Welcome to the Funk Lab

We strive to understand the ecological and evolutionary mechanisms that generate and maintain biological diversity using population genomics, experimental manipulations, and field studies. Our goal is to not only test basic ecological and evolutionary theory, but also directly inform policy and management decisions that will ultimately determine the fate of biodiversity.



John Kronenberger’s manuscript on the effects of divergent immigrants on small populations accepted in Animal Conservation!

John Kronenberger, guppy biologist extraordinaire, taking shelter from the rain while sampling guppies in Trinidad.

A paper by John Kronenberger, Chris Funk, Jedidiah Smith, Sarah Fitzpatrick, Lisa Angeloni, Dale Broder, and Emily Ruell has been accepted for publication in Animal Conservation! Augmenting threatened populations with immigrants from elsewhere can be a valuable conservation strategy, but when immigrants have been long isolated from the target population or are adapted to different environments, they may cause more harm than good. In this paper, John and colleagues present results from a laboratory experiment in which small populations of Trinidadian guppies were augmented with immigrants from either an adaptively divergent or a genetically divergent source. Populations receiving immigrants fared better demographically than controls with no immigrants, suggesting that augmentation can be a valid tool even if only divergent immigrant sources are available. This project is part of our NSF-funded guppy grant.
