Tropical Mountains and Forests: Understanding Processes and Interactions between Land, Atmosphere, Plants, and Water Across Disciplines

Session ID#: 78865

Session Description:
Tropical mountain systems are of great importance for global biodiversity, carbon cycling, and climate regulation and yet they remain poorly understood due to spatiotemporal heterogeneity in patterns and processes. Terrain-atmosphere interactions diversify environmental gradients and support unique ecosystems along mountain slopes. Plant functioning interacts with the physical environment, shaping biogeochemical, ecohydrological, and atmospheric processes across micro- to regional-scales. Building a comprehensive understanding of these dynamics requires researchers to account for scaling issues and to integrate across academic disciplines.

This session welcomes studies exploring processes and interactions of tropical mountains across all scales, elevations, and ecosystems, especially those studies with interdisciplinary components. Examples of appropriate topics include direct and indirect anthropogenic ecosystem and climate changes, and their impacts on water-carbon cycling; orographic cloud and precipitation, and their ecohydrological significance in tropical montane forests; experiments utilizing natural gradients; and landscape connections through airflow or water movements between mountains and lowland or oceans.
