    Systematic Entomology (2020), DOI: 10.1111/syen.12443 Protein-encoding ultraconserved elements provide a new phylogenomic perspective of Oestroidea flies (Diptera: Calyptratae) ELIANA BUENAVENTURA1,2 , MICHAEL W.

GONZÁLEZ2, ARIANNA THOMAS-CABIANCA5 andTORSTEN DIKOW2 1Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Germany, 2National Museum of Natural History, Smithsonian Institution, Washington, DC, U.S.A., 3The Jackson Laboratory, Bar Harbor, ME, U.S.A., 4Department of Biological Sciences, Wright State University, Dayton, OH, U.S.A. and 5Department of Environmental Science and Natural Resources, University of Alicante, Alicante, Spain Abstract. The diverse superfamily Oestroidea with more than 15 000 known species includes among others blow flies, flesh flies, bot flies and the diverse tachinid flies. Oestroidea exhibit strikingly divergent morphological and ecological traits, but even with a variety of data sources and inferences there is no consensus on the relationships among major Oestroidea lineages. Phylogenomic inferences derived from targeted enrichment of ultraconserved elements or UCEs have emerged as a promising method for resolving difficult phylogenetic problems at varying timescales. To reconstruct phylogenetic relationships among families of Oestroidea, we obtained UCE loci exclusively derived from the transcribed portion of the genome, making them suitable for larger and more integrative phylogenomic studies using other genomic and transcriptomic resources. We analysed datasets containing 37–2077 UCE loci from 98 representatives of all oestroid families (except Ulurumyiidae and Mystacinobiidae) and seven calyptrate outgroups, with a total concatenated aligned length between 10 and 550 Mb. About 35% of the sampled taxa consisted of museum specimens (2–92 years old), of which 85% resulted in successful UCE enrichment.

This is because they are originated from complex interaction between light and sophisticated nanostructures generated in the natural world. In addition, their inherent regular structures are one of the most conspicuous examples of non-equilibrium order formation. Structural colors are deeply connected with recent rapidly growing fields of photonics and have been extensively studied to clarify their peculiar optical phenomena. Their mechanisms are, in principle, of a purely physical origin, which differs considerably from the ordinary coloration mechanisms such as in pigments, dyes and metals, where the colors are produced by virtue of the energy consumption of light.

  • Insect Gears

[ Today 316 Abstract Vol 2:5 nsects have developed many structural modifications to ensure 317 their survival during the course of evolution. A recently discovered 2020 Spl. Iadaptation was the presence of gears in insect legs of Issus coleoptratus which they use for jumping and faster movements. In this paper, we have briefly described the modifications of hind legs Insect Gears in Issus and mechanism behind the working of insect gears. G. Sai Karthik1* and Vinod S. Kukanur2 Introduction 1*Dept of Entomology, Prof. Jayashankar Telangana State nsects are the most diversified organisms on the earth due to their capacity of flight and presence of three pairs of Agricultural University, Hyderabad, Telangana (500 030), India legs that helps in their better locomotion. Insect legs have 2International Crops Research Institute for Semi-Arid Tropics, I several structural modifications like large femur, strong tibia, Hyderabad, Telangana (502 324), India heavy musculature etc. that enable their faster movements to serve their various purposes. Insects show a wide range of modifications in legs that suits their lifestyle. One of such modification which was recently discovered is briefed here. A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, change the speed, creating a mechanical advantage. We humans think that we are pretty smart by inventing some dizzy array of machines and mechanisms that utilizes the so called ‘gears’ in their functioning, but Open Access evolution has once again outraged us, this time a million years ago.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
    NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

TEULON, TERRY R. HITCHINGS, VICTOR F. EASTOP, NICHOLAS A. MARTIN, MURRAY J. FLETCHER, MARLON A. W. STUFKENS, PAMELA J. DALE, Daniel BURCKHARDT, THOMAS R. BUCKLEY, STEVEN A. TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).
