The quality of the pit greatly affects the foraging success. Antlions face the trade-off between a high quality pit and reserving energy stores. In this study we examined the effects of feeding frequency, substrate size, temperature and location on pit size. Antlions and sand were collected from Pine Point on Douglas Lake and from Sturgeon Bay. We found that antlions will abandon pits to better capture success if not sufficiently fed. In Sturgeon Bay antlions build larger pits than Douglas Lake antlions. There was no effect of substrate or angle of repose leading us to think the difference is due to higher temperatures in Sturgeon Bay. <br/> <br/>Description: Behavioral Ecology Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2027.42/57730 Title: The effect of habitat on constitutive levels and inducibility of leaf phenolics in American Beech (Fagus grandifolia) <br/> <br/>Authors: Zrust, Amanda; Cardone, Frank; Yee, Caroline; Patel, Nikita <br/> <br/>Abstract: Plants use chemical defenses to ward off herbivory. Phenolics, a carbon-based chemical defense, are present in all woody plants. There are many biotic and abiotic factors that can affect the levels of phenolics present in plant tissue. Two factors that can affect phenolic levels are carbon and nitrogen availability. Often these factors vary with habitats. Glacial moraines often have mesic, nitrogen rich soil. Glacial outwash plains often have xeric soil with less nitrogen. To see the effects of carbon and nitrogen availability on constitutive levels and inducibility of phenolics, we tested constitutive levels and inducibility of phenolics in American Beech (Fagus grandifolia) in both habitats. Trees from the outwash plain had higher constitutive levels of phenolics. Though both sites induced phenolics in response to leaf damage, neither site produced a significantly greater amount. <br/> <br/>Description: General Ecology Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2027.42/57729 Title: A terrestrial brook trout <br/> <br/>Authors: Trout, S. B. <br/> <br/>Abstract: Spoiled. That is what my dad’s nickname for me is. Actually, it’s Pourri, French for rotted. My dad, Karl, is full of these verbal mannerisms, Karlisms, derived from who-knows-what obscure anecdotes and movie references. I was a daddy’s girl from the moment I was born. His third daughter, I imagine he was hoping for a boy. Instead he got me and, knowing there would be no chance for a son, made do with a female mini-me. My first name, Stefanie, is taken from his middle name, Steven. My middle name, Brook, qualifies his favorite fish in conjunction with my last name, Trout. My driver’s license elicits numerous comments and questions whenever strangers take note of my incredibly unique name. “Your parents sure must have a great sense of humor!” Often they would call someone else over to see the spectacle of my printed name. At this point I force a polite chuckle while inwardly groaning. Even more frequently I get, “Is your dad a fisherman?” <br/> <br/>Description: Environmental Writing and Great Lakes Literature Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2027.42/57728 Title: Who will I talk to when you're gone? <br/> <br/>Authors: Vander Naald, Breanne <br/> <br/>Abstract: Two days before I came to the Biostation, my dad, Phil Vander Naald, was diagnosed with non-small cell lung cancer. There is a one percent chance that he will be around for my twenty-sixth birthday. That my dad will not be there to see me get married and have children is a thought that robs me of my breath every time it enters my head. Even when we had an argument, there was still the expectation that we would have another 30 to 40 years to spend together. Not talking for a few months was not viewed in the same way as it is today: when every month is precious and many things simply aren’t important enough to worry about much less argue over. The saddest irony of it all is that I started smoking cigarettes again when I heard about Dad’s cancer and all three of my other siblings smoke to some degree and my dad is dying of a cancer usually cause by smoking. <br/> <br/>Description: Environmental Writing and Great Lakes Literature Sun, 29 Oct 2006 22:58:59 GMT
