The Investment Plan – Purchase Service Cars in Mann+Hummel (CZ), ltd. Company

Tato práce je zaměřena na podnikatelský záměr, který se zaměří na nákup služebních vozů ve vybrané společnosti. Bakalářská práce je rozdělena do tří hlavních částí, přičemž první se zabývá teoretickými poznatky z oblasti podniku a financování daného záměru. Tyto poznatky jsou následně využity v analýze současného stavu u konkrétní společnosti. Třetí část se věnuje vlastním návrhům řešení.This writing is focused on business plan, which focused on purchase service cars of the selected company. The thesis (dissertation) is divided into three main parts. The first is focusing on theoretical knowledge of about company and finance plan. This findings are applied in analysis actual state of company. The third part will look at own suggested solutions.

Climate shapes the spatiotemporal variation in color morph diversity and composition across the distribution range of Chrysomela lapponica leaf beetle

Color polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing environments. We explored the color morph diversity and composition in a Chrysomela lapponica leaf beetle across its entire distribution range to test the hypothesis that environmental and climatic variables shape spatiotemporal variation in the phenotypic structure of a polymorphic species. We obtained information on 13 617 specimens of this beetle from museums, private collections, and websites. These specimens (collected from 1830-2020) originated from 959 localities spanning 33 degrees latitude, 178 degrees longitude, and 4200 m altitude. We classified the beetles into five color morphs and searched for environmental factors that could explain the variation in the level of polymorphism (quantified by the Shannon diversity index) and in the relative frequencies of individual color morphs. The highest level of polymorphism was found at high latitudes and altitudes. The color morphs differed in their climatic requirements; composition of colour morphs was independent of the geographic distance that separated populations but changed with collection year, longitude, mean July temperature and between-year temperature fluctuations. The proportion of melanic beetles, in line with the thermal melanism hypothesis, increased with increasing latitude and altitude and decreased with increasing climate seasonality. Melanic morph frequencies also declined during the past century, but only at high latitudes and altitudes where recent climate warming was especially strong. The observed patterns suggest that color polymorphism is especially advantageous for populations inhabiting unpredictable environments, presumably due to the different climatic requirements of coexisting color morphs

Pilemostoma Desbroches 1891

<i>Pilemostoma</i> Desbroches, 1891 <p> <i>Cassida</i> sg. <i>Pilemostoma</i> Desbrochers (1891): 14 (type species: <i>Cassida fastuosa</i> Schaller, 1783, by monotypy); Hincks (1952): 339; Seeno and Wilcox (1982): 177.</p> <p> <i>Pilemostoma</i>: Spaeth (1914b): 89; Spaeth and Reitter (1926): 20; Borowiec (1999): 314.</p> <p> <i>Glyphocassis</i> Spaeth, 1914 is a genus very close to <i>Pilemostoma</i>. Both genera have similar body shape and elytral pattern. <i>Glyphocassis</i> is divided into two subgenera: the nominotypical subgenus with one species and <i>Hebdomecosta</i> Spaeth, 1915 with two species. The nominotypical subgenus shares many characters with <i>Pilemostoma</i>: deep antennal grooves, marginalia forming gutter, tarsal claws toothed basally and elongate. It differs in having an elongate prosternal collar with angulate sides (short and without angulation in <i>Pilemostoma</i>); an antennal groove bordered externally by a sharp carina (by an obtuse carina in <i>Pilemostoma</i>) and a marginalia of pronotum and elytra impunctate (punctate in <i>Pilemostoma</i>). Both genera are also separated geographically: <i>Glyphocassis</i> s. str. occurs in S China, NE India, and Indochina, while <i>Pilemostoma</i> is known exclusively from the Palaearctis. <i>Hebdomecosta</i> is Palaearctic like <i>Pilemostoma</i> but differs in simple tarsal claws; short, circular body and impunctate marginalia.</p> <p> Both genera also have different feeding habits. <i>Glyphocassis</i> feeds exclusively on Convolvulaceae (Kalaichelvan <i>et al.</i> 2004; Lee & Cho 2006) while <i>Pilemostoma</i> is associated with Asteraceae (Brovdij 1983; Sekerka 2006). Based on the characters mentioned above I treat <i>Pilemostoma</i> as an independent genus close to <i>Glyphocassis</i>.</p>Published as part of <i>Sekerka, Lukáš, 2008, Revision of the genus Pilemostoma Desbroches, 1891 (Coleoptera: Chrysomelidae: Cassidinae: Cassidini), pp. 40-48 in Zootaxa 1859</i> on page 41, DOI: <a href="http://zenodo.org/record/274450">10.5281/zenodo.274450</a&gt
