Dissertation Research: Eco-Evolutionary Effects Of An Aquatic Consumer: Linking Phenotypic Diversity To Community And Ecosystem Responses, Kevin S. Simon, Quenton Tuckett, Michael T. Kinnison
University of Maine Office of Research Administration: Grant Reports
This research addresses the interaction between ecological and evolutionary processes by examining the recent evolution of a common invasive fish species, the white perch, in lakes and the consequences of this evolution for community and ecosystem dynamics. White perch have successfully invaded lakes spanning a productivity gradient, which provides diverse selective pressures that may result in altered fish morphology, physiology and ecological role. Adaptation by these fish may, in turn, feed back to affect lake productivity and community structure through several ecological and chemical pathways. This project tests the hypothesis that this rapid evolutionary divergence within a single species has …
Cmg Collaborative Research: Interactions Of Phytoplankton With Dissipative Vortices, Peter A. Jumars, Lee Karp-Boss
Cmg Collaborative Research: Interactions Of Phytoplankton With Dissipative Vortices, Peter A. Jumars, Lee Karp-Boss
University of Maine Office of Research Administration: Grant Reports
The aim of this project is to develop coordinated laboratory experiments and computational models to address a fundamental question in oceanography concerning magnitudes and mechanisms of turbulence effects on phytoplankton and other particles at the spatial scale of individual organisms. The importance of external energy in the form of turbulence in determining relative success of different kinds of phytoplankton dates to the seminal analysis of Munk and Riley (1952) and Margalef (1978). Margalef's "mandala" asserts that high nutrient concentrations and turbulence intensities favor dominance by diatoms, whereas low values favor non-red-tide dinoflagellates. Subsequent work has revealed a wide spectrum of …
Rapid: Assessing Tsunami Impacts On The Benthic Community Of Robinson Crusoe Island, Richard Wahle, Peter Petraitis
Rapid: Assessing Tsunami Impacts On The Benthic Community Of Robinson Crusoe Island, Richard Wahle, Peter Petraitis
University of Maine Office of Research Administration: Grant Reports
This RAPID project will assess the subtidal ecological impacts of the tsunami that struck Robinson Crusoe Island on 27 February 2010 with support from the Biological Oceanography Program and the Office of International Science and Engineering/Americas. It will take advantage of baseline data collected as part of an ongoing Chilean research project. Robinson Crusoe Island belongs to the Juan Fernandez archipelago, some 600 km west of the coast of Chile in the southeast Pacific. The island group is unique for its high level of marine and terrestrial endemism, including a fishery for the prized Robinson Crusoe Island lobster, Jasus frontalis. …
