Book Description
Habitat In Canada, Limber Pine occurs typically on warm, dry sites in the lower portions of the mountains and foothills at elevations of ca. [...] With climate change, the frequency, intensity and duration of drought is projected to increase, and fire is projected to be more frequent and severe. [...] With its northern range boundary in Canada, Limber Pine is important for studies of genetic and evolutionary processes in response to climate change and the effects of introduced species, such as White Pine Blister Rust, Cronartium ribicola (Franks et al. [...] This range includes portions of the Montane, Subalpine, Foothills Parkland, and Foothills Fescue Natural Subregions of Alberta (Downing and Pettapiece 2006) and the Interior Douglas-fir, Montane Spruce, and Engelmann Spruce-Subalpine Fir biogeoclimatic zones in British Columbia (Meidinger and Pojar 1991). [...] Search Effort Most of the information on the range of Limber Pine in Canada is derived from natural resource inventories and operational monitoring in both Alberta (e.g., Holland and Coen 1982; Achuff et al.

Book Description
Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as a cause of species loss. In particular, there is little information about the ecological impacts of hyper-diverse groups such as terrestrial fungi and invertebrates. A science symposium, Ecological impacts of non-native invertebrates and fungi on terrestrial ecosystems, held in 2006, brought together scientists from the USA and Canada to review the state of knowledge in this field of work. Additional reviews were solicited following the symposium. The resulting set of review/synthesis papers and case studies represents a cross-section of work on ecological impacts of non-native terrestrial invertebrates and fungi. Although there is a strong focus on Canadian work, there is also significant presentation of work in the northern USA and Europe.
