Download Field Guide for the Biological Control of Weeds in the Northwest Book in PDF, ePub and Kindle
This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

Download Annotated List of the Lepidoptera of Alberta, Canada Book in PDF, ePub and Kindle
This checklist of the Lepidoptera (butterflies and moths) of Alberta lists 2367 species reported to occur in the province, as well as 138 species whose occurrence in Alberta is probable. Each species entry includes adult flight time and distribution status in the Cordilleran, Boreal, and Grasslands ecozones, as well as references to taxonomic works and to the literature and public collection sources of the records. Detailed notes on taxonomy, nomenclature, distribution, habitat, and biology are given for 1524 of the listed species. An additional section provides details on 171 species erroneously reported from Alberta in previous works. The authors hope it will be a useful resource for anyone carrying out species-level work on Lepidoptera in western Canada, or taxonomic work on Lepidoptera in general. An introductory section provides a general overview of the order Lepidoptera and the natural regions of Alberta, and the history and current state of knowledge of Alberta Lepidoptera. Each of the 63 families (and selected subfamilies) occurring in Alberta is briefly reviewed, with information on distinguishing features, general appearance, and general biology. The list is accompanied by an appendix of proposed nomenclature changes, consisting of revised status for 25 taxa raised from synonymy to species level, and new synonymy for 20 species-level and one genus-level taxa here considered to be subjective synonyms, with resultant revised synonymy for one taxon and formalization of seven new combinations.

This review focusses on invasive species affecting forestry, provincial grazing land, aquatic & wetland environments, and natural ecosystems in Alberta. Based largely on examination of the literature, major invasive species are listed under the following categories: terrestrial plants; terrestrial vertebrates; terrestrial invertebrates; aquatic organisms, including fish, plants, insects, mollusks, & protozoan parasites of fish; and plant & wildlife diseases. For each species, information is included on its status, geographic distribution, habitat, and economic & ecological impact. The review also discusses pathways & sources of new introductions and potential threats of new introductions in each species category. The final chapter presents an overall evaluation of invasive species & their impacts, pathways, and future risks. It also notes knowledge gaps.
