Understanding the components of the forest value chain and linkages is essential in designing a system that will maximize the economic value of Canadian fibre. A key part of the system is how firms incorporate the fibre quality and attributes of their timber supply into the decision over what kinds of products to manufacture. The linkage between timber supply and how firms decide to utilize fibre is critically important, especially in Canada, where government policy plays a key role in governing access to fibre. We explore this question by looking at whether firms try to maximize the economic return from their fibre, or instead focus on other objectives such as maximizing the production volume they can generate from their timber supply. We surveyed sawmills and woodland managers in British Columbia in the Fall of 2006 and focused on a particular characteristic—the extent to which sawmills and operations are responding to value-based signals rather than to other kinds of signals. We found that the majority of BC forest sector firms we interviewed are emphasizing volume-based measures on a daily basis, whether they are in sawmill or woodlands operations, and while economic measures become more important as the period lengthens, it is unclear as to how firms reconcile these 2 different types of measures. Key words: organizational behaviour, firm operations, Canadian forest industry, value chain optimization

Evolution Of Mammals

From 1890 to 1899, the Reverend John Henry Keen collected plants and animals in the vicinity of the Anglican mission at Massett, on the north-central coast of the Queen Charlotte Islands (Haida Gwaii), British Columbia, Canada. Keen's prodigious collecting efforts resulted in the first detailed information on the natural history of that region, particularly of the beetle fauna. Keen also observed and collected mammals, depositing specimens in museums in Canada, England and the United States, for which a catalogue is given. Several mammal specimens provided the basis for new distributional records and nine new taxa, two of which were named for Keen. In 1897, Keen prepared an annotated list of ten taxa of land mammals of the Queen Charlotte Islands, including the first observations of natural history for some of the species. Particularly important were the insightful questions Keen raised about the evolution of mammals isolated on the Islands, especially why certain species, abundant on the mainland, were absent.

Past work suggested that size-selective harvesting of large fish combined with heritability of body size has caused the large (up to 34%) decrease in mean adult weight of British Columbia pink salmon (Oncorhynchus gorbuscha) since 1950. In a companion paper (Can. J. Fish. Aquat. Sei. 49: 1294–1304) we evaluated the statistical performance of a large-scale fishing experiment that could enable managers to test this hypothesis and at the same time increase catch biomass if that hypothesis were correct. In this paper we evaluate the economic performance of the proposed experiment using Monte Carlo simulation and decision analysis under a wide range of conditions that encompasses existing biological uncertainties. We accounted for uncertainties through prior probabilities placed on two key biological hypotheses. We computed the expected economic value of catch biomass for the experimental and current nonexperimental (status quo) management strategies using a 20-yr time horizon and a 10-yr experiment with four spatial replicates. Under a variety of discount rates, the expected economic value of experimentation exceeded that of status quo management in most of the conditions examined, in some cases by as much as 60%.

Charitonetta albeola is a common summer visitant to parts of the interior of British Columbia and is abundant on the coast region in winter. Adults arrive in the interior in advance of the yearlings and the sex ratio in early spring flocks is predominantly male. Later, both age groups associate for a short time, then the paired adults become established on nesting territories. Most of the yearling males, and subsequently the adult males, disappear for six weeks or longer. They eclipse and begin to appear again on certain lakes in August but are not plentiful until late September or early October. The yearling females remain on the breeding grounds in flocks throughout the summer. Courtship which is observed first on the coast in March reaches its greatest intensity on the interior lakes in April. Males vigorously defend their nesting territories. Eggs are laid in May and by the last week of June most of the young have appeared. Breeding females leave their broods in order to moult before the young have reached the flying stage and associate with flocks of yearling females that have gathered on certain waters where food is abundant. At this time all are excessively wary. In the interior aquatic insects are the chief food of downy young, adolescents, and adults. On certain lakes amphipods and molluscs are important foods. Fishes, where available, form a minor part of the diet. Seeds of aquatic plants are the main vegetable food except on Okanagan Lake where a larger amount of other plant material is consumed. On salt water, crustaceans and molluscs are first and small fishes, second in importance. The buffle-head is highly regarded as an object of beauty. In the interior it is of economic value as food but is not held in esteem on coast waters. No evidence of it eating commercially valuable fishes was obtained and its consumption of salmon eggs, noted on coast streams, does not reach significant proportions.
