The Taiga Biome is a large, naturally occurring community of flora and fauna occupying a major part of both Siberia and North America. It is usually found at high elevations at more temperate latitudes in the Northern Hemisphere. It is the largest terrestrial biome on earth, covering around 50 million acres of land (NP, UC Santa Barbara). It is known for its subarctic climate that ranges between -51 to -1 °C in the winter and -21 to 7 °C in the summer. The two main season found in the taiga are summer and winter as autumn and spring are usually very short and barely noticeable. Winter makes up around six months of the year, with only around 50-100 frost-free days during the summer. Summer is also the season during which the taiga receives the most precipitation in form of rain. The remainder is made up of snow and dew, which adds up to around 30-85cm of precipitation yearly (NP, S.L. Woodward).
The taiga is also known as boreal forest and is mainly distinguishable due to its abundance of carnivorous forests that are primarily made up of conifer or cone-bearing trees (NP, UC Santa Barbara). Three of the four most common conifers are evergreens, namely spruce, fir, and pine. The fourth conifer is the tamarack, also known as the larch, which is a deciduous tree. Other types of deciduous trees that can occasionally be found in the taiga include oak, birch, willow, and alder trees. The taiga does not feature a wide variety of plant life in comparison with other biomes due to its harsh climate; thin, acidic, and nutrient-lacking soil; and rocky terrain.
As a result of these factors, the flora has adapted to these conditions in a variety of ways including their shape, leaf type, root system, and color. One of the most prominent adapt...

The article “Hydropower as a Renewable Energy Source” (n.d.) shows that man-made dams make up seventy-five percent of the United States’ total renewable energy.
Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple
What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.
The Taiga is a biome that originates from Northern Russia that means or describes a cool large land with many conifers. Upper North America, Northern Europe and Northern Asia all are mostly Taiga. It is the largest biome and contains mostly conifers but does not have that many animals. The climate is mostly very cold and snowy in the winter and warm in the summer while fall and spring are just transition seasons.
The Taiga Biome is also known as the boreal forest. The taiga biome is the largest terrestrial biome and extends across Europe, North America, and Asia. The taiga is located near the tundra biome. It has short wet summers and l0ng cold winters. The taiga get a large amount of snow during the winter and plenty rain during the summer. The taiga is found throughout the high northern areas. The taiga makes up 29% of the world’s forest’s the largest areas are located in Canada and Russia. It has the lowest temperatures in winter. Temperatures vary from −54 °C to 30 °C throughout the whole year. Taiga soils tend to be poor in nutrients. It doesn’t have the deep, enriched nutrients present in temperate deciduous forests. Due to the cold the soil is also very thin which messes up the development of soil and the ease with which plants can use its nutrients.
Another biome in the park is their temperate forest. Temperate forests have high humidity, high levels of precipitation, and variety of trees are also included. Freshwater biomes surround the park as well.
Taiga is located in North America, Asia, and Europe. It stretches across Alaska, Canada, Scandinavia, and Russia. It is located the north part of the northern hemisphere. Taiga’s are the largest continuous biome on Earth. The Taiga is very cold because it near the top of the world. Part of this biome in North America has a landform called the Canadian Shield it takes up a large amount of this biome.
The desert biome is one of the most interesting biomes on earth. An area of land is considered a desert when it produces less than 10 inches of rainfall throughout the year. There are many different types of deserts in the world, with a very diverse group of plants and animals. It has temperatures that are generally hot during the day, and cold at night.
Another interesting fact about Lake Baikal is that more than 1,700 species of animals and plants live in the body of water. Of the 1,700 species, approximately two-thirds of those animals are unique to Lake Baikal. In other words, nearly sixty-six percent of Lake Baikal’s animals cannot be found in any other body of water in the world (Saving Lake Baikal). Species found in Lake Baikal include arctic grayling, Baikal sturgeon, and freshwater seal. Due to the huge selection and uniqueness of species in the lake many people do not know of or do not see numerous species that exist in our world. 1,700 different species in one lake is...

Climate change has been happening for many years and it continues to do so. It is a significant change in regards to the distribution of weather patterns over a given time frame such as decades or millennia. In recent times, the climate change is called “global warming” and it has been linked to certain human activities (NRC 2010). This shows that climate change is not limited to biotic factors. In a general sense, these changes have the potential to impact populations and ecosystems due to alterations in the water cycle. Climate change impacts includes too little water in some regions while too much water in other regions. Changes in precipitation patterns can influence plant physiology and thereby affect the rates of photosynthesis. Such patterns include drought in which warmer temperatures increase evaporative stress on a plant and increased rain or frequency of storms can influence water uptake by plants. Under both conditions, there is a change in photosynthetic rates. Photosynthesis allows the plant to accumulate carbon, grow and produce biomass (Niu et al. 2008). Therefore, a change in photosynthetic rates can be either beneficial or harmful to a plant. The effects of altered precipitation patterns on photosynthetic rates is significant to the scientific field because it gives insight on the shifts in plant community composition and how it affects the water availability for human and ecosystem uses (Kray et al. 2012). In addition, understanding the connection between water relations and photosynthesis with respect to changes in precipitation patterns could help with management decisions of ecosystems, where climate change indicates alterations in species composition, in water availability for wildlife and in fire regimes (L...

The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
How exactly does hydropower work, though? As it turns out, dams are the main source of harvesting energy via hydropower. There are about 80,000 dams in the United States, although not all are active producers of power. There are four main types of hydropower facilities, which all require turbines: impoundment, diversion, run-of-river, and pumped storage. Also, there are two main types of hydro turbines: impulse turbines and reaction turbines ("Hydropower…”).
