Beautiful nature

According to the National Geographic Web site reported, a new study found that termites might be able to help people to find a potential gold mine. The experiments revealed that in Western Australia, some termites in the nest when collecting underground material can be “mined” and storage of gold.
Aaron Stewart, Australia’s Commonwealth Scientific and Industrial Research Organization entomologist, he and his colleagues collected from several termite nest samples to be compared with samples from different depths in the soil nearby. The mass spectrometer detection results showed that the gold content of these termite nests above the termite nests away from the gold mining area.
“People previously recognized that such social insects from the environment to selectively capture metal,” Honorary Professor of Entomology, University of Georgia, Robert Matthews said in the message, “Some people even put forward, looking for precious metals (such as gold) potential mining sites, you can use the method of analysis of ant nests and termite nest material content.
This is precisely idea what Stewart thinks. The gold usually distributed in the depths of a few meters below the surface. It is difficult to be location. However, insects are competent to take up the task instructions. Stewart and his colleagues study, published in the recent “Geochemistry: Exploration, Environment, Analysis”.
Stewart said: “drilling is very expensive, if termites can be drilling the scope of greatly reduced, and that mining companies will save a lot of money.”
The value of the termite excrement
In a related study published in 2011 in the journal, “PLos ONE”, Stewart and colleagues want to know termites are in the body and many other animal enrichment of metal – which is looking for one of the potential avenues of precious metal deposits. Like mammals enriched in bone calcium, some insects reinforcement exoskeleton also by absorption of zinc and magnesium, and in particular their jaw portion. Zinc and other metals can increase the strength of these parts.
Stewart said, the insects will not need very good at, or toxic metals excreted. These “detox” molting, and expel small stones. When Stewart began to study the insect excretory system, has been a very interesting discovery. That is an organ of the termites excretory system through some unknown process, “to distinguish the different metal content. This is an important finding, means termite excrement metal redistribution ecosystem plays a driving role.

The scientists found that kelp is human intake of calcium, iron treasure. Every 100 grams kelp, up to 1177 mg of calcium, iron, it is as high as 150 mg is surprisingly high. So kelp on children, women and the elderly health care are important role. Another characteristic of kelp is iodized rich, general adults need to trace element, iodine, for 150 micrograms of the left and right sides, and 100 grams of kelp, but iodized element 240 mg.
Kelp contains proteins and carbohydrates are spinach several times to dozens of times. Carotene, riboflavin, thiamine and nicotinic acid and other important vitamin content is also a lot of. Kelp almost no fat and contain a large number of cellulose, algin material and a variety of trace elements.
Kelp of alginic acid sodium salt, prevention of leukemia and bone pain disease effect, to the artery disease also have hemostatic efficiency; Oral kelp, can reduce the radioactive element strontium 90 in intestinal absorption; Brown algae acid also has the effect of blood pressure; Kelp starch sulfate for polysaccharide substances, which have long blood fat function; Kelp and kelp root extract have cough relieving asthma and anticancer efficacy; Kelp contains the mannitol, in the treatment of acute renal failure, Japanese encephalitis, acute glaucoma, etc, all have curative effect. All of these, it is the kelp win “longevity food” reputation as a condition.

Bats emitting an ultrasonic wave is mainly in order to detect the orientation of the food. They are used in the acoustic frequency is usually as high as 40,000 to 300,000 hertz, Bordetella 1 to 3 mm. Almost stationary, small objects bats for food (ie eating insects parked in the trees or fruit, berries like bat species), foraging the use of sound waves is relatively low and constant frequency, approximately 150,000 Hertz . Bats prey in flight not only to determine the orientation of the prey, but also measured the movement speed of the prey, so they have to make good use of the frequency of changing sound information. Insectivorous bats often their bodies upside down in a tree or on the cliffs, their mouth is constantly rotated in all directions, issued 10 to 20 per second signal, each signal contains 50 acoustic oscillations, starting frequency and the end of a frequency of 90000 Hz and 45000 Hz, respectively, so that the two different frequencies to appear in a message.
Bats by measuring the positioning signal wavelength echo sound waves change to the positioning of prey in flight orientation. Prey head flying, bats as prey compressed degree of compression by a length shorter the reflected sound waves, the speed of prey flight speed and reflective acoustic wavelength is proportional to’ll receive. If the prey and bats reverse flight, the received echo wavelength larger, faster, hear the echo frequency lower.
Bat echoes sounder with high accuracy. The different textures of objects on the reflection of sound waves are not the same, flat and smooth objects reflect sound waves best soft rough acoustic attenuation, bats can escape from the area of the same cloth, plywood, and sandpaper distinguish.
Echo love fish bat detector can not only work in the air, even the strong penetration of water. They are close to the surface of the water flying, and send a signal to the water. Arguably sound signal may only be partially reflected back from the surface, and most of the echo may be dissipated in the air, in addition, contains 80% water of the fish with water acoustic Laid wins very close, the sound of the bat is almost impossible from fish reflected back on the body. But in fish swim bladder full of air, which can help the bats busy. So much bat through the swim bladder to detect the exact location of the fish, it would be better to say is the swim bladder betrayed fish hidden in a “spy” in fish.

