TITLE: Sean Walker, Zoologist and Post Doctoral Fellow, University of Lethbridge
SUBJECT: #53 Mating Crickets call in Parasitic Flies
SYNOPSIS: The Canadian Zoological Society recently held its annual general meeting at the University of Lethbridge. Among the presenters was Sean Walker, a researcher at the University of Lethbridge. By studying the relationship between crickets and a tiny parasitic fly, Sean hopes to gain some insight into the evolution of mating strategies. When crickets call to attract mates, this lets the flies know their location. Larvae from the flies find their way into the crickets, and then proceed to eat them from the inside out. Some male crickets are silent. Is this an evolutionary strategy in response to the “mate vs parasite” attraction scenario?



TITLE: Ralph Cartar, Associate Professor of Biological Sciences, University of Lethbridge
SUBJECT: #53 Impact of Logging on Bumble Bees
SYNOPSIS: The effect of logging on bumble bees is one of the research projects that falls under the EMEND banner which is sponsored by the Sustainable Forest Management Network. EMEND stands for “ecosystem management emulating natural disturbance” . Biologist Ralph Cartar of the University of Lethbridge presented the results of his work on forest bumblebees to the recent Canadian Zoological Society meeting in Lethbridge. One of the things he found is that too much clearing can change the way bees relate to one another and also the way they relate to plants. This can have a significant impact on plant pollination in areas that need reforestation.



TITLE: Dr. Peter Carr, Director of the Centre of Innovative Management, Athabasca University
SUBJECT: #53 Supply Chain Study on Collaboration and Technology
SYNOPSIS: As part of his ongoing research into supply chain management, Dr. Peter Carr has undertaken another study, this one looking at collaboration between businesses in the supply chain. The survey was sponsored by the Purchasing Managers Association of Canada. The study showed that integration of new technology is fairly high, and 78% of the respondents said they wanted to use technology more in their relationships with their customers and suppliers. However, the study showed that a significant number of companies worried that they couldn’t afford to keep up with the technology. This has negative connotations for small and medium size businesses. The study also showed that a sizeable number of business leaders do not understand the full ramifications of the technology revolution, and this will lead to a shortage of skilled workers.
