Allee effects are broadly defined as a decline in individual fitness at low population size or density, that can result in critical population thresholds below which populations crash to extinction. As such, they are very relevant to many conservation programmes, where scientists and managers are often working with populations that have been reduced to low densities or small numbers. There are a variety of mechanisms that can create Allee effects, including mating systems, predation, environmental modification, and social interactions among others. The abrupt and unpredicted collapses of many exploited populations is just one illustration of the need to bring Allee effects to the forefront of conservation and management strategies. This book provides an overview of the topic, collating and integrating a widely dispersed literature from various fields: marine and terrestrial, plant and animal, theoretical and empirical, academic and applied.

This book is a collection of nineteen chapters where summaries of major ecological and evolutionary questions have been asked and responded using dragonflies and damselflies as study subjects. Each chapter is written by a well-respected scientist. The topics covered are: demography, population and community ecology, life-history, distribution, abundance, migration, conservation, applied use, predator-prey interactions, mating isolation, lifetime reproductive success estimates, reproduction vs. survival, parasite-host relationships, cryptic female choice, sexual conflict, territoriality, sex-limited colour polymorphisms, sexual size dimorphism, flight performance, and wing evolution. Each chapter puts forward new data and hypothesis in relation to further ecological and evolutionary questions.Less

This book reviews a variety of evolutionary themes and uses the small terrestrial orchids of Australia to introduce and illustrate these themes. Among the topics explored are the competing ideas of biologists who use the theory of natural selection when examining possible adaptations (such as the ability of orchid flowers to attract special pollinators) and those who reject this approach, including creationists as well as the late Stephen Jay Gould. Darwin’s own ideas on the topic are reviewed as his work on adaptive plant behavior, given that orchids provide examples of flowers with moving parts. In addition, the book outlines the ability of evolutionary biologists to trace the origin and subsequent modification of complex traits like the extraordinarily unusual flowers of certain orchids. The book also employs Australian orchids to demonstrate the challenges of determining what a species is and how to preserve the biodiversity that still exists in the world.Less

More
The environment, and how humans affect it, is more of a concern now than ever. We are constantly told that halting climate change requires raising awareness, changing attitudes, and finally altering behaviors among the general public—and doing it fast. New information, attitudes, and actions, it is conventionally assumed, will necessarily follow one from the other. However, this approach ignores much of what is known about attitudes in general and environmental attitudes in particular—a huge gap lies between what we say and what we do. Solving environmental problems requires a scientific understanding of public attitudes. Like rocks in a swollen river, attitudes often lie beneath the surface—hard to see, and even harder to move or change. This book helps us read the water and negotiate its hidden obstacles, explaining what attitudes are, how they change and influence behavior. Rather than trying to change attitudes, we need to design solutions and policies with attitudes in mind. Heberlein illustrates these points by tracing the attitudes of the well-known environmentalist Aldo Leopold, while tying social psychology to real-world behaviors throughout the book. Bringing together theory and practice, this book provides a realistic understanding of why and how attitudes matter when it comes to environmental problems; and how, by balancing natural with social science, we can step back from false assumptions and unproductive, frustrating programs to work toward fostering successful, effective environmental action.Less

Mushrooms are the most wondrous inventions of the last billion years of evolutionary history on earth. Their overnight appearance is a pneumatic process, with the inflation of millions of preformed cells extending the stem, pushing earth aside, and unfolding a cap above the dewy grass. Once exposed, a mushroom's gills shed an astonishing 30,000 spores per second, delivering billions of microscopic particles into the air in a single day, cells that may be capable of spawning the largest organisms on the planet. Mushroom colonies burrow through soil and rotting wood. Some hook into the roots of forest trees and engage in mutually supportive symbioses; others are pathogens that decorate their food sources with hardened hooves and fleshy shelves. Among the staggering diversity of mushroom-forming fungi we find stranger apparitions including gigantic puffballs, phallic eruptions with revolting aromas, and tiny “bird's nests” whose spore-filled eggs are splashed out by raindrops. But it is the poisonous effects of a handful of fungal metabolites, and the powerful hallucinogenic qualities of others, which account for the central place of mushrooms in mythology and their commonest associations in Western culture. This book explains what mushrooms are (Chapter 1), how they work (Chapter 2), and what their underlying colonies do (Chapter 3); the harvesting and conservation of wild mushrooms and the cultivation of domesticated species are addressed in Chapters 4 and 5, the science of poisonous and hallucinatory fungi in Chapters 6 and 7, and deceptive claims about medicinal mushrooms in Chapter 8.Less

