It is possible to obtain this long-term data through proxy methods, such as through examination of paleoecological data archived in lake and pond sediments. 2010 Breeding/molt carry over effect.pdf. the extent of individual flexibility in timing and routes. Much of our work centers around the the La and La-related proteins. View Bridget Stutchbury’s profile on LinkedIn, the world's largest professional community. Perception means to turn measurements obtained from sensors such as eyes and ears into the coherent, predictable, and more or less reliable experience that we call “reality”. We study solitary and weakly social bees to understand the genetic underpinnings and ecological constraints selecting for social behaviour. We utilize both freshwater and brackish water dwelling species to understand the mechanisms that have evolved in response to these two distinct habitats. In Communication between cells in the nervous system is mediated by chemical and electrical synapses. Neuroendocrine systems are investigated at the molecular, cellular and tissue level in order to determine their importance and contribution to the biology of whole organism. Chromosomes moved normally after the UV severed both microtubules and actin (Forer et al., 2003; Sheykhani et al., 2013a), so we argue that chromosomes move because a spindle matrix propels the chromosome’s spindle fibre poleward (review in Johansen et al., 2011; Forer et al., 2015). Although I am in the Teaching Stream, I continue to study bird migration. Therefore, our aim is to delineate the growth factor-activated signalling pathways that specifically converge on and modulate key transcriptional regulators such as MEF2 proteins during myogenesis. Dr. Bridget J. Stutchbury Department of Biology, Faculty of Science Distinguished Research Professor. 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. These agents can be targeted at the level of the molecular ion transport machinery or at the neural and hormonal level. Sediments are natural archives of ecological data, with a host of physical, chemical, and biological variables providing insights into past aquatic ecosystem conditions. Included in this post translational analysis of MEF2 function is the identification of MEF2 interacting proteins using state of the art tools in Mass Spectrometry. Electrical synapses, the gap junctions of the nervous system are far less understood than chemical synapses, but accruing evidence demonstrates that throughout the CNS, gap junction–mediated electrical signals synchronize neural activity on millisecond timescales via cooperative interactions with chemical synapses. Bridget Stutchbury uses geolocators to discover when and where the birds go and the route they travel. study the impacts sub-lethal effects of pesticides on songbird migration. Moreover, muscle differentiation is extremely sensitive to the action of various growth factors. Even less is know about their fate after I am interested in circadian rhythms, the daily activity cycles driven by internal clocks in almost all organisms, and I work with the fungus Neurospora crassa, a model organism that is at the forefront of circadian rhythm research. The conservation of wild pollinators requires in-depth knowledge of their diversity, habitat requirements, and responses to environmental stress. how landscape cover and rainfall influences intra-tropical migration and During most years I teach at least one section of our foundation course Evolution, Ecology, Biodiversity & Conservation Biology BIOL 1001. Our Mission. A majority of species in the genus are distylous and strongly self-incompatible, while other species are self-compatible often having anthers and stigmas in close proximity, leading to high rates of self-fertilization. This research provides fundamental insight into the functioning of these organisms and furthers our knowledge on these medically-important species that have adapted to gorging on vertebrate blood and act as chief vectors of various human and animal diseases. We have been working towards a molecular genetic dissection of the distyly locus in Turnera species which determines both the incompatibility system and the floral dimorphism. (2007). Which hormones control reproductive behavior and related physiological processes? Bridget Stutchbury has a chest freezer stuffed with songbirds, a makeshift morgue that troubles her heart. The All agree that the spindle fibre that extends between chromosome and pole contains microtubules, and that the fibre propels the chromosomes poleward, but there is no agreement on how this is done. Research in the lab ranges from natural history and taxonomy to molecular phylogenetics and biogeography. Tarof et al. My research focuses on how the surrounding environment influences the gastrointestinal tract and digestion in fish species. Cytoskeleton 70: 241-259. Daphnia and Chaoborus) to examine aquatic ecosystem responses to a variety of human-induced stressors. Under freshwater conditions, where larvae face dilution of body fluids, the anal papillae of mosquitoes and midges take up salts (e.g. Bridget J. Stutchbury is a Canadian biologist, currently a Distinguished Research Professor and Canada Research Chair in Ecology and Conservation Biology at York University. Continued use of road-salt can ultimately lead to invasion of inland waters by salt-tolerant mosquito and midge species which inhabit coastal areas. "The idea that a 15-gram bird can fly non-stop over water for days is astounding," said Bridget Stutchbury, a professor of biology at York University in … E-mail—bstutch@yorku.ca. Stutchbury Lab . Further, gap junction–mediated electrical signals have a significant contribution to synaptic plasticity, learning and memory in health and disease.
