    Laurentian Mixed Forest Province, Cliff/Talus System Summary

    CT Cliff and Talus System photo by M.D. Lee MN DNR Lake County, MN General Description Communities in the Cliff/Talus (CT) System are present on cliffs or talus slopes on steep- sided knobs, in river gorges, along lakeshores, and in other settings with sheer bedrock exposures. Often, cliffs and talus slopes are associated with one another because talus slopes are composed of rock fractured either from cliffs or from exposed bedrock on steep hillsides. The vegetation of CT communities is generally open. Lichens and moss- es are the dominant life forms, with vascular plants sparse or patchy because of scarcity of soil. In this classification, cliff communities are grouped by moisture and light regimes and by bedrock type, which are the major determinants of species composition. Cliff habitats range from warm and dry to cool and wet depending on cliff aspect, proximity to streams or lake shores, and presence of groundwater seepage on the cliff face. In the Laurentian Mixed Forest (LMF) Province, cliffs are formed most commonly of igneous bedrock, although cliffs on metamorphic rock are also common. Talus communities are classified according to amount of woody plant cover and moisture regime. In the LMF Province, CT communities are restricted mostly to the North Shore High- lands and Border Lakes subsections in NSU, where Precambrian bedrock is frequently at or just below the surface and topography is often rugged. Scattered cliffs are present in WSU and are likely in the Laurentian Uplands Subsection in NSU and the Littlefork- Vermilion Uplands Subsection in Northern Minnesota & Ontario Peatlands MOP, primar- ily along lakes and streams where water has exposed the underlying bedrock.

Prosta 290 D/2, 25-385 Kielce, Poland; [email protected] * Correspondence: [email protected] Simple Summary: Euryommatus mariae is a legendary weevil species in Europe, first described in the 19th century and not collected through the 20th century. Though rediscovered in the 21st century at few localities in Poland, Austria, and Germany, it remains one of the rarest of European weevils, and its biology is unknown. We present the first descriptions of the larva and pupa of E. mariae, and confirm its saproxylic lifestyle. The differences and similarities between immatures of E. mariae and the genera Coryssomerus, Cylindrocopturus and Eulechriopus are discussed, and a list of larval characters common to all Conoderitae is given. The characters of adult postabdomen are described and illustrated for the first time for diagnostic purposes. Our study confirmed the unusual structure of the male endophallus, equipped with an extremely long ejaculatory duct enclosed in a peculiar fibrous conduit, not seen in other weevils. We hypothesize that the extraordinarily long Citation: Gosik, R.; Wanat, M.; Bidas, and spiral spermathecal duct is the female’s evolutionary response to the male’s extremely long M.

This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

In 1998, the Canada thistle biocontrol stem-mining weevil Hadroplontus litura was introduced into a limited area in Minnesota with a resulting decline in Canada thistle populations. Although showing a preference for Canada thistle, initial host range testing of H. litura revealed that it attacked other native thistles. Before continuing biocontrol efforts with additional H. litura releases in Minnesota, we wanted to clarify whether H. litura would attack thistles native to Minnesota. The two objectives of our research were: 1.) determine whether H. litura could feed, oviposit and complete development on native thistles, and 2.) determine the phenology of native thistles in relation to Canada thistle. In no-choice tests, female H. litura accepted all native thistle species for oviposition and was able to complete development to the adult stage on swamp, field, tall, Flodman’s and wavy-leaved thistle. In Hill’s and the federally threatened Pitcher’s thistle, no adults were found in development tests.
