https://bckbiologysfifield.weebly.com/
Classified as part of the biome: TAIGA or also called CONIFEROUS FOREST OR
BOREAL FOREST
Because of its size and location, it can share part of other biomes such as Northern Temperate
Coniferous Forest and Grassland prairies
The Taiga biome is located at what we might
call the top of the world, just below the Tundra
Winters are long (6 month) and dominated by very cold
weather with lots of snow throughout the winter;
temperatures range from -65° to 30° Fahrenheit.
Summers are warm with humidity and rain.
The Taiga biome doesn't really experience the seasons of
autumn and spring because they are so short-lived.
The majority of plants are coniferous (evergreen) trees,
although there are some lichens and moss. Deciduous
trees can be found in some pockets of Taiga biomes.
Temperate coniferous forests are found
predominantly in areas with warm summers and
cool winters, and vary in their kinds of plant life. In
some, needle leaf trees dominate, while others are
home primarily to broadleaf evergreen trees or a
mix of both tree types
Temperate grasslands lack the scattered
trees that are characteristic of savannas.
Temperate grasslands have distinct hot
and cold seasons and a moderate amount
of precipitation in the late spring and
early summer

https://bckbiologysfifield.weebly.com/
Wind: Where Yellowstone is for the most part directly in the centre of the Rocky Mountains, it enjoys
more rainfall and wetter, cooler western winds. However some of Yellowstone lies on the eastern
downhill slope of the Rockies, where it experiences a 'phenomenon' called the Chinook winds.
Light (insolation): Yellowstone experiences insolation levels ranging from 1.33 to 6.24 kWh/m^2/day
(kilowatt-hours per square meter per day) on average per month. Solar radiation is lowest during the
winter months of October, November, December January and February, and reach their peak in June
and July, the strongest summer months.
ATMOSPHERINC FEATURES:
9. Yellowstone National Park
https://bckbiologysfifield.weebly.com/
ATMOSPHERINC FEATURES:
Humidity: Yellowstone has a low relative humidity. Where there is low elevation, the temperatures
usually increase, which increases evaporation levels. However, particularly in summer, but also in the
winter months, when it is colder, evaporation levels decrease and humidity can rise to 40-45%
Precipitation: Precipitation is relatively low-moderate in the Greater Yellowstone Ecosystem with an
average annual rainfall of 15.4 inches and an annual snowfall of 72.1 inches. Rainfall in Yellowstone
varies in the forms of rain, snow and dew. Rain tends to fall at higher rates in the Spring and Summer,
where as in winter, water is distributed via snow.
Temperature: Due to Yellowstone's varied altitude levels from between 1,610 and 3,642 meters,
temperature and weather conditions vary. For example, the lower altitude regions and grasslands
can climb to even 30 degrees celsius in the summer, but remain at maximum 25 degrees further
up the mountains, whereas temperatures can fall to below -20 degrees celsius in the higher winter
season.

SOIL FEATURES:
Nutrients: Yellowstone, characteristic of a taiga biome, has typically nutrient-poor soil. Due
to decomposers taking longer to decompose the needles on the forest floor, nutrients is
often restored more efficiently with natural fires.
Fire: Fires are an extremely significant factor for the forest, especially in Yellowstone. It
rejuvenate forests on a grand scale.
Composition: Soil in the taiga biome is called
spodosol. Spodosol soil is described as typically having layers of
organic topsoil with a leached grey subsoil and an iron-rich
clay/loam layer below.
Temperature: On average annually, between 6 and 8 degrees
celsius, and less than 8 degrees in the summer.
14. The Engelmann spruce is
often found along creeks
or wet areas and has
sharp, square needles
that grow singly. It's
cones hang down and
remain intact, with no
bract between
scales. The trees can
grow to up to 100ft tall.
Engelmann Spruce
(Picea engelmannii):
It has very thin
bark, which accounts for
its susceptibility to being
killed in fires. Its needles
are in groups of two, and
the tree can grow to 75ft
tall.
Lodgepole Pine (Pinus
contorta):
The Rocky Mountain
Juniper is a species of
Juniper that varies in size
from a small tree to a
shrub, and grows in
lower elevations. It has
scale-like needles and it's
cones are small and
fleshy. Grows up to 30ft
tall.
Rocky Mountain
Juniper (Juniperus
scopulorum):
It has needles that grow
in groups of five, reduces
erosion, retains snow,
acts as a nurse plant for
other species, and grows
seeds particularly
important for the diets of
grizzly bears. It grows to
up to 75ft tall.
Whitebark Pine
The Douglas-Fir has thick
grey/brown bark which prevents
damage from low-intensity fires

