Forest fires causes and motivations are poorly understood in southern south-eastern Europe. This research aims to identify how experts perceive the different of forest as defined classification proposed by European Commission 2013. A panel (N = 271) was gathered from EU Southern Member States (France, Greece, Italy, Portugal, Spain) Central (Switzerland) Europe (Croatia, Serbia, Bosnia Herzegovina, Republic North Macedonia, Turkey). Experts were asked answer a questionnaire score importance...

In this research we search for a functional dependence between the occurrence of forest fires in USA and factors which characterize solar activity. For purpose used several methods (R/S analysis, Hurst index) to establish potential links influx some parameters from sun with lag days. We found evidence connection developed prognostic scenario based on Adaptive neuro-fuzzy interference system (ANFIS) technique. This allows prediction 79-93% fires.

Forest fires that occurred in Portugal on June 18, 2017, caused several tens of human casualties. The cause their emergence, as well many others western Europe at the same time remained unknown. Taking into account consequences, including loss lives and endangerment ecosystem sustainability, discovering forest causes is very significant question. heliocentric hypothesis has indirectly been tested, according to which charged particles are a possible fires. We must point out it was not verify...

The aim of this paper is to provide a detailed synoptic analysis severe event, waterspout, and confirm an indication that in most cases such events could potentially be forecasted, which great practical significance, since human lives property can saved. presents the research results mesoscale conditions created favourable meteorological environment for waterspout development Tivat (Montenegrin coast) on June 9, 2018,...

All over the globe, outdoor sports events are highly affected by weather conditions that frequently influence comfort of players and fans, duration, or even cancelation event. To verify range weather-induced impacts on selected Major League Baseball events, this interdisciplinary study investigated causes unexpected postponements several games in March April 2018, according to official reports event host destinations. The impact was measured a recurrent neural network with long short-term...

The impact of solar activity on environmental processes is difficult to understand and complex for empirical modeling. This study aimed establish forecast models the meteorological conditions in forest fire areas based parameters applying neural networks approach. During July August 2018, severe fires simultaneously occurred State California (USA), Portugal, Greece. Air temperature humidity data together with (integral flux protons, differential electron proton flux, wind plasma parameters,...

In this paper, the water quality of Moraca River and its main tributaries (the Zeta Cijevna) were analyzed, using Water Quality Index (WQI) methods. Data from 12 hydrological stations (HS) 2010 to 2018 used. The analysis included ten parameters physic, chemical microbiological quality: oxygen saturation, BOD5, ammonium ion, pH value, total nitrogen oxides, orthophosphates, suspended solids, temperature, electrical conductivity coliform bacteria. Calculations for all HS made Serbian (SWQI)....

Common mistletoe (Viscum album L) is a semiparasitic angiosperm, which attacks great number of broadleaf and coniferous tree species. Especially high damage caused by subspecies V. subsp. abietis, infests fir trees. This paper presents the most frequent parasitic saprophytic fungi occurring on common mistletoe. There are altogether 22 identified species, significant Botryosphaeria dothidea Gibberidea visci Sphaeropsis visci. Further study should be focused testing their potential use in biocontrol

The data on forest fires in Portugal the period 1980-2015 were used research: annual number of fires, burned area and average per fire. Increasing trend (statistically significant at p≤0.01), nonsignificant increasing decreasing fire p≤0.01) recorded. is most endangered country by comparison with other European countries. During research period, covered 23.6% total five affected countries (Portugal, Spain, France, Italy Greece). In connection between Atlantic Multidecadal Oscillation (AMO)...
