Ecology/Species Lab

As humans we are constantly trying to improve our surroundings with golf courses, trails, and parks. While it is hard to find a reason not to have a park where everyone can go and enjoy some outdoor recreational activities, when humans add parks to the neighborhood they are changing the ecology of that environment. In many cases this will have unforeseen consequences to the near by humans.

Here is a photo of greenlake park, while this recreational area may look very inviting with a nice balance of nature and human interaction, be cautious all is not well.
In this photo you can see the adverse effects which the city planners did not take into account when building green lake park. The park is a safe heaven for a variety of conspicuous trouble makers. One of these trouble makers is responsible for this treachery and many other forms of misdeeds. BIRD SHIT!!
Suspect number one, the canada goose/ducks
Canada goose: Here in Seattle at the park I live very close to there are quite often large numbers of geese in the area. And they may be responsible for defecating on my
motorcycle.
Kingdom: Animalia
Species name: Branta canadensis
Common Name: Canada goose
Relationship: Well the geese pretty much just fly around and crap all over every thing eat all the grass on yards and then leave when they want. For me personally they do not hold any positive impacts except fun to look at and feed, and I have to wash my bike many more times then I would like. As a species interacting with humans they are mostly an annoyance especially at golf courses, crops, and people yards, so for most of us the relationship is commensal, the geese benefit from our parks and recreation because they have places to get food and bath in water without being hunted, but they do not really harm us in the long term. For some however who still like to hunt geese there is a predation influence that does have positive benefits for humans, if you like the taste of geese.
I don’t see much future changes in the relationship we have with geese whether it be predation or commensal.

Crow: The crow is my second culprit in the mystery of which bird is crapping on my sport bike, and the crow is a very likely suspect.
Kingdom: Animalia
Common name: American crow
Scientific name: Corvus brachyrhynchos
Relationship: From what I have found on the class websites the crow really does not do much for the human population. The crow is know to eat almost anything it finds including crops, road kill, other small birds, nuts, garbage, really anything. In farming communities crows were thought to be very damaging to crops, but recently it is suggested that the impact is countered by the fact they eat a lot of insects which could be more harmful then the birds themselves. For me they are loud noisy and when a few of them are sitting on power lines making noise as you walk by it’s a little freaky, and of course they may be the bird which owes me at least 2 dollars a month in car washing fees. I would list the crow as a commensal, with the crow being the benificiery of human habitat and humans not really getting anything from the birds.
Since the crow is a scavenger and eats anything I don’t seem them being effected by any type of environmental change, they seem to be very well adapted to any situation for survival and probably will never go away.

Pigeon: The last bird which I suspect of taking a dump on my bike is the pigeon. I have had to clean pigeon guano of my vehicles on many occasion, however where I live I think they may not be the responsible party only because the crows with there large territorial nature seem to keep them away except at the park
Kingdom: Animalia
Family: Columbidae
Common name: Common pigeon
Scientific name: Columba livia
Relationship: The pigeon for the most part is a scavenger as well eating just about any crap it finds. The pigeon feces can cause human illness and they pretty much crap on anything indiscrimenatly. I have read that there are individuals who do eat pigeons and there eggs. In previous wars pigeons were used to send messages as well as a food source, but for my interaction with them they don’t do much. So I will say our relationship is commensal with the pigeon getting the best of the deal and except for illness they can cause which I don’t think I have ever gotten they are not very harmful, unless you have crops and such.
Like crows, pigeons are very adaptive to different environments, cities, parks, rural areas, and they adapt well and breed easily, I don’t see humans relationship with them changing anytime soon.
Beer: My relationship with beer is a very rewarding one, especially if I drink just in moderation. Since I enjoy a good beer with dinner on many occasion this makes me greatly appreciate the main ingredients in beer, hops, wheat, and barley. So the next few species of plants I am going to cover are related to beer and I have a commensal relationship with all three. I also expect this relationship to continue long into the future, though the present growing food shortage and raising gas prices are making it more expensive to perchuse.

