The investigation of edge effects within ragmented forest islands in Short Hills Provincial Park
(Brock University, 1994-10-02)
It has been well documented, within the field of landscape ecology, that terrestrial fragmentation contributes to increased heterogeneity at the landscape level. It has also been observed that elevated areas of edge ...
Irrigation scheduling for Sovereign Coronation grapevine based upon evapotranspiration calculations and crop coefficients /
(Brock University, 2007-06-01)
Several irrigation treatments were evaluated on Sovereign Coronation table grapes at two sites over a 3-year period in the cool humid Niagara Peninsula of Ontario. Trials were conducted in the Hippie (Beamsville, ON) and ...
Foraging ecology and parental care of common terns (Sterna hirundo) nesting in Windermere Basin, Lake Ontario
(Brock University, 1993-10-02)
The relationships among chick feeding, size and type of prey item, and foraging time away from the brood have not been well studied in seabirds. This study investigated spatial and temporal patterns of foraging and ...
Postglacial variations in aquatic productivity in Found Lake, Ontario
(Brock University, 1979-07-09)
Pigment orientation changes detected by low temperature linear dichroism spectroscopy: cold-hardening transition in phycobilisome-containing organisms
(Brock University, 1992-10-02)
Low temperature (77K) linear dichroism spectroscopy was used to characterize pigment orientation changes accompanying the light state transition in the cyanobacterium, Synechococcus sp. pee 6301, and cold-hardening in ...
Primary structure and expression studies of the dihydrofolate reductase gene (DFRI) of Saccharomyces cerevisiae
(Brock University, 1986-07-09)
The nucleotide sequence of a genomic DNA fragment thought previously to contain the dihydrofolate reductase gene (DFR1) of Saccharomyces cerevisiae by genetic criteria was determined. This DNA fragment of 1784' basepairs ...
An examination of transcriptional and translational regulation of the 70kDa heat shock proteins following amputation of the tail and forelimb in the newt Notophthalmus viridescens
(Brock University, 1995-11-04)
Several stresses to tissues including hyperthermia, ischemia, mechanical trauma and heavy metals have been demonstrated to affect the regulation of a subset of the family of heat shock proteins of70kOa (hsp70). In several ...
Proton translocation by cytochrome c oxidase reconstituted into proteoliposomes
(Brock University, 1984-07-09)
Cytochrome c oxidase .inserted into proteoliposomes translocates protons with a stoichiometry of approx-, imately 0.4-0.6 H+/e- in the presence of valinomycin plus pottasium. The existance .ofsuchproton translocation is ...
Development of packaging cell lines for rescuing BAV2 viral vectors
(Brock University, 1999-07-09)
The construction of adenovirus vectors for cloning and foreign gene expression requires packaging cell lines that can complement missing viral functions caused by sequence deletions and/or replacement with foreign DNA ...
Does Gamma-aminobutyric acid function as a plant resistance mechanism against phytophagous insect activity? /
(Brock University, 2000-05-21)
Gamma-aminobutyric acid (GAB A) is a ubiquitous non-protein amino acid synthesized via the decarboxylation of L-glutamate in a reaction catalyzed by the cytosolic enzyme L-glutamate decarboxylase (GAD). In animals it ...
