    Taxonomy of Poa jubata and a new section of the genus (Poaceae)

    TURKISH JOURNAL OF BOTANY.

    Poa jubata A. Kern. is an ephemeral, southeastern European species of which little is known. A molecular phylogenetic analysis of Poa L. including all previously identified major lineages, shows this species to be isolated, with a genotype here designated as J (plastid) J (nrDNA). It is assigned to the monotypic P. sect. Jubatae sect. nov. The section is differentiated from other Poa sections in having 5-nerved upper glumes, very narrow palea flanges, an annual habit, and erect solitary culms. Poa jubata occurs along coastal regions of the Balkans and is rather rare. Two new collections were made in 2015 in Thrace, Turkey, in vernal pool habitats with clay soils, thus expanding its known habitat. The species is described in detail, illustrated, and its relationships are discussed.

    Speciation and genetic diversity in Centaurea subsect. Phalolepis in Anatolia

    Scientific Reports 6 37818.

    Mountains of Anatolia are one of the main Mediterranean biodiversity hotspots and their richness in endemic species amounts for 30% of the flora. Two main factors may account for this high diversity: the complex orography and its role as refugia during past glaciations. We have investigated seven narrow endemics of Centaurea subsection Phalolepis from Anatolia by means of microsatellites and ecological niche modelling (ENM), in order to analyse genetic polymorphisms and getting insights into their speciation. Despite being narrow endemics, all the studied species show moderate to high SSR genetic diversity. Populations are genetically isolated, but exchange of genes probably occurred at glacial maxima (likely through the Anatolian mountain arches as suggested by the ENM). The lack of correlation between genetic clusters and (morpho) species is interpreted as a result of allopatric diversification on the basis of a shared gene pool. As suggested in a former study in Greece, post-glacial isolation in mountains would be the main driver of diversification in these plants; mountains of Anatolia would have acted as plant refugia, allowing the maintenance of high genetic diversity. Ancient gene flow between taxa that became sympatric during glaciations may also have contributed to the high levels of genetic diversity.

    Integrating morphology, phylogeography, and ecological niche modeling to explore population differentiation in North African Common Chaffinches

    Journal of Ornithology 1-13.

    Diagnosing distinct evolutionary taxa requires careful assessment of genetic, morphological, ecological, and behavioral variation within and among populations. In this study, data on phenotype (mensural and plumage coloration), genotype (mitochondrial DNA control-region sequences), and distributional projections derived from ecological niche models, were used to investigate population differentiation of North African Common Chaffinches. Results showed substantial genetic variation among populations, mostly (~56 %) distributed between Libyan populations and other North African populations, rather than within populations. Isolation-by-distance analysis indicated severely restricted gene flow between populations. Historical demographic analyses indicate that population expansion began before the Last Glacial Maximum, which is consistent with ecological niche model paleoprojections; interestingly, differentiation of the Libyan population (Fringilla coelebs harterti) apparently did not take place under the last glacial conditions. Hence, although its taxonomic status must await robust testing using multilocus DNA data, this population is an important element in the conservation of bird diversity in North Africa.

    Rose-ringed Parakeet Populations and Numbers in Europe: A Complete Overview

    The Open Ornithology Journal 9(1) 1-13.

    Purpose: Alien species are considered one of the major causes contributing to the current loss of biodiversity. Over the past few decades, a large and increasing number of alien species have become invasive in many parts of the world. Their impacts range from competition for resources with native species to damage of urban infrastructure. In Europe, over a thousand alien species are now established, of which 74 are birds. Among 12 established alien parrot species in Europe, Introduction: The Rose-ringed Parakeet (RRP) Psittacula krameri (Scopoli, 1769) is the most abundant and widespread. Since the 1960's, RRPs have established more than 100 wild populations in several European countries. For Western Europe, long-term demographic data indicate the species has grown considerably in number, although some populations have failed to persist. Data: Is scarce and dispersed for countries in Central, Eastern and Northern Europe. Therefore, here we present detailed demographic data of RRP for 90 populations in 10 European countries. Furthermore, we present information on the status of the species in another 27 European countries, for which previously no data were published. Conclusion: Our synthesis reveals a positive demographic trend across the continent, although locally, some populations appear to have reached carrying capacity.

    Genome fingerprinting confirms the species status of the Loosestrifes Lysimachia punctata and L. verticillata (Primulaceae)

    Plant Ecology and Evolution 149(3) 335-338.

    Background and aims – Despite their vicariant distribution and slightly distinct morphologies, the Dotted Loosestrife (L. punctata L.) and the Whorled Loosestrife (L. verticillata (Green) Hand.-Mazz.) have sometimes been treated as synonyms, or even confounded by several authors. Here we examine the genetic divergence of these two taxa in order to clarify their species status. Methods – We apply AFLP genome fingerprinting to samples from eleven wild and two naturalized populations, and compile occurrence data from herbaria and public data depositories. Key results – The distribution of genotypes in a multivariate space confirms the distinct species status of the two species, and highlights the absence of natural hybrids between the two in their native area. This result contrasts with the hybrid nature of naturalized populations from northern Europe, likely produced through horticultural practices.

