Essay about Lab Report: Bramble Leaf Morphology

Similar information has been explored in different studies. A previous study conducted showed that trees with smaller DBHs and greater canopy coverage allowed for an increase in species richness (Rannius T 2000). Furthermore, researchers have found that saplings across different species like the sugar maple exhibit greater growth in open canopies than saplings that are in closed canopies (Canndam C. 1998). Although these studies are important, the relationship between canopy size and DBH is still yet to be explored. In response to this lack of knowledge, we have conducted a study to further explore this correlation. Our hypothesis is that the larger the DBH size, the greater the amount of canopy coverage in a given area for the tree being studied.

Every forest has a story to tell. By looking closely at its habitants, that story can be interpreted. Much of this narrative is written in the trees: their age, their tolerance to shade, and the rate at which they grow are all characteristics that can imply a lot about their environment. Exploring these relationships and how they connect with each other can indicate the health and history of the land. Heiberg Forest, located in northern New York, was once used for agricultural purposes in the 1800-1900’s. (Nowak, Lecture Notes) Much of the land once used for farming was left to regrow back into a young forest. The life history of different tree species can be determined by examining the most common species in Heiberg.

By comparing the topography, soil moisture levels, relative humidity, and wind speed of the upland Savanna and Bottomland forest we will be able to compare and contrast between these two vegetation zones. The data collected in the investigation will be used to test the hypothesis that the bottomland forest has a higher degree of shrub layer cover than the savanna. The higher level of shrubs in the bottomland forest might be attributed to the space available for shrub layer species. In addition, the data collected will confirm that the bottomland forest has a higher tree density than the

This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were

The topography of the island is also of note. The west end of the island features a closed-canopy forest with more hardwood trees. The east end of the island is better characterized as a “boreal forest,” a term used to describe regions that are mostly covered by coniferous forests. It is good to note that the balsam fir is found on both ends of the island, but that samples used in the study from the west end of the island were, on average, older, but shorter, than those samples found on the east side of the island.

If I had lived during the Holocaust, the hardships would include lack of shelter, starvation, and survival. To start, people struggled to find a safe shelter. The book Milkweed is about a boy who has to change the locations of his shelter to be able to survive. I know that during this time period a lot of people who were jewish were taken to concentration camps were they were forced to work and were treated harshly. Because of this people had to change the location of their shelter to escape getting caught. Additionally, people also had to face the struggles of starvation. Since hitler and his nazis were killing off a lot of people, the people who owned food stores could no longer sell food. This meant that people couldn’t get the same amount

Happy Tuesday! Seedlings 2 began their day outside on the playground. We explored so many environmental objects and we moved in response to music and rhythm as we played with musical instruments with Ms. Clara. When we returned to our classroom, we explored floating green objects in our Sensory tub. Later we exercised our gross motor skills as we practice walking with our walker. I do hope you enjoy another fabulous day with Seedlings

In the past couple of decades, school sports have increased tremendous prevalence over the Unified States. Regardless of whether it be football, basketball, or hockey, as far back as the turn of the century, intercollegiate games have acquired an excess of income to their separate Universitys, and additionally expanding the prevalence of the School's organization. For instance, in a review directed by the Orland Sentinel, it was assessed that the University of Texas' Athletic Program had the most noteworthy income of some other University at $120,288,370 (The amount Income). However, with this expansive aggregate of cash, no school competitors are legitimately made up for their work. As per NCAA rules, "You are not qualified for interest in

We performed this experiment with five trees. On each tree we had three treatments: no thorns, normal amount of thorns, and a doubled amount of thorns. The branches were color coded with flagging tape according to the thorn density. Yellow was for super thorny branches, blue stripes indicated the control branches, and blue dots marked the thornless branches. We randomly designated which branches should be super thorny,

Fruit of the poisonous tree doctrine is a rule that evidence is gathered as a result of evidence gained in an illegal search of questioning cannot be used against the person searched or questioned even if the later evidence was gathered lawfully (Hall, 2016.) Generally evidence that is “tainted” by the prior illegal conduct is inadmissible (Hall, 2016.)

In comparison of the burned forest (forest A) and the unburned forest (forest C), it was found that the evidence rejected the null hypothesis that there would be a significant difference between the leaf litter depths of the two forest types (d.f. 49, p= 0.0036, t= 3.061). Further analysis shows that the unburned forest has a leaf litter depth mean of 2.97 cm and a standard deviation of 0.935. The burned forest was represented by a mean of 3.93 cm and a standard deviation of 1.26. The data collected also found that according to the Shapiro-Wilk test, there is not enough evidence to reject our null hypothesis that there would be a normal distribution in the leaf litter depths between the unburned forest (W=0.96, p=0.4341) and the burned forest

In fact, it was Plant E which only received indirect sunlight. Plant A, by day twenty, had only grown to twelve and one-fourth of an inch whereas Plant B had grown to seventeen inches. Throughout most of the experiment, Plant A was never the tallest plant except for day(s) four and six. I believe the reason for this is due to the fact that since Plant A had a constant rate of light, it processed way too much energy for it to be a healthy intake. Therefore, my hypothesis was proven

It was found that the trees with Spanish moss seemed to attract more animals than the ones without the moss. When starting the research for this project only two trees were being observed. This was a problem at the beginning because no animals would show up. So two more trees were to add to each group to make sure there was data collected. It was predicted that the trees without the Spanish moss would attract more animals than the trees with the moss (see figure 1). Unexpectedly, Spanish moss seemed to have no effect on the animals that it would live on it, they even seem to use the Spanish moss to build nests (see figure 2). Pictures were taken on the days that birds could be seen on the trees with the camera (see figures 3,4,5)

Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an oak tree, and needed a total of three different trees per group. Once three different trees were chosen, groups needed three shade leaves and three sun leaves of off each different tree. In total, each group should then end up with 18 leaves for testing. After collecting the leaves, we ran them through the LiCor 3100 leaf area meter to identify the area of each leaf. Major results found by the classes’ mutual data was each one of our p-values were greater than .05. This means that we failed to reject the null hypothesis. Thus, the lab results do not support our hypothesis that Quercus acclimation is greater than Acer SLW, size, and sinuosity.

Plant pathology is a science that studies plant diseases and attempts to improve the chances for survival of plants when they are faced with biotic and abiotic factors that cause disease. Plants will produce well as long as they get sufficient nutrient and moisture, light for photosynthesis and optimum temperature. However, plants also get sick. Sick plants produce poorly and the symptoms of disease will appear. The agents that cause disease in plants are similar to those causing disease in human and animals.
