A presentation of some of the recent findings Dr. Ramirez and her students have made in their spider lab concerning the sex life of spiders, specifically focusing on whether female trapdoor spiders mate once or many times, and on how the lack of a Y-chromosome in a local leaf litter spider is driving genetic differences between males and females. Includes discussion of teaching at Loyola. Spiders begins at time 7:40.

Woodlouse SpiderDysdera Crocata.
Originated in the Mediterranean area, now cosmopolitan distribution. Hunts woodlice,
sowbugs and pillbugs under logs, rocks, bricks, plant pots and in leaf litter in warm places.
