Indexes journal articles in ecology and environmental science. Nearly 700 journals are indexed in full or in part, and the database indexes literature published from 1982 to the present. Coverage includes habitats, food chains, erosion, land reclamation, resource and ecosystems management, modeling, climate, water resources, soil, and pollution.

In The Geometrid Moths of Europe volume 2 on Sterrhinae, a number of difficult genera such as Cyclophora, Scopula and Idaea are covered. Especially Idaea with more than 100 species occuring in Europe, has caused a lot of problems to identify, but based on the many specimens illustrated on the 24 colour plates, the species of this genus can be identified much easier now. Apart from its largest species, the genus Idaea is illustrated in 1.5 times natural size. The remaining Sterrhinae are in natural size on the colour plates. On additional black and white photos for species which are difficult to identify, their differential characters are pointed out with arrows. Three new species and three new subspecies are described. A map with the European distribution is given, and with dots for verified specimens. Finally there are line drawings of male and female genitalia of all species and also this volume contains a systematic catalogue of the European species and including those of the neighbouring regions such as North Africa, Macaronesia, Turkey, and the Middle East. Originally published with imprint Apollo (ISBN 9788788757378) in 2004.

A comprehensive english-language reference work on morphology, physiology and development of the moths and butterflies of the world. Written by a truly international team of specialists, the overall level of expertise of the book is unsurpassed, and several chapters present substantial amounts of original information. The book is richly illustrated, and all chapters have extensive bibliographies. Volume I has been published in 1998 and covers the evolution, systematics and biogeography of Lepidoptera. The goal of both volumes is to provide an overview of the current state of knowledge of this outstandingly important insect group.

Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.