Wheat: In wheat beer wheat is used as the majority ingredient and provides a very smooth distinct flavor and aroma. Many wheat beers are top fermented and have some other flavorful ingredients added like banana and cloves.
Kingdom: Plantae
Scientific name: Triticum spp

Barley: The basic cereal grain which is a primary ingredient in making beer. There are three different types of barley used. The seeds grow in two, four, or six rows along the central stem.
Familly: Poaceae
Scientific name: Hordeum vulgare

Hops: Are a flower from a vine which has preservatives that add the essential oils for flavoring. There are bittering hops and there are aroma hops to balance the taste of beer depending on the type of beer you are making.
Scientific name: humulus lupullus

Yeast: Yeast is a unicellular fungi which is essential to brewing beer. Yeast is used to convert the sugars in the wort into alcohol.
Genus: Saccharomyces cerevisiae

Rooster: This is a picture of two of the roosters next to the house I am renting, I see them almost everyday as I walk by
Kingdom: Animalia
Common Name: red junglefowl
Scientific Name: Gallus gallus
Relationship: The rooster along with there breeding into domesticated chickens supply humans with food either from the eggs they lay or from eating the chicken itself.
At first I would say the relationship the rooster/chicken has with humans is symbiotic, we use them in a variety of ways as domesticated animals and there feathers are also used multitudes. In return we provide them with protection from predators and keep them healthy and well fed. The more I thought about the relationship it is also Predation since we as humans eat chickens or there eggs every day.
I think there will always be a strong relationship between humans and chickens as domesticated and wild animals. However this relationship can cause us harm when the chickens we eat catch deadly viruses it is easy for the viruses to spread and then affect the human population.

Wild Cat: Here is a picture of a cat in the neighborhood which the next door neighbors feed but they say the cat will not let them get close, so it is not a pet cat though the term wild cat seems to be senonomas with domesticated cats as well.
Kingdom: Animalia
Common Name: Wild Cat
Scientific Name: Felis silvestris
Relationship: As the powerpoint and text have pointed out the relationship humans have with cats may depend on what part of the world you live in. Here in the states I almost have to go with commensal. My reason is the cat as a domesticated animal gets a lot of benefit and with the one single exception of being cute and furry does not really provide any sustainable benefit for humans (you just play with them). We as humans feed them, give them medical help, and keep them safe for really very little return, of course cat lovers will argue this point. In other parts of the country however they are eaten so then the relationship is more predation, we as humans get more benefit because as we take care of them we also eat them, I personally will never want to eat a cat……
I expect this relationship of cats really getting the best of the evolutionary deal to continue for the distant future.
Grass: I used the word grass to describe the grass I find at the park, but the term is generic and does include many varieties of grass including bamboo. As you can see in the picture my grass is from the park and is recreational in purpose.
Familly: Gramineae (Poaceae
Scientific name: disambiguation
Relationship: We as humans have a very good relationship with grass as the generic term. Grass provides us many uses such as food for cattle, grains, and lawns for recreational use. We as humans in return take care of laws by fertilizing, cutting, and planting new laws, so it’s a mutually beneficial symbiotic relationship.

Camellia tree: Is an evergreen tree and stays green all year long, though it only blooms twice a year.
Kingdom: Plantae
Scientific name: Camellia sasanqua
Relationship: humans use the oils from the camellia tree for a variety of different applications, one of which helps to keep other insects out of the house and as an ingredient in insecticide. The tree needs lots of water but far to much for a person to actively water the tree, so humans use the oils from the trees and really on prune the tree and protect it, I would say the relationship would be commensal with us as humans getting the bigger benefit but not harming the trees themselves.

Dandelion: Are weeds which are generally considered a nuisance by most people. Weeds can be harmful to other native plants in your garden and can spread very quickly to become dominant. I would have to do more research to see if there are any benefits dandelions have for humans, but as of now I have to go and weed the lawn which is a pain so I am going to label them as parasitic in nature.
Kingdom: Plantae
Scientific name: Disambiguation
Genus: TaraxacumI do not see any change in the relationship humans have with dandelions, we try to kill them by weeding or chemically and they just keep growing back at will.

Salmon: One of my favorite foods for dinner. Fish in general are very healthy for you and in my opinion taste better then most prepared meats. While hamburgers have a lot of fats and cholesterol, fish has far less making it much healthier.
Family: Salmonidae
Common name: Atlantic salmon
Scientific name: Salmo salar
Relationship: In general I would have to say the relationship is parasitic, we humans eat salmon and fish them and in return we really don’t do much for them. If there were no humans left to eat fish and they only had natural predators they would thrive. Humans are also very damaging to the salmons natural habitat which is hurting the salmon population as well.
Aurochs: This is the more scientific name for the general name of cow which we use for milk and food as cattle. I do like a good hamburger on occasion but since taking this class I have tried to cut back on my meat intake. My personal experience I either drink or eat a product derived from the aurochs at least 3-4 times a week.
Common name: Cow, Milk Cow, Cattle
Scientific name: Bos Taurus
Relationship: I would have to say maybe the cow falls into the mutualism category, because while we eat them and drink their milk we as humans do also provide them protection from predators, food, and medical care. The ones we use for milk live long lives, though animal rights persons will probably have a comment or two on that subject as well. So while it might seem like we humans take a big advantage from the cows we have in the long run the cow is able to prosper and be safe, until we want a hamburger.
I do not imagine the relationship we have with cows currently is going to change dramatically during my lifetime, it seems like a good working relationship now and why change a good thing.