    First records of the warm water shipworm Teredo bartschi Clapp, 1923 (Bivalvia, Teredinidae) in Mersin, southern Turkey and in Olhão, Portugal

    Bioinvasion Records 3(1) 25-28.

    Bivalves of the family Teredinidae are among the most destructive wood-boring species in the sea. We report the first occurrences of the warm-water shipworm Teredo bartschi in Mersin, Turkey, and Olhão, Portugal. The colonisation of the site in Mersin is likely to have occurred by rafting adults originating from the Red Sea, which passed through the Suez Canal (lessepsian migrants). T. bartschi might have been introduced in Olhão Harbour, Portugal, either by rafting adults with larvae transported by currents or by larvae transported by ships in ballast water. These seem to be the first published records of established T. bartschi populations in the Mediterranean and in northeast Atlantic.

    Assessment of genetic structure, habitat suitability and effectiveness of reserves for future conservation planning of the Euphrates soft-shelled turtle Rafetus euphraticus (Daudin, 1802)

    Aquatic Conservation: Marine and Freshwater Ecosystems Forthcoming.

    1. The endangered Euphrates soft-shelled turtle, Rafetus euphraticus, is endemic to the Mesopotamian River Basin in the Middle East. Within recent decades, populations of this aquatic species have been heavily depleted and severely fragmented owing to habitat alteration and destruction by drainage and hydroelectricity dam constructions. Continuing habitat loss and fragmentation are considered the main drivers for the population decline of R. euphraticus. 2. Intraspecific genetic variability was investigated using two mitochondrial gene fragments for 31 specimens covering most of the distributional range of the species. Habitat suitability models were computed using a combination of bioclimatic and remote sensing variables as environmental predictors to assess habitat suitability, habitat fragmentation and coverage by designated protected areas across the range of R. euphraticus. 3. Beyond single substitutions in two sequences, no significant genetic variation could be detected in R. euphraticus. Models show habitat suitability to be high throughout the range of the species, although only a fraction is currently covered by reserves. Habitat suitability and coverage of reserves is highly variable among countries. South-western Iran appears to be ofmajor importance for future conservation strategies. Suitabilitymodels are in concordance with the habitat selection patterns of R. euphraticus. 4. The existing reserve system is considered insufficient and has to be significantly improved in order to sustain viable populations of R. euphraticus. To counter continuing fragmentation and alteration by dam construction, future conservation measures should focus on highlighted priority areas.

    Climate-driven range shifts and demographic events over the history of Kruper's Nuthatch Sitta krueperi

    Bird Study 1-15.

    Capsule This study is the first ever documented evidence of an interglacial refugium during the Last Interglacial for birds in Anatolia and suggests the need of a re-examination of the effects of the Last Interglacial on the geographic distribution and genetic structure of species.Aims We tested whether, in accordance with the ‘refugia within refugia’ model, multiple refugia existed for Kruper's Nuthatch Sitta krueperi during the Last Glacial Maximum or the species survived along the coastal belt of Anatolia through the Late Quaternary glacial–interglacial cycles.Methods An ecological niche model was developed to predict the geographic distribution of Kruper's Nuthatch under reconstructed past (the Last Interglacial and the Last Glacial Maximum), present, and projected future bioclimatic conditions. Also, robust coalescent-based analyses were used to assess demographic events over the history of Kruper's Nuthatch.Results Kruper's Nuthatch survived the Last Glacial Maximum almost along the coastal belt of ...

    The effects of the Late Quaternary glacial-interglacial cycles on Anatolian ground squirrels: range expansion during the glacial periods?

    Biological Journal of the Linnean Society 109(1) 19-32.

    The present study aimed to understand how Anatolian ground squirrels, Spermophilus xanthoprymnus (Bennett, 1835), have responded to global climate changes through the Late Quaternary glacial–interglacial cycles. Accord- ingly, ecological niche modelling was used, together with molecular phylogeography. Using species occurrence data compiled from field observations and relevant sources and the maximum entropy machine learning algorithm in MAXENT, an ecological niche model was developed to predict the potential geographical distribution of S. xanthoprymnus under reconstructed past (the Last Interglacial, approximately 130 000–116 000 years ago and the Last Glacial Maximum, 21 000 years ago) and present (1950–2000) bioclimatic conditions. In addition, using cytochrome b mitochondrial DNA sequences deposited in GenBank and the Bayesian skyline plot in BEAST, demographic events (population fluctuations) were further assessed over the history of Anatolian ground squirrels. Combined ecological niche modelling and molecular phylogeography revealed that S. xanthoprymnus, itself also a temperate (mid-latitude) species, has responded to global climate changes through the Late Quaternary glacial– interglacial cycles in a fashion converse to that of most temperate (mid-latitude) species: its range expanded rather than contracted during the glacial periods and contracted rather than expanded during the interglacial periods. In other words, Anatolian ground squirrels have been in refugia during the interglacial periods, suggesting that the classical paradigm of glacial range contraction and interglacial range expansion for temperate species may not be as general as previously assumed.
