Resurrecting the ghost of competition past with dormant zooplankton eggs.
A common prediction of evolutionary theory is that the strength of interspecific competition should decline over time among sympatric populations of competing species. Here we provide experimental evidence of historical declines in competition effects among competing zooplankton populations. Using diapausing eggs, we resurrected clones of three species of zooplankton obtained from different per...
متن کاملResurrecting the Dead (Molecules)
Biological molecules, like organisms themselves, are subject to genetic drift and may even become "extinct". Molecules that are no longer extant in living systems are of high interest for several reasons including insight into how existing life forms evolved and the possibility that they may have new and useful properties no longer available in currently functioning molecules. Predicting the se...

We introduced the Resurrecting Duckling security policy model to address this problem. Master-slave relationships, however, do not exhaust the range of interesting interactions. We th...

متن کاملResurrecting dead-water phenomenon
We revisit experimental studies performed by Ekman on dead-water (Ekman, 1904) using modern techniques in order to present new insights on this peculiar phenomenon. We extend its description to more general situations such as a three-layer fluid or a linearly stratified fluid in presence of a pycnocline, showing the robustness of dead-water phenomenon. We observe large amplitude nonlinear inter...
