Dayvis collecting pollen

Dayvis collecting pollen from an Echinacea head

The main research project is to determine evolutionary and ecological consequences of habitat fragmentation on purple coneflower, a beautiful and relatively common prairie flower. The research site is in western Minnesota. Stuart Wagenius is the field supervisor.

The narrow-leaved purple coneflower, Echinacea angustifolia, grows in the former tallgrass prairie and plains of North America, a habitat now fragmented by human activities such as agriculture, development, and roads. Echinacea now exists in isolated populations of various sizes. We know that seed production in isolated plants is limited by pollination and that genetic diversity is lower in small populations compared to large populations. We still don’t know the long-term consequences of reduced seed set, low-fitness seedlings, and reduced genetic diversity on the persistence of these populations.

During this summer, we will systematically map about 2000 plants in natural populations that have been observed annually since 1996 to compare the fecundity and mortality of plants in small and large populations. For another ongoing project, we will measure growth, flowering, and fitness traits of plants growing in research plots. The goal of this project is to estimate the genetic and environmental influences on Echinacea plants originating from small and large remnant populations. In addition to measuring plants and collecting data, we will maintain plots by mowing and weeding.

You will gain skills in identifying plants, surveying natural plant populations, measuring plant traits in experimental plots, hand-pollinating plants, and observing & collecting insects. You will learn many techniques for experimental field work in plant ecology, genetics, and plant-insect interactions. Specific skills you may gain include collecting seed, surveying and GPS techniques, artificially pollinating flowers, identifying insects, mapping plants, and characterizing communities. You will also gain appreciation for long-term experiments and work as part of a team.

Team Echinacea 2013

The study area is a rural agricultural community. The closest towns are Kensington (56343) and Hoffman (56339), MN. Alexandria, a larger town with a movie theater, is 20 miles away. In Solem township there are dirt roads, a highway, railroad tracks, wetlands, and lots of corn and soybeans. There are prairie remnants scattered throughout the township. You’ll live in a house with basic amenities and a basketball hoop. You’ll share the common area and cook with other team members, but you’ll have your own space and a bed. Usually we’ll eat lunch together at our base station. Interested in applying to one of our positions? Check out our current opportunities. Thanks for reading all the way to the end of this page.
