Question

okapi
the purpose of this project is to introduce students to food webs, environments, trophic levels, and many other things. students will make a google slide presentation to show information obtained from their research.

student will then research:

• what is the basic name of the animal?
• what is the genus and species of the animal?
• what is the animals ancestor?
• what environment does the animal live in?
• give details of the environment - biome, weather, climate, zone in the world
• would your animal be able to live in a different environment? why or why not
• what does the animal eat for food?
• is the animal an omnivore, carnivore, or herbivore?
• what animal is a predator to the students animal?
• what is the prey to the students animal?
• what adaptations does the animal have that allow it to survive?
• how long is their gestation period?
• how many offspring are usually in their litter?
• is there anything unique or unusual about their mating/gestation period?
• what is human relationship with the animals in your environment?
• what ecological relationship does the animal have with others if any?

(mutualism, competition, parasitism, commensalism)

Explanation:

Identify classification and ancestry

Using the Biological Classification knowledge point, we identify the okapi's taxonomic details and evolutionary history.

• Common Name: Okapi
• Scientific Name: Okapia johnstoni (Genus: Okapia, Species: johnstoni)
• Evolutionary Ancestor: The closest living relative and evolutionary sister taxon is the giraffe (Giraffa camelopardalis). They share a common Miocene ancestor, such as Canthumeryx or Samotherium.

Describe habitat and adaptability

Using the Environmental Adaptation knowledge point, we analyze the okapi's native environment and its capacity to survive elsewhere.

• Environment: Tropical rainforests (specifically the Ituri Rainforest in the Democratic Republic of the Congo).
• Climate/Biome: Dense, high-canopy tropical wet forest with high humidity, heavy rainfall, and warm temperatures year-round.
• Adaptability: No, they are highly specialized. They rely on dense canopy cover for camouflage, constant high humidity, and specific understory clay/vegetation, making them poorly suited to arid, temperate, or open grassland biomes.

Determine diet and trophic level

We analyze the okapi's feeding habits and its position in the local food web.

• Diet: Herbivore. They feed on tree leaves, buds, shoots, fungi, fruits, and charcoal/clay (for minerals).
• Predators: Leopards (Panthera pardus) are their primary natural predators; humans also hunt them.
• Prey: None, as they are strict herbivores.

Analyze physical and behavioral adaptations

Using the Environmental Adaptation knowledge point, we examine the specific traits that aid the okapi's survival.

• Camouflage: Zebra-like striped hindquarters break up their outline in the filtered forest light.
• Prehensile Tongue: A long, blue-black prehensile tongue (similar to a giraffe's) allows them to strip leaves from branches.
• Scent Glands: Interdigital glands on their feet secrete a tar-like substance to mark territory.
• Infrasonic Communication: They produce low-frequency sounds below human hearing range to communicate without alerting predators.

Detail reproduction and ecological relationships

We outline the reproductive biology and community interactions of the okapi.

• Gestation Period: Approximately 14 to 16 months (around 420–450 days).
• Litter Size: Typically a single calf.
• Unique Mating/Gestation: Calves do not defecate for the first few weeks of life to prevent predators from tracking their scent.
• Human Relationship: Threatened by habitat destruction (deforestation, mining), poaching, and civil unrest.
• Ecological Relationships:
• Mutualism: Seed dispersal of forest plants via defecation.
• Competition: Compete with other forest herbivores (like duikers) for understory foliage.

Answer:

Here is the research profile for the Okapi project:

• Basic Name: Okapi (also known as the forest giraffe)
• Genus and Species: Okapia johnstoni
• Ancestor: Shares a common prehistoric ancestor with the giraffe (family Giraffidae); its closest fossil relatives include Miocene giraffids like Samotherium.
• Environment:
• Biome: Tropical Rainforest
• Climate/Weather: Hot, highly humid, and wet with high annual rainfall.
• Zone: Central Africa (endemic to the Ituri Rainforest in the Democratic Republic of the Congo).
• Adaptability to Other Environments: No. Okapis are highly specialized for dense canopy rainforests. They would not survive in open, dry, or cold environments due to their reliance on specific understory plants, high humidity, and camouflage.
• Diet: Herbivore. They eat leaves, buds, shoots, fruits, fungi, and even charcoal or clay for essential minerals.
• Predators: Leopards (Panthera pardus) and humans.
• Prey: None (herbivorous).
• Adaptations:
• Striped Hindquarters: Provides camouflage in filtered forest light.
• Prehensile Tongue: Long, dark tongue used to strip leaves from branches.
• Infrasonic Hearing/Vocalization: Communicates using low-frequency sounds that leopards cannot hear.
• Scent Glands: Located on their hooves to mark territory in dense brush.
• Gestation Period: 14 to 16 months (approximately 420–450 days).
• Litter Size: 1 calf.
• Unique Mating/Gestation Feature: Calves do not defecate for the first 4 to 8 weeks of life, an adaptation that prevents predators from finding them by scent while they hide in the vegetation.
• Human Relationship: Severely threatened by human activities, including poaching for bushmeat/skins, habitat loss due to logging and mining, and regional armed conflict.
• Ecological Relationships:
• Mutualism: Disperses seeds of the forest fruits they consume.
• Competition: Competes with other forest herbivores, such as duikers (small antelopes), for understory browse.
