The Laboratory of Coevolutionary Biology
Coevolution organizes these species into complex webs:
predators and prey, hosts and parasites, competitors, and mutualists.
The result is what Darwin called the Entangled Bank.
Others call it the Web of Life.
Our research goal:
How and why has the web of life become so entangled?
How does coevolution shape webs of interacting species across space and time?
What ecological and genetic conditions allow interactions to persist?
Relentless Evolution (2013):
Why do species evolve relentlessly, even when they seem fairly well adapted to their environments?
Over short time scales, how do species, and interactions among species, evolve in nature?
How do the apparent patterns of relentless evolution differ over short and long time scales?
The Geographic Mosaic of Coevolution (2005):
How does coevolution shape interactions among species across ecosystems, regions, and continents?
Why does the geographic mosaic of coevolution differ among different forms of interaction -- e.g., mutualistic interactions, competitors, parasites and hosts?
The Coevolutionary Process (1994):
Why does natural selection favor some species that interact with only a few species and other species that interact with many species?
Why do interactions among species evolve, and sometimes coevolve, in different ways in different environments?
How does the history of evolutionary ecology and coevolutionary biology help us understand our current hypotheses and predictions?
Interaction and Coevolution (1982; reissued 2014):
Why does natural selection act differently on different forms of interaction among species?
Can we develop general principles about the coevolutionary process?
