The Hydrology Ecology And Disturbance (HEAD-1 and HEAD-2) research programs in the Western Boreal Plains of North-Central Alberta, has provided objective delineation and determination of landscape units characterized by geology and climate. From these landscape indices can be developed that provide information on the scale at which forest, wetland, and aquatic systems are linked to their surroundings and the potential response of an area to particular disturbances. In collaboration with industry, government and NGO planners and ecologists this work establishes a hydrologic risk planning process that evaluates the ecological risk and monetary costs of forest harvest on forest succession and water quality and quantity.

Total Population Size

There are few studies of life history and population growth of large dytiscid beetles in North America. We sampled populations of Dytiscus alaskanus in a eutrophic lake in north central Alberta weekly in the summers of 1982 and 1983. Like many other temperate zone dytiscids, D. alaskanus has a univoltine life cycle. Dytiscus alaskanus prefers the area at the limit of emergent vegetation in the lake and is most often associated with shoreline vegetation of cattail and sedge. Populations of adult D. alaskanus are at a peak in the late spring and decline throughout the summer. Mark–recapture experiments allowed determination of total population size and monitoring of movement patterns in the lake. Data are discussed with reference to the relatively short summer with which these beetles must cope.
