Welcome to the Funk Lab

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

Fitz and Funk publish a new book chapter on “Genomics for Genetic Rescue”!

Hypothetical scenario of a fragmented species that would likely benefit from gene flow augmentation (A) in which a species from a previously continuous distribution (outlined in grey) now exists in isolated populations (black circles) along an environmental gradient. Several small populations outlined by red dashes have already gone extinct. Extant populations range in inbreeding coefficient (F) and genome-wide heterozygosity (B). Neighbor-joining trees (C) using non-outlier versus outliner marker sets show different patterns of population similarity.

Sarah Fitzpatrick and Chris‘ book chapter on “Genomics for Genetic Rescue” has been published as part of the Population Genomics book series edited by Paul Hohenlohe. Genetic rescue, in which the infusion of new genetic variation increases population growth, has successfully reversed population declines in several iconic species. However, genetic rescue is rarely used in management due to concerns over outbreeding depression and genomic swamping. The goal of this chapter is to explain how genomics can improve implementation of genetic rescue, so that it can be used more effectively to reverse declines and extinctions of threatened and endangered populations.
