Monthly, 7:30 – 9:00 PM Free for members, $5 charge at the door for non-members. Guests are welcome. No registration required.
Where: Varsity Acres Presbyterian Church, 4612 Varsity Dr. NW

Come for an evening of discovery and discussion in an informal and intimate setting! Each month we will have an interactive presentation from a different presenter.

We are looking for more CALL scientists and environmentalists –CALL members and others– to come forward to stimulate and inspire us with accounts of research pertinent in today’s world! 

Coordinators: Joe Boivin or Tom Jack

Topic: The Future of Freight and the Economy of Alberta (For Presentation PDF click Here)

With Alberta’s oil-based economy, vehicle electrification is often seen as a threat, undermining demand for gasoline and diesel fuels. However, it could also be a major opportunity for the province, especially if the vehicle’s electricity is generated from on-board hydrogen using fuel cell based drivetrains. Hydrogen fuel cell electric vehicles (HFCEV) are particularly promising as an alternative to heavy diesel engines for freight movement. The hydrogen can be made from natural gas, crude oil or biomass, and the carbon byproduct put back in the ground for permanent storage. This route to hydrogen production is a fraction of the cost of making hydrogen from splitting water with electricity so it could help to accelerate the movement to this zero-emission transportation fuel. Moreover, compared to Alberta’s current export markets for oil and gas, hydrogen production and export would return to the province, two to four times the economic benefit. A case is made for a ‘made-in-Alberta’ hydrogen economy.

Speaker: David Layzell is a Professor at the University of Calgary and Director of the Canadian Energy Systems Analysis Research (CESAR) Initiative, and cofounder of The Transition Accelerator. In CESAR and the Accelerator, he works across disciplines and sectors to identify and implement credible, compelling pathways that are capable of transforming human systems for the socio-economic and environmental benefit of Canadians. Between 2008 and 2012, he was Executive Director of the Institute for Sustainable Energy, Environment and Economy (ISEEE), a cross-faculty, graduate research and training institute at the University of Calgary. Before arriving in Calgary, Dr. Layzell was a professor at Queen’s University (Kingston) and the Executive Director of BIOCAP Canada, a research foundation focused on biological solutions to climate change. While at Queen’s, he founded a scientific instrumentation company called Qubit Systems Inc. and was elected ‘Fellow of the Royal Society of Canada’ (FRSC) for his research contributions.

Topic: Bats in Harm’s Way

Bats are the second most-diverse group of mammals, with over 1200 species found world-wide. They occupy diverse natural habitats, from tropical rainforests to the prairies and northern (boreal) forests. But they also occur in urban areas, with at least six species found in Calgary. This talk will introduce some of the fascinating biology of these hard-to-study animals: how do they locate and capture prey; as nocturnal animals, how do they make a living in the North with such short nights; do they really live up to 40 years; how do we study them and why is it important to do so? Some of the novel threats some bats face will also be discussed, such as white-nose syndrome and fatalities at wind-energy turbines.


Dr. Robert Barclay is a professor in the Department of Biological Sciences at the University of Calgary. For over 30 years, he and his students have been studying the ecology, behaviour and conservation of various mammals and birds, although the focus of most of their research is bats. Their research has involved extensive field work in various parts of Alberta, BC, Yukon, and Northwest Territories, as well as Australia, South Africa, Central America and the Caribbean. The questions they ask focus on understanding basic biology and applying that knowledge to applied issues involving forestry and forest fires, wind energy, and climate change.
