University Micrdnlms International 300 N INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand comer of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again— beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. University Micrdnlms International 300 N. Zeeb Road Ann Arbor, Ml 48106 8400300 Smoot, Edith L.

At many levels in the hierarchy of plant life, it will be impossible to develop an adequate understanding of plant phylogeny without taking into account the additional diversity provided by fossil plants. This is especially the case for relatively deep divergences among extant lineages that have a long evolutionary history and in which much of the relevant diversity has been lost by extinction. In such circumstances, attempts to integrate data and interpretations from extant and fossil plants stand the best chance of success. For this to be possible, what will be required is meticulous and thorough descriptions of fossil material, thoughtful and rigorous analysis of characters, and careful comparison of extant and fossil taxa, as a basis for determining their systematic relationships. Key words: angiosperms; fossils; paleobotany; phylogeny; spermatophytes; tracheophytes. Most biological processes, such as reproduction or growth distic context, neither fossils nor their stratigraphic position and development, can only be studied directly or manipulated have any special role in inferring phylogeny, and although experimentally using living organisms. Nevertheless, much of more complex models have been developed (see Fisher, 1994; what we have inferred about the large-scale processes of plant Huelsenbeck, 1994), these have not been widely adopted.

  • System Klasyfikacji Organizmów
    1 SYSTEM KLASYFIKACJI ORGANIZMÓW Nie ma dziś ogólnie przyjętego systemu klasyfikacji organizmów. Nie udaje się osiągnąć zgodności nie tylko w odniesieniu do zakresów i rang poszczególnych taksonów, ale nawet co do zasad metodologicznych, na których klasyfikacja powinna być oparta. Zespołowe dzieła przeglądowe z reguły prezentują odmienne i wzajemnie sprzeczne podejścia poszczególnych autorów, bez nadziei na consensus. Nie ma więc mowy o skompilowaniu jednolitego schematu klasyfikacji z literatury i system przedstawiony poniżej nie daje nadziei na zaakceptowanie przez kogokolwiek poza kompilatorem. Przygotowany został w oparciu o kilka zasad (skądinąd bardzo kontrowersyjnych): (1) Identyfikowanie ga- tunków i ich klasyfikowanie w jednostki rodzajowe, rodzinowe czy rzędy jest zadaniem specjalistów i bez szcze- gółowych samodzielnych studiów nie można kwestionować wyników takich badań. (2) Podział świata żywego na królestwa, typy, gromady i rzędy jest natomiast domeną ewolucjonistów i dydaktyków. Powody, które posłużyły do wydzielenia jednostek powinny być jasno przedstawialne i zrozumiałe również dla niespecjalistów, albowiem (3) podstawowym zadaniem systematyki jest ułatwianie laikom i początkującym badaczom poruszanie się w obezwładniającej złożoności świata żywego. Wątpliwe jednak, by wystarczyło to do stworzenia zadowalającej klasyfikacji. W takiej sytuacji można jedynie przypomnieć, że lepszy ułomny system, niż żaden. Królestwo PROKARYOTA Chatton, 1938 DNA wyłącznie w postaci kolistej (genoforów), transkrypcja nie rozdzielona przestrzennie od translacji – rybosomy w tym samym przedzia- le komórki, co DNA.

    CHAPTER 1 Plant diversity has evolved and is evolving on the earth today according to the processes of natural selection. All basic "body plans" of vascular plants were in existence by the Early Carboniferous, approximately 340 million years ago, and each major radiation occupied a particular habitat type, for example, wetland versus terra firma, pristine versus disturbed environments. Today the great spe- cies diversity we see on theplanetis dominated by just a few of these hasicplant types. This chapter sets the stage to understanding the origin and radiation of plant diversity on the earth before the significant influence of humans. The im- plication is that plants may become more diverse in the number of species level over time, but less diverse in overall form. The history of life tells us that plants that are dominant and diverse today will certainly be inconspicuous or even ex--' tinct in the distant future. EVOLUTION OF LAND PLANT DIVERSITY MAJOR INNOVATIONS AND LINEAGES THROUGH TIME William A. DiMichele and Richard M. Bateman PLANT DIVERSITY VIEWED through the lens of deep time takes on a con- siderably different aspect than when examined in the present. Although the fossil record captures only fragments of the terrestrial world of the past 450 million years, it does indicate clearly that the world of today is simply a passing phase, the latest permutation in a string of spasmodic changes in the ecological organization of the terrestrial biosphere. The pace of change in species diversity and that of ecosystem structure and composition have followed broadly parallel paths, unquestionably related but not always changing in unison.

