In recent years, the economic impact of grape and wine industry within Texas has significantly increased. The majority grapes grown in are produced High Plains American Viticultural Area (AVA). Vineyards this AVA subject to late spring frosts that may potentially reduce crop yields, lower fruit quality. Objectives experiment were compare growth fruitfulness shoots from primary secondary buds V....

Based on the analysis of frequency anomalous anatomical structures in wood Siberian larch and spruce (frost rings, light false as well missing narrow rings), we reconstructed a timeline climatic extremes (summer frosts, sharp multiday decreases air temperature during growing season, low average summer temperatures) Yamal (Western Siberia) over last 4500 years. In total, 229 years were determine...

Spring frosts damage crops that have weakened freezing resistance after germination. We developed a machine learning (ML)-based frost-classification model and optimized it for orchard farming environments. First, logistic regression, decision tree, random forest, support vector models were trained using balanced Korea Meteorological Administration (KMA) Automated Synoptic Observing System (ASOS...

In recent decades, forest nurseries in eastern Canada have been faced with periods of mild winter weather, delayed snowfall, and low seedling protective snow cover combined rains instead snowfall. These extreme conditions resulted the loss millions seedlings, particular those that overwinter outdoors, probably due to their dehardening. The main objective this study is simulate different warm we...

In forests, the growth and productivity of individual trees stands as a whole are regulated by stand density among other factors, because access to vital resources is limited competition between trees. On 18 experimental plots Scots pine (Pinus sylvestris L.) planted with 500–128,000 trees/ha in south taiga (Middle Siberia), interactions density, tree- stand-scale productivity, tree-ring parame...

The sandstones which constitute the host rock for prehistoric artwork in Rock Groups of Tajo de las Figuras and Peñas Cabrera (southern Spain) show a serious degree alteration, due both to natural processes those related anthropogenic animal activity. A detailed study was carried out on petrological compositional characteristics (fresh altered rock) groups, geological climatological area they a...
