&gt; Hi everyone,<br>
&gt;<br>
&gt; We have had some discussion about the decline of insects in Nova Scoti=
a. A study published in the online scientific journal PLOS ONE indicates th=
at there has been a dramatic decline in average airborne insect biomass of =
76% (up to 82% in midsummer) in just 27 years for 63 protected nature areas=
 in Germany.<br>
&gt;<br>
&gt; Their results demonstrate that recently reported declines in several t=
axa such as butterflies, wild bees and moths, are in parallel with a severe=
 loss of total aerial insect biomass, suggesting that it is not only the vu=
lnerable species, but the flying insect community as a whole, that has been=
 decimated over the last few decades.<br>
&gt;<br>
&gt; It is particularly concerning since these measurements were made in pr=
otected nature areas and not in those areas impacted by more extensive huma=
n activity.<br>
&gt;<br>
