New Concept of Animal Underpass - Green Bridge

In Poland, the ecological corridor map overlaps with forests, as well as with the road network. The police have recorded near a 100% increase in animal mortality over the last decade. In most cases, bridges automatically serve as passages for animals, even if they have not been considered and designed for such a role. The following facts are importand: silence is positive for animals, natural guides are better then fences and walls, gentle lighting moderates car lights at night. Therefore, the semi-transparent canopy-type noise screens should be used, as well as olfactory tracks. The solution proposed here is beneficial for both the environment and road users. For the proper functioning of the bridge, it is crucial to take into consideration that animals are more efficiently guided by their smell than by channelling fences. However, the commonly used fences would also be provided. Olfactory traces can come in two kinds: animal faecal matter and mating scents. In a natural habitat, decreasing the immediate proximity between animals and humans should also be considered. A multi-criteria analysis was conducted to prove benefits both in terms of bridge maintenance effort and the impact on the environment. The criteria were selected on the basis of expert opinions.

A REVIEW ON WHEAT STREAK MOSAIC VIRUS (WSMV) DISEASE COMPLEX

Wheat is one of the most important staple food crop .Wheat streak mosaic virus (WSMV) was first time reported in Nebraska in 1922 as "yellow mosaic". Since then, although sporadic in its appearance and severity, wheat streak mosaic has caused losses throughout North America, Europe, North Africa and Russia. The disease was probably present in other counties, but was not detected. WSM symptoms are characterized by a yellow leaf streaking or stippled pattern and stunting, head sterility, low test weights, and poor tillering and it is a seed born or mite born disease.WSMV is transmitted by eriophyid mite in both semi persistent and circulative manners. Mostly WSMV infects the crops belonging to family graminae or Poaceae (wheat, barley) and other alternate host of the WSMV are the grassy weeds or green bridge where wheat curl mite (WCM) over winters and lay eggs in the absents of the host. Wheat production in the Great Plains is also threatened by the newly discovered wheat viruses including Wheat mosaic virus and Triticum mosaic virus (TriMV). Both viruses closely match the life cycle of WSMV and are transmitted by WCM. Genome of WSMV contains positive sense ssRNA virions and one polyprotein. The tritimovirus which is approximately of 10kb in size

TILTAI IR KELTAI KAIP XVIII AMŽIAUS VILNIAUS PAVIETO BAJORŲ TEISINIŲ GINČŲ OBJEKTAI IR NUSIKALTIMŲ ERDVĖS

Bridges and ferries, as objects of dispute and crime locations among the eighteenth century nobles of Vilnius district, is the main topic of research in this article. Case materials and auxiliary documents from the records of Vilnius district castle and land courts reveal how often bridges are mentioned in the court processes in both violent and non-violent crimes. Research explores what types of violent crimes took place on bridges or ferries most often. It also works on questions of geographic localisation and statistics, discussing general situation of bridges in Vilnius and its neighbouring areas in the eighteenth century. Bridges are regularly mentioned in the books of the eighteenth century Vilnius castle and land courts, albeit most references are not related to conflicts and bridges are mentioned as orientation marks or in reference to location of a real estate object. Both non-violent legal disputes, involving bridges as objects, and violent crimes on the bridges were not in multitude, however non-violent crimes were in smaller numbers. There were seven dispute cases about lands, properties and plots of land where bridges and ferries are mentioned. Non-violent conflicts mostly took place in rural areas of the district, four of them, and three such disputes happened in Vilnius (one on the Green Bridge and two on the bridges over the River Vilnia). Most commonly recorded violent crime on a bridge was beating and, since this was the most common type of crime perpetrated by nobles in the eighteenth century Vilnius district, this trend is logical. A bridge is once mentioned in the record about a raid. In terms of location, more crimes on the bridges took place in the rural space, although this particular space wasn’t dominant, since six crimes were reported in the province and five in the city – two in Vilnius on the Green (Stone) Bridge, two on the bridges over the River Vilnia and one on a ferry near Šnipiškės. Trends in crime locations match general crime tendencies in Vilnius district, where more crimes took place in the rural space than in the urban one. One may guess, that the rare mention of bridges partially testifies to the fact that in the eighteenth century Vilnius district level of communication was not high and there were not too many bridges. On the other hand, when assessing trends in violent crimes in Vilnius district it was revealed that bridge based crimes comprised only one percent of all crimes. Having in mind that bridge is a relatively small object, compared to several different or other urban and rural spaces, this number isn’t that small. Keywords: Vilnius district, castle court, land court, crimes, nobles, peasants, bridges, ferries, passings.

