BIOL 3 - 34090]]> 2023-10-02 00:22:24 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2727797452 Introduction simoneowens15 https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2727812866 The Chaparral biome is characterized as being very dry and hot with very mild winters. The annual average temperature range is between 30° and 100° F, with the average temperature in the coldest months being 64° F, thus making fires and droughts common. 

Most of the biome receives approximately 10-17" of rainfall, and up to 40" at high elevation locations in the winter.

The Chaparral communities occur Mediterranean-type climates, which can be found along the west side of continents with westerly winds, such as in California, Chile, Spain, South Africa, and Australia. Also, the biome can be categorized into three types, each with varying elevations:

Chamise-Redshank Elevation = 4,000 feet
Coastal Scrub Elevation = 3,000 feet
Mixed Chaparral Elevation = 5,000 feet
Montane Elevation = 3,000 to 10,000 feet

Chaparral occurs upon thin, porous, and rocky soils that are considered low in nitrogen, potassium and phosphorous.

Ecological Role: This species constantly eat and do not require much water, as they meet most of their water needs from the plant material they consume. They primarily practice herbivory as they consume twigs, young bark, and cacti. This grazing also makes the brush more manageable, limiting the spread of unnecessary fires (not the fires that are useful for this biome).]]> 2023-10-02 00:59:33 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2727821249 Salvia leucophylla(Plant) https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737573989 The Salvia Leucophylla plant is a good example of Uniform dispersion. This sage plant releases a toxin that kills the plant in its nearby vicinity. Sage plants create an empty area around them because the toxins they release make the nearby soil unsuitable for other plants to grow. This results in a clear space around the sage where nothing else can thrive.

This distribution pattern is common among species in which individuals gather into groups for positive interactions with predators or to increase hunting efficiency. The reason why these elephants are in this type of distribution is due to their traveling in herds and their social relationship as well as their having to live in national parks in order for them to remain safe and out of harm's way now that their habitat is being destroyed. ]]> 2023-10-09 05:03:51 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737591639 Dandelion https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737594545 random dispersion comes from dandelions and other plants that have wind-dispersed seeds. The seeds spread widely and sprout where they happen to fall, as long as the environment is favorable—has enough soil, water, nutrients, and light. ]]> 2023-10-09 05:09:06 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737594545 Human Disturbances for Chapparal https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737601482 Human actions in the Chaparral, a type of natural environment, have caused problems like diverting water, building dams, and introducing invasive plants and animals. These activities have harmed the area and put many species at risk of extinction, including the California condor. People are hurting the plants and animals in this place by building things like houses and roads. These actions destroy their homes and only help humans, without thinking about how it affects the whole environment. ]]> 2023-10-09 05:21:10 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737601482 what is being done to fix the human disturbances for chaparral biome https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737607013  Most efforts to restore chaparral have involved letting nature recover on its own by removing things that harm it, like fire or human disturbance, so that plants, animals, and soil can heal naturally. it means taking steps to stop non-native plants and animals that are causing problems from taking over and harming the natural environment. ]]> 2023-10-09 05:30:34 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737607013 Lepus californicus gestation period https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737611307 Gestation and Nesting: The gestation period ranges from 41 to 47 days.

Sexual maturity is attained at about the same time, but young females do not breed until early in the year following their birth.]]> 2023-10-09 05:42:48 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737613947 How many offspring are usually produced?What type of survivorship curve does this organism produce https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737621709 Black-tailed Jackrabbits mate year-round. They have one to four litters per year with one to eight young per litter. They have type III survivorship.

Next would be primary consumers like hyenas and wrens specifically cactus wren, then lastly would come secondary consumers which could include pumas and foxes. ]]> 2023-10-09 06:04:51 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737629615 Chamise (plant) (Adenostema fasciculatum) simoneowens15 https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737667533 Interesting Fact: Chamise has an extensive root system, with the main roots having been excavated at a depth of around 25 feet.

Ecological Role: Chamise has small, resinous leaves that are highly flammable during the dry season, yet burning is disadvantageous to Chamise. This would indicate that this is beneficial to another species that needs the fire, indicating an almost commensalism relationship. It is also a victim of predation.]]> 2023-10-09 06:45:24 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737667533 Rhizobia (bacteria) simoneowens15 https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737676978 Interesting Fact: The ability for this bacteria to take in nitrogen from the atmosphere and pass it on to the plant, allows the plants to grow in soil low in nitrogen, which is seeing the chaparral biome.

Ecological Role: Rhizobia are a bacteria that fix nitrogen after becoming established inside the root nodules of legumes. This aids in the nitrogen cycle and exemplifies a symbiotic relationship as the bacteria fixes the nitrogen and the plant is able to use this.]]> 2023-10-09 06:54:24 UTC https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737676978 References simoneowens15 https://padlet.com/simoneowens15/i6dn4r5cvec0xr7n/wish/2737689377 World Rangeland Learning Experience, Retrieved from,
