By Katherine Dami, Jennifer Ferlenda, Annarose Quinn Introduction • M. uniflora grows in moist or hardwood (Kong, 2015). • Evolved from an autotrophic ancestor (Hirce, 1972). • Do not have (Lutz, 1973). • ~4,000 known parasitic (Press, 2005) • Associates with fungal species in the family (Massicotte, 2004). • Spend their life underground without light, except for its flowering period when they develop shoots (Tsukaya, 1998). .

Our Interest

Most studies focused on phylogeny…

...we wanted to do something different

(Kong, 2015) Hypothesis 1

H1: As canopy cover increases, Monotropa uniflora will grow in larger clusters.

H0: Canopy cover has no effect on the growth pattern of Monotropa uniflora.

Hypothesis 2

H1: As soil moisture increases, Monotropa uniflora will grow in larger clusters.

H0: Soil moisture has no effect on the growth pattern of Monotropa uniflora. Hypothesis 3

H1: As pH decreases, Monotropa uniflora will grow in larger clusters.

H0: Soil pH has no effect on the growth pattern of Monotropa uniflora. Experimental Design

• Ecological Theory • Does it support what is known? • Why did we get these results? • Self critique • Follow up studies Conclusion

• Canopy cover percentage • Soil moisture percentage • Soil pH • Soil temperature • Leaf litter thickness Fun Facts! References
