    Leta,

    Good points. There are hardware and performance limits which prevent us from returning more than 1500 species at a time in this version of the Species Distribution Grid website. The good news is that we are currently redeveloping that site. Thank you for your suggestions which will be forwarded to our development team to be considered for future revisions to our website(s). So your comment is right on time! Glad to hear that you were able to get your data.

    this is not supported by the openlayers layer switcher as far as i know. support for legends in our client is custom built functionality.

    you just need to perform a getlegend request to the map server:

    http://sedac.ciesin.columbia.edu/geoserver/wms?request=GetLegendGraphic&format=image%2Fpng&layer=gpw-v3-population-density_2000&width=15&height=15&legend_options=border:false;mx:0.05;my:0.02;dx:0.2;dy:0.07;fontSize:11;bandInfo:false;

    (hit that url in your browser and you'll get a legend)

    note the value of 'layer' is the same value used to request the tiles from the server. the 'style' param is also accepted.

    As previously mentioned, we're looking to provide more details & documentation. We're preparing for a new major release, and will be included in this new release.

    One thing to note is that our cached layers only work with the following resolutions:
    [
    2.00167551711953,
    1.0008377585597652,
    0.5004188792798824,
    0.33361258618658834,
    0.16680629309329414,
    0.08340314654664707,
    0.03336125861865884,
    0.016680629309329415,
    0.008340314654664708
    ]

    our non-cached service url is:
    http://sedac.ciesin.columbia.edu/geoserver/ows.

    use that instead of:
    http://sedac.ciesin.columbia.edu/geoserver/gwc/service/wms

    note -- this means it will be slower to render, since its not cached. if you want to use our cached service, be sure to set the resolutions above within your map properties:

    new OpenLayers.Map("id", {
    resolutions: [array-displayed-above!]
    });

    hopefully that should do it.
