We provide the first global test of the idea that introduced species have greater seed dispersal distances than do native species, using data for 51 introduced and 360 native species from the global literature. Counter to our expectations, there was no significant difference in mean or maximum dispersal distance between introduced and native species. Next, we asked whether differences in disper...

Bullfrogs, Lithobates catesbeianus, have been described as major vectors of the amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd). Bd is widespread throughout the range of amphibians yet varies considerably within and among populations in prevalence and host impact. In our study, the presence of L. catesbeianus is correlated with a 2.5 increase in Bd prevalence in treefrogs, and the...

Multiple sulfatase deficiency (MSD) is an inherited lysosomal storage disease characterized by the deficiency of at least seven sulfatases. The basic defect in MSD is thought to be in a post-translational modification common to all sulfatases. In accordance with this concept, RNAs of normal size and amount were detected in MSD fibroblasts for three sulfatases tested. cDNAs encoding arylsulfatas...

CONTEXT Although the introduction of a new method is generally hailed as a boon to contraceptive prevalence, uptake of new methods can reduce the use of existing methods. It is important to examine changing patterns of contraceptive use and method mix after the introduction of new methods. METHODS Demographic and Health Survey data from 13 countries were used to analyze changes in method use ...

Climate change is predicted to place up to one in six species at risk of extinction in coming decades, but extinction probability is likely to be influenced further by biotic interactions such as predation. We use structural equation modelling to integrate results from remote camera trapping and long-term (17-22 years) regional-scale (8000 km2) datasets on vegetation and small vertebrates (grea...

Profit Sharing and Training We analyze the impact of profit sharing on the share of workers receiving training. An effect is plausible because: 1) profit sharing is a credible commitment by firms to reward firmspecific skills acquired by formal or informal training, 2) profit sharing may reduce turnover and increase the returns to training, 3) a common payment for the whole workforce leads to p...
