Mean annual temperature shapes N cycling and fine root nutrient foraging across a Hawaiian tropical elevation gradient
Abstract: Increasing mean annual temperature (MAT) due to global climate change has been shown to drive carbon (C) cycling and primary production in a range of forest ecosystems. The mechanisms underlying this relationship are not well resolved, but are likely related to changes in belowground resource availability and forest nutrient limitation. We examined potential mechanisms across a 5.2°C tropical montane wet forest elevation/MAT gradient on the island of Hawaii. Our results suggest that nitrifier communities respond to increasing MAT in ways which increase N bioavailability, and potentially lead to increased phosphorus demand at higher MAT.

Biography: Suzanne studies how changing environmental conditions affect the cycling and availability of nutrients to terrestrial plant communities, and aims to understand how these nutrient dynamics feedback to the fates of terrestrial carbon. She currently focus on how temperature affects microbial-community and ecosystem nitrogen and carbon dynamics across natural environmental gradients.
