A histochemical study of Erysiphe graminis hordei El. Marchal on barley with particular reference to penetration and the phosphatase activity of the haustoria
(1956)
New and highly refined physiological techniques have largely replaced the descriptive methods of classical cytology originally used in the investigation of host-parasite relations (Shaw and Samborski, 1956; Samborski and ...
Sex, friends, and disease: social ecology of elk (Cervus elaphus) with implications for pathogen transmission
(2011)
Many mammals are social. The most basic social behaviour is when the actions of one conspecific are directed toward another, what we call the ‘dyadic interaction’. Both intrinsic and extrinsic factors may affect an ...
Characterization of regulation of expression and nuclear/nucleolar localization of Arabidopsis ribsomal proteins
(2011-06)
Ribosomal proteins (RPs), synthesized in the cytoplasm, need to be transported from the cytoplasm to the nucleolus (a nuclear compartment), where a single molecule of each RP assembles with rRNAs to form the large and small ...
Endocytosis of cationized ferritin by soybean (glycine max L.) protoplasts
(1987)
Protoplasts derived from soybean SB-I suspension cell
cultures were incubated in buffered osmoticum containing
cationized ferritin (CF) or native ferritin (NF) to
demonstrate the process of endocytosis in plant ...
Rehabilitation studies on saline land caused by potash mining activity
(1989)
The salinity at the waste management areas at potash mines is extreme.
Saturated brine seeps from the tailings pile and contaminates the surrounding
land killing vegetation and affecting soil structure. Conventional ...
Fossil flora of the Paleocene Ravenscrag Formation, southwestern Saskatchewan, Canada
(1989)
The Paleocene Ravenscrag Formation of southwestern
Saskatchewan, Canada, is a lignite-bearing clay, silt, and
sand unit which, in places, bears abundant, well preserved
plant fossils. These sediments conformably ...
High temperature stress and flowering in brassica napus L.
(2003-06-02)
High temperature stress (HTS) adversely affects reproduction in most plant species studied to date. HTS during flowering may result in an almost total inhibition of seed production in crop plants. Increasing our knowledge ...
Population dynamics of a beaver population in northern latitudes
(1965)
The first thorough investigation of the status of beaver populations in Wood Buffalo National Park was reported by Soper (1937). At that time the lowlands of the Peace and Athabasca deltas were largely devoid of beaver, ...
Comparison of the bacteria within ticks from allopatric and sympatric populations of Dermacentor andersoni and Dermacentor variabilis near their northern distributional limits in Canada
(2011-06)
Understanding the ecology and epidemiology of tick-borne diseases requires detailed knowledge of the complex interactions among the tick vector, the microorganisms they carry and the vertebrate hosts used by ticks, as well ...
The role of dispersal in population dynamics of breeding Ross's geese
(2006-04-06)
Spatial variation in density of organisms can lead to challenges in estimation of population size. Associated vital rates responsible for this variation also may vary geographically and in response to local ecological ...
