This is known as xanthophyll cycling. The xanthophylls are members of the carotenoid pigments which are responsible for the colorful leaves on trees in the autumn.</div> <div> The varying levels of xanthophyll cycling produced in response to different environmental stressors cause varying changes in the wavelengths of light reflected back from a plant's surface (i.e. very small changes in leaf colour). This may be detected by sensors (known as hyperspectral detectors) mounted on aircraft and may be used to assess ecosystem health rapidly from the air.</div> </tD> </tR> <tR> <tD VALIGN=TOP BGCOLOR=#FFFFFF HEIGHT= 73 ><NOBR><div> <B><IMG SRC="1385d43c0.gif" border=0 width="468" height="60" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> </NOBR></tD> </tR> </TABLE></div> <div> <TABLE BORDER="4" CELLPADDING="2" CELLSPACING="1" WIDTH="682" BORDERCOLORLIGHT="#CCFFFF" BORDERCOLORDARK="#336600" FRAME="BOX" RULES="ALL" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 75 WIDTH="666"><div>   <form method="get" action="http://www.google.com/custom" target="google_window"> <table border="0" bgcolor="#000000"> <tr><td nowrap="nowrap" valign="top" align="left" height="32"> <a href="http://www.google.com/"> <img src="http://www.google.com/logos/Logo_25blk.gif" border="0" alt="Google" align="middle"></img></a> </td> <td nowrap="nowrap"> <input type="hidden" name="domains" value="gaianlife.co.uk"></input> <label for="sbi" style="display: none">Enter your search terms</label> <input type="text" name="q" size="31" maxlength="255" value="" id="sbi"></input> <label for="sbb" style="display: none">Submit search form</label> <input type="submit" name="sa" value="Search" id="sbb"></input> </td></tr> <tr> <td> </td> <td nowrap="nowrap"> <table> <tr> <td> <input type="radio" name="sitesearch" value="" checked id="ss0"></input> <label for="ss0" title="Search the Web"><font size="-1" color="#ffffff">Web</font></label></td> <td> <input type="radio" name="sitesearch" value="gaianlife.co.uk" id="ss1"></input> <label for="ss1" title="Search gaianlife.co.uk"><font size="-1" color="#ffffff">gaianlife.co.uk</font></label></td> </tr> </table> <input type="hidden" name="client" value="pub-7833537822921622"></input> <input type="hidden" name="forid" value="1"></input> <input type="hidden" name="channel" value="0644663851"></input> <input type="hidden" name="ie" value="ISO-8859-1"></input> <input type="hidden" name="oe" value="ISO-8859-1"></input> <input type="hidden" name="safe" value="active"></input> <input type="hidden" name="cof" value="GALT:#008000;GL:1;DIV:#000000;VLC:CAF99B;AH:center;BGC:000000;LBGC:000000;ALC:2D8930;LC:2D8930;T:78B749;GFNT:0D8F63;GIMP:0D8F63;LH:50;LW:55;L:http://gaianlife.co.uk/logo.jpg;S:http://gaianlife.co.uk;FORID:1"></input> <input type="hidden" name="hl" value="en"></input> </td></tr></table> </form>   </div> </tD> </tR> <tR> <tD VALIGN=TOP HEIGHT= 75 WIDTH="666"><div>  <script type="text/javascript"> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script>  </div> </tD> </tR> </TABLE></div> <bR> <div> <TABLE BORDER="4" CELLPADDING="2" CELLSPACING="1" WIDTH="682" BORDERCOLORLIGHT="#66FF00" BORDERCOLORDARK="#336600" FRAME="BOX" RULES="ALL" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 75 WIDTH="666"><div>  <script language=javascript type="text/javascript" src="http://ss.webring.com/navbar?f=j;y=gaianlife;u=defurl"></script><noscript><center> <table bgcolor=gray cellspacing=0 border=2><tr> <td><table cellpadding=2 cellspacing=0 border=0><tr><td align=center> <font face=arial size=-1>This site is a member of WebRing. <br>To browse visit <a href="http://ss.webring.com/navbar?f=l;y=gaianlife;u=defurl"> Here</a>.</font></td></tr></table></td></tr></table> </center></noscript>  </div> </tD> </tR> </TABLE></div> <div> <TABLE BORDER="4" CELLPADDING="2" CELLSPACING="1" WIDTH="683" BORDERCOLORLIGHT="#CCFFFF" BORDERCOLORDARK="#336600" FRAME="BOX" RULES="ALL" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 257 WIDTH="667"><div> <IMG SRC="1d0507ed0.jpg" border=0 width="263" height="237" ALIGN="LEFT" HSPACE="0" VSPACE="0"></div> <div> The<B> Gaian Life</B><FONT SIZE="4" COLOR="#CCFFFF" FACE="Symbol" >Ô</FONT><FONT SIZE="4" COLOR="#FFFFFF" FACE="Arial" > </FONT>website<FONT SIZE="4" COLOR="#FFFFFF" FACE="Arial" > </FONT><FONT SIZE="4" COLOR="#FFFFFF" FACE="Symbol" >Ó</FONT><FONT SIZE="4" COLOR="#FFFFFF" FACE="Arial" > </FONT>2007 and site contents (excluding linked sites) were designed & created by H.
