The Trans Pecos of Texas By: James Dinaso Plains Bristlegrass
Indian Grass
Chinograss
Pinon Pine
Arizona Cottontop 5 Producers of This Region 5 Biotic Factors of This Region 5 Consumers Antelope, Rabbits, Snakes, Birds, Rodents Grasses, Trees, Animals, Snakes, Birds and many more things. 5 Abiotic Factors Rocks, Mountains, air, water, sun, sand and alot more 3 Plants and their Adaptions to the Trans Pecos CLIMATOGRAM! Temperature and precipitation The prickly pear cactus has adapted to the trans pecos, because of the modified parts and functions.
One body part is the thickened outer stem, it does lots of things and moves and stores food.
It always has modified leaves and colorful flowers. Their roots dig into the ground and become strong anchors, and the leaves have long hairs that catch moisture. References: Where I found the Info The Pinon Pine Tree has adapted to the Trans Pecos, because of the ability to grow in different types of soil ( igneous substrates).
These trees are small to medium size evergreen trees.
The Mexican pinon pines grow at higher elevations and the papershell pinon grow at lower evelations.
They are also known for there edible seeds and other uses including medicinal and materials for fashioning tools. The Cottonwood tree has adapted to the Trans Pecos because they grow along streambanks in the dry mountains and desert shrublands and grasslands. They grow at elevations from 900-2450 meters.
They are found along narrow, periodically flooded benches adjacent to streams and smaller rivers.
They pioneer colonizes sandbars and fresh alluvium in areas of full sun.
They tend to become so populated that the form a dense closed canopy of cottonwoods.
The cottonwoods flowers bloom in May and before or during leaf emergence and the fruits in May-July with seed dispersal in June and July. The elf owl has adapted to the Trans Pecos by having remarkable hearing that allows it to pin point the location of its prey.
It also has special feathers that muffle the noises made when flying, making it unnoticeable.
The owl feeds on caterpillars, scorpions, crickets, moths, and beetles. 3 Animals and their Adaptions to the Trans Pecos The Jackrabbit has adapted the Trans Pecos by having high visibility of the pastureland to spot predators first before they spot it.
They are associated with pastures grazed by livestock.
The Jackrabbits live in brushlands, prairies and meadows. The Roadrunner has adapted to the Trans Pecos by having acute senses of survival, and they have the advantage of being able to survive in fast changing environments.
They normal weight about 25 to 40 pounds, and they live in the open plains in the west and brushy areas in the East. Roadrunner Elf Owl JackRabbit Pinon Pine Tree Prickly Pear Cactus 5 Food Chains in the Trans Pecos Prickly Pear Cactus ------ cactus wren---- western diamondback ----- Great Horned Owl ----- mushroom Agave ---- mexican long nose bat ----- tarantula ---- Painted redstart ------ western diamonback ---- mule deer ---- coyote ----- fungi Creosote bush ----- pronghorn antelope ----- coyote ------ mushroom Sotol ---- javelina ----- mountain lion ----- bacteria Oaks ----- squirel ---- javelina ----- coyote ---- worms Food Web -------- ------ ----- ------- -------- ------ ----------- ------- ---- --------- -------------------------------------- ------ mushroom ----------------- --------- ------- ------------------ --------- -------- ------------- ----------------------------------------------- Interealtionships Predations are coyotes, and mountain lions. Parasitism- fleas on the coyotes Commensalism - is the birds or owls making nest in the trees or in the cactus Mutualism - the decompsers and the dead animals because the nutrients that is in the dead animal needs to be in the soil. Competition - is going on all throughout my ecoregion because the trees have competion to get the sunlight and the consumers have competion to get to the food before any other ones. 3 Limiting Factors in the Trans pecos Limiting Factor 1: Hunting is a big problem because if there is no animals at the top of the food chain there the others under them will grow to large and then there will be a problem. Limiting factor 2 : Fencing is also becoming a big problem because the area that the animals have is getting smaller with the fences being put up. Limiting Factor 3: Over population is becoming a problem because if the hunters shoot the bigger game ( coyotes, mountain lions) the animals lower in the food chain will begin to get larger. 2 Ways that Humans Benefit the Tran Peccos 1 way that humans benefit the ecoregion is that they make new parks and protect lands. Another way the humans benefit the ecoregion is that the are protecting the animals and certain species of plants and they are making live easier. 2 ways that humans harm the Trans Pecos 1 way that humans harm the ecoregion is by hunting all of the wild game. Mule deer, coyotes, mountain lion, etc. If they hunt more than populations of other animals will grow and the number will be too big to contain. Another way that humans harm the ecoregion is by building things in the Big Bend Territory. They build houses and roads and all that stuff and soon there will be no more trans pecos region of Texas. The Way a drought might affect the Stability of the Trans Pecos I think that a drought probably would not affect my region because it is mostly already desert so. it would not affect the region. How a Hurricane Might affect the Stability of the Trans Pecos I think that if a hurricane did ever hit the Trans Pecos, that it might harm the region very badly, because it would cause floods and all that stuff because the soil, does not hold water good. A hurricane might destroy my region. I found alot of the info at: www.tpwd.state.tx.us/kids/
