The unique chromosome dynamics of meiosis have fascinated scientists for well over a century, but in recent years there has been a proliferation of new data concerning the pairing, recombination, and segregation of chromosomes. In Meiosis, expert researchers explore recent advances in three main areas: quantitative genetic methods for analysis of homologous recombination and chromosome pairing, development of direct physical assays for DNA intermediates and products of recombination, and cytological methods for characterizing chromosome behaviors and the patterns by which specific proteins associate with meiotic chromosomes. Meiosis: Volume 1, Molecular and Genetic Methods details methods for culturing and manipulating commonly used model organisms and protocols for detecting and quantifying meiotic recombination events through genetic and physical analysis of DNA-DNA or Protein-DNA interactions. Methods are provided for studies in yeasts, plants, and animals, including mouse and human. Composed in the highly successful Methods in Molecular Biology(tm) series format, each chapter contains a brief introduction, step-by-step methods, a list of necessary materials, and a Notes section which shares tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Meiosis: Volume 1, Molecular and Genetic Methods is an essential guidebook, providing up-to-date and critical new protocols for the study of meiotic chromosome dynamics.

Symbioses and Stress centers on the question of how organisms in tight symbiotic associations cope with various types of abiotic and biotic stress. In its original sense, symbioses cover all kinds of interactions among unrelated organisms, whereas in a narrower concept, the term is often referred to as mutualism. Evolutionary biology recognizes symbiosis as an integrative process, and most fundamental evolutionary innovations arose from cooperative symbioses. Mutualisms contribute to stress tolerance, ecosystem stability, and evolutionary radiation of cooperating organisms. Modern eukaryotic cells are the result of the endosymbiotic union of prokaryotic ancestors as well as diverse exosymbiotic associations. This cooperative aggregation appears more successful than its independent parts. This new book presents functional and evolutionary aspects of mutually beneficial symbioses among unrelated organisms.

Dieses inspirierende und motivierende Lehrbuch zeichnet fächerübergreifend ein beeindruckendes Gesamtbild der biologischen Vielfalt. Spannende Aspekte der Evolution der Erde und des Lebens werden durch interdisziplinäre Verknüpfung geowissenschaftlicher und biowissenschaftlicher Aspekte aus einer ganz neuen Perspektive anschaulich vermittelt. Der Schwerpunkt liegt hierbei – unter Einbeziehung aktuellster wissenschaftlicher Erkenntnisse – auf dem Verständnis von Konzepten und Mechanismen. Dieses Buch richtet sich an Studierende der Bio- und Geowissenschaften und an alle an der Vielfalt des Lebens interessierten Leser. Das innovative Lehrbuchkonzept regt – gleichzeitig als Lesebuch, Bilderbuch und Lexikon der organismischen Biologie – sowohl Anfänger als auch Fortgeschrittene zu einem visuellen und intuitiven Lernen an. Jede Doppelseite bietet ein in sich geschlossenes, anschaulich bebildertes Kapitel mit themenbezogenem Glossar und weiterführenden Verweisen. Für Dozenten und Lehrer, für Schule und Hochschule bietet dieses Buch ein reichhaltiges Nachschlagewerk und einen umfassenden Fundus an didaktisch durchdachten und lernfreundlich illustrierten Lehrmaterialien. Der Inhalt reicht - von der Entstehung der Erde über die geowissenschaftlichen Rahmenbedingungen und die Verknüpfung zwischen biologischer und geologischer Evolution bis zur Entstehung des Menschen, - von grundlegenden Mechanismen der Entstehung und Erhaltung der Diversität bis zur globalen Verteilung der heutigen Biodiversität, - von den Anfängen der biologischen Systematik in der griechischen Philosophie und der Bibel über die darwinsche Evolution und die Struktur und Funktion von Arten und Organismen bis zu den modernen Erkenntnissen der Megasystematik und Phylogenie. Mit diesem einzigartigen Konzept verschafft dieses Lehrbuch einen soliden Überblick über die Erdgeschichte und Biodiversität. Die Verknüpfung der verschiedenen Fachdisziplinen fördert das Verständnis übergeordneter Prinzipien und naturwissenschaftlicher Zusammenhänge. Die Autoren: Prof. Dr. Jens Boenigk und Dr. Sabina Wodniok sind Dozenten für Biodiversität und Botanik an der Universität Duisburg-Essen.

With the development of fungal transformation systems and the deciphering of an increasing number of fungal genomes, this diverse clade of heterotrophic eukaryotic organisms has proven to be ideal for molecular work and highly serviceable as model systems to study basic processes with results that are applicable to many organisms, including humans. In Molecular and Cell Biology Methods for Fungi, experts in the field provide an up-to-date set of practical protocols covering a range of frequently used methods used to study molecular and cellular aspects of fungal biology. The included classical protocols such as transformation systems and traditional protein analysis methods, which have been widely used for many years, alongside the most advanced techniques such as genome amplification, whole genome knockout methods, and sophisticated in vivo imaging techniques will prove to be easily adaptable and useful in a wide range of species. Written in the highly successful Methods in Molecular Biology™ series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Comprehensive and up-to-date, Molecular and Cell Biology Methods for Fungi seeks to provide cutting-edge techniques in order to aid both experienced fungal research laboratories as well as those that are interested in using fungi as hosts to study their favorite genes.

This book examines an important paradigm shift in biology: Plants and animals, traditionally viewed as individuals, are now considered to be complex systems and host to a plethora of microorganisms. After first presenting historical aspects of microbiota research, bacterial compositions of individual microbiomes and the critical analysis of current methods, the book discusses how microbial communities inside the human body are profoundly affected by numerous factors, such as macro- and micro-nutrients, physical exercise, antibiotics, gender and age. As described by current research, the author highlights how microbiomes contribute to the fitness of the host by providing nutrients, inhibiting pathogens, aiding in the storage of fat during pregnancy, and contributing to development and behavior. The author not only focusses on prokaryotic components in microbiomes, but also addresses single-cell eukaryotes and viruses. This follow-up to the successful book The Hologenome Concept: Human, Animal and Plant Microbiota, published in 2013, provides a contemporary overview of microbiomes. It appeals to anyone working in the life sciences and biomedicine.
