Dallas hospital has been downgraded from good to fair after being transferred to the National Institutes of Health Clinical center in maryland. An email from the ceo of Frontier Airlines says this woman, amber vinson, may have been at a more advantaged stage of the illness than first thought when she traveled on Frontier Airlines flights between dallas and cleveland. The email to employees says crew members on the flights are at a very low risk of exposure. And the doctor who treated all three ebola patients in dallas is speaking publicly for the first time talking about how those two nurses caught the virus from Thomas Eric Duncan. Dr. Gary weinstein says, quote, i think these two nurses took c ....
Tropical moist forests harbor much of the world’s biodiversity, but this diversity is not evenly distributed globally, with tropical moist forests in the Neotropics and Indomalaya generally exhibiting much greater diversity than in the Afrotropics. Here, we assess the ubiquity of this “pantropical diversity disparity” (PDD) using the present-day distributions of over 150,000 species of plants and animals, and we compare these distributions with a spatial model of diversification combined with reconstructions of plate tectonics, temperature, and aridity. Our study demonstrates that differences in paleoenvironmental dynamics between continents, including mountain building, aridification, and global temperature fluxes, can explain the PDD by shaping spatial and temporal patterns of species origination and extinction, providing a close match to observed distributions of plants and animals.
Data and R scripts used in this study are deposited in a public repository on EnviDat, & ....
2Institute of Environmental Sciences, Koblenz-Landau University, Landau, Germany 3Swiss Federal Institute for Forest, Snow, and Landscape Research (WSL), Birmensdorf, Switzerland Combined effects of climate change and increasing anthropogenic water demand have increased and extended dry period occurrences in rivers worldwide. Riverbed drying can significantly affect sediment microorganisms, crucial drivers of biogeochemical processes in lotic systems. In this study, we evaluated how sediment bacterial and fungal community structure and composition (based on 16S rRNA gene and ITS metabarcoding) and microbial functions (community respiration and extracellular enzymatic activities) respond to different riverbed drying intensities over 90 days. Riverbed sediment collected in a flowing reach of the Spree river in northeastern Germany was dried under different rates in outdoor mesocosms during the summer months of 2018. Our results demonstrate that drying attributes (duration an ....
