quantifying morphological characteristics of body shape in fishes can help their correct identification as well as understanding of evolutionary history of their different populations. hence, this study was aimed to compare the morphological characteristics of different population of tuini fish (capoeta damascina) in inland-water of iran using geometic morphometrics method (gm). in total 373 sp...

Aeromonas infections are the most common bacterial disease of cultured fish in China. In this study, a gram-negative bacillus was isolated from the liver of diseased koi carp (Cyprinus carpio koi), and named strain KC-2. The results of morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and gyrB sequences indicated that the isolated strain KC-2 was highly...

Large and diverse genera, such as Silene need more reliable morphological traits for the credible identification and delimitation of the species. Despite the fact that the type of indumentum among the species of Silene had been addressed in most available revisions, monographs and floristic studies, the trichome-based features and their adaptational importance have not been investigated explici...

The last 40 years have witnessed a growing interest in the mechanisms underlying the visual identification of complex words. A large amount of experimental data has been amassed, but although a growing number of studies are proposing explicit theoretical models for their data, no comprehensive theory has gained substantial agreement among scholars in the field. We believe that this is due, at l...

The taxonomy of fungal species, similar to that of many other microorganisms, suffers frequent revisions due to the discovery of new species and to the development and gathering of characterization data and morphological information. Morpho-taxonomy helps in the identification of many species. This work presents the macro, micro-morphological, and spectral mass analyses for phenotypic character...

This thesis explores the computational structure of morphological paradigms from the perspective of unsupervised learning. Three topics are studied: (i) stem identification, (ii) paradigmatic similarity, and (iii) paradigm induction. All the three topics progress in terms of the scope of data in question. The first and second topics explore structure when morphological paradigms are given, firs...

Identification of general properties of evolutionary radiations has been hindered by the lack of a general statistical and phylogenetic approach applicable across diverse taxa. We present a comparative analytical framework for examining phylogenetic patterns of diversification and morphological disparity with data from four iguanian-lizard taxa that exhibit substantially different patterns of e...

Tetragonula biroi Friese, the most popular stingless bee species in Philippines, belongs to Tetragonula, a difficult genus deal with due high character variability of workers. This paper provides detailed description morphological characters, nest features, and behavioral characteristics T. help facilitate its classification identification. Proper identification bees is crucial biodiversity con...

Molecular species identification is becoming more wide-spread in diagnostics and ecological studies, particularly with regard to insects for which morphological identification is difficult or time-consuming. In this study, we describe the development and application of a single-step multiplex PCR for the identification of three mealybug species (Hemiptera: Pseudococcidae) associated with grapev...

Morphological description of sand,flies has remained a neglected area. The different organs used in taxonomy have not yet been described adequatelAy with the scanning electron microscopy (SEM). We have examined the external genital structures offemales of three Old World phlebotomine sand,flies under SEMand recorded the morphological variations of the organs. We have,found the,female external g...
