  Chaetognatha are a phylum of marine carnivorous animals which includes more than extant species. The internal systematics of this group have been intensively debated since it was discovered in the 18th century. While they can be traced back to the earlier Cambrian, they are an extraordinarily homogeneous phylum at the morphological level - a fascinating characteristic that . Phylogenetic study, aided with controlled intra- and inter-species crosses, also helped to resolve taxonomic problems in the genus Paramacrobiotus (Stec et al., ), and three studies on the species-rich and taxonomically challenging Pseudechiniscus contributed to the clarification of the relationships within this heterotardigrade genus.

In this study, the new freshwater diatom species Entomoneis triundulata sp. nov. is described based on a detailed morphological observation using light and scanning electron microscopy. The specific features of E. triundulata are its triundulate valve margin; the shape of the transition between keel and valve body having a proximal U-shaped end. Recent comprehensive studies of the Hypocreales and Diaporthales using both morphological and molecular characters present the opportunity to integrate the mitotic fungi and to evaluate character evolution of both teleomorphic and anamorphic states. The majority of plant-associated fungi are mitotic species without any known.

Profª. Dra. Visitación Teresa Dora Conforti de Marconi (born ) is an Argentine biologist, algologist, botanist, taxonomist and ecologist. She is a professor in the Department of Biodiversity and Experimental Biology in the University of Buenos Aires in Buenos Aires. She is noted for her numerous taxonomic studies of Euglenophyta, including in polluted rivers in Argentina. Sun and shade leaves of Quercus velutina Lam. were evaluated with respect to differences in gross anatomy, morphology, and cuticle (cuticular membrane [CM]) ultrastructure and micromorphology. Sun leaves are smaller, with more deeply lobed margins, and have more stomata, thicker mesophylls, and thicker CMs when compared with shade leaves.

Case review studies have shown that this organism can be isolated from 33% to 77% of horses with keratomycosis and 2% to 22% of eyes from horses with external eye disease. 17 Fusarium spp. are also encountered frequently (10 of 39 horses [26%] with keratomycosis in one study 32), whereas Alternaria, Cladosporium, Pseudallescheria.

Previous studies have suggested that exuviae can be used for the identification of cicada species, but the precise characteristics that differ among species have not been determined. Thus, we performed the first comparative analyses of the leg morphology, ultrastructure, and mitochondrial DNA sequences of exuviae of four dominant cicada species in Korea, Hyalessa maculaticollis (Motschulsky Cited by: 1.

Even though morphological and phylogenetic studies suggest that Neonectria/Cylindrocarpon represents more than one genus (Samuels & BrayfordMantiri et al.Brayford et al.Halleen et al.Hirooka et al.Castlebury et al.Halleen et al.

), formal taxonomic segregation of these groups has not been by: This study investigated phylogenetic divergence, morphological difference, and pathogenic variation among Cylindrocarpon species isolates associated with black foot disease of grapevine (Vitis sp.) in California.

To assess phylogenetic divergence, we sequenced the internal transcribed spacer (ITS) of the nuclear ribosomal DNA (rDNA), partial beta-tubulin (BT) gene introns and exons, and the. This is the first study to inclusively characterize a new species of Rozella with morphological, ultrastructural and molecular data.

As this is only the second Rozella species to be examined ultrastructurally, and because it is parasitic on a member of Chytridiomycota and not Blastocladiomycota, this research supports the conservative nature of Cited by: An ultrastructural study of conidia and conidiogenous cells of Scopulariopsis brevicaulis (Sacc.) Bain.

in various stages of development is presented using transmission and scanning electron. Based on morphological features, a total of 55 strains were selected for molecular studies. Based on morphological features, the strains were classified into four described Fusarium species, namely Fusarium keratoplasticum, Fusarium falciforme, FSSC 5, and Fusarium cf.

ensiforme, and one unknown phylogenetic species was introduced. Although the. The relationship of two species of Neonectria associated with beech bark canker in North America was evaluated by comparing isolates of these and additional species of the Neonectria coccinea (Pers.:Fr.) Rossman & Samuels group found on regions in the translation elongation factor 1-alpha (EF1-α), RNA polymerase II second largest subunit (RPB2), and β-tubulin were sequenced.

