The correct identification of differentially abundant microbial taxa between experimental conditions is a methodological and computational challenge. Recent work has produced methods to deal with the high sparsity and compositionality characteristic of microbiome data, but independent benchmarks comparing these to alternatives developed for RNA-seq data analysis are lacking.

Methods for morphological identification of water frogs from the Pelophylax esculentus complex have changed over the decades. Still, without resort to genetic analyses, water frogs remain among the most difficult European amphibians to distinguish due to their hybrid nature. The aim of this study was to identify a reliable set of quantitative and qualitative morphological characters that objectively resolve species’ identification in the Pelophylax esculentus complex and provide a rapid and robust procedure for taxon identification.

The algal flora of 17 lakes and 1 pond in the Artabel Lakes Nature Park were investigated during two summer seasons (2013 and 2016). In total, 26 desmid taxa were found and identified as new records for the desmid flora of Turkey based on their morphotaxonomic characteristics and ecological preferences. The taxa identified belong to the genera Actinotaenium (1), Closterium (1), Cosmarium (15), Micrasterias (1), Spondylosium (1), Staurastrum (5), Teilingia (1), and Tetmemorus (1). Morphotaxonomy, ecology, and distribution of each species were discussed in detail.

This paper includes the morphological and anatomical characters of the nutlets of 7 endemic species of the subsection Fragiles of the genus Stachys (Lamiaceae) from Turkey and the systematic significance of these characteristics, using one-way analysis of variance and cluster and principal component analyses. Morphological characters such as the dimensions, shapes, colors, and surfaces of the nutlets were studied using light and scanning electron microscopes.

Micromorphological characteristics of 13 Trifolium species, which are grown in the province of Bolu, were examined using a scanning electron microscope (SEM). The morphological characteristics determined from the study were subjected to morphometric analyses and their variation spectrums were defined. Tricolporate pollen grains showed two pollen shapes, prolate and subprolate, according to equatorial view. The smallest size of polar axis length (18.00 μm) was found in T. micranthum Viv. from section Chronosemium Ser.; the largest (88.95 μm) was found in T. hirtum All.

Palynological characters of 20 taxa belonging to the Turkish subgenus Cyanus were studied in details using light and scanning electron microscopy. Pollen grains of the subgenus Cyanus were tricolporate or syncolporate, subprolate or prolate-spheroidal, 26.15 to 53 µm in polar size, 22.84 to 46.86 µm in equatorial size, isopolar, and radially symmetrical. The only type of pollen grain ornamentation observed was scabrate-perforate. Principal component analysis and cluster analysis were performed to investigate the relationships of the studied Cyanus taxa.

Microbiome/host interactions describe characteristics that affect the host's health. Shotgun metagenomics includes sequencing a random subset of the microbiome to analyze its taxonomic and metabolic potential. Reconstruction of DNA fragments into genomes from metagenomes (called metagenome-assembled genomes) assigns unknown fragments to taxa/function and facilitates discovery of novel organisms. Genome reconstruction incorporates sequence assembly and sorting of assembled sequences into bins, characteristic of a genome.

In this study, the ground layer species growing in altitudinal zones from sea level to high mountains were investigated according to their distribution, floristic composition and some habitat characteristics in the province of Trabzon in the north-eastern Black Sea region. Surveyed over four growing seasons (1994-1997), 285 taxa from 44 families were recorded in the De¤irmendere and Solakli Çayi river basins in Trabzon.

The possible chromosome rearrangements during evolution of the genus are discussed. It is suggested that the ancestral section of the genus Echinops is Oligolepis, and the most modern one Echinops. The results allowed for the verification of the taxonomic position of some Echinops species, which previously were classified based only on morphological characteristics.
