  The theme covers a spectrum of environments, with research focusing
on microbial populations in desert soils, the impact of climate change on desert birds, the use of mountain ants as bioindicators of temperature change, and soil erosion as a critical environmental issue. Mathematical modelling can be used to test assumptions relating to ecological processes, such as the Allee effect and critical survival thresholds. The theme also includes the latest research on the effects of environmental change on marine mammals, and the coexistence of two species of differing lifespan and body size and how they organise their reproductive biology in unison with the changes in day length and temperature.
