Investigating the effects of current forestry management practices on the quality and productivity of black huckleberry (Vaccinium membranaceum) in southeastern British Columbia

Black huckleberry (Vaccinium membranaceum) is an important wild food plant for people and wildlife in the East Kootenays of British Columbia.  Over the past 50 years changes in forestry practices, and the intensity of timber harvesting have changed the forest and the habitat where black huckleberries grow.  This research project will employ scientific and ethnographic methods to investigate the effects that clear-cutting and logging are having on the abundance, productivity and harvesting of black huckleberry in the East Kootenays.  Developing an understanding of how huckleberries

Whitebark Pine and Grizzly Bear Research and Recovery in Southwest BC

Whitebark pine is an important high elevation species in BC’s coastal mountains, but it is vulnerable to extinction due to threats such as pest outbreaks and climate change. The species is therefore in dire need of restoration and research to both sustain future populations, and improve scientific knowledge of its ecological functions. The internship involves assisting in an enhancement and research program being conducted by Keefer Ecological Services Ltd. and the Lillooet Tribal Council.

Improving Query Performance on Database Free-Text and Semi-Structured Text Columns

The project deals with the better indexing of text fields in the database. It explores an idea of on-line maintenance of an inverted index, which is built for the tokens of the text content in the database. The on-line update of such an index is currently considered impractical. We try to overcome this inverted index update bottleneck with the use of B-tree data structure and the specially designed in-memory buffer. In case of success, this on-line indexing will highly improve the performance of user queries on database text fields.
