Nitrogen Content in Riparian Arthropods Is Most Dependent on Allometry and Order
Wiesenborn: Nitrogen Contents in Riparian Arthropods 71 NITROGEN CONTENT IN RIPARIAN ARTHROPODS IS MOST DEPENDENT ON ALLOMETRY AND ORDER WILLIAM D. WIESENBORN U.S. Bureau of Reclamation, Lower Colorado Regional Office, P.O. Box 61470, Boulder City, NV 89006 ABSTRACT I investigated the contributions of body mass, order, family, and trophic level to nitrogen (N) content in riparian spiders and insects collected near the Colorado River in western Arizona. Most variation (97.2%) in N mass among arthropods was associated with the allometric effects of body mass. Nitrogen mass increased exponentially as body dry-mass increased. Significant variation (20.7%) in N mass adjusted for body mass was explained by arthropod order. Ad- justed N mass was highest in Orthoptera, Hymenoptera, Araneae, and Odonata and lowest in Coleoptera. Classifying arthropods by family compared with order did not explain signifi- cantly more variation (22.1%) in N content. Herbivore, predator, and detritivore trophic-levels across orders explained little variation (4.3%) in N mass adjusted for body mass. Within or- ders, N content differed only among trophic levels of Diptera. Adjusted N mass was highest in predaceous flies, intermediate in detritivorous flies, and lowest in phytophagous flies. Nitro- gen content in riparian spiders and insects is most dependent on allometry and order and least dependent on trophic level. I suggest the effects of allometry and order are due to exoskeleton thickness and composition. Foraging by vertebrate predators, such as insectivorous birds, may be affected by variation in N content among riparian arthropods. Key Words: nutrients, spiders, insects, trophic level, exoskeleton, cuticle RESUMEN Se investiguo las contribuciones de la masa de cuerpo, orden, familia y el nivel trófico al con- tenido de nitógeno (N) en arañas e insectos riparianos (que viven en la orilla del rio u otro cuerpo de agua) recolectadaos cerca del Rio Colorado en el oeste del estado de Arizona. -

What We Have Learned About the Bermudagrass Stem Maggot
WHAT WE HAVE LEARNED ABOUT THE BERMUDAGRASS STEM MAGGOT D.W. Hancock, W.G. Hudson, L.L. Baxter, and J.T. McCullers1 Abstract Since first being discovered in southern Georgia in July 2010, the bermudagrass stem maggot (BSM; Atherigona reversura Villeneuve) has infested and damaged forage bermudagrass (Cynodon dactylon) throughout the southeastern United States. Our objectives for this presentation were to summarize the available literature on this new, invasive species and provide additional insight from what is currently known about other Atherigona spp. The BSM, along with other Atherigona spp., are small, muscid flies native to Central and Southeast Asia. The adult fly of the BSM lays its eggs on bermudagrass leaves. Upon hatching, the BSM larva slips into the sheath, down the tiller, and penetrates the pseudostem at the first node. The BSM larva then feeds on the vascular tissue, sap, and (potentially) the subsequent decaying plant material before exiting the tiller, pupating in the soil, and emerging as a fly. As a result of the larval feeding, bermudagrass exhibits senescence and necrosis of the terminal leaves on the affected shoots. The affected leaves are easily pulled out of the sheath and show obvious damage near the affected node. In severe infestations, over 80% of the tillers in a given area may be affected. There is a paucity of information about the lifecycle of A. reversura and how it can be managed or controlled, but some information is available on basic larva behavior, fly physiology, and the potential differences in resistance among some bermudagrass varieties. Additional research is underway to better understand the lifecycle of this species, confirm and quantify the degree of preference A. -

