Week 2 Agenda
Monday 5 August (Fleischmann Building)
| 08:30-09:25 | Will Weider, Soil Decomposition Soils store the largest terrestrial carbon pool, but this critical resource that simultaneously supports agricultural productivity is vulnerable to environmental change.

| 11:35–12:30 | Rosie Fisher, Community dynamics and climate In models and in the real world, ecosystem function and diversity has huge impacts upon system resilience to climate changes. Despite this, ecological science has (unsurprisingly) produced no consensus on how the complexity of plant life should best be represented. In this lecture we review the existing, emerging and cutting-edge methods for representing ecosystem competition, coexistence and diversity, and discuss the merits and potential biases of alternative approaches.
