Ants on Guard


Ants protect the tangarana tree from being crowded out by other plants. In exchange, the ants live in hollow spaces in the branches.

I think this is interesting because the article actually relates to the title. But I mean this article was very well chosen. Also, is picture of the pitcher plant, the same pitcher plant that we saw at the arboretum? Because they sure did look the same, not I'm not sure.

I never new ants were so smart! The ones that live on the acacia trees were able to defend the plant, which allowed the plant to live. In return, the ants got food and drink from the plant. I wonder if the ants in the pitcher plant had some kind of oil on them that resisted the pitcher plant stuff. I think it was really cool how the spiders were able to escape the bodyguard ants attack by being still. Did the ants not see the spiders? Also, I found it hard to believe that something under half an inch long, some times only a millimeter long, can protect a tree from something the size of a bird or rat with strength in numbers.

I thought this article was really cool because I learned about a type of ant that I never knew existed! When someone says, "Ants!" I always think of red ants of black ants. No I can think of acacia ants! I would hate to get bitten by multiple ants, but discovering a new species of ant, would be really cool. I thought that it was really cool how the ants protect the plant, and the plant gives them shelter! Jaesan, to answer your question, the pitcher plant was the same type of plant that we saw at the arboretum. I really thought that this article was interesting, because unlike bees, these ants can sting multiple times. Theses tiny ant can protect a whole tree from larger things like spiders, birds, or rats. I find that really cool.

Were ants always considered an intellegent species. I mean these are things that are only 1/4 of an inch, that's extremely tiny. Acacia tree and the ants have only benefits. The ants eat food from the Acacia tree that would normaly be eaten. They benefit from being protected from other animals and trees. The animals are driven away becuase they know that touching the tree could cause pain, and even death. The ants benefit from unlimited food. I can't believe that these ants can make elephants and deer run off.
Ants also live with tangaranas, a type of tree. The ants promise not letting any other plants, which can be competition for the nutrients and water around in the ground. They also don't allow any other animals to live nearby.
I thought it was interesting that the spider can stay so still. I can't imagine how long it would take to make that adaptation. Also, how do ant manage to stay alive in the pitcher plant?
I found a couple of other mutualism relationships. For example, algea and the spider crab. The spider crab allows the algea to live on the crab's shell. The crab gets camoflauge and the algea gets a good place to live. Also, there's a certain type of bacteria that lives in the human's intestines. This bacteria eats the food that us humans can't digest. The bacteria gets food, and we can digest all our food. Lastly, I just want to point out that bee's and flower's have a mutualism relationship. The bee gets food from the nectar it collects, and the flower benefits becuase it is pollunated. In conclusion, I never knew how intellegent animals such as bee's, ant's, bacteria, and algea.

It was truly amazing to learn that ants, and even trees have "personalities"! I didn't even know they could think so much, and now I see them thinking hard, and putting their thoughts into actions like humans! These animals are so incredibly intelligent!

Madi said...

It was really interesting to learn that plants and animals can work together like that and I loved how the authors of the article made it easy for you to learn new termanology like "symbiosis" and "mutualism".

Madi said...

I really enjoyed this article because it explained something that was new and different, but I could still understand what was happening; it wasn't too weird. Also, they explained everything somewhat sophisticated-ly, but again, I was still able to understand everything the authors were trying to tell me. I'd give this article an 8/10.

Greta said...

I think that this article is very interesting because the ants have somehow managed to scare things like deer and elephants. It shows that numbers not size are what really count. I mean think of that question: would you rather be attacked by a 100 duck sized horses or 1 horse sized duck? I also think that it is cool that little ants that are about an inch can protect their home from larger things and even tough plants. One question though. How can a spider stay that still and how do the ants not notice it? Does the spider just camouflage into the tree bark? Or can the ants only see moving things?

Joel said...

I find this very interesting. It is truly amazing that these ants are smart enough to know that their home is the acadia tree. I have always found you could bulldoze an entire tree and the ants could not care less. Usually, the ants will stay in one spot for their entire lives and not do any defending of their habitats.

Sophia said...

