Ebook "Applied ecology and human dimensions in biological conservation" provides both the conceptual basis and technological tools that are necessary to identify and solve problems related to biodiversity governance. The authors discuss intriguing evolutionary questions, which involve the sometimes surprising adaptive capacity of certain organisms to dwell in altered and/or changing environments that apparently lost most of their structure and functionality.

Inocybe viscida sp. nov., a novel species found in a forest with old trees of Pinus brutia and tertiary relict endemic Liquidambar orientalis in coastal area of southwestern Turkey, is described and illustrated. We present this new species based on morphological and molecular data from nuclear rDNA internal transcribed spacer region (ITS1-5.8SITS2 = ITS) and the portions of nuc 28S rRNA (LSU) gene. Comprehensive description, field photographs, line drawings of the microscopic features and comparisons with phenetically similar taxa and phylogenetically related species are discussed.

Achillea alimeana Semiz & Uysal sp. nov. of sect. Santolinoidea DC. (Asteraceae), was described, diagnosed and illustrated as a new species. It was collected from Akdağ Mountains in Denizli Province. In this paper, the diagnostic characters of A. alimeana and its similar species were discussed in the morphological, palynological and molecular findings. As regards the new species, some notes on the ecology, conservation status, and distribution were submitted. A diagnostic key was given for related taxa.

Saxifraga artvinensis V.A.Matthews, which is endemic to Turkey, was discovered on Tiryal Mountain (A8 Artvin, northeastern Turkey). Approximately 175 km from its type locality, a new population of the species was discovered, in the Picea orientalis forest in the Altındere Valley National Park, in A7 Trabzon (northeastern Turkey). A comparison with the known population of S. artvinensis confirmed that this new population represented a new taxon and is described as S. artvinensis subsp. meryemii Terzioğlu & Coşkunç.

This study aimed to characterize the stem, peduncle, and leaf anatomy of 22 species of Sedum senso lato distributed in Iran. The results showed that the presence of tanniniferous storage cells in stems and leaves, distinct xylem vessels in stems, and the shape of peduncle cross sections, were taxonomically informative evidence, and isolated Phedimus from the other studied taxa of Sedum s.l., whereas hairy leaves and peduncles containing starch storage cells were identified as Prometheum and Hylotelephium respectively.

Nutlets of 13 taxa of subfamily Cyperoideae (Cyperaceae) from Egypt were investigated using light and scanning electron microscopes to ascertain the taxonomic utility of the nutlet in corroborating and elaborating on distinctions between closely related genera and species. The studied taxa included representatives of tribes Fuireneae, Cypereae, Cariceae, Abildgaardieae and Schoeneae. Nutlet shape, size, color, surface, epidermal cell shape, anticlinal boundaries, outer periclinal cell wall and relief of outer cell walls were provided.

The question of whether bacterial species objectively exist has long divided microbiologists. A major source of contention stems from the fact that bacteria regularly engage in horizontal gene transfer (HGT), making it difficult to ascertain relatedness and draw boundaries between taxa. A natural way to define taxa is based on exclusivity of relatedness, which applies when members of a taxon are more closely related to each other than they are to any outsider. It is largely unknown whether exclusive bacterial taxa exist when averaging over the genome or are rare due to rampant hybridization.

Trypanosoma conorhini and Trypanosoma rangeli, like Trypanosoma cruzi, are kinetoplastid protist parasites of mammals displaying divergent hosts, geographic ranges and lifestyles. Largely nonpathogenic T. rangeli and T. conorhini represent clades that are phylogenetically closely related to the T. cruzi and T. cruzi-like taxa and provide insights into the evolution of pathogenicity in those parasites. T. rangeli, like T. cruzi is endemic in many Latin American countries, whereas T. conorhini is tropicopolitan. T. rangeli and T. conorhini are exclusively extracellular, while T.

Assembling genes from next-generation sequencing data is not only time consuming but computationally difficult, particularly for taxa without a closely related reference genome. Assembling even a draft genome using de novo approaches can take days, even on a powerful computer, and these assemblies typically require data from a variety of genomic libraries.

Modern plant taxonomy reflects phylogenetic relationships among taxa based on proposed morphological and genetic similarities. However, taxonomical relation is not necessarily reflected by close overall resemblance, but rather by commonality of very specific morphological characters or similarity on the molecular level.

Distinct expression domains of WUSCHEL-RELATED HOMEOBOX (WOX) gene family members are involved in patterning and morphogenesis of the early embryo in Arabidopsis. However, the role of WOX genes in other taxa, including gymnosperms, remains elusive.

A plant’s microbiota has various implications for the plant’s health and performance; however, the roles of many microbial lineages, particularly Archaea, have not been explored in detail. In the present study, analysis of archaea-specific 16S rRNA gene fragments and shotgun-sequenced metagenomes was combined with visualization techniques to obtain the first insights into the archaeome of a common salad plant, arugula (Eruca sativa Mill.).

This paper introduced the testing results of three methods (analysis of morphological characteristics using numerical phenetics, the whole-cell proteins using SDS-PAGE and the DNA barcode sequences) used for determination of the genetic diversity of some earthworm species belonging to the Pheretima species group in the Mekong Delta (Amynthas paraalexandri, A. juliani, Metaphire posthuma, M. bahli, M. peguana, M. houlleti, Metaphire sp.8, Polypheretima elongata and P. taprobanae).

The genus Malcolmia W.T.Aiton is taxonomically problematic, and some of its species have recently beentransferred to the genera Strigosella Boiss. and Zuvanda Dvorák. Three species of this genus are native to Turkey. The revision studies based on molecular data, which were collected in the past few years, display the phylogenetic relations and the systematic positions of the taxa more reliably and apparently.

The soils of the plant taxa were medium textured, sand or sandy-loam, saltless or a little salty, neutral, limy, rich in potassium and with very little phosphorous, and with medium levels of nitrogen and organic matter. G. antari, which had the greatest lime content, had the lowest number of leaves. G. muralis and G. tubulosa had the lowest saturation values and lime content but the greatest number of leaves.
