The Ecology of Browsing and Grazing II
Domestic and wild large mammalian herbivores occur on every continent except Antarctica. Through their browsing and grazing, they affect the structure and distribution not only of vegetation, but also of associated fauna. Consequently, the interactions between management practices and herbivore populations influence the biodiversity, structure and dynamics of ecosystems across vast expanses around the globe: signs of human activity that will be detectable for epochs to come. As a follow-up work to The Ecology of Browsing and Grazing, published in 2008, this new volume presents cutting-edge research on the behaviour, distribution, movement, and direct and indirect impacts of domestic and wild herbivores on terrestrial ecosystems. The respective chapters highlight strategic and applied research on cross-cutting issues in palaeontology and ecology, and provide concrete recommendations on the management of large herbivores to integrate production and conservation in terrestrial systems. Given its scope, the book will appeal to students, researchers and anyone interested in understanding these fascinating wild animals and how they shape the natural world.
Neotropical Diversification: Patterns and Processes
This book provides a comprehensive overview of the patterns of biodiversity in various neotropical ecosystems, as well as a discussion on their historical biogeographies and underlying diversification processes. All chapters were written by prominent researchers in the fields of tropical biology, molecular ecology, climatology, paleoecology, and geography, producing an outstanding collection of essays, synthetic analyses, and novel investigations that describe and improve our understanding of the biodiversity of this unique region. With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannahs, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic, which will fascinate both scientists and general readers alike.
American and Australasian Marsupials
This book focuses on the evolution, biogeography, systematics, taxonomy, and ecology of New World and Australasian marsupials, greatly expanding the current knowledge base. There are roughly 140 species of New World marsupials, of which the opossum is the best known. Thanks to recent research, there is now an increasing amount of understanding about their evolution, biogeography, systematics, ecology, and conservation in the Americas, especially in South America. There are also some 270 marsupial species in the Australasian region, many of which have been subject to research only in recent years. Based on this information and the authors’ extensive research, this book provides comprehensive insights into the world's marsupials. It will appeal to academics and specialized researchers, students of zoology, paleontology, evolutionary biology, ecology, physiology and conservation as well as interested non-experts.
Ecologia
Abrangente e aprofundado, Ecologia: de indivíduos a ecossistemas é o livro-texto definitivo sobre as ciências ecológicas. Revisada, atualizada, ampliada e totalmente em cores, esta 5ª edição continua a oferecer, em sua essência, uma exposição da ciência da ecologia. Para isso, trata da distribuição e abundância dos organismos vivos, além das características físicas, químicas e, especialmente, das biológicas, bem como das interações que determinam a ocorrência e a quantidade desses organismos. A obra traz, ainda, tópicos práticos e inúmeros exemplos de como os princípios ecológicos se aplicam ao estudo dos problemas ambientais em diferentes escalas.
Scritti sul Medioevo

Alterità e prossimità di Dio
Tommaso d’Aquino, Bonaventura da Bagnoregio, Sigieri di Brabante, Pietro di Giovanni Olivi e Guglielmo di Ockham sono i cinque protagonisti di questo saggio sulla filosofia medievale. La prima cosa che viene da chiedersi è: perché proprio loro? E poi: che cos’hanno in comune – posto che qualcosa che li accomuni esista – questi cinque pensatori apparentemente così diversi e così distanti l’uno dall’altro, tanto nel tempo quanto nel pensiero? *Ciò che li avvicina è, senza alcun dubbio, l’immane sforzo con cui ciascuno di loro tentò di dare una risposta soddisfacente alla domanda che sta al cuore dell’intera Scolastica: l’uomo con le sole “armi” della ragione, e cio...
Tuco-Tucos
This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.
