Hi All,
Etienne and I are enjoying an off-list discussion trying to determine why
colonies tend to build up to larger populations at higher latitudes than
they do closer to the Equator. At least comparing California to Canada, it
doesn't appear to be directly due to the longer photoperiod, once one takes
into account flight conditions.
So I'm questioning whether it is due to the amount of forage (nectar and
pollen) available -- on a sustained basis -- during colony buildup. As a
proxy, we could compare hive weight data over time.
So what I'm asking for is for those of you who have tracked hive weight
from spring through colony population peak, for a SIMPLE graph. I don't
want huge data sets to process! Just a simple graph with weight on the
y-axis, and date (weekly is fine) on the x-axis, along with your location
and latitude (or GPS coordinates). If you've added or removed supers,
please "clean up" the graph to account for that, so that it simply shows
net weight gain or loss over time.
Please email to me off list at [log in to unmask]
Thanks in advance!
