Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.

This brief book is dedicated to the quantitative analyses and systematic discussion of spatial biodiversity and biogeographic patterns in the Asia‐pacific region comprised of China, India and adjacent countries. The book is split into two sections. The first section presents readers with detailed statistical methods to conduct spatial macro‐biodiversity and biogeography analyses. Step-by-step instructions on how to perform these statistical methods by using the statistical program R are also provided. In the second part, different quantitative case studies are presented covering several topics, including phylogenetics, spatial statistics, multivariate statistics and ecological genomics. Each case study concludes with a detailed interpretation of the quantitative results and how these results are relevant to local and regional ecological processes. This reference is suitable for academics interested in biostatistics biodiversity and ecological studies specific to the Asia Pacific region and China.

Despite often violent fluctuations in nature, species extinction is rare. California red scale, a potentially devastating pest of citrus, has been suppressed for fifty years in California to extremely low yet stable densities by its controlling parasitoid. Some larch budmoth populations undergo extreme cycles; others never cycle. In Consumer-Resource Dynamics, William Murdoch, Cherie Briggs, and Roger Nisbet use these and numerous other biological examples to lay the groundwork for a unifying theory applicable to predator-prey, parasitoid-host, and other consumer-resource interactions. Throughout, the focus is on how the properties of real organisms affect population dynamics. The core of the book synthesizes and extends the authors' own models involving insect parasitoids and their hosts, and explores in depth how consumer species compete for a dynamic resource. The emerging general consumer-resource theory accounts for how consumers respond to differences among individuals in the resource population. From here the authors move to other models of consumer-resource dynamics and population dynamics in general. Consideration of empirical examples, key concepts, and a necessary review of simple models is followed by examination of spatial processes affecting dynamics, and of implications for biological control of pest organisms. The book establishes the coherence and broad applicability of consumer-resource theory and connects it to single-species dynamics. It closes by stressing the theory's value as a hierarchy of models that allows both generality and testability in the field.

Population genetics has made great strides in applying statistical analysis and mathematical modeling to understand how genes mutate and spread through populations over time. But real populations also live in space. Streams, mountains, and other geographic features often divide populations, limit migration, or otherwise influence gene flow. This book rigorously examines the processes that determine geographic patterns of genetic variation, providing a comprehensive guide to their study and interpretation. Geographical Genetics has a unique focus on the mathematical relationships of spatial statistical measures of patterns to stochastic processes. It also develops the probability and distribution theory of various spatial statistics for analysis of population genetic data, detailing exact methods for using various spatial features to make precise inferences about migration, natural selection, and other dynamic forces. The book also reviews the experimental literature on the types of spatial patterns of genetic variation found within and among populations. And it makes an unprecedented strong connection between observed measures of spatial patterns and those predicted theoretically. Along the way, it introduces readers to the mathematics of spatial statistics, applications to specific population genetic systems, and the relationship between the mathematics of space-time processes and the formal theory of geographical genetics. Written by a leading authority, this is the first comprehensive treatment of geographical genetics. It is a much-needed guide to the theory, techniques, and applications of a field that will play an increasingly important role in population biology and ecology.

Ernst Haeckel (1834 - 1919) war ein deutscher Zoologe, Philosoph und Freidenker. In seinem hier vorliegenden Werk hat er sich den Protisten angenommen. Er beschreibt diese ein- bis mehrzelligen Lebewesen und ihren Lebensraum. Am Ende findet sich ein System, in dem die Protisten verschiedenen Klassen zugeordnet sind. Sorgfaltig bearbeiteter Nachdruck der Originalausgabe von 1878.

Das Buch für naturwissenschaftlich interessierte Leser, die sich Gedanken machen über die anstehenden Probleme einer zahlenmäßig rasch zunehmenden Weltbevölkerung. Das Buch klärt über den bisher allgemein kaum bekannten Nutzen der sogenannten Großpilze auf. Es sind Pilze, die man sonst von Spaziergängen in Wald und Wiese kennt und die man im Handel kaufen kann. Wie können Großpilze dazu beitragen die Menschheit zu retten?Können Ernährungsprobleme in armen Ländern Afrikas durch Großpilze gelöst werden?Gelingt eine Revitalisierung ganzer geschädigter Wälder?Und was haben Pilze auf dem Mars zu suchen?Diese und weitere spannende Fragen werden im Verlauf der Kapitel beantwortet. Die Leser bekommen Einblicke in die Geheimnisse und Arbeitsweisen einer Wissenschaft, die, wie auch Pilze, im Verborgenen aktiv ist, deren Bedeutung rapide steigt, obwohl sie bisher nur von relativ wenigen Forschern betrieben wird.
