Graduate Fellowships available in Environmental Neuroscience at UPR
Puerto Rico Center for Environmental Neuroscience (PRCEN) Graduate Fellowships
For the 2013-2014 academic year, a total of 8 graduate fellows are available for studying: (1) coral calcification mechanisms; (2) human impacts on estuarine habitats; (3a) the role of epigenetics in neuronal adaptation to environmental stressors; (3b) the consequences of environmental stress on synaptic growth, function and plasticity; and (4) effects of urbanization on aquatic fauna.
Application deadline: 15 March 2013
Corals create reefs by depositing calcium carbonate. Remarkably, little is known about the mechanism of the calcification process. One of the aims of this project is to better understand calcification on a molecular level. Our goals are to identify transporters that move calcium and bicarbonate to the site of calcification, and to understand how they are susceptible to environmental pressures. This will require a highly integrated approach, coupling neurophysiological techniques with ecology and environmental science.
Puerto Rico is one of the most densely populated islands in the world, providing a unique opportunity to study anthropogenic influences on the tropical biosphere on a small spatial scale. This project is part of the new Puerto Rico Center for Environmental Neuroscience (PRCEN) funded by the NSF CREST initiative (Centers of Research Excellence in Science and Engineering program) that combines neuroscience and environmental science to tackle environmental issues in a variety of Puerto Rican ecosystems. Our team includes collaborators from multiple disciplines and institutions across the nation. Interested students should contact the project leader, Dr. Joshua Rosenthal (email@example.com).
Estuaries receive water inflow that is high in nutrients from both marine and freshwater sources, making them among the most productive natural habitats on earth. As nearly 60% of mankind lives in the immediate vicinity of estuaries, they provide an important interface for assessing the impact of human activities on the biosphere. In 1992, the San Juan Bay Estuary (SJBE) was designated an estuary of “national significance” by the Environmental Protection Agency (EPA). The SJBE was the first, and remains the only, tropical estuary system to be included in the EPA’s National Estuary Program (NEP). The studies comprising this subproject focus on a major crustacean inhabitant of the SJBE, the blue crab Callinectes sapidus, as an experimental model for assessing effects of anthropogenic factors on nervous system function. Our team includes collaborators from multiple UPR campuses and from several mainland universities and research institutions. Interested students should contact the project leader, Dr. Mark Miller (firstname.lastname@example.org)
(3) Graduate fellowships in: (a) the role of epigenetics in neuronal adaptation to environmental stressors and (b) the consequences of environmental stress on synaptic growth, function and plasticity.
You will join a multidisciplinary team with expertise in Drosophila genetics, synaptic growth and plasticity, RNA editing, and the terrestrial ecology of Puerto Rico.
Changes in the environment can generate considerable challenges in the nervous system. The long-term goal of this research is to characterize the physiological and molecular consequences of environmental change on the nervous system of wild Drosophila melanogaster. Over the past fifty years,Drosophila melanogaster has been the model of choice to uncover essential processes in developmental biology, cell biology, and neuroscience. We propose to study mechanisms of plasticity that have broad impacts on nervous system function, and by consequence have obvious potential for environmental adaptation. Interested students should contact the project leader Dr. Bruno Marie(email@example.com) for more information.
The River systems' project of the PRCEN will compare the effects of urbanization on Puerto Rican rivers and its aquatic fauna. To do this, we will first analyze three representative rivers in which we will identify and quantify extraneous chemicals. Four animal models, zebrafish, mosquitofish, and two types of prawn, will be exposed to pollutants found in the three rivers followed by monitoring of their fast-start escape response and associated behaviors and assessment of the integrity of the underlying neural networks. The project will accomplish three objectives: 1) assess the levels of heavy metals and storm sewer runoff contaminants on acutely and chronically contaminated urban rivers in comparison with those of undeveloped areas; 2) monitor the effect of these contaminants on the fast-start escape response and associated interactive behaviors in fish and freshwater prawn; and finally 3) determine the effect of the contaminants on survival and integrity of the neural networks involved in those behaviors in fish and freshwater prawn.
Each of the three objectives of this proposal can serve as separate projects for graduate students. Individual types of experiments within these objectives, which can also serve as subprojects for collaborating undergraduates, include collecting water/sediment samples from each river and measuring the levels of various types of contaminants, assessing the escape response before and after exposure to one each contaminant in each fish and prawn species, assessing aggressive behavior before and after exposure to each contaminant in prawn, looking at changes in the neuromast cells of the zebrafish lateral line in response to the contaminants, doing the immunohistochemistry for a transmitter or receptor type or the neural tract tracing in response to exposure to the contaminants in the CNS of each species, etc. Interested students may contact the project leader Dr. Maria Sosa (firstname.lastname@example.org) for more details.
