Spotlight on Students: Primate Conservation

The following is a guest post featuring the work of students enrolled in my Anth 102 courses.  These students are highlighting the importance of primate conservation and featuring specific primates that are currently endangered.  I hope you find these pieces informative and are inspired to make a positive change in the world that will help these and other endangered primates.

Blue-eyed black lemur baby


            There are several endangered species in the world today. Many of these species are endangered either directly or indirectly by humans. Often times if humans would cease the behavior contributing to the demise of a species then the species might have a better chance of making a comeback. All species have a place and a role on Earth so we should work hard to save every one of them. Eulemur flavirons, also known as the blue-eyed black lemur or Sclaters lemur is a stunning creature. Unfortunately, according to the International Union for Conversation of Nature (IUCN) the blue-eyed black lemur is considered critically endangered. Critically endangered means that there is a high risk of the species disappearing and becoming extinct in the wild. In 2013 the IUCN reported that this lemur has been critically endangered since 1996 and before that it had been considered endangered since 1986. The population of the blue-eyed black lemurs continues to dwindle (IUCN).

            The blue-eyed black lemur is one of only two primates besides humans that have blue eyes (Philadelphia). Blue-eyed black lemurs are sexually dichromatic, meaning that the males and females look different (Duke).  The fur of the males is all black. The fur of the female can range from brown to gray. The females of this species are dominant to the males and the lemurs live in large groups consisting of males, females, and young (Racine). The blue-eyed black lemurs are mostly frugivores and folivores, meaning that their diet consists of fruit, leaves, plants, flowers, and occasionally insects or very small animals (Duke).  Blue-eyed black lemurs in the wild can only be found in the Sambirano region of northwest of Madagascar, living in the trees (IUCN).

            Humans are partially responsible for the blue-eyed black lemur being endangered. Humans have been cutting down the trees and using a technique called slash and burn to clear the  land lemurs use as their habitat in order to use it for farming (IUCN). Humans are also endangering the blue-eyed black lemurs through hunting and trapping (Duke). The lemurs that are hunted or trapped are used for food or occasionally to keep the animal as a pet (Taylor).

            The blue-eyed black lemur is almost always on the top ten list of endangered lemurs. According to the Duke Lemur Center it is difficult to get an accurate count, but it is possible that there are no more than 1000 blue-eyed black lemurs in the wild. There are currently some efforts being made to try to protect the blue-eyed black lemur. In the Befotaka region of Madagascar there is a proposed reserve area in order to attempt to help protect the lemur, but nothing has been made official or legal as of yet (Duke). If we could actually get this reserve up and running and protecting the lemurs in their natural environment then they might have a better chance to get their numbers back up. There are some zoos that are trying and successfully breeding the blue-eyed black lemur. Last year a baby was born at the Mulhouse Zoo and Botanical Park in France (Taylor).

            It is important that we keep the blue-eyed black lemur for a couple of reasons. One of the main reasons to prevent the extinction of these animals is because many species of lemurs are endangered and they generally live in different areas. The lemurs play a role in the ecosystem with their diets. By spreading seeds from the fruits they eat and also with pollination. When a lemur eats a flower, they get the flowers pollen on their fur and carry it along to the next flower.  By doing this they help to keep the plants in their habitat reproducing. Blue-eyed black lemurs are also part of the food chain and are a food source for other wild life. If they were to disappear, their loss would impact the rest of the ecosystem. 

            Every primate species needs to be saved from extinction for the same reasons that the blue-eyed lemur needs to be saved from extinction. When a species becomes extinct, their habitat is altered by the loss of it living there. The food chain is disrupted, causing either the predator of that species to have a hard time or another species becoming the new prey. Humans also then turn to another species to meet the needs that the extinct species previously met.

            The blue-eyed black lemur is just one of many primates that are critically endangered today. We need to save all endangered primates, especially the ones that we are directly responsible for endangering. We also need to stop causing other animals and plant species from becoming endangered, continuing the cycle of endangering certain species.

