Parasitoid wasps are cosmopolitan, numerous and enormously diverse with probably one million or more species worldwide, most of which occur in the moist tropics. Their ecological importance is enormous although perhaps most evident in their major roles in the control of insect pest populations. In natural ecosystems they are integral in regulating populations of a vast number of insects, and therefore are key players in terrestrial food webs. Knowledge of their biology is still very poor because the current state of taxonomy is still in its infancy in most parts of the world.In this book, we provide an overview of the more than 30 families of parasitoid wasps that occur in the 11 countries i...
Caterpillars are excellent model organisms for understanding how multiple selective forces shape the ecology and evolution of insects, and organisms in general. Recent research using the tools of modern molecular biology, genetics, metabolomics, microbial ecology, experiments conducted at a global level, network analysis, and statistical analyses of global data sets, combined with basic natural history, are yielding exciting new insights into caterpillar adaptations and ecology. The best way to view these research advances is within a framework of tri-trophic interactions. This is a timely topic for research given the central role of caterpillars and plants in the ecology and trophic structu...
A richly illustrated guide to wasps around the world Wasps have been around since before the dinosaurs and are one of the world’s largest insect groups. More than 150,000 species have been identified, and while the black-and-yellow insect with a cinched waist may be the most familiar, most wasps are tiny parasitoids that use other insects for food. Wasps of the World provides a breathtaking look at the diverse characteristics, habitats, and lifestyles of these extraordinary insects. Features more than 250 stunning color photos of numerous species Profiles more than 100 families, with absorbing commentary detailing the range, habits, and notable features of members of each family Every profile includes a distribution map and a table of essential facts about size, diet, reproduction, and habitats Discusses the evolution and biology of wasps, exploring the vital role they play in supporting healthy ecosystems Shows how scientific research is expanding our knowledge about wasps and their behavior
The most up-to-date and authoritative resource on the biology and evolution of solitary bees which draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects.
I en helt vanlig hage kan du finne hundrevis av insektarter. Noen lever der hele livet. Andre trekker som fuglene, og krysser hav og land for å komme på besøk. "Insektene i hagen" handler om det fantastiske mylderet av insekter like utenfor stuedøra. Dette er fortellingen om en spennende oppdagelsesreise rundt huset. Andreas Tjernshaugen ville undersøke hvilke insekter som levde i hans egen hage, og fant mange flere enn ventet. Gjennom fire år har forfatteren oppdaget mer enn fem hundre arter, og fortsatt dukker det opp nye. Insektene er nesten ufattelig mangfoldige. Mer enn halvparten av alle kjente arter er insekter, og hagen er et fint sted å bli kjent med humlene, sommerfuglene og alle de andre. Boka er en oppfordring til å gå ut og se selv, og en veiviser for alle som er nysgjerrige på hva som kravler, svirrer og flyr i hagen.
A multidisciplinary perspective on the dynamic processes occurring in Earth's mantle The convective motion of material in Earth's mantle, powered by heat from the deep interior of our planet, drives plate tectonics at the surface, generating earthquakes and volcanic activity. It shapes our familiar surface landscapes, and also stabilizes the oceans and atmosphere on geologic timescales. Mantle Convection and Surface Expressions brings together perspectives from observational geophysics, numerical modelling, geochemistry, and mineral physics to build a holistic picture of the deep Earth. It explores the dynamic processes occurring in the mantle as well as the associated heat and material cycl...
