The Botany of Desire: Coevolution Blog





After reading Michael Pollan's The Botany of Desire, my perspective on our relationship with nature has changed. Replacing my traditional belief that humans are in control of their garden is the new idea that all every species is in charge. I choose the plants, I pull the weeds, I harvest the crops. This is the traditional idea of a human in a garden, where he alone is the subject. However, in reality these plants are manipulating humans into increasing numbers. Pollan focuses on apples, tulips, cannabis, and potatoes, and explores sweetness, beauty, intoxication, and control.

One very important relationship that exists in nature is the relationship between flowers and bees. The flower has actually manipulated the bee into moving its pollen from place to place. This is known as coevolution, because the flower increases its number by having its pollen moved from flower to flower, and the bee increases its number by have an abundant amount of hector to feed on. So while both parties are only looking after their won individual interests, they end up both helping each other.

The apple's sweetness is what attracts us, and bees, into eating it. Since we love the sweetness of the apple, we grow many apple trees. As a result, the number of apples increases, so the apple's plan succeeds.

Tulips make us do things because of there beauty. We have a desire to plant more tulips because we like to look at them. This is the intention of the tulip, and an important method for the growth of its numbers.

Cannabis attracts humans through its intoxication. As a result of this intoxication, humans want to grow as much cannabis as possible. Once again we see a plant's plan to increase its numbers.

An important question that Pollan asks is "Did I choose to plant these potatoes, or did the potato make me do it?". This is a question that Pollan asks throughout the who chapter. He makes the claim that both statements are indeed true. That we choose the potato because we want to eat it, and the potato entices us to choose it because it wants to be grown in the highest numbers possible. So while we may be remaking the potato to make it as large and tasteful as possible, the potato is remaking us, changing our way of life in a way that will cause us to grow more potatoes. The potatoes have manipulated us into moving and thinking for them

One human mistake is thinking of domesticated animal as less impressive than wild animals. For example, people think of wolves as a more impressive animal than domesticated dogs. However, in reality the dogs are more impressive because they have developed something that allows them to increase their numbers, which is being man's best friend. By doing this, dog population is more than 5 times greater than that of the wolves.

Pollan makes the valid argument that plants are more evolved than humans, despite humans displaying consciousness. Plants have invented photosynthesis, making them able to use the sun as a source of food. Humans on the other hand must grow food and harvest food. Also, plants have developed defense mechanisms, such as thorns and poisons, as well as developed chemical compounds that heal, and make humans want to use them.

In Charles Darwin's The Origin of Species, he first starts by talking about artificial selection, in which the humans select the most fit species, or at least in their eyes, to survive. However, he said that human desire plays the exact same role as nature, and that nature chooses the best fit species to survive.


http://www.divorcesaloon.com/2010/01/01/new-york-is-global-warming-behind-the-increasing-divorce-rate-around-the-world/

Pollan talks about how in a sense, everything is now domesticated, because humans have effected everywhere on earth by affecting the weather. He also says that humans are a part of nature as much as any other animal, and the idea that we have separated from nature is false.

Predator & Prey Population vs. Time


     Our goal in this experiment was to see how predator and prey populations changed over a course of many generations in a few different environments. Unfortunately, we did not have enough time to do more than one environmental situation. However, we can still analyze the data that we did get, and make a prediction for the data that we most likely would have gotten for the other locations.

Predator & Prey Population Line Graph



Analysis



Meadow

     For the meadow environment, we see that the Dark Green Rabbits continually had the highest population in every generation but one. This makes sense since the Dark Green Rabbits would have blended in the best to its surroundings, which were a dark green meadow. The fact that the Dark Green Rabbits became the most populated over time is due to natural selection, which states that a beneficial biological trait will become more common in a population, and a negative biological trait will become less common. In our experiment, both of the White Rabbits that migrated in to the meadow died within the first generation in which is migrated (the white rabbits that migrated to the meadow during generation 1 and 12 both died right away). This is because their trait of having white fur causes them to stick out in the dark green meadow, be spotted by wolves, and eaten. To the contrary, the dark green fur on the Dark Green Rabbits blended with the dark green meadow, causing them to become hard to spot, and less likely to be eaten. The Light Green Rabbits population was less than that of the Dark Green Rabbits, but more than that of the White Green Rabbits, because their light green fur made it harder for the wolves to spot them than to spot white fur, but easier for wolves to spot them compared to spotting dark green fur.

