The forest floor is littered with leaves and decaying vegetation. Decomposition by bacteria and molds is rapid, and nutrients are quickly recycled into new plant growth. This is due to the poor soil quality in tropical rain forests. Nutrient layers only exist in a thin topsoil that is replenished by dead plant and animal remains. However, there are rain forests that have rich soils; these are typically areas of volcanic activity where volcanic soils comprise a nutrient-rich base for forest growth.
The precipitation can fall in the form of rain or snow, with snow becoming more likely at higher elevations. The average annual temperature is above 0� C, largely influenced by the nearby ocean. The warmest of the temperate rainforests may have average annual temperatures around 20� C. Plants- Indian Paintbrush – Castilleja, Bigleaf Maple - Acer macrophyllum Animals- Banana Slug, Ariolimax columbianus, Clark's nutcracker Nucifraga columbiana, Blue grouse - Dendragapus obscurus timber cutting is the number one threat to these forests, The silt, and the nutrients and pollutants it carries, are a threat to near shore marine organisms as well as freshwater organisms in the river itself, and the area the silt is coming from Temperate Deciduous Forest Location – North America, western Europe, China, Japan, Korea Australia The latitude range is anywhere from 23 ° north to 38 ° south. Most deciduous forests have mild summers averaging about 70 °F. Winter temperatures are fairly cool with an average temperature of a little below freezing.
These three things plus the sun's heat determine where rain falls on the planet. The sun shines almost vertically on the equator year round, but it shines on the poles at a steep angle. There are two consequences. A beam of sunlight ten square feet shines on about ten square feet of Earth's surface at the equator, but it covers more than twice that area near the poles. The sun's light and heat are less concentrated at higher latitudes.
Habitat: * The Chinese water deer can often be found living in China, North Korea and South Korea. They were also introduced and became wild in England and France. * They prefer habitats characterized by shrubs and small trees, and are commonly found around rivers, streams, swamps, marshes, reed-beds and coastal plains, often in tall protective reeds and grassland. Contribution to Ecosystem: * Chinese water deer tend to graze in hearty habitats such as marshes and reed beds and may also eat root crops when other food is scarce. This helps maintain the growth of plants and other vegetation.
The greatest threat is to the deserts of the American Southwest - from Texas to California - and Mexico. These deserts are home to 114 native species of Opuntia, about 80 of which are flat-padded species vulnerable to the cactus moth. In the difficult desert environment, prickly pears are a nutritious and reliable food supply for many wildlife species, including deer, javalina, Texas and desert tortoises, spiny iguana, and pollen-feeding insects. Prickly pears provide shelter for packrats - which in turn are eaten by raptors, coyotes, and snakes; and for nesting birds including the cactus wren and curve-billed thrasher. The cacti also are nurse plants, under which other desert
The main characteristics of this class include: fur/hair, mammary glands that evolved from sweat glands to produce milk for their young, a diaphragm to aid in respiration, they are endothermic, and bear live young. They belong to order Artiodactyla, which have the characteristics of even-toed hooves and are herbivorous (Carter 6). This information supports my argument in many ways. Giraffes are perfect for surviving in the African savannas because they have a camouflaged coat with patches of different sizes and colors to help them hide from predators, and have a fringed tail to help keep flies and other pests away. Their hind legs are shorter than their front legs, with tough hooves protecting each foot as well.
The Mbuti of Northeast Zaire Efrem Terrell ANT 101 Prof. Robert Moon Nov 20, 2011 The Mbuti of Northeast Zaire The Mbuti are Bantu-speaking hunter-gatherers living in the southern part of the Ituri Forest of the northeast part of the Democratic Republic of Congo (former Zaire). While their traditional way of life is often described as centering on hunting and gathering of wild food resources, the Mbuti rely for a large part of their subsistence on cultivated foods acquired in exchange from village-living horticulturalists. Most cultivated foods are acquired by Mbuti women, who in return provide forest products for the villagers or work in the villagers’ gardens. This type of reciprocal relationship dates back hundreds and possibly thousands of years, and occurs among all Pygmies in Africa except for those who have recently settled in villages and begun to grow their own food (Cultural Survival). The Mbuti are considered to be a foraging group of people or better known as hunters-gatherers because they depends primarily on wild food for subsistence.
The climate in Denmark is very consistent throughout the country mostly because it is a relatively small and there is not much chance for the weather to change. Because it is so far north, this means that in the late months of the year such as December, the sun will only show itself for 7 hours, however in the summer the sun will appear for a whole 17 hours. The amount of sun that presents itself throughout the year makes it so that the seasons are very different and the temperature changes dramatically from winter so summer. The average temperature in the month of July is approximately 18 degrees Celsius (64.4 Fahrenheit). As this is only the average temperature it can get to be between 26 and 30 Celsius (78-86 Fahrenheit) during the month of July and throughout the summer.
The tropical climate is characterized by constant high temperatures. All twelve months have an average precipitation of at least 60 mm (2.4 in), whereas in the savanna climate, the annual precipitation is contrastingly 25 mm. In the dry climates (group B) contains: arid and semiarid climates. Desert regions on the West coast are much cooler, due to the nearby presence of cold ocean currents and frequent cloud cover. The mesothermal climate (group C) consists: mediterranean, humid-subtropic, and oceanic climates.
