In accordance with the Species at Risk Act (SARA), the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) is nationally responsible for assessing wildlife species considered to be at risk of extinction. A parliamentary review of SARA provides impetus for an up-to-date summary of recent assessments (2006–2008) and a spatiotemporal analysis of the status of Canada's largest vertebrate group of species at risk, fishes. From April 1978 through December 2008, COSEWIC had assessed 13 wildlife species as extinct and 564 at some level of risk (extirpated, endangered, threatened, special concern). Among these 577 assessments, 112 are for fishes (76% freshwater and diadromous; 24% marine). Slightly more than one-quarter (27%) of Canada's 205 freshwater and diadromous species of fishes, many of which are in southwestern Ontario and southeastern Quebec, have been assessed as being at risk throughout all or parts of their ranges. The percentage of Canadian freshwater and diadromous fish species assessed by COSEWIC as endangered or threatened (16%) is similar to the percentage of freshwater and diadromous fishes in the US that have been listed under the Endangered Species Act (12%). The proportion of wholly freshwater fishes assessed by COSEWIC that have been added to SARA's legal schedule is somewhat lower than that of other taxa. However, whereas the US listed its first marine fish in 2005, the Canadian government has to date not accepted COSEWIC's advice to list an endangered or threatened marine fish since the proclamation of SARA in 2003.

Lesson Drawing

Abstract. Although the US and Canada share ecosystems, with many species ranging freely across the border, the two countries have taken very different approaches to protecting endangered species. The US Endangered Species Act, adopted in 1973, relies primarily on regulation, thus imposing the costs of protecting biodiversity on the private sector. In contrast, Canada's Species at Risk Act, adopted in 2002, relies primarily on public expenditures to support stewardship programs. We argue that this difference is best explained by negative lesson drawing from the US experience. In particular, awareness of the costs of species protection in the US led Canadian business to present stronger opposition to regulation than had their American counterparts decades earlier. We use the case of the Canadian Species at Risk Act to theorize about conditions under which negative lesson drawing is likely to be most influential.Résumé. Bien que les États-Unis et le Canada partagent les mêmes écosystèmes, les deux pays ont adopté des approches très différentes en matière de protection des espèces en péril. La Loi américaine sur les espèces en péril (US Endangered Species Act), adoptée en 1973, porte essentiellement sur la régulation, et de ce fait impose les coûts de la protection de la biodiversité au secteur privé. En revanche, la Loi canadienne sur les espèces en péril, adoptée en 2002, fait principalement retomber les coûts des programmes de gestion au secteur public. Nous démontrons que cette différence s'explique principalement par le rôle des leçons négatives apprises de l'expérience des États-Unis. La prise de conscience des coûts liés à la protection des espèces en péril aux États-Unis a notamment amené les milieux d'affaires canadiens à présenter une plus forte opposition à la régulation que leurs homologues américains l'avaient fait des années plus tôt. En s'appuyant sur le cas de la Loi canadienne sur les espèces en péril, nous visons à théoriser les conditions selon lesquelles l'acquisition de connaissance par leçons négatives (“ negative lesson drawing ”) est susceptible d'être le plus concluant.

In Canada, the grey fox (Urocyon cinereoargenteus) is found with certainty in Ontario and Manitoba, but has also been sighted in other provinces. Interestingly, there is little Canadian research on the grey fox, despite its status as “threatened” on both the Ontario Species at Risk list and on the Canadian Species at Risk Act. Possible reasons that the grey fox has not received as much attention as other at-risk species in Canada include its lack of economic value and its high abundance in the United States (US). It is believed that the grey fox was once as widespread as the red fox (Vulpes Vulpes) in Southern Ontario, but today that is no longer the case. It is currently believed that less than 250 individuals are found in Canada and the fate of their population is unknown. This change in population abundance shows the importance of gaining more information on the grey fox’s current distribution in Canada. Within the US, the primary threat to this species is excessive hunting; while in Canada, by-catch, deforestation, and road mortality represent greater dangers. The focus of this presentation will be to summarize current knowledge on Canadian populations of the grey fox with some reference to populations in the US in order to highlight the importance of this trans-boundary species within Canadian ecosystems. I will provide recommendations to both the Federal Government of Ontario and the Municipality of Peelee Island, while outlining possible conservation solutions for the population decline of the grey fox in Canada.

Model Programs

At the present time there is a need for a new generation of programs to address the needs of ‘at risk’ children and families. This is an issue that is exercising the minds of service planners in both government and non-government community service organisations. This need arises from the fact that many existing programs have yet to be rigorously evaluated and are of questionable effectiveness. This lack of evidence of effectiveness does not sit well in the current climate of accountability. It also runs contrary to the increasingly strident calls for evidence based practice.Many new programs arrive in Australia from the US as this country is often the source of program innovation as illustrated by the importation in the 1980s and 1990s of family preservation and family reunification programs. In the US, promotion of ‘model programs' has taken another step and a systematic effort at program replication is now in evidence. The question is, how might model programs from overseas be successfully replicated in Australia? And what is required, if anything, to replicate these models effectively taking account of our different cultural traditions?

scholarly journals Modeled replacement of traditional soybean and canola oil with high-oleic varieties increases monounsaturated fatty acid and reduces both saturated fatty acid and polyunsaturated fatty acid intake in the US adult population

ABSTRACT BACKGROUND High-oleic (HO) seed oils are being introduced as replacements for trans fatty acid (TFA)–containing fats and oils. Negative health effects associated with TFAs led to their removal from the US Generally Recognized As Safe list. HO oils formulated for use in food production may result in changes in fatty acid intake at population levels. Objectives The purposes of this study were to 1) identify major food sources of soybean oil (SO) and canola oil (CO), 2) estimate effects of replacing SO and CO with HO varieties on fatty acid intake overall and by age and sex strata, and 3) compare predicted intakes with the Dietary Reference Intakes and Adequate Intakes (AIs) for the essential fatty acids (EFAs) α-linolenic acid (ALA) and linoleic acid (LA). Design Food and nutrient intakes from NHANES waves 2007–2008, 2009–2010, 2011–2012, and 2013–2014 in 21,029 individuals aged ≥20 y were used to model dietary changes. We estimated the intake of fatty acid with the replacement of HO-SO and HO-CO for commodity SO and CO at 10%, 25%, and 50% and evaluated the potential for meeting the AI at these levels. RESULTS Each modeling scenario decreased saturated fatty acids (SFAs), although intakes remained greater than recommended for all age and sex groups. Models of all levels increased the intake of total monounsaturated fatty acids (MUFAs), especially oleic acid, and decreased the intake of total polyunsaturated fatty acids (PUFAs), particularly LA and ALA. Replacement of traditional with HO oils at 25–50% places specific adult age and sex groups at risk of not meeting the AI for LA and ALA. Conclusions The replacement of traditional oils with HO varieties will increase MUFA intake and reduce both SFA and PUFA intakes, including EFAs, and may place specific age and sex groups at risk of inadequate LA and ALA intake.
