Book Description
Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Book Description
This book summarizes the evolution of carnivorous mammals in the Cenozoic of South America. It presents paleontological information on the two main mammalian carnivorous groups in South America; Metatheria and Eutheria. The topics include the origin, systematics, phylogeny, paleoecology and evolution of the Sparassodonta and Carnivora. The book is based on a wide variety of published sources from the last few decades.

Book Description
This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

Book Description
Breathtaking in scope, this is the first survey of the entire ecological history of life on land—from the earliest traces of terrestrial organisms over 400 million years ago to the beginning of human agriculture. By providing myriad insights into the unique ecological information contained in the fossil record, it establishes a new and ambitious basis for the study of evolutionary paleoecology of land ecosystems. A joint undertaking of the Evolution of Terrestrial Ecosystems Consortium at the National Museum of Natural History, Smithsonian Institution, and twenty-six additional researchers, this book begins with four chapters that lay out the theoretical background and methodology of the science of evolutionary paleoecology. Included are a comprehensive review of the taphonomy and paleoenvironmental settings of fossil deposits as well as guidelines for developing ecological characterizations of extinct organisms and the communities in which they lived. The remaining three chapters treat the history of terrestrial ecosystems through geological time, emphasizing how ecological interactions have changed, the rate and tempo of ecosystem change, the role of exogenous "forcing factors" in generating ecological change, and the effect of ecological factors on the evolution of biological diversity. The six principal authors of this volume are all associated with the Evolution of Terrestrial Ecosystems program at the National Museum of Natural History, Smithsonian Institution.

Book Description
"A wealth of field data and ecological information.... Schwartz knows the island and its butterflies better than anyone else alive.... The scholarship is beyond reproach."--Lee D. Miller, curator, Allyn Museum of Entomology, Florida Museum of Natural History The butterflies of the Greater Antilles island of Hispaniola have in general been overlooked since Hall's 1925 summary, a situation Albert Schwartz remedies with this thoroughgoing study. Hispaniola, composed of Haiti and the Dominican Republic, paleogeographically the most interesting of the Antilles, has a topography so ideal for butterflies that nearly two hundred species live there, including sixty endemic species--more than on all the other islands combined. Schwartz's is the first major attempt to uncover the ecological and biogeographic reasons for this diversity. The book contains detailed information on natural history, ecology, taxonomy, elevational distribution, food plants used by adults, and seasonality, as well as occurrence on satellite islands. Schwartz accompanies his species accounts and analyses with photographs of selected ecologies and detailed distribution maps for each species, making this a reference for the general collector to areas that need further research. His descriptive keys, in Spanish and English, list 212 couplets. Besides its obvious value to lepidopterists, this book will fill a need for students on any aspect of West Indian fauna. Albert Schwartz, a professor emeritus of biology at Miami-Dade Community College, is an adjunct curator at the Florida Museum of Natural History and a research associate at the Carnegie Museum of Natural History, the National Museum of Natural History, and the Museo Nacional de Historia Natural in Santo Domingo. He has written and coauthored numerous studies on Caribbean amphibians, reptiles, and Lepidoptera.
