HOx radical chemistry in forest environments:  Measurements and characterization of instrument interferences
Philip Stevens (IU Dept of Chemistry)

This summer the Griffy Woods Field Station was utilized in a joint project with researchers from Indiana University, Mines Douai,and University Of Massachusetts Amherst to better understand forest chemistry and the instruments utilized to measure chemical interactions within a forest setting. Philip Stevens, the principle investigator, believes that finding a standardized and unified method of measurement of these atmospheric chemicals will greatly help in the understanding of the interactions that relate to climate change and air quality.

Predator spreaders: an experimental test of hypotheses linking predation to disease spread
Spencer Hall (IU Dept of Biology)

The Hall Lab is studying the influence of infectious disease on population dynamics and community interactions. Their work focuses on the determinants of spatial and temporal dynamics of bacterial and fungal epidemics in Daphnia. This work relies on combination of community ecology, physical limnology, and epidemiological modeling.

Hormonal mechanisms of aggressive behavior in birds
Kimberly Rosvall(IU Dept of Biology)

This research is a part of a larger project aimed at understanding inter-specific variation in hormonal mechanisms of aggression. In some species, aggression is mediated by the steroid hormone testosterone, but in other species it is not. Our research aims to understand the proximate and ultimate factors shaping this inter-specific variation in mechanism. The subject of this research is the song sparrow, a ubiquitous ‘backyard’ bird, known for its beautiful and complex song. Song sparrows fare quite well in suburban areas, as their natural habitat is typically the ‘edge’ between grassland and woodland, which is mimicked in the yards, parks, and trails surrounding Bloomington. Song sparrows are an important part of this broad project, because they seasonally shift their use of testosterone-dependent and testosterone-independent mechanisms of aggression.

Evaluating the effects of biochar soil amendments on prairie plant and arbuscular mycorrhizal fungal (AMF) communities
Geoffrey House(IU Dept of Biology)

This research measures the interactive effects of adding biochar to the soil of prairie restorations in combination with including different communities of arbuscular mycorrhizal fungi (AMF) plant mutualists in the soil.  Biochar can help increase plant growth while simultaneously sequestering carbon in the soil for long periods of time, but there are limited studies using biochar in non-agricultural ecosystems.  The effects of different biochar application rates will be quantified for: 1) AMF community composition by using next-generation sequencing, 2) plant community diversity, and 3) soil structure.
