Three Steps to Adapt Case Studies for Synchronous and Asynchronous Online Learning.

Pandemic SARS-CoV-2 has ushered in a renewed interest in science along with rapid changes to educational modalities. While technology provides a variety of ways to convey learning resources, the incorporation of alternate modalities can be intimidating for those designing curricula. We propose strategies to permit rapid adaptation of curricula to achieve learning in synchronous, asynchronous, or hybrid learning environments.

The effects of the timing of exposure to cadmium on the oviposition behavior of Drosophila melanogaster.

Animals can greatly increase their fitness by choosing oviposition sites free from damaging substances such as the heavy metal cadmium (Cd). Previous research has shown that Drosophila melanogaster reared on uncontaminated media lay fewer eggs on substrates containing Cd. In this study, we examined the effects of prior exposure to Cd on oviposition site preference.

Individual discrimination by odors in sibling prairie voles (Microtus ochrogaster).

The habituation-discrimination paradigm has been used widely to demonstrate that animals can detect individually distinctive odors of unfamiliar conspecifics. By using a modification of the habituation-discrimination technique, Todrank et al. (Anim Behav 55:377-386, 1998) found that golden hamsters discriminate between the individual odors of their own familiar brothers but cannot discriminate between the odors of two siblings that are unrelated and unfamiliar to the subject.
