Several salt compounds were tested in vitro as inhibitors of Erwinia carotovora subsp. atroseptica (van Hall) Dye (Eca) and Erwinia carotovora subsp. carotovora (Jones) Bergey, Harrison, Breed, Hammer & Huntoon (Ecc), causal agents of bacterial soft rot of potato. All compounds were mixed with p...

The aim of this study was to examine the effects of various biological factors such as body mass, trophic level, climate and geography on census area in terrestrial mammals. The effects of census area on the population density-body mass relationship were also examined. The geographic areas covered i...

• Dispersal may be favoured at geographic range edges by unstable population
and metapopulation dynamics. However, dispersal may also evolve in response to
geographic variation in other life-history traits, especially the mating system. Here,
increased dispersal at range margins was te...

The cause of size differences among developing fish is often not clear. We examined variability in egg size and in incubation time to determine whether either influenced hatching size or initial rates of growth in Japanese Medaka. We also tested the prediction that larger females should produce heav...

This study was designed to examine the ability of pertussis toxin to block various responses due to (-)-baclofen in cultured cerebellar granule neurons of the rat. Treatment with pertussis toxin for 3 h markedly reduced the ability of (-)-baclofen to stimulate GTPase in membranes, and its ability to...

In vitro growth of R. culicivorax preparasites was monitored in 2 culture media under differing conditions of crowding. Crowding was more important that the character of the medium itself in stimulating in vitro growth. The glycogen, protein, and lipid content of nematodes that had developed after 5...

The recent detection of the invasive colonial tunicate Diplosoma listerianum in Havre- Aubert, Magdalen Islands (Quebec, Canada) in 2008, prompted the development of a molecular assay as a method to detect and monitor for the potential invasion of this species in Prince Edward Island. The aim of thi...

The hydraulic habitat of 12 sites in a small salmon stream in central New Brunswick was investigated between 1992 and 1995 to determine patterns of habitat (substrate) stability between and within reaches. Stability was evaluated by measuring particle size distribution in replicated erosional and de...

This modification to the technique of epi-illumination light microscopy makes use of a new system of lenses that replaces expensive and not readily available dipping cone objectives. The newer objectives offer at least comparable resolution and depth of field, along with simple preparation procedure...

Greenhouse trials were conducted to evaluate the effect of treating adult and egg stages of Choristoneura fumiferana with Insegar, a water-based commercial formulation of the juvenile hormone analogue fenoxycarb, or with water (controls) at droplet sizes and densities comparable to those achieved th...

Substance P (SP), injected intrathecally, produced a dose-related increase in responsiveness (hyperalgesia) in a pressure test for nociceptive thresholds. Pretreatment with two doses of SP produced complete desensitization to this response but did not alter base-line responsiveness. The hyperalgesic...
