and has no comments yet.
The three most widely used neonicotinoid pesticides for flowering crops pose no risk to honeybee colonies when used correctly as seed treatments, according to new studies by University of Guelph researchers.Amid mounting controversy over use of neonicotinoids (neonics) and declining bee populations, a new analysis by U of G scientists of previously unpublished studies and reports commissioned by agri-chemical companies Bayer and Syngenta – as well as published papers from the scientific literature – shows no significant ill effects on honeybee colonies from three common insecticides made by the companies.

The fish that cools off by jumping OUT of the water

and has no comments yet.
On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.In the study published today in the journal Biology Letters, the researchers describe how these fish air-chill themselves on solid ground in order to drop their body temperatures. The researchers also found that fish exposed to higher temperatures for a week tolerated warmer water better.The fish jump out of the water to escape rising temperatures, said integrative biology professor Pat Wright, senior author of the study.
