Hello Everyone,

Please join us *Today Feb. 7* for this week's Enviro-Lunch talk by Nicholas
Dove, at 12-1pm in room *SE2-224*.



*Understanding the long-term temperature response *

*of soil respiration with microbial ecology*



While soils store [~1500 Pg] of carbon (C), it is currently unclear how
climate change will affect this large C pool. The effect of temperature on
enzyme kinetics predicts that as temperatures warm, microbial activity and
cellular respiration will increase, releasing C from soils into the
atmosphere. However, the long-term effect of warming on soil likely impacts
a myriad of factors affecting the persistence of soil C. Recent evidence
from a 20-y warming experiment suggests that soil respiration responds
non-monotonically to warming over time; although, the mechanistic factors
for this have yet to be elucidated. We used a 4.5 y whole-profile soil
warming experiment coupled with laboratory incubations amended with
different resources to show that soil microbial communities in warmed soils
have altered nutrient demands, which profoundly impacts their community
composition and metabolism. These differences could account for previously
unexplained patterns, and these insights could help constrain predictions
for soil C persistence in a warmed world.



*Bio: *I am broadly interested in the effects of global change
(particularly changes in climate and fire regimes) on soil microbial
communities and the biogeochemical processes that they control. I pair
traditional biogeochemical assays with next-generation high-throughput
sequencing of microbial DNA and metagenomics to understand linkages between
microbial community structure and function. I am in Stephen Hart's
Ecosystem Ecology Lab and an affiliate of Lawrence Berkeley National Lab
(formerly a Dept. of Energy Graduate Student Research Fellow), and much of
my research takes place in the Southern Sierra Critical Zone Observatory.



When: Thursday 2/7, 12pm – 1pm



Where: SE2-224



Coffee will be provided, please bring your own mugs.



We look forward to seeing you,



Jing & Jennifer
