This book provides a first synthetic view of an emerging area of ecology and biogeography, linking individual- and population-level processes to geographic distributions and biodiversity patterns. Problems in evolutionary ecology, macroecology, and biogeography are illuminated by this integrative view. The book focuses on correlative approaches known as ecological niche modeling, species distribution modeling, or habitat suitability modeling, which use associations between known occurrences of species and environmental variables to identify environmental conditions under which populations can be maintained. The spatial distribution of environments suitable for the species can then be estimated: a potential distribution for the species. This approach has broad applicability to ecology, evolution, biogeography, and conservation biology, as well as to understanding the geographic potential of invasive species and infectious diseases, and the biological implications of climate change. The book lays out conceptual foundations and general principles for understanding and interpreting species distributions with respect to geography and environment. Focus is on development of niche models. While serving as a guide for students and researchers, the book also provides a theoretical framework to support future progress in the field.Less

The biodiversity of zooplankton and zoobenthos decreases towards high latitudes, though the two poles have different species compositions despite environmental similarities in temperature, habitat structure, and light cycle. Different geological history and accessibility largely explain the faunal differences between the poles. While some species live close to their environmental tolerance in the cold polar regions, others have adapted to life at low temperatures. This chapter describes the unique cold-water communities of zooplankton and zoobenthos in the two polar regions. It reviews the most important factors that define the zoogeography and diversity of freshwater invertebrates in the Arctic and Antarctic, and provides detail on the ecology and life-history of some key zooplankton and aquatic insects. The final section considers how climate change, especially elevated temperature and increase in UV radiation, are altering high-latitude aquatic invertebrate communities.Less

The broad arc of islands north of Australia, extending from Indonesia east towards the central Pacific, is home to a set of human populations whose diversity is unsurpassed elsewhere. Approximately 20% of the world's languages are spoken here, and the biological and genetic heterogeneity among the groups is also extraordinary. This book describes the origins of the genetic and linguistic variation there. It lays out the very complex structure of the variation within and among the islands in this relatively small but important region. This book applies genetic analyses to an intensively sampled set of populations, and subjects these and complementary linguistic data to a variety of phylogenetic analyses. This reveals a number of heretofore unknown ancient Pleistocene genetic variants that are only found in these island populations, and identifies the genetic footprints of more recent migrants from Southeast Asia who were the ancestors of the Polynesians. Finally, a number of explanatory models are tested to see which best account for the observed pattern of genetic variation. The results indicate that a number of commonly used models of evolutionary divergence and biogeography are overly simple in their assumptions, and that human diversity often has accumulated in very complex ways.Less

This introductory chapter describes the outline, focus, and themes of the book. The book describes the genetic and linguistic diversity in the key region of Northern Island Melanesia. Recurrent themes of the book are laid out. These are: the influence of the island biogeography (a series of stepping-stone islands extending from Southeast Asia into the Pacific); the dynamics of small populations (even some of the larger islands had carrying capacities of under 1,000 people in pre-Neolithic times); very limited marital migration distances in inland (bush) communities vs. more extensive marital migration rates along shoreline communities; intensifying mobility after the isolation of initial settlement, aided by better seafaring technology in the Holocene; and later immigration of distinct peoples from Island Southeast Asia, who spoke Austronesian (Oceanic) languages and settled along the shorelines and the small islands, so that language distinctions are associated to a degree with the pattern of diversity. The succeeding chapters are summarized.Less

This chapter examines how the process of ecological niche evolution and diversification helps us better understand ecology, biogeography, and biodiversity. It first considers how species respond to changes in the environmental substrate on which the niches are manifested before discussing the concept of niche conservatism as well as tests of conservatism in areas such as species invasions and comparison of the ecological niche requirements of sister–species pairs. It then explores how temporal change in niche dimensions occurs, how it can be studied, and what can be learned. It also describes some of the challenges associated with applications of ecological niche modeling in the realm of evolution and concludes by outlining future directions for research.Less

This chapter looks at energy flow through the community (primary and secondary production) and food web dynamics. It includes a brief examination of the diversity-stability idea. A detailed flow diagram of the Serengeti ecosystem, along with modelling attempts on this system are examined. This dynamic, interacting web brings to light the importance of cascading interactions (e.g., rinderpest-wildebeest-green grass-dry grass-fire-trees-giraffes), and therefore the multiple interconnection of species. Mention is made of ‘keystone’ species. There is a section on ‘assembly rules’ for savannah communities, including body-size distributions for grazing and browsing ungulates. This section ends with an exploration of virtual island biogeography (protected areas) and the long-term predictions for species numbers. Can ideas from ‘island biogeography’ help us to design National Parks and Nature Reserves? This leads onto conservation issues. The conservation issues for savannahs centre around tourism, hunting (both for trophies and bush meat), and the conflicts between farmers/ranchers and wildlife. This chapter ends with an examination of these issues.Less

