(Ecology) Plant Competition - Lab Report Example Hence, it is logical to think that as the density of the plant increases, the more intense the competition becomes. In fact, this was demonstrated by Kothari et al. (1974) on Dichanthium annulatum, a dominant perennial grass species. It was observed in the study that as the number of plants increased from 17 to 135 individuals per meter-squared of land, the mean dry weight and nitrogen content per D. annulanum significantly decreased as compared to the other set-ups with lower plant densities. Meanwhile, interspecific competition refers to the interaction between two different plant species vying for the same resources (Freedman, 2011). Crops interspersed with weeds would be a good example of interspecific competition. Those species equipped with the least capacity to compete for the same environmental supply has to adapt or die eventually (Went, 1973). One of the earliest experimental investigations which catalogued the existence of competition within the floral community was conduc ted by Clements et al. (1929). Clements and his team planted sunflower, wheat, potatoes, and other plants species in varying distances with each other. Height (cm), leaf area (cm2), and dry weight (g) were then taken 80 days after planting (Clements et al., 1929). Results of the experiment indicated that the closer the plants are to each other, the more apparent growth inhibition becomes. Interestingly, increasing the number of plants per plot resulted to an overall production reaching a maximum value, which did not change even if spacing was decreased (Clements et al., 1929). It was also noted that growth of all plants within the same plot were equally inhibited (Clements et al., 1929). However, a different finding was observed by Wan et al. (2006) with the growth of Leymus chinensis, a C3 grass species and Chloris virgate, a C4 grass in a mixed pot culture. The researchers cultivated L chinensis in a 21 cm-diameter pots with 2 individuals per pot (monoculture) or mixed with C. vir gate. Assimilation rate, quantum efficiency, light-saturated assimilation rate were then recorded for each set-up (Wan et al., 2006). Results revealed that interspecific competition significantly reduced the measured parameters for the C3 species. However, the presence of the C3 plants had no effect on the C4 species (Wan et al., 2006). The result suggested an asymmetric competition between a C3 and C4 species, with the negative effect taking its toll on the C3 plants only. Njambuya et al. (2011) also provided evidence in support of Wan et al. (2006) that indeed, asymmetric competition occurs. But Njambuya and her team discovered a significant finding: the response of the mixed culture of Lemna minuta, an invasive species and Lemna minor, a native species is also affected by the amount of nutrients supplemented into the culture. In the presence of high nutrient availability, the invasive species exhibited higher Relative Growth Rate (RGR) as compared to the native species (Njambuya et al., 2011) However, when under low nutrient conditions, the native species showed higher RGR relative to the invasive spec

How Ethnicity Essay Topics Can Be Defined

How Ethnicity Essay Topics Can Be DefinedEthnicity essay topics can range from social problems, to the history of the African American and Latino culture, to actual experiences with poverty, violence, racism, and an energy crisis. Because race and ethnicity are a dynamic field of study, it can be quite difficult to determine which academic requirements will most effectively represent a diverse student's life experience. In a diversity essay, ethnicity is represented by cultural heritage, ethnicity with English or Spanish as a second language, ethnicity through language, religion, and the environment, and so on.Essays should include a personal history of ethnicity, documenting how an individual identifies, how their ethnicity has been lived, and what they are experiencing in their lives. This can also reflect the general meaning of ethnic identity. The inclusion of life experiences should focus on daily life, negative experiences, and positive feelings about his or her ethnicity. Othe r parts of the essay can include what it was like to go to school with a variety of people of varying backgrounds, about the diversity of people within a certain race or ethnicity, how one's ethnicity has changed over time, what an ethnic identity means to him or her, and what an ethnic identity means to him or her.For example, if a student went to school with people of other races or ethnicities, but their ethnicity has changed over time, they might say, 'As a child, I went to school with all kinds of different kids of all kinds of different ethnicities and nationalities, but I am now more interested in speaking English than in hanging out with kids who look like me. Since I am now interested in speaking English, I've started to attend college to get my degree in English.' An ethnic identity can have a varied meaning to different people, as some people may mean the same thing by ethnic identity as others.This doesn't mean that the general case for ethnicity is not fair, it is fair, but the situation is complex. The general case is a lot like a street gang. They each have their own rules, behaviors, and symbols andif someone breaks any of them, they can threaten the victim, then there are consequences for the crime.When preparing to write an ethnic identity essay, there are many questions to ask yourself, such as, how much can a person know about his or her own ethnic background? How well does the individual understand his or her own background? Do the individuals of ethnic background have individual histories?Identity can also be defined by society. If a person of Mexican-American ethnicity knows that he or she is black, but knows that most people assume that he or she is white, then he or she may feel a sense of guilt. Identity is very complex and can change over time, but should be part of an ethnic identity, as discussed above.Ethnicity essay topics can be defined by social, intellectual, environmental, and other aspects of the individual's cultural herita ge. These other aspects can be about the individual's ethnic roots, their class, social status, etc. but the crucial point to remember is that one can identify with a group but not identify with the group.

"To develop successful innovation, a corporation should establish a conducive organizational climate. Traditional managers tend to adhere more strictly to establish hierarchical structures, to be less risk oriented, and to emphasize short terms results, all of which inhibit the creativity, flexibility, and risk required for new ventures. Organizations desiring an intrapreneurial climate need to encourage new ideas and experimental efforts, eliminating opportunity parameters, make resources available, promote a teamwork approach and voluntary intrapreneurship, and enlist top management's support."
