Re: overwintering daphnia
I chuckle when you guys from florida talk about overwintering something
outside. Your greatest fear is the temperature getting near or slightly below
freezing. When We up North talk about overwintering something outside it means
that it may be subjected to temperatures not only below freezing but in single
numbers for days at a time. I am in northern Ohio and I know there Are many of
you out there that have more severe winters than we do here in Ohio.
I wonder if anyone out there has kept a Daphnia culture outside in a northern
winter and then had it come back to life in the summer months.
