This book was released on 2013-09 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1919 edition. Excerpt: ... tree of the suborder, and should bear the name of the man who has done more than any other worker to further our knowledge of the Odonata, namely Baron de Selys-Longchamps. In contrast to the Coenagrioninae the Protoneurinae do not have the reduction in the number of postnodals, they are as numerous in Selysioneura (fig. 153) as in Disparoneura (fig. 132). Ill--tendencies in specialization These have been rather fully discussed in previous papers, particularly by Dr. Needham (1903a) for the order Odonata as a whole, and by Dr. Calvert (1913) for the Zygoptera with special reference to the Megapodagrioninae. It is my purpose here to review their opinions and to add a few observations of my own. I think it must be apparent from the preceding discussion on the phylogeny that the outstanding features in the development of the Zygoptera are a constant reduction and simplification of venation. At any rate this is true from the standpoint of comparative morphology and to a certain degree it seems to be so paleontologically. As might be expected this reduction is to some extent accompanied by a decrease in the power of flight. Dr. Calvert says, "Many of the ideas which have been expressed on the changes which have taken place in the venation of the Odonate wings have been based on the comparative morphology of living representatives of the order or on mechanical advantage. It does not follow that these foundations are trustworthy or that there has always been mechanical improvement in the wings. Degeneration is just as probable as progressive development. The actual course of phylogeny cannot be deduced from these considerations or from the data of morphology. It seems therefore desirable to attempt to ascertain what paleontological evidence...

Download or read book Mesozoic Biological Events and Ecosystems in East Asia written by S-C. Chang and published by Geological Society of London. This book was released on 2022-08-11 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesozoic Biological Events and Ecosystems in East Asia covers a wide range of topics, encompassing palaeoenvironments, palaeoecosystems and important vertebrate, invertebrate and plant fossils, some found in amber with excellent preservation of delicate morphological features. Fifty-three authors from a number of different disciplines – geochronology, palaeontology, stratigraphy, sedimentology, tectonics and geochemistry – contribute to the 18 articles in the volume. Well-preserved fossils and rocks continue to be found from marine and terrestrial sediments across East Asia. Over some years, the palaeontological and geological evidence discovered from this region has significantly improved our understanding of Mesozoic environments. In discussing feathered dinosaurs, primitive birds, early mammals, diverse insects, amber inclusions, the oldest-known flowers and research utilizing new, advanced methods, this volume explores Earth’s history in even greater detail. What other exciting discoveries are waiting to be unveiled in the future?

Download or read book Indian Insects written by S Ramani and published by CRC Press. This book was released on 2019-10-16 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most interesting and diverse group of organisms on earth, many of which are useful as pollinators of crops and wild plants while others are useful as natural enemies keeping pestiferous insects in check. It is important to conserve these insects for our survival and for this the diversity of insect species inhabiting the different ecosystems of our country must be known. The cornerstone to studies of any kind of organismal diversity is their taxonomic identity. Even after over two and half centuries of studies, so little is known of the insect wealth of our country. It has contributions from taxonomists who have been studying Indian insects for long, this book offers up to date information on many important groups of Indian insects seeking to fill the lacuna of a long felt need for a comprehensive work on the taxonomy of Indian insects. Salient features: Provides an up-to-date taxonomy of major insect groups of India Presents identification keys with illustrations of several important groups of Indian insects Gives a new insight into why insects are so abundant Addresses fundamental questions in mechanoreception and cross kingdom interactions using insects as model systems Indian Insects: Diversity and Science is a festschrift to Professor C. A. Viraktamath, an insect taxonomist par excellence. It has been designed to cater to the needs of academicians, researchers and students who wish to identify insects collected from local environments and will be an invaluable aid for those working in the areas of systematics, ecology, behaviour, diversity and the conservation of insects.

Download or read book Dragonflies and Damselflies written by Alex Cordoba-Aguilar and published by Oxford University Press. This book was released on 2023-01-05 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancement of our broader understanding of insect ecology and evolution. This new edition provides a critical summary of the major advances in these fields. The editors have carefully assembled a fresh set of contributions from a diverse geographic mix of both junior and senior researchers in dragonfly biology to offer new perspectives and paradigms as well as additional, unpublished data. These include theoretical and applied chapters (including those addressing conservation and monitoring) as well as a balance of emerging (e.g. molecular evolution) and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but is an essential source of knowledge that describes how different sets of evolutionary and ecological principles and ideas have been tested on a particular taxon. Dragonflies and Damselflies is suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, community ecology, and conservation biology. It will be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
