Identifying the optimal course delivery platform in an undergraduate animal behavior research course.

There is a critical need to evaluate pedagogical delivery platforms best suited for undergraduates in the information age. Our goal was to identify the optimum course delivery platform for a basic research course based on student performance and critical thinking scores. Students were expected to plan, conduct, and report on an animal behavior research project of their own design.

A simple, field-friendly technique for cryopreserving semen from Asian elephants (Elephas maximus).

The specific objectives of the present study were to investigate the effects of manual seeding, differing freeze and thaw rates as well as storage for 24h at 4°C prior to cryopreservation on post-thaw sperm quality in Asian elephants. Extended semen was cooled in an equitainer to 4°C, frozen in liquid nitrogen vapour at various rates with and without manual seeding or in a dry shipper and thawed at 37, 50 and 75°C. There was a significant effect of freeze rate on post-thaw motility (P<0.
