  • 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.

Rajapaksha1, C. de Alwis1 1Butterfly Conservation Society of Sri Lanka, 762/A, Yatihena, Malwana, Sri Lanka 2 E-mail: [email protected] Abstract Larval food plants (LFPs) of Sri Lankan butterflies are poorly documented in the historical literature and there is a great need to identify LFPs in conservation perspectives. Therefore, the current study was designed and carried out during the past decade. A list of LFPs for 207 butterfly species (Super family Papilionoidea) of Sri Lanka is presented based on local studies and includes 785 plant-butterfly combinations and 480 plant species. Many of these combinations are reported for the first time in Sri Lanka. The impact of introducing new plants on the dynamics of abundance and distribution of butterflies, the possibility of butterflies being pests on crops, and observations of LFPs of rare butterfly species, are discussed. This information is crucial for the conservation management of the butterfly fauna in Sri Lanka. Key words: conservation, crops, larval food plants (LFPs), pests, plant-butterfly combination. Introduction Butterflies go through complete metamorphosis 1949). As all herbivorous insects show some and have two stages of food consumtion.

  • 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.

  • Native/Exotic/Invasive
    Invasive Species Caesar weed • Scientific name: Urena lobata • Order name: Malvales • Family Name: Malvaceae • Native/Exotic/Invasive: Invasive • History: Caesar weed was first introduced to the United States because of its textile properties which was believed to be a cheaper and easier replacement of cotton; it was concluded that the plant was not as efficient compared to cotton because of the seed's long dormancy and impermeable seed coat (7). Caesar Weed is known for its rapid growth rate in disturbed areas which are becoming more common as human population increases and natural areas are being developed (7). Sword fern • Scientific Name: Polystichum munitum • Order name: Polypodiales • Family name: Dryopteridaceae • Native/Invasive/Exotic: Invasive • History: Sword fern is also known as “king of the northwest ferns” or “Christmas fern” and is an invasive species in Florida. Swords ferns were used medicinally to cure diarrhea or by rubbing the fronds on nettle stings to reduce the pain. This species has a wide tolerance to soil and moisture which makes it perfect for the Florida environment which ranges from sunny to flooding in a span of a few months (4). Air potato • Scientific name: Dioscorea bulbifera • Order name: Dioscoreales • Family name: Dioscoreaceae • native/exotic/invasive: Invasive • History: This species is an invasive which has caused a major disturbance to the vegetative community in Moccasin Lake Park; they are also NOT EDIBLE. Air potato can grow up to eight inches a day and grows potato like tubers which produces more air potato plants. This plant can quickly overtake an area, pushing out native species; some ways to get rid of it are to cut it down, burn it, or freeze the bulbs (sterilization).

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems.

    IAWA Journal, Vol. 27 (2), 2006: 129–136 WOOD ANATOMY OF CRAIGIA (MALVALES) FROM SOUTHEASTERN YUNNAN, CHINA Steven R. Manchester1, Zhiduan Chen2 and Zhekun Zhou3 SUMMARY Wood anatomy of Craigia W.W. Sm. & W.E. Evans (Malvaceae s.l.), a tree endemic to China and Vietnam, is described in order to provide new characters for assessing its affinities relative to other malvalean genera. Craigia has very low-density wood, with abundant diffuse-in-aggre- gate axial parenchyma and tile cells of the Pterospermum type in the multiseriate rays. Although Craigia is distinct from Tilia by the pres- ence of tile cells, they share the feature of helically thickened vessels – supportive of the sister group status suggested for these two genera by other morphological characters and preliminary molecular data. Although Craigia is well represented in the fossil record based on fruits, we were unable to locate fossil woods corresponding in anatomy to that of the extant genus. Key words: Craigia, Tilia, Malvaceae, wood anatomy, tile cells. INTRODUCTION The genus Craigia is endemic to eastern Asia today, with two species in southern China, one of which also extends into northern Vietnam and southeastern Tibet. The genus was initially placed in Sterculiaceae (Smith & Evans 1921; Hsue 1975), then Tiliaceae (Ren 1989; Ying et al. 1993), and more recently in the broadly circumscribed Malvaceae s.l. (including Sterculiaceae, Tiliaceae, and Bombacaceae) (Judd & Manchester 1997; Alverson et al. 1999; Kubitzki & Bayer 2003). Similarities in pollen morphology and staminodes (Judd & Manchester 1997), and chloroplast gene sequence data (Alverson et al. 1999) have suggested a sister relationship to Tilia.

Bhatt1 Department of Pharmacy , S. V. Govt. Polytechnic., Bhopal, India Received January 22, 1980 Family Malvaceae includes many familier plants of cultivation notably cotton . Cytological work on economically important plants of this family has received greater attention, though work has also been done on a few wild species by some workers like Youngman (1927), Davie (1933), Skovsted (1935, 1941), Bates (1967), Bates and Blanchard (1970), Hazra and Sharma (1971), Kachecheba (1972), Bhatt and Dasgupta (1976). However, detailed meiotic study has not been done on many genera and species of the family which is necessary to know the type of ploidy and the basic numbers of chromosomes from which the evolution might have progressed . The present investigation includes 15 species belonging to the tribe Hibisceae and Ureneae of the family Malvaceae. The species of the tribe Ureneae are simple polyploids of seven (Skovsted 1935) which has also been noticed in the present work. However, different chromosome numbers have been reported in the tribe Hibisceae. This vast range of chromosome numbers in the tribe especially necessiated the study of chromosome numbers and the ploidy level. This investigation also aimed at understanding the basic chromosome numbers from which the evolution is supposed to have progressed and the evaluation of systematic position of different taxa as understood at present. Out of 15 species studied meiotic study has been done for the first time in Hibis cus vitifolius, H. hirtus, H.

  • Evaluation of the Long-Term Effects of Urena Lobata Root Extracts on Blood Glucose and Hepatic Function of Normal Rabbits
    Journal of Toxicology and Environmental Health Sciences Vol. 3(8) pp. 204-213, August 2011 Available online at http://www.academicjournals.org/JTEHS ISSN 2006-9820 ©2011 Academic Journals Full Length Research Paper Evaluation of the long-term effects of Urena lobata root extracts on blood glucose and hepatic function of normal rabbits Akhere A. OMONKHUA1* and Iyere O. ONOAGBE2 1Department of Biochemistry, Adekunle Ajasin University, Akungba-Akoko, Ondo State, Nigeria. 2Department of Biochemistry, University of Benin, Benin City, Nigeria. Accepted 30 June, 2011 Urena lobata is one of the medicinal plants used to treat diabetes in Nigeria. Its hypoglycaemic and anti- diabetic activities have been demonstrated. This study was designed to evaluate the long term effects of daily oral administration of aqueous extracts of U. lobata roots in normal rabbits. Parameters such as body weight, blood glucose and liver function tests were monitored at specific intervals in the serum for 24 weeks, and in the tissue. U. lobata significantly (P<0.05) reduced the body weight and fasting blood sugar of treated rabbits. Indicators of cholestasis, alkaline phosphatase and -glutamyl transferase, as well as serum direct bilirubin concentration, were initially significantly (P<0.05) increased, these parameters returned to the levels of control before the 10th week of monitoring and tissue enzymes were not depleted, suggesting that the initial toxic response was not sustained. Markers of hepatocyte injury; alanine transaminase and aspartate transaminase, were initially slightly elevated but subsequently returned to control levels. U. lobata root had no significant effects on serum total proteins, albumin and globulins. Regulation of dose and frequency of consumption of U.
