Light Intensity on the Size of Bracken Frond Leaves
Site: Rushey Plain
Grid Reference: TQ 415 985
Hypothesis:
H0- there is no significant difference between the light intensity and the frond size of Bracken leaves between Rushey Plain 1 and Rushey Plain 2
H1- there is a significant difference between the light intensity of the frond size of Bracken leaves between Rushey Plain 1 and Rushey Plain 2
Research and rationale:
This study will aim to find a significant relationship between light intensity on the size of Bracken frond leaves and if varying amounts of light will cause a relative increase or decrease in the frond sizes of the Bracken plant. It will more over, measure if there is a more abundant, healthier growth of Bracken in shaded areas in comparison to areas with little to no overhead canopy.
Bracken (Pteridium aquilinum) is a type of fern that is found across the world. The growth of Bracken is known to be affected by a number of factors including the pH of the soil, soil moisture, light intensity, humidity and air temperature.
Bracken is said to grow in relatively acidic soil and is less competitive when the pH is higher. Likewise, Bracken is a good indicator of how moist the soil is and similarly how well drained. Bracken does not flourish well in water- logged areas and so therefore, most areas containing Bracken will have a good drainage system. The type of soil does not tend to affect Bracken growth, where it can be grown in normal soil, as well as sandy soil and heavy clay such as in forests. Bracken is more prominent in areas of high humidity and there is an increase in its growth were temperature’s are above eight degrees Celsius- as it is during the winter months that the leaves with a lack of chlorophyll, fail to photosynthesis as much and thus turn yellow/brown, wilt and fall off. They become Bracken litter on the floor and can still be seen lying there even 12 months after, when new shoots and spores have begun to develop.

    The definition of vegetation is plants considered collectively especially those found in a particular area or habitat. The amount of vegetation that occurs in soil depends on the type of habitat that the soil belongs to. Each habitat has inhibitors and prohibitions that affect the amount of vegetation that each plot of soil is capable of producing. Inhibitors of soil are plots that receive a decent amount of sunlight and precipitation; while prohibitors are soil erosion, temperature, lack of precipitation and P.H. Winthrop University’s research area is 325 acres; which includes a large wooded area, three successional plots, and 1.1 acre wetland area. The successional plots are 50 x 50 meters and each of the plots is five years apart in age. The oldest plot was originally created in 1989. In a previous study on the Chinese Loess Plateau to determine how physiochemical properties, microbial biomass, and enzyme activities changed the natural succession for abandoned farm land. The experiment involved aged and abandoned farmland from zero to fifty years old and the results were the PH was lower for the older farmland compared to the younger farmland.(Wang, Liu, Xue, Zhu, paragraph 1) Pertaining to the results of the past study, the objective of the study was to evaluate…

    The light was measured in a spot where there were vegetation which had leaves and long trunks. This was done to observe how much light could penetrate through the vegetation. A light meter was obtained and it was turned face down in a spot were there was moderate light to ensure a fair result. The light meter then showed the light intensity in units of flux. The results were recorded.…

    Indris are the largest kind of lemur in the world. The scientific name for the Indri is Indri indri, but another name for the indri is a Babakoto which means little father. The Indris has a black thick coat with patches of white fur. The indri ranges to become 64 to 72cm and the tail only reaches 5cm. They weigh between 6kg and 10kg at full growth. They only live for 15 to 22 years . There are no Indri in captivity but today they live in protected forest’s. In the Trophic level the Indri is a 2nd level consumer and they are herbivore. The Indris only eat fruit and plants. Their predators are snake, hawks and Fossa. Their lifestyle is diurnal which means that they are active during the day. The Indri live in groups called troops and are very sociable animals. They are also unique in that the female is more dominant then the male. These animal are endangered because of lose of they habitat. They are less than 10,000 indri left in the world. The Indri lives in the tropical forests and lowland jungles.…

    The research being conducted in this practical aims to look at the differing wavelengths of visible light, and which range produces the most photosynthetic activity in green land plants. Since these plants absorb red and blue lights the most readily, and chlorophyll a absorbs blue light the most out of any other wavelength, it is hypothesised that in this practical the most activity will be seen under the blue light (Hoober 1984).…

    Pea plants, along with many other plants and vegetables, are taken for granted. Without them, much of the world would be different and it would affect the planet in a negative manner. Therefore, it is necessary for plants to be able to grow. In this paper, there is information on seed germination and light’s effects on plants. These are important part of seeds’ growth and they were a part of the experiment that was performed and then analyzed in this paper. The experiment tested the color of light’s effect on an Alaskan pea plants’ growth throughout the course of fourteen days. The colors used in the experiment are red and green. Plants absorb red light and it is good for growth while plants reflect green light so it is not the most ideal light for growth.…

    “Brasenose Wood has a well defined coppice-with-standards structure and is one of the few English woods which is still actively managed by this traditional method. The greater part of the wood is an ancient remnant of Shotover Forest with a documented history dating back to the thirteenth century. The wood lies on poorly drained Kimmeridge clays but oolitic limestone occurs close to the south western boundary and the presence of lime-loving plants suggests that it outcrops elsewhere in the wood. The flora is exceptionally rich for a wood of this size with 221 recorded vascular plant…
