Rather, saltational evolution as we consider it here, is targeted and relatively rapid change in specific characters (and their coding genes) of apparent survival importance while the overall genome apparently evolves at the same pace as in non-saltational, comparatively static, sister taxa.
While the study showed birds from better-lit areas foraged for longer, there was no apparent survival advantage.
"As soon as you advance the date of diagnosis with any screening test, you will improve the apparent survival," said Dr. Barnett Kramer, who is associate director for disease prevention at the National Institutes of Health.
His apparent survival lifted a pall from the White House and sent a surge of energy through conservative America.The second bit of good news is that Harriet Miers's withdrawal provided Mr Bush with an opportunity to choose a more appropriate candidate.
However for Bobolinks, increasing adult apparent survival, juvenile apparent survival, or preference by changing habitat selection cues for late-hayed fields (highest quality) only slightly decreased the rate of decline.
We hypothesized that this apparent survival advantage is due to a more favorable nutritional/inflammatory profile in minority hemodialysis patients.
A combination of Pradel's model and Pollock's robust design was applied to estimate abundance and other population parameters, such as apparent survival, capture probability (p) and seniority probability.
We examined whether a series of demographic processes, including probabilities of remaining at a specific wintering site, over-winter and annual apparent survival, winter stopover duration, and abundance varied among oiled and unoiled habitats.
The results showed little variation in survival of the species during the regular annual dry season and a decline greater than 50% in apparent survival caused by severe drought.
To assess population viability of grassland songbirds at a regional scale (∼150,000 ha), we quantified Savannah Sparrow Passerculus sandwichensis and Bobolink Dolichonyx oryzivorus annual productivity, adult apparent survival, habitat selection, and density in the four most (regionally) common grassland treatments.
Maybe those that did screen also provided better care and the apparent survival benefit was more about treatment than screening.
