Kacie's+Third+Visit

Free Journal- For my free journal, I had decided to focus on the plant and animal life around and in Manoa Stream. Manoa Stream has a lot of the trees and plant life is abundant on one side of the stream compared to the other, which is lined with houses. I wonder if that is because one side is wilder and untamed plants making them just grow and grow and not be up kept while the other is more on the ‘domesticated’ side. I also noticed that there is a lot of ducks on one side of the stream compared to the other. They stay on the side with less vegetation, which doesn’t really make any sense to me because when researching, I had found that ducks tend to eat more of vegetation and insects. So I just didn’t understand why they would not rather stay on the side with more plants, which would ultimately lead to more bugs (because they would live near the plants). This lead me to think about how or do human disturbances have any effect on where the ducks live, because even though the one side has more vegetation, that is also the side in which more people are around, due to the trail and park right next to it. In my second visit I also noticed a strange white dove among all of the other ducks. I wonder if it was a sign of great natural selection, or maybe it just came from somewhere else, maybe there is a large population of white doves downstream. I wonder how the population would turn out if a white dove and regular duck mated and how that would affect all the future generations. Another question that came up, was how fit would this new generation of dove and duck be? I also notice that there are some very unusual fish that don’t seem native to the stream or even Hawaii. I don’t understand how they got into the stream but then again the stream is not a very secluded place, people could easily have access to it. Maybe it was like the wallaby incident in which people would put fish into the stream and then they ended up making their own specie in the stream or maybe it was a form of natural selection over years and generations. Another question that crossed my mind was how does the all the birds around the area obtain food? I was thinking that maybe it could be from the trees at the houses around the stream or from humans that go to the park. My last question was what would happen to the stream if all the vegetation left? What would the ducks and birds eat, because without any vegetation would they stay and possibly adapt or leave. If they leave then that would cause a huge domino effect on this ecosystem. Possibly causing a exponential growth rate within the fish population. We can only wait to see in the upcoming weeks how these questions will turn out.
