Biodiversity changes since the last Ice Age reconstructed from lake sediment cores
Principal Investigator: Herzschuh, Ulrike
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5941. Our aim for this study would be to better understand the climate history and paleoecological since the last glacial maximum at the margin of glaciated regions and to help compare regions between formerly glaciated and unglaciated regions in terms of changes in biodiversity, the movement of the tree line and the effec...


Indigenous Knowledge of Berries in the Northwest Territories
Principal Investigator: Singer, Claire L
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5495. The goal of this project is to complete a territory-wide Indigenous knowledge study to determine what we know about berries, describe any changes that are being seen in berries, identify potential causes of these changes, and outline what further information needs to be collected. The completion of this work will resu...


Freshwater biodiversity spanning contaminant gradient from historical gold mines in Yellowknife NWT region
Principal Investigator: Derry, Alison
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5253. The long-term project objective is to determine ecological and evolutionary processes, and interactions between ecology and evolution (eco-evolutionary interactions), that are potentially limiting and/or facilitating the biological recovery of mining-impacted lakes around Yellowknife, NWT. The objective in the first y...


Classification, mapping, monitoring, quantification, and inventory of key ecosystem properties of terrestrial ecosystems in the NWT mainland, adjacent to Victoria Island
Principal Investigator: McLennan, Donald S
Licensed Year(s): 2019
Summary: The objectives of this project are to: 1. investigate, characterize and sample the vascular plant, moss, lichen, fungal and algal flora and biodiversity; 2. describe, sample and characterize various terrestrial ecosystems of Northwest Territories; 3. identify in the landscape as many as possible of the characterized terrestrial ecosystems, and document their occurrence by geo-referenced digital...


Biomonitoring 2.0: biodiversity assessment in Slave River tributaries
Principal Investigator: Baird, Donald J
Licensed Year(s): 2014 2013
Summary: This project will assess the biodiversity in the Slave and Dog Rivers, NWT, using a variety of collection methods, to support the establishment of baseline biomonitoring conditions, and to explore the use of DNA-based identification of animals, plants and microorganisms. The food webs of these systems will also be described using stable isotope techniques. The project will contribute to the wider ...


Carbon Cycling Linkages of Permafrost Systems [CYCLOPS]
Principal Investigator: Williams, Mathew
Licensed Year(s): 2014 2013 2012
Summary: The aim of the proposed project is to develop, parameterize and evaluate a detailed process-based model of vegetation soil- permafrost interactions using data collected through directed field campaigns in the discontinuous and sporadic permafrost zones of western Canada. The research team will (i) elucidate the role of plant biodiversity in controlling permafrost status in contrasting ecosystems w...


Late Cretaceous Palaeontology of northwestern Northwest Territories, Canada
Principal Investigator: Vavrek, Matthew J
Licensed Year(s): 2013
Summary: This project is a continuation of the collaborative research program on ancient biodiversity in the Canadian Arctic. Recently, the group completed work supported by Polar Continental Shelf Project in the Brackett Basin in the westcentral Northwest Territories and the Bonnet Plume Basin in northeastern the Yukon Territory, during which the research team recovered both new vertebrate (dinosaur) foss...


Palaeontology of the Summit Creek Formation, western Northwest Territories, Canada
Principal Investigator: Vavrek, Matthew J
Licensed Year(s): 2012
Summary: The research team will be prospecting for and collecting Cretaceous fossils from the Summit Creek Formation in order to better understand what terrestrial biodiversity was like at high latitudes at that time. This project is a continuation of the collaborative research program on ancient biodiversity in the Canadian Arctic. Recently, the research team completed work supported by Polar Continental ...


Ecological Structure of Northern Arthropods: Assessing community structure and biodiversity across an environmental gradient
Principal Investigator: Buddle, Chris
Licensed Year(s): 2012 2011
Summary: The objectives of this research project are: (1) To test how and to what degree the structure of arthropod communities changes between the northern boreal and sub-arctic zones. This will provide us with a contemporary geographic profile of species and group distributions as well as estimates of diversity. (2) To use molecular genetic techniques to aid in species identification and to help expl...


A phylogenetic and phylogeographic study of predaceous diving beetles in the Nearctic with a focus on the tribe Agabini (Coleoptera, Dytiscidae, Colymbetinae).
Principal Investigator: Venables, Chandra
Licensed Year(s): 2011
Summary: The objectives of this research project are to: 1) establish evolutionary relationships of diving beetles in the Nearctic, in addition to identifying colonization routes for exemplars in the tribe Agabini; 2) assess genetic diversity of target species and among-population genetic mixing, and compare these data to historical data (where possible) with an aim at assessing latitudinal and historica...
