Leaf Litter Decomposition - Assignment Example Moreover, the experiment expected the tree species not to harbour the different soil animals. The maple and European Buckthorn are initially wet. Eventually they become very wet implying that the tree species harbour the soil animals. On the other hand, the maple and the European Buckthorn are greener and in regular sizes but eventually they decompose. This implies that the tree species decomposed. 2. Discuss what factors, that you observed, that may contribute leaf decomposition. What factors may contribute but were not measured? What was the average (&standard deviation) mass lost for each species? Where did the mass loss go? The observed factors that contribute to decomposition are the soil moisture and the plant composition. Temperature is also a factor which contributes to decomposition but it was not considered in this experiment. The wood decay is associated with the decay of the roots. The roots are the sole suppliers of moisture and nutrients to the entire plant hence they impact on the development of roots. Thus, the decay rates of woods will be similar to that of the leaves since the leaves obtain moisture and nutrients from the woods; whenever the woods are affected, the leaves are equally affected. Logging of trees results to the release of significant amounts of carbon dioxide into the atmosphere. Thus, the rate of decomposition of the floor area is relatively lower than normal since the presence of lignin in the leaves lowers the decomposition rate. The concepts of this experiment fully relates with the concepts of a composting program such as the one found in the City of Toronto since everything revolves around composting. Thus, composting can be defined us the natural process or procedures which are meant to decompose the organic substances into a one rich soil which can be named as the compost. This experiment describes the concept such as

The leadership style of Catherine the Great Research Paper

The leadership style of Catherine the Great - Research Paper Example The empress Catherine II is one of the brightest phenomena of the Russian history. The first half of her life, up to the accession to the throne, is represented as a series of fortunes, which did not depend on personal qualities of the modest German princess. But she managed to play the results of each of her successes in the best way, showing the rare ability to overcome any constraining circumstances as well as a moral ban, if was necessary for the achievement of a specific goal. The second half of the biography of Catherine The Great, a Russian Empress, is a series of the episodes, which arose spontaneously, not due to someones conscious will, and quite often had the most improbable endings. A motley round dance of events, in which the wisest plans and projects stuck and broke up, and instinctively made situational decisions often led to historically important consequences. This chaotic kaleidoscope developed a majestic picture of an eminence of the Russian Empire. Having headed t he triumph of her second homeland, the Empress Catherine II occupied a deserved place among historical heroes (Cronin, 1978). Catherine was not tall, but always held her chin highly lifted, and her back ideally straight. One her glance was enough to show his place to an impudent. â€Å"The double doors opened and the Empress appeared. I have said that she was quite small, and yet on the days when she made her public appearances, with her head held high, her eagle-like stare and a countenance accustomed to command, all this gave her such an air of majesty that to me she might have been Queen of the World; she wore the sashes of three orders, and her costume was both simple and regal; it consisted of a muslin tunic embroidered with gold fastened by a diamond belt, and the full sleeves were folded back in the Asiatic style. Over this tunic she wore a red velvet dolman with very short sleeves. The bonnet which held her white hair was not decorated with ribbons, but with the
