Past Projects
Evaluating Eco-schools on sustainable sites initiatives (SSI) framework (2012)
Master's thesis, Faculty of forestry, University of Toronto
International leader on sustainable building design is the Leadership in Energy and Environmental Design program (LEED), which is a third party certification program used to evaluate building designs and construction strategies targeting to improve environmentally sustainable practices within architectural plans. In 2013, LEED introduced Sustainable Sites Initiative (SSI), which is an evaluation method of sustainability on sites. It extends its focus of sustainability from just the building to the landscape level. These international standards can only help further bring environment and ecological sustainability to the forefront. Some of our productive urban forests can be found on school grounds. The Toronto District School Board (TDSB) is the largest school board in Canada as well as one of the largest land holders in the City of Toronto; thus one of the largest holders of Toronto’s urban forest. TDSB has come up with a certification program called the EcoSchool Program, to evaluate the level sustainability on school grounds. As part of her master's dissertation, Janani evaluated the comparability of EcoSchool certification at the platinum level in school ground greening category to the vegetation criteria set by the international Sustainable Sites Initiative (SSI) framework.
Functional uniqueness of non-native species in abandoned, semi-natural rural habitats (2011)
Undergraduate Researcher, Cadotte lab, Department of biological Sciences, University of Toronto Scarborough (UTSC)
Understanding how species can successfully invade habitats has been a long-standing research objective for ecologists. In partnership with the University of Toronto's Koffler Scientific Reserve, as an undergraduate researcher, along with her advisor Dr. Marc Cadotte, Janani took the lead to further explain how non-native plants successfully invade communities because of their functional fit to local conditions and overlap with resident species. In this study, they analyzed 624 known plant species to see how different functional traits explain the success of non-native plant species in an exotic dominant grassland
Nutrient Network- NutNet (2010)
Undergraduate Volunteer, University of Toronto's Koffler Scientific Reserve
The Nutrient Network (Nutnet) is a grassroots research effort to address the fundamental and applied questions in ecology, ultimately trying to produce a global dataset that can be used to determine general productivity-diversity relationships and biodiversity patterns caused by eutrophication in terrestrial ecosystems. This global research cooperative network comprises more than 40 grassland sites worldwide including Koffler Scientific Reserve. Along with the project leads, Dr. Robin Marushia & Dr. Marc Cadotte, Janani helped maintain the field site by altering nutrient levels and gathering data from the field.
Genetic diversity and Ecosystem Functioning (2010)
Undergraduate Volunteer, Cadotte lab, Department of biological Sciences, University of Toronto Scarborough (UTSC)
Along with the project lead, Nicholas Mirotchnick, Janani helped gather functional traits on plants to determine evolutionary relationships to each other to estimate the functional and phylogenetic diversity of each community.
