This book presents some conditions and/or factors which are little known as possibly affecting moth population density, or have been little-studied and, determines their possible usefulness for integrated pest control in vineyards.

This atlas is an explanatory overview of Kenya's 1065 species, useful both to the birdwatcher as a means of finding birds and interpreting the significance of field observations, and to the ornithologist as a standard reference work.

This book discusses methods which might appropriately be employed under various circumstances. It is concerned with control of insect pests and tse-tse flies, and considers prospects for integrated control of the African trypanosomiases, in which vector control is envisaged as playing a key role.

This book demonstrates the common problems faced by fruit growers throughout the Community and shows the importance of weeds in fruit crops. It summarizes a list of the worst weeds in vine and soft fruits in each European Country.

This text is a reference work for botanists studying the flora of South Asia. As commander of Malabar, van Reed was responsible for compiling the Hortus Malabaricus, a major publication of the flora and medical use of plants.

This book is an outcome of the proceedings of the expert's meeting on the protection of citrus groves held in Acireale in 1985. It focuses on the methods and strategies of integrated control taking into account the influence of some phytochemicals on the physiology of the citrus crop.

This book is a compilation of proceedings that contain abstracts of all papers/posters presented at the International Echinoderm Conference held in 1984 and complete papers from those submitted for publication and accepted on the recommendations of referees.

This work covers the geographical distribution of Crustaceans with hypotheses on how the distribution took place, based on fossil and recent records.

Seventh volume (in no planned sequence) of the revision of the works of Trimen, Alston, Abeywickrama. A worthy successor to a great and extremely scarce work. We lament that this revision is printed on acidic paper. Annotation copyright Book News, Inc. Portland, Or.

This part completes the review of the largest and economically richest order of fishes, Perciformes, begun in Part 3. It includes 12 suborders with keys and brief descriptions to 230 species, and information on their ecology and distribution.

Prepared at the Royal Botanic Gardens, Kew, in collaboration with the East African Herbarium, the flora is designed to a high academic standard to produce reference for anyone concerned with the identification and utilization of plants in East Africa.

This book is a comprehensive review of the genera of Verbenaceae, a flowering plant family, found in tropical East Africa. It presents information on their character, occurrence, habitat, phenotypic variations and distribution of each of the species under these genera.

This volume focuses on the Boranginaceae family. They are annual or perennial herbs, often woody at the base, subshrubs, trees or woody climbers, usually characteristically scabrid or hispid and occur in both temperate regions and tropics of old and new worlds with 2000 species.

This work consists of seven plenary lectures read at an international conference in Tampa, USA.

A listing and analysis of 3106 references to the rhinoceros in books and articles.

This book deals with the practical aspects in regeneration of field crop plants; regeneration of pasture plants; and regeneration of horticultural plants. It discusses the methods to increase seed stocks of cross-pollinated species.

This book discusses the constraints on biological control ranging from the difficulty of convincing growers that they should infest their crops artificially to the effect of cultural techniques.

This book is an outcome of the second European conference on Echinoderm brussels held in Belgium in 1989. It covers the following areas of research in echinoderm: paleontology, reproduction, development and larval biology, evolution, systematics and biogeography, morphology and physiology.

This book is an outcome of the European colloquium on Echinoderms held at Brussels in 1979. It is divided into three major sections: paleontology, skeletal structures, and systematics and zoogeography. The book is useful for zoologists, scientists in zoology, and academics.

This work presents improved equations for monthly water resources models, in particular for interception and transpiration.

This text discusses all the wild and as well as major introduced species growing in the European part of Russia and bordering regions. A complete and sequential typification of all taxonomic categories is a feature of the volume.

This work contains the description of the subfamily Cichorioideae of the large family of the composites (Asteraceae), which includes 33 genera and 945 species. Both wild and important introduced plants of this subfamily, found in the European part of Russia and bordering regions, are described, with

From the third international workshop on the subject (U. of Florence, 1997), come 18 papers reviewing the issue of alien crayfish decimating the relatively few native species in European freshwater environments. In a historical and taxonomic context, the initial paper explains why such homogenizatio

As fish farming moves into its "industrial phase", technology will be an important factor in determining its successful development. This volume presents proceedings of a conference considering juvenile marine fish, open production plants and closed production plants.

Topics covered in this volume include: transformation morphology on structures in the head of cichlid fishes; the structure and function of fish liver; atretic follicles and corpora lutea in the ovaries of fishes; effects of gill dimension on respiration; and the efects of pesticides on fish.

This text analyzes the structure of fish populations in inland reservoirs, based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes and seven from large reservoirs in plains.

This text contains the papers of a meeting on American isopods, the only crustacean group with representatives in all terrestrial ecosystems. It deals with two main subjects: the effects of stressful conditions on the individual animal; and distribution and selection of microhabitat.

A selection of papers, reports and posters presented at the third European conference on echinoderms - a thorny-skinned group of marine animals considered of great zoological interest. The contributions look at morphology, development biology, ecology and symbiosis.

The proceedings of the Seventh International Echinoderm Conference, held at Atami, Japan, September 1990. In addition to sections covering ecology, evolution, reproduction, morphology, molecular biology, developmental biology, physiology, behavior, and paleontology, there are four plenary lectures a

This book addresses earth observation data policy.
