"Arctic Fox"
New Aalsson is a small town in the Svalbard Islands of the Arctic. There is a cliff near the town. This is an Arctic fox foraging under the cliff. The Arctic fox gives us the impression that it is snow-white, but in fact, the Arctic fox under the polar day is gray-yellow, which forms a protective color with the surrounding environment and can effectively avoid the attacks of polar bear .
"Microorganisms living on leaves"
There are many microorganisms in the skin surface and intestines of humans. They form a mutually beneficial and interdependent symbiotic relationship with each other in the long-term evolution process. So are there many microorganisms symbiotically on the leaves of plants? We collected 10 naturally growing plant leaves, namely konjac , cedar, clover , magnolia tree, snakeberry , red-leaf heather , beef tendon grass , wenmu tree, golden-leaf privet , and 1 year-round bouquet. We separated the microorganisms on the surface of the leaves and found that the types of microorganisms on the leaves of different plants are different. What kind of symbiotic relationship does they have with plants need further research.
"Alpine Guardian"
Driving in Tibet at an altitude of more than 4,000 meters. In the rocks on the roadside, yellow plants like pagodas grown scattered in the height of rocks, which are particularly eye-catching. Its bottom is green cabbage-like leaves, and milky yellow translucent bracts grow on its towering stems. This plant is called Ta Huang , which is a plant of the Polygonaceae family Rhubarb. Some people mistakenly believe it is Tibetan Snow Lotus . Tahuang only blooms once in his life, and it takes 5-7 years of nutritional growth before it can bloom and bear fruit, and then dies. Tahuang adds a lot of color to the ecosystem on the fragile mountain rocky beach, but it stands alone on the desolate rocks, protecting the frontiers of the motherland.
"Parrot"
The red-beaked parrot (scientific name: Pionus sordidus) in my grandfather's house is a bird of the order Pyrophyte Parrot family . The genus name "Pionus" comes from the Greek word PIONOS, which means "plump". There are six subspecies in total, which are 26-30 cm and weigh 255-275 grams according to different subspecies. The bird's body is green, the head is olive green; the cheeks are olive plus a little blue; the blue will extend from the throat to the top of the chest, the chest and lower abdomen are dark olive, the back is dark olive yellow, the middle of the tail is green, the inner covered feather is red; the bird's beak is red and has a light red base; the iris is brown.
"Shape of Light"
Dingal effect occurs, light has a shape. The Tindal effect is that when a beam of light passes through the colloid, a bright "path" that appears in the colloid can be observed from the vertical direction of the incident light, also called "Jesus Light". Generally, it appears in the early morning, at sunset, or when there are many clouds after rain, and there are fog or dust in the atmosphere. The sun just projected on it, divided into strips, sometimes into large areas, which looked particularly spectacular.
