The lynx belongs to the family felines. The coat is more or less mottled with yellow-brown base color that brightens the winter. The tail is short with black lace. On the ears is black ear tufts. The tip of the tail and ear tufts reinforce the ears and tail posture, and making the lynx's body language clearly.
A timid forest animals
Lynx are shy, solitary forest animals that thrive especially well in rocky and steep terrain. They hold territory, areas that they defend against other lynx. The territory is characterized by urinary markings. In northern Sweden, the territory up to a square miles large.
The main prey is rabbits, but lynx are adapting their eating habits after the asset. In the reindeer herding areas eat the most reindeer, especially during the winter. In southern and central Sweden are deer usual prey.
A lynx chasing carefully sneak up on prey. When the distance is 20 to 30 m are attacking it instantly. Larger prey is killed with a bite to the throat, less with a bite to the neck. If the attack fails, give lynx soon the hunt, waiting instead for the next chance.
The mating season is in March-April. In May-June the female gives birth to one to four kids that she alone is responsible for. The cubs follow their mother for nearly a year. From her, they learn among other things, to hunt and kill prey. When the chicks are less than two years they become sexually mature.
Sensitive to hunting
At the turn of the century there were almost no lynx left in Sweden. Over a period of PROTECTION BY LAW 1927-1942 recovered strain, and at the beginning of the 1980s there were lynxes in almost the entire country. But then the number has decreased and in 1991 became the lynx once protected.
Over-hunting is probably the reason for the decline. Sarcoptic mange, which is shown to also affect lynx, may also have played a role.
Today, there are lynx probably in all regions except the island of Öland and Gotland. But south of a line-Värmland, Dalarna-Gastrikland born, few, or no, kids.
Although the lynx is a protected species, there are illegal hunting, especially in areas where snowmobiling facilitates the tracing.
An ecosystem can be anything from a COWPAT to the entire globe, but generally refers to the one between the large area such as a lake or forest.
A food chain is an interaction in nature between plants and animals. This chain of events is found in different forms in different places in nature. But it is always constructed in much the same way.
How can there be in a lake:
Arrow 1 sun causes it to grow algae that are eaten by plankton.
Plankton The animal was eaten up by a mosquito larva.
Arrow 2 mosquito larvae are eaten up by a bleak.
Arrow 3 bleak eaten up by a pike.
Arrow 4 pike is eaten up by an osprey.
It always starts with the sun and its life-giving energy.
The lake is small plants called algae. The algae use the sun's energy to produce nutrition in the form of sugar. They are called producers.
The algae are eaten by zooplankton that get called first-hand consumer.
Plankton animals in turn become food for the aquatic insects, such as a mosquito larva. Mosquito larvae are then called for second-hand consumer.
Mosquito larvae can in turn be eaten by a bleak.
Bleak then called third hands-consumer.
Bleak can then be devoured by a predator, we call for the fourth hands-consumer. It may for example be a pike.
Predators do you call all the animals that eat other animals.
The animal is higher in the food chain might be Osprey or human. They call us the top consumers. Top Consumers will not be eaten by anyone.
The ecosystem is often illustrated by a "nutritional pyramid".
Nutrition pyramid shows the total biomass of all living plants and animals. Biomass is therefore the weight of all living matter and can either be calculated in fresh weight or dry weight.
The lowest level of the pyramid is occupied by the plants that are ecosystem producers and also the only organisms that are photosynthetic (Energy + carbon dioxide + water = sugar + oxygen). This means that they build up on themselves of simple inorganic substances, namely carbon dioxide, water and minerals for absorbing solar energy. In the air are carbon dioxide is available and the water is taken over teams up through the roots in the ground. In connection with the water absorption so are also minerals as ion and salt up. After the plants thus the herbivorous animals that make up the pyramid's middle block. These are in turn ecosystem first consumers. Top of the pyramid is made up of predators or, as I call them, the top consumer, and the lowest total biomass.
Decomposers are mainly bacteria and fungi, but there are many more animals that belong to this group. The material of the dead animals and plant cells return to the ground just because of decomposers. The end product of their activity is carbon dioxide, water and minerals, which after decomposition becomes available to the plants again. Thus, I can finally be concluded that it is decomposers which completes the cycle.
Only 14% of Earth's land area consists of rainforest. It is important for us in many various ways. We eat such as bananas, avocados, pineapples, oranges, lemons, cocoa, coffee beans and much more that originally comes from the rainforest. Medically speaking, it means the rainforest too much, about a quarter of all medicines we use are extracted from plants found in the rainforest.
A rainforest usually have an annual rainfall of mins 1 500 mm, usually a much greater precipitation, which is distributed over at least 9-10 months a year.
One section rainforest in two different varieties, tropical rainforest and temperate rainforest. Tropical rainforests are found in eg South America and Africa. Where there is a temperate climate and moist westerly winds during most of the year there may be a so-called temperate rainforest. It resides on North America's northwest coast, Chile and New Zealand.
In the rainforest are some animals over others, both literally and in the food chain. At the bottom of the rainforest, the river, live fish and plants. A known fish is the dangerous piranha. Above the river, on the ground live among other wandering ant, antbird and various plants. There already sees signs of the food chain again. Ant eats plants and small animals, and then eat antbird up wandering ant. In the middle of the rainforest, there are animals that orchid bee feeding on orchids, there are also tree frog that eats including orchid bee. Higher up in the rainforest canopy, live birds and other flying creatures, monkeys and of course, small caterpillars and animals in the trees. High up in the treetops live the great king vulture.
When you get an overview of the food chain can also get an idea of how the enrichment of the animals appear. It starts at the bottom of the food chain, on the ground, underground or in the water, spreading even to the largest consumer. When the producers, plants, or phytoplankton, absorb nutrients from the water that is poisoned as stored toxins in the tissue and when the next animal, primarily consumer, eating producers also get those toxins itself that are stored in the tissue, and so it goes all the way up to the standing top of the food chain. By that time, the toxins kocentrerats so much so that the predator can have problems with fertility and may even die. This is a problem, though certainly not the largest.based on 37 ratings Ecology
