A million ways to die: The bizarre and fascinating interactions between parasitoids and their hosts

Date: 

Monday, October 26, 2015

Presenter: 

Miles Zhang, Ph.D. Candidate, Dept. of Entomology, University of Manitoba

Parasitoids are a diverse group of insects with life cycles perfect for a horror movie, as they often lay their eggs inside their host and devour their prey from within. Learn what it is to be a parasitoid, get an overview of the major groups, and see some of the interesting ways these creatures attack their hosts.

Presenter: 

Dr. Steve Ferguson, Dept. of Fisheries and Oceans (Freshwater Institute, University of Manitoba)

The Arctic ice-free season has increased in area and duration providing killer whales with an expanding arena for predation. A research group called “Orcas of the Canadian Arctic” set out to understand this change. Initially we compiled a database to document the historical occurrence, distribution, feeding ecology, and seasonality of killer whales in the region.

Presenter: 

Dr. Robert Currie, Professor and Head, Dept. of Entomology, University of Manitoba

Honey bees and some other pollinators have suffered high rates of population loss since 2006. While the problem has been extensively investigated, no single factor has been identified that can explain all instances of colony losses.

The Benefits and Challenges of Using Native Trees in the Urban Environment

Date: 

Monday, November 17, 2014

Presenter: 

Martha Barwinsky, City Forester, Urban Forestry Branch, City of Winnipeg

Urban forestry programs work to ensure canopy cover to mitigate the impacts of urbanization and to provide a liveable environment for an increasing population. But they continue to be challenged with urban sprawl that reduces natural forest cover and creates unsuitable growing conditions. A broadened global market and climate change are added challenges.

Stationarity on the Run: The New Normal for Manitoba’s Climate

How Will Climate Change Affect Manitoba? (MB Government)

Date: 

Monday, March 3, 2014

Presenter: 

Dr. Danny Blair, Associate Dean of Science, University of Winnipeg

The concept of ‘normal’ in climatology defines the range of conditions expected in the near future, based upon the recent past, with the assumption that the recent past is a reasonable approximation of the near future. Thanks to climate change, this assumption of ‘stationarity’ in the climate is no longer valid.

Presenter: 

Drs. Jane Waterman and Jim Roth, Biological Sciences, University of Manitoba

Play behaviour is common in young mammals in good condition, but adult play is rarely observed, especially in mammals that are fasting. Polar bears in northern Manitoba spend several months on land fasting while Hudson Bay is free of ice, and during this time adult male polar bears frequently play.
