Book Synopsis Chalcidoidea of Iran by : Hassan Ghahari
Download or read book Chalcidoidea of Iran written by Hassan Ghahari and published by CABI. This book was released on 2021-01-27 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.

Book Synopsis Global Guide of the Flat Wasps (Hymenoptera, Bethylidae) by : Celso O. Azevedo
Download or read book Global Guide of the Flat Wasps (Hymenoptera, Bethylidae) written by Celso O. Azevedo and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The flat wasp family Bethylidae Haliday lacks global scale literature on their alpha taxonomy. The only world revision for the family was by Kieffer in 1914 and is fully out of date and somewhat useless; the only catalog for the family was made by Gordh & Móczár in 1990 and does not include hundreds of changes made since then; and the most recent world genera keys were proposed by Terayama in 2003, but do not reflect the current knowledge we have for the family. Given this scenario, we present a global guide of Bethylidae with diagnoses, taxonomic evaluation, keys, and a checklist of all their extant genera and subfamilies. Key words: Chrysidoidea, systematics, taxonomy, synopsis, synonymies, homonymies."--Page 5.
Book Synopsis Species Conservation in Managed Habitats by : Werner Kunz
Download or read book Species Conservation in Managed Habitats written by Werner Kunz and published by John Wiley & Sons. This book was released on 2016-04-28 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an author with longstanding experience in the ecology of insects and birds and with a stellar academic record in molecular life sciences, this is a welcome challenge to the widely held beliefs in conventional environmental policies. Werner Kunz convincingly explains why maintaining high biodiversity in Europe depends heavily on the existence of open space and sparse ground vegetation that is neither used for intensive modern agriculture, nor eliminated by reforestation. He questions the commonly propagated opinion that nature conservation is equivalent to species protection - and shows that technical habitat design can rescue endangered species. A must-have for environmental agencies, policy makers, ecologists and all who are witnessing the current loss of species in Central Europe.
Book Synopsis A revision of the Chinese Stephanidae (Hymenoptera, Stephanoidea) by : Chun-dan Hong
Download or read book A revision of the Chinese Stephanidae (Hymenoptera, Stephanoidea) written by Chun-dan Hong and published by PenSoft Publishers LTD. This book was released on 2011-06-21 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stephanidae Leach, 1815 (Hymenoptera: Stephanoidea) is an imperfectly known family in its systematics and many types have never been studied since their descriptions. At present 345 extant species are recorded worldwide, and only twenty species in five genera are known from six provinces of China. An extensive review of previously published literatures and previously unidentified specimens referred to Stephanidae results in taxonomic revision of the family from China. This monograph includes identification of six new species, establishment of nine new synonyms and designation of one lectotype. Descriptions and illustrations of all Chinese species are provided and keys to five genera from China and their species are made. The results of this monograph clarify some taxonomic confusion, richen the geographical distributions of Stephanidae in China and provide facilities for further research in Chinese Stephanidae.
Book Synopsis Relict Species by : Jan Christian Habel
Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
