Sable and Two-Rock Lake Fish-Out
chercheur principal: Armstrong, Allison
Année(s) de permis: 2002 2001
Résumé: The objective of the fish-out is to provide scientifically defensible data to: (1) quantify fish production, fish habitat and productivity of the intermediate trophic levels (primary and secondary producers); (2) establish linkages between fish habitat and fish productivity in Sable and Two-Rock Lakes; (3) establish a reference database through which comparisons among lakes can be conducted; and (...


Temporal Variability of Stable Carbon and Nitrogen within the Food Webs of Wood Buffalo National Park
chercheur principal: Sotiropoulos, Maria
Année(s) de permis: 2000
Résumé: The extensive wetland complex in Wood Buffalo National Park (WBNP) is composed of a mosaic of shallow ponds that are unique in Canada. They are also the nesting grounds of the last migratory population of Whooping Cranes. Water, organic matter, aquatic plants and small aquatic life forms will be sampled from ponds just outside the nesting area and 0.5 km from the highway. The research team will ...
