Zhang Jinjie is no longer lazy, and he is about to chase Yang Shubao when he jumps.

Yang Shubao turned around and ran: "You can't catch up with me, there's no way, I'm just so strong, lala......"

How could Zhang Jinjie catch up with him? After chasing him for a while, he stopped and gasped.

As soon as he stopped, Yang Shubao ran over and sprayed him again.

Zhang Jinjie was scared, covered his face and ran into the office.

Yang Shubao shouted at him: "It's okay, this thing is not dirty." This is a fruit, which can be eaten. ”

Zhang Jinjie scolded angrily: "I believe in your evil, get out of the calf!"

Uncle Yang Baojiu occupied the magpie's nest, sat on the recliner and sighed soothingly with his hands on his pillows: "Comfortable." ”

He wanted to take a sip of beer, but when he saw that Zhang Jinjie had already drunk half of it, he put it down in disgust.

The light rain was falling intermittently, which was completely different from the rainy season.

As soon as the rainy season starts to rain, God turns on the faucet and it rains heavily.

Now the light rain is like an old man peeing, the prostate is not strong, and it stops for a while, and then it quickly goes back to a while.

The rain lasted for two and a half days, and after the rain stopped, the temperature dropped a little, and South Africa officially entered winter, and Yang Shubao had to wear a long-sleeved T-shirt to protect himself from the cold.

In the past, the vegetation on the grassland was greener and more lush after rain, but now it is still yellow, but the water of the creek has risen, and the wetland area has expanded a bit.

Yang Shubao went to inspect the wetland and saw giant frogs bouncing on the shore.

He went to look at a patch of sand, and there were some broken egg shells in the sand, and the crocodile eggs he had buried earlier had hatched, and the baby crocodiles had already come out.

However, Yang Shubao couldn't find them, so he should have hid them in the muddy water.

Don't look at the ferocious six relatives of crocodiles when they become adults, they are still very tender when they are young, wild dogs, hyenas, fierce eagles, crown eagles and other natural enemies will always look for them, it is not easy for them to grow from a small delicate flower to a fierce beast, and the survival rate is very low.

The frogs had been bouncing around the shore, and Yang didn't know what they were doing at first, but as he approached the edge of the wetland, he realized that something was wrong: the frogs had laid eggs.

Frog eggs hang one by one on the edge of the wetland and in the weeds along the shore, where small crocodiles are foraging for their eggs for food, and giant frogs are driving away baby crocodiles to protect their offspring.

Seeing these giant frog eggs, Yang Shubao was very surprised: Aren't frogs all laying eggs during the transition of spring and summer?

Worried that he had misremembered, he went back and found a copy of "Research on the Reproduction of Vertebrates in Africa" and read it.

There are books about the breeding of giant frogs, but little is known about the mating system of giant frogs.

Giant frogs are known to lay their eggs on vegetation at the edge of streams and wetlands during the dry season in Africa, from December to April.

Their spawning grounds are also complex, from regular streams and wetland edges to steep rock walls and river banks, where male frogs then fertilize their eggs.

Now what Yang Shubao sees are fertilized eggs, each with a diameter of half a centimeter, which is already a large size among the eggs of frogs, but it is worthy of the burly figure of a giant frog.

But the season is not right, although the giant frog is not the spring and summer transition season that Yang Shubao remembers, it should not lay eggs in this winter.

Yang Shubao checked on the Internet again, and finally got the answer that it was related to global climate change.

As carbon dioxide emissions continue to increase, the global warming effect is becoming more and more serious.

According to the research of geographers and meteorologists, the earth should enter the Xiaoice period now, and the overall temperature of the earth should fall.

This is not the case, the temperature is not falling, but is rising, and the entire Arctic ice sheet is almost melting.

This causes a lot of trouble for animals and plants, and the abnormal ovulation behavior of giant frogs is related to this, presumably because the temperature of this month is suitable for their breeding season, and after coming to the reserve, they eat food containing the fountain of life, causing them to enter the breeding period again.

The Tree of Life has the ability to promote the reproduction of animal and plant races.

The information also describes the living habits of tadpoles, the offspring of giant frogs, and Yang Shubao paid special attention to one of them: tadpoles are purely herbivorous species, and they only eat river moss.

Yang Shubao couldn't help but rub his temples when he saw this, he knew that river moss grass was an aquatic plant that resembled moss, moss, algae or lichen, without any stems and leaves, and was quite common in the river waterfall belt in tropical and subtropical Africa.

He was afraid that his memory would be wrong, so he took out a copy of "Aquatic Flora of Africa" and looked it up, and deliberately found the river moss and looked at it carefully.

Noting the appearance of the river moss, he and Nicole went to the river to look for it.

Nicole's college major is closely related to plants, and she also knows about river moss, so as she walked to the river, she asked, "Are you sure you want to find it?" I want to say that there should be no river moss grass on the grassland, especially our small river here, its environment is not suitable for the river moss grass to reproduce. ”

Yang Shubao said: "Let's look for it, maybe there will be?"

Nicole explains, "You may not know, but river moss is amazing, they love water and hate it. They live in water, so they love water, but they are only exposed to the air when the water level drops, and then they can flower and sow seeds, so they hate water again. ”

"I mean, if river moss grass lives in a river, it must live in a seasonal river – a river in the rainy season and a dry riverbed in the dry season. This small river is not a seasonal river, you see it does not have dry periods. ”

Yang Shubao still said: "Let's find it." ”

He couldn't tell Nicole that the river was actually a seasonal river, at least in the past, and that the reason why the river didn't have a dry season this year was because the Tree of Life released the rainwater it absorbed during the rainy season during the dry season.

But Nicole is right that the river moss is a plant that only blooms after the water level has dropped and exposed to the air for a certain period of time. Then in the dry season, their seeds are scattered on the rocks after they grow, and in the rainy season they germinate when the rain is abundant.

Miraculously, the seeds of river moss grass are sticky, sticking to rocks and birds' feet before spreading to new places.

River moss grasses have a unique appearance in that they have no normal foliage, only highly metamorphosed banded phyllodes that will have secondary branches later.

Among them, the banded phyllodes are used to absorb solar energy and convert them into bioenergy, while the secondary branches are used for flowering and seeding.

They walked to the river, and when Ma Tsai saw it, he shook his head and ran up to ask for caresses.

It watched the two of them come together, and thought they were here for a walk, and the underage hippopotamus likes to take a walk.

Seeing Ma Tsai coming, Yang Shubao hurriedly prepared to play with him.

The hippopotamus grows so fast, and the horseboy is already bigger than a lion.

But the lion king was not afraid, and when he saw the horse showing his head, he licked his lips and wanted to eat meat.

Hippos have a lot of fat on their bodies, and carnivores like fat the most.
