Everything eats everyone?

One of the most important components of the soil is the biology within it; this abundant and diverse group is the driver of nutrient cycling, decomposition, bioturbation and pedogenesis (Figure 1) within soil ecosystems.  However due to the opacity of the soil, small size of the organisms involved and the diversity of species, understanding the interactions that are occurring is very difficult. Today Felicity Crotty explores methods to investigate the feeding methods of the vast biodiveristy in soil. 



Mapping biodiversity with environmental niche modeling

Maps of biodiversity at global and continental scales plays a pivotal role in ecology, evolutionary biology, and conservation biology.  Diversity maps give insight into the action of ecological and evolutionary processes at large scales, and they can guide management decisions.
