An annotated list of nematodes recovered from 35 species of Turkish vertebrates is presented. In addition to information enabling improved taxonomic characterization of several species, the annotations describe Heligmosomum sp., a parasite of Crocidura russula, and discuss the value of the dorsal ray in distinguishing between species of the Heligmosomidae. Observations are made on the parasitic stages in the life history of Angusticaecum holopterum and their distribution in the host. Notes are given on the recognition of the genus Pseudophysaloptera, and the male of Rictularia proni is described.

1. The life history of N. battus is described, and a comparative description of the life history of N. filicollis is given.2. The life histories of these two species are compared with those of N. spathiger and N. helvetianus, two closely related species, and are shown to follow the same basic pattern, with minor variations in timing which appear to be specific in nature, and not related to differences in culture methods or host species.3. The pathogenesis of Nematodirus species is discussed and related to the migration of larvae into the intestinal mucosa during development.

Seymouria is the best known of the seymouriamorphs, a group of Permo-Carboniferous reptiliomorphs with both terrestrial and aquatic taxa. The majority of research on Seymouria has focused on cranial anatomy, with few detailed descriptions or illustrations of the postcrania. We utilized neutron computed tomography (nCT) and histological sampling to provide updated, detailed figures that clarify details of the postcranial anatomy and to assess the development and histology of Seymouria through specimens from the early Permian Richards Spur locality. The correlation of morphological and histological data indicate rapid metamorphosis in this terrestrially capable stem amniote, with the youngest specimen being postmetamorphic despite being distinctly younger than premetamorphic individuals of Discosauriscus, the only other seymouriamorph to have been histologically sampled. The microanatomical data (e.g., semi-open medullary cavity) also substantiate the hypothesis that Seymouria was terrestrial based on interpretation of external features, although the persistence of a modestly developed medullary spongiosa in comparison to either Discosauriscus or to other co-occurring terrestrial tetrapods suggests additional nuances that require further exploration. In the absence of clearly recognizable postmetamorphic stages in several seymouriamorph taxa, it is difficult to determine the evolutionary trajectory of terrestriality within the clade. Our analysis provides the first histological characterization of the life history of Seymouria and highlights the need for further study of seymouriamorph ontogeny.

Abstract Clonal reproduction of lianas is a common but important life history strategy. It is necessary to evaluate the clonal structure of liana species because clonal ability is potentially a major determinants distribution pattern of lianas. Therefore, we developed 10 microsatellite markers for Euonymus fortunei and Schizophragma hydrangeoides respectively from genomic sequences obtained from double-digest restriction site associated DNA (ddRAD). The sequence data of the developed markers were deposited on the public database. The expected heterozygosity (HE) of E. fortunei and S. hydrangeoides ranged from 0.727 to 0.847 with an average of 0.766, and from 0.734 to 0.924 with an average of 0.812, respectively. All loci were under HWE except for a locus of S. hydrangeoides (sh07). These markers should contribute to the understanding of the life history of temperate liana species.

Eight yeast strains (denoted as D1 to D8) were isolated from samples of natural fermented pineapple. Strain D8 showed highest alcoholic production at low pH and special aroma of pineapple has been chosen for further study. Taxonomic characterization of strain D8 using morphological, biochemical and molecular biological studies confirmed that strain D8  belong to Saccharomycetaceae family, Saccharomycetales order and Saccharomyces cerevisiae species. Therefore, we named this strain as Saccharomyces cerevisiae D8 for further study on Brandy production from pineapple. Citation: Hoang Thi Le Thuong, Nguyen Quang Hao, Tran Thi Thuy, 2017.
