Effects of white-tailed deer herbivory on a tallgrass prairie remnant

Gooch, Scott 11 January 2010 (has links)
A study was conducted to determine what impact high white-tailed deer (Odocoileus virginianus) densities were having on the native grasslands of a tallgrass: aspen forest tract embedded within an agro-urban setting. Due to excessive spring moisture, row-crops were unavailable the first year. Using microhistological fecal analysis to determine dietary composition, deer were assessed to be placing the site’s favoured native plant species at risk of extirpation. Measuring woody stem abundance and height along and near the prairie: forest ecotone, deer were found to restructure woody growth but not directly influence encroachment rates. Indirectly, however, deer facilitated forest encroachment and prairie degradation through seed dispersal, nitrogen deposition, gap-dynamics, and trampling. Comparing dietary composition to nutritional data, deer grazed to maximize fitness, selecting foods high in IVDMD, minimizing energy expenditure, and optimizing CP. High crop CP was offset by intensively grazing particular native plants. ADF was an effective nutritional marker, not AIA.

Zelené chování obchodních řetězců (TESCO, Penny, Kaufland) / Green behavior of retail chains (TESCO, Penny, Kaufland)

PRAŽMOVÁ, Andrea January 2017 (has links)
The thesis deals with the application of green marketing, respectively Green behaviour of retail chains Tesco Stores, Penny Market and Kaufland Czech Republic in the territory of the regional city České Budějovice. The main aim is thus to determine whether these retail chains use green marketing and behaviour to what extent, based on the set of indicators and whether the customers of these chains reflect green marketing and behaviour in their purchasing decisions. The theoretical part is focused on definitions of basic and related concepts such as green marketing, green economy, customer purchasing behaviour and theoretical definitions of selected indicators of green behaviour. The practical part summarizes the information obtained from interviews with representatives of retail chains and analyse customer behaviour through a questionnaire survey. The main finding of the thesis is that although retail chains use green marketing, customer's purchasing decisions is not affected by this type of marketing. Customers prefer a price range and distance to stores from the residence or from the working place. The thesis also found that each chain has its clients, who have the same features of behaviour.