     As mentioned earlier, their was one generation in which the population of the Dark Green Rabbits was not the highest. In this generation, the 11th generation, the number of Wolves exceeded the number of not just the Dark Green Rabbits, but rather exceeded more than double the population of all of the three different colored rabbits combined. This certainly does not prove to be a favorable situation for the wolves, who need to eat 3 rabbits to survive and produce offspring. In the 11th generation, we see that all of the remaining rabbits were eaten by the wolves. This in effect caused all the wolves to die as well, because their were no longer any rabbits for them to eat. With all of the predators and prey dead, we had to wait for a new wolf and three new different colored rabbits to migrate into the meadow in order to form a 12th generation, which is the first generation that has no descendants from generation 1.

     Now that a new wolf and 3 rabbits migrated into the meadow and formed the 12th generation, a new population cycle occurs. Though it is a different cycle, you can see that the results are typically the same. The population of the Dark Green Rabbits increased at the highest rate, the Light Green Rabbits' population grew at a much slower rate, and the White Rabbits once again died off right away.

Snowy Area



http://wolfdreams.wordpress.com/2012/07/03/adrenal-dump/

     Though we did not actually perform this experiment, and therefore have no data, it can be predicted that the population of White Rabbits would increase at the highest rate, because their white fur would blend in with the white snow, and they would have a less likely chance of being eaten by the wolves (though the picture above shows a white rabbit being chased by a wolf, this would be the least likely rabbit to be hunted first, but would be the most hunted later because there will be so many of them, and so little of the other rabbits).

     If I had to make a hypothesis, I would predict that the Light Green Rabbits would be the most likely to go extinct immediately, because I think that the light green fur will be more visible to wolves than a dark green fur.




Light Green Environment


     If we had performed another experiment in an environment that is light green, I hypothesize that the population of the Light Green Rabbits would increase at the highest rate, the Dark Green Rabbits will increase population at a slow rate, and the White Rabbits will go extinct.






Conclusion


     Through this experiment, we saw several aspects of the predator-prey relationship in nature. The one thing that caught my eye, and that I have never thought of before, is that if the population of prey is really high, the predator population will increase rapidly, and in effect will cause both populations to rapidly decrease. This is because there will be so many wolves that the rabbit population will be nearly wiped out, and after the rabbit population is depleted, the wolves will starve and their population will too be depleted.

Volcano Eruption Affect on Temperate Forest



Natural Disasters occur all the time, though with different severities. Fires and earthquakes are events that occur daily, however ones with great impact are not as frequent. One of the most severe natural disaster is a volcanic eruption, which can destroy anything within miles from it. 


So what would happen to a Temperate Forest if a volcanic eruption occurred?


Well, animals are able to detect a volcanic eruption before they happens. They can sense changes in the land around them, and flee before being put in danger. Also, some plants, such as moss, can thrive near volcanos by extracting nutrients from the ash and cooled lava. Birds that can fly are good off, because they can migrate away from the increased temperature through migration.

Just the explosion of a volcano and the rocks that fall following the explosion would wipe out many plants and animals. Also, gases that it releases, such as hydrogen sulphide, hydrogen chloride, hydrogen fluoride, and carbon monoxide, all are poisonous to animals and will result in a large amount of deaths. There is also acid rain, which kills all vegetation and animals.

The lava from the volcano will destroy any plant or animal that it comes into contact with.


http://3enscience.wordpress.com/2010/04/27/volcanic-ash-eruption-in-icelandariffin’s/
http://geology.com/articles/volcanic-ash.shtml

All of the volcanic ash will form a thick cloud, making breathing for the animals nearly impossible. Then the ash falls to the floor of the forest will form a thick layer, covering all of the plants. This would kill the plants, because they can get no sunlight, and the animals, because they cannot eat the plants. The ash would also mix into the water and forms a material like concrete.

The factor that will cause the most loss of animal life will be the pyroclastic flow, which is when all of the hot gas and rock that is lifted by the eruption moves in a current away from the volcano at speeds of up to 450 mph and temperatures of up to 1800 degrees F. 

A lahar may also occur, which is a mudflow of rock debris that runs along a river. It can move very fast, wiping out anything in its way.

A volcanic eruption in a temperate forest could cause a wildfire, which could burn thousands of acres.

When the lava hardens, rock is formed, and the vegetation underneath has a hard time growing. However, this rock eventually becomes nice fertile soil.

Eruptions have been known to cause damage fore than 10 miles away.

Luckily, volcanic soil is very rich, so plants can return once the lava is cooled. It is likely that smaller animals would more likely survive, because smaller animals are better at dissipating heat. Also, any type of weed would be the first thing to grow back, because it doesn't need much to grow.
