* I'm rereading Hynes' 'Ecology of Running Waters,' and he makes just
this point about floods - stream beds and their biota are strongly
shaped by rare events of extreme high water. I was thinking just this
about droughts this afternoon in our Manitoba Maple thicket, looking
at the plants that had and hadn't been killed by the summer's drought.
