Potential research projects for students
(1) Recognition of poisonous spider (toxicity level)
Spiders are the largest class of arachnids and rank seventh in total species diversity among all living organisms. There are potentially hundreds (maybe thousands) of spider species anywhere in the world. While many are harmless to human, some are very poisonous. It would be nice to tell if a spider is poisonous (or extremely poisonous) by an image or an instantly taken photo.

— May need to crawl the web for spider images and whether the associated spider is posionous.
(2) Analysis of tree rings of California redwoods (giant sequoias)
Giant sequoias are one of the longest living species in the world. According to Los Angeles Times, the oldest coastal redwood is 2,520 years old and the oldest giant sequoia is about 3,200 years old. The tree growth would keep a faithful record of long-term climate in a large geogological span, and for this reason they are called the “living fossils”. They can be an ideal proxy to study climate change or historical weather anomaly.
