Available in PDF, EPUB and Kindle. Book excerpt: A richly illustrated, captivating study of army ants, nature’s preeminent social hunters. A swarm raid is one of nature’s great spectacles. In tropical rainforests around the world, army ants march in groups by the thousands to overwhelm large solitary invertebrates, along with nests of termites, wasps, and other ants. They kill and dismember their prey and carry it back to their nest, where their hungry brood devours it. They are the ultimate social hunters, demonstrating the most fascinating collective behavior. In Army Ants we see how these insects play a crucial role in promoting and sustaining the biodiversity of tropical ecosystems. The ants help keep prey communities in check while also providing nutrition for other animals. Many species depend on army ants for survival, including a multitude of social parasites, swarm-following birds, and flies. And while their hunting behavior, and the rules that govern it, are clearly impressive, army ants display collective behavior in other ways that are no less dazzling. They build living nests, called bivouacs, using their bodies to protect the queen and larvae. The ants can even construct bridges over open space or obstacles by linking to one another using their feet. These incredible feats happen without central coordination. They are the result of local interactions—self-organization that benefits the society at large. Through observations, stories, and stunning images, Daniel Kronauer brings these fascinating creatures to life. Army ants may be small, but their collective intelligence and impact on their environment are anything but.
Book Synopsis Processes Shaping the Community Composition of Birds Following Army Ant Swarms by : Laura Gomez-Murillo

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the influence of species interactions on community structure is a long-standing goal in ecology. Shifts in species interactions, however, can occur over time and space in response to environmental variation, changes in resources, alteration of habitat, and other factors. Here I investigated the mechanisms influencing the species interaction in one type of mixed-species group – army ant-following birds. First, I used a social network analysis approach to examine how the structure of the communities of army ant-following birds varied along a rainfall and fragmentation gradient in Panama. I found that network structures varied significantly across the rainfall gradient, with networks differing in size, complexity, and cohesion across the gradient. Whereas, fragmentation resulted in the dissolution of these groups. Second, I examined how characteristics of the ant swarms and abundance of key, dominant species influenced the overall bird community attending swarms. I found that individuals use multiple cues to make decisions about whether to forage in groups, and both the species present and swarm traits alter the costs and benefits of foraging in mixed-species groups. As the environment continues to change, mismatches between cues and profitability, shifts in the species present, and shifts in costs and benefits may arise, dramatically altering the structure of these groups. Understanding the relationships between environmental factors and species interactions contributes to our ability to predict the potential negative impact of climate change and habitat alteration on the dynamics of species interactions and subsequently in the community structure per se.

Book Synopsis Army Ants and Obligaate Ant-following Birds by : Susan K. Willson
Download or read book Army Ants and Obligaate Ant-following Birds written by Susan K. Willson and published by . This book was released on 2003 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five species of obligate ant-following birds (Phlegopsis nigromaculata, Myrmeciza fortis, Rhegmatorhina melanosticta, Gymnopithys salvini, Thamnophilidae; Dendrocincla merula, Dendrocolaptidae) and two species of army ants (Eciton burchelli and Labidus praedator) were studied in Amazonian Peru over five years. The question of species coexistence in these five ecologically similar bird species was explored through analysis of population ecology, behavior and spatial movement patterns of the birds. Two of the five bird species (D. merula and M. fortis) utilized one or the other of the two army ant species as a preferred foraging resource. The three obligate ant-following antbirds that did not prefer one army ant species over the other (P. nigromaculata, R. melanosticta, and G. salvini) are segregated by body mass, which may allow differential utilization of space along an antswarm front's width. This would permit a smaller, more subordinate species to "fit" along the front of an antswarm that was already "full" to a different bird species. Behaviorally, species implemented different strategies when choosing where to forage among available E. burchelli antswarms. Nest site selection contributed to niche breadth among the obligate ant-followers, and may act to constrain populations of the dominant species P. nigromaculata from expanding to utilize more of the available army ant resource. Constraints on the dominant species may provide the socially subordinate R. melanosticta and G. salvini with the niche space they need to coexist with P. nigromaculata . Population dynamics of the birds were not stable over five years of data collection, and the total population of obligate ant-followers dropped by almost half over the course of the study. I suggest that periodic population declines are a normal occurrence in obligate ant-following guilds. Population fluctuations decreased interference competition among individuals and may increase the ability of the subordinate species R. melanosticta to coexist with the larger, dominant P. nigromaculata at Cocha Cashu. Home range size of each antbird species was minimized in some years through reliance on the unpredictable but abundant foraging opportunities at L. praedator antswarms. This poorly studied ant species played a pivotal role in expanding the available foraging resource for obligate ant-following birds, which allowed an increase in population densities well above what would be supported solely by E. burchelli army ants. The army ant E. burchelli has been well studied on a micro-habitat scale, but measures of behavioral ecology and population density are largely unknown for the Amazon basin and are estimated for the first time in this study. Nests and reproductive biology of four of the five bird species were undescribed at the start of this study, and nests, eggs and nestlings are described for P. nigromaculata, R. melanosticta and G. salvini . The dissertation concludes with a comparative examination of obligate ant-following guilds at three additional Neotropical sites.

