Opening the event addressing global waste problems, Dr. William McIlveen gave an interesting look into how humans and their environmental impacts evolved over time. Loss of habitat and species extinction relayed a sense of urgency to take collective action regarding waste reduction.
Although a pretty grim picture was painted, he ended on a positive note. There is something you can do about it.
A more detailed account of the event can be found in this month's newsletter. Continue Reading ››
"They're not used to looking for a car or a truck coming", says terrestrial ecologist.
"If you happen to see a snowy owl, that's just good fortune", says Bruce Mackenzie of the Hamilton Naturalists' Club.
What appears to be an earlier than usual arrival from their Arctic breeding ground, is not good fortune for the owl.
"Snowy owls arrive in Hamilton area, but bad fortune is waiting"

On February 27, 2014, the International Joint Commission [I.J.C., 2014] released a report on the most recent algae bloom problem in Lake Erie. That report had much in common with a similar problem that existed in the Great Lakes about 50 years before. That problem was the association between phosphorus loading in the water column and the subsequent growth of algae, most conspicuously Cladophora glomerata, though blue green bacteria and other species constitute additional problems.

There is little doubt that the winter solstice of 2013 will be one to remember for a long time to come. The situation was certainly not unprecedented for some freezing rain occurs in most winters. And the amount of rain that fell was less than that that which happened in the great ice storm of 1998 in Ontario. Yet the extent of area that was impacted and the number of people affected in 2013 might well be much … Continue Reading ››
Earlier this Spring on two successive days, I was driving along our gravel road and noticed a ‘dust devil’ at the same location each time. I am sure that everyone has seen such things at some point in their lives. Seeing one is not at all unusual but noting two in the manner that they occurred prompted me to prepare this little note.
The conditions that must exist to form the dust devils will likely occur many times but they remain … Continue Reading ››
So far, the year 2012 has seen some disruptions in normal weather patterns. In March, we experienced some rather warm days that caused many wild flowers to appear early, foliage on trees and shrubs to emerge early, and for amphibians to start breeding early as well. This was followed by a relatively cool April. Then in June and July there were days with high temperatures and dry conditions. This report examines some of the impacts of those weather conditions on … Continue Reading ››
Recently, one of the items covered by the news media was the change in distribution of various species owing to climate change. There are other causes for expansions of populations other than climate shifts but this discussion is limited to the global warming phenomenon. The media accounts included the recent appearance of fish species in the ocean much further north than where they normally occur. One species that was mentioned that has relevance to our own area was the Giant … Continue Reading ››
