Major threats

1) losing natural habitat.

2) illegal hunting.

3) Increasing human population on island and human distribution.

Three major threats to the komodo dragons

Major threats

1) losing natural habitat.

According to data Komodo dragons have been living on Indonesian islands from 900000 years ago, although they originated in Australia. From past 10 years Indonesian population increased, so the Komodo dragons facing habitat loss again human settlements. They are losing their natural habitat which made difficult situation to new born dragons. Before 900000years ago they were all over the Indonesia but after human activities they only can found in parts of the western and northern part of islands.

Major threats

(2) illegal hunting.

The primary threats to the dragon's survival include illegal hunting and loss of habitat to human settlement. As was the case with most large, spectacular animals the world over, Komodo dragons were sought as trophies by big-game hunters. They also are killed for skins and feet to make novelties. Early in this century, many Komodo dragons were trapped for sale to zoos and private collectors.

3) Increasing human population on island and human distribution.

Major threats

The current population of Komodo dragons seems relatively stable at about 5,000 animals. The dragon's limited distribution makes them highly susceptible to natural or human-caused events, such as storms, fire, or disease. On the northern coast, farmers employing slash and burn agriculture are destroying the dragons' forest habitat. Because of that destructions dragons are decreasing in numbers.

Major threats

Classification mapKomodo dragons’ phylum: Chordata

Chordata: Chordates form a phylum of creatures that are based on a bilateral body plan, and is defined by having at some stage in their lives all of the following. The phylum Chordata is separated into three subgroups (or subphyla). The invertebrate subphylum Tunicata consists of the marine tunicates, including the ascidians and salps. The invertebrate subphylum Cephalochordata includes the fishlike amphioxus (or lancelet). Amphioxus is a small marine animal that closely resembles the larva of the jawless fishes (class Agnatha). The subphylum Vertebrata is the largest chordate subgroup.

Classification mapKomodo dragons’ phylum: Chordata

Three organism from chordata:

1) LION2) Black mamba3) blue whale

Lion :

- Kingdom: Animalia, Phylum: Chordata, Class: Mammalia , Order: Carnivora, Family: Felidae, Genus: Panthera Species: P. leo , and sci. name: Panthera leo

- The lion (Panthera leo) is one of the four big cats in the genus Panthera and a member of the family Felidae. With some males exceeding 250 kg(550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in Sub-Saharan Africaand in Asia with an endangered remnant population in Gir Forest National Park in India, having disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India.

Classification mapOne of Three organism from chordata:

Black mamba :• Kingdom :Animalia, Phylum: Chordata, Subphylum: Vertebrata, Class: Reptilia,

Order: Squamata, Suborder: Serpentes, Family: Elapidae, Genus: Dendroaspis, Species: D. polylepis, and sci. name: Dendroaspis polylepis

• The black mamba (Dendroaspis polylepis) is the longest venomous snake in Africa, averaging around 2.5 meters (8.2 ft), and sometimes growing up to 4.3 meters (14 ft). Its name is derived from the black coloration inside the mouth rather than the actual color of the skin which varies from dull yellowish-green to a gun-metal grey. It is the fastest snake in the world, capable of moving at 4.32 to 5.4 meters per second (16–20 km/h, 10–12 mph).  The snake has an average life span of 11 years in the wild.

Classification mapOne of Three organism from chordata:

Blue whale: • Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Cetacea, Suborder: Mysticeti, Family: Balaenopteridae, Genus: Balaenoptera, Species: B. musculus, and sci. name is Balaenoptera musculus

• The blue whale has a long tapering body that appears stretched in comparison with the stockier build of other whales. The head is flat, U-shaped and has a prominent ridge running from the blowhole to the top of the upper lip. The front part of the mouth is thick with baleen plates; around 300 plates (each around one meters (3.2 ft) long) hang from the upper jaw, running 0.5 m (1.6 ft) back into the mouth. Between 60 and 90 grooves (called ventral pleats) run along the throat parallel to the body length. These pleats assist with evacuating water from the mouth after lunge feeding (see feeding below).

Consequences There would be some serious economical and environmental problems in future if komodo dragon become extinct. In Indonesia komodo dragons are main and interested subject for tourists because komodo dragon is the world’s largest ground monitor and also shares ancestor with dinosaurs. According to a statistic Indonesia earns more than 30% of economy from tourism. In addition if komodo dragon extinct than the tourism business will be broke in Indonesia. At other side some body part of Komodo dragon use to make novelties, so in that case the novelty business also going to affect if komodo dragon become extinct, which going to directly affect human lives economically. Which means the standard of human lives in Indonesia will become low. On other side as a result of an environmental impact food web would be majorly effect if komodo dragon extinct. In food web every species is very important, so if one species extinct than whole food web and eco- system will damaged. As a prediction If komodo dragon extinct than all the animals who were food source of komodo dragon will be increase in population, which going to extinct the other species which are the food source of over populated animals. And if it’s continues than it will cause to serious damaged to environment and eco-system. Human cannot live without his habitat so if the human’s habitat(ecosystem ) damaged than it could bring many difficulties for human lives.

Consequences

Personal Response Biodiversity important or not? Biodiversity is very important for survive any specie on earth. In fact Earth is an great example of biodiversity. Biodiversity means all different living things on earth, which relay on each other to survive. Biodiversity is important for survival because it source of food and Medication, evolution and living atmosphere to a human.

Firstly, biodiversity provides food to all species. Human is a omnivore animal which means humans relay on both vegetables and plant. If we think about biodiversity around us(human), we will come up with animals, plant and other living things which most we use for eating as a food, without that biodiversity we will not able to obtain food. in other side if we talk about medication that it also come from biodiversity. There is many organisms other than human which have totally different genes and antibodies than human. Some of them is used by human in past to defend various kind of disease. As an example penicillin fungi is used in many medication in modern days which is also a part of biodiversity. In modern time human uses many organisms to research and find medication. In short biodiversity is a very important factor for species.

Secondly, biodiversity was an important factor to cause evolution. Because of biodiversity species face conflicts and to avoid that conflict a species struggle with the situation and be successful to develop an abilities to defend that certain situation and once again species face a new conflict. This cycle helps them to evaluate(upgrade) their abilities. As an example humans were came from apes(according to scientists), in fact apes were hydrophobic. As time goes humans have to face certain kind of conflicts in past, so they built abilities to swim in water.

Lastly, biodiversity is also provides living atmosphere to species. All the species of kingdom plantea perform important role in ecosystem. Most species who lives on grounds need oxygen to survive. As a fact s species named algae provides 2/3 oxygen of world. There is many tiny species out in atmosphere which provides positive conditions to live. Conclusively biodiversity is very important factor for ecosystem.

Interesting Fact The world’s greatest monitor, komodo island monitor use poison to kill animals

Researchers have discovered that the bite of the world's largest lizard, the Komodo dragon, is venomous. The carnivorous beasts are unusual because they release their prey after biting them, apparently leaving the animals to bleed to death before eating them. But many experts have claimed the victims die after being infected with bacteria that cover the lizards' serrated teeth. Komodo dragons live on several Indonesian islands and typically grow to 3m long and weigh around 50kg. They lie in wait for prey and ambush them by charging forwards with their jaws open. The lizards can spend hours in one spot, waiting for wild boar, deer, goats and other large mammals to pass by. Scientists at the University of Melbourne used computer models to investigate the strength of the lizards' bite and found it was weak compared with other predators, such as the Australian saltwater crocodile.But magnetic resonance imaging scans revealed complex venom glands in the dragons' mouths that had never been documented before.
