EXPERIMENTS underway to explore the spatial dynamics of grazing

Postdoc Carl Cloyed has been working overtime on a cool set of experiments to explore how the spatial distribution and density of resources (biofilm) affect the foraging behavior of a grazing predator (Radix snail). 

"blueprint of freshwater life" initiative

Tony attended a workshop for the "Blueprint of Freshwater Life" initiative, held at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Berlin, Germany. A great initiative - and nice to meet so many new faces with such diverse backgrounds and expertise - excited to be involved!

dragonfly foraging experiment underway

Ashley Olsen ran an experiment in the tracking chamber to explore how the density of prey (mosquito larvae)  and the density of predators (dragonfly nymphs) affect consumption rates. Using the tracking system enables us to explore the behavioral drivers of trophic interaction strength. 

field trip to explore the role of competition in biodiversity

The lab (Tony, Carl, Ash) just returned from an awesome three weeks with John Delong at University of Nebraska's Cedar Point Biological Station in western Nebraska. Our work here centers on exploring the biological mechanisms underlying co-existance in a diverse grassland spider community, which we expect might have some behavioral underpinnings. 

OneSTL Sustainability Summit


Tony attended the biodiversity working group at the OneSTL Sustainability Summit. The Summit brought organizations, governments, and people together to share and learn new ideas for charting a defined path towards a sustainable and equitable St. Louis region. 

lab trip to Tyson Research Center

A short field trip today to Washington University's Tyson Research Center, where we are working with postdoc Solny Adalsteinsson to explore the effects of fire on tick (and thus disease) ecology. 

salamander foraging experiments underway

Postdoc Dave Daversa and summer intern Elizabeth Green have been hard at work getting their salamander foraging experiments underway. Using our unique 12-camera tracking system, the plan is to explore how spatial and temporal variation in the foraging and escape behavior scale up to affect the outcome of species interactions. We are using spotted salamander (Ambystoma maculatum) larvae feeding on gray tree frog (Hyla versicolor) tadpole prey.

And some photos of the experiment...

two internships available in my lab

We currently have two paid undergraduate internships available in the lab for summer 2016. 

1) Using UAV’s to monitor bison movement and vegetation dynamics at the Dunn Ranch Prairie

2) Burning question: How does prescribed fire affect tick behavior in riparian and upland forests

While I encourage interested students to email me with questions about the projects, note that to be considered for the positions students must submit all application materials electronically with the online application form (listing one of these two projects as their preferred option) by the Jan 18th deadline at www.ngrrec.org/internship
