DROSOPHILA INFORMATION SERVICE 70 July 1991 Material contributed by DROSOPHILA WORKERS and arranged by James N. Thompson jr. Material presented here should not be used in publications without the consent of the author. prepared at Department of Zoology University of Oklahoma Norman, Oklahoma 73019 Drosophila Information Service Number 70 July 1991 Prepared at the Department of Zoology University of Oklahoma Norman, Oklahoma 73019 U.S.A. 2 DIS 70 (July 1991) Preface Dear Colleagues, I have learned a great deal and corresponded with many creative and knowledgeable people since assumng the editorship of Drosophila Information Servce last fall. It is hard to follow the outstanding editorial work of people lie Edward Novitski and Philip Hedrick, but I hope to live up to the example they have set. As you are probably aware, the last regular issue was DIS 67 (1988), and we have devoted this issue to printing the large number of research reports, technique notes, and new mutant descriptions that have accumulated since then. I hope you fid many valuable pieces of information in these pages, and I welcome your advice and ideas about ways to improve future issues. Several initiatives are underway. In this issue, I include a form to solicit directory information, and an updated directory wi be included in the next issue. A DIS editorial board of experienced Drosophila researchers is being formed to help recommend and evaluate material for DIS. Their enthusiasm and complementary areas of expertise wi help keep DIS a timely source of inormal communication for Drosophila researchers in all fields and countries. In addition, we are interested in eventually producing a computer diskette version of the DIS text. One goal is to be able to distribute a diskette version, as well as the printed copy of each issue, to intêrested individuals. A computerized subject index to DIS research and technical notes is also under consideration. Future issues wil also reprint the material distributed by way of the electronic Drosophila Inormation Newsletter (DIN), which is described elsewhere in this issue. I strongly believe, however, that the traditional printed copy of DIS, with its ilustrations and ready accessibility, remains an important product. I appreciate the support shown by the Drosophia Board for this project. The current composition of the Board is listed separately. The production of DIS 70 could not have been completed without the generous efforts of many people, most working in a voluntary capacity. Jean Ware, Caroline Tawes, Carolee Frank, and Sue Rollin did the complex word processing of manuscripts and mailing lists; Laura Jackson, April Sholl, and James Rutter helped organize lists and proof articles; Coral McCallster assisted in preparing the ilustrations and working with the University of Oklahoma printing servces; and Jenna Hellack worked dilgently to prepare the tables, paste up the arork, and help me inure that the final version was as accurately prepared as possible. We now realze that we did many things the "hard way", and the next issue will be easier. We appreciate the patience of those who have corresponded with us in this transition, and I apologize for any errors I have made in putting this issue together. I invite you to let me know what can be done to improve the usefulness of DIS as an inormal source of communication among Drosophila researchers. James N. Thompson, jr.

The Genetical Society of Great Britain THEGENETICS OF DROSOPHILA SUBOBSCURA POPULATIONS XV.EFFECTIVE SIZE OF A NATURAL POPULATION ESTIMATED BY THREE INDEPENDENT METHODS MICHAEL BEGON*, COSTAS B. KRIMBASt, and MICHAEL LOUKASt * Department of Zoology, University of Liverpool, Liverpool L69 3BX, U.K; t Department of Genetics, Agricultural College of Athens, Votanikos, Athens, Greece Received27.ii.80 SUMMARY An estimate is presented of the effective size of a natural, Greek population of Drosophila subobscura, based on data on lethal allelism. It is compared with further estimates for the same population obtained from newly-reported data by the "temporal" and the "ecological" methods. The lethal allelism and ecological estimates both suggest that the population is extremely large and effectively infinite. The conclusions from the temporal method conform to this, with the exception of data from two loci: Est-5 and Aph. Directional selection at these loci is therefore suggested. Each method is described and explained, and their validity discussed. The results are compared with the few previous estimates of effective population size. 1. INTRODUCTION POPULATION genetics theories, in general, deal with "ideal" populations, which are closed, of constant size, have discrete generations, random mating (including seif-fertilisation at random), and a random distribution of family sizes. Effective population number, Ne—a concept developed by Wright (1931, 1938)—relates theory to practice, and, essentially, is the size of the ideal population with which an actual population can be equated genetically. Thus Wright (1969) described the estimation of Ne as ".

    Cytogenetic Mapping of Enzyme Loci on Chromosomes J and U of Drosophila Subobscura

    Copyright 0 1984 by the Genetics Society of America CYTOGENETIC MAPPING OF ENZYME LOCI ON CHROMOSOMES J AND U OF DROSOPHILA SUBOBSCURA W. PINSKER AND D. SPERLICH Lehrstuhl fur Populationsgenetik, Institut fur Biologie 11, Universitat Tubingen, Auf der Morgenstelle 28, 0-7400Tubingen, Federal Republic of Germany Manuscript received April 24, 1984 Revised copy accepted July 20, 1984 ABSTRACT Enzyme loci located on chromosome J and U were mapped cytologically by means of a Y translocation technique. A linkage map of the two chromosomes was established in a parallel experiment and the recombination frequency in different regions of the chromosomes determined. A comparison of the cyto- genetic localization of the enzyme genes in D. subobscura and D. melanogaster indicates that many paracentric inversions must have taken place in the course of divergent evolution. However, no displacements of genes from one element to another due to pericentric inversions, reciprocal translocations or transpos- ing elements can be observed. In spite of the large number of structural rear- rangements that have occurred in the phylogeny of the genus Drosophila, gross similarities of banding pattern in homologous regions of the chromosomes of the two species become apparent. ITH the introduction of gel electrophoresis, enzyme loci have become W very important marker genes for population genetic studies. Allozyme variation has proved especially useful for the estimation of the amount of genetic variation and for the calculation of genetic relationship between pop- ulations, species and other taxa. In addition, a number of studies have been devoted to the search for nonrandom associations between alleles of different loci or linkage disequilibrium, maintained by selective forces favoring certain allele associations by epistatic interaction.

