How quality of host plant affects a predator-prey interaction in biological control
(1995)In cases of successful biological control the pest population is maintained at low densities by a natural enemy, but the mechanisms by which the predator or parasitoid manages to control the pest are often unknown. This ... -
How Rocks Affect the Growth of Krummholz in the Mealy Mountains of Labrador
(2009-04)The purpose of this thesis is to investigate how rocks affect the growth of coniferous krummholz of two species: Black Spruce (Picea mariana) and Balsam Fir (Abies balsamea). Specifically, I investigated: 1) whether ... -
How should we measure poverty in a changing world? Methodological issues and Chinese case study
(2007)No abstract available. -
How the Consumption Habits of Students on Dalhousie Studley Campus Would be Impacted by the Implementation of More Sustainably Operated Food Organizations
(2023-04)The objective of this research study was to understand how the implementation of more sustainably operated food organizations at Dalhousie University would influence the consumption habits of students on Studley campus. ... -
An HST/ACS View of the Inhomogeneous Outer Halo of M31
(2009-03-19)We present a high precision photometric view of the stellar populations in the outer halo of M31, using data taken with the Hubble Space Telescope Advanced Camera for Surveys (HST/ACS). We analyse the field populations ... -
The Hubble Deep Field North SCUBA Super-map - I. Submillimetre maps, sources and number counts
(Blackwell Publishing, 2003)We investigate the emission of submillimetre-wave radiation from galaxies in a 165 arcmin<SUP>2</SUP> region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and ... -
The Hubble Space Telescope GOODS NICMOS Survey: Overview and the Evolution of Massive Galaxies at 1.5 < z < 3
(2010-10-06)We present the details and early results from a deep near-infrared survey utilising the NICMOS instrument on the Hubble Space Telescope centred around massive M_* > 10^11 M_0 galaxies at 1.7 10^11 M_0, whereby we find an ... -
Hubble Space Telescope images of submillimeter sources: large, irregular galaxies at high redshift
(2003-12)We present new Hubble Space Telescope STIS, high-resolution optical imaging of a sample of 13 submillimeter (submm) luminous galaxies, for which the optical emission has been pinpointed either through radio-1.4 GHz or ... -
A Hubble Space Telescope NICMOS and ACS Morphological Study of z~2 Submillimetre Galaxies
(2010-02-12)We present a quantitative morphological analysis using HST NICMOS H160- and ACS I775- band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which have redshifts between z=0.7-3.4. Our analysis also ... -
Humanizing Marine Spatial Planning: A Salutogenic Approach
(2021-12)Despite the growing acknowledgement within the academic literature that human well-being is an important aspect of marine spatial planning (MSP), research and practice continue to neglect this concept. Specifically, the ... -
Hybridization effects on phenotypic plasticity: experimental compensatory growth in farmed-wild Atlantic salmon
(2011-05)Compensatory growth (CG) is a means by which organisms can increase their growth rate above their routine growth rate after a period of environmentally induced growth depression. Despite a focus on the implications of ... -
Hydrogeologic Investigation of the Cumberland Central Landfill.
(2000-04-15)The County of Cumberland has used a large tract of Crown Land near Springhill Junction as their main municipal waste disposal site since 1978. The site was initially commissioned as a first-generation landfill, known as ... -
Hydrothermal Alteration, Gold Distribution and Geochronology of Epithermal Gold Mineralization in the Copiapo Volcanic Complex, Chile
(1986-04-15)This thesis is a pilot project of an ongoing investigation into the gold metallogenesis in the Copiapo volcanic complex, Chile. The study is aimed at understanding the pattern of hydrothermal alteration and its relation ... -
Hydrothermally Deposited Carbon Coatings for Li-Ion Battery Active Materials Postprint
(IOPscience, 2023-08-14)Hydrothermally deposited carbon coatings were evaluated for Li-ion battery materials. The applied coatings were found to be highly uniform and porous, with a density of 1.89 g/ml and a surface area of 370 m2/g. In lithium ... -
The hygroscopicity parameter (kappa) of ambient organic aerosol at a field site subject to biogenic and anthropogenic influences: relationship to degree of aerosol oxidation
(2010)Cloud condensation nuclei (CCN) concentrations were measured at Egbert, a rural site in Ontario, Canada during the spring of 2007. The CCN concentrations were compared to values predicted from the aerosol chemical ...
