Medler INTRODUCTION HIS bulletin attempts to present as accurate and complete a T guide to the leafhoppers of Minnesota as possible within the limits of the material available for study. It is realized that cer- tain groups could not be treated completely because of the lack of available material. Nevertheless, it is hoped that in its present form this treatise will serve as a convenient and useful manual for the systematic and economic worker concerned with the forms of the upper Mississippi Valley. In all cases a reference to the original description of the species and genus is given. Keys are included for the separation of species, genera, and supergeneric groups. In addition to the keys a brief diagnostic description of the important characters of each species is given. Extended descriptions or long lists of references have been omitted since citations to this literature are available from other sources if ac- tually needed (Van Duzee, 1917). -

Triuridaceae J.P.M. van de Meerendonk Leyden) 1 The Triuridaceae 6 and 45 are a small family (c. genera, c. spp.) of very delicate, saprophytic, terrestrial, mostly dark-red coloured herbs growing in the deep shade of everwet tropical forest, entering the subtropics only in Japan and the Bonin Is. They are in Africa confined to restricted in the West and in areas are also continental SoutheastAsia remarkably rare, as yet only known from two localities in Assam and N. Thailand respectively.

A Comparison of the External Morphology and Functions of Labial Tip Sensilla in Semiaquatic Bugs (Hemiptera: Heteroptera: Gerromorpha)
Eur. J. Entomol. 111(2): 275–297, 2014 doi: 10.14411/eje.2014.033 ISSN 1210-5759 (print), 1802-8829 (online) A comparison of the external morphology and functions of labial tip sensilla in semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha) 1 2 JOLANTA BROŻeK and HERBERT ZeTTeL 1 Department of Zoology, Faculty of Biology and environmental Protection, University of Silesia, Bankowa 9, PL 40-007 Katowice, Poland; e-mail: [email protected] 2 Natural History Museum, entomological Department, Burgring 7, 1010 Vienna, Austria; e-mail: [email protected] Key words. Heteroptera, Gerromorpha, labial tip sensilla, pattern, morphology, function, apomorphic characters Abstract. The present study provides new data on the morphology and distribution of the labial tip sensilla of 41 species of 20 gerro- morphan (sub)families (Heteroptera: Gerromorpha) obtained using a scanning electron microscope. There are eleven morphologically distinct types of sensilla on the tip of the labium: four types of basiconic uniporous sensilla, two types of plate sensilla, one type of peg uniporous sensilla, peg-in-pit sensilla, dome-shaped sensilla, placoid multiporous sensilla and elongated placoid multiporous sub- apical sensilla. Based on their external structure, it is likely that these sensilla are thermo-hygrosensitive, chemosensitive and mechano- chemosensitive. There are three different designs of sensilla in the Gerromorpha: the basic design occurs in Mesoveliidae and Hebridae; the intermediate one is typical of Hydrometridae and Hermatobatidae, and the most specialized design in Macroveliidae, Veliidae and Gerridae. No new synapomorphies for Gerromorpha were identified in terms of the labial tip sensilla, multi-peg structures and shape of the labial tip, but eleven new diagnostic characters are recorded for clades currently recognized in this infraorder. -

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. -

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). -

Effects of Livestock Grazing on Aboveground Insect Communities In
Biodiversity and Conservation (2006) 15:2547–2564 Ó Springer 2006 DOI 10.1007/s10531-005-2786-9 -1 Effects of livestock grazing on aboveground insect communities in semi-arid grasslands of southeastern Arizona SANDRA J.

Box 105, Hermiston, Oregon 97838-7100, USA (e-mail: [email protected]; phone: +001-541-567-6337; fax: +001-541-567-2240) Received 22 June 2004; accepted in revised form 14 February 2005 Key words: Arizona, Grasslands, Insect communities, Insect conservation, Livestock grazing Abstract. Despite the importance of invertebrates in grassland ecosystems, few studies have examined how grassland invertebrates have been impacted by disturbances in the southwestern United States. These grasslands may be particularly sensitive to one common disturbance, livestock grazing, because they have not recently evolved in the presence of large herds of bison, an important mammalian herbivore. This study examined how livestock grazing influenced vegetation- associated insect communities in southeastern Arizona. Insect abundance, richness, diversity, community composition, and key environmental variables were compared between sites on active cattle ranches and sites on a 3160 ha sanctuary that has not been grazed by cattle for over 25 years. Vegetation-associated insect communities were found to be sensitive to livestock grazing. Overall abundance of these insects was lower on grazed grasslands, and certain insect orders appeared to be negatively affected by livestock grazing; beetles were less rich, flies were less diverse, and Hymenoptera were less rich and diverse on grazed sites. -
