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.

Future Earth and the Global Biodiversity Center land grant for sustainability science



Congratulations to Josh Tewksbury, director of the Colorado Global Hub of Future Earth, and W. Chris Funk, director of the Global Biodiversity Center at Colorado State University’s School of Global Environmental Sustainability, for receiving a $2 million grant from the Gordon and Betty Moore Foundation to fund sustainability science projects. See the full story here.

Congratulations to Sarah Fitzpatrick for landing tenure-track job!!!

Congratulations to Dr. Sarah Fitzpatrick for getting a tenure-track job at Kellogg Biological Station!!! 100% of Funk lab PhD students and postdocs who wanted a career in academia have landed tenure-track jobs (N=5), including Melanie Murphy, Jeanne Robertson, Alex Trillo, and Mónica Páez. Way to go Funklings!!

Congratulations to Maybellene Gamboa for passing her comprehensive exam!

A huge thanks to the Funk Lab Ascaphus crew!

Alisha Shah led the field crew and shared her Zen mastery of thermal tolerance experiments with them.

A huge thanks to the Funk Lab Ascaphus crew for a tremendous effort and successful field season, sampling and conducting physiological experiments on the coolest frog on planet Earth, the tailed frog (Ascaphus truei and A. montanaus). From June to September 2016, they sampled multiple elevational gradients in northern California, the Oregon Cascades, western Montana, and northern British Columbia as part of a project aimed at understanding variation in physiological tolerance and other traits across elevational and latitudinal gradients, the genomic underpinnings of this variation, and implications for conservation of this iconic Pacific Northwest stream species.

The Funk Lab is recruiting a Postdoc, PhD students, and Undergrads!

The Funk Lab is recruiting highly motivated people with interests at the intersection of conservation genomics, evolutionary ecology, and natural history. Positions are available at the Postdoctoral, PhD, and Undergrad levels. See “Joining the Lab” and Postdoc ad for details.

Double congrats to DRA. Mónica Páez-Vacas!

Dr. Professor Mónica Páez-Vacas

A huge congratulations to Dr. Mónica Páez-Vacas for successfully defending her PhD on adaptive divergence and landscape genetics of the poison frog Epipedobates anthonyi in July. One week later, she found out she got a job as a Professor at the Universidad Tecnológica Indoamérica in her hometown of Quito, Ecuador. That’s called a good week!

The Funk Lab welcomes Rebecca Cheek to the lab!

The Funk Lab welcomes its newest PhD student–Rebecca Cheek–to the lab. Rebecca hails from Fairbanks, Alaska, where she grew up and completed her bachelor’s degree at the University of Alaska. She will be working on the genomics, evolutionary ecology, and conservation of the fascinating Island Scrub-Jay system for her dissertation work.

Manuscript on comparative biogeography of mayflies (Ephemeroptera) accepted for publication in Proceedings of the Royal Society B: Biological Sciences and photo of the Oyacachi River selected as journal cover

Proceedings of the Royal Society London B: Biological Sciences recently accepted a paper by Brian Gill and other EVOTRAC coauthors and will feature part of their Ecuadorian study area as their journal cover. In support of the ‘Mountain Passes are Higher in the Tropics’ hypothesis, the research team found higher species richness, higher cryptic diversity, and smaller elevational ranges of mayflies in the Ecuadorian Andes than in the Colorado Rocky Mountains. These differences were not detected using morphology alone, but rather only after integrating morphology and DNA barcoding, underscoring the importance of addressing cryptic diversity in large-scale biogeographic studies. These results support climate variability as an important driver of global trends in species diversity and distributions and add to the growing literature supporting higher tropical than temperate species vulnerability to global warming.

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

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.

Funk lab undergrad–Jill Gerberich–awarded an NSF Graduate Research Fellowship!

Congratulations to Jill Gerberich for being awarded an NSF Graduate Research Fellowship!!! This is a very prestigious fellowship awarded to promising students to pursue a PhD. Jill has been an undergraduate researcher in the Funk lab for four years helping former PhD student Sarah Fitzpatrick (now a postdoc at Michigan State University) and current MS student John Kronenberger with research on the effects of gene flow on adaptation, fitness, and population dynamics in Trinidadian guppies and current postdoc Patricia Salerno with research on the effects of an historic flood on genetic variation in stream insects. Jill has also conducted independent research on dispersal patterns and fitness consequences in Trinidadian guppies. Jill’s hard work and dedication to a career in ecology and evolution has paid off. Contact Jill if you need an awesome PhD student in your lab! She plans on starting graduate school in the Fall of 2017.
