Description

This paper describes the pattern of genetic variation for growth potential among white spruce provenances in Alberta. It uses total height and diameter at breast height at 27-years from seed to identify provenance differences in relation to latitude and elevation of weed origin. Latitude and elevation are the main variables that adequately describe climatic variability in Alberta.

This report describes results from measurements of 15 year height and diameter at breast height made on a series of provenance trials comprised of 23 Alberta populations planted on 0 test sites... More ≫

Description

This report describes results from measurements of 15 year height and diameter at breast height made on a series of provenance trials comprised of 23 Alberta populations planted on 0 test sites across the province. Although currently the age of these trials ranges from 19 to 24, only 15 year data for height and diameter are available for all trials.

A comprehensive set of interpolated climate data for Alberta

Description

We present an easily accessible database of interpolated climate data for Alberta that includes monthly, annual, decadal and 30-year normal climate data for the last 106 years (1901-2006), as well... More ≫

Description

We present an easily accessible database of interpolated climate data for Alberta that includes monthly, annual, decadal and 30-year normal climate data for the last 106 years (1901-2006), as well as climate change projections for the 21st century from 23 general circulation models. The database builds on the Alberta Climate Model and a set of five future projections that are recommended and widely used by Alberta government agencies. We added 15,000 historical and projected climate surfaces that include variables relevant for biological research and infrastructure planning, such as growing and chilling degree days, heating and cooling degree days, growing season length descriptors, frost free days and extreme minimum temperature. The database can be queried through a provided software package ClimateAB. A representative subset of these climate surfaces has been thoroughly checked against observed weather station data. We report error estimate for historical climate data and discuss...
