Comparing Resource Allocation Of Fruiting Native And Invasive Species, Rheanna Meier, Suann Yang Apr 2019

Comparing Resource Allocation Of Fruiting Native And Invasive Species, Rheanna Meier, Suann Yang

Papers, Posters, and Recordings

The ability of invasive plant species to rapidly overtake native flora has become a growing problem in the Northeast US and elsewhere. A variety of mechanisms contribute to this ability, such as different strategies of resource allocation to fruit and flowers in native compared to invasive species. Life history theory suggests that fruit and flower size should be inversely related, since the plant has a finite number of resources. We hypothesize that there is a ratio of fruit to flower size that allow invasive species to quickly outcompete native species—a larger flower would allow for better pollination, but a ...


Density Of Hemigrapsus Sanguineus And Carcinus Maenas In Kettle Cove, Cape Elizabeth, Maine, Valerie Huston, Teresa Martel, Zimzim Mohamed Apr 2019

Density Of Hemigrapsus Sanguineus And Carcinus Maenas In Kettle Cove, Cape Elizabeth, Maine, Valerie Huston, Teresa Martel, Zimzim Mohamed

Thinking Matters Symposium

Our focus for this project is to determine how the population densities of Hemigrapsus sanguineus, Asian shore crab and Carcinus maenas, European green crabs have shifted over a brief period of time. We are comparing data collected on September 17, 2018, to data collected on October 22, 2018. The location where the two sets of data were collected from is Kettle Cove, Cape Elizabeth, Maine. The GPS coordinance was 43°.33.55N70°.13.40N. We discuss what affects the influences of environmental factors such as temperature, salinity, high intertidal versus low intertidal, and percent ascophyllum cover affect have on the ...

In this teaching module, students will explore emerald ash borer (EAB), its impacts on the ash trees, and how warming temperatures could affect EAB populations. The emerald ash borer is a green buprestid or jewel beetle native to north-eastern Asia that causes devastating disease in ash trees.
