Theory and early empirical work posed that herbivore pressure should be lower on islands than on the mainland owing to lower herbivore abundance and diversity in insular systems. Consequently, plant taxa found on islands are expected to be less protected or even to have lost their defences completely. While early observational studies supported the prediction of lower herbivory and plant defences on islands, recent island-mainland comparisons have yielded mixed results, with some studies finding no differences between islands and mainlands or, surprisingly, higher herbivory and plant defences on islands. In this book, the authors aim to re-assess current theory and initiate a new generation of work on insularity effects on plant-herbivore interactions. This book aims to fill the research gaps by integrating the research that has been done to date and by compiling and summarising new research on insularity effects on plant-herbivore interactions. It provides a critical examinationof the patterns in light of classical theory and identifies potential mechanisms or underlying processes. It also aims to raise new questions that will form the basis for a revised and more robust research programme.

Sustainable development is a process to improve the quality of life of people, while maintaining the ability of social–ecological systems to continue to provide valuable ecological services that social systems require. In the Galapagos Islands, the maintenance of amenity resources to support tourism and the quality of life of residents is explicitly linked to ecosystem goods and services, particularly, the accessibility to high-quality natural environments and the terrestrial and marine visitation sites that showcase iconic species.On June 26-30, 2022, the Galapagos Science Center celebrated its 10-Year Anniversary. As the crowning event of the anniversary celebration, the World Summit on Island Sustainability was held on San Cristobal Island, Galapagos Archipelago of Ecuador. The intent of the World Summit was to bring together leading experts on island ecosystems and, particularly, on island sustainability from across the globe to represent a diversity of perspectives, approaches, and stakeholder groups. The World Summit was an exclusive event that featured an “expert convening” of scholars and practitioners to address the social, terrestrial, and marine sub-systems of the Galapagos Islands and other similarly challenged island ecosystems from around the globe. The World Summit attracted 150 scientists to the Galapagos Islands to discuss projects conducted, for instance, in the Galapagos Islands, Hawaii, Guam, French Polynesia, Chile, Australia, and the Caribbean Islands. Island vulnerability, resilience, and sustainability were examined by scholars, for instance, from the University of North Carolina at Chapel Hill, Universidad San Francisco de Quito, Catholic University of Chile, University of Guam, James Cook University, University of the Sunshine Coast, North Carolina State University, North Carolina Museum of Natural Sciences, California Academy of Sciences, University of San Francisco, and the University of South Alabama aswell as affiliated scientists from Exeter University, University of Edinburgh, University of Southampton, and the Galapagos National Park. The World Summit also included scholars from Re:wild, World Wildlife Fund, EarthEcho, and the East-West Center, Hawaii.

This book presents chapters, written by leading coastal scientists, which collectively depict the current understanding of the processes that shape barrier islands and barrier spits, with an emphasis on the response of these landforms to changing conditions. A majority of the world's population lives along the coast at the dynamic intersection between terrestrial and marine ecosystems and landscapes. As narrow, low-lying landforms, barriers are especially vulnerable to changes in sea level, storminess, the geographic distribution of grass species, and the rate of sand supply—some barriers will undergo rapid changes in state (e.g., from landward migrating to disintegrating), on human time scales. Attempts by humans to prevent change can hasten the loss of these landforms, threatening their continued existence as well as the recreational, financial and ecosystem service benefits they provide. Understanding the processes and interactions that drive landscape response to climate change andhuman actions is essential to adaptation. As managers and governments struggle to plan for the future along low-lying coasts worldwide, and scientists conduct research that provides useful guidance, this volume offers a much-needed compilation for these groups, as well as a window into the science of barrier dynamics for anyone who is generally interested in the impacts of a changing world on coastal environments.

This book is dedicated to the study of the islands and their role in a globalised world. Beside Coastal or Oceanic/Marine Geography, there is little comprehensive material about the speciality of small island geography so far. This volume aims to bridge natural, social and cultural science perspectives. In Geography of Small Islands readers learn about the physical development of islands, their cultural and political importance, as well as their economic particularities. This book appeals to researchers, students and scholars with an interest in the special characteristics in spatialities of islands.

A series of original papers and reviews dealing with the peculiarities of island insects and their conservation in many parts of the world. Contributions to this special issue of Journal of Insect Conservation range from biogeographical analyses and ecological features of island insects and their evolution to the variety of concerns for their wellbeing, and practical conservation through a variety of, sometimes novel, approaches. They provide a valuable and up-to-date resource for entomologists and conservation practitioners.

Biogeography considers the distribution of biological units over a wide range of scales. The units range from genotypes, populations and species to families and higher taxa. Processes can be local, such as the isolation on islands due to sea-level fluctuations, or large-scale tectonic processes that separates continents and creates oceans. In all processes time is an important factor and by combining data on recent patterns with paleontological data the understanding of the distribution of extant taxa can be improved. This volume focuses on speciation due to isolation in island-like settings, and the evolution of large-scale diversity as the result of origination, maintenance and extinction.
