Looking beyond biodiversity to explain community invasibility

...ners, Cadenasso, and Pickett analysed data from 42 continuous years of sampling old field succession. In contrast to the experimental literature, they found that when richness was related to invasion dynamics, it enhanced rather than impeded invasion.

For the Science study, Gilg, Hanski and Sittler compiled the 15 year's-worth of data for each of the five species. The results showed the stoats' population cycles lagging behind those of the lemmings. This was expect...

Ki-67 biomarker a strong predictor of outcome for prostate cancer patients

..."The relationship of Ki-67 to patient outcome is a continuous function, wherein the higher the percent of Ki-67, the greater the risk of an adverse result. In addition, Ki-67, along with PSA, Gleason score and stage, appears to be valuable in determining whether high-risk patients may be spared long-term andro...
