Why are there more of some types of species than others?

Biodiversity is uneven both across geographic regions and branches of the tree of life. In this talk, I will explore one possible cause for this pattern: variation in the rate at which new species form. Using a data set from lizards and snakes, I will discuss the possible factors influencing speciation rate variation.

Note: this talk was not recorded at the request of the speaker.

Plant physiology, forest ecology, and carbon cycle uncertainty in a changing climate

Widespread tree mortality following disturbances such as droughts, fire, and pest and pathogen outbreaks has emerged as an environmentally and economically devastating ‘ecological surprise’. Increases in disturbance-driven tree mortality with further climate change has the potential to massively disrupt terrestrial ecosystem productivity and biodiversity, causing Earth’s forests to release carbon into the atmosphere.
