One of the top five hotspots where these extinctions are forecast to be highest is in the tropical Andes, a region where coffee is also grown. Encouraging shade coffee from the Colombian Andes in particular, in a country where sun coffee has been promoted, is especially important.

According to his calculations, somewhere between 213,830 and 547,500 monophagous insect species are trending towards extinction in biodiversity hotspots. </blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://conservationmaven.com/frontpage/2009/10/1/specialist-insects-undergoing-silent-mass-extinction.html"><P>Monophage insects are particularly sensitive to extinction risk. As specialist herbivores, they rely on a single plant species for food. If their host plant goes extinct, they have to make a long shot evolutionary leap of adapting to another plant species in order to continue with their own survival.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://conservationmaven.com/frontpage/2009/10/1/specialist-insects-undergoing-silent-mass-extinction.html">Certain hotspots are faring much worse than others.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/0E86A0F7-ED6A-4405-AC7E-B06E376C4F3B/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
