To our knowledge, this article presents the first test of the hypothesis that variation in size-dependent predation risk on hatchings can cause adaptive shifts in the timing of egg hatching and thus on the size and developmental stage of new hatchlings. Earlier field experiments documented heavy predation by flatworms (Phagocotus gracilis) on smaller, less(More)
T oday's commercial drug information sys­ tems follow a variety of naming conven­ tions. For example, cooperating hospitals might use different systems, and find their data incompatible. Even within a hospital, there might be one system for ordering, another for inventory management, and still another for recording dose adjustments or checking drug(More)
Slowing rates of global biodiversity loss requires preventing species extinctions. Here we pinpoint centers of imminent extinction, where highly threatened species are confined to single sites. Within five globally assessed taxa (i.e., mammals, birds, selected reptiles, amphibians, and conifers), we find 794 such species, three times the number recorded as(More)
Founded in 1948, The World Conservation Union brings together States, government agencies and a diverse range of non-governmental organizations in a unique world partnership: over 1,000 members in all, spread across some 140 countries. As a Union, IUCN seeks to influence, encourage and assist societies throughout the world to conserve the integrity and(More)
OBJECTIVE In the 6 years since the National Library of Medicine began monthly releases of RxNorm, RxNorm has become a central resource for communicating about clinical drugs and supporting interoperation between drug vocabularies. MATERIALS AND METHODS Built on the idea of a normalized name for a medication at a given level of abstraction, RxNorm provides(More)
BACKGROUND Operating rooms (ORs) are resource-intense and costly hospital units. Maximizing OR efficiency is essential to maintaining an economically viable institution. OR efficiency projects often focus on a limited number of ORs or cases. Efforts across an entire OR suite have not been reported. Lean and Six Sigma methodologies were developed in the(More)
This special issue of the American Journal of Health Promotion on ‘‘Health Promoting Community Design’’ highlights the most recent research into how the built environment affects health. This emerging research provides another chapter in the rich history of public health and its quest to overcome obstacles to health through shaping the environment in which(More)
Introduced species have contributed significantly to the extinction of endemic species on islands. They also create new selection pressures on their prey that may result in modified life history strategies. Introduced viperine snakes (Natrix maura) have been implicated in the decline of the endemic midwife toad of Mallorca (Alytes muletensis). A comparison(More)
Perspective F rogs from Madagascar constitute one of the richest groups of amphibian fauna in the world, with currently 238 described species; caecilians and salamanders are absent [1]. Several frog radiations of the island are species-rich and parallel lemurs and tenrecs in their astonishing morphological and ecological diversity. According to the Global(More)
The viperine snake (Natrix maura) is an important agent of decline of the threatened midwife toad (Alytes muletensis) of Mallorca. However, there is a paucity of biological data to support the notion that the viperine snake is an introduced species to the island. Here we compare mitochondrial cytochrome b gene sequences and genomic ISSR-PCR fingerprints(More)
