Evidence of Tree Species’ Range Shifts in a Complex Landscape
Climate change is expected to change the distribution of species. For long-lived, sessile species such as trees, tracking the warming climate depends on seedling colonization of newly favorable areas. We compare the distribution of seedlings and mature trees for all but the rarest tree species in California, Oregon and Washington, United States of America, a large, environmentally diverse regio...
متن کاملUtilization of tree species stratum data in forest planning simulations
The objective here was to investigate the theoretical benefit of using tree species stratum forest inventory data instead of stand-level mean data in forest-planning simulations. This comparison was based on timing differences in thinning and clear-cuttings during a 20-year simulation period. The development of stand characteristics (age, basalarea, volume, dominant height, mean height, mean di...

Hypolipidemia: A Word of Caution
Introduction Hypolipidemia is a decrease in plasma lipoprotein caused by primary (genetic) or secondary (acquired) factors. It is usually asymptomatic and diagnosed incidentally on routine lipid screening. The first report of hypocholesterolemia in the medical literature was in 1911 by Chauffard and coworkers, in patients with active tuberculosis [1]. Since then (about 95 years), only few dozen...
متن کاملBisphosphonates--a word of caution.