  • An Overview of the Fossil Record of Climbers: Bejucos, Sogas, Trepadoras, Lianas, Cipós, and Vines
    Rev. bras. paleontol. 12(2):149-160, Maio/Agosto 2009 © 2009 by the Sociedade Brasileira de Paleontologia doi:10.4072/rbp.2009.2.05 AN OVERVIEW OF THE FOSSIL RECORD OF CLIMBERS: BEJUCOS, SOGAS, TREPADORAS, LIANAS, CIPÓS, AND VINES ROBYN J. BURNHAM Museum of Paleontology, University of Michigan 1109 Geddes Avenue, Ann Arbor, MI 48109-1079, USA. [email protected] ABSTRACT – One of the most obvious life forms in tropical forests today is the liana, which laces together tree canopies and climbs the dark interiors of forests with snake-like stems. Lianas are ecologically important in extant, forested ecosystems, both intact and disturbed. Their contribution to forest diversity, food resources, structural complexity, and plant-animal interactions are recognized, but rarely studied. Climbers (woody lianas and herbaceous vines) are viewed as everything from diversity contributors to forest growth inhibitors by modern ecologists and systematists. Climbers take advantage of the structural support of trees to invest proportionately more in vegetative and reproductive organs, resulting in proliferation at the individual and species level. Today the climbing habit is dominated by angiosperm species, with only a minor contribution from ferns plus a single non-angiosperm seed plant genus, Gnetum. This contribution reports the establishment of the newly established database, Fossil Record of Climbers (FRC) that documents more than 1100 records of climbing plants from the Paleozoic to the Quaternary using published literature on the fossil record. The diversity of climbers in the fossil record prior to the evolution of angiosperms is explored, posing the hypothesis that climbers of the past had a similarly important role in tropical forests, at least in the Paleozoic.

    MORPHOLOGICAL CLADISTIC ANALYSIS OF THE CORDAITEAN CONES AND IM PLICATIONS FOR PLANT LINEAGES A Thesis by JULIAN EDUARDO CORREA Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Anne Raymond Committee Members, Thomas Olszewski James Woolley Head of Department, Rick Giardino August 2015 Major Subject: Geology Copyright 2015 Julian Eduardo Correa ABSTRACT The cordaiteans were a group of Carboniferous and Permian woody plants, which thrived in wetlands and terra firma habitats. Cordaitean cones from wetland habitats are exquisitely well preserved and contain a suit of characters that make their fossils prime candidates for cladistic analysis; historically, there are more male cones than female cone. Cordaitean morphological characteristics make this clade a possible precursor lineage of modern conifer and gnetalean lineages. However, the exact relation between fossil seed- plant clades and modern gymnosperm groups remains enigmatic. The resent discovery of a bisexual cordaitean cone calls into question the relationship between cordaiteans, gnetaleans and angiosperms. This study performs three cladistic analyses in order to find the relations of taxa within the cordaitean clade and other early plant lineages using primarily PAUP* and TNT. An analysis of male only cones provides a phylogram for the relations between the cordaitean taxa; the results also suggest a bisexual ancestry for the clade. A second analysis attempted to introduce the morphologically distinct female cones; the results produce a similar strict consensus tree. However, many of the female cones do not pair with their associated male cones identified in ‘whole-plant’ reconstructions of cordaitean lineages.