300,000,000,000 PH 29% of landmass
Number 3: Yellowstone and much of North America have experienced numerous periods of glaciation during the last 2.6 million years.
**Glaciers result when, for a period of years, more snow falls in an area than melts. Once the snow reaches a certain depth, it turns into ice and begins to move under the force of gravity or the pressure of its own weight. During this movement, rocks are picked up and carried in the ice, and these rocks grind Earth’s surface. Ice and water erode and transport earth materials as well as rocks and sediments. Glaciers also deposit materials.

Wetland consisting of marshes or swamps; saturated land.
Having the ideas of major biomes in the states the greater Yellowstone stands, we can safely say that there is a Major Biome (Which has the most part of GYE) and minor biomes.
What are the biomes found in GYE?
The parks in GYE has though have similarities also have its differences. So in further slide, we can safely distinguish the biodiversity in GYE.
Because the Greater Yellowstone Ecosystem’s location and size, it can share
We can distinguished the biome of Greater Yellowstone by identifying two different parks with different locations in the globe.
SOIL” The soil quality of a taiga biome is very poor. This poor quality is due to the fact that the taiga has such low temperatures for such a long period of time
Mosses are defined as simple plants with the most basic of root structures, leaves, and stems.
LICHENS (composite organism) a simple slow-growing plant that typically forms a low crusty, leaflike, or branching growth on rocks, walls, and trees. (fungus and algae)
Deciduous trees are giant flowering plants. They include oaks, maples, and beeches, and they grow in many parts of the world. The word deciduous means to “fall off,” and every fall these trees shed their leaves. Most deciduous trees are broad-leaved, with wide, flat leaves.
If you want to convert Celsius to Fahrenheit, just multiply the temperature by 1.8 and then add 32 to the product. If you want to convert temperature from Fahrenheit to Celsius, subtract 32 from the number and then divide the difference by 1.8.
32 F= 0 Celsius
Winds: These winds come from the western coast as usual and once they are blocked by the mountains, they rise, becoming cooler and releasing their moisture via rainfall, snow or dew, so once they come back down the eastern side of the mountains they are dry and become rapidly warm upon decent. The Chinook, known as 'snow-eater' from it's original meaning in Native American, melts the snow and leaves a dry, warm wind blow.
Ang humidity o halumigmig ay ang dami ng singaw ng tubig (water vapor) sa hangin.
*HUMID – more hot than cold
Low Humidity Day: The clothes would dry out rather rapidly
High Humidity Day: The clothes would take literally forever to dry in comparison as the high humidity in the air would help them retain their moisture content.
Plants that survive the heat: Bougainvillea, Sunflowers, Aloe Vera
Okra, Corn, Cucumbers, Beans, Eggplant
Koalas
Temperature: This affects both the plant, animal and non-living system, which will vary in each climatic region.
Ammonia – Toxicity to animals
PH – Fish and their eggs, high PH Algae
Nitrogen and Phosphorous are needed for plant growth
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.
Normal water (drinking): Nitrate 10mg/l
Alkalinity is the capacity of water to resist changes in pH that would make the water more acidic.
Fire season - mid-June through September.

What we see in the videos are example of Geysers (hotsprings that erupt periodically), Fumaroles (vents or holes where steam rush into the air), hotsprings, mudpots (water-saturated (or clay) are affected by the steam below), Steam Vents – cracks in the surface of the ground through pressurized steam from below (it makes hissing sound , sometime)
*Fumaroles ang hottest surface (opening near or in a volcano) – yung water, nacoconvert into steam.

