The responsiveness of a wild population of Peromyscus maniculatus to the secondary plant compound 6-methoxybenzoxazolinone was tested. No obvious response was found in terms of the start of the breeding season, which was earlier in females on the control grid. This effect could be explained by higher average body weights of the females in the control population. Peromyscus maniculatus living in the coastal forest of southern British Columbia can be considered opportunistic breeders. Other experiments with 6-methoxybenzoxazolinone are reviewed, and guidelines for future research are proposed.

Clear Cutting

This study was designed to test the widely held hypothesis that clear-cut (logged) habitats support higher density populations of Peromyscus than do forested habitats. Deer mouse populations were livetrapped in forest and clear-cut habitats at Maple Ridge, British Columbia, from May 1975 to April 1978. The average density of mice per hectare in the forest was 19.6(1975), 15.8(1976), 22.3(1977), and on the clear-cut areas was 23.3(1975), 16.6(1976), 29.9(1977). The slightly higher number of animals on the clear-cutting in 1975 and 1977 reflected a burst of recruitment in the late summer and fall of each year. The density of mice on clear-cut areas declined during each winter to a level comparable with that of the forest. Juvenile male deer mice were able to enter into the clear-cutting populations during the breeding season in the first year after logging. Recently logged areas may be acting as dispersal or behavioural sinks.

Global Growth

The number of craft breweries in British Columbia has grown significantly in recent years,numbering over 140 in 2017. Very little is known about the effects of the craft brewery industryin British Columbia, specifically as it relates to impacts not related to brewery revenue and jobcreation. Beyond British Columbia, the craft beer industry has not empirically examined non-revenue impacts in a manner that reflects the global growth of the sector. Tourism experiences,such as those offered by craft breweries, are becoming increasingly important for resilience and sustainable growth and success of destinations. The goal of this research was to determine whovisitors to craft breweries are, how tourist and resident patrons differ, and what effects craftbreweries have on tourists who visit breweries. A 55 item survey was distributed at 11 craftbreweries in three regions in British Columbia during the summer of 2017. Results founddifferences between tourist and resident patrons in self-image congruency, age and travel partysize, but no difference in gender, education, or household income. From a tourism standpoint, itwas found that memories have a significant, positive impact on loyalty regarding the breweryand the destination. For tourists, strong connections were found between social involvement andboth authenticity and place attachment for those who were more socially involved in craft beer.Comparisons to previous research in the wine industry provide additional commentary.Implications for craft breweries, destinations, and future research in this area are discussed.

A study was conducted to the determine the effects of concentrate supplimentation on performance and nutrient digestibility in cane-rats/grasscutters. There were initiall three treatments: 0%, 10% and 20% concentrate supplementation onas fed basis to a basal elephant grass diet. Fifteen weaned cane-rats with average body weights of 1150g(士365.40) were randomly assigned to the three treatments based on weight and sex. The growth study was conducted for eight weeks. A nutrient digestibility study was also conducted using three grasscutters per treatment. The cane-rats fes 20% supplementary concentrate gained more weight than those offered 10% concentrate feed. Crude protein was better (p<0.05) digested by cane-rats on 20% concentrate feed whereas, ash and ether extract digestibility were better on 10% concentrate feed. The 0% concentrate treatment was terminated because three of the cane-rats(68% mortality) died within three weeks of the study. It is recomendedfrom this study that cane-rats fed a basal grass diet should be supplemented with 20% concentrate on as fed basis

Alcohol Sales

Alcohol sales data provide a more accurate indication of alcohol consumption than alternative methods such as population surveys. This information can be used to better understand epidemiological issues related to alcohol consumption, policy development and evaluation. Official sales records were collected for the 28 regional districts of British Columbia (BC) for 2002–2005, while homemade alcohol was estimated from survey data. Alcohol consumption rates were found to vary across geographic regions, by season, and with population level demographics. Government stores were the largest source of alcohol consumption in BC, accounting for 45.1% of total alcohol consumption in 2004. U-Brews/U-Vins accounted for 4.0%, private liquor stores accounted for 27.5% of the total, and homemade alcohol made up 4.3% of total alcohol consumption. Analysis also revealed that the average alcohol concentration in wines (12.53%) and coolers (6.77%) has been underestimated by Statistics Canada. The feasibility of developing this type of alcohol monitoring system is examined. Finally, implications for the development of targeted public health initiatives and future research are discussed.

Total body weight of 9749 reindeer calves and 4798 adult reindeer were measured from 1984 to 1999 on the Seward Peninsula, western Alaska, USA. Growth rates of male and female calves, and annual growth patterns of adults were determined. Male calves grew faster than female calves. Reproductive females were lighter than non-reproductive females during summer but there was no effect of reproduction on average body weights the following winter. Adult males age 3-5 were heavier during summer than winter. Castrated males weighed the same as uncastrated males in summer, but were significantly heavier in winter, and did not display the large annual fluctuations in weight typical of reproductive males and females. Growth rates were higher and body weights greater in this herd than many other cir-cumpolar reindeer populations. We suggest these kinds of physiological indices should be used to monitor the possible effects of spatial and temporal variation in population density and to evaluate changes in herding practices.