When I started reading this article, I was extremely amazed. I didn't think that ants and acacia trees live in symbiosis, let alone mutualism. This is amazing because usually when you have a symbiosis, like the pitcher plant and the mosquito larva, it is a symbiosis where only one of the organisms benefits, but this isn't true in the ant and acacia tree symbiosis. It is also truly fascinating that the ants can tell if a seedling growing near or on their home tree is an acacia or not. This sense helps them know what plants to destroy and what plants not to destroy. Another amazing thing that I learned from this article is that some spiders have found a way to avoid being stung by the ants and being able to benefit from the ant and acacia tree symbiosis. This surprised me because I thought that nothing would be able to get past these ants in the beginning of the article, but know I understand that the spiders just sat still and by doing this avoided the ants stinging them.

I did not know that certain ants are poisonous. It was so interesting that such small creatures were so powerful and fearsome. Since we would often refer to ants as small powerless creatures. They are small but mighty. Many people call me small but mighty as well. So you do not want to mess the animals that are small and sometimes even cute because we can be vicious.

Charlotte said...

This article was very informative. I wonder if the orb spiders already knew about the plant or were born with common sense. Actually, Ally O., bees CAn sting multiple times. That's how they kill their prey. But since our skin has so many layers, the stinger gets stuck. Since the bee is trying to pull it's stinger out and is putting tremendous force on it, the bee looses the stinger and dies. Why? The stinger is connected to the bee's heart, so when it's gone, the bee dies. Back to the article. The acacia ants seem a lot like woodcutter ants to me, with the pinching mandables that spray poison. These ants are certainitaly exceptional, but I wouldn't call them "smart". First of all, they are simply relying on their plant for food and shelter. All they think (if they do that) when they're attacking things coming near is this: MY home. MY food. NOT YOURS. GO.
Although, it is pretty awesome that they can defeat things larger than them like birds and spiders. Also, based on the chemicals, they can even protect their tree from anything, including other plant life. Over all, the most intriging thing I found was that something that powerful could be in a package that small.

I thought the entire article as well as the video had some very interesting and surprising facts to share. Some of my favorites were the symbiosis relationship. I found it so interesting that a plant and an animal can have a "bartering" relationship with one another. I also had no idea that ants stung. That was a new fact that amplified my fear of ants to a maximum!

Christina said...

This article was fascinating! I liked it because the idea of ants being so strong is new.I thought that it was interesting that different kinds of ants can survive in different surroundings. I also had a question: Why do some of the ants live in the acacia, tangarana, and pitcher plant in particular? Are there more environments for living for ants that were just not mentioned in the article? If not, is there any reason why these plants make better homes than others? It surprises me that these ants are so intelligent and know that they have to protect their homes. I did some research, and multiple websites say that ants have the largest brains in proportion to their size in their family. I also have one last question. Why did the ants ignore the spider? Did they not see it, or do they realize that it is not threatening them or their home?

Bianca said...

I never thought or knew that ants could be so serious about their property. To me, ants were just tiny disgusting insects that, didn't mean anything because if you step on them, they'll die. However, this article clearly proved me wrong because you can see that ants are very smart, and can do many things despite their size. Now that I know what they can do, I really would not want to get stung by an acacia ant! I also thought that the experiments that the scientists did to find out the characteristics of the acacia ants were really cool and interesting. Something that fascinated me was that the pitcher plant was an ant plant. I remember looking at the pitcher plant at the arboretum, and when the article mentioned the plant, I was really surprised because I had no idea that it was an ant plant. I also never knew that the pitcher plant was in Borneo. A little off topic, but my primate the Orangutan lives in Borneo, so I found a connection there as well. Like Ben, I wonder if the ants saw the spiders or not. I wonder if they know that when they're walking around on the plant, that they're walking right past them, or crawling right over them. Do the ants think that if the spiders don't move, they won't attack their home? Even though I'm not too keen on insects, this article really amused me, and it was a lot of fun to read.

Morgan said...

Berfore I read this article I thought that ants were prety stupid. When I was yonger I would just step on ants and think nothing of it. Now however, I will try not to kill any more ants than I have to. I never knew ants were so smart, and that they could realize that if they did something for a plant, the plant would do something for them. However that brings up the question of how nice humans are. Most humans if you do something for them they will not usually return the favor. I still think that it is just amazing that something so small can fend off something as big as a bird.

