Tundra vegetation recovery on 30 year-old seeded and unseeded drilling mud sumps in the Mackenzie River Delta region, NWT
Oil and gas exploration conducted in the 1970s left behind a legacy of abandoned well sites in the Mackenzie Delta region of northern Canada, including several in the Kendall Island Migratory Bird Sanctuary and surrounding ...
Ecological responses to altered fire frequency in treeline forests of the North Yukon, Canada
Climate change is expected to alter patterns of disturbance, which in turn may drive future ecosystem change. This interaction may be particularly important in sub-arctic regions due to rapid climate change and frequent ...
BIOLOGICAL TOOLS FOR WATER SECURITY IN THE NORTHERN GREAT PLAINS
Rivers and streams are a critical component of Northern Great Plains ecosystems and an extremely valuable source of surface water. Despite their importance, these waterbodies have traditionally received much less scientific ...
Social learning of predation risk and safety: fish behaviour as a model for fear recovery
The abstract of this item is unavailable due to an embargo.
Reproductive ecology of temperate-nesting waterfowl : temporal and spatial patterns of investment and success in lesser scaup (Aythya affinis) (AYTHYA AFFINIS)
Ecologists and conservation biologists alike aim to understand factors determining the abundance and distribution of free-living organisms and to pinpoint why free-ranging animal populations decline. My broad goals were ...
Relationships between plant productivity and soil conditions in alpine tundra of southern Yukon Territory, Canada
Climate change is predicted to significantly alter ecosystem functioning and species distributions across the globe. Arctic and alpine areas are experiencing a faster rate of temperature increase as compared to other ...
FACTORS INFLUENCING BODY CONDITION AND ARRIVAL PHENOLOGY OF NEOTROPICAL MIGRANTS AT A NORTHERN SPRING STOPOVER SITE
Assessing the effect of winter habitat quality and environmental conditions on the fitness of migratory birds is important to understand factors that regulate migratory bird populations throughout the annual cycle. I ...
Collision avoidance behaviour in a pair of flying locusts (Locusta migratoria L.)
Migratory locusts; Locusta migratoria L. flying in a swarm would encounter spatiotemporally complex visual cues such as translating, receding and looming stimuli, produced by self-motion as well as object motion in the ...
Vegetation associations along disturbance gradients on the sand dunes of Sable Island, Nova Scotia.
Sable Island, Nova Scotia, is a dynamic dune ecosystem that is composed of plant communities exposed to varying levels of disturbance. The island is exposed to extreme weather events throughout the year, and this plays an ...
MAMMALIAN HERBIVORY SLOWS THE GROWTH OF BROADLEAF SPECIES IN POST-FIRE, EARLY SUCCESSIONAL FORESTS IN INTERIOR ALASKA
Boreal forest vegetation is likely to change in response to warming and associated changes in disturbance regimes. Recently, high severity fires have caused a shift from pre-fire mature black spruce stands to early assemblages ...
