This field guide is the culmination of a semester-long course in Field Biology taught at Brandeis University by Dan Perlman.

All photographs used on this website were obtained with either a Nikon Coolpix 990 or 995 digital camera. Non-photo images were created and all photo editing was done in Adobe Photoshop 6.0/7.0. Adobe GoLive 5.0 was used for webpage/HTML/JavaScript editing.

This field guide would not have been possible without the assistance of the following people:

Dan Perlman, for teaching a wonderful class, for providing me with the opportunity to do a project like this one, for inspiring me with his knowledge, passion and enthusiasm for the natural world, and for the use of his digital camera.

Chris Bersbach, for reviewing countless drafts of webpages, and for trading his brilliant ideas for mine.

Deb Verhoff, Todd Hartigan and everyone else at the ITRC, for technological support.

Kevin Kenlan, for help identifying and locating certain species.

Sara Mason, for viewing draft webpages, moral support and tolerating my compulsive tree-identifying tendencies this semester.
