Lack of Foraging Site Fidelity Between Years by Common Nighthawks (Chordeiles minor)
(University of Notre Dame, 2021-01)Birds in the family Caprimulgidae generally exhibit high nest site fidelity, but it is not known if fidelity extends to foraging sites, especially for Common Nighthawks (Chordeiles minor), which are otherwise one of the ... -
Lake Zooplankton Carbon Sources: The Role Of Terrestrial Inputs And The Effects Of Depth And Taxonomic Composition
(University of Waterloo, 2008-11-28)The relative contribution of allochthonous and autochthonous production in zooplankton nutrition has been of interest since the net heterotrophy of lakes was recognised to be common. I measured the 13C signature of ... -
Lakes of the Peace-Athabasca Delta: Controls on nutrients, chemistry, phytoplankton, epiphyton and deposition of polycyclic aromatic compounds (PACs)
(University of Waterloo, 2012-02-07)Floodplain lakes are strongly regulated by river connectivity because floodwaters exert strong influence on the water balance, the physical, chemical and biological limnological conditions, and the influx of contaminants. ... -
Land Use and Climate Influence Marshes in the Northern Prairie and Parkland Region
(University of Waterloo, 2016-01-21)I evaluated the association between waterbird communities and agricultural activity at 48 non-permanent wetlands, and waterbird response to inter-annual climate variation at 24 non-permanent wetlands. I found six distinct ... -
Large-scale phylogenomic visualization and analysis of functional traits in bacteria
(University of Waterloo, 2019-01-24)The growth of genomic information in public databases has dramatically improved our view of the tree of life and at the same time expanded our knowledge of protein diversity. Through the use of automated annotation pipelines, ... -
Life history and population dynamics of Eastern Sand Darter (Ammocrypta pellucida) in the lower Thames River, Ontario
(University of Waterloo, 2009-06-17)Eastern Sand Darter (Ammocrypta pellucida) is listed as Threatened under the Canadian Species at Risk Act. Canadian populations are declining primarily due to the siltation of sandy depositional areas, the preferred habitat ... -
Life history characteristics of Lake Whitefish (Coregonus clupeaformis), Cisco (Coregonus artedi), and Northern Pike (Esox lucius) in rivers of the Hudson Bay Lowlands
(University of Waterloo, 2017-05-15)Many northern fishes display plasticity in life history and trophic ecology that can influence productivity of fisheries and bioaccumulation of contaminants, such as mercury. Cisco (Coregonus artedi), Lake Whitefish ... -
Life History of Dwarf Longnose Sucker (Catostomus catostomus) in the Elk River Watershed
(University of Waterloo, 2014-05-01)In 2004, a population of dwarf longnose sucker was discovered co-existing with the normal form within the Elk River Watershed of south-eastern British Columbia. This thesis evaluated morphological, genetic and life history ... -
Lipid and condition analyses of West Greenland marine feeding Atlantic salmon (Salmo salar L.)
(University of Waterloo, 2018-09-20)A regime shift in the Northwest Atlantic in the 1990s caused changes to the diet and productivity of marine-feeding Atlantic salmon (Salmo salar L.) off the West Greenland coast. Investigations into the implications of the ... -
Local and landscape drivers of aquatic biodiversity in urban stormwater management facilities
(University of Waterloo, 2022-05-20)Stormwater management facilities (SWMFs) are often constructed in urban areas to provide flood mitigation and runoff control, and thus replace some wetland functions. Yet, their suitability as habitat for wetland biota is ... -
Localization and possible functions of Arabidopsis HOTHEAD protein
(University of Waterloo, 2016-10-26)Molecular analyses using sixteen insertion-deletion polymorphic markers revealed that somatic sectoring occurs relatively frequently during the course of normal vegetative development. This is the first report that documents ... -
Long- and Short-Term Dynamics of the Wetlands in the Amboseli Savanna Ecosystem, Kenya
(University of Waterloo, 2006)The wetlands of the semi-arid savanna ecosystem of Amboseli are the critical dry-season range for a diverse wildlife population, as well as for livestock and humans. Changes in the migratory patterns and increases in ... -
Long-distance Movement over a Period of Days by a Female Myotis lucifugus in Newfoundland, Canada
(Humboldt Field Research Institute, 2021-02)Myotis lucifugus (Little Brown Myotis) is a regionally migrating bat, widely distributed throughout North America. Through long-term monitoring systems deployed in 2 locations in Newfoundland, Canada, we recorded the ... -
Long-term changes in spring phytoplankton community composition in five south-central Ontario lakes and their relations with spring water chemistry and climate
(University of Waterloo, 2019-05-23)Spring is an ecologically important period for phytoplankton communities, as environmental stressors such as acid deposition and recovery, climate warming, and shoreline development may exert strong influence at this time ... -
Long-term decline in bat activity using passive acoustic monitoring and an equipment correction factor in Nova Scotia, Canada
(University of Waterloo, 2020-09-28)Passive acoustic monitoring has grown in popularity as a technique to assess changes in activity levels of various taxa. However, there are few long-term and large-scale acoustic monitoring programs due to the current ... -
Long-term Effects of a Phragmites australis Invasion on Birds in a Lake Erie Coastal Marsh
(University of Waterloo, 2016-12-23)Invasive Phragmites australis threatens the integrity of essential bird habitat in coastal marshes. Located on the north shore of Lake Erie, Long Point, Ontario provides habitat to thousands of breeding and migrating birds, ... -
Long-term implantation of acoustic transmitters induces chronic inflammatory cytokine expression in adult rainbow trout (Oncorhynchus mykiss)
(Elsevier, 2018-11-01)Telemetry transmitters are frequently used in studies of wild fish migration and behavior. Although the effects of surgically implanted transmitters on survival, tag retention, healing and growth have been studied, there ... -
Magnetic Force Microscopy (MFM) Characterization of Superparamagnetic Nanoparticles (SPIONs)
(University of Waterloo, 2012-09-28)Superparamagnetic iron oxide nanoparticles (SPIONs), due to their controllable sizes, relatively long in vivo half-life and limited agglomeration are ideal for biomedical applications such as magnetic labeling, hyperthermia ... -
