Barnacle Competition Connell's 1961 classic competition
experiment is modeled. you can explore the fundamental and realized
niches of two species of barnacles, Chthamalus and Balanus.
One species can grow at a wider range in depth but can be outcompeted,
while the other species is limited to deeper rock. You can also cause
sea level to change simulating global warming.
|Microcosm is a simulation which draws upon Gauss' (1934) classic experiments with protists. In this virtual petri dish, you can add bacteria, two species of Paramecium, and a predator. The two Paramecium (P. aurelia & P. bursaria) species compete for resources. One of the species is a better competitor for bacteria, while the other has photosynthetic endosymbionts and can utilize light. Both species are preyed upon by Didinium.|
