In a previous post, I wrote about my journey into learning (and continuing to learn) Bayesian statistics. Making the jump into Bayes would have been impossible without some great resources (books, articles, packages, and blogs) that have come out in the last few years. Here’s my quick review of books … Continue Reading Three books that helped me learn Bayesian statistics
When I was in grad school, Ken Burnham gave a seminar in my department about model selection and met with our research group. His book with David Anderson had been out for ~3 years at the time (it now has more than 45,000 citations!), but I had zero idea of … Continue Reading My statistical journey as an ecologist
University of South Dakota: The Wesner Lab is recruiting aquatic ecology graduate students to begin in May 2019 (2 positions), or spring 2020 (1 position) in the Department of Biology at USD. Students can apply for either the MS or PhD programs. Details of support for each project differ somewhat, … Continue Reading Grad positions – aquatic ecology

Both of the food webs above contain the same number of species. Which one best describes how fish interact in nature? The graphs on the right also contain the same number of species and same prey, but have very different depictions of how fish…
I wrote this for my students last year. They are thoughts I have to constantly remind myself of in my own writing. They are far from universal. I hope they help. Jeff Wesner (21 August 2017) Readers and reviewers are desperate to learn new and exciting science. They are not … Continue Reading How to write a research article in ecology
Abraham joined our lab in August. He was an awesome undergrad at USD and brings a bunch of experience working in applied science from USGS. We’re lucky to have him join our team!
Wolbachia is a fascinating critter. It’s a bacterial genus that infects lots of arthropods, and does all kinds of things to them that make great headlines, like killing males or making them eat brains. However, it’s commonness is disputed, particularly among insects that live in rivers and lakes (i.e. freshwater insects). … Continue Reading Eric Sazama’s first article is published! Wolbachia in aquatic insects.
Jake Kerby (PI) and Jeff Wesner (Co-PI) received a State Wildlife Grant to study the effects of tile drains on prairie pothole wetlands. This comprehensive study will measure chemical contaminant levels in 18 wetlands (e.g. Se, Neonicotinoids, Nutrients) and their effects on amphibians, insects, and fish.
Congratulations to Brianna Henry! Brianna is an undergraduate at Clarion University of Pennsylvania who was just awarded an NSF GRFP fellowship to conduct research on herbicides and wetland ecosystem ecology. This award is highly competitive – only 12% of the 16,500 submitted proposals were funded. She will join our lab … Continue Reading Brianna Henry is an NSF Graduate Research Fellow!
Eric joined the lab in Fall 2014 to pursue his M.S. He’s developing a fascinating project that will ask how Wolbachia, a widespread endosymbiotic bacterium, is distributed within aquatic insects. He will then ask how infection by Wolbachia might alter the ability for insects to complete metamorphosis, a key process in linking … Continue Reading Welcome to Eric Sazama!
Wesner JS, Meyers P, Billman EJ, Belk MC. Habitat selection and consumption across a landscape of multiple predators. Ecology and Evolution. We tested whether egg-laying female insects could detect differences in predator community composition. Because some predators are more lethal than others, the ability to differentiate predator risk when laying … Continue Reading Habitat selection paper published in Ecology and Evolution
Kraus, JM, DM Walters, JS Wesner, CA Stricker, TS Schmidt, and RE Zuellig. In press. Metamorphosis alters contaminant transfer and diet tracers in insects. Environmental Science and Technology (open access) We’re on a roll with metamorphosis at ES&T. Johanna Kraus, a Mendenhall Fellow at the USGS, led the way on this very important … Continue Reading Second metamorphosis paper accepted to ES&T! UPDATED
Wesner, JS, JM Kraus, TS Schmidt, DM Watlers and WH Clements. Accepted. Metamorphosis enhances the effects of metal exposure on the mayfly, Centroptilum triangulifer. Environmental Science & Technology This paper shows that metal concentrations that are non-lethal for mayfly larvae can become lethal when those larvae undergo metamorphosis to become winged adults. … Continue Reading Metamorphosis paper 1 accepted to ES&T
