Bukit Lawang ePaper created with educational purpose as a research to share important information about flora
and fauna in Gunung Leuser National Park. We are committed to build professional education networks in running the ecotourism
program in Bukit Lawang, North Sumatra, Indonesia. Bukit Lawang Ecotourism established at 2014, comes alongside
its main mission to empower local community in Bukit Lawang and expected to become a guidance for your trip during your holiday
and your adventure in Sumatra. We also offer you our tour package such as jungle trekking, village tour, rafting and many more
activities in the jungle. We hope this program can empower local communities to be able to comprehend ecotourism program.
Many often mistaken to recognize chimpanzee and bonobo, they are two separate species within the same genus. Chimpanzee and bonobo are 99.6 percent genetically similar to each other, but have different appearances and vastly unique social behaviors.
The biggest differences between chimpanzee and bonobo are in how they govern or rule their societies. Chimpanzees are led by an alpha male and tend to maintain order through aggression, while the bonobos are dominated by females and keep the peace through sexual activities.
Chimpanzee and bonobo share 98.5 - 98.7 percent of their DNA with human, 97 percent hold by orangutan, and 96.5 percent hold by gorilla.
Chimpanzee (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Homininae, Tribe: Panini, Genus: Pan, Species: Troglodytes).
Bonobo (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Homininae, Tribe: Panini, Genus: Pan, Species: Paniscus).
Wild chimpanzees only live in Africa. Their habitat is widespread from eastern Tanzania to Guinea or Senegal. Like us, chimps are highly social animals, care for their offspring for years and can live to be over 50. In fact, chimpanzees are our closest cousins; we share about 98.7 percent of our genes.
Gorilla is the largest extant genus of primates by physical size. Gorillas stick to a mainly vegetarian diet, feeding on stems, bamboo shoots and fruits. Western lowland gorillas, however, also have an appetite for termites and ants, and break open termite nests to eat the larvae, that's why the gorillas can be classified as omnivores. Gorillas are some of the most powerful and striking animals, not only for their size and force, but also for their gentle human like behavior. They play a crucial role in local biodiversity, roaming through large territories and helping, for example, to spread the seeds of the fruit they consume.
There are two species in the genus of gorilla, they're eastern gorilla and western gorillas. As a primate in fourth position to share 96.5 percent DNA with humans (after orangutan), make their homes in central and east Africa.
Gorilla (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae. Tribe: Gorillini, Genus: Gorilla, Species: Gorilla).
Sumatran orangutan (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Subfamily: Ponginae, Genus: Pongo, Species: Abelii).
The biggest male mountain gorillas reach an average of 1.8 meters tall (when standing upright) and weight 230 kg.
Orangutans are the two exclusively Asian species of extant great apes. Natives to Indonesia and Malaysia, which can be found only in the rainforests of Borneo and Sumatra (Gunung Leuser National Park). Orangutans are the largest apes that live in the rainforest of southeast Asia, these apes mostly live on the trees (they are arboreal) and swing from branch to another branch using their arms.
Adult males weigh between 50 to 90 kg and can stand between 1.25 to 1.6 m in height. while the adult females weigh between 30 to 50 kg and stand about 1 to 1.1 m in height. So, it makes orangutans are the world's largest arboreal (tree—dwelling) mammals. The arm span of adult male orangutans may reach 2.2 m in length.
