Babesia caballi and Theileria equi are tick-borne pathogens, etiological agents of equine piroplasmosis that affect different species of Equidae causing relevantly important direct and indirect losses. A field study was conducted to evaluate the distribution of the equine piroplasms in an area of Central-Southern Italy and to identify correlated risk factors. Serum samples of 673 asymptomatic h...

Environ. Entomol. 23(2): 211-219 ABSTRACT The first field study of a genetically altered virus in the United States was performed with an isolate of the Autographa californica nuclear polyhedrosis virus (AcMNPV), which lacks a polyhedrin gene. In the first year of the study, three applications of 7.4 x 1011 AcMNPV polyhedra containing 48% genetically altered and 52% wild-type virus particles (c...

In this study, the support vector machine (SVM) was applied and validated by using the geographic information system (GIS) in order to map landslide susceptibility. In order to test the usefulness and effectiveness of the SVM, two study areas were carefully selected: the PyeongChang and Inje areas of Gangwon Province, Korea. This is because, not only did many landslides (2098 in PyeongChang and...

Soil productivity effects nutritive quality of food plants, growth of humans and animals, and reproductive health of domestic animals. Game-range surveys sometimes poorly explained variations in wildlife populations, but classification of survey data by major soil types improved effectiveness. Our study evaluates possible health effects of lower condition and reproductive rates for wild populat...

there is an increasing demand for reliable large-scale soil datato meet the requirements of models for planning of land-usesystems, characterization of soil pollution, and prediction ofland degradation. cation exchangecapacity (cec) is among the most important soil propertiesthat are required in soil databases. this paper applied a novel method for whole-soil profile predictions of cec (to 1 m)...

the effects of dominant shrub species on soil organic matter (som), including total soil carbon (sc), total nitrogen (n) and particulate organic matter (pom) were studied in three stands differing in the type of shrub species, i.e. astragalus microcephalus (shrub), pteropyrum aucheri (shrub) and prangus uloptera (non-shrub).the stands were located in arid grasslands of north-western iran. for t...

background: the municipal waste landfill sites have high a potential of contaminating the ‎ environment and having effects of the human health due to waste degradation, production of leachate, carbon dioxide and ‎ methane gases. the present study aims to evaluate the location of the solid waste landfill using gis and based on the oleckno index. assessment parameters included average annual rain...

Abstract A new method for isolation of methane oxidising bacteria (methanotrophs) is presented. Soil samples from a wetland area and a landfill were plated on polycarbonate membranes, which were incubated in a methane-air atmosphere using a non-sterile soil suspension as the medium. The membrane acted as a permeable growth support. The membrane method resulted in selective growth conditions, wh...
