Towards species specific management of invasive hawkweeds in British Columbia: Quantifying distributions, modeling potential invasion extent, and investigating genetic-morphometric congruence

The species of European hawkweeds present in British Columbia are aggressive and ecologically detrimental invaders of meadows, parks, agricultural lands and rangelands. Left unmanaged, these species could cost the province of British Columbia upwards of $60 million in economic losses by 2020. The Ministry of Forests, Lands and Natural Resource Operations (MoFLNRO) is responsible for addressing invasive plant species on Crown land.

Canadian Bioscience Education Through DNA Barcoding

A Canadian scientific innovation known as DNA barcoding is advancing species identification and discovery through the analysis of short, standard gene regions. This has led to the widespread use of DNA barcoding as a tool for species identification in a diverse array of practical applications, from ecological monitoring to food fraud.

Net ecosystem exchange of carbon dioxide over agricultural fields near Lacombe, Alberta

Agriculture and Agri-Food Canada (AAFC) and Campbell Scientific Canada Corp. (CSC) have been operating an “eddy covariance” meteorological tower near Lacombe, Alberta that measures the flux of carbon dioxide (CO2) between agricultural fields and the atmosphere. This tower provides high frequency data that is used to assess plant growth and decomposition across large fields which is critical for understanding local crop viability and the role of Canadian agriculture in the global carbon cycle.

Assessing and improving the analysis of migration count data for population monitoring

Counts of birds passing a geographic location during migration to or from their breeding grounds are often used to estimate long-term population change. However, birds often stop at count sites for several days to fatten for their next migratory flight, affecting probability of detection. The migratory path followed might also vary among years. The influence of such factors on population estimates are unknown.
