A parasitic basidiomycete, referred to Corticium anceps (Bres. & Syd.) Gregor, has been found to be common on a large number of hosts in the Timagami Forest Reserve, Ont. The same species is known to occur also in Quebec and in four of the northern United States. The fungus is transferred to the genus Ceratobasidium. The history of our knowledge of this parasite is reviewed, and a description and illustration of the fungus is provided as well as a discussion of the symptomology with illustrations of the effect on several hosts. A full list of the hosts on which the fungus has so far been found in North America, with the provinces and states in which collections have been made, is given in tabular form. The incompleteness of our knowledge with reference to host specialization, infection, and colonization of the host, and overwintering of the fungus is discussed and suggestions made for future work.

National Perspective

This paper's objective is to bring forth some elements which confirm the following hypothesis : Canada is consigned to continentalism, namely to economic and cultural integration with the United States though this fact is shrouded in a Canadian nationalism of sorts. The continentalist mentality is rooted in the history of British North America, inhabited mostly by refugees from America who have remained inherently "Yankees" in spite of their anti-americanism. The Confederation itself is based on a sort of complicity with the United States. More recently there were talks of a "North American nationality", and continentalism both cultural and economic has come to be seen as a 'force of nature" which the governments, at the most, put into a chanelling process. Still, it is possible for Canadian nationalism to exist provided it does not go beyond the threshold whence it would run headlong into the continental mentality. Canada has defined itself through an international or non-national perspective far too long for today's nationalism not to remain weak and poorly established. But the Americans whose "manifest destiny" has succeeded in spreading over Canada without even their having tried to hoist their flag there find it to their advantage to maintain some form of Canadian sovereignty. Canada as a "friendly nation" can be of use to Washington. That is why there are almost as many advocates for Canada's independence in the United States as there are north of the border. Canadian nationalism can thus further the interests of some Canadian elites without seriously prejudicing continental integration which can very well afford not to be set up into formalized structures.

The native balsam fir sawfly, Neodiprion abietis (Harris) (Hymenoptera: Diprionidae), occurs throughout Canada, Alaska, and the northern United States of America (Rose et al. 1994; Drooz 1985). This sawfly was originally described as Lophyrus abietis (Hymenoptera: Diprionidae) (Harris 1841), then transferred to the genus Diprion (Hymenoptera: Diprionidae) (MacGillivray 1916). Rohwer (1918) established the genus Neodiprion for Nearctic species of the genera Lophyrus and Diprion. Based on differences in size, color, and female genitalic characters between adults reared from the genera Abies, Picea, Pseudotsuga, and Tsuga (Pinaceae), Ross (1955) considered N. abietis as a complex. After a thorough morphological and physiological study, Knerer and Atwood (1972) concluded that there were five strains of N. abietis in North America: one western and four eastern.

The importance of decisions regarding the allocation of jurisdiction over Indigenous affairs in federal states can only be understood well when studied transnationally and comparatively. Historians of Canada appear never to have considered the significance of the fact that the British North America Act (1867) gave the Canadian federal government exclusive jurisdiction over Indian affairs, even though that stipulation is unique among the constitutional documents of comparable federal states (the United States and Australia). This article explains that the constitutional provisions in Canada, the United States, and Australia are a product of the previous history of indigenous-state relations in each location, but also profoundly affected subsequent developments in each of those countries. Despite stark differences, the similar and parallel developments also hint at trends that influenced all three countries.

GYRINUS (GYRINULUS) CAVATUS SP.NOV. FROM NORTH AMERICA DESCRIBED AND COMPARED WITH GYRINUS (GYRINULUS) MINUTUS FABRICIUS (COLEOPTERA: GYRINIDAE)

AbstractGyrinus cavatus sp.nov. (type locality: Floral, Saskatchewan, Canada), from across Canada, is compared with G. minutus Fabricius. The two species are broadly sympatric in the northern boreal and transition forests, but G. cavatus is more abundant southward into the northern United States. Therefore, the subgenus Gyrinulus Zaitsev is not monobasic, but has three species in North America, including G. rockinghamensis LeConte.

Databases of accumulated paleoecological and archaeological records provide a means for large-scale syntheses of environmental and cultural histories. We describe the current status of the Canadian Archaeological Radiocarbon Database (CARD), a searchable collection of more than 36,000 14C dates from archaeological and paleontological sites from across North America. CARD, built by the late Dr Richard Morlan of the Canadian Museum of Civilization, consists of uncalibrated 14C data as well as information about the material dated, the cultural association of the date (e.g. Paleoindian, Archaic, Woodland), and its geographic location. The database can be used to study questions relating to prehistoric demography, migrations, human vulnerability to environmental change, and human impact on the landscape, but biases relating to sampling intensity and taphonomy must first be accounted for. Currently, Canada and the northern United States are well represented in the database, while the southern United States is underrepresented. The frequency of 14C dates associated with archaeological sites increases through time from 15,000 cal yr BP until European contact, which likely reflects, among other factors, both the destruction of older cultural carbon due to erosion and dissolution and increasing population numbers through time. An exploratory analysis of the dates reveals their distribution in both time and space, and suggests that the database is sufficiently complete to enable quantitative analysis of general demographic trends.

A growing subset of hometown and place-based foundations in the United States have adopted an embedded philanthropic approach, in which funders “dig in” and “dig deeper” into the life of communities. Embedded philanthropy and embedded funders may change the landscape of community-building efforts in significant ways. This article discusses the history of U.S. foundations, their involvement in community development, and the emergence of comprehensive community initiatives. This entry also describes the distinction between embedded funding approaches and other conventional efforts. These include the use of a “bottom up” approach to social change, a focus on helping communities to build capacity, and the building of community assets. Case studies of select embedded foundation efforts will be presented to illustrate current methods, challenges, and implications for future work. This entry will also discuss a few of the new roles foundations play in order to achieve their objectives. As this approach continues to evolve and more evaluations take place, greater understanding will develop regarding the way forward for foundations in the United States.
