Glacial survival and local adaptation in an alpine leaf beetle.
The challenge in defining conservation units so that they represent evolutionary entities has been to combine both genetic properties and ecological significance. Here we make use of the complexity of the European Alps, with their genetic landscape shaped by geographical barriers and postglacial colonization, to examine the correlation between ecological and genetic divergence. Montane species,...
متن کاملFeatures of glacial valley profiles simply explained
[1] Glacial occupation of alpine valleys results in a distinct signature in the long-valley profile, including steepening of the profile in the headwaters, flattening at lower elevations, and a step in the profile at the convergence of headwater tributaries. We present analytic results for glacial erosion patterns by making the following assumptions: (1) the initial profile is linear, (2) the w...
متن کاملAbrupt glacial climate changes due to stochastic resonance.
Using an ocean-atmosphere climate model we demonstrate that stochastic resonance could be an important mechanism for millennial-scale climate variability during glacial times. We propose that the glacial ocean circulation, unlike today's, was an excitable system with a stable and a weakly unstable mode of operation, and that a combination of weak periodic forcing and plausible-amplitude stochas...
متن کاملDiscussion: Clinical Features (Part One)
Dr. Benach questioned whether the relationship between HLA-DR2 and Lyme disease has held up. Dr. Steere responded that additional patients have been tested since the initial report in 1979. It seems mainly that patients with neurologic involvement, arthritis or chronic arthritis, have an increased frequency of HLA-DR2. As yet, HLA phenotypes have not been determined for European patients. Dr. E...
متن کاملDiscussion: Clinical Features (Part Two)
Dr. Malawista stated that differences in the presentation of disease in the U.S. and Europe stood out among the various speakers: for example, the lack in Europe of the excruciating though often brief headaches that one sees in the U.S., the lack of multiple secondary annular lesions, and the relative lack of arthritis. In addition, in the U.S. one does not frequently find local neuralgia near ...