Decomposers are heterotrophs that breakdown dead or decaying matter but differ from detritivores in that they do not internally digest the matter but rather use chemical reactions.
Lodgepole Pine - The predominant species in Yellowstone is the lodgepole pine, which accounts for 80% of the total forest area in the park.
Douglas - This popular tree resembles the fir and the hemlock, which gives it it's name Pseudotsuga, meaning "false hemlock".
Whitebark pine is a high-elevation conifer that grows in conditions too inhospitable for most other species. It only grows above 7,000ft and grows in high wind areas and low nutrient soils.
Butterfly: The Checkerspot butterflies roost in conifer trees.
Beetles: These beetles were presumed to only be able to survive in warmer temperatures but have now adapted or rapidly reproduce during the warmer seasons and can withstand winter. The beetles decimate the pines of Yellowstone.
Moth: They migrate to survive
1.This chipmunk is one of three common to Yellowstone and the smallest member of the squirrel family.
2.Snowshoe Hare (Lepus americanus) They are mostly nocturnal, have large feet - a structural adaptation for optimum ability to roam on the snow, white winter coats for camouflage and grey summer coats.
3.Yellowstone is the only place in the United States where the bison population has been continuous since prehistoric times. Thepredators of adult bison are wolves and grizzly bears, however dead bison are a very important source of food for other carnivores of the ecosystem.
4.Yellowstone is home to an estimated 10,000-20,000 Elk in the summer and are the most popular ungulate in the park. While numbers are abundant in summer, they drop to less than 5,000 in winter.
Wolves:Yellowstone Park in 1995 exhibited no wolves. The previous species of wolf 'native' to Yellowstone was hunted to extinction before a Canadian species was reintroduced to the park area in order to restore a predator-prey balance that had been thrown. There are now 400-450 wolves in the Greater Yellowstone area.
Grizzly Bears:Grizzly bears are 1.5 to 2 times larger than black bears, another present species in the greater ecosystem, and have larger and more curved claws than their cousins.. Grizzly bear population in the Greater Yellowstone Ecosystem is between 670 and 830, however they were considered a threatened species in 1975 due to unsustainable human-caused mortality, habitat loss and significant habitat alterations.
Mountain Lions:
There are, on record, 24-46 cougars in the Northern range of the park. Mountain lions experience frequent competition with other predators such as grizzlies and wolves, and so like to inhabit rocky breaks and forested areas that provide cover from this competition.
Coyotes grow to a height of 20 inches; wolves often grow to 34 inches and are far more massive.
Coyotes have long, pointed ears; wolf ears are rounded and relatively short.
Coyotes have thin, delicate legs, similar to those of a fox; wolves’ legs are thick and long.
LAYERS FOR COMENSUMERISM: EXAMPLE
Producers: Examples of producers are organisms that provide a primary food source for consumers. Producers are commonly autotrophs, meaning they can produce their own energy through processes like photosynthesis.
Primary: Organisms that feed on autotrophs are known as primary consumers. In Yellowstone, such organisms include the cut-throat trout, elk, moose, deer, bison, and showshoe bunnies.
Secondary: Organisms that feed only upon primary consumers ie. herbivores (carnivores) or with a mixed diet of primary consumers and producers ie. omnivores.
Tertiary: Organisms at the top of the food chain that feed only on secondary consumers or with a mixed diet of lower consumers as well as secondary. In Yellowstone, such organisms include the grey wolf, hawk and eagle.
*KEY SPECIES - WORLVES
Adaptation. Because winter are long and cols, the wildlife will endure to survive.
Grizzly bears are omnivorous and rely heavily upon nuts, fruit and roots as their main diet.
*MANAGEMENT PRESERVATIONS TO ACQUATIC RESOURCES
“Whitebark pine seeds are to a grizzly bear what macadamia nuts or pecans are to humans. The highly nutritious seeds are chocked full of fat and protein, and when available, are eaten by the thousands by Yellowstone grizzlies. But global warming has allowed bugs known as mountain pine beetles to move up the mountainsides, and attack and kill millions of acres of whitebark pine forests. As a result, the bears are forced to move down the mountain in search of different foods, where they often run into conflicts with humans and are killed." EARTHJUSTICE - "Court gives grizzlies something to sleep on"

2. The buffalo are roaming on to private property as they migrate out of the Park every year. And the government will basically herd them back into the Park. There’s a lot of disagreement over whether the government should just let the bison roam free. The argument against them roaming free is that they’ll spread the disease brucellosis to cattle, which hinges on a scientific question of how and whether the disease, can actually spread to cattle.
