The potential of different bacterial-feeding Rhabditida to consume isolates of Burkholderia cepacia with known agricultural biocontrol ability was examined. Caenorhabditis elegans, Diploscapter sp., Oscheius myriophila, Pelodera strongyloides, Pristionchus pacificus, Zeldia punctata, Panagrellus redivivus, and Distolabrellus veechi were tested for growth on and preference for Escherichia coli O...

Serratula L. and Klasea Cass. are two systematically related genera of the family Asteraceae, which distributed in most Eurasia area used as food colorants traditional medicines a drug. Since 1967, 261 metabolites have been isolated identified from five species 21 species. This review provides information on chemodiversity terpenes, penolics, lipids, other compounds found both their occurrence ...

Chromosome numbers of eleven angiosperm species, five dicots and six monocots from Georgia and Azerbaijan are reported. The chromosome number of Cruciata coronata (Rubiaceae) is provided for the first time (2n = 22). Additionally, karyotypes are presented for five species, those of Danae racemosa (Ruscaceae), Paris incompleta (Trilliaceae), and Ruscus hyrcanus (Ruscaceae) for the first time. Th...

Using genetic data to study the process of population divergence is central to understanding speciation, yet distinguishing between recent divergence and introgressive hybridization is challenging. In a previous study on the phylogeography of the yellow-rumped warbler complex using mitochondrial (mt)DNA data, we reported limited sequence divergence and a lack of reciprocal monophyly between myr...

The Chinese species of the silphaeformis group of the genus Tachinus Gravenhorst are revised with fifteen species being treated. Thirteen of them are described as new: T. armatus Feng & Li, sp. n. (Sichuan), T. cavazzutii Feng, Li & Schülke, sp. n. (Sichuan), T. coronatus Feng, Li & Schülke, sp. n. (Ningxia, Qinghai), T. hercules Feng, Li & Schülke, sp. n. (Sichuan), T. hujiayaoi Feng, Li & Sch...

In many benthic organisms with a planktonic larval stage, local populations have different morphology. Such difference may arise from some of the following proximate mechanisms. "Local recruitment (LR)": no larvae move between local populations, and segregated populations possess alleles coding for locally adaptive morphology. "Intragenerational selection (IS)": larvae move between local popula...

C. elegans is a member of a group of nematodes called rhabditids, which encompasses a large number of ecologically and genetically diverse species. A new, preliminary phylogenetic analysis is presented for concatenated sequences of three nuclear genes for 48 rhabditid and diplogastrid species (including 10 Caenorhabditis species), as well as four species representing the outgroup. Although many...

Phytoecdysteroids exert significant anti-inflammatory effects, which makes them valuable ingredients in pharmaceutical and cosmetic products. However, data on their use cosmetics are limited. Here, a new formulation with the extract of Serratula coronata herb containing phytoecdysteroids was developed. The aim this study to perform physicochemical characteristics evaluate safety creams S. coron...

The Australian harvestmen genus Megalopsalis (Neopilionidae: Enantiobuninae) is recognised as a senior synonym of the genera Spinicrus and Hypomegalopsalis, and seven new species are described in Megalopsalis: Megalopsalis suffugiens, Megalopsalis walpolensis, Megalopsalis caeruleomontium, Megalopsalis atrocidiana, Megalopsalis coronata, Megalopsalis puerilis and Megalopsalis sublucens. A morph...
