The red alga Compsopogon caeruleus can generally be found in tropical and subtropical waters worldwide. In addition to its natural habitats, this species may that receive abnormally hot water, e.g., from powerhouses. To date, the presence of C. has not been observed thermally polluted lacustrine ecosystems Poland, which a moderate climate. thalli were growing on Vallisneria spiralis Licheńskie ...
Glutamine synthetase (GS) is encoded by three distinct gene families (GSI, GSII, and GSIII) that are broadly distributed among the three domains of life. Previous studies established that GSII and GSIII isoenzymes were expressed in diatoms; however, less is known about the distribution and evolution of the gene families in other chromalveolate lineages. Thus, GSII cDNA sequences were isolated f...
یک جلبک قرمز آب شیرین به نام Compsopogon caeruleus برای اولین بار از کانال آب جاری در جنوب تهران جمعآوری شد. این گیاهان به طور اپیفیت روی جلبک سبز Cladophora sp. در کانال آب جاری سرد در دمای°C 10-8 و سرعت زیاد در عمق cm 50-30 زندگی میکردند. تال رشتهای ماکروسکوپی، خاکستری تا سبز مایل به خاکستری، در فصل رشد به فراوانی منشعب شده هستند. انشعابات با محور اصلی، زاویه حاده (حدود° 70-20) می سازند. ...
Mitochondrial DNA (mtDNA) from 25 blue tits Parus caeruleus sampled from two populations of the Grenoble region (France) was assayed for polymorphism with 17 restriction endonucleases. Nine genotypes were found. Several mtDNA genotypes were also analysed by amplification via the polymerase chain reaction (PCR) and direct sequencing of 903 bp of the cytochrome b gene. The mtDNA polymorphism is g...
Fish as natural predators of mosquito larvae is a way controlling biologically that does not pose risk to the health organisms and environmental damage overcoming problem resistance chemical larvacide. One fish tested in study was rosy barb (Pethia conchonius) lemon cichlid (Labidochromis caeruleus). Objectives: To analyzed difference predation ability male female larvae. Methods: This an exper...
We compared heavy metal levels, calcium levels, breeding parameters and condition of nestling and adult Cyanistes caeruleus and Parus major along a heavy metal pollution gradient. Both species started laying earlier and showed inferior nestling growth and smaller fledging probability in the polluted areas, which are phenologically advanced in spring due to sparse forests. The major inter-specif...
In 2009 Phaeobacter caeruleus was described as a novel species affiliated with the marine Roseobacter clade, which, in turn, belongs to the class Alphaproteobacteria. The genus Phaeobacter is well known for members that produce various secondary metabolites. Here we report of putative quorum sensing systems, based on the finding of six N-acyl-homoserine lactone synthetases, and show that the bl...