Anthropology 102: 1001

            Many primate species are endangered all over the world. The main cause behind the endangerment of these species is generally due to human activity. Like all organisms, all primates play key roles in their ecosystems. If these primates were to go extinct, then it could cause other incredibly negative side effects. It is important that we remain aware of all endangered species. We must show a significant amount of consideration for their well being.
There are many factors that are causing the endangerment of various primate species around the world, but one of the most powerful factors is typically human activity. One of the most rare species of lemur on Earth exists in Madagascar, and it is known as the Northern Sportive Lemur (iucn.org). An important fact on the country of Madagascar is included in the Conservation International: “Sadly, Madagascar is also one of the most heavily impacted countries on Earth in terms of recent habitat destruction” (conservation.org). As almost all primates, the main cause to the endangerment of the Northern Sportive Lemur is generally human activity. The International Union for Conservation of Nature (IUCN) provides several important factors caused by humans that influence the endangerment of these species by stating, “The main threats are habitat destruction, particularly from the burning and clearing of tropical forests the hunting of primates for food, and the illegal wildlife trade” (iucn.org).
A variety of different steps can be taken in attempting to raise the population of the Northern Sportive Lemur. As it is stated in the Conservation International, because of the current political status in Madagascar the environment in which the Northern Sportive Lemur lives in is becoming an even more detrimental habitat each day, and this is greatly caused by the unresolved poverty and hunting laws within the island country  (conservation.org). If specific laws were put into place to help benefit the well being of these lemurs then things could improve. A solution needs to be developed that involves the people of Madagascar because they are one of the main factors in the endangerment of the Northern Sportive Lemur. The only problem is this can be generally hard because of the current political status in Madagascar. In this case, the work can be greatly left upon conservationists to find the solution.
There are many reasons why all organisms on Earth should attempt to refrain from becoming extinct. Every organism on Earth has its role in the environment around it. Each life cycle consists of many key parts that are necessary for successful circulation, and each organism on Earth plays a role in at least one life cycle. It is stated by the Madagascar Biodiversity Partnership, “people who share a home with this lemur can become direct beneficiaries of the conservation of the Northern Sportive lemur” (madagascarpertnership.org). There are many factors within the environment of the Northern Sportive Lemur that benefit from its existence. Without it, many aspects of the Northern Sportive Lemur’s environment, its predators, or even the substances it consumes can have drastically negative effects placed upon them if this lemur were to go extinct.
The existence of all primates is equivalent to the existence of all things on Earth. Every thing on Earth plays its role in the environment in which it exists, and without it many factors of that environment would be at a total loss. The Chairman of the IUCN, Russel Mitermeir, presents a very important fact on all primates by stating, “more than 90 percent of all known primates occur in this endangered biome” (iucn.org). By stating this, Mitermeir is describing the importance of primates in the tropical rain forest biome. The importance of primates also greatly falls under the fact that they are our most significant and similar ancestors. The existence of all primates is greatly important in broadening our understanding of ourselves as humans as well as our history.
It is necessary for us to acknowledge the existence of all living things in this world. We also must consider the well being of all endangered organisms on Earth. Without them we would be at a loss with many things in this world. We must remain aware of the factors that are causing the endangerment of various species, and this is mainly insightful because we can typically be one of the factors that cause endangerment.

I enjoyed both of these papers. I liked how Sophie told us why it is hard to get land put aside to save the Northern Sportive Lemur, by giving some information about the situation in Madagascar. Both papers are right though that most of the endangered lemurs are endangered because of humans. It is only fair and responsible that since its our fault the lemurs are at risk of being lost that we should do everything in our power to save them.

It is mentioned in the blog about the blue-eyed black lemurs that the primates have been on the critically endangered list for thirty-nine years, which seems a long time without a positive change in numbers, or extinction. Is there an actual number associated with that term? Also, if it is difficult to arrive at an “accurate count “, how is it they can say that it is possible that there is only 1000 blue-eyed black lemurs left in the wild. If it is truly difficult to attain a precise count, couldn’t it also be possible that there are 10,000 left in the wild. I don’t want to sound insensitive, and I believe that every species deserves their chance at a natural selection. I just find it interesting that a species could be critically endangered for that length of time.

To answer your questions, Mike, one must first understand the definition for "critically endangered". This term is derived from the IUNC and is actually a very long definition where several criteria must be met (see page 21 of this link: http://jr.iucnredlist.org/documents/redlist_cats_crit_en.pdf). To briefly summarize it means that a population has drastically decreased in size or is not growing at what is considered an expected (and therefore safe) rate for the population to continue to live in subsequent generations, loss of lands to which the species can adequately exist, and/or not meeting a minimum number of sexually mature individuals. So given the lack of change in numbers of the blue-eyed black lemur over the last thirty-nine years that would explain why it remains on the critically endangered list, not to mention the environmental degradation that is on-going throughout Madagascar. All of these inferences have been confirmed through the IUNC website, as well (http://www.iucnredlist.org/details/8211/0).

As for not getting an accurate count of the species, the IUNC also addresses this in the first link I provided, but I will instead speak to the personal accounts I have heard from primatologists who I know who have or continue to work in that area of the world. Seeing lemurs is incredibly difficult because of where they reside in the forests (high in the canopies). These species also tend to be very fast, which increases the level of difficulty in identifying the species and individuals. So it can sometimes be a case where someone thinks they are seeing two different lemurs in the same day but they actually saw the same one. As for the counts being radically off by several thousand I doubt that because these counts are based on specific methods that do not allow for that type of error.

