New Insight Into the Phylogeographic Pattern Of
New insight into the phylogeographic pattern of Liriodendron chinense (Magnoliaceae) revealed by chloroplast DNA: east–west lineage split and genetic mixture within western subtropical China Aihong Yang, Yongda Zhong, Shujuan Liu, Lipan Liu, Tengyun Liu, Yanqiang Li and Faxin Yu The Key Laboratory of Horticultural Plant Genetic and Improvement of Jiangxi, Institute of Biological Resources, Jiangxi Academy of Sciences, Nanchang, Jiangxi, China ABSTRACT Background: Subtropical China is a global center of biodiversity and one of the most important refugia worldwide. Mountains play an important role in conserving the genetic resources of species. Liriodendron chinense is a Tertiary relict tree largely endemic to subtropical China. In this study, we aimed to achieve a better understanding of the phylogeographical pattern of L. chinense andtoexploretheroleofmountainsintheconservationofL. chinense genetic resources. Methods: Three chloroplast regions (psbJ-petA, rpl32-ndhF, and trnK5’-matK) were sequenced in 40 populations of L. chinense for phylogeographical analyses. Relationships among chloroplast DNA (cpDNA) haplotypes were determined using median-joining networks, and genetic structure was examined by spatial analysis of molecular variance (SAMOVA). The ancestral area of the species was reconstructed using the Bayesian binary Markov Chain Monte Carlo (BBM) method according to its geographic distribution and a maximum parsimony (MP) tree based on Bayesian methods. Results: Obvious phylogeographic structure was found in L. chinense. SAMOVA Submitted 13 September 2018 revealed seven groups matching the major landscape features of the L. chinense Accepted 26 December 2018 Published 1 February 2019 distribution area. The haplotype network showed three clades distributed in the eastern, southwestern, and northwestern regions. Separate northern and southern Corresponding author Faxin Yu, [email protected] refugia were found in the Wu Mountains and Yungui Plateau, with genetic admixture in the Dalou Mountains and Wuling Mountains. -

Panahi Received 2019. 05. 22; accepted for publication 2019. 11. 20 Panahi, M., 2019. 12. 30: Biogeographic reconstruction of the genus Ferula inferred from analyses of nrDNA and cpDNA sequences. -Iran. J. Bot. 25 (2): 79-94. Tehran. The divergence time of the largely Asian element, the genus Ferula L. (subtribe Ferulinae, tribe Scandiceae, Apiaceae) was initially analyzed using nrDNA, internal transcribed spacer (ITS) sequence data followed with three regions of cpDNA (rps16 and rpoC1 introns and rpoB-trnC intergenic spacers) from 141 representatives of subtribe Ferulinae (Ferula, Dorema, Leutea) and relatives. Further analyses of the biogeographical history of the Ferula group were carried out using BEAST, S-DIVA and BBM in RASP on all datasets. The results suggested that the initial split within Ferulinae occurred during Early Pliocene about 4.8 Ma and earlier ancestor of Ferula group has been originated mostly in Armeno-Iranian province. One descendent giving rises to the Ferula clade and another descendent subsequently underwent further divergence to account for Leutea lineages about 1.8-2 Ma. The rapid diversification within Ferulinae clade has occurred since the Middle Pliocene. Subsequent diversification of the Ferula clade intensified in the Irano-Turanian region during the late Pliocene in the Central Asian zone and toward west in Mediterranean zone during early Pleistocene. The ancestor of Chinese group of Ferula spread from Central Asia to eastern Asia in the Pliocene (2.2-4 Ma). -

Polish Botanical Journal 60(2): 147–161, 2015 DOI: 10.1515/pbj-2015-0024 PHYTOGEOGRAPHICAL ANALYSIS OF EUPHORBIA SUBGENUS ESULA (EUPHORBIACEAE) Dmitry V. Geltman Abstract. Euphorbia subg. Esula is one of four major clades within the genus. A geographical analysis of the 466 species in the subgenus is reported here. Every species was assigned to one of 29 geographical elements clustered in ten groups of ele- ments. This geographical analysis showed that the Tethyan group (comprising nine geographical elements) clearly dominates the subgenus and contains 260 species (55.79% of the total number of species). The most numerous geographical elements are Irano-Turanian (105 species) and Mediterranean (85). Other significant groups of elements are Boreal (91 species, 19.54%), East Asian (40 species, 8.58%), Madrean (26 species, 5.58%), Paleotropical (23 species, 4.94%) and South African (16 species, 3.43%). The area of the Tethyan floristic subkingdom is the center of the modern diversity of E. subg. Esula. It is likely that such diversity is the result of intensive speciation that took place during the Eocene–Miocene. Key words: Euphorbia subg.

