Ixodes scapularis Say 1821, the primary vector of several human pathogens in the northeastern and upper Midwestern United States, has considerable genetic and morphological variation throughout its range. Recently, developmental or teratological abnormalities have been observed in this species for the first time, further complicating morphological identification. Here, we report the first evide...

The representation of morphological structures in the mental lexicon constitutes the inevitable topic in the investigation of cognitive aspects of the language data processing. In the present paper the influence of the noun case functions of the phoneme identification in Croatian language is investigated within the framework of the spoken word recognition. By means of the gating paradigm 36 sub...

The understanding of malaria vector species in association with their bionomic traits is vital for targeting malaria interventions and measuring effectiveness. Many entomological studies rely on morphological identification of mosquitoes, limiting recognition to visually distinct species/species groups. Anopheles species assignments based on ribosomal DNA ITS2 and mitochondrial DNA COI were com...

Morphological and molecular characterization of twenty six landraces rice and four high yielding rice accessions were studied to observe genetic diversity assessment and identification of superior genotypes for crop improvement program. Fourteen morphological and twenty seven DNA based molecular markers, simple sequence repeat (SSR), were used extensively to carry out this study. A wide range o...

background: accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. however, due to a close morphological similarity between the eggs and larval stages of many of these nematodes,such identification is not a trivial task. there are a number of studies showing that molecular targets in ribosomal dna (internal transcri...

Morphological variation in three rarely collected European species of the genus Lasiochernes Beier, 1932 is thoroughly examined in the present study. Detailed descriptions of previously ignored morphological characters of Lasiochernes cretonatus Henderickx, 1998, Lasiochernes jonicus (Beier, 1929) and Lasiochernes pilosus (Ellingsen, 1910) are presented. The female of Lasiochernes cretonatus an...

The specific identification of Lymnaeid snails is based on a comparison of morphological characters of the shell, radula, renal and reproductive organs. However, the identification is complicated by dissection process, intra and interspecific similarity and variability of morphological characters. In the present study, polymerase chain reaction and restriction fragment length polymorphism (PCR-...