Humans can in the similar need, across the country, race, skin color restriction, help each other to love each other. Among animals, also have such a warm care, it goes beyond the boundaries of different RACES, more reflect the “international socialist spiritual” essence. When the lonely time to take care of each other to call the lonely, when need a mother’s love of surrogate mothers feel care, touching painting pictures, show us the positive emotion, in fact among animals than we imagine more true and warmth.

This first lived in Africa lion shape like a lion, is actually a female lion, the first special lions have thunderous cry and thick and slippery mane, these are a lion special mark. But through a closer observation, you will find that it is actually a female lion, leading to the “male and female thing” is the root cause of hormone imbalance.
Experts say the lioness variations may occur in the fertilization, or embryo in the womb has been tampered with. Big cat protection organization also pan pull (Panthera) chairman Luke hunter said, if it is the former case, the sperm is likely to be deformed, and most of the mammals embryos in the gender is determined by the sperm, There are a lot of possibility is during pregnancy, embryo came into contact with higher than normal levels of the male hormone, which can lead to genetic abnormalities. But either way, a lion may have no ability to bear children, survival is no problem.
This only a lion special signs that lion group of other members to it for many years a mile, it had to wander alone in the delta plains. Local wildlife guide report said recently, the other lion has accepted this head different lioness, finally it is expected to reintegrate into lions, and even become lions “noble”. Because if the other lion see it as a lion, it can better resist foreign invasion.
Hunter told national geographic interview, if a lion behavior as males, that will be very interesting. There are two head also abnormal serengeti lion, they have no thick mane, but size almost and lions, and in order to fight for the territory, they will and a lion fight, because they think it is a lion!

Lions captured a number of bison. They all herded into a cave, ready to enjoy. These bison almost completely pomp king of beasts terrorized guts, they are just helpless sigh, silence hanging Qinglei. They think the lions eat cattle, like bison grazing, is perfectly justified, reasonable things, God, since it is God’s plan, then, but also too much to consider what is it?
However, a young bull, went so far as to use its brain. The secret is to have a unique claws and giant teeth. It is noted that: powerful lion and elsewhere, does not excel even more weak at the belly of the lion - that places a piece of white fluff. The Bison secretly resolved to compete for themselves as well as the entire herd breath. When an arrogant lion hole feeding it aimed at the opportunity, ramped up the effort, arrived to go to the belly of the enemy with lightning speed, goes as far as the lion’s belly pierced. The only bisons have also been a few lion revenge.
Head heroic bulls Pro last breath, said: “I see the results, how happy my heart! So proud because I can use the blood of a lion peer and descendants wrote this epigram:” As long as force can crush the king of beasts myth of invincibility! ”
People are pulling a lion cage fled to the mountains. When the fen cut roar when many beasts around in horror stampeding only an old cow day smell the grass, still hum. Later, other cattle questioning why there is as big as the courageous, the cow said: ”I have noticed that the lines armed has been fully discharged, so it roar again, but hides momentum.”
No powerful strength backed by public opinion, despite the aggressive, is not so formidable.

As long as quickly expel elk, you will make them feel fear. A new study shows that when people are around, in Alberta in Canada, elk will be fearer, because they put human beings as predators. In the course of a year, the researchers figure out the dynamic relationship between humans and wildlife by observing Alberta elk. On public land, private land, and protect land, the researchers tracked 424 deer and 870 individual elks. When the elk live their own lives, the researchers observed these animals in the safe distance and recorded their behavior, such as: eating, grooming, and rest and so on. The scientists found that the human caused the greatest degree of interference to elk, even larger than their natural enemies of interference. Elk predators include wolves, cougars and grizzly bears. When elk encounter human, especially when encounter human in these public places allowing hunting and allowing driving vehicle, these animals will suddenly switch to the vigilance mode, glanced around to see if there is danger exists. Only every two hours over a car is sufficient to trigger the elk vigilance behavior, which would reduce the consumption of time, the doe will turn in a sub-health state, is not conducive to calve. “The role of the human to elk is just the same as natural enemies, and there may be more frightening than the natural enemies,” the behavior of the University of Alberta ecologist says Simone Seuti. The description of observed elk research is published in the Public Library of Science – Integrated and Se Youti is the first author of the research paper. He said: “The first consequences of this tension are the reproductive success rate of female elk may decrease.” Seuti and colleagues plan to study the different effects of different human behavior (such as: hunting and hiking) to elk behavior, they also plan to test whether these results also apply to other sensitive species, may also explain the reduction in sensitive species like reindeer.