Hans Kruuk's previous Wild Otters was the first, and until now the only, book to cover both natural history and scientific research on behaviour and ecology of otters in Europe. The present book is a revision, rewrite, and update, now covering all species of otter in North America as well as Europe and elsewhere. Aimed at naturalists, scientists, and conservationists, in a personal style and with many illustrations, it describes the ecology and behaviour of some of the most charismatic and enigmatic mammals in our environment, as well as the research to understand their particular ecological problems. With over 650 references, there is up-to-date description of the most recent studies, including feeding ecology, foraging behaviour, relationships with prey species, and factors that limit populations, as well as social and breeding behaviour, molecular genetics, energetics, the problems of exposure to cold water, mortality, effects of pollution, and the serious, recent conservation problems. There are enchanting direct observations of the animals, as well as guidance about how and where to watch and study them, and what are the most serious questions facing researchers. From otters in the British and American lakes and rivers, to sea otters in the Pacific ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an enthusiastic, critical, and thorough approach to their fascinating existence, the science needed to understand it, and the threats to their survival.Less

All populations fluctuate stochastically, creating a risk of extinction that does not exist in deterministic models, with fundamental consequences for both pure and applied ecology. This book provides an introduction to stochastic population dynamics, combining classical background material with a variety of modern approaches, including previously unpublished results by the authors, illustrated with examples from bird and mammal populations, and insect communities. Demographic and environmental stochasticity are introduced with statistical methods for estimating them from field data. The long-run growth rate of a population is explained and extended to include age structure with both demographic and environmental stochasticity. Diffusion approximations facilitate the analysis of extinction dynamics and the duration of the final decline. Methods are developed for estimating delayed density dependence from population time series using life history data. Metapopulation viability and the spatial scale of population fluctuations and extinction risk are analyzed. Stochastic dynamics and statistical uncertainty in population parameters are incorporated in Population Viability Analysis and strategies for sustainable harvesting. Statistics of species diversity measures and species abundance distributions are described, with implications for rapid assessments of biodiversity, and methods are developed for partitioning species diversity into additive components. Analysis of the stochastic dynamics of a tropical butterfly community in space and time indicates that most of the variance in the species abundance distribution is due to ecological heterogeneity among species, so that real communities are far from neutral.Less

The Amazon is a major biome for helping to stabilize the water and temperature of its region and possibly even the whole planet. But increasingly it is subject to droughts leading to the possibility of a runaway drying into a far less diverse forest and even an emergent savannah. In essence this is a highly complex socio-ecological biome which is experiencing global interconnections over carbon emissions and food price spikes. All of this makes predictions of the tipping points for the Amazon extremely difficult to model or to manage. Turning these disturbance factors around requires regional and local scale commitment involving all communities and real incentives to conserve ecosystem services with appropriate safeguards and payments. This is a tall order as at the level of land use and forest conservation, the incentives are perverse.Less

Ecological modernization now suggests that environmental values can be attached to the state's core economic imperative, while Ulrich Beck's risk society thesis suggests an environmental attachment to the state's core legitimation imperative. These developments could add up to a conservation imperative of the state—the green state—though no state is yet close to this situation. Norway has entrenched ecological modernization in a moderate weak form. Germany is closest to a strong form of ecological modernization that, in combination with risk‐induced legitimation crisis, points the way to a more reflexive and democratic political economy. The US has the sort of movement that could facilitate such a transformation—but its state has moved in exactly the opposite direction, casting economic and environmental values in old‐fashioned conflictual terms. Even the UK at long last appears to be capable of taking on board some of the key precepts of ecological modernization and democratization.Less

It is widely believed that environmental conservation has to be guided by respect for the ‘rights’ of future generations. But it is argued in this chapter that it may not be plausible to think in terms of the ‘rights’ of future generations in general or their rights to any specific environmental assets. Future generations may well have rights when they come into existence, but these will only be rights that can be satisfied at the time. But ‘rights’ do not exhaust the whole of morality, and future generations will certainly have interests, which means that we are under moral obligation to take account of them and of the effect that our environmental policies may have on them. Thus, the problem is to predict what the main interests of future generations will be and how to weigh them up against the interests of people alive today. It is argued that this approach will lead to a very different ranking of priorities among our moral obligations to future generations.Less

Freshwater ecosystems worldwide are highly threatened. As a consequence, many dragonfly species are also threatened. The threats to them are many and varied, including invasive alien plants and habitat loss. Global climate change is also beginning to affect them, with some species changing their geographical ranges. Worldwide assessments are being made of dragonfly conservation status. They are one of the highest profile invertebrates in conservation awareness, planning, and action. One reason for this is that they are highly valued, being iconic, aesthetic, and sensitive bioindicators of landscape change. They are both important subjects in their own right as well as important role players in overall biodiversity conservation.Less