Book Synopsis Adventures among Ants by : Mark W. Moffett
Download or read book Adventures among Ants written by Mark W. Moffett and published by Univ of California Press. This book was released on 2010-05-05 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intrepid international explorer, biologist, and photographer Mark W. Moffett, "the Indiana Jones of entomology," takes us around the globe on a strange and colorful journey in search of the hidden world of ants. In tales from Nigeria, Indonesia, the Amazon, Australia, California, and elsewhere, Moffett recounts his entomological exploits and provides fascinating details on how ants live and how they dominate their ecosystems through strikingly human behaviors, yet at a different scale and a faster tempo. Moffett’s spectacular close-up photographs shrink us down to size, so that we can observe ants in familiar roles; warriors, builders, big-game hunters, and slave owners. We find them creating marketplaces and assembly lines and dealing with issues we think of as uniquely human—including hygiene, recycling, and warfare. Adventures among Ants introduces some of the world’s most awe-inspiring species and offers a startling new perspective on the limits of our own perception. • Ants are world-class road builders, handling traffic problems on thoroughfares that dwarf our highway systems in their complexity • Ants with the largest societies often deploy complicated military tactics • Some ants have evolved from hunter-gatherers into farmers, domesticating other insects and growing crops for food

This book was released on 2022-03-29 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Beautifully illustrated with color photographs, the book offers a view into parallels between seemingly out-of-this-world ant societies and our own, including cities, an intense work ethic, division of labor, intragroup cooperation combined with genocidal outgroup warfare, even a kind of to-the-death national loyalty. The authors’ scientific rigor is matched by their joy in their subjects.”—The Wall Street Journal Shortlisted for the 2022 Helen and Kurt Wolff Translator’s Prize This sweeping portrait of the world’s uncontested six-legged conquerors will open your eyes to the secret societies thriving right beneath your feet—and shift your perspective on humanity. The closer you get to ants, the more human they look. Ants build megacities, tend gardens, wage wars, and farm livestock. Ants have flourished since the age of the dinosaurs. There are one million ants for every one of us. Engineered by nature to fulfill their particular roles, ants flawlessly perform a complex symphony of tasks to sustain their colony—seemingly without a conductor—from fearsome army ants, who stage twelve-hour hunting raids where they devour thousands, to gentle leafcutters cooperatively gardening in their peaceful underground kingdoms. Acclaimed biologist Susanne Foitzik has traveled the globe to study these master architects of Earth. Joined by journalist Olaf Fritsche, Foitzik invites readers deep into her world in both the field and the lab. Exploring these insects’ tiny yet incredible lives will inspire new respect for ants as a global superpower. Publisher’s note: Planet of the Ants was previously published in hardcover as Empire of Ants.
Book Synopsis The Evolution of Social Behaviour by : Michael Taborsky
Download or read book The Evolution of Social Behaviour written by Michael Taborsky and published by Cambridge University Press. This book was released on 2021-08-26 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.
Book Synopsis Bird Nests and Construction Behaviour by : Mike Hansell
Download or read book Bird Nests and Construction Behaviour written by Mike Hansell and published by Cambridge University Press. This book was released on 2000-08-31 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bird Nests and Construction Behaviour provides a broad view of our understanding of the biology of the nests, bowers and tools made by birds. It illustrates how, among vertebrates, the building abilities of birds are more impressive and consistent than for any other builders other than ourselves, yet birds seem to require no special equipment, and use quite uncomplicated behaviour. In doing so, the book raises general issues in the field of behavioural ecology including the costs of reproduction, sexual selection and the organisation and complexity of behaviour. Written for students and researchers of animal behaviour, behavioural ecology and ornithology, it will nevertheless make fascinating reading for architects and engineers interested in understanding how structures are created by animals.

Book Synopsis The Atlantic Forest by : Marcia C. M. Marques
Download or read book The Atlantic Forest written by Marcia C. M. Marques and published by Springer Nature. This book was released on 2021-01-13 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Forest is one of the 36 hotspots for biodiversity conservation worldwide. It is a unique, large biome (more than 3000 km in latitude; 2500 in longitude), marked by high biodiversity, high degree of endemic species and, at the same time, extremely threatened. Approximately 70% of the Brazilian population lives in the area of this biome, which makes the conflict between biodiversity conservation and the sustainability of the human population a relevant issue. This book aims to cover: 1) the historical characterization and geographic variation of the biome; 2) the distribution of the diversity of some relevant taxa; 3) the main threats to biodiversity, and 4) possible opportunities to ensure the biodiversity conservation, and the economic and social sustainability. Also, it is hoped that this book can be useful for those involved in the development of public policies aimed at the conservation of this important global biome.