Humans and pests had done countless contest, the use of natural enemies of pests to insect pest is one of the most effective methods. Aphid parasitoids as natural enemies of aphids, for mankind to wipe out the world’s great pests – aphids, has achieved a lot.
Aphid parasitoids Insecta Hymenoptera the aphid parasitoids species have all kinds of this section are budworm parasitoids. Aphid parasitoids be mainly its eggs uniforms aphids. Annual spawning season, female bees mating with drones, but regardless of mating or not the female bee can lay eggs. The female spawning bees ovipositor stabbing the back of the abdomen aphid eggs into the aphid body, this aphid parasitoids eggs on aphid body parasitic down. Parasitic budworm eggs develop into larvae, where it stimulates the aphids, aphid eating increased. Weight increase, vicious expansion of the body, and finally turned into a valley granular brown or reddish-brown dead not stiff aphid. There is another case, some bee larvae in aphid body endocrine insect hormones, excess hormones affect the normal development of the aphid, abnormal metamorphosis, or early death or total grows up, and eventually died at aphids. An aphid parasitoids spawning hundreds of tablets, each one eggs are fired the aphids “bullets”, and almost “eyesight”
The highest hit rate, according to someone’s testing it is up to 98%. Contemporary agriculture and forestry, the large scale introduction of aphid parasitoids to pest control the aphid parasites has become a strong force to eliminate aphids.

In nature, most of living beings need gender mating to breed offspring, but there are very few species have asexual reproduction capability, most belonged to parthenogenetic reproduction, it is mating without males, females have fertility, is commonly known as self-cloning, such as snails and water fleas, have the ability to self-cloning, but the lobster does not have this ability. In Germany, there is a kind of artificial breeding of mysterious lobster is found to actually have asexual reproduction capacity, which made local scientists deeply shocked, but also expressed deep concern about this lobster strong vitality and abnormal cruel, once enters the natural world will bring disaster to other species of lobster.
This kind of mysterious self-cloning lobster is all female, is very popular in around the freshwater farms inGermany, fortunately, it has not yet been found in the wild waters lobster. According to the scientists said, once they get into the wild ecosystem, will cause a huge threat to be local lobster of Europe.
According to the scientists in Humboldt University, Berlin, Germany, said, this mysterious lobster is called “Marmorkrebs”, body is hard, and vicious temperament, it may be associated with a species of North American, but scientists cannot be sure that where they are originated. Humboldt University zoologist Gerhard Schultz said each female “Mar-morkrebs” Lobster six months can be self-propagating least 20 crayfishes, some are even up to nearly hundred. Due to their strong reproductive capacity, coupled with fierce combative, enters the wild state will kill other species of lobster. In addition, this lobster has a strong ability to adapt to the environment and pathogen resistance, with its own germs, but rarely the disease, but other species of lobster is infected, it is very easy to get sick, even popular lethal “lobster plague so scientists call this lobster breeding farms, not on the rivers and lakes. Dr. Schultz warned: this mysterious lobster farms in Europe are very popular. People have farmed their fertility antiviral ability, and delicious. Such European freshwater lobster ecosystem is a huge threat, even if there is only one to enter the field, or a few years, their numbers will reach unwieldy, other lobster does not have the ability to compete with them. ”
Europeans like this lobster meat, nutritious and delicious, so it is popular in Germany, each lobster is actually sold for 5 euros.

Taste of chameleon wonderful ability to transform the body color in different environments, the following will talk about the pride of the plant kingdom – Red Gilligan grass, it can change flower color, thus known as the “Chameleon” in the plant.
Red the Gilligan grass grows in the Faun Mountain in the southwestern United States. Their flowering season is in each year from mid-July to early September, will fill the fields full of this spendthrift slender flowers. Quite interesting are the small size of the hummingbird and an insect named Hawk moth served as the pollinators media of the Red Gilligan grass. The powder is pollen, and it is a male, growing in the stamens anthers. An anther frequently can grow many single-celled pollen grains, and pollen grains are able to happen passage, must have a chance (by wind or animals) to fall down onto the stigma of the pistil. So why the obscure red Gilligan grass can attract hummingbirds and insects for pollination? Its charm is its magical “discoloration flowers”.
It turned out that every year in mid-July the flowering phase of Red Gilligan grass just starts. Coincides with hordes of hummingbirds came to the Faun mountain foraging. At this time, the majority located in the higher elevations of the Red Gilligan grass burst into gorgeous and striking safflower, in order to attract the attention of the hummingbird. Suck sweet nectar, hummingbirds are also pollination for Red Gilligan grass, flowers unwittingly pass powder. However, to the end of August, the climate is gradually getting cooler, hummingbird likes the warmth often flies at a lower altitude mountainside to be pollination for Red Gilligan grass. Since then, original red living in high Gilligan uncharacteristically, no longer burst out of the bright red flowers, instead of pale pink flowers. The longer the time, the lighter their color, until at the end of August, the color becomes white. According to scientists statistics, at the end of August, Red Gilligan grass grows at high altitudes, are about 40% of pale white flowers. What are the benefits of corolla becoming color from red to white? It turned out that it is in order to attract the second pollinators – hawk moth. Because the hawk moth is active at night, light white flowers at night can more arouse the attention of the hawk moth to make pollination easier.
Studies show that by the end of August, those still grow bright red flowers, red Gilligan grass pollination rate is only 29%, while the light-colored flowers of Gilligan grass changing color the red pollination rate is as high as 53%. Obviously, timely change colors greatly enhance the reproductive success of the Red Gilligan grass.
The red the Gilligan grass discoloration mechanism is still no satisfactory explanation, has yet to be further research of botanists.
