  • Molecular Evolutionary Rates Predict Both Extinction and Speciation In
    Lancaster BMC Evolutionary Biology 2010, 10:162 http://www.biomedcentral.com/1471-2148/10/162 RESEARCH ARTICLE Open Access MolecularResearch article evolutionary rates predict both extinction and speciation in temperate angiosperm lineages Lesley T Lancaster Abstract Background: A positive relationship between diversification (i.e., speciation) and nucleotide substitution rates is commonly reported for angiosperm clades. However, the underlying cause of this relationship is often unknown because multiple intrinsic and extrinsic factors can affect the relationship, and these have confounded previous attempts infer causation. Determining which factor drives this oft-reported correlation can lend insight into the macroevolutionary process. Results: Using a new database of 13 time-calibrated angiosperm phylogenies based on internal transcribed spacer (ITS) sequences, and controlling for extrinsic variables of life history and habitat, I evaluated several potential intrinsic causes of this correlation. Speciation rates (λ) and relative extinction rates (ε) were positively correlated with mean substitution rates, but were uncorrelated with substitution rate heterogeneity. It is unlikely that the positive diversification-substitution correlation is due to accelerated molecular evolution during speciation (e.g., via enhanced selection or drift), because punctuated increases in ITS rate (i.e., greater mean and variation in ITS rate for rapidly speciating clades) were not observed. Instead, fast molecular evolution likely increases speciation rate (via increased mutational variation as a substrate for selection and reproductive isolation) but also increases extinction (via mutational genetic load). Conclusions: In general, these results predict that clades with higher background substitution rates may undergo successful diversification under new conditions while clades with lower substitution rates may experience decreased extinction during environmental stasis.

Caldasia 43(1):49–64. doi: https://dx.doi.org/10.15446/caldasia.v43n1.84230. • Online Publishing: 9/Nov/2020 ABSTRACT This article describes the diversity and use of trees and shrubs in smallholder farming systems in three municipalities of the department of Boyacá in the Colombian Andes, and tests the relations between spe- cies richness, use, and a set of socio-economic and structural variables. We conducted ethnobotanical walks and semi-structured interviews on 24 farms to characterize all tree and shrub species. In total, we recorded 142 species with a predominance of natives (88) versus exotics (54). Species richness ranged between four and 40 (X = 25.17; SD = 10.13) per farm and was homogeneous among the municipalities (P > 0.05, Kruskal-Wallis test). We recorded 52 wild species, eight of them endemic, all representative of the surrounding native flora, of which 23 % had some type of use. Cultivated species were mostly represented by exotics that had been planted primarily as live fences, ornamentals, or edibles.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

ON THE BASIS OF MORPHOLOGY OF SELECTIVE ATTRIBUTES: EPICALYX, STAMINAL TUBE, STIGMATIC HEAD AND TRICHOME *Saikat Naskar and Rabindranath Mandal Department of Botany, Barasat Govt. College, Barasat, Kolkata- 700124, West Bengal, India *Author for Correspondence: [email protected] ABSTRACT Epicalyx, staminal tube, stigma and trichome morphological characters have been used to characterize some common members of Malvaceae s.s. These characters have been analyzed following a recent molecular phylogenetic classification of Malvaceae s.s. Stigmatic character is effective for segregation of the tribe Gossypieae from other tribes. But precise distinction of other two studied tribes, viz. Hibisceae and Malveae on the basis of this character proved to be insufficient. Absence of epicalyx in Malachra has indicated an independent evolutionary event within Hibisceae. Distinct H-shaped trichome of Malvastrum has pointed out its isolated position within Malveae. Staminal tube morphological similarities of Abutilon and Sida have suggested their closeness. A key to the genera has been provided for identification purpose. Keywords: Malvaceae s.s., Epicalyx, Staminal Tube, Stigma, Trichome INTRODUCTION Epicalyx and monadelphous stamens are considered as key characters of the family Malvaceae s.s. Epicalyx was recognized as an important character for taxonomic value by several authors (Fryxell, 1988; Esteves, 2000) since its presence or absence was employed to determine phylogenetic interpretation within the tribes of Malvaceae s.s.

  • Checklist of the Vascular Alien Flora of Catalonia (Northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3
    BOTANICAL CHECKLISTS Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.63608 Checklist of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3 Received: 7 March 2019 / Accepted: 28 June 2019 / Published online: 7 November 2019 Abstract. This is an inventory of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) updated to 2018, representing 1068 alien taxa in total. 554 (52.0%) out of them are casual and 514 (48.0%) are established. 87 taxa (8.1% of the total number and 16.8 % of those established) show an invasive behaviour. The geographic zone with more alien plants is the most anthropogenic maritime area. However, the differences among regions decrease when the degree of naturalization of taxa increases and the number of invaders is very similar in all sectors. Only 26.2% of the taxa are more or less abundant, while the rest are rare or they have vanished. The alien flora is represented by 115 families, 87 out of them include naturalised species. The most diverse genera are Opuntia (20 taxa), Amaranthus (18 taxa) and Solanum (15 taxa). Most of the alien plants have been introduced since the beginning of the twentieth century (70.7%), with a strong increase since 1970 (50.3% of the total number). Almost two thirds of alien taxa have their origin in Euro-Mediterranean area and America, while 24.6% come from other geographical areas. The taxa originated in cultivation represent 9.5%, whereas spontaneous hybrids only 1.2%. From the temporal point of view, the rate of Euro-Mediterranean taxa shows a progressive reduction parallel to an increase of those of other origins, which have reached 73.2% of introductions during the last 50 years.
