  • The theory and practice of molecular ecology draw on a number of subjects, particularly genetics, ecology and evolutionary biology. Although the foundations of molecular ecology are not particularly new, it did not emerge until the 1980s as the discipline that we now recognize. Since that time the growth of molecular ecology has been explosive, in part because molecular data are becoming increasingly accessible and also because it is, by its very nature, a collaborative discipline.

  • This is because IT uses primers based on allele sequences of functionally characterized genes, and thus specific banding patterns corresponding to plant phenotypes can be identified (Cernák, 2008; Cernák et al., 2008; Gizaw, 2011). However, development of such markers depends on the availability of robust genomic databases holding several target sequences for IT marker development. Functional gene characterization criteria might be limiting factors, since it is not possible to establish gene functions in a molecular ecological sense for all genes.

  • When I was asked by Timber Press to write a new book on resins, including amber—Howes’s 1949 Vegetable Gums and Resins was the most recent such effort—the breadth of interdisciplinary coverage seemed too ambitious for an individual person. There have been so many advances in resin research in the past half century, including the development of new fields of research such as chemical ecology, and the exploration of other interesting facets about resins made possible by new chemical, molecular, and microscopic techniques.

  • T his second edition provides an updated and expanded synthesis of feedbacks and interactions between insects and their environment. A number of recent studies have advanced understanding of feedbacks or provided useful examples of principles. Molecular methods have provided new tools for addressing dispersal and interactions among organisms and have clarified mechanisms of feedback between insect effects.

  • Multidisciplinary landscape assessment, or MLA, is a set of methods developed by CIFOR scientists to determine ‘what is important to local communities, in terms of landscape, environmental services, and resources’. The approach is rooted in social (anthropology, ethnobotany and socio-economics) as well as natural sciences (botany, ecology, geography and pedology); was tested and used in different countries (Bolivia, Cameroon, Gabon, Indonesia, Mozambique and Philippines). The methods are fully detailed in four languages: English, French, Indonesia and Spanish (Sheil et al.

  • This should be a puzzle. Much of the rationale for development economics as a specialization is the thought that poor countries suffer particularly frominstitutional failures.But institutional failures in greatmeasuremanifest themselves as externalities. To ignore population growth and ecological constraints in the study of poor countries would be to suppose that demographic decisions and resource-use there give rise to no externalities of significance, and that externalities arising from institutional failure have a negligible effect on resource-use and demographic behaviour.