The present‐day distribution of ants reflects the influence of geography, geology, and climate on the origin, diversification, and spread of a lineage. Though the process is complex and often difficult to reconstruct for a given taxon, two important overall patterns emerge: taxa are neither randomly nor uniformly distributed across the earth, and endemic taxa are clustered in particular regions. The greatest ant diversity and endemicity are found in the tropics and the Gondwanaland fragments of South America, Africa, and Australia. Lines of inquiry that combine exhaustive inventories, taxonomic revisions, and phylogenetics will enable a more rigorous approach to the study of biogeography. Islands offer a model system to explore these questions. Due to their range in size, origin, degree of isolation, and habitat types, the south‐west Indian Ocean islands are an ideal model system to explore the relative impact of biogeographic factors on species diversity.Less

Biogeography is a naturally integrative field of study that helps explore data on the diversity, phylogeny, and distribution of organisms to reveal the biological and geographical history of Earth. This book aims to establish comparative biogeography, a method that uses the naturally hierarchical phylogenetic relationships of clades to discover the biotic area relationships among local and global biogeographic regions. It details the foundations of comparative biogeography and how they relate to two types of biogeographic investigation: systematic biogeography and evolutionary biogeography. The book reviews current methods of biogeography, especially with regard to how they relate to the goal of biotic area classification; addresses the relationship between geology and biological distribution; and attempts to discover what triggers evolution of biodiversity and distribution patterns.Less

The largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. This review takes the reader from Darwin's early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The chapters furnish a discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change.Less

This book offers a concise but comprehensive introduction to desert ecology, and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although conservation and experimental aspects are also considered. Deserts are defined by their arid conditions; a consequence of this aridity is that most of the area occupied by desert is barren and monotonous, leading many people to regard it as wasteland. However, deserts are widespread and represent surprisingly biodiverse environments, although it is the relative simplicity of these ecosystems that makes them more tractable for study than more complex environments. In these resource-poor locations, natural selection is working at its greatest extreme, and provides some of the best-known examples of Darwinian selection. The Biology of Deserts includes a wide range of ecological and evolutionary issues, including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation.Less

More
The first book to deal in an integrated manner the full range of terrestrial, freshwater, and marine ecosystems that occur in Costa Rica, Costa Rican Ecosystems provides an overview of Costa Rica’s main ecosystems by compiling information about their physical settings, biogeography, species diversity, and much more. Rather than follow a technical or clinical approach with a hierarchical categorization of ecosystems, Costa Rica’s dense ecology is explored in a “journey-wise” sequence that provides familiarity and understanding of the country’s full, varied range of intergrading seascapes and landscapes. The book begins with three introductory chapters focusing on Costa Rica’s climate, geology, and soils to provide an understanding of the medium in which its ecology has developed, and then proceeds with a presentation of each of the country’s ecosystems. These chapters review the research to provide a detailed description of each ecosystem, from its location, extent, and general function, to its characteristic species and the ways in which these species interact. The authors provide a summary of the effects that humans have had on the environment in each case, as well as the history, challenges, and successes of the relevant conservation efforts. This book, a culmination of decades of scientific achievement and experience, provides an intellectual template upon which sustainability can be built for Costa Rica and a model for an ecosystems overview that all nations should aspire to and emulate.Less

Tropical East Asia is home to over 1 billion people and faces massive human impacts from its rising population and rapid economic growth. It has already lost more than half of its forest cover and has the highest rates of deforestation and logging in the tropics. Hunting and the trade in wildlife products threaten all its large and many smaller vertebrates. Despite these problems, the region still supports an estimated 15–25 per cent of global terrestrial biodiversity and is thus a key focus for global conservation. This book therefore deals with plants, animals, and the ecosystems they inhabit, as well as the diverse threats to their survival and the options for their conservation. It provides the background knowledge of the region’s ecology needed by both specialists and non-specialists to put their own work into a broader context. The first edition was the first book to describe the terrestrial ecology of the entire East Asian tropics and subtropics, from southern China to western Indonesia, and the second edition extended the coverage to include the very similar ecosystems of Northeast India, Bangladesh, and Bhutan. The third edition updates the contents and gives more prominence to Anthropocene impacts and possible conservation responses. The accessible style, comprehensive coverage, and engaging illustrations make this advanced textbook an essential read for senior undergraduate and graduate-level students studying the terrestrial ecology of the East Asian tropics, as well as an authoritative reference for professional ecologists, conservationists, and interested amateurs worldwide.Less

