next webinar will have a slightly different format than those you’ve seen in
the past. Get comfortable because it will be <B>two hours long</B>. The first
hour will focus on overwintering bees. We will discuss location (urban,
rural), pests and predators, feeding, temperature extremes, as well as much
more. This discussion features Michael Palmer, a commercial beekeeper in
northern Vermont, to help us with the northern climates, and Harry Fulton,
retired State Apiarist from Mississippi, who will bring the southern
perspective. To fill in the bits and pieces, Kim Flottum, editor of Bee
Culture Magazine will be joining us. That is the first hour. The second hour
will be a panel discussion of sorts on all things beekeeping. We have had
numerous requests for just an Q;& A session. With this panel, there is not
a question they won't be able to answer.</SPAN></SPAN></P>

Internal Clocks</FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>Honey bees removed
from their usual roles in the hive quickly and drastically changed their
biological rhythms, according to a study in the Sept. 15 issue of <I>The
Journal of Neuroscience</I>. The changes were evident in both the bees'
behavior and in their internal clocks. These findings indicate that social
environment has a significant effect on the physiology and behavior of
animals. In people, disturbances to the biological clock are known to cause
problems for shift workers and new parents and for contributing to mood
disorders. </FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>Circadian rhythm, the
body's "internal clock," regulates daily functions. A few "clock genes"
control many actions, including the time of sleeping, eating and drinking,
temperature regulation, and hormone fluctuations. However, exactly how that
clock is affected by — and affects — social interactions with other animals is
unknown. </FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>Senior author Guy
Bloch, PhD, and his colleagues from The Hebrew University of Jerusalem,
Israel, chose to study bees in part because of their complex social
environment. One role in bee society is the "nurse": bees that are busy at all
times caring for larvae. This continuous activity is different from other bees
and animals, whose levels rise and fall throughout the day. </FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>Bloch and his team
thought that changing the nurse bees' social environment might alter their
activity levels, so they separated them from their larvae. The researchers
found that the bees' cellular rhythms and behavior completely changed,
matching a more typical circadian cycle.</FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>"Our findings show
that circadian rhythms of honey bees are altered by signals from the brood
that are transferred by close or direct contact," Bloch said. "This
flexibility in the bees' clock is striking, given that humans and most other
animals studied cannot sustain long periods of around-the-clock activity
without deterioration in performance and an increase in
disease."</FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>The results suggest
that the bees' internal clocks were shaped by certain social cues. Jürgen
Tautz, PhD, of the Julius-Maximilians Universität Würzburg in Germany, an
expert in honey bee biology who was unaffiliated with the study, said it is a
wonderful example of the tightly regulated interactions between genes and
behavior in a bee colony. "The presence or absence of larvae switched the
genes 'on' or 'off,' which guaranteed the adaptive behavior of the bees,"
Tautz said. </FONT></SPAN></P>
<P>
<P style="MARGIN: 0in 0in 10pt; LINE-HEIGHT: normal"><SPAN style="FONT-SIZE: 10pt; COLOR: black"><FONT face=Calibri>Because bees and
mammals' circadian clocks are similarly organized, the question is whether the
clocks of other animals also strongly depend on their social environments. The
next step is to find just how social exchanges influence gene expressions.
Further research into this question may have implications for individuals who
suffer from disturbances in their behavioral, sleeping, and waking cycles.
Research into how these rhythms may be altered and even stabilized might
identify new treatment options.</FONT></SPAN></P>
