Yanahan University of Illinois at Urbana-Champaign During the Pleistocene, glacial advances left a small gap in the northwestern corner of Illinois, southwestern Wisconsin, and northeastern Iowa, which were never covered by the advancing Pleistocene glaciers (Taylor et al. 2009, p. 8, fig. 2.2). This is the Driftless Area – and it is one of Illinois’ most unique natural regions, comprising little more than 1% of the state. Illinois’ Driftless Area harbors more than 30 threatened or endangered plant species, and several unique habitat types. Among these habitats are talus, or scree, slopes, some of which retain ice throughout the year. The talus slopes that retain ice through the summer, and thus form a habitat which rarely exceeds 50 °F, even when the surrounding air temperature is in the 90’s °F, are known as “algific slopes.” While there are numerous examples of algific slopes in Iowa and Wisconsin, this habitat is very rare in Illinois (fewer than ten truly algific sites are known in the state).

Este guia de identificação foi elaborado para auxiliar os técnicos e profissionais de várias áreas de conhecimento nos trabalhos de campo e nas vistorias técnicas realizadas pelo Ibama. É preciso esclarecer que este guia não pretende formar “especialista”, mesmo porque para tanto seriam necessários muitos anos de dedicação e aprendizado contínuo. Longe desse intuito, pretende- se apenas que este trabalho sirva para despertar o interesse quanto à conservação dos invertebrados de cavernas (meio hipógeo) e também daqueles que vivem no ambiente externo (meio epígeo).

  • The Beetle Fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and Distribution
    INSECTA MUNDI, Vol. 20, No. 3-4, September-December, 2006 165 The beetle fauna of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity and distribution Stewart B. Peck Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario K1S 5B6, Canada stewart_peck@carleton. ca Abstract. The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of Dominica and the Lesser Antilles in general. Of the species known to occur elsewhere, the largest numbers are shared with neighboring Guadeloupe (201), and then with South America (126), Puerto Rico (113), Cuba (107), and Mexico-Central America (108). The Antillean island chain probably represents the main avenue of natural overwater dispersal via intermediate stepping-stone islands. The distributional patterns of the species shared with Dominica and elsewhere in the Caribbean suggest stages in a dynamic taxon cycle of species origin, range expansion, distribution contraction, and re-speciation.

  • Coleoptera: Carabidae) Diversity
    VEGETATIVE COMMUNITIES AS INDICATORS OF GROUND BEETLE (COLEOPTERA: CARABIDAE) DIVERSITY BY ALAN D. YANAHAN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Master’s Committee: Dr. Steven J. Taylor, Chair, Director of Research Adjunct Assistant Professor Sam W. Heads Associate Professor Andrew V. Suarez ABSTRACT Formally assessing biodiversity can be a daunting if not impossible task. Subsequently, specific taxa are often chosen as indicators of patterns of diversity as a whole. Mapping the locations of indicator taxa can inform conservation planning by identifying land units for management strategies. For this approach to be successful, though, land units must be effective spatial representations of the species assemblages present on the landscape. In this study, I determined whether land units classified by vegetative communities predicted the community structure of a diverse group of invertebrates—the ground beetles (Coleoptera: Carabidae). Specifically, that (1) land units of the same classification contained similar carabid species assemblages and that (2) differences in species structure were correlated with variation in land unit characteristics, including canopy and ground cover, vegetation structure, tree density, leaf litter depth, and soil moisture. The study site, the Braidwood Dunes and Savanna Nature Preserve in Will County, Illinois is a mosaic of differing land units. Beetles were sampled continuously via pitfall trapping across an entire active season from 2011–2012. Land unit characteristics were measured in July 2012. Nonmetric multidimensional scaling (NMDS) ordinated the land units by their carabid assemblages into five ecologically meaningful clusters: disturbed, marsh, prairie, restoration, and savanna.

  • A Genus-Level Supertree of Adephaga (Coleoptera) Rolf G
    ARTICLE IN PRESS Organisms, Diversity & Evolution 7 (2008) 255–269 www.elsevier.de/ode A genus-level supertree of Adephaga (Coleoptera) Rolf G. Beutela,Ã, Ignacio Riberab, Olaf R.P. Bininda-Emondsa aInstitut fu¨r Spezielle Zoologie und Evolutionsbiologie, FSU Jena, Germany bMuseo Nacional de Ciencias Naturales, Madrid, Spain Received 14 October 2005; accepted 17 May 2006 Abstract A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy. To overcome problems associated with both the size of the group and the comparative paucity of available information, our analysis was made at the genus level (requiring synonymizing taxa at different levels across the trees) and used Safe Taxonomic Reduction to remove especially poorly known species. The final supertree contained 401 genera, making it the most comprehensive phylogenetic estimate yet published for the group. Interrelationships among the families are well resolved. Gyrinidae constitute the basal sister group, Haliplidae appear as the sister taxon of Geadephaga+ Dytiscoidea, Noteridae are the sister group of the remaining Dytiscoidea, Amphizoidae and Aspidytidae are sister groups, and Hygrobiidae forms a clade with Dytiscidae. Resolution within the species-rich Dytiscidae is generally high, but some relations remain unclear. Trachypachidae are the sister group of Carabidae (including Rhysodidae), in contrast to a proposed sister-group relationship between Trachypachidae and Dytiscoidea. Carabidae are only monophyletic with the inclusion of a non-monophyletic Rhysodidae, but resolution within this megadiverse group is generally low. Non-monophyly of Rhysodidae is extremely unlikely from a morphological point of view, and this group remains the greatest enigma in adephagan systematics.