While some rigorous scholarship has recently appeared questioning Bernier's significance, his racial theory is seldom placed in his context as a Gassendian natural philosopher who was, in particular, intent to bring his own brand of modern, materialistic philosophy to bear in his experiences in the Moghul Empire in Persia and northern India. The chapter argues that Bernier's principal innovation was to effectively decouple the concept of race from considerations of lineage, and instead to conceptualize it in biogeographical terms in which the precise origins or causes of the original differences of human physical appearance from region to region remain underdetermined.Less

We find the patterns intriguing for several reasons. This is not because we are surprised by competition as a process. There is abundant evidence that similar species compete. What is interesting is the scale and extent over which competition plays out. At issue was not whether competition is intensive enough to affect species abundance at small scales, but rather was it extensive enough to shape the large-scale patterns of nature? Our maps discuss patterns across millions of square kilometers. Our impression of papers in community ecology was that this debate led to small-scale, experimental studies with fewer species, eschewing the issues at larger scales. If so, that would be unfortunate. Biogeographical patterns have exercised considerable historical significance. The checkerboard of the Galápagos mockingbirds and patterns of mutual exclusivity in the Amazon and insular Southeast Asia were vital clues that gave Darwin and Wallace their ideas about evolution. We assert that community ecologists now have powerful software and hardware tools to uncover subtle patterns in nature.Less

This chapter presents the biogeography of the House Finches, which has an extensive range across North America. House Finches were accidentally established by people on the east coast in the mid-20th century and had spread throughout the eastern U.S. and Canada by the late 20th century. Across their native range in western North America, taxonomists recognize eighteen subspecies of House Finches. Across their range, male House Finches vary in the size of their red throat/breast patch as well as in the brightness of red coloration.Less

This chapter is designed to push community ecologists to re-consider how they are using phylogenetic information in their research. The research path that I present as a much more interesting, valuable and viable phylogenetic approach to community ecology is not novel. It has been running in parallel with occasional cross-pollination with the phylogenetic proxy literature for decades. Furthermore, this approach has the ability to make more meaningful inferences regarding the intersection of evolutionary history, biogeography and community ecology. Lost in the critiques of the phylogenetic proxy approach that focus on the proxy itself and inferring a process from a pattern is one of the more damning critiques of this literature—it has largely failed to fully integrate evolutionary history and community ecology. Without knowing such information it becomes hard to identify any generalities emerging across taxa and ecosystems, which would greatly help in the formation of a true synthesis between evolution and community ecology.Less

Here, I begin with a discussion of the hypothesized role of phylogenetic niche conservatism and the latitudinal gradient as well as the cradles versus museums dichotomy regarding the origins of tropical diversity. Lastly, I will discuss priority effects, ecological opportunity and how phylogenetic information may be used in these contexts to understand the evolution of assemblages and biodiversity. Ideally, I would like the reader to take away from this chapter that phylogenies have a place in ecology beyond comparative methods and community ecology and that they provide a fundamentally important framework for many of the major pressing questions facing ecology.Less

The perspective I have attempted to outline in this book is that phylogenies are not a magical cure for all that ails ecology nor are they part of some passing fad. Rather, they are useful in many instances and less than useful other instances. Furthermore, I have argued that phylogenies are, at present, often utilized in ecology in ways that do not maximize their power and in some cases used in a way that will lead to flawed or very incomplete inferences. By outlining the historical development and emerging concepts and tools in phylogenetic ecology, I have aimed to rationalize why the field has ended up in its current state and to highlight how the course can be adjusted to maximize the utilizes of phylogenies in ecology. The course adjustment or remodeling in phylogenetic ecology should begin with five foci I introduced in Chapter 1. I revisit these foci in this chapter and use them to shine a light on the way forward for a healthy and useful phylogenetic ecology.Less

Evolutionary biogeography lies at the intersection between two sets of highly dynamic processes. One set dictates the physical environment, in which changes in size, isolation, and overall suitability for supporting life, tend to occur in cycles of different frequencies. The second set of processes shapes the ecological and evolutionary trajectories of organisms that inhabit the physical environment. The chapter reviews some of the major biogeographic patterns, and summarize theories that have been developed to account for the different patterns, including vicariance, dispersal, island biogeography, ecophylogenetics, niche theory, and neutral theory. The chapter develops propositions for a synthetic theory of biogeography that integrates the dynamic nature of geographic space with the spatial and temporal dynamics of biodiversity. Specifically, it outlines how geological and climatological cycles lead to periods of isolation and fusion of organisms inhabiting a given area, with associated effects speciation and extinction. A synthetic theory of biogeography requires cross-domain consideration of how the cyclical nature of change in the physical environment affects the ecological and evolutionary processes of different taxa and at different scales of space and time.Less
