Protists have traditionally been identified by cultivation and classified taxonomically based on their cellular morphologies and behavior. In the past decade, however, many novel protist taxa have been identified using cultivation independent ssu rRNA sequence surveys. New rRNA "phylotypes" from uncultivated eukaryotes have no connection to the wealth of prior morphological descriptions of prot...

Metagenomics has provided access to genomes of as yet uncultivated microorganisms in natural environments, yet there are gaps in our knowledge-particularly for Archaea-that occur at relatively low abundance and in extreme environments. Ultrasmall cells (<500 nm in diameter) from lineages without cultivated representatives that branch near the crenarchaeal/euryarchaeal divide have been detected ...

The aim of this paper is to define and quantify environmental indicators for farmland habitat in Italy. Based on OECD works and recent developments by the Joint Working Party in the area of agrienvironmental indicators, we classify agricultural habitat in three main categories: intensive, semi-natural and uncultivated (natural or man-made) habitats located within, at the border and adjacent of ...

Grazing businesses with a proportion of native grassland may face the choice of reassigning the rights to use an area of native grassland to the public. In analysing this choice it is important to establish the future situation of the farm business with and without the area of land in question, including the possibility of further development of production capacity on other areas of the farm. T...

Methane-oxidizing bacteria are characterized by their capability to grow on methane as sole source of carbon and energy. Cultivation-dependent and -independent methods have revealed that this functional guild of bacteria comprises a substantial diversity of organisms. In particular the use of cultivation-independent methods targeting a subunit of the particulate methane monooxygenase (pmoA) as ...

Over a third of oral bacteria are as-yet-uncultivated in-vitro. Siderophores have been previously shown to enable in-vitro growth of previously uncultivated bacteria. The objective of this study was to cultivate novel oral bacteria in siderophore-supplemented culture media. Various compounds with siderophore activity, including pyoverdines-Fe-complex, desferricoprogen and salicylic acid, were f...

A new theoretical approach is proposed to predict a practical upper limit to the efficiency of a very large wind farm. The new theory suggests that the efficiency of ideal turbines in an ideal very large wind farm depends primarily on a non-dimensional parameter λ/Cf0, where λ is the ratio of the rotor swept area to the land area (for each turbine) and Cf0 is a natural friction coefficient obse...

We carried out a quantitative assessment of the consumption of herbaceous plants by Opatrumsabulosum (Linnaeus, 1761) - a highly significant agricultural pest species. We researched the feeding preferences of this pest species with respect to 33 uncultivated and 22 cultivated plant species. This species of darkling beetle feeds on many uncultivated plant species, including those with hairy leav...
