Photos: The Holy Grail of Preservation

The final unit of our Population class we discussed and learned about how populations grow and change. We took a trip to the Peggy Notebaert Nature Museum to view the change of population among butterflies along with seeing the change of Chicago from a nature preserve. For our last unit we created a very short and small one day action project that focused on methods of preservation. I decided to write a short essay about photography and what it has done for us in terms of preservation. I hope you enjoy; thank you. 

Photography has been around for a long time without a doubt; with the oldest camera being made in the 1500s. This camera was called the Camera Obscura and was the first pinhole camera. This camera would let in a small amounts of light through a small hole in a very dark area. The image would be projected onto the wall and would be traced out with pencils or paint. Photographs and pictures are a simple way of preserving the look of something; they are a visual time stamp.

In the image below we are clearly able to see what it's attempting to show. Photography is great for preserving the specific look of a thing compared to a written description. If someone were to write about the look of the yellow flower it would probably take a long time to get all the specifics of the flower. Taking a photograph is a much simpler way obtaining the the look of something with detail and precision. A picture is worth one thousand words. Without photographs, many people wouldn’t know what a polar bear looked like.

Photography is a very useful tool as a preservation method. Photography can help scientists get an accurate description of an organism's physical traits, the habitat it lives in, and the organism’s resources. Drawing works the same as photography but it’s less efficient and can’t gather specifics and dimensions like photos can. A still photo for the most pat can’t be wrong with the the dimensions of a thing, drawing can be inconsistent and the look could be changed due to human error. Sight is one of the most useful traits for some organisms; making photographs very helpful for seeing something that is potentially dangerous without actually going face to face with it. Photography has helped us preserve the look and the behavior of organisms for a very long time.

Chil Flamingo: A New Threat

In the second unit of our Population class, we learned, practiced, and discussed several math concepts from finding standard deviation to mean, median, and mode to combination/permutation. We also learned a lot about our animals and evolution. Evolution was another really big focus of this unit. We discussed how evolution happens, what and why specific traits stay, and how that effects a species. I really enjoyed this unit because it went deep into evolution and made sure I got a good grasp of the content in this unit. For this action project, I created a presentation and predicted and hypothesized what could happen if a predator was to move into the Chilean Flamingo's habitat. I hope you enjoy the learning about what traits would work well for flamingos with a different predator.

Math Concepts

I assumed the height of my different flamingos and put them into a list so I can measure how far our outlier are from the center. The average height of a Chilean flamingo 43.2 in -51.6 in

Mean- 47.27      Median- 48        Mode- 48      Range- 9.59     Maximum- 51.6

Minimum- 42      1Q- 44.4           3Q- 49.5 


1. John- 48 in 
2. Carla- 49.2 in
3. Hubert- 44.4 in  
4. Robert- 46.8 in 
5. Leah- 48 in 
6. Michael- 42 in 
7. Max- 43.2 in
8. Ethan- 50 in 
9. Joseph- 51.6 in 

Standard deviation 

The standard deviation of the data tells us what percentage of the flamingos are in a certain height range.
Mean = 47.27
S= 3.13 

IF "Standard Deviation" 2017

68% of the flamingos = 44.14 in - 50. 4 in
95% of the flamingos = 41.01 in- 53.53 in
99% of the flamingos = 37.88 in- 56.66 in

This picture shows that the 99% of the 9 flamingos we chose land in between the heights of 37.88 inches and 56.66 inches. 95% of the 9 flamingos are between the heights of 41.01 inches and 53.53 inches. 68% of the 9 flamingos land between 44.14 inches and 50.4 inches in height.

Combination and permutation

For finding the combination, I found that introducing the flamingos into a new environment doesn't matter; making the situation a combination. Shown in the photo below is the work that I did to find the permutation and combination of my set. Their are 9 animals in my set making the "n" = 9. I chose three flamingos to possibly survive making my "r" = 3.

