Hyperspectral imaging offers enormous potential for measuring grape composition with a high degree of representativity, allowing all exposed grapes from the cluster to be examined non-destructively. On-the-go hyperspectral images were acquired using push broom camera (400–100 nm) that was mounted in front part motorized platform moving at 5 km/h commercial Tempranillo vineyard La Rioja, Spain. ...

The thermal time, expressed in accumulated growing degree-days (AGDD), was used as a predictor to describe and simulate the independent growth of two pasture crops, Lolium perenne L. Bromus valdivianus Phil. Two sinusoidal models (four-parameter Logistic Gompertz) were applied variables (total leaf blade length per tiller—LBL, herbage mass—AHM). nutritive value pastures predicted modeled using ...

Urban nature reserves in Poland are precious relics of ancient with preserved biodiversity. They consist valuable trees several 100 years old, biodiverse, and recreational spaces right around cities. It is therefore critical to manage tradeoffs between visitor safety due to, e.g., falling dead branches the need for old-grown biodiversity conservation. This study aimed determine whether airborne...

Information on industrial hemp (Cannabis sativa) water use and stress is sparse. We studied impact in two essential-oil cultivars (‘Wife’ ‘Cherry’) prompted by anecdotal differences growth use. In a greenhouse setting, we measured relations, use, growth, essential oil (CBD-cannabidiol THC-delta-9 tetrahydrocannabinol) concentrations. Water did not significantly affect THC CBD concentrations, bu...

The species of pear sucker, also called psylla or psyllid, which are destructive insects belonging to the genus Cacopsylla (Hemiptera: Psyllidae) cause substantial damage tree plantations. Two consecutive years research were conducted on population structure and biological cycle in a small, elderly, unmaintained orchard northern Romania. Of two identified (C. pyri L. C. pyricola Forster), domin...

With climate change projected to increase the frequency and severity of episodic insect outbreak events, assessing potential consequences for soil microbial communities nutrient dynamics is importance understanding forest resilience. The tent caterpillar (Malacosoma disstria) an important defoliator deciduous tree species in temperate mixed forests eastern North America with invasion cycle ever...

The current increase of severe droughts associated with climate change is one the main causes observed dieback in Mediterranean holm-oak ( Quercus Ilex subs ballota ) forests. Effects forest soils are greatly variable and depend on a number local factors, but generally include increased soil organic C due to litter inputs, alterations nutrient contents, changes nitrogen cycle, detrimental effec...

Natural grasslands are an important renewable resource for livestock production. Grazing in these areas alters the plant community composition, litter quality, and soil microbial structure activity. Three cool-season species were studied a semiarid rangeland area of Argentina: Poa ligularis Nassella tenuis (desirable/preferred livestock) Amelichloa ambigua (undesirable/non preferred). The objec...

This research is dedicated to solving an urgent problem associated with the large-scale destruction of taiga forests by Siberian silk moth (Dendrolimus sibiricus) outbreaks. The dynamics damage dark coniferous forest stands induced outbreaks in mid-altitude mountains were studied. A hypothesis was formulated based on fundamental influence orography phytophage’s dispersal within landscape, along...
