  • Chromosomes and Phylogeny in Crepis
    'y CHROMOSOMES AND PHYLOGENY IN CREPIS BY LILLIAN HOLLINGSHEAD AND ERNEST B. BABCOCK inn University of California Publications in Agricultural Sciences Volume 6, No. 1, pp. 1-53, 24 figures in text Issued January 4, 1930 University of California Press Berkeley, California Cambridge University Press London, England CHROMOSOMES AND PHYLOGENY IN CREPIS BY LILLIAN HOLLINGSHEAD and EENEST B. BABCOCK INTRODUCTION In connection with genetic and taxonomic studies of Crepis, an examination of as many species as could be brought into cultivation has been in progress for about ten years. The earlier work on the chromosomes was done by Dr. Margaret Mann Lesley, who studied particularly numbers and sizes (Mann, 1922, 1925; Babcock and Lesley, 1926). The work of M. Navashin (1925, 1926) and Taylor (1925, 1926), who described satellites and constrictions for the first time in this genus, showed that a closer morphological study of the chromosomes from suitably fixed material would be of value for com- parative studies of related species. It is the purpose of this paper to present our knowledge of number and morphology of the chromosomes in seventy species and to con- sider this evidence in relation to a system of classification based on phylogenetic relationship. But the present paper is not intended to serve as a taxonomic treatise. Therefore no keys or descriptions of species will appear and there will be no attempt to set forth the detailed evidence for the phylogenetic groupings proposed, as such descriptions and data will appear in a taxonomic treatment now in preparation. The specific names used have been carefully verified as to identity, priority, and authorship, and are in nearly every case the same as those which will be used in later publications.

Bot. Fennici 42: 411–426. Vegetation of an area of 500 km2 in the western Khentey Mountains, northern Mon- golia is phytosociologically classified with the help of 254 relevés. Twenty-one main vegetation units are described. The study area is situated at the interface between the western Siberian dark taiga, the eastern Siberian light taiga and the Mongolian-Daurian forest steppe. A small-scale pattern of these three major vegetation types was found depending on site characteristics. Dark taiga forests of Pinus sibirica, Abies sibirica, Picea obovata, and Larix sibirica grow at the most humid sites. Light taiga forests dominated by Larix sibirica and Betula platyphylla occur on relatively dry northern slopes of the lower montane belt. Sun-exposed, southern slopes of the lower montane belt are covered by montane meadow and mountain steppe. DCA ordination suggests that the distribution of vegetation types depends on water supply and altitude.

Knowledge of present-day communities and ecosystems resembling those reconstructed from the fossil record can help improve our understanding of historical distribution patterns and species composition of past communities. Here, we use a unique data set of 570 plots explored for vascular plant and 315 for land-snail assemblages located along a 650-km-long transect running across a steep climatic gradient in the Russian Altai Mountains and their foothills in southern Siberia. We analysed climatic and habitat requirements of modern populations for eight land-snail and 16 vascular plant species that are considered characteristic of the full-glacial environment of central Europe based on (i) fossil evidence from loess deposits (snails) or (ii) refugial patterns of their modern distribu- tions (plants). The analysis yielded consistent predictions of the full-glacial central European climate derived from both snail and plant populations. We found that the distribution of these 24 species was limited to the areas with mean annual temperature varying from À6.7 to 3.4 °C (median À2.5 °C) and with total annual precipitation vary- ing from 137 to 593 mm (median 283 mm).

(2012): Red List of vascular plants of the Czech Republic: 3rd edition. – Preslia 84: 631–645. The knowledge of the flora of the Czech Republic has substantially improved since the second ver- sion of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979 to 2000 to 2012, there has been an increase in the total number of taxa included in the Red List (from 1190 to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered.

David Fairchild, in company with P. H. Dorsett, made an extended tour along the northern coast of Sumatra and also spent some time in Java and Ceylon. Their itinerary included the Sibolangit Botanic Garden, near Medan, Sumatra, and the Hakgala Botanic Garden, Newara Eliya, Ceylon. The material collected came from these botanic gardens, from the markets of the native villages visited, and from the wild. It consisted for the most part of fruit-bearing plants, ornamentals, and leguminous plants of possible value as cover crops for the warmer parts of the United States. Breeders of small fruits will be interested in the numerous species of Rubus (Nos. 67592 to 67604; 67728 to 67740) obtained mostly in Sumatra. Sev- eral species of Ficus (Nos. 67557 to 67570; 67696 to 67705) from Sumatra will be tested in southern Florida, where already a number of these wild figs have proved popular as shade trees. F. A. McClure continued to work in the general vicinity of Can- ton, China, collecting plant material largely from the native markets of the neighboring villages.

Chornomors’k. bot. z., 14 (3): 204–212. doi: 10.14255/2308-9628/18.143/1 The article deals with wild species of ornamental herbs belonging to the family Asteraceae collected in Quba and Qusar districts of Azerbaijan during 2012–2017. In total, more than 120 specimens were collected and identified based on the main diagnostic morphologic characters. Altogether 49 species belonging to 28 genera and 11 tribes were registered, considering the latest taxonomic and nomenclatural changes. New localities of Cyanus cheiranthifolius and Leontodon danubialis were found in Quba district (the Great Caucasus). The relict species Callicephalus nitens and the Caucasus endemic species Tanacetum leptophyllum were also found in the studied region. The life forms and morphological types, diversity patterns of plants depending on altitude and soil humidity were reflected. Perennial plants, as compared to annuals, are dominant in the districts. Erigeron acris and Lactuca serriola may grow as both annual and/or biennials, while Carduus nutans is mainly biennial. Senecio vernalis may grow as an annual, biennial or perennial plant, depending on its habitats and local conditions. Morphological features, such as root systems, branching patterns, leaf outlines and flowers arrangement, are very variable and depend on the growing environment.

  • Tall Herb Dark Coniferous Forests As Modern Refugia of Biological Diversity of Northern Eurasia (On Example of Pechora-Ilych Nature Reserve)

Izrael Institute of global climate and ecology, Glebovskaya st., 20в, Moscow, 107258, Russia Abstract. Reconstruction of prehistoric forests can be based on restoring the areas of key species of plants and animals in those still preserved in refugiua which include tall herb forests. The main characteristic of unique boreal tall herb spruce-fir forests (association of Aconito septentrionalis- Piceetum obovatae) is presented in comparison with green moss spruce-fir forests (Eu-Piceetum abietis) that dominate in the taiga zone. Using the example of tall herb forests in the Pechora-Ilych Nature Reserve, we identified the following signs of intact forests of the Northern Eurasia: high diversity of vascular plant and moss species; full set of microsites connected with a tree-falls, well-defined gap-mosaic; diversity of ecological-coenotic groups; uneven-aged structure of tree species populations; fertile soil and rich soil biota; presence of broad-leaved forest markers such as ephemeroids (Corydalis solida, Anemone spp., Gagea spp., etc.); presence of broad-leaved tree species in paleo-spectra. The northern dark coniferous forests may also be regarded as historic refugiua because they were less disturbed by humans and probably less exposed to fire.
