RE: Insects at K/T boundary

[Roy Plotnick <plotnick@xxxxxxx>]

Darryl raises an important I've often wondered about.  Time of year should
be quite important; an "impact winter" could have quite different effects if
it occurs when it is already winter in a particular hemisphere (and
organisms are already acclimated) then if it occurs in the height of summer.
And again - lets not forget that there are both northern and southern
hemispheres whose seasons are out-of-phase and equatorial zones that have
little seasonality! -Roy