Morphological and ultrastructural studies were carried out to describe spore wall structure in Gigaspora albida. Spores at different stages of development were observed, with different wall patterns being identified during the process of spore maturation.

A small red alga was isolated into culture from rhodoliths collected on the Piauí coast, northeastern Brazil.

Molecular data from the plastid-encoded rbcL gene, combined with morphological and ultr. Lantana camara L. is a species of Verbenaceae known for its aromatic and medicinal properties. Compounds extracted from its leaves are used to treat infections of the respiratory tract and have demonstrated antimicrobial potential and repellent action to Aedes mosquitoes.

Our aim was to identify and characterize the main production sites of the biologically active substances in the leaf blades. Based on morphological studies, Giardia species have been shown to present simple structural organizations when compared to other eukaryotic cells.

Following morphological studies on G. duodenalis, the organism was found to lack a number of organelles commonly found in other eukaryotic cells including mitochondria, peroxisomes as well as a.

In the mids, it was established through transmission experiments and ultrastructural studies of sarcocysts by transmission electron microscopy (TEM) that cattle was the intermediate host of three Sarcocystis spp. using dogs, cats and humans, respectively, as definitive hosts. The cat-transmitted species with microscopic sarcocysts was initially named Sarcocystis.

Dinocysts or dinoflagellate cysts are typically 15 to µm in diameter and produced by around 15–20% of living dinoflagellates as a dormant, zygotic stage of their lifecycle, which can accumulate in the sediments as microfossils.

Organic-walled dinocysts are often resistant and made out of are also calcareous dinoflagellate cysts and siliceous dinoflagellate cysts. An emerging pattern of similarity in medical case reports led to a project to compare the phylogenetic affinities of two well-known tropical fungal opportunistic pathogens, Cylindrocarpon lichenicola and Acremonium falciforme, to members of the Fusarium solani species complex.

lichenicola and A. falciforme, despite their deviating conidial morphologies, were shown via sequencing of the. Neonectria is a cosmopolitan genus and it is, in part, defined by its link to the anamorph genus Cylindrocarpon. Neonectria has been divided into informal groups on the basis of combined morphology of anamorph and teleomorph.

Previously, Cylindrocarpon was divided into four groups defined by presence or absence of microconidia and chlamydospores. Hematological and biochemical analyses of blood can be of great importance for studying the biology of species and determining the health status of animals in both the wild and captivity.

In order to determine baseline ranges for the nose-horned viper Vipera ammodytes, we determined the blood cell morphology and measured 20 hematological and 5 biochemical variables from the blood samples. Similarly, the morphological description made in this study for the Dictyocoela obtained from Echinogammarus berilloni, which was collected from.

The field of my studies is in marine parasitology generally and in the field of fish parasites particularly, especially dangerous ones, which have a great impact on human life, especially species.

At least in the snake Natrix maura, two clearly different ependymal cell populations coexist in the ymal cells were virtually absent.

Most cells of the organ display secretory features and are in contact with the cerebrospinal fluid, blood vessels, and the leptomeninges; they release a flocculent material into the ventricle.

Indeed, the number of rooted trees (that is, those for which the common ancestor of all the species included is known) for 10 species is 34, and for 50 species .Ultrastructural studies of ovarian follicle cells and mature eggs in four sibling species in the polychaete genus Capitella have revealed distinct and consistent morphological differences that parallel in some respects the differences between the species in egg size, and embryonic and larval development.

Capitella spp. I and II are extremely similar in all respects: the follicle cells lack.An integrative redescription of Hypsibius pallidoides Pilato, Kiosya, Lisi, Inshina & Biserov, was undertaken following a reexamination of the type material and new material using high-quality light microscopy, scanning electron microscopy and methods of molecular taxonomy.

Detailed morphological investigations revealed a unique complex of characters that precluded the attribution of this.