A Chil Flamingo

In this first unit of our new class Population, we focused on creating an art piece of an organism of choice. Our class visited Lincoln Park Zoo to view our organisms. I really enjoyed seeing multiple Chilean flamingos together; I was able to see how they communicated and expressed themselves as well as their physical traits. I gathered photos of the flamingos to examine and view their morphological characteristics that put them in their taxonomic levels. I also created an art piece of the Chilean flamingo to show of where these taxonomic traits are on the flamingos. I really enjoyed this first unit, especially when we learned about set theory and how that correlates to the organisms being placed in categories. I hope you enjoy learning about his interesting first unit.

Taxonomy
First, I created a table to specify the taxonomy of a Phoenicopteriformes chilensis (Chilean flamingo). You will notice that the Genus and species have the same taxonomic description because a Chilean flamingo is the only animal within its genus.


Taxonomic classifications
Taxonomic level
Taxonomic description
Kingdom
Animalia
Sexual reproduction, eukaryotic, multi-cellular.
Phylum
Chordata
Has a spinal cord.
Class
Aves
Toothless beaked birds, hard laid eggs, feathers
Order
Phoenicopteriformes
Long legged, stout bills
Family
Phoenicopteridae
Dipped bill, water wading capabilities
Genus
Phoenicopterus
A specific dipped shape to their bill
Species
Phoenicopteriformes chilinsis
Originating from Chile, can reproduce offspring that is also capable of having offspring

Taxonomy Art Piece
The next step was to create an art piece that would show where the  specific taxonomy traits were being shown off. I decided to draw a Chilean flamingo. The taxonomy traits and where they are located are shown off in the image below.

Venn diagram Comparisons 
Next I created a Venn-diagram to show off the likeness and differences between the animal that I chose versus animals that my classmates chose. One of my classmates chose to do research on a Fennec Fox, while another did research on polar bears. Feel free to view their blogs afterwards. While creating this Venn-diagram I found that its pretty difficult to find similarities between Chilean Flamingos and Polar bears and Fennec Foxes, mainly because two are mammals while the other is a type of bird. This is good information, we want to truly show off how unique these animals are.

Set Theory 
Then, I created a set of set theory statements that describe the relations between Chilean flamingos and the bird's taxonomic traits.

F(traits of flamingos)= {can fly, bill, two legs, lives in flocks, pink}      
B(traits of birds)= {wings, teeth-less, hard eggs, endothermic, feathers}

1. F∩B = {feathers, hard eggs, wings, endothermic, teeth-less}
2. {feathers, hard eggs, teeth-less} ∈ F
3. {beak, herbivore, lives singular, green, mammal} ⊂' F
4. F⊂B
5. F∪B = {feathers, wings, teeth-less, endothermic, hard eggs, two legs, pink, lives in flocks, bill, can fly}

Photography
I also managed to snap a photo of a Chilean Flamingo at Lincoln Park Zoo. I used this photo a reference for my art piece. I gathered some interesting information about how Chilean flamingos live and interact. I found that Chilean flamingos are pink because of a natural pink dye called canthaxantin is in their diet of shrimp and blue-green algae. Wild Chilean flamingos also live in massive groups where they feast on shrimp. Flamingos are essentially defenseless against other larger creatures, so they live in very larger groups:400 flamingos are way more intimidating than 20.

AP conclusive
Overall this unit was very enjoyable, I thought going to Lincoln park zoo was a pretty necessary FE for me and the class. There wasn't anything in this unit that I didn't like, The workload felt perfect an the unit went at the perfect pace for me. We got a lot of time to work on this action project, and a lot of time to complete our work and get a good grasp of the content in the class. I'm happy with how my action project turned out. I was able to take some great picture of Chilean flamingos and learn some new information about them. I didn't really struggle with this action project too much because I was able to understand the topic and concepts pretty efficiently. Thanks for viewing this blog and feel free to check out my classmates research on animals.
