Abstract This work calculates and analyses monthly, seasonal and annual precipitation trends over continental Spain between 1961 and 2010, according to data from 144 weather stations widely distributed throughout the study area. The magnitude and sign of the trends were evaluated with Sen’s slope estimator and their statistical significances were determined with the non-parametric Mann-Kendall test. In general terms, the rainfall trends for the period and the study area are mainly non non-significant at the monthly, seasonal and annual timescales. By and large, we noted the highest number of weather stations with positive significant trends in September and October, whereas the highest number of stations with negative significant trends was observed in February, June, winter, summer and at the annual time- scale. The most pronounced decreases occurred in June (–18.58 mm/50years) and in summer (-27.67 mm/50years) in the south, which points to an intensification of mediterraneity in this area. We observed a sign asymmetry in significant rainfall trends during winter, spring and at the annual timescales between the north (negative) and the southeast (positive).

En la Región del Biobío, la Estación de Biología Terrestre de Hualpén (EBT) conserva un remanente de este tipo de bosque, para el cual no existen revisiones que describan su flora, lo que dificulta la formulación y el desarrollo de estrategias para su protección y conservación. Este trabajo tiene como objetivos: a) describir la composición taxonómica de las plantas vasculares de la ETB y b) entregar información sobre su origen geográfico, hábito y estado de conservación. El listado florístico obtenido incluye tanto las especies determinadas a través del muestreo sistemático en el área de estudio durante un año, así como las especies de la EBT ingresadas en la colección del Herbario de la Universidad de Concepción. Se determinaron 294 especies de plantas vasculares de las cuales 71 son endémicas, 124 son nativas y 99 son introducidas.

Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.

J.F. Macbr. (Asparagaceae), una geófita endémica de Chile. Se realizaron cinco tratamientos de polinización controlada (agamospermia, autogamia autónoma, autopolinización, polinización cruzada y natural / control). Ninguna de las flores emasculadas y sin polinizar produjo frutos, lo que indica que esta especie no es apomíctica y, por lo tanto, necesita polen para la producción de semillas. La fructificación en el tratamiento de polinización cruzada (70,0%) fue alta y similar al porcentaje alcanzado a través de la polinización natural (90,9%). A pesar del porcentaje menor en la prueba de autopolinización (43,3%), la autogamia autónoma (90,0%) se acercó a los altos valores alcanzados en los dos primeros tratamientos mencionados. Para el promedio de semillas por flor tratada, los resultados concuerdan con los de fructificación.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

  • LEAFLETS of WESTERN BOTANY
    MT^ LEAFLETS of WESTERN BOTANY INDEX Volumes I to X 1932 TO 1966 LEAFLETS OF WESTERN BOTANY INDEX Volumes I to X 1932 TO 1966 Compiled by JOHN THOMAS HOWELL and ANITA M. NOLDEKE SAN FRANCISCO, CALIFORNIA 1968 Published by John Thomas Howell Printed by Gillick Printing, Inc. Berkeley, California FOREWORD This cumulative index to Leaflets of Western Botany is based almost entirely on the published indexes of each of the ten volumes, those of volumes 1 to 7 having been compiled by me, and of volumes 8 to 10 by Anita Noldeke. Unfortunately, in the interest of economy, the earliest indexes are not as com- plete as I might wish, although such deficiencies as have been noted have been made up in the present work. Also included here are all plant names in various lists that were not indexed originally, such as those in Alice Eastwood's catalogue of plants on the Channel Islands (vol. 3, pages 55 to 76) and Jean M. Lindsdale's list of plants on the Hastings Reservation (vol. 7, pages 201 to 218). Besides the correction of certain errors in the volume indexes, we have made further corrections of original text spellings in this cumulative index, corrections that would have appeared in volume errata had they been detected in time. Such corrections in the present index are usually followed by the original misspelling in quotation marks. All names, whether accepted or synonymous, are given in regular (Roman) type, except for new names which are given in heavy (bold face) type. Of these new names, there are more than 1000 in this index.

  • "Freeze Survival Survey of 21 Palm Species in New Orleans and Vicinity"
    Freeze Survival Survey of 21 Palm Species in New Orleans and Vicinity Severn C. Doughty1, Daniel J. Gill2, and David C. Blouin3 Additional index words. cold damage, geographic populations, landscape survival, palms Summary. Landscape palms were sur- veyed for cold damage 8 to 10 months after the coldest weather episode re- corded this century in the New Orleans, La., area. Fourteen genera and 21 species of palms totaling 9039 individuals were surveyed and assign- ed to one of three condition catego- ries within six geographic areas. Area 1, north of Lake Pontchartrain, was not a reliable area for the majority of the 21 species found. South of Lake Pontchartrain, areas 2-6 were consid- ered statistically better for overall palm survival, with area 3 best follow- ed by areas 4, 2, 5, and 6. Although species survival depended somewhat on area, 10 species were found to be statistically reliable south of Lake Pontchartrain: Brahea armata, Cha- maedorea microspadix, Phoenix can- ariensis, Rhapidophyllum hystrix, Sabal mexicana, S. minor, S. palmetto, Sabal spp., Sabal spp. seedlings, and Trachy- carpus fortune;. Two species, Phoenix reclinata and Phoenix spp., were found to be marginal and seven spe- cies were found to be unreliable: Butia capitata, Chamaerops humilis, Livistona chinensis, Rhapis excelsa, Syagrus romanzoffiana, Washingtonia filifera, and W. robusta. Due to low individual numbers, survival for three species could not be reliably esti- mated: Arenga engleri, Phoenix dactyf- ifera, and Serenoa repens. alms are monocotyledonous plants in the order Arecales, P which are recognized as a natu- ral and isolated family, the Palmae or Arecaceae (Tomlinson, 1990; Uhl and Dransfield, 1987).
