The Chaparral Biome
Transcript of The Chaparral Biome
By: Kathleen Shatinsky
Where are chaparrals located?
Chaparrals are found in California; Central Chile; Cape Province, South Africa; Southern and Western Australia; and in the areas surrounding the Mediterranean Sea.
What is a Chaparral?
The chaparral is one of the smallest, but most varied, biomes. They have climates similar to those of deserts, but can support more vegetation. A chaparral can be found on a flatland, a rocky hillside, or even a mountain slope. Chaparrals are found on almost every continent, but the most known chaparrals are found in California and around the Mediterranean sea.
What is the climate of a chaparral like?
Although the inhabitants of each Chaparral biome are greatly varied, all chaparrals have the same basic climate. Chaparrals have hot, arid summers, and cool, rainier winters; the fall and spring seasons are moderately warm with somewhat more rainfall. During the summer, chaparrals are especially prone to wildfires, but coastal chaparrals often have fog during the summer, as well. Chaparrals typically receive 12-40" of rainfall yearly.
1.) The blue oak tree of the California chaparral has thick tree back that lessens the severity of burns from wildfires.
2.) The olive tree native of the Mediterranean chaparral has small leaves with protective coatings that slow the process of transpiration and conserves water for the plant.
3.) The golden jackal of the Mediterranean chaparral has a thick coating of fur that grows in to insulate it from the cooler chaparral winters.
4.) The black-tailed jackrabbit of the California chaparral has large ears that help it to regulate its body temperature.
5.) The island gray fox of the California chaparral is smaller than its ancestral gray fox, which allows it to live off less land and resources.

2.) Olive Tree
3.) Golden Jackal
4.) Black-tailed Jackrabbit
5.) Island Gray Fox
How do humans affect this biome? And what can we do to help it?
There are multiple human impacts in the chaparral biome. Building development and pollution, especially in the California chaparral, destroys resources for the animals of the chaparral. However, the leading threat to chaparrals are wildfires. Although wildfires started by lightning storms are natural for the chaparral, frequent human-started brush fires can burn plants beyond recovery, and ultimately depletes an area of all resources for chaparral animals. Humans can help this biome by not exposing the chaparral to things that may spark a brush fire, such as fireworks, campfires and bonfires, cigarettes, and barbeque grills.

What abiotic factors affect the Chaparral?
Many abiotic factors affect the chaparral. As a result of the hot daytime temperatures and the cooler temperatures of the night, many chaparral animals are nocturnal. The lack of rain causes the organisms of the chaparral to adapt to living on very little water. Lastly, the arid wind of the chaparral causes water to evaporate faster, and often contributes to the spread of wildfires.
What are some symbiotic relationships of the chaparral?
1.) An example of mutualism in the chaparral would be the blue oak tree and the common sage brush, because they are both producing for the other organisms of the chaparral without overpowering each other.
2.) An example of commensalism in the chaparral would be the red-winged blackbird and the torrey pine, because the blackbird benefits by eating the dropped seeds of the tree, but it does not benefit or harm the tree.

What is the top carnivore of the chaparral?
The top carnivore of the chaparral is the puma. Its niche in the chaparral is to keep the populations of other animals in check, as pumas would eat practically any animal from a small insect to a large deer.
Dandelion, Sagebrush, Spanish Bayonet, Manzanita, Coyote Brush.
Black-tailed Jackrabbit, California Quail, Cactus Wren, Greater Roadrunner, White-tailed Deer.
How is the chaparral Important to the rest of the world?
The chaparral is important to the rest of the world because its unique climate and weather patterns allows a diverse array of native organisms that are not found anywhere else to thrive.
What is an example of competition in the chaparral?
An example of competition in the chaparral would be the puma and the coyote. The puma and the coyote are competitors because since they are among the top carnivores of the chaparral, they target a lot of the same prey. Although the puma would target coyotes as prey, the coyote competes with the puma by occasionally hunting in packs, which gives it an efficient hunting advantage over the more solitary puma.