Also, due to the very specific threats identified as leading to the critically endangered status of these lemurs one may have a difficult time saying that they are "natural" when they are due to man manipulating the environment at a rate that is not meant to aid in survival of our species. The specific threats against these species that may not be as natural as one may think include forest fires, slash and burn agriculture, and mining. Now, we are getting into a grey area of definitions because one's definition of natural vs man manipulation does vary, but in general when it comes to conservation issues most scholars do not consider man-made threats as natural.

It appears that although we can identify the problem that humans pose on endangered species, it is hard to get them to stop. How do you educate people that use these animals for both food sources and financial gain? Some of these outlying areas are poor with few opportunities for work. It seems there are several problems that need to be corrected. One is how to fund Game Wardens to enforce laws to make sure these beautiful creatures don't go from endangered to extinct. While this would employee some, more jobs need to be created for others. Education would also help but only if people were able to support themselves.

They both bring light to a problem we have in our lemur population. Not many people are aware of this issue. If i didn't take this class I would have never thought about this problem. You do hear about other animals but not the small guy. Now you know why you are hearing about them more in kids movies. Their are groups and people trying to bring awareness to use.

The lemur is so cute! I had no idea there were only two primates that have blue eyes! Such a cool fact.

Both of these papers were very well written and gave a very good insight on how endangered lemurs are in Madagascar. I'm a person who has a soft spot for animals and hearing that their environments are being destroyed is very sad. I do think that we need to do everything in our power to save endangered animals like lemurs and since we are the cause of them being endangered.

Both of these papers are really well written. I liked how both of you discussed in-depth ways to help save these species instead of just educating us on why they are endangered in the first place. Not to mention both of these lemurs are adorable, I definitely don't want to see them go extinct!

Unknown said...

I love lemurs and both of these paper are definitely well-written to get the message out to help save the endangered species.

Richard Buma said...

I thought both papers did a very good job of showing the problem these primates are encountering. Both provided adequate information outlining the cause and potential solutions. When animals go extinct there is not telling what the fall out will be.

with many animals being extincted now days, we need to be more careful of what we do and a way to protect them. Its sad to see animals being gone and we cant do anything about it. Both essays are very beneficial and informative. There should be something done to help save those animals.

i I agree full heartily with what both these people are trying to say. Both these papers where very well written.

How can anyone want to ruin these little guys habitat? They are adorable! It is very sad that Madagascar is one of Earth's most impacted countries from human habitat destruction. It's obvious these two papers stress the decreasing population of lemurs. I hope these little creatures survive for years to come.

These were very sad essays to read. Unfortunately it is obviously true that humans are a main reason for deforestation and the extinction of many animals. By educating the public on these issues you are spreading awareness.

I cannot think of another reason for the endangered status of most primate species than that of human activity. There are always negative side effects when a species goes extinct, even if we don't know about them. I find our species hard to understand, we destroy so much of our home without a thought. Poverty is often the cause of our destructive ways, as with slash and burn agriculture, but greed is the other major factor. I hope the lemurs of Madagascar and their habitat can make a come back. The eco-tourism income in that part of the world is quite lucrative and I am hoping this factor will encourage the government and the people in Madagascar and around the world toward conservation.

Steven Benton said...

Deforestation is a key factor in why we loose very interesting primates like the Blue Eyed Black Lemur. Sometimes I wonder if these construction workers or loggers that take down these forest would put their own selves into the situation that these animals have to go through.

These cute little lemurs are being endangered by us humans, like usual. However, Its interesting that these little fellas eyes are blue. As said before, why won't we leave the area where we know they live alone?

we talked about primates in class recently and then i wrote a paper on primate and extinction. its so crazy how many animals are becoming extinct, they all take a part in our ecosystem and it effects everyone somehow when primate go extinct.

thanks

Julian Anderson said...

Both of these papers did a very good job of showing the problems these primates are encountering. Most of these problems stem from humans causing deforestation and the extinction of many animals. Both provided adequate information outlining the cause and potential solutions for deforestation and the extinction of many animals.

Sinclaire Baker said...

Both of these were a really good read. Since we already talked about primates i knew a little of what they were taking about. But its sad how animals are becoming extinct, in my opinion it is humans fault. But both articles showed some solutions i think we all should look into to help save our animals.

They did a great job with the organization of each paper/article. The first thing i thought was "they are so cute".Now I feel bad because humans are the reason that they are in danger. These ladies did a great job of shining light on this problem.

It still amazes me how animals could be extinct. and it is sad that we us humans play a huge role in it. i enjoyed this article

They both shed light on a challenge that our lemur population is experiencing. This is a problem that few people are aware of. I would never have considered this issue if I hadn't taken this class. Other creatures are mentioned, but not the little one. Now you know why you're hearing more about them in children's films. There are organizations and individuals working to raise awareness about the usage of tobacco.- Makala Reynolds