Maddie W. said...

I think that it is really interesting that the ants can coexist with the tree. I did not know that it was posible for ants to kill of all animals and plants that it does not want. I also think that it is cool that if a spider is motionless on the tree the ants will leave it alone. I wonder if the ants don't even know that it is there. I think that it would be extremely hard to stay completely still while the ants were crawling all over me. I think that it is interesting how the ants can survive in the pitcher plant as well. I would think that the pitcher plant would not be able to control what it kills or does not kill. I wonder if it can control it, or if the ants just figure out a way to survive themselves.

I've heard of many living things protecting their property, but I have never known that ants are this protective of their "real estate." I found this article fascinating because I never knew some a lot of these things. I knew about mutualism and relationships between certain animals, but I never knew about these kind of relationships. I found it cool that the ants use the tree as their home and their food supply, and in return the tree gets protection from leave eating animals, and plants that may overgrow the tree and cut off its food supply. The pitcher plant relationship is also very fascinating as the pitcher plant allows the ants to grab some of the dead insects from the plant. In the meantime, the ants use the pitcher plant as their toilet and their trash can for leftovers so that the pitcher plant gets a lot of food. My favorite thing however is how the spiders manage to blend in by staying completely still, not to mention their escape plan is great. A few people asked this, but do the ants not attack the spiders because they recognize movement as an offense, they sense vibrations, they think they are part of the tree or something entirely different?

Sorry for posting the same comment twice. My computer accidentally posted two comments instead of one.

Brian said...

I thought that this article would just be a bunch of bogus information about how great ants are and etc. But then as i read more and more of the article, i realize that (as Ben said) that ants are really smart considering the size of their brains. I also found it cool that I could relate to the Pitcher plant as we saw it at the arboretum

Ali said...

When I was reading the article I was very interested in the acacia ants. I thought that it was very interesting that both the ants and the tree benefited from it. The ants had a food and shelter, while the tree had protection from any unwanted animals. Though the ants protected the acacia tree spiders were still able to live on the tree by staying still. What fascinated me the most is that the ants can even stop an elephant from coming near the ant. All they have to do is bite the elephant in the face. The acacia ant is a topic that I might continue to research.

Jonas said...

When I read this article, I realized that ants were pretty intelligent. It's very smart of them to travel through the rural area, finding these acacia trees. It totally makes sense how they use that as a home. Also, stinging to protect their territory. Not lots of animals out there that do that. Anyway, that was one of my favorite articles

Samantha said...

I really liked this article. I had no idea that ants and plants had such complicated mutualistic relationships. However, while reading this article, I came up with some topics I would like to research further. First, I want to explore and learn more about mutualistic relationships found between animals. In addition, I want to research other mutualistic relationships that exist between animals and plants. I also want to find out in which regions and environments mutualistic relationships are found.

Samantha said...

Earlier I mentioned a couple of topics that I wanted to pursue concerning mutualistic relationships, and the following is a summary of what I found. In my exploration into these unique relationships, I learned of two examples that stood out to me as very interesting. The first involves the relationship between an oxpecker bird and a zebra. Oxpecker birds land on zebras and pick parasites from their fur. They do this with their beaks, and eat the parasites. This relationship benefits both animals because the zebras get clean and the birds get a meal. The second example I found is between bees and flowers. This relationship is especially interesting because it deals with both animals and plants. Bees take the nectar from the flowers, and make it into food. This of course, helps the bee. This relationship also helps the flower, however, because the bees pollinate. In other words, in this relationship the bees are fed and the flowers can reproduce. As mentioned above, I also explored which regions and environments have these mutualistic relationships. And, the real answer is that they are found in many different environments all over the world. Even in the ocean, mutualistic relationships can be found. Wherever animals are living, they are finding ways to cope and survive Often this involves establishing helpful relationships with other animals.

I do understand where many are coming from (above), although I disagree with the fact that this is so shocking. Yes, they are quite intelligent, but I wouldn't overestimate that fact. They are just doing what any other animal on instinct would do, to protect their prized possessions or spouse (i.e. lions and cubs, honeybees and hives, etc.). Also, may I remind that symbiosis doesn't only occur between plants and ants.
