Flowering Plants of Amazonian Ecuador - A Checklist
This textbook gives an introduction to genetics and genomics at the college level. It contains a chapter on human genetic evolution. Other chapters treat transmission genetics, molecular genetics and evolutionary genetics and provide an understanding of the basic process of gene transmission, mutation, expression and regulation.
The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrialimpacts, and other features.The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied excl...
Thoroughly revised and updated with the latest data from this every changing field, the Eighth Edition of Genetics: Analysis of Genes and Genomes provides a clear, balanced, and comprehensive introduction to genetics and genomics at the college level. Expanding upon the key elements that have made this text a success, Hartl has included updates throughout, as well as a new chapter dedicated to genetic evolution. He continues to treat transmission genetics, molecular genetics, and evolutionary genetics as fully integrated subjects and provide students with an unprecedented understanding of the basic process of gene transmission, mutation, expression, and regulation. New chapter openers include a new section highlighting scientific competencies, while end-of-chapter Guide to Problem-Solving sections demonstrate the concepts needed to efficiently solve problems and understand the reasoning behind the correct answer.
This text approaches floral odour analysis using thin layer chromatography. It includes illustrations of flora morphology and anatomy.
Fernanda Antunes Carvalho addresses an issue of key importance to the field of systematics, namely how to foster taxonomic work and the dissemination of scientific knowledge about species by taking full advantage of electronic data and bioinformatics tools. The first part focuses on the development of an electronic monograph of the papaya family (Caricaceae) using existing infrastructures of Information Technology (IT) and bioinformatic tools that together set the stage for a new era of systematics. Based on the plastid and nuclear DNA data, the author inferred historical processes in the second part that may have shaped the evolution of the Caricaceae and explain their current geographic distribution. The last part is dedicated to the evolution of chromosome numbers in the Caricaceae and includes counts for species from three genera (Cylicomorpha, Horovitzia, Jarilla) that have never been investigated before.

An accessible modern guide to Darwin's masterwork Charles Darwin's Origin of Species is one of the most widely cited books in modern science. Yet tackling this classic can be daunting for students and general readers alike because of Darwin's Victorian prose and the complexity and scope of his ideas. The "Origin" Then and Now is a unique guide to Darwin's masterwork, making it accessible to a much wider audience by deconstructing and reorganizing the Origin in a way that allows for a clear explanation of its key concepts. The Origin is examined within the historical context in which it was written, and modern examples are used to reveal how this work remains a relevant and living document fo...
