Recurrent outbreaks of disease in sea urchins Strongylocentrotus droebachiensis in Nova Scotia: Evidence for a link with large-scale meteorologic and oceanographic events
(1997-06)Recurrent outbreaks of a disease (paramoebiasis, caused by a marine amoeba Paramoeba invadens) result in mass mortalities of sea urchins Strongylocentrotus droebachiensis in the rocky subtidal zone of the Atlantic coast ... -
Redox state of the South Mountain Batholith: A reconnaissance study using zircon geochemistry
(2019-05-15)The late Devonian South Mountain Batholith (SMB) of Southwestern Nova Scotia is the largest plutonic igneous body emplaced during the Appalachian orogeny, with a current surface expression of 73,000 km2. The batholith ... -
Redshift Determination and CO Line Excitation Modeling for the Multiply-Lensed Galaxy HLSW-01
(2011-04-20)We report on the redshift measurement and CO line excitation of HERMES J105751.1+573027 (HLSW-01), a strongly lensed submillimeter galaxy discovered in Herschel/SPIRE observations as part of the Herschel Multi-tiered ... -
A Redshift Survey of Herschel Far-Infrared Selected Starbursts and Implications for Obscured Star Formation
(2012-12)No abstract available. -
A Redshift Survey of the Submillimeter Galaxy Population
(2005-04)We have obtained spectroscopic redshifts using the Keck-I telescope for a sample of 73 submillimeter (submm) galaxies for which precise positions are available. The galaxies lie at redshifts out to z=3.6, with a median ... -
Reduced Retinal Function in the Absence of Na(v)1.6
(2012-02)Background: Mice with a function-blocking mutation in the Scn8a gene that encodes Na(v)1.6, a voltage-gated sodium channel (VGSC) isoform normally found in several types of retinal neurons, have previously been found to ... -
Reducing Disposable Cups on Dalhousie Campus: A Second Cup Case Study
(2008-04)An enormous amount of waste is being generated on campus through the use of disposable cups. Massive amounts of waste are generated by coffee cups each week and are sent to landfills. Landfills are unsustainable and cause ... -
Reducing risks from E. coli 0157 on the organic farm
(Canadian Centre for Sustainable Agriculture, Saskatoon, Saskatchewan., 2001)E.coli 0157 is a bacterial pathogen of the human intestinal tract which is carried in certain species of livestock and wildlife without ill effect. Such organisms are termed zoonotics. Various types of Campylobacter and ... -
Reducing the energy use in Dalhousie residences through infrastructural and behavioral changes
(2007-04)Dalhousie University is one of the leading institutions of higher learning in Canada. Over the years, it has taken a leadership role through signing both the Talloires and Halifax Declarations, committing itself to teach ... -
Reducing the risk of lethal encounters: vessels and right whales in the Bay of Fundy and on the Scotian Shelf
(2008)The North Atlantic right whale Eubalaena glacialis is endangered, in part, due to vessel-strike mortality. We use vessel traffic and right whale survey data (similar to 3 nautical miles [n miles], similar to 5.6 km resolution) ... -

Reflections on the failure of traditional fisheries management
(2017-01)A traditional fisheries management or fish stock assessment takes a Lamarckian-like instructive view of fisheries science that involves an inductive monism. Its invalid inductive arguments have no problem solving capacity ... -
Reflections on the failure of traditional fisheries management
(2016-06-03)A traditional fisheries management or fish stock assessment takes a Lamarckian-like instructive view of fisheries science. Its invalid inductive arguments have no problem solving capacity and are responsible for the collapse ... -
A Refraction Seismic Survey of Martinique Beach: Geometry and Significance to Barrier Beach Evolution
(1985-04-15)During the summer of 1984 a refraction seismic survey was conducted at Martinique Beach using a 12 geophone array and seismic recorder with a hammer plate as the acoustic source. Sixteen sites were occupied along the 3.5 ... -
Refuge dynamics and metapopulation dynamics: An experimental test
(1996-03)Red scale, an insect pest of citrus, is under control by the parasitoid Aphytis melinus in many areas, and in our study area the interaction appears dynamically stable. The bark on the interior branches and trunk of trees ... -
A Refuge for Red Scale the Role of Size-Selectivity by a Parasitoid Wasp
(1989)The presence of a physical refuge (an area where mortality due to parasitism is very low) has been demonstrated for California red scale, a pest of citrus. Density of red scale is very high, and parasitism by the principal ... -
