We would like to thank the University of Miami and Dr. Dana Krempels for supporting our research. Additionally, thank you Winter Beckles for the invaluable guidance he provided throughout the semester.

Introduction

Methods

● Species richness is the number of different species represented in an egological community, but does not take into account relative abundance.

● Species abundance is the relative amount of species in an ecosystem

● In this experiment, our question is does species richness and species abundance differ between Lake Osceola and Matheson Hammock park

● Overall hypothesis: there will be a difference in the richness of species and species abundance between Lake Osceola and Matheson Hammock Park

● Null Hypothesis: the species richness and species abundance will not be significantly different between Lake Osceola and Matheson Hammock Park

● Predictions: There will be a higher species abundance in Lake Osceola because there is less disturbance to the habitat. There will be a higher species richness at Matheson Hammock Park because it is the ocean.

Mann-Whitney U Value: 6.5Critical Value: 5

In this experiment, we are comparing the speciesrichness indices and relative species abundancevalues between Lake Osceola and MathesonHammock park.

● For species richness, the U-value is 6.5. Thecritical value of U at p < .05 is 5. Therefore, theresult is not significant at p < .05

● For species abundance, our U-value is 12.5 and islarger than the critical U-statistic at alpha =0.05,which is 5.Therefore, the result is not significant at p< .05.

We fail to reject both of our null hypothesises.Therefore, there will not be a significant differencebetween the species richness and species abundancebetween Lake Osceola and Matheson Hammock Park.

Acknowledgements

We will collect 3 samples from each locality each week for 2 weeks in a row. In total, we will have 6 samples for each locality and 12 samples in total.

● A field notebook to record the information about your sites and samples

● Pencil and not a pen● Containers (cups with lids) to collect samples● Disposable plastic pipets and straws ● A marker to mark sample, pipets and straws ● pH strips ● One meter colored transect lines

We will select three collection sites that have similar physical features. Each sample collected will be labeled for the cup and lid including locality, transect, #, date and time. In total, we have 24 slides to analyze(2 per sample.)
