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.

Historic guppy transplant experiments in Trinidad provide a replicated test of the balance between selection and gene flow in nature, revealing that adaptive traits are maintained in the face of high gene flow

IMG_1213 Sarah Fitzpatrick (PhD candidate), Lisa Angeloni (Associate Professor), Jill Gerberich (REU student), John Kronenberger (PhD student), and Chris Funk (Associate Professor) set out to the streams of Trinidad to investigate the impacts of previous transplant experiments where Trinidadian guppies were moved from stream localities with many predators into upstream tributaries with few predators. Guppies from these introduced populations have provided one of the best examples of rapid adaptation in the wild. But until now, the impact of the non-native guppies, as they get washed downstream and interact with native populations, was unknown.

Using genetic markers, our team found that the genetic signature of introduced guppies swept to long downstream distances, indicating high levels of gene flow downstream from all introduction sites on a rapid timescale. However, despite genetic uniformity caused by introductions, guppies maintained phenotypic traits that best allowed them to survive and reproduce, given their local predator community. In other words, genetic homogenization did not cause the loss of locally adapted phenotypes.

Chris’ first Ecuador study abroad class a huge success!

20140616_Black_howler_1_croppedMantled howler monkey (Alouatta palliata) on Ecuadorian coast. Chris’ first Ecuador study abroad course in June and July 2014 was a huge success. CSU undergraduate students visited many of Ecuador’s diverse habitats (lowland Amazonian rainforest, cloud forest, páramo, coast); learned how to conduct field research; and got academic credit for it! The course will be taught next in January 2015. Click here to learn more and register.

NSF EEID proposal on the effects of landscape structure and management interventions on mountain lion disease dynamics funded!!!

We’re thrilled to announce that our collaborative NSF EEID (Ecology and Evolution of Infectious Diseases) proposal to investigate the effects of landscape structure and management interventions on mountain lion disease dynamics was funded! Our research team includes Sue VandeWoude (CSU Microbiology, Immunology, and Pathology), Kevin Crooks (CSU Fish, Wildlife, and Conservation Biology), Meggan Craft (University of Minnesota), Scott Carver (University of Tasmania), and Chris Funk (CSU Biology). The research will trace the spread of two apathogenic, contact-dependent retroviral agents in geographically distinct puma populations under three different management regimes: (1) supplementation and recovery of the highly endangered Florida panther, (2) large-scale manipulative harvest experiments of a rural Colorado puma population, and (3) steady-state management of puma populations in the Colorado Front Range and Southern California. In addition, the research will inform the disease dynamics of pathogenic diseases from models developed using apathogenic diseases.

NSF RAPID proposal to test the effects of the epic September 2013 floods on stream biodiversity funded!

Drunella_doddsi_2Drunella doddsi, a Colorado Front Range mayfly species, one of many species that may have been affected by the September 2013 floods in the Colorado Front Range. Our collaborative proposal between CSU (PIs: LeRoy Poff, W. Chris Funk, and Boris Kondratieff) and Cornell University (PI: Alex Flecker) to test the effects of the epic September 2013 floods in the Colorado Front Range on stream insect biodiversity was funded by NSF! This extreme flood event, which was widely reported by the national media for its adverse economic impacts and loss of human life, occurred outside the range of historical variation in terms of disturbance magnitude and timing. Importantly, such events are predicted to increase in frequency with climate change. As part of our current NSF-funded EvoTRAC project, we have already collected extensive data on stream insect diversity, genomic variation, community composition, and ecosystem function in the summers of 2011-2013. Because of these pre-flood data, we are in an excellent position to directly test the effects of variation in the magnitude of flooding on stream biodiversity, from the genomic to ecosystem levels. Now, thanks to the NSF RAPID program, we can take advantage of this opportunity by re-sampling our study sites this summer and then comparing genomic variation, community composition, and ecosystem function pre- vs post-flooding to test the flood’s effects. You can read more about this project in Today@CSU.
BT Black Canyon 2411m_smExample of the dramatic changes in stream structure caused by the historic September 2013 floods in the Colorado Front Range. At Black Canyon, shown here, the water level rose approximately 5 m and all riparian vegetation, except for the largest trees, were blown out. Note the house upstream which has been washed into the stream by the floods. EvoTRAC sites in relation to Front Range precipMap showing the distribution of rainfall during the September 2013 floods relative to our EvoTRAC focal sites. Since the rains fell directly on top of our sites, we are in an excellent position to test the effects of the flood on stream biodiversity by re-sampling these sites post-flood.
