    evidence of herbivory within a wild population at our field site in Amherst NH an observation that is consistent with other reports of cows shunning the plant in pastures Anti herbivory compounds have not been extracted and identified for S hebecarpa but other Senna species are know to be purgatives or mild laxatives due to the presence of cathartic acid which is eliminated by digestion In our study we examined the anti herbivore defenses in leaves of S hebecarpa using a brine shrimp bioassay Brine shrimp Artemia salina are one of the most commonly used bioassays for plant toxins because they can be considered naive organisms with respect to plant toxins in that they have not been exposed to land plants during their evolutionary history We exposed the shrimp to extracts of leaf tissue over a broad range of concentrations in order to construct a dose response curve from which we calculated the concentration of extract that kills 25 of shrimp within 24 hours lethal concentration LC 25 and 50 within 48 hours LC 50 We compared the findings for S hebecarpa to other wildflowers that are found in similar disturbed habitats two of which are known to produce substantial

    we presented research on the effectiveness for improving students botany learning of our Leonardo Strategy of online discussion board design and our Polymath System for students marginal annotation of their science textbooks A third study quality improvement tool we have begun using is Francesco Cirillo s Pomodoro Technique for time management 2009 which originated in Italy and has found wide acceptance there among computer code writers Results of our case study of one research university science graduate student indicates that a developing scholar s self management of the focus quality of her study time and the expansion of her cumulative study time can be substantially improved in measurable ways using the Pomodoro Technique Our study participant was initially intrigued by its simplicity and the ease with which she could apply it to her daily routine Her perception was that there were two keys to her success a its time boxing structure and b its insistence upon vigilant interruption avoidance during study times The latter finding aligns well with the recently published human productivity research of Heath and Heath 2010 Broader Impacts Log in to add this item to your schedule 1 Louisiana State University Dept of Educational Theory Policy Practice

    well as to handle optimization uncertainty in reconstructing biogeographic histories using DIVA Both methods have been newly implemented in the S DIVA package Statistical Dispersal Vicariance Analysis We used the S DIVA program to reconstruct the biogeographic history of Cornales using 4500 Bayesian trees with fossil distributions included and excluded Initial analyses were run using the 1 N method to estimate the frequency of occurrence of a range at each node on each tree where N is the total number of optimal ranges at the node Results from the analyses showed that adding fossil distributions resulted in highly supported ancestral distributions at eight of ten nodes which were unresolved when fossil distributions were omitted Additional analyses of the two clades with unresolved ancestral distributions were performed using the i Rt method to determine the actual frequency of a range at each node on each tree These additional analyses resolved distributions at the two nodes but with relatively low support S DIVA is a fast user friendly program with a graphical interface We compared the results with those from the likelihood based method on LAGRANGE The ancestral ranges of Cornales from S DIVA are comparable to those from LAGRANGE LAGRANGE requires
