Este livro foi concebido com base na nossa prática diária em estudos filogenéticos, e de forma nenhuma há a intenção de exaurir o assunto, ou que seja usado como única fonte para um aspirante a filogeneticista. Pelo contrário. Tem a intenção de ser apenas um passo, fornecendo noções básicas e simples, de modo a introduzir qualquer interessado ao fascinante mundo da filogenia.

La dolomía es un sustrato que se encuentra ampliamente distribuido por todo el globo. Su efecto geobotánico es de ámbito global. En la península Ibérica, los endemismos ligados a este tipo de roca aparecen concentrados sobre dolomías kakiritizadas situadas en las zonas de media-alta montaña de las cordilleras Béticas. Los afloramientos de dolomías se comportan como “islas ecológicas”, con una distribución fragmentada y reducida, siendo el único hábitat para aquellas especies con una intensa dolomitofilia. Por ello, debe ser considerada como un serio factor de amenaza. A esto hay que sumar el hecho de que estas especies están expuestas a la explotación mecánica de las canteras de dolomías. Por ello, las especies propias de este tipo de hábitats merecerían una consideración prioritaria, tanto en lo referente a su conservación, como en relación al conocimiento que se tiene sobre ellas. Apoyándonos en la información de la que ya se dispone sobre la región, hemos profundizado en el estudio de la flora de estos hábitats especiales, principalmente el de dolomías, intentando también estudiar su relación con el yeso. Para el estudio se ha seleccionado, de entre el alto número de endemismos existente, dos especies y un género por sus características casi únicas: Jurinea pinnata debido a la fragmentación de sus poblaciones y a su crecimiento exclusivo sobre dolomías y yesos; Convolvulus boissieri por ser una especie dolomitófila estricta pero con una amplia distribución en las cordilleras Béticas y, por último, el género Hormathophylla, género exclusivo en el mediterráneo occidental, con un claro centro de especiación en las cordilleras Béticas. Algunos representantes de este género poseen un alto grado de dolomitofilia (p.ej. H. cadevalliana), aunque también podemos encontrar especies que crecen tanto en dolomía como en yeso (H. lapeyrouseana). Aunque esta tarea se ha centrado principalmente en un estudio de la dolomitofilia desde un punto de vista principalmente genético, también nos hemos servido de otras aproximaciones tales como la fisiológica y edáfica. En el caso de los estudios genéticos, se han utilizado distintos marcadores moleculares. Por un lado, los marcadores AFLP (Amplified Fragment Lenght Polimorphisms), método fingerprinting ampliamente usado para investigar la diversidad genética y la estructura poblacional de las especies vegetales presentes sobre sustratos edáficos especiales fragmentados. Además, hemos usado secuencias de ADN cloroplástico, ampliamente empleadas tanto en estudios filogenéticos como filogeográficos. También hemos recurrido al uso de secuencias de ADN ribosómico nuclear. Este tipo de secuencia ha sido útil en el estudio de plantas adaptadas a distintos tipos de sustrato, en la distinción de ecotipos, o de sus filogenias.

In recent years, the use of molecular data to build phylogenetic trees and sophisticated computer-aided techniques to analyze them have led to a revolution in the study of cospeciation. Tangled Trees provides an up-to-date review and synthesis of current knowledge about phylogeny, cospeciation, and coevolution. The opening chapters present various methodological and theoretical approaches, ranging from the well-known parsimony approach to "jungles" and Bayesian statistical models. Then a series of empirical chapters discusses detailed studies of cospeciation involving vertebrate hosts and their parasites, including nematodes, viruses, and lice. Tangled Trees will be welcomed by researchers in a wide variety of fields, from parasitology and ecology to systematics and evolutionary biology. Contributors: Sarah Al-Tamimi, Michael A.

Phylogeography is a discipline concerned with various relationships between gene genealogies—phylogenetics—and geography. This book captures the conceptual and empirical richness of the field, and also the sense of genuine innovation that phylogeographic perspectives have brought to evolutionary studies.

The long-awaited revision of the industry standard on phylogenetics Since the publication of the first edition of this landmark volume more than twenty-five years ago, phylogenetic systematics has taken its place as the dominant paradigm of systematic biology. It has profoundly influenced the way scientists study evolution, and has seen many theoretical and technical advances as the field has continued to grow. It goes almost without saying that the next twenty-five years of phylogenetic research will prove as fascinating as the first, with many exciting developments yet to come. This new edition of Phylogenetics captures the very essence of this rapidly evolving discipline. Written for the practicing systematist and phylogeneticist, it addresses both the philosophical and technical issues of the field, as well as surveys general practices in taxonomy. Major sections of the book deal with the nature of species and higher taxa, homology and characters, trees and tree graphs, and biogeography—the purpose being to develop biologically relevant species, character, tree, and biogeographic concepts that can be applied fruitfully to phylogenetics. The book then turns its focus to phylogenetic trees, including an in-depth guide to tree-building algorithms. Additional coverage includes: Parsimony and parsimony analysis Parametric phylogenetics including maximum likelihood and Bayesian approaches Phylogenetic classification Critiques of evolutionary taxonomy, phenetics, and transformed cladistics Specimen selection, field collecting, and curating Systematic publication and the rules of nomenclature Providing a thorough synthesis of the field, this important update to Phylogenetics is essential for students and researchers in the areas of evolutionary biology, molecular evolution, genetics and evolutionary genetics, paleontology, physical anthropology, and zoology.