Wilhelm Ostwald – the Scientist
ARTICLE-IN-A-BOX Wilhelm Ostwald – The Scientist Friedrich Wilhelm Ostwald was born on September 2, 1853 at Riga, Latvia, Russia to Gottfried Ostwald, a master cooper and Elisabeth Leuckel. He was the second son to his parents who both were descended from German immigrants. He had his early education at Riga. His subsequent education was at the University of Dorpat (now Tartu, Estonia) where he enrolled in 1872. At the university he studied chemistry under the tutelage of Carl ErnstHeinrich Schmidt (1822– 1894) who again was a pupil of Justus von Liebig. Besides Schmidt, Johannes Lemberg (1842– 1902) and Arthur von Oettingen (1836–1920) who were his teachers in physical chemistry were also principal influences. It was in 1877 that he defended his thesis ‘Volumchemische Studien über Affinität’. Subsequently he taught as Privatdozent for a couple of years. During this period, his personal life saw some changes as well. He wedded Helene von Reyher (1854–1946) in 1880. With Helene, he had three sons, and two daughters. Amongst his children, Wolfgang went on to become a famous colloid chemist. On the strength of recommendation from Dorpat, Ostwald was appointed as a Professor at Riga Polytechnicum in 1882. He worked on multiple applications of the law of mass action. He also conducted measurements in chemical reaction kinetics as well as conductivity of solutions. To this end, the pyknometer was developed which was used to determine the density of liquids. He also had a thermostat built and both of these were named after him. He was prolific in his teaching and research which helped establish a school of science at the university. -
Cheshire Wildlife Trust
Cheshire Wildlife Trust Heteroptera and Diptera surveys on the Manchester Mosses with PANTHEON analysis by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] on behalf of Lancashire and Cheshire Wildlife Trusts Version 1.0 September 2018 Lancashire Wildlife Trust Page 1 of 35 Abstract This report describes the results of a series of surveys on the Manchester mosslands covering heteroptera (shield bugs, plant bugs and allies), craneflies, hoverflies, and a number of other fly families. Sites covered are the Holcroft Moss reserve of Cheshire Wildlife Trust and the Astley, Cadishead and Little Woolden Moss reserves of Lancashire Wildlife Trust. A full list is given of the 615 species recorded and their distribution across the four sites. This species list is interpreted in terms of feeding guilds and habitat assemblages using the PANTHEON software developed by Natural England. This shows a strong representation in the sample of species associated with shaded woodland floor and tall sward and scrub. The national assemblage of peatland species is somewhat less well represented, but includes a higher proportion of rare or scarce species. A comparison is also made with PANTHEON results for similar surveys across a similar range of habitats in the Delamere Forest. This suggests that the invertebrate diversity value of the Manchester Mosses is rather less, perhaps as a result of their fragmented geography and proximity to past and present sources of transport and industrial pollution. Introduction The Manchester Mosses comprise several areas of lowland bog or mire embedded in the flat countryside between Warrington and Manchester. They include several areas designated as SSSIs in view of the highly distinctive and nationally important habitat, such as Risley Moss, Holcroft Moss, Bedford Moss, and Astley Moss. -

Lancs & Ches Muscidae & Fanniidae
The Diptera of Lancashire and Cheshire: Muscoidea, Part I by Phil Brighton 32, Wadeson Way, Croft, Warrington WA3 7JS [email protected] Version 1.0 21 December 2020 Summary This report provides a new regional checklist for the Diptera families Muscidae and Fannidae. Together with the families Anthomyiidae and Scathophagidae these constitute the superfamily Muscoidea. Overall statistics on recording activity are given by decade and hectad. Checklists are presented for each of the three Watsonian vice-counties 58, 59, and 60 detailing for each species the number of occurrences and the year of earliest and most recent record. A combined checklist showing distribution by the three vice-counties is also included, covering a total of 241 species, amounting to 68% of the current British checklist. Biodiversity metrics have been used to compare the pre-1970 and post-1970 data both in terms of the overall number of species and significant declines or increases in individual species. The Appendix reviews the national and regional conservation status of species is also discussed. Introduction manageable group for this latest regional review.
