Prevalence and evolution of core photosystem II genes in marine cyanobacterial viruses and their hosts
(2006-08)Cyanophages ( cyanobacterial viruses) are important agents of horizontal gene transfer among marine cyanobacteria, the numerically dominant photosynthetic organisms in the oceans. Some cyanophage genomes carry and express ... -
Prey Exchange Rates and the Impact of Predators on Prey Populations in Streams
(1990)We present four lines of evidence that the magnitude of prey exchange (=immigration/emigration) among substrate patches has an overwhelming influence on the perceived effects of predators on prey populations. (1) An extensive ... -
The Price of Gold: An Analysis of the Financial Costs of LEED Certification and the Role of LEED in Meeting Dalhousie’s Sustainability Objectives
(2016-04)The Leadership in Energy and Environmental Design (LEED) Green Building Rating System, now plays a major part in the design process of many major construction projects. Dalhousie University is no exception, having a ... -
The Price of Plastic: An Analysis of the Environmental and Economic Impacts and Social Perceptions of Single-Use Plastic Containers at Dalhousie University
(2019-04)While recyclable, landfills house 22 to 43% of plastics (Gourmelon, 2015, p. 2). Plastic packaging comprises the majority of plastic waste (Brooks et al., 2018, p. 1). With rises in plastic production (Gourmelon, 2015, ... -
Primary production by suspended and benthic microalgae in a turbid estuary: Time-scales of variability in San Antonio Bay, Texas
(1996-12)The within-day, between-day and month-to-month variability of light attenuation and microalgal chlorophyll a (chl a) and photosynthetic response was measured in San Antonio Bay, Texas, USA. Waters were shallow (<2 m) ... -
Primary Production Estimates from Recordings of Solar Stimulated Fluorescence in the Equatorial Pacific at 150-Degrees-W
(1992-01)Biological, optical, and hydrographical data were collected on the WEC88 cruise along 150-degrees-W and during a 6-day time series station on the equator during February/March 1988. This area was characterized by a subsurface ... -
Primiparous and multiparous females differ in mammary gland alveolar development: implications for milk production
(2012-08)Mammary gland capacity is influenced by the number of secretory cells in the gland, the activity of those cells and the size and arrangement of the alveoli that they form. Although reproductive experience has been shown ... -
Prioritizing Design Elements for a Sexton Campus Bike Space
(2016-04)In an effort to expand Dalhousie University Sexton campus (as herein referred to as Sexton campus) services the Innovative Design in Architecture and Engineer (IDEA) building has been proposed for construction in ... -
Pro-active solutions for Atlantic salmon management in Nova Scotia: A roadmap for recovery
(2019-03)The Atlantic salmon (Salmo salar) is an anadromous fish species native to Nova Scotia that has significant economic, ecological, and cultural value to the people of the province. Atlantic salmon have been in decline ... -
Probability and mitigation of vessel encounters with North Atlantic right whales
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, 2009-03)Successful mitigation of vessel-whale encounters requires quantitative estimates of vessel strikes, how strike rates change over time, where strikes are most likely to occur, and options for minimizing strikes. In addressing ... -
Probing the depths of the India-Asia collision: U-Th-Pb monazite chronology of granulites from NW Bhutan
(2011-03)Rocks metamorphosed to high temperatures and/or high pressures are rare across the Himalayan orogen, where peak metamorphic conditions recorded in the exposed metamorphic core, the Greater Himalayan Sequence (GHS), are ... -

Procedural effects of prey tethering experiments: Predation of juvenile scallops by crabs and sea stars
(1994)This study examines the effects of an experimental tethering procedure often used in field predation experiments. In laboratory experiments, juvenile sea scallops Placopecten magellanicus, either free or tethered, were ... -
