Fred Urquhart
Frederick Albert Urquhart, (December 13, 1911 – November 3, 2002) was a Canadians, Canadian zoologist and professor of zoology who studied the migration of Monarch butterfly, monarch butterflies, ''Danaus plexippus'' L. Together with his wife, Norah Roden Urquhart, he identified their migration routes, discovered that the migration spans multiple generations of butterflies, and found their wintering place in Mexico—considered "one of the greatest natural history discoveries" of the 20th-century. Early life Urquhart was born in Toronto, Canada. He attended the University of Toronto, graduating in 1935 with a degree in biology. He received the Bensley Fellowship for his graduate studies in entomology, receiving an MA in 1937 and a Ph.D. in 1940. During World War II he taught meteorology to students in the Royal Canadian Air Force. On July 21, 1945, he married Norah Roden Patterson.

Flight Of The Butterflies
''Flight of the Butterflies'' is a 2012 Canadian documentary film directed and co-written by Mike Slee for 3D IMAX, starring Megan Follows, Gordon Pinsent, and Shaun Benson. The film covers Dr. Fred Urquhart's nearly 40-year-long scientific investigation into the monarch butterfly (''Danaus plexippus''), tracking the details of what is considered one of the longest known insect migrations: the flight of the monarch butterfly from Central Mexico to the United States and Canada and back. Synopsis Monarch butterflies are a familiar sight in the United States and Canada most of the year, but disappear from most locations in winter. The documentary film weaves together factual information about the monarchs with a dramatic re-enactment of the search for the answer to the mystery of where they spend the winter. The story line follows Urquhart as a child in Canada, fascinated by the butterflies; his years of research and study, together with his wife and collaborator Norah, into their ...

IMAX
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio (approximately either 1.43:1 or 1.90:1) and steep stadium seating. Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw were the co-founders of what would be named the IMAX Corporation (founded in September 1967 as Multiscreen Corporation, Limited), and they developed the first IMAX cinema projection standards in the late 1960s and early 1970s in Canada. IMAX GT is the large format as originally conceived. It uses very large screens of and, unlike most conventional film projectors, the film runs horizontally so that the image width can be greater than the width of the film stock. It is called a 70/15 format. It is used exclusively in purpose-built theaters and dome theaters, and many installations limit themselves to a projection of high quality, short documentaries. The high costs involved in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dundas, Ontario
: ''For the county in eastern Ontario see Dundas County, Ontario. For the upper tier county, see United Counties of Stormont, Dundas and Glengarry.''

Monarch Butterfly Biosphere Reserve
The Monarch Butterfly Biosphere Reserve ( es, Reserva de Biosfera de la Mariposa Monarca) is a World Heritage Site containing most of the over-wintering sites of the eastern population of the monarch butterfly. The reserve is located in the Trans-Mexican Volcanic Belt pine-oak forests ecoregion on the border of Michoacán and State of Mexico, 100 km (62 miles), northwest of Mexico City. Millions of butterflies arrive in the reserve annually. Butterflies only inhabit a fraction of the 56,000 hectares of the reserve from October–March. The biosphere’s mission is to protect the butterfly species and its habitat. Most of the over-wintering monarchs from eastern North America are found here. Researchers discovered these areas in 1975. Presidential decrees in the 1980s and 2000 designated these still privately held areas as a federal reserve. The Reserve was declared a Biosphere Reserve in 1980 and a World Heritage Site in 2008. The reserve remains predominantly rural. Reser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
