6 [1] We combined observations from four eddy covariance towers with remote sensing to 7 better understand the altitudinal patterns of climate, plant phenology, Gross Ecosystem 8 CO2 Uptake, and Evapotranspiration (ET) around the upper Kings River basin in the 9 southern Sierra Nevada Mountains. Precipitation (P) increased with elevation to 500 m, 10 and more gradually at higher elevations, whi...

Mountain snowpacks directly and indirectly influence soil temperature (Tsoil) and soil water content (h). Vegetation, soil organisms, and associated biogeochemical processes certainly respond to snowpack-related variability in the soil biophysical environment, but there is currently a poor understanding of how snow-soil interactions vary in time and across the mountain landscape. Using data fro...

The sugarbeet root maggot Tetanops myopaeformis (Röder) overwinters as a freeze-tolerant third-instar larva. Although most larvae are considered to overwinter for only 1 year, some may exhibit prolonged diapause in the field. In the laboratory, they can live for over 5 years using a combination of diapause and post-diapause quiescence. In the present study, the cold survival strategies of these...

P erformance and high availability are critical at Web sites that receive large numbers of requests. This article presents several techniques—including redundant hardware, load balancing, Web server acceleration, and efficient management of dynamic data—that can be used at popular sites to improve performance and availability. We describe how we deployed several of these techniques at the offic...

In January/February 2006, heavy snowfalls in Bavaria (Germany) lead to a series of infrastructural damage of catastrophic nature. Since on many collapsed roofs the total snow load was not exceptional, serious engineering deficiencies in roof construction and a sudden rise in the total snow load were considered to be the trigger of the events. An analysis of the then meteorological conditions re...

Expected climate change estimations for the Carpathian basin and especially, Hungary, are summarized for the 2071-2100 period on the basis of the results from the project PRUDENCE. Different regional climate models (RCMs) used 50 km as the horizontal spatial resolution, and evaluated the A2 and B2 global emission scenarios. Results suggest that in case of temperature, a warming trend is evident...

Grenoble taxpayers were not very happy to pay local taxes up to 1992 for covering the financial deficit from the 1968 Winter Games! The 1976 Summer Olympics in Montreal outperformed Grenoble Winter Olympics in terms of deficit: the latter was so deep that Montreal taxpayers had been repaying the debt until 2006, for thirty years. After Montreal's financial mess, the number of candidate cities w...

[1] The California Institute of Technology/Jet Propulsion Laboratory two-dimensional (2-D), three-dimensional (3-D) GEOS-Chem, and 3-D MOZART-2 chemistry and transport models (CTMs), driven respectively by NCEP2, GEOS-4, and NCEP1 reanalysis data, have been used to simulate upper tropospheric CO2 from 2000 to 2004. Model results of CO2 mixing ratios agree well with monthly mean aircraft observa...

1. Lakeside Phragmites australis reed beds were mown or bumt in winter as a eountermeasure against the die-back of reeds in Lake Constanee-Untersee. 2. The effeet of winter harvesting and buming on the meehanieal resistanee of reeds against waves and washes was investigated using the PMR model. This model postulates that the pereentage of meehanieally damaged shoots of a reed stand is a monoton...

[1] This study uses instrument records and geostatistical modeling to examine hydrologically important temporal and spatial patterns of seasonal precipitation associated with the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) in a mountainous region of northern New Mexico. PDO is the more dominant factor, compared to ENSO, with a larger influence on winter and spr...
