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 ...
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 ...
Comparison of the bacteria within ticks from allopatric and sympatric populations of Dermacentor andersoni and Dermacentor variabilis near their northern distributional limits in Canada
Understanding the ecology and epidemiology of tick-borne diseases requires detailed knowledge of the complex interactions among the tick vector, the microorganisms they carry and the vertebrate hosts used by ticks, as well ...
Analysis of Arabidopsis AIR12 and Brassica carinata CIL1 in root development and response to abiotic stress
The development of plants challenged by environmental stress alters plant architecture through several pathways, including those involving plant hormone responses and reactive oxygen species (ROS) production. Auxin, a ...
Role of FtsA in cell division in Neisseria gonorrhoeae
Bacterial cell division is an essential process, which is initiated by forming the Z-ring as a cytoskeletal scaffold at the midcell site, followed by the recruitment of a series of divisome proteins. In Escherichia coli ...
Characterization of novel pathways in the phosphorus cycle of lakes
Phosphorus (P) is a limiting nutrient regulating productivity in both freshwater and marine ecosystems. A full knowledge of the sources and pathways of the P cycle is essential for understanding aquatic ecosystem function ...
Sex, friends, and disease: social ecology of elk (Cervus elaphus) with implications for pathogen transmission
Many mammals are social. The most basic social behaviour is when the actions of one conspecific are directed toward another, what we call the ‘dyadic interaction’. Both intrinsic and extrinsic factors may affect an ...
