Colombia. As a postdoc fellow, he coordinates
the ForestGEO annual mortality and damage surveys, a pantropical program
that aims to collect tree-level data related to potential mechanisms of
mortality and forest biomass loss. He received his PhD in Ecology from
Universidad Nacional de Colombia (Medellín) in 2019.





Sincerely,
