Description : Hawkmoths are large charismatic insects with highly variable and colourful larvae. Some species are specialised in their habitat preferences, but others are widespread and often encountered in gardens. However, little is known about most species, and associating the adults with their larvae has previously been difficult or impossible. Hawkmoths of Australia allows identification of all of the Australian hawkmoths for the first time and treats species found on mainland Australia, Tasmania and all offshore islands within Australian limits. It presents previously undescribed life histories of nearly all species and provides a comprehensive account of hawkmoth biology, including new parasitoids and their hawkmoth hosts. Detailed drawings and photographs show the external and internal morphology of adults and immatures, and eggs, larval instars and pupa. Keys are provided for last instar larvae and pupae of the 71 species that the authors have reared. The book is concluded by a glossary, appendices to parasitoids and larval foodplants, an extensive reference list with bibliographical notes and a comprehensive index. The wealth of new information in this book makes it an essential reference for anyone interested in these moths. Hawkmoths of Australia is Volume 13 of the Monographs on Australian Lepidoptera Series.

Description : The term 'dispersal centre' literally refers to the place from which a dispersal process started. However, it also implies the location of a centre of diversity, frequently even a recent one, as well as the location of a preservation centre or refuge during regressive phases in less remoted periods of earth's history, and that of a possible speciation centre. The latter may have been the place of differentia tion of subspecies, or species, provided that the isolation period has been suffi ciently long. The term deliberately brings the dynamics to prominence which is inherent in the process of dispersal. This dynamics is neither properly recognized when considering ranges 'whose recent structures more or less force us to consider them ,as static entities' (DE LATTIN 1967, p. 16)*, nor adequately taken into account by systematic typology. Yet, it is, in fact, the change that takes place in a range, which is of great significance in evolutionary genetics. In the case of range regressions which may lead to a diminution or rupture of the range pattern according to the pressure of the endogenous or exogenous triggering factors, subsequently arising distribution obstacles may result in a geographical isolation of partial populations or popula tion parts. Their sufficiently long spatial and reproductive isolation and the allele loss resulting from the change of the population size promote a divergent develop ment.

Description : More than twenty years ago, the Food and Agriculture Organization of the United Nations contributed to the growing recognition of the role of pollination in agricultural production, with the publication of “The Pollination of Cultivated Plants in the Tropics”. Since that time, the appreciation of pollinators has grown, alongside the realization that we stand to lose them. But our knowledge and understanding of crop pollination, pollinator biology, and best management practices has also expanded over this time. This volume is the first of two “compendiums for practitioners”, sharing expert knowledge on all dimensions of crop pollination in both temperate and tropical zones. The focus in this first volume is on applied crop and system-specific pollination.

Description : This volume is a synthesis of existing knowledge about the flora and fauna of Costa Rica. The major portion of the book consists of detailed accounts of agricultural species, vegetation, amphibians, reptiles, mammals, birds, and insects. "This is an extraordinary, virtually unique work. . . . The tremendous amount of original, previously unpublished, firsthand information is remarkable."—Peter H. Raven, Director, Missouri Botanical Garden "An essential resource for anyone interested in tropical biology. . . . It can be used both as an encyclopedia—a source of facts on specific organisms—and as a source of ideas and generalizations about tropical ecology."—Alan P. Smith, Ecology
