Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival.

Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth s biodiversity. Among arthropods, insects are predominant, with ca. 1 million...

This book is the second in a series designed to facilitate identification of South American insects likely to be encountered in, on, or near water and wetlands. After a general introduction to the study of Ephemeroptera, the mayflies, it provides illustrated keys for the identification of all species in South America that were described by the beginning of 2002. It is the only up-to-date comprehensive work of its kind encompassing the entire South American continent. The many illustrations facilitate identification of a mayfly specimen to species with reasonable certainty if the life stage...

The first soil survey in the Philippines was done by Mr. Clarence Dorsey, an American soil scientist in the province of Batangas in 1903. The Soils of the Philippines, however, is the first comprehensive summary of more than a century of soil-survey work in this country. It integrates the soil concepts of the reconnaissance soil-survey results, which commenced as early as 1934 and continued until the mid 1960s, with the semi-detailed soil surveys that continue to this day.The result is the first-ever genetic key for classifying Philippine soils at soil series level; thus,...

Dieser Atlas bietet einen exemplarischen Einblick in das bizarre Reich der bodenbewohnenden Arthropoden. In der vergleichenden Darstellung von brillanten rasterelektronenmikroskopischen Abbildungen mit auergewohnlich lebensnahen Zeichnungen wird offenbar, dass hinter der Formenmannigfaltigkeit dieser Tiere physiologische Mechanismen fur okologische Anpassungen an das differenzierte Leben im Boden stehen. Die Bedeutung der Arthropoden als Konsumenten am Abbau des pflanzlichen Bestandsabfalls und am Stoffkreislauf im Boden wird besonders hervorgehoben.

Dieses Buch entstand aus der...
