Book Description
1 Kevin Moses It is now 25 years since the study of the development of the compound eye in Drosophila really began with a classic paper (Ready et al. 1976). In 1864, August Weismann published a monograph on the development of Diptera and included some beautiful drawings of the developing imaginal discs (Weismann 1864). One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a regular pattern of clustered cells from an anterior domain without such a pattern. Weismann suggested that these clusters were the precursors of the adult ommatidia and that the line marks the anterior edge of the eye. In his first suggestion he was absolutely correct - in his second he was wrong. The vertical line shown was not the anterior edge of the eye, but the anterior edge of a moving wave of patterning and cell type specification that 112 years later (1976) Ready, Hansen and Benzer would name the "morphogenetic furrow". While it is too late to hear from August Weismann, it is a particular pleasure to be able to include a chapter in this Volume from the first author of that 1976 paper: Don Ready! These past 25 years have seen an astonishing explosion in the study of the fly eye (see Fig.

Book Description
How much of Earth's surface is covered by water? How do the northern lights get their colors? Planet Earth has been home to mankind for hundreds of thousands of years and while scientists have learned a lot about it, they're still unraveling many of its mysteries. B is for Blue Planet: An Earth Science Alphabet explains what we do know about our planet and what more we have to learn. Examine Earth's diverse ecosystems (deserts), discover geological wonders (karst caves), learn about weather phenomena (hurricanes), and much more. Ruth Strother has been in the publishing industry for more than twenty years and is the author of fifteen books for children. She also wrote Sleeping Bear's W is for Woof: A Dog Alphabet. Ruth lives in Southern California. Bob Marstall was a K-12 art teacher for many years, and today he is an award-winning children's book illustrator. He tours all over the country, lecturing in schools on the integration of art and science. Bob lives in Northampton, Massachusetts.

Book Description
The above consideration indicates that at present many of the experi mental facts on PS in animals can be quantitatively explained within the limits of the "universal" photoreceptor membrane concept. Of course, existence of preferential orientation of the absorbing dipoles in the tubuli of the rhabdomeres can not be totally rejected. We hope that the concept of the "universal" photoreceptor membrane may serve as the useful instrument when dealing with newly discovered properties of visual cells so that true mechanisms of electrical and optical coupling will be searched for instead of assumptions being made on additional properties of the photoreceptor membrane in every new animal under study. 5. Absorption Spectrum of the Universal Photoreceptor Membrane and Spectral Sensitivity of the Photoreceptor 5. 1 Preliminary Notes It seems nearly self-evident that the absorption spectrum of the pho toreceptor membrane coincides exactly with that of the visual pigment it contains. Hence, the membrane must exhibit three bands of absorp tion - the principal band with its peak within the limits of visible spectrum (or a-peak); the secondary band between 340 and 380 nm (S peak); and the third, protein band, in the ultraviolet (UV) at 280 nm (COLLINS et al. , 1952). The main peak of absorption is located within the range 433-575 nm for retinol-based pigments and between 438 and 620 nm for 3-dehydroretinol-based pigments, the position of Amax de pending on many ecological factors.

Book Description
"This book is a comprehensive, fully cross-referenced collection of over 28,000 terms, names and phrases used in entomology, incorporating an estimated 43,000 definitions. It is the only listing which covers insect anatomy, behaviour, biology, ecology, histology, molecular biology, morphology, pest management, taxonomy and systematics. The origin, etymology, part of speech and definition of each term and phrase are all provided, including the language, meaning or root of each term and constituent parts. Where meanings have changed, or terms have been borrowed from other disciplines, the most current usage is indicated. The common names of insects, their scientific binomen and taxonomic classification are provided, with diagnoses of pest species in many cases. All insect order, suborder, superfamily, family and subfamily names are given, together with the diagnostic features of orders and families. Names of deceased entomologists, or scientists from other fields who have contributed to entomology are included, with the citation for their biography or obituary. The list of names is global, including entomologists from Asia, whose research has often been neglected by western scientists. This book is an essential reference source for all professionals and students of entomology and related disciplines."--p. [4] of cover.

Book Description
Documents morphology, taxonomy, phylogeny, evolutionary changes, and interactions of 23 orders of insects from the Middle Jurassic and Early Cretaceous faunas in Northern China This book showcases 23 different orders of insect fossils from the Mid Mesozoic period (165 to 125 Ma) that were discovered in Northeastern China. It covers not only their taxonomy and morphology, but also their potential implications on natural sciences, such as phylogeny, function, interaction, evolution, and ecology. It covers fossil sites; paleogeology; co-existing animals and plants in well-balanced eco-systems; insects in the spotlight; morphological evolution and functional development; and interactions of insects with co-existing plants, vertebrates, and other insects. The book also includes many elegant and beautiful photographs, line drawings, and 3-D reconstructions of fossilized and extant insects. Rhythms of Insect Evolution: Evidence from the Jurassic and Cretaceous in Northern China features chapter coverage of such insects as the: Ephemeroptera; Odonata; Blattaria; Isoptera; Orthoptera; Notoptera; Dermaptera; Chresmodidae; Phasmatodea; Plecoptera; Psocoptera; Homoptera; Heteroptera; Megaloptera; Raphidioptera; Neuroptera; Coleoptera; Hymenoptera Diptera; Mecoptera; Siphonaptera; Trichoptera and Lepidoptera. Combines academic natural science, popular science, and artistic presentation to illustrate rhythms of evolution for fossil insects from the Mid Mesozoic of Northern China Documents morphology, taxonomy, phylogeny, and evolutionary changes of 23 orders of insects from the Middle Jurassic and Early Cretaceous faunas in Northern China Presents interactions of insects with plants, vertebrates, and other insects based on well-preserved fossil evidence Uses photos of extant insects and plants, fossil and amber specimens, line drawings, and 3-D computer-generated reconstruction artworks to give readers clear and enjoyable impressions of the scientific findings Introduces insect-related stories from western and Chinese culture in text or sidebars to give global readers broader exposures Rhythms of Insect Evolution: Evidence from the Jurassic and Cretaceous in Northern China will appeal to entomologists, evolutionists, paleontologists, paleoecologists, and natural scientists.