Six immigrant species are added to the list of Drosophilidae of Hawaii. They are: Amiota sp, Drosophila bizonata Kikkawa and Peng, D. nasutoides Okada, Hirtodrosophila sp. nr. unicolorata Wheeler, Scaptodrosophila sp., and Scaptomyza pallida (Zetterstedt). Seven new island records of previously established species are also documented. An annotated list of the 32 immigrant species of Drosophilidae established in Hawaii is provided, with the earliest confirmed year of detection for each species. Key words: Drosophilidae, Hawaii, Distribution The family Drosophilidae consists of 3950 valid species (Brake and Bächli 2008). With 559 endemic species (O’Grady et al. 2009), and an estimated 900-1000 in total, the Hawai- ian Islands have the highest regional drosophilid species diversity globally. Five species of immigrant Drosophilidae were listed as occurring in Hawaii by early authors (Sturtevant 1921, Bryan 1934), but most of these records were later shown to be misidentifications. Zimmerman (1943) was the first to document thoroughly the immigrant Hawaiian drosophilid fauna, based on available material in collections and field surveying. He pointed out that the species of Drosophila recorded in early literature as D.

For example, several drosophilids and other ectotherms increase in body and wing size at higher latitudes. Here we compare evolution in an ancestral European and a recently introduced (North America) cline in wing size and shape in Drosophila subobscura.We show that clinal variation in wing size, spanning more than 15 degrees of latitude, has evolved in less than two decades. In females from Europe and North America, the clines are statistically indistinguishable however the cline for North American males is significantly shallower than that for European males. We document that while overall patterns of wing size are similar on two continents, the European cline is obtained largely through changing the proximal portion of the wing, whereas the North American cline is largely in the distal portion. We use data from sites collected in 1986/1988 (Pegueroles et al. 1995) and our 1997 collections to compare synchronic (divergence between contemporary populations that share a common ancestor) and allochronic (changes over time within a population) estimates of the rates of evolution.

    Drosophila Subobscura Short Sperm Have No Biochemical Incompatibilities with Fertilization Maria Enrica Pasini*

    The Open Entomology Journal, 2010, 4, 25-29 25 Open Access Drosophila subobscura Short Sperm have no Biochemical Incompatibilities with Fertilization Maria Enrica Pasini* Università degli Studi di Milano, Dipartimento di Scienze Biomolecolari e Biotecnologie, Via Celoria, 26-20133 Milano, Italy Abstract: Drosophila obscura group species produce two distinct sizes of nucleated sperm that differ only in head and tail lenghts. Between both sperm there is no differences in location of the acrosome and flagellum during spermiogenesis where each sperm type develops in its own bundle. Fertile sperm accumulate in the seminal vesicles. Fertilization is ex- clusively monospermic and in a previous study we suggested that both types of sperm are fertilization-competent on the basis of similar DNA content and storage in females also if morph variations are consistent with a fertilization-related se- lection for optimal sperm size. This assumption is in agreement with previous studies that demonstrated that only long sperm fertilize eggs. In this study fertilization of Drosophila subobscura is examined using anti-sperm surface -N- acetylhexosaminidases and -L-fucosidase antibodies. Beta hexosaminidases are intrinsic proteins of the sperm plasma membrane in spermomomorphic species of the melanogaster group closely related to Drosophila melanogaster. These enzymes had been previously identified as putative receptors for glycoconjugates of the egg surface, structurally and func- tionally conserved. Here their localization has been investigated in Drosophila subobscura. Consistent with our previ- ous study, short and long sperm are functionally equivalent. More data are needed to clarify the consequences and adapta- tive significance of morph variations. Keywords: Drosophila, reproduction, sperm dimorphism, gametes.

Carson,1 Francisca C. Val,2 and Marshall R. Wheeler3 Abstract. A 1977 collection of Drosophilidae from 3 major islands of the Galapagos yielded 774 specimens. Of 10 species not recorded previously, 2 are new and are here described. One of these appears to be characteristic of the arid zone in Isla Santa Cruz but cannot be considered endemic until comparable continental habitats are studied. Of the 15 species found, 7 are cos­ mopolitan and 6 are well-known Neotropical species, suggesting an affinity to Ecuador. We con­ clude that the drosophilid fauna of the Galapagos is depauperate and consider earlier suggestions that a rich fauna exists to be erroneous. In the last 25 years, faunal surveys ofthe world Drosophilidae have produced many surprises.
