Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

Monitoring insect diversity and parasitism levels in alfalfa seed production fields in western Canada
DownloadFall 2022
Alfalfa, Medicago sativa (L.) (Fabales: Fabaceae), is an excellent source of high protein feed for livestock. Canada is the second largest producer of alfalfa seed (4.2 M kg/year) in the world, with the vast majority of production concentrated in the province of Alberta. The productivity of these...

Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Biodiversity loss endangers ecosystem services and is considered as a global change that may generate unacceptable environmental consequences on the Earth system. Global biodiversity observations are needed to provide a deep understanding of the biodiversity - ecosystem services relationship and...

Multiple novel and rapidly changing environmental factors (i.e. anthropogenic stressors) are increasingly affecting ecological communities, and their functional roles in ecosystems. Consequently, freshwater biodiversity has declined worldwide; however, the functional impacts of this loss should...

Bees are a key component of terrestrial ecosystems and provide valuable ecosystem services to both natural and agricultural landscapes. It estimated that 87.5% of native plants benefit from pollination, including 1/3 of global food crops. Additionally, pollination by bees provides maximized...

Prairie wetlands provide many important ecosystem services including supporting biodiversity, improving water quality, preventing erosion, recharging groundwater, and attenuating floods. However, more than half of prairie wetlands in North America have been lost, primarily due to drainage for...

After decades of recent fire exclusion in southern Alberta, Canada, forests are progressively aging and landscape mosaics are departing from their historical conditions. A large-scale fire history study spanning three natural subregions: Subalpine, Montane and Upper Foothills, was undertaken to...

This research compared the variability/diversity of spectral information captured with spectrometers at the airborne, field, and leaf level to tree species diversity. Airborne measurements were made over the North Saskatchewan River Valley while field and leaf measurements were done with...

The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...
