Abstract On September 5, 2019, the Veslemannen unstable rock slope (54,000 m 3 ) in Romsdalen, Western Norway, failed catastrophically after 5 years of continuous monitoring. During this period, weakened while precursor movements increased progressively, particular from 2017. Measured displacement prior to failure was around 19 upper parts instability and 4–5 toe area. The pre-failure were usua...

Overwintering and spring recovery of pine needles have important ecological significance. The natural changes in physiological state, photosynthetic function, material metabolism Pinus densiflora Siebold & Zucc. from the autumn 2020 to 2021 were assessed. rate (Pn) P. decreased first then increased, with maximum Pn observed autumn. After experiencing sub-zero temperatures winter, still perf...

In almond, late frost is the main factor determining viability of culture in cold areas, and flowering remains key addressing this issue. Climate change causing an increase frequency extreme weather events. 2021, period Spain after Filomena storm (11–14 January), which temperatures reached ?20 °C some regions, was a clear expression regard. many almond-growing these low affected closed flower b...

Epidemics of Mycoplasma pneumoniae have recently been reported from England and Wales and from Denmark. A similar increase in M. pneumoniae infections was noted in Norway late autumn 2011.The epidemic has resulted in shortage of erythromycin and the use of alternative antibiotics has been recommended.

When the Arctic Research Laboratory at Point Barrow, Alaska, was ready for use in 1947, it was late autumn. Frost could set in at any time and render unavailable precious material for our projected respiratory studies. This situation brought about an acute need for many more micro respirometers than the dozen we had, and prompted the construction of simple, plastic respirometers drilled in bloc...

The evidence presented indicates that cabbage maturing in the spring and summer months has little goiter-produdag power. Cabbage maturing in the late autumn has much greater goiter-produdng power, although this shows considerable variation in different years. It has not been possible to correlate available meteorological data with these variations.

Asian highly pathogenic avian influenza A(H5N8) viruses spread into North America in 2014 during autumn bird migration. Complete genome sequencing and phylogenetic analysis of 32 H5 viruses identified novel H5N1, H5N2, and H5N8 viruses that emerged in late 2014 through reassortment with North American low-pathogenicity avian influenza viruses.

Abstract Permafrost and seasonally frozen ground are important surface features in highlatitudes. Because of this, a soil-frost parameterization was added to the Penn State University/NCAR mesoscale meteorological model MM5 in combination with the well validated hydro-thermodynamic soil vegetation scheme HTSVS, which takes into account among other things soil freezing and thawing. Reanalysis of...

Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes. Such up-regulation of frost tolerance is controlled by Cbf transcription factors. Molybdenum (Mo) application has been shown to enhance frost tolerance of wheat and this study aimed to investigate...

[1] Frost boils in the Arctic are a manifestation of patterned ground in the form of nonsorted circles. Active frost boils involve convection of water through the soil that can bring basic salts from depth to the surface. As such, active frost boils can mitigate acidification and thereby strongly influence the type of vegetation supported by Arctic soils. The presence or absence of active frost...
