Northern leatherside chub paper accepted in Ecology of Freshwater Fish
Last week brought great news that our work on the food webs of northern leatherside chub was accepted to Ecology of Freshwater Fish. This study documents a shift in trophic position of common fishes in streams where NLC is absent. The shift is independent of habitat variation, meaning the food webs … Continue Reading Northern leatherside chub paper accepted in Ecology of Freshwater Fish
We got our first grant!
An internal grant from USD will help to establish “Model systems to understand threats to freshwater ecosystems.” That is – we can now hire several undergraduate students and buy equipment to help build 1) a large outdoor artificial stream system, and 2) an indoor culture of the model mayfly Centroptilum triangulifer.
Welcome to Jerry Warmbold!
Jerry will start his M.S. in the Wesner lab in January 2014. He’s interested in fisheries and fish ecology. His project will answer questions related to the influence of fish species loss on linked aquatic-terrestiral ecosystems.
New paper in Freshwater Science
Wesner, JS. 2013. Fish predation alters benthic, but not emerging, insects across whole pools of an intermittent stream. Freshwater Science 32:438-449 Direct predation on developing insects undoubtedly reduces the number of emergers, right? In this paper, the answer is maybe. We blocked off 10 entire pools of a small stream … Continue Reading New paper in Freshwater Science
New Paper in Ecology
Wesner, JS, EJ Billman, and MC Belk. 2012. Multiple predators indirectly alter community assembly across ecological boundaries. Ecology 93: 1674-1682. (see Publications for a .pdf). Choosing where to lay eggs is critical to an organism’s fitness. Make the wrong choice, and your offspring are toast. It’s no surprise, then, that … Continue Reading New Paper in Ecology
New Paper in Freshwater Biology
Wesner, JS. 2012. Emerging aquatic insects as predators in terrestrial systems across a gradient of stream temperature in North and South America. Freshwater Biology 57: 2465-2474. For most aquatic insects, emergence to adulthood means two things: sex and death. As a result, emergence is often synchronous (sex requires other individuals, … Continue Reading New Paper in Freshwater Biology
