It is assumed that the abundance of Agriotes wireworms (Coleoptera: Elateridae) is affected by agro-ecological factors such as climatic and edaphic factors and the crop/previous crop grown at the sites investigated. The aim of this study, conducted in three different geographic counties in Croatia from 2007 to 2009, was to determine the factors that influence the abundance of adult click beetle...

High concentrations of metals in organic matter can inhibit decomposition and limit nutrient availability in ecosystems, but the long-term fate of metals bound to forest litter is poorly understood. Controlled experiments indicate that during the first few years of litter decay, Al, Fe, Pb, and other metals that form stable complexes with organic matter are naturally enriched by several hundred...

The objective of this study was to determine ecology of Clostridium botulinum from previous reported outbreaks. Geographical parameters and their corresponding settings were collected and analyzed. The averages (mean +/- SD) for % soil moisture, % humus and pH were 0.6 +/- 0.1% (range 0.5-0.7), 3.0 +/- 0.2% (range 3-3.2) and 5.2 +/- 0.1 (range 5.1-5.4), respectively. All outbreak settings share...

We examine the hypothesis of an increase of humus disintegration by analyzing chemical substances measured in the seepage water of a German forest. Problems arise because of a large percentage of missing observations. We use a regression model with spatial and temporal effects constructed in an exploratory data analysis. Spatial dependencies are modelled by random effects and an autoregressive ...

This communication presents preliminary results of studies on the mite fauna observed in the spruce stands of the Bucegi Massif in central Romania. In the collected material a total of 6436 specimens were found, which were classified to 62 species from 15 families. The most numerous were the species Veigaia nemorensis (1660 individuals), Leptogamasus parvulus (804) and Leptogamasus tectegynellu...

One of the most important properties soil is its fertility, which formed in process formation and characterized by totality all indicators. Restoration fertility preservation should be a priority task modern agriculture, as it one reserves for increasing production agricultural products. The purpose research was to determine dependence sunflower productivity on physico-chemical agrochemical par...
