Making predictions in a changing world: The benefits of individual-based ecology [PDF]

open access: yes, 2015
Ecologists urgently need a better ability to predict how environmental change affects biodiversity. We examine individual-based ecology (IBE), a research paradigm that promises better a predictive ability by using individual-based models (IBMs) to ...

The case for long range chemoreceptive piloting in Chelonia [PDF]

open access: yes
The reproductive ecology and migration habits of Chelonia are investigated. Efforts were made to determine if the turtle navigates by chemoreception and if sensory responses of the migrating animals could be electronically tracked through telemetry ...
