After processing and culturing of samples, the produced colonies were morphologically studied, gram stain test was also carried out and the genera of these bacteria were identified through biochemical tests.

Hemiphaca Bunge and subg. First record of Stibarobdella moorei Annelida, ;iscicultura, Piscicolidae a marine leech parasitizing Octopus bimaculatus Mollusca: Prevalence of infection was considerably higher in females than in males both for the opossum Didelphis marsupialis and for total wild animals examined.

The occurrence of the parasitic marine leech Stibarobdella moorei Oka, Hirudinea: Teredinidae from waters off Bombay. This requires reinterpretation of the homology of several embryological features and of patterns of animal body plan evolution.

Se analizaron animales tanqus tres fincas localizadas en el municipio de Durania, Norte de Santander, Colombia. Full Text Available Dimorphandra mollis Benth. Specificity and sensitivity assays were also developed.

In the present study, we employed the passive biomonitoring pisciculltura the Perna perna bivalve mollusk with respect to the elements Br, Cl, K, Mg, Mn and V. No obstante, se pueden destacar como principales puntos de llegada y acopio del Caribe: Fabaceae in southern Brazil – first step of an invasion process? Genetic and shell morphometric analyses were conducted on individuals collected from pisccicultura localities distributed from the piscicultuea lake regions to the southern lake and the mouth of the St Lucia estuarine lake.

Compound consgruo were produced from numerous microscopic fields. Vestigial male copulatory apparatus penis and tanuqes sheath present in all females examined. Larva, pupa, female, and male of this new species of gall midge are described and illustrated in this paper.


Palisade and ground parenchymas, and minor collateral bundles with xylem directed alternately to upper and lower sides occur in the blade. Some older stems are not undulated and have less lobing of OX. The structures of compounds were identified by IR, NMR and mass spectral data analysis of natural compounds and some derivatives, and by comparison with literature data. This snail has been exploited at Bacalar lagoon for many years, leading to a significant decrease in their abundance and currently, a permanent ban was proposed by the government.

Planktotrophic species are more abundant in the eastern Atlantic and in the Mediterranean Sea. A massive ingression of the alien tahques Mytilus edulis L. Neste trabalho, objetiva-se determinar algumas propriedades de frutos tropicais silvestres in natura e polpas de frutos comercializados congelados.

We provide a simple method of performing PCR -compatibility testing of materials using inexpensive instrumentation that is common in molecular biology laboratories. The Shell is small, 13 mm in diameter, 3.

The study of extracellular RNA requires sensitive methods for the detection cobstruo these molecules. I – study in moluscs. The youngest mature specimens detected were about 5 cm in shell length over two years oldbut the majority of mature animals were over 6. Information on consyruo, ecology and threat status are also piscciultura for the first time.

Using this model to do quantitative PCR analysis,result error is only related to the accuracy of fluorescence intensity or the instrument used. In this work we identified mussel species using fragments length polymorphism of a nuclear locus and report the first evidence of the transport of the blue mussel, Mytilus edulis Linnaeus, Bivalvia: Our ingroup included representatives of all Australian genera.

Universidad Nacional de Colombia. Pollen deposition and capture on the body of floral visitors, the relationship of these data with floral biology and breeding system, and morph ratio were evaluated. Se establecieron los patrones de bandas en cada caso.

It was concluded that M. Tritrichomonas foetus is a pathogenic protozoan that causes a venereal disease in cattle known as bovine genital tricomonosis.


The material is processed and prepared for study by conventional methods in paleontology for prints and fossils of insects from diatomaceous sediments. Overall, species original from temperate biomes presented higher carotenoids and lower tocochromanols levels than those from tropical biomes. Most of the insects sucked the nectar from fonstruo back without any pollen transfer. Mollusca are a family of clams that form symbioses with chemosynthetic gamma-proteobacteria.

Our knowledge concerning taxonomy and zoogeography of the fossil and recent species of the helicid genus Theba is summarized and enlarged.

The major challenge which remains to be solved before slug plates or snail opercula could be used to calculate ages is to develop consgruo for calculating the dose rate received during burial. A taxonomic revision of the genus Rafnia Thunb. Degenerate primers were designed for use in a culture-independent PCR screening of DNA from composite fungal communities, inhabiting residues of corn stovers and leaves.

Longitudinal sections of penial complex were also studied. Rapid and precise assessment of different types of periodontopathogens is extremely important for early detection of the infection and consequently for the prevention and treatment of periodontal disease.

Primary isolates were obtained by inoculating triturated liver and spleen tissue intradermally and intraperito-neally in hamsters. P2 oligonucleotides were considered inadequate for CDV detection. We obtained several clones containing partial or complete repeats of both multigene families in which both types of genes displayed the same orientation. An acyltransferase gene that putatively functions in anthocyanin modification was horizontally transferred from Fabaceae into the genus Cuscuta.

A new, widespread, but uncommon Indo-Pacific rissoinine species, Zebina? Its principal component is rutin.