Characterizing and Mapping Resistance in Synthetic-Derived Wheat to Rhizoctonia Root Rot in a Green Bridge Environment

Root rot caused by Rhizoctonia spp. is an economically important soilborne disease of spring-planted wheat in growing regions of the Pacific Northwest (PNW). The main method of controlling the disease currently is through tillage, which deters farmers from adopting the benefits of minimal tillage. Genetic resistance to this disease would provide an economic and environmentally sustainable resource for farmers. In this study, a collection of synthetic-derived genotypes was screened in high-inoculum and low-inoculum field environments. Six genotypes were found to have varying levels of resistance and tolerance to Rhizoctonia root rot. One of the lines, SPBC-3104 (‘Vorobey’), exhibited good tolerance in the field and was crossed to susceptible PNW-adapted ‘Louise’ to examine the inheritance of the trait. A population of 190 BC1-derived recombinant inbred lines was assessed in two field green bridge environments and in soils artificially infested with Rhizoctonia solani AG8. Genotyping by sequencing and composite interval mapping identified three quantitative trait loci (QTL) controlling tolerance. Beneficial alleles of all three QTL were contributed by the synthetic-derived genotype SPCB-3104.

Timing of Glyphosate Applications to Wheat Cover Crops to Reduce Onion Stunting Caused by Rhizoctonia solani

Stunting caused by Rhizoctonia spp. is economically important in irrigated onion bulb crops in the semiarid Columbia Basin of Oregon and Washington, where cereal winter cover crops commonly are planted the previous fall to prevent wind erosion of soil. The cover crop is killed with herbicide application just before or shortly after onion seeding, so that the dead rows of cereal plants provide a physical barrier tall enough to protect onion seedlings against wind and sand blasting but not tall enough to shade onion seedlings. However, the cover crop also serves as a green bridge for Rhizoctonia spp. on cereal roots to colonize the onion roots, potentially resulting in severe stunting of onion seedlings. To determine the effect of timing of application of the herbicide glyphosate to reduce this green bridge effect and, subsequently, onion stunting, three herbicide application intervals preceding onion planting were evaluated in a grower’s onion field in each of 2012 and 2014 in the Columbia Basin. The wheat cover crop was killed with a glyphosate application 27, 17, and 3 days before onion seeding in 2012 and 19, 10, and 3 days before seeding in 2014. As the interval between herbicide application and onion planting increased from 3 days to 19 and 27 days, the number of patches of stunted onion plants decreased by ≥55%, total area of stunted patches decreased by 54 to 63%, and patch severity index decreased by 59 to 65%. Similarly, the Rhizoctonia solani AG 8 DNA concentration in soil sampled from the dead cover crop rows declined as the interval between glyphosate application and onion seeding increased in the 2012 trial but not in the 2014 trial. R. solani AG 3 and AG 8 DNA concentrations in soil sampled from the cover crop rows were significantly positively correlated with the number of patches of stunted onion plants (r = 0.490 and 0.607 at P = 0.039 and 0.008, respectively), total area of stunted patches (r = 0.496 and 0.659 at P = 0.035 and 0.003, respectively), and patch severity index (r = 0.492 and 0.635 at P = 0.038 and 0.005, respectively) in the 2012 trial; however, these variables were only correlated significantly with R. solani AG 3 DNA concentration in the 2014 trial. Increasing the interval between herbicide application to the cover crop and onion planting provides a practical management tool for stunting in onion bulb crops.