To many, Theodore Roosevelt was an exemplar of manliness and “muscular Christianity” and an exceptional public servant who led a crusade for social justice. To others, the sage of Oyster Bay was a jingoist, a nativist, a hot-tempered, unpredictable manic, and an egomaniac who put his own interests above America’s good. Roosevelt highly valued biblical morality and considered it vital to personal and public life, including politics. He downplayed doctrine and theological differences and strongly stressed the importance of good works and character. Many contemporaries called him a preacher of righteousness, and he labeled the presidency a bully pulpit, which he used to trumpet the importance of social justice, civility, and virtue. Three religious issues caused considerable controversy during Roosevelt’s tenure in office: his attempt to remove “In God We Trust” from some coins, the “Dear Maria” affair, and concerns about William Howard Taft’s Unitarianism during the 1908 presidential campaign. Christianity, especially the version espoused by turn-of-the-century Social Gospelers, played a significant role in shaping his philosophy of government. Roosevelt’s role in mediating the 1902 anthracite coal strike, “taking” Panama to build an isthmus canal, and promoting conservation illustrate how his religious commitments helped shape his policies.Less
To many, Theodore Roosevelt was an exemplar of manliness and “muscular Christianity” and an exceptional public servant who led a crusade for social justice. To others, the sage of Oyster Bay was a jingoist, a nativist, a hot-tempered, unpredictable manic, and an egomaniac who put his own interests above America’s good. Roosevelt highly valued biblical morality and considered it vital to personal and public life, including politics. He downplayed doctrine and theological differences and strongly stressed the importance of good works and character.

Examines the use of work camps in the US, the Civilian Conservation Corps (CCC), as a mechanism to address unemployment in the 1930s. Beginning with a brief overview of the origins and establishment of the CCC, King provides an account of these camps at work: the ways in which the Corps was made compatible with traditional US political values as well as how attempts to make it permanent were thwarted. In addition, King underlines the racial dimension of the Corps’ organization and activities, while exploring the implications of the federal government's segregationist arrangements.Less

This chapter discusses the use of niche models to help address the “what” and “where” questions in conservation biology as well as climate change effects. It first reviews the conceptual aspects of the “what” and “where” questions in conservation planning, focusing on topics such as inferences about extinction risk, identification of regions for species reintroductions, conservation reserve network planning, and considerations of how climate change may affect species distributions. Each of these conservation applications is then examined with respect to the conceptual framework laid out for ecological niche modeling. The chapter concludes by offering practical recommendations regarding calibration and evaluation of niche models.Less

Carr's career demonstrated that the naturalist tradition transformed into related disciplines of ecology and conservation over the course of the 20th century. Carr's life exhibits many dimensions of the naturalist tradition. Nearly a decade after Carr died, his example inspired an intense response to an editorial in the journal Conservation Biology. Inspired by the publication of A Naturalist in Florida, editor Reed Noss lamented the demise of natural history and field biology. During the course of his career, Archie Carr embodied E. O. Wilson's goals for the naturalist tradition and conservation biology in his passion for natural history, his acumen for systematics, his sense for ecology, his dedication to conservation, and his ability to write narratives that captured the hearts and minds of scientists and the public in all of these realms. The story of the man who saved sea turtles should be an inspiration to future generations of naturalists and conservationists.Less

Habitat management is commonly used to maintain and enhance the biological interest of many areas of semi-natural habitat, where natural processes no longer create suitable conditions for desired species. Habitat restoration and creation is increasingly being used to increase the extent of ecologically important habitats in order to mitigate the impacts of human development. The modification of past management techniques and the introduction of new ones can provide additional benefits. This book describes the range of techniques used to manage land for biodiversity conservation. The opening sections discuss the general principles of habitat management, including decision-making, mitigating damaging effects of climate change, and monitoring the success of management. These are followed by a series of chapters which describe how to manage specific habitats: grasslands, dwarf-shrub vegetation and shrublands, forests, woodlands and scrub, freshwater wetlands, coastal habitats, arable land, and gardens, backyards, and urban areas. For each of these habitats the book discusses the main factors influencing their value for wildlife, highlights the key decisions that need to be made, and describes and compares the effects of individual management techniques.Less

This chapter presents a model of Rayleigh–Bénard convection. It first describes the fundamental dynamics expected in a fluid that is convectively stable and in one that is convectively unstable, focusing on thermal convection and internal gravity waves. Thermal convection and internal gravity waves are the two basic types of fluid flows within planets and stars that are driven by thermally produced buoyancy forces. The chapter then reviews the equations that govern fluid dynamics based on conservation of mass, momentum, and energy. It also examines the conditions under which the Boussinesq approximation simplifies conservation equations to a form very similar to that of an incompressible fluid. Finally, it discusses the key characteristics of the model of Rayleigh–Bénard convection.Less
