Drosophila Eye Development


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.




Photoreceptor Optics


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.

A Dictionary of Entomology


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.

The Man with the Compound Eyes


Book Description

When a tsunami sends a massive island made entirely of trash crashing into the Taiwanese coast, two very different people—an outcast from a mythical island and a woman on the verge of suicide—are united in ways they never could have imagined. Here is the English-language debut of a new and exciting award-winning voice from Taiwan, who has written an “astonishing” novel (The Independent) that is at once fantasy, reality, and dystopian environmental saga. Fifteen-year-old Atile’i—a native of Wayo Wayo, an island somewhere in the Pacific—has come of age. Following the custom of his people, he is set adrift as a sacrifice to the Sea God but, unlike those who have gone before him, Atile’i is determined to defy precedent and survive. His chances seem slim, but just as it appears that hope is lost, Atile’i comes across a sprawling trash vortex floating in the ocean and climbs onto it. Meanwhile, on the east coast of Taiwan, Alice, a college professor, is overcome with grief. Her husband and son are missing, having disappeared while hiking in the mountains near their home. Alice is so distraught that she decides to end her own life. But her plans are interrupted by a violent storm that causes the trash vortex to collide with the Taiwanese coast, bringing Atile’i along with it. Alice and Atile’i subsequently form an unlikely friendship that helps each of them come to terms with what they have lost. Together they set out to uncover the mystery of Alice’s lost family, following their footsteps into the mountains. Intertwined with Alice and Atile’i’s story are the lives of others affected by the tsunami, from environmentalists to Taiwan’s indigenous peoples—and, of course, the mysterious man with the compound eyes. A work of lyrical beauty that combines magical realism and environmental fable, The Man with the Compound Eyes is an incredible story about the bonds of family, the meaning of love, and the lasting effects of human destruction.
