This study used air temperatures from a suite of regional climate models participating in the North American Climate Change Assessment Program (NARCCAP) together with two atmospheric reanalysis datasets to investigate changes in freezing days (defined as days with daily average temperature below freezing) likely to occur between 30-yr baseline (I97I-2000) and midcentury (2041-70) periods across...

but snow cover will decrease. In this paper, we examine potential effects of a reduction in snow cover on northWe measured deciduous forest soil temperatures under control (unmanipulated) and snow-free (where snow is manually removed) eastern forests by examining soil temperatures under conditions for four winters (at three soil depths) to determine effects control and snow-free (where snow is ...

Leaves of overwintering evergreen rhododendrons are typically exposed to freezing temperatures and high light during winters which can potentially result in photon flux exceeding that required for photochemistry. This excess energy, if not dissipated as heat or fluorescence, may cause photooxidative damage to PSII. The goal of this study is to compare the photoprotection strategies during seaso...

Plants vary greatly in their ability to survive freezing temperatures. At one extreme are plants from tropical regions that have virtually no capacity to survive even the slightest freeze. In contrast, herbaceous plants from temperate regions generally survive freezing temperatures ranging from 25°C to 230°C, depending on the species, whereas perennials in the boreal forests routinely survive w...

chickpea (Cicer arietinum L.) is reportedly controlled by at least five genes with tolerance dominant over Lentil (Lens culinaris Medik.) germplasm with sufficient winter susceptibility (Malhotra and Singh, 1990). hardiness to survive most winters in cold northern areas is available. However, the use of that germplasm in breeding programs is hampered One of the major problems in characterizing ...

Accurate simulation of soil water and heat transfer is critical to understand surface hydrology under cold conditions. Using an extended freezing code in HYDRUS-1D (freezing module), this study was conducted: (1) to evaluate the freezing module using field data collected in a grazed steppe of Inner Mongolia; and (2) to further simulate grazing effects on frozen soil hydrological processes. The ...
