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.

Anth 102 1501: Introduction to Physical Anthropology
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 Sclater’s 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 flower’s
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.

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.
