<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Hello Maria, Liz, and interested listserve members, </DIV>
<DIV> </DIV>
<DIV>I am responding to a recent query requesting information about studies involving alien pollinators. I have done a number of such studies, many with former post doc Hong Liu, involving two tropical American solitary bees that have naturalized in southern Florida. One is the orchid bee, Euglossa viridissima, and the other an oil-collecting bee, Centris nitida. We also did a study on the pollination of the invasive weed Paederia foetida which was pollinated in open habitats in Florida primarily by honey bees.</DIV>
<DIV> </DIV>
<DIV>I am continuing to do research on these alien pollinators and also the pollination of alien plants.</DIV>
<DIV> </DIV>
<DIV>Best Regards, Bob </DIV>

<DIV> </DIV>
<DIV>Below are papers published on these studies. I can provide pdfs to interested people.</DIV>
