摘要:Abstract(#br)Alpine ice varies from pure ice glaciers to partially debris-covered glaciers to rock glaciers, as defined by the degree of debris cover. In many low- to mid-latitude mountain ranges, the few bare ice glaciers that do exist in the present climate are small and are fo...

摘要:Abstract(#br)Many debris-covered glaciers have broadly similar debris thickness patterns: surface debris thickens and tends to transition from convex- to concave-up-down glacier. We explain this pattern using theory (analytical and numerical models) paired with empirical observat...

摘要:Abstract(#br)Gophers are significant geomorphic agents in many landscapes. We document activity of the northern pocket gopher ( Thomomys talpoides ) in two small subalpine meadows (1050–1800 m 2 ) of the Front Range, Colorado, USA. We tracked locations and volumes of mounds ...

摘要:Abstract(#br)Background(#br)Infants are at risk for vitamin K deficiency bleeding (VKDB) because of limited stores of vitamin K (VK) at birth and a low concentration of VK in human breast milk. Therefore, the administration of intramuscular (IM) VK at birth has been recommended s...

摘要:Abstract(#br)10 Be concentrations in stream sediments are commonly employed to calculate basin-averaged denudation rates. Such calculations assume that denudation is steady in time and that quartz is uniformly distributed in the watershed. The 10 Be concentrations in stream sedim...
