Transcript

  1. Riparian Zone Retreat and population studies Jacob Grace, Honors Biology II, Pd 1.
  2.  
  3. Niche of Bald Eagle Scientific Name Haliaetus leucocephalus <ul><li>Bald eagles prefer habitats close to seacoast or even other water bodies such as lakes. </li></ul><ul><li>They usually depend on fish and other animals that may live never water. Nothing really depends on it for food due to that they are very large birds and are not really killable by other animals. </li></ul><ul><li>The hunting area or home range patrolled by a bald eagle varies from 1700 to 10000 acres. Home ranges are smaller where food is present in great quantity. They usually hunt during the day and they will hunt fish and small game. </li></ul>
  4. Factors which Affect Birth Rate of Bald Eagle <ul><li>It varies from all of the different regions that the animal lives. But in the south they will usually mate from September through November. </li></ul><ul><li>They will often reproduce once a year. </li></ul><ul><li>There gestation period is usually around 35 days. </li></ul><ul><li>They will often lay two eggs every time. </li></ul><ul><li>They will nurture the babies till they are old enough to fly and care for themselves </li></ul><ul><li>They usually start when they are 4-6 years old and stop when they die </li></ul>
  5. Factors Which Affect the Death Rate of Bald Eagle <ul><li>The bald eagle is usually part of predator prey interactions. It is usually the predator due to the enormous size of the bird. It usually attacks small game and fish. </li></ul><ul><li>They can live in the wild for upwards of 30 years in the wild </li></ul><ul><li>There are really no common parasites that will harm the bald eagle. There are some rare cases where a parasite will harm the egg or hatchling but these type or not deathly. </li></ul><ul><li>There is no overpopulation due to that there has been a small population and a real decrease in them. But over the last few years there has been an uproar in the bald eagle population. </li></ul>
  6. Food Chain of Bald Eagle Producer Autotroph Primary Consumer Omnivore Secondary Consumer Carnivore Third Consumer Carnivore
  7. Food web of bald Eagle Herbivore Producer Omnivore Carnivore Carnivore Producer Carnivore Herbivore Herbivore Omnivore Producer
  8. Population Sampling Techniques <ul><li>There are various ways that they sample the population. One way is to catch a number of the animal and then to mark them and catch them again and you can use the numbers to get a population sample. </li></ul><ul><li>The way that they get the population size of the bald eagle is to basically catch and release the animals due to that they were an endangered species at one time. </li></ul>
  9. Stream Quality Data & Analysis <ul><li>The graph shows that the stream had a very good stream quality due the high number of class one organisms. </li></ul><ul><li>The more organisms in class one and class two show good stream, any in three describe bad quality. </li></ul><ul><li>It is good because my animal usually eats some sort of fish so they would want to fish in a good quality stream. </li></ul><ul><li>I t would be affected highly because they usually eat a lot of the fish that live in streams. </li></ul>
  10. Water Testing Data & Analysis <ul><li>You want a ph that is around 7 and dissolved oxygen to be around 10 and every thing else should be a very low number. </li></ul><ul><li>The ideal range is 6.5 to 7.5 for ph, a 10 or so for dissolved oxygen and very low to a trace of nitrates or phosphates. </li></ul><ul><li>It is going to be a lot harder life if they would live around the marsh or mine. Due to that there is going to be a very low amount of fish if any in those types of streams. </li></ul><ul><li>You want to also have a very turbidity and the temp should also be low because it can hold more oxygen when its cold. </li></ul>
  11. Soil Testing & Analysis <ul><li>The levels in the soil are very important to the plants. If they are not at the right levels that they should be they are going to die or not be able to grow. </li></ul><ul><li>The ideal range for ph is 6.5 to 7.5, the next three chemicals should be present but in smaller amounts. </li></ul><ul><li>If the numbers are out of the ideal ranges they are going to kill the plants and the plants are crucial to the quality of the stream. </li></ul>
  12. Positive and Negative Factors <ul><li>The stream would be a very good match to my animal. But the acid mine stream and the marsh would be a negative due to the limited number of fish present in the stream. </li></ul><ul><li>The soil conditions are not as big but they would need the trees and such to live in. So the plants are not able to grow they are not going to have any protection or shelter. </li></ul><ul><li>Some of the factors that are negatively effecting the riparian zone are the golf courses and the farms. By putting all the fertilizers down they are effecting the streams and the soil. Some of the positive factors would be Powdermill and other places that take care of the streams. They are making sure that the organisms can survive in the streams. </li></ul>
  13. Conclusion <ul><li>Something new that I learned about the ecosystem would have to be large of amount of organisms that survive only in good water condition and the animals that only survive in low stream quality. </li></ul><ul><li>Some of the stuff that I found interesting would have to be all the different kinds of organisms that we caught when we were at Powdermill. </li></ul><ul><li>One topic that I would like research more would have to be the effect that golf courses have on the local riparian zone. </li></ul>
