Early Eocene climates were globally warm, with ice-free conditions at both poles. Early 16 Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate biota, 17 but also with abundant thermophilic elements such as crocodilians, and mesothermic taxodioid 18 conifers and angiosperms. The globally warm early Eocene was punctuated by geologically brief 19 hyperthermals such as the Paleocene-Eocene Thermal Maximum (PETM), culminating in the 20 Early Eocene Climatic Optimum (EECO), during which the range of thermophilic plants such as 21 palms extended into the Arctic. Climate models have struggled to reproduce early Eocene Arctic 22 warm winters and high precipitation, with models invoking a variety of mechanisms, from 23 atmospheric CO2 levels that are unsupported by proxy evidence, to the role of an enhanced 24 hydrological cycle to reproduce winters that experienced no direct solar energy input yet remained 25 wet and above freezing. -

A total of 281 individuals were used to construct regional descriptions of D. kingianum and 139 individuals were measured for 19 morphological characters, and similarities and differences among specimens summarised using multivariate statistical methods. Patterns of morphological variation within D. kingianum are consistent with a single variable species that expresses clinal variation, with short-growing plants in the south and taller plants in the northern part of the distribution. The nrITS gene tree suggests two subgroups within D. kingianum subsp. kingianum, one comprising northern, the other southern individuals, which may overlap in the vicinity of Dorrigo, New South Wales.

Review of Selected Literature and Epiphyte Classification
--------- -- ---------· 4 CHAPTER 1 REVIEW OF SELECTED LITERATURE AND EPIPHYTE CLASSIFICATION 1.1 Review of Selected, Relevant Literature (p. 5) Several important aspects of epiphyte biology and ecology that are not investigated as part of this work, are reviewed, particularly those published on more. recently. 1.2 Epiphyte Classification and Terminology (p.11) is reviewed and the system used here is outlined and defined. A glossary of terms, as used here, is given. 5 1.1 Review of Selected, Relevant Li.terature Since the main works of Schimper were published (1884, 1888, 1898), particularly Die Epiphytische Vegetation Amerikas (1888), many workers have written on many aspects of epiphyte biology and ecology. Most of these will not be reviewed here because they are not directly relevant to the present study or have been effectively reviewed by others. A few papers that are keys to the earlier literature will be mentioned but most of the review will deal with topics that have not been reviewed separately within the chapters of this project where relevant (i.e. epiphyte classification and terminology, aspects of epiphyte synecology and CAM in the epiphyt~s). Reviewed here are some special problems of epiphytes, particularly water and mineral availability, uptake and cycling, general nutritional strategies and matters related to these. Also, all Australian works of any substance on vascular epiphytes are briefly discussed. some key earlier papers include that of Pessin (1925), an autecology of an epiphytic fern, which investigated a number of factors specifically related to epiphytism; he also reviewed more than 20 papers written from the early 1880 1 s onwards. -

Department of r.pnlnpiVal Sri PTirp.S The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date February 17, 1981 ABSTRACT The Kamloops Group is a widespread assemblage of Eocene volcanic and sedimentary rocks in south-central British Columbia. Detailed mapping of the type area near Kamloops has resulted in its subdivision into two formations and thirteen formal and informal members. The Tranquille Formation, 0-450 metres thick, consists of lacustrine sediments which grade upward into pillowed flows, hyaloclastite breccia and aquagene tuff. The overlying Dewdrop Flats Formation, with nine members, consists of up to 1000 metres of basalt to andesite phreatic breccia, flow breccia and flat-lying flows. -

GENOME EVOLUTION in MONOCOTS a Dissertation
GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. 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. -
Hybridization in the Genus Phoenix: a Review
Emir. J. Food Agric. 2013. 25 (11): 831-842 doi: 10.9755/ejfa.v25i11.16660 http://www.ejfa.info/ REVIEW ARTICLE Hybridization in the genus Phoenix: A review Muriel Gros-Balthazard* University of Fribourg, Department of Biology, Biochemistry, Chemin du Musée 10, 1700 Fribourg, Switzerland Abstract The genus Phoenix is composed of 14 species naturally distributed in the Old World. This genus comprises the date palm, Phoenix dactylifera L., cultivated for its fruits, the dates, while other species are grown for food, ornament and religious purposes. Phoenix species were, for these reasons, spread out of their natural distribution area. It is therefore common to find species not naturally sympatric, growing together, in cultivation or in the wild. Phoenix species are interfertile and crossing distinct species leads to fertile hybrid offspring (interspecific hybridization). The introduction of a species in the wild generates gene flows leading to the creation of new hybrids and has conservation implications. In cultivation, such crossings may be spontaneous or are the result of artificial pollination, as several reasons impel doing so. Crossing gives rise to beautiful hybrids and is also useful for the conservation of old palm groves threatened by pests. Moreover, artificial pollination of date palms using another Phoenix species can be of interest given the metaxenic pollen effects. In addition, this process may have some potential benefits in date palm improvements, by the creation of hybrid cultivars. Thus, an increasing need of hybrid detection and characterization exists, particularly as morphology alone is not sufficient for this task. Besides new methods such as traditional and geometric morphometrics that may bring new clues, the advent of genetic and molecular markers helps to detect hybrids, especially based on the combination of nuclear and chloroplastic data.
