Book Description
Tropical forests, including the biodiverse Brazilian Atlantic Forest, are crucial for global climate regulation and biodiversity conservation. Conservation efforts seek to regenerate these forests, although herbivory can pose a threat to these secondary succession forests. Previous work suggests that plant diversity can influence herbivore communities, which can influence plant condition and performance. This paper explores the impact of plant neighborhood diversity on herbivory rates and arthropod communities in experimental early-successional tropical forests in Sao Paulo, Brazil. Pioneer plant community assembly experiments conducted in deforested areas adjacent to fragments of Brazilian Atlantic Forests reveal that higher plant neighborhood diversity correlates with lower herbivory rates and greater arthropod species richness, although plant diversity had no impact on arthropod abundance. This research contributes to a deeper understanding of how biotic interactions between plants, herbivores, and arthropod assemblages are shaped by plant neighborhood diversity, and therefore of community assembly processes.

Book Description
Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems

Book Description
Lianas are woody vines that were the focus of intense study by early ecologists, such as Darwin, who devoted an entire book to the natural history of climbing plants. Over the past quarter century, there has been a resurgence in the study of lianas, and liana are again recognized as important components of many forests, particularly in the tropics. The increasing amount of research on lianas has resulted in a fundamentally deeper understanding of liana ecology, evolution, and life-history, as well as the myriad roles lianas play in forest dynamics and functioning. This book provides insight into the ecology and evolution of lianas, their anatomy, physiology, and natural history, their global abundance and distribution, and their wide-ranging effects on the myriad organisms that inhabit tropical and temperate forests.

Book Description
Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.

Book Description
Variable Plants and Herbivores in Natural and Managed Systems examines individual, population, species, and community responses of herbivores to plant variation, with emphasis on insects, fungi, bacteria, and viruses. It is divided into five parts encompassing 18 chapters that discuss variability as a mechanism of defense used by plants against their parasites and the effects of variability on herbivores at several different levels of complexity. After a brief discussion on plant-herbivore interactions, the first part of this book considers sources of within-plant variation and effects on the distribution and abundance of herbivores. Part II examines interplant variation, the co-evolutionary problems it poses for herbivores, and the ecological and evolutionary responses of these animals. It discusses the effects of host-plant variability on the fitness of sedentary herbivorous insects. Part III discusses the role of host variability in the evolution of feeding specialization, genetic differentiation, and race formation. The importance of host variation to the organization of herbivore communities and the manipulation of host-plant variability for the management of herbivore pest populations are presented in the remaining parts. This book will be helpful to agriculturists, silviculturists, biologists, and researchers who wish to expand their knowledge in dynamics of plant-herbivore relationships.

Book Description
Insect Ecology: An Ecosystem Approach, Fifth Edition provides the most updated and comprehensive knowledge of the diversity of insect responses to environmental changes and their effects on ecosystem properties and services. Written by an expert in the field, this book addresses ways in which insect morphology, physiology and behavior tailor their adaptation to particular environmental conditions, how those adaptations affect their responses to environmental changes, and how their responses affect ecosystem properties and the ecosystem services on which humans depend for survival. This edition also addresses recent reports of global declines in insect abundance and how these declines could affect human interests. Insect Ecology: An Ecosystem Approach, Fifth Edition is an important resource for researchers, entomologists, ecologists, pest managers and conservationists who want to understand insect ecology and to manage insects in ways that sustain the delivery of ecosystem services. Graduate and advanced undergraduate students may also find this as a useful resource for entomology and specifically insect ecology courses. - The only insect ecology text that emphasizes insect effects on ecosystem properties and services, as well as evolutionary adaptations to environmental conditions - Includes new material on long-term trends in insect abundance, addressing the so-called "insect apocalypse - Offers crucial updates on mechanisms by which insects affect, and potentially regulate, ecosystem structure and function - Applies ecological principles to improved management of insects for the sustainable delivery of ecosystem services

Book Description
This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? How can our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.