Tomato: I eat tomatoes in sandwiches, burritos, on salads and in other ways a few times a week. The tomato is easily my favorite vegetable to eat, and I am even considering growing a few tomato plants in the future.
Scientific name: Solanum lycopersicum
Kingdom: Plantae
Relationship: I see the tomato plant and humans working well together as a symbiotic relationship where we help the plant by cultivating, and feed them, and in return we as humans eat the fruit of there labor. Since tomatoes are very easy to grow and can prosper in a variety of environmental conditions the tomato is a good crop and we will continue to use it.

Avocado: Also one of my favorite fruits to eat, I use avocado’s for salads, sandwiches and at work just eating one with a little salt as a snack.
Familly: Lauraceae
Scientific name: Persea americana
Relationship: Very similar to the tomato plant, we as humans use the avocado tree to get its fruit and in return the tree is allowed to thrive and grow. So like the tomato plant either symbiotic or commensal, since we eat the fruit but do not really harm the tree itself.
E. Coli
Scientific name: Escherichia coli
Domain: Bacteria
Phylum: Proteobacteria
E.coli are bacteria which are constantly inhabiting the body, mostly in the lower intestines. As with the majority of bacteria in our body E. Coli is generally harmless unless you get certain strains which can cause the body harm. Serotype is a E. coli bacteria which can cause food poising. The strains of E. coli which are of benefit produce vitamin k2 which is beneficial to the body.
Relationship: The normal good strains of E. coli would have a commensal, since humans provide a place for bacteria to live but they do not do us any real harm. The bad bacteria of course have a different relationship with us, more like parasitic in nature. As a human we will always have bacteria in us no matter what we do they are a part of our body.

Common name: Plaque (can be plaque as one example)
Scientific name: Actinomyces
Phylum: Actinobacteria
Actinomyces is an opportunistic bacteria which can cause illness in humans and other animals. Generally actinomyces is found in the mouth but can also be found in the colon. Actinomyces also helps with the decomposition of topsoil and organic plant life. The disease actinomyces can cause are normally in the oral cavity but some species can affect the lungs or gastrointestinal tract. These bacteria are definetaly in the parasitic department and many of us have probably felt there effects and not even known it. Since these bacteria are microscopic I don’t think there relationship with humans is going to change ever.

Body odor: We as humans have all experienced body odor and after taking this course I now know what actually causes body odor. Some bacteria are not bad for the body as I have disgused but when you sweat or get warm these microscopic bacteria multiply quite rapidly and thus start to produce the smell. Natural body odor has a very faint smell and is almost considered odorless, its when you have an increase in bacteria that the smell can be overpowering.
Scientific name: bromhidrosis, bromidrosis, osmidrosis, and ozochrotia
Domain: Bacteria (pathogenic bacteris)
Relationship: Again as with most of the bacteria I have listed the one responsible for body odor is parasitic and since as humans we are always going to sweat, and depending on how hard the body is working, sweat a lot, these bacteria will always be there ready to multiply.

Scientific name: Lactobacillus
Kingdom: Bacteria
One type of species: Lactobacillus acetotolerans
These bacteria are very helpful to the body and basically they help to convert milk in the digestive system which is lactose into sugars and lactic acid. In humans these helpful bacteria are symbiotic and contribute to the gut flora (term for helpful bacteria). Are relationship with these bacteria is very good and it is in humans best interest to keep the on our good side, or in our good side I should say.

Quick Refrence of terms:
Symbiotic = Mutually beneficial, both species benefit.
Parasitic = One species benefits (parasite) and the other is harmed (host)
Commensal = One species benefits, the other is unharmed
Mutualism = Both species benefit, like symbiosis, but it may one species may seem to have a bigger advantage however in the long run they will both benefit.
Predation = A version of parasitic, one species is the predator, however the other species can still be viewed as having a benefit like in mutualistic.
