McKinnon et al. She is now professor of biology at York University and is affiliated with more than a dozen organizations that seek to preserve bird habitats. ecology and conservation. how landscape cover and rainfall influences intra-tropical migration and teamed up with researchers, biologists, and volunteers across North Research in the lab ranges from natural history and taxonomy to molecular phylogenetics and biogeography. I frequently teach the Biology Field Course BIOL 3001 (commonly in Algonquin Park, but also in Belize), and I have taught a diversity of other 3rd-year and 4th-year courses in Biology and 1st-year courses in NATS. Our research interest concerns the basic regulatory mechanisms involved in cellular differentiation. Stutchbury lab does research on the conservation biology and ecology of cbucking@yorku.ca. and stopover sites, and hence potential threats. migratory songbirds in. Fall pace and Gulf of Mexico.pdf, Fraser et al. Graduate studies in Biology at York U are firmly based on cutting-edge research. 2015 However, it also informs character animation as well as automatic face and gesture recognition, and it has implications for applications of virtual reality for telecommunication, entertainment, training and therapeutic intervention. Research Areas: Molecular Biology, Biochemistry, Systems Biology, Metabolic Engineering. Nicom Digital® birds) that allow us to test many questions about migration Historical data and experimental manipulation of landscape settings allows us to determine the habitat requirements and status of wild bee species to make sustainable land use and conservation recommendations. Fogo Island Caribou Ecology … One simple question is: what produces the force that causes the chromosome to move poleward? The ability of adiponectin and lipocalin-2 to mediate direct effects on the heart may help explain the strong association between obesity and cardiovascular complications, including heart failure. The Faculty of Science at York University is located in Toronto, Canada, and is a hub of research and teaching excellence. 2013. To answer this, my research focuses on two reciprocal questions: My research is based on three key biological fields: physiology, behavior, and evolution with an emphasis on physiology. We try to understand the entire process of cell division, but concentrate on chromosome movements during  anaphase. Faculty Profile It is well known that various intracellular signalling pathways potently regulate cell differentiation by targeting nuclear transcription factors. During anaphase, chromosomes move slowly to a spindle pole at a speed near that of a tectonic plate. 2006 sharma11@yorku.ca. Human-induced ecological stressors, such as global climate change, pollution, introduction of non-indigenous species, and alterations in land use, water quality and habitat, are impacting our native ecosystems. for both Wood Thrushes (>100 birds) and Purple Martins (>250 Members of this conserved family of RNA chaperones have critical functions in cellular growth. Cytoskeleton 70: 241-259. In addition, results of our research can be used to predict changes in the mosquito and midge species composition by increased environmental salinity from the continued use of road salt. Since the 1980s, she has followed songbirds to their wintering grounds in Latin America and back to their breeding grounds in North America to understand […] The long-term goal of my research is to bridge from biomedical research addressing fundamental neurobiological questions to clinical applications and to inform the translation of important discoveries from molecules to bedside. Stutchbury lab does research on the conservation biology and ecology of cpeng@yorku.ca. We are currently dissecting the effects of kinase mediated phosphorylation of MEF2 protein in order to fully understand how it serves as a nuclear sensor of growth factor -activated signalling pathways. building in need of mitigation. John Tautin, The Purple Martin Conservation Association . a montage from the Graduate Program in Biology . The laboratory uses a combination of molecular and physiological techniques including PCR, qPCR, Western blotting to identify tissue-level expression of genes, intracellular microelectrodes and ion-selective microelectrodes to measure membrane potentials and ion composition in biological fluids and Scanning Ion-selective Electrode Technique (SIET) to measure real-time movement of ions across transporting epithelia. 92: 175-186. Bridget STUTCHBURY, Professor of York University, Toronto | Read 119 publications | Contact Bridget STUTCHBURY songbirds to their wintering grounds and back. We are currently studying the role played by adiponectin in glucose uptake and metabolism in skeletal muscle and investigating the signaling mechanisms responsible for effects of these adipokines. The information gained from this research can provide fundamental insights for development of lead compounds useful for control or eradication of these disease vectors. Identifying tissue targets regulated by hormonal factors, which involves determining receptor expression profiles, allows the subsequent application of tissue-specific bioassays (muscle contraction assay, epithelial transport assay, etc.) We use genomics to uncover the genetic basis of group formation and transcriptomics to understand the epigenetic modifications involved with social experience. Purple Martin Migratory Connectivity.pdf, Habitat Quality and Juvenile I am constantly looking for interested graduate students from various backgrounds, including Biology, Psychology, Engineering and Computer Science. (416) 736-2100. We aim to understand both the basic mechanisms by which these proteins enhance the correct folding of target RNAs as well as how aberrant La and La-related protein function contribute to human disease states. Bridget Stutchbury has a chest freezer stuffed with songbirds, a makeshift morgue that troubles her heart. View Bridget Stutchbury’s profile on LinkedIn, the world's largest professional community. Understanding the Below – Listen to Dr. Paluzzi speak about his research! We don’t really know yet what tethers do, but initial experiments indicate that tethers signal between separating chromosomes to regulate their velocities of motion (Sheykhani e al., 2017). Subsequent work explored the mechanisms by which these factors regulate cellular gene expression and differentiation. This fundamental knowledge can permit the development of novel and specific agents to affect control on mosquito and midge populations. Carry over effects. conducting a study of window-collision mortality on the York U campus to In Which hormones control reproductive behavior and related physiological processes? Fabian et al. These anthropogenic stressors include recent climate change, acid rain, contaminant pollution, nutrient enrichment (eutrophication), land-use change (vegetation clearance for agriculture, urbanization etc), reservoir/impoundment construction and exotic species invasions, to name a few. Most concentrate on microtubules, but other components in spindle fibres include actin and myosin; no-one knows what the different components do. Using macrophotography and microscope imaging, we are able to capture the distinct morphologies and showcase the beauty of wild bees.
