title: Genotypic variation among Gammarus fasciatus (Crustacea: Amphipoda) from the Great Lakes - St. Lawrence River: implications for the conservation of widespread freshwater invertebrates

authors: Hogg, Ian D.

abstract: We examined the population genetic structure of the amphipod Gammarus fasciatus (Crustacea: Amphipoda) over two years from a total of 11 sites within the Great Lakes - St. Lawrence River system using allozyme electrophoresis. In 1995, we examined differences within the St. Lawrence River (Cornwall to Quebec City), and in 1996, we focused on larger scale, whole-system differences from Lake Superior to Lake Champlain. We found very low levels of genetic differentiation among sites (Wright's FST < 0.03). This was not unexpected for an active disperser in a relatively contiguous system. However, we also found low levels of genetic variability within sites (Hobs = 0.07- 0.15), a result that was not anticipated. We surveyed the available literature on gammarid and other amphipods and found that limited genetic variability is characteristic of continuously distributed taxa, contrary to the expectations of current conservation theory. This is potentially of concern, especially in light of recently reported declines of G. fasciatus at several locations within the St. Lawrence River and Great Lakes. Given the importance of species such as G. fasciatus in aquatic food webs, further work is clearly needed on the consequences of population genetic structure to species' responses to novel environmental changes (e.g., exotic species introductions).

title: Facilitating and integrating learning within sport studies cooperative education: Exploring the pedagogies employed by students, academics and workplace supervisors

authors: Martin, Andrew

subjects: work integrated learning

abstract: Using an interpretative case study methodology, the pedagogical approaches used to facilitate and integrate student learning in cooperative education programmes in sport studies were investigated. This research drew from two New Zealand university cohorts and involved six focus group interviews. Findings suggested there were limited direct explicit attempts to integrate on- and off-campus learning. Integration was implicitly or indirectly fostered, principally by reflection through assessments (e.g., journals, reports), and primarily consisted of reflection-on-action (Schön, 1991) after the learning activities. Significantly, the integration of learning also consisted of reflection on personal growth, rather than critical reflection on theory or organisational practice.
