This book was released on 1996 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lodgepole pine seedlings must form associations with ectomycorrhizal fungi in order to grow normally under field conditions. The study reported in this memo quantifies the effect of two site preparations (mechanical screefing and ground chemical application) on the diversity and types of such fungi at a lodgepole pine site in the Lillooet Forest District of British Columbia. Seedling root tips were examined by microscope and richness and diversity indices were used to describe and compare the ectomycorrhizal communities from the different treatments over a three year period (1992-94).

This book was released on 2003 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry, pinegrass-dominated sites in the interior Douglas fir (IDF) zone of southern interior British Columbia are challenging to regenerate, despite ongoing improvements in nursery & silviculture practices. Using results from three separate studies, this report discusses conifer seedling survival & growth responses to silvicultural systems & site preparation treatments that were applied to relieve harsh site conditions at Fehr Mountain, Murray Creek, and Opax Mountain. To help interpret these responses, the effects of silvicultural system & site preparation treatments on seedling microenvironment are also analyzed with reference to the following factors: soil water, air temperature, soil temperature, light, nutrient availability, soil physical properties, and ectomycorrhizae.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Prior to this thesis project, our understanding of the influence of stand age and season on in vivo ectomycorrhizal communities of Sitka alder growing with Lodgepole pine within the Sub-Boreal Spruce biogeoclimatic zone was limited. The magnitude of ectomycorrhizal associates present on Sitka alder and Lodgepole pine was not known. In addition, it was of ecological interest to assess if the two host species, common to early-successional, post-harvest forest communities, were directly linked via common ectomycorrhizal fungi with reference to ecosystem interactions and possible nutrient translocation. Stemming from this general lack of knowledge, the purpose of this thesis project was to strengthen our ecological understanding of these two ectomycorrhizal communities. Two complementary methodologies were implemented in order to assess the ectomycorrhizal communities. Traditional morphological assessments offered one perspective of the mycorrhizal associates and permitted morphological description and mycobiont identification when possible, as well as richness, abundance, diversity, and evenness comparisons with respect to host, stand age, and season. It was found that mycorrhizal richness was greatest for Lodgepole pine. Seral and seasonal effects were shown to significantly impact certain Sitka alder and Lodgepole pine ectomycorrhizae. Seral and seasonal effects also significantly impacted alder ectomycorrhizal diversity and evenness assessments, however, no similar impact was observed for pine. Several possible genera of fungal symbionts were identified that may link Sitka alder and Lodgepole pine. The resolution of ectomycorrhizal taxa comprising the belowground communities were improved over morphological assessments through the use of molecular techniques, specifically PCR-RFLP analyses, the second technique applied. Molecular datasets further confirmed some morpholog_ical assessments and defined morphological descriptions allowing for identification of some mycobionts mostly to the genus level, but also to the species level, as well as determining inter- and intraspecific variation of the int!'lrnal transcribed spacer region of rONA within certain morphotypes. Two mycobiont genera (Cortinarius and Lactarius) were identified on both hosts which suggest the possibility of direct mycorrhizal linkage. In this study, molecular diversity assessments, when used in conjunction with defined morphological techniques (such as morphotyping), offered a complementary synopsis of the diversity and dynamics of ectomycorrhizal communities. Taxa were distinguished to a finer taxonomic level and could be identified using PCR-RFLP analysis while the abundance of ectomycorrhizal morphotypes was best described using morphological techniques. The research indicated that stand age and season can significantly influence alder and pine ectomycorrhizae."--Pages ii-iii.

Available in PDF, EPUB and Kindle. Book excerpt: With sixty descriptive maps and accompanying text, The Biodiversity Atlas of British Columbia provides a broad overview of the province?s range of terrestrial and freshwater biological diversity. Bringing together data from numerous sources summarized in map form, the Atlas provides a window to B.C.?s diverse ecosystems, the species that live in them, and the elements of British Columbia?s biodiversity that make it globally significant. The Atlas also presents a visual perspective of a number of human-induced threats, including climate change, affecting biodiversity in B.C. today. The Atlas is designed to serve as a companion document to Taking Nature?s Pulse: The Status of Biodiversity in British Columbia ? a comprehensive scientific assessment of biodiversity in the province. Both the Atlas and Taking Nature?s Pulse are projects of Biodiversity BC, a partnership of conservation groups and government agencies.
