ITEM:2

TITLE: Dr. Samantha Song, Research Scientist, Alberta Research Council
SUBJECT: #23 Mixedwood Biodiversity Project
SYNOPSIS: Dr. Samantha Song of the Alberta Research Council is leading the research on forest songbirds. She is looking at how birds use various age classes of forest pre and post harvest. One new technique which is helpful in determining which species are nesting in an area is the "mobbing call". A recorded tape of chickadees mobbing a predator is played for five minutes. This is very successful at bringing in all kinds of birds, from pine siskins to crows, because everyone is curious about what might be happening

ITEM:3

TITLE: Dr. Martin Paetz, Fish Biologist and retired Director of Fisheries for the Province of Alberta
SUBJECT: #23 Dr. R.B. Miller and the Gorge Creek Biological Research Station
SYNOPSIS: The first biological research station in Alberta was established by Dr. R.B. Miller at Gorge Creek in the Eastern Slopes in 1950. Miller replaced Dr. William Rowan after his untimely death, and became the chairman of the zoology department at the University of Alberta. Martin Paetz was a student of R.B. Miller, and worked closely with him on fish studies at Gorge Creek. Miller was particularly influential in changing government policies on the use of hatchery fish to stock streams. His research showed that the hatchery fish did not survive well for a variety of reasons. Miller was also influential in convincing the government of the need to hire staff biologists, of which Martin Paetz became the first one for fisheries.
