Effects of leaf litter and environment on bryophytes in boreal forests of Alaska
Bryophytes dominate the forest floor, regulate soil microclimate, and participate in the carbon (C) and nitrogen (N) cycles in coniferous boreal forests, while deciduous stands support a lower bryophyte abundance. Recent ...
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 ...
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 ...
Tree Ring Responses to Climate: Drought Stress Signals Decreased Resilience of Northern Boreal Forests
Unprecedented rates of climate change have increased forest stress and mortality worldwide. Previous research in the boreal forest has largely documented negative growth responses to climate in forest species and habitats ...
