Butterflies as indicators of climate change. | In Britain, most butterfly species reach the limit of their range due to climate. Such species are the ones most likely to show rapid adaptations to climate change. There are indications that several butterfly species are adapting and that these insects make good indicators of the likely effects of climate change on ot... | 18,717,369 |
Evaluation of peri-implant bone loss around platform-switched implants. | This clinical and radiographic prospective study evaluated bone loss around two-piece implants that were restored according to the platform-switching protocol.

Probe-specific proportion task repetition effects on switching costs. | In two experiments, participants were presented with successive presentations of animal names (e.g., GORILLA, WHALE)--a prime display followed by a probe display. In response to each display, participants judged either the typical habitat or the relative size of those animals, repeating the same task in response to bot... | 18,717,381 |
Dividing attention across feature dimensions in statistical processing of perceptual groups. | Statistical processing has been shown in the perception of several visual dimensions, including size, speed, direction of motion, and orientation. Chong and Treisman (2005) found no decrement when people simultaneously averaged two sets on a single dimension, size. What happens when attention is divided between differe... | 18,717,382 |
