The main presentation will be: BNS Scholars Student Research Symposium There will be presentations by three past recipients of the BNS Scholarship= . Come and see some of the research that is taking place in the Biology Dep= artment at Acadia University. Determining the presence of arbuscular mycorrhizal fungi in two salt marsh = grass species by Tyler D=92Entremont Arbuscular mycorrhizal fungi (AMF) provide water and essential mineral nutr= ients in symbiotic relationships with over 80% of all vascular land plants.= These organisms allow plants to inhabit hostile environments by acting as = an extended root network to ensure the success of the species. Saltmarshes,= among these hostile environments, are crucial nursery habitats for a varie= ty of juvenile fish and invertebrate species, which form the foundation of = many marine and terrestrial food chains. With salt marshes declining worldw= ide, efforts to improve the success of salt marsh restoration projects has = never been more paramount. This research examines two salt marsh grass spec= ies, Spartina alterniflora Loisel and Spartina patens Aiton, via fungal sta= ining, nested polymerase chain reaction and rDNA sequencing to determine th= e AMF species present within their roots. The use of these identified mycor= rhizal species, as well as their colonization rates, may be used in future = restoration projects to increase the probability of successful colonization= by these saltmarsh grasses. Reintroduction of seed bank derived Geum peckii (Eastern Mountain Avens) on= Long Island, Digby County, Nova Scotia by Sarah Fancy G. peckii is one of Canada=92s most endangered plant species. In Canada it = is found on Brier Island, Digby County, globally the only other population = is in the mountainous regions of New Hampshire. The Nova Scotia Department = of Natural Resources supports a seed bank population of G. peckii seeds at = Acadia University. For this research project the seed bank was used to esta= blish a population of G. peckii in tissue culture, the plants were then put= back into their natural habitat to evaluate plant success. The outplanting= of endangered tissue culture material is a first for Nova Scotia and it is= a relatively new technique globally. To date the project shows a 100% succ= ess rate. Modelling the behaviour of striped bass (Morone saxatilis) in Minas Passage= , Nova Scotia by Kody Crowell Tidal energy development in the Bay of Fundy has been an active area of res= earch for the past few decades, however, the ecological impact that in-stre= am tidal turbines pose to the surrounding environment has sparked much cont= roversy. As such, there has been an increased demand for monitoring and con= sultation. Several species, especially the striped bass (Morone saxatilis),= are known to spend a significant amount of time near the berth sites, and = their level of activity may be dependent on the season =96 recent studies i= nvolving acoustic tracking of the fish suggest that the species has a lower= metabolic rate in the winter, thereby limiting its ability to detect and a= void turbine infrastructure, acting as =93inert=94 particles. Modelling the= movement of such a species using agent-based models and the Finite Volume = Community Ocean Model (FVCOM) in the Minas Passage is one way of predicting= whether an animal will pass near a turbine. Individual-Based Models were u= sed to model fish behaviour and suggest where Striped Bass might spend a ma= jority of their time in the winter and summer seasons. Results were in gene= ral agreement with observation, which suggests that striped bass prefer the= deeper waters on Minas Passage in colder weather. Future studies will incl= ude the addition of in-stream tidal turbines for the winter model.
