Many species of Dinoflagellates are capable of producing bioluminescence. Most species will have an optimal temperature range for bioluminescence production. With sea surface temperatures expected to rise, we have designed an experiment to test the relationship between temperature and bioluminescence in Pyrocystis fusiformis.
Bacterial Metabolism Of Glucosinolates From Brassica: Association With Isothiocyanate Production, Stephanie Thomas, Jiaxuan Li, Michael J. Miller
Bacterial Metabolism Of Glucosinolates From Brassica: Association With Isothiocyanate Production, Stephanie Thomas, Jiaxuan Li, Michael J. Miller

Study Focus: To explore the alternative metabolic pathways of GSLs in bacteria, present on the surface of brassica vegetables.
Hypothesis: The alternative pathways used to metabolize GSLs in bacteria located on the surface of brassica vegetables, may contribute to the high variance of human gut GSL conversion to ITC.
Concentrating On Carbon Concentration In Algae, Chandra Davies, Steven Burgess
Concentrating On Carbon Concentration In Algae, Chandra Davies, Steven Burgess
PRECS student projects
Carbon Concentrating Mechanisms Improve Photosynthesis Rates in Low-Carbon Environments. CCMs allow the aggregation of carbon near the site of rubisco, that way even small amounts of available carbon are being utilized.
Yes, this is important to you!
Albeit somewhat indirectly, but massively nonetheless! Algae are a driving force behind the global carbon cycle, they sequester CO2 in the oceans. Understanding the mechanisms behind the tiny marine alga O. tauri gives us a better understanding of a vital global process.
Polinators In Peril - Are Illinois Native Bees Getting Smaller?, Anthony Lamb, Tristan Barley, Adam Dolezal
Polinators In Peril - Are Illinois Native Bees Getting Smaller?, Anthony Lamb, Tristan Barley, Adam Dolezal

Why it matters.
Pollination services provided by native bees are an important natural process, providing ~150 billion dollars globally in agricultural gains.
A bee’s body size is a trait that is an important indicator of the nutritional environment. A loss of habitat results in a loss of rich nutritional environments as flowers and resource become more fragmented and scarcer.
It has been discovered that a bee’s body size is a determinant of their foraging range. The smaller the bee, the less distance they can travel for food, therefor, the more susceptible they are to habitat loss and resource limitation.

Amaranthus is a genus containing species that are highly desirable, yet underutilized crops and species that are highly despised pernicious agricultural weeds.
- Cultivated species are primarily grown as nutritious pseudograins, colorful ornamentals, or leafy greens and are recognized for tolerance to heat, drought, and salinity.
- Weedy amaranths possess similar adaptive traits, in addition to evolved resistance to numerous herbicides, and pose severe challenges to global agriculture.
- Plant pigments (i.e., betalains, carotenoids) are central to understanding this impressive diversity of phenotypes and adaptive traits.

Flowers emit volatiles to attract pollinators, but these volatiles can also attract pest insects. Our study builds on earlier findings that showed that cucumber beetle attraction to squash flowers is mediated by volatile release and cucurbitacin accumulation (Theis, 2014, DOI: 10.3732/ajb.1400171). Of the three main domesticated squash species, only a few varieties of Cucurbita maxima had large quantities of floral volatiles and cucurbitacin (Andersen and Metcalf, 1987, doi: 10.1007/BF01020152); however, these studies were limited in the number of varieties that were examined. Here, we increased the number of C. maxima varieties examined, to identify patterns in floral volatile production, with …

Social behavior is diverse. For example, males from two stickleback ecotypes (whites and commons, Fig. 1) are highly divergent in courtship and parental care behavior [1]. Little is known about ecotypic differences in female behavior. In this study, we develop methods to quantify female preference in this system.
Intra- And Interspecific Variation In Tadpole Lateral Line Cells, Sarah Porth, Lisa Surber, Eva Fischer
Intra- And Interspecific Variation In Tadpole Lateral Line Cells, Sarah Porth, Lisa Surber, Eva Fischer
PRECS student projects
Background
- The lateral line is a sensory system that detects motion and pressure in fish & larval amphibians.
- The sensory end organs are called neuromasts.
- A gosner stage describes the 46 stages of tadpole development
Hypothesis: We hypothesize that the number of neuromasts will vary more between species than within a species.

Why is understanding stress response in maize so important?
- Maize, along with rice and wheat, provide at least 30% of calories to over 4.5 billion people
- Increases in flooding events has heavily impacted natural vegetation and crop production
- Combinatorial stresses, particularly flooding and herbivory, remain understudied for both modern and ancient verities of maize
- Ancient maize may be a superior genetic resource for flood-tolerant corn
