Abstract
Summary Both the public and the scientific perception of an island's value are important in deciding its future, with regard to the levels of access, protection and funding for research. There is a popular belief that the preservation of islands equates to the slightly idiosyncratic conservation of unique remote habitats, where the value of any island is its isolation. However, by understanding how scientists use islands, a different picture emerges; islands may be seen also as integrated, or representative fragments of the world that contribute to biodiversity and scientific theory far beyond their narrow geographical boundaries. Here, we broadly review the full scope of values science places on islands. We resolve four central perspectives by which scientists view islands, based on how islands are incorporated into their research: (i) species-level studies; (ii) island-level studies; (iii) islands as model systems; and (iv) islands as part of a global network. Recognising this diverse value system helps enlarge our understanding of islands and reforges their importance to the public and policy makers. [PUBLICATION ABSTRACT]