Chapter 3 MATERIAL and METHODS
Chapter 3 MATERIAL AND METHODS 3.1. Introduction The study of flora consists of plant and situation of plant habitat. There are many definitions for word "flora". The word "flora" refers to the plants occurring within a given region. A Flora may contain anything from a simple list of the plants occurring in an area to a very detailed account of those plants. Floras are different from popular manuals in that they attempt to cover all of the plants, rather than only the most common or conspicuous ones. When a researcher wants to study Flora he/or she can understand many things from that. A Flora ahnost always contains scientific names, and it may also include common names, literature references, descriptions, habitats, geographical distribution, illustrations, flowering times, and notes. Less often, Floras includes such specialized information as data on plant chemistry, reproduction, chromosome numbers, and population occurrences. Sometimes, the plants are listed alphabetically, and sometimes they are represented within a classification system that indicates which plants are most similar or are thought to be related. Floras often also include devices called "keys" that enable the user to identify an unknown plant. Floristic elements are most often defined subjectively by grouping plant ranges into types based on descriptions provided by floras and manuals (McLaughlin and Bowers, 1990). By study of floristic traits of an area, it is possible to describe floristic province and phytogeographical regions. The delimitation of floristic provinces and sub-provinces is mainly based on the distribution boundaries of vascular plant species (Yurtsev, 1994) which is known as true plants. -
Ecosystems and Diversity of the Sierra Madre Occidental
Ecosystems and Diversity of the Sierra Madre Occidental M. S. González-Elizondo, M. González-Elizondo, L. Ruacho González, I.L. Lopez Enriquez, F.I. Retana Rentería, and J.A. Tena Flores CIIDIR I.P.N. Unidad Durango, Mexico Abstract—The Sierra Madre Occidental (SMO) is the largest continuous ignimbrite plate on Earth. Despite its high biological and cultural diversity and enormous environmental and economical importance, it is yet not well known. We describe the vegetation and present a preliminary regionalization based on physio- graphic, climatic, and floristic criteria. A confluence of three main ecoregions in the area corresponds with three ecosystems: Temperate Sierras (Madrean), Semi-Arid Highlands (Madrean Xerophylous) and Tropical Dry Forests (Tropical). The Madrean region harbors five major vegetation types: pine forests, mixed conifer forests, pine-oak forests, oak forests and temperate mesophytic forests. The Madrean Xerophylous region has oak or pine-oak woodlands and evergreen juniper scrub with transitions toward the grassland and xerophylous scrub areas of the Mexican high plateau. The Tropical ecosystem, not discussed here, includes tropical deciduous forests and subtropical scrub. Besides fragmentation and deforestation resulting from anthropogenic activities, other dramatic changes are occurring in the SMO, including damage caused by bark beetles (Dendroctonus) in extensive areas, particularly in drought-stressed forests, as well as the expansion of chaparral and Dodoneaea scrub at the expense of temperate forest and woodlands. Comments on how these effects are being addressed are made. Introduction as megacenters of plant diversity: northern Sierra Madre Occidental and the Madrean Archipelago (Felger and others 1997) and the Upper The Sierra Madre Occidental (SMO) or Western Sierra Madre is the Mezquital River region (González-Elizondo 1997). -

Luciogobius elongatus is distinguished from congeners by very elongated and naked body, 42-44 vertebrae, 6-7 dorsal soft rays, and no free rays on pectoral fin, and L. platycephalus is characterized by having very depressed head, naked body, 40-41 vertebrae, 10-11 dorsal soft rays, and pectoral fin with only upper 2-4 free rays. We propose the new Korean name “Ga-neun-mi-kkeun-mang-dug”, “Nab-jak-mi-kkeun- mang-dug” for L. elongatus and L. platycephalus, respectively.
