Competition Of Chlamydomonas and Blue-Green Algae For Resources In The Campus Lake General Research Question: Will competition affect resources available in the Campus Lake? Population Ecology Experiment Null Hypothesis: The presence of Blue-Green Algae will not have an effect on the Chlamydomonas population. Alternative Hypothesis: The presence of Blue-Green Algae will have an effect on the Chlamydomonas population. Community Ecology Experiment Null Hypothesis: Nitrate concentration will not have an effect on chlorophyll levels in the Campus Lake. Alternative Hypothesis: Nitrate concentration will have an effect on chlorophyll levels in the Campus Lake. Methods Population Experiment First, nine test tubes were obtained. One test tube…

Since the 19th century, populations of white-tailed deer (Odocoileus virginianus), have been steadily increasing. This increase in population has caused many people to consider various ways to keep the deer populations in control (Brown et al. 2000). Despite record harvest rates and many unrestricted hunting laws, white-tailed deer are very abundant in many regions of the United States (Rawinski 2008). For example, the range of the white-tailed deer has expanded to include offshore islands,…

of the same problems. One major problem both cities have is their populations. Both cities have large populations and continue to grow. Beijing is seen as the more modern global city with huge technology and financial industries; additionally it is the capital of China. Mumbai is developing into a global city and will become quite important in the future as it has an emerging market and dominates India in many sectors. One thing that sets Mumbai apart from other emerging global cities is what it…

In conservation biology, it is one of the main goals to determine MVP (minimum viable population) and reserve size. These estimates that are produced via simulation, are valuable in the sense as grizzly populations are often endangered or threatened, and their population has been declining for a number of years (Wielgus, 2001). Although the population is declining, it is still legal in North America to hunt these endangered species, as trophy hunting and is believed to be beneficial or…

America and Nigeria and two entirely different countries. America is a developed country, who has one of the best economies in the world. Nigeria is a developing country who has one of the fastest growing populations in the world. Even though America and Nigeria are almost different of countries, they both face problems in their populations, urban patterns, and globalization. Both Nigeria and America have fast growing populations, but for two different reasons. While Nigeria faces the problems…

Introduction Are we too big? Can we cope with up to 38 million people? Good Morning Tony Abbott and ministers, in the next seven or so minutes, three new babies will be born, two people will pass away, and six people will migrate to Australia. Australia is experiencing a large population boom which can effect our economic prosperity, livability and environmental sustainability. If however managed adequately a growing population’s impacts can be reduced and possibly eliminated, thus providing a…

Population Dynamic Lab Report Purpose: Analyze graphs to determine the population size of two marine species. Explain how predation, birth, and death rates impact marine populations. Describe how biotic and abiotic factors influence marine populations. Research: 1. Prey Initial Size: The starting number of prey. (Assume that the seals have an unlimited amount of food.) 2. Prey Growth Rate: The birth rate of the prey. The larger the growth rate, the faster the prey population will increase.…

by Matt Rosenberg, between 2010 and 2015, the crude birth rate, defined as the amount of births for 1,000 people, was 19.4. The crude death rate, on the other hand, was 8.1. With the birth rate being over twice as fast as the death rate, it is indeed possible that overpopulation will occur, and the amount of land provided by Earth will be insufficient to house all of its inhabitants. Since most people that live on Earth already are uninfluential on social media, especially the 5.165 billion…

the world was creating new technologies that enhanced the farmers crops, which spiked the population size. Disease was more common in civilizations than it was previously because of the increase population density (Chiras, D. D., 2016). Chemicals are used on crops, which can hurt the soil, air, and animal population around the agriculture. Some of the biggest reasons that this type of society hurts that environment is because of poor agriculture, overgrazing, and excessive timber cutting…

hypothesis that the bubble population without help would have a type III survivorship curve was rejected because the survivorship curve of this population resembled a type II curve. It likely resembled this type of survivorship curve because the population was likely to die at any point in time, since there were no factors to inhibit or encourage the bubbles to pop, but once they hit the ground or any other obstacle, which could have happened randomly at any point in time, they popped. This…
