Wang Xiaotie held back the tears that were about to burst out of his eyes, and copied this snow-white little thing from the snow, and of course he didn't forget the food that the little thing found: the group of mice. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"I thought you were leaving?" Wang Xiaotie didn't know how to express the feeling in his heart, especially when he saw the food that Xiao Bu worked hard to drag back.

Even if this kind of food doesn't look delicious, there is a species that makes Wang Xiaotie shudder and can't be calm when he thinks about it. But this can't stop Wang Xiaotie from being grateful to Xiao Bu, there is nothing like having a pet that knows how to feed back, this feeling is wonderful.

"Wow! So cute! Big brother, can you give me a hug? Before Wang Xiaotie walked to the beach, Diana on the raft had already yelled excitedly.

That's the nature of a girl, and she can't resist her love for cute and cute pets, even the weak Laura, when she sees a little girl, her eyes flash with endless brilliance.

Wang Xiaotie did not refuse Diana, and of course did not agree to her. He just put the little one on the raft. Then he threw the rats to the bottom of the raft.

To be honest, Wang Xiaotie didn't plan to eat these mice. I can't swallow this thing just thinking about it. But for the kindness of the little guy, you can't throw away the food it has worked so hard to get in front of it, right?

Although it is said to be a pet, the basic face still has to be given!

"Huh~ Big brother, you're so disgusting! Why did you get so many rats back? When Xiao Bu opened his hands to Diana, disdainful of his open arms, and curled up in a corner, Diana turned her attention to Wang Xiaotie, who was throwing mice on the raft.

Wang Xiaotie......

"That's not the rat we see very often, Diana, that's the food of the arctic fox: lemmings. It is one of the main sources of food for their mouths. ”

Gwendoline is worthy of being a child who grew up in the land of ice and snow, and she knows a lot. Even Wang Xiaotie didn't see the difference between the lemmings that had been bitten to death by Xiao Bu and the rats she was familiar with.

"Sister Gwendoline, what is a lemming? A type of rat? ”

Diana has regained her previous appearance when she was disliked by Xiao Bu, and she is innocent and lively.

Wang Xiaotie climbed onto the raft again, and after sitting down, he directly waved his knife to cut the rope tied to the icicle, and the raft gradually left the beach.

This time, Wang Xiaotie's mood was completely different from just now, as if the whole family was traveling together, he glanced at the little guy lying on the first floor, took the reindeer skin, and covered this little thing.

Everyone seemed to be happy to finally escape from Iceland, which was full of dangers, completely ignoring their situation at this moment and the terrible and uncertain future in the vast sea of ice.

Gwendoline, in particular, was able to take the two sisters away from the demons this time, it was like removing the shackles from all over her body, and her mood was extremely relaxed, and she was filled with unstoppable happiness even when she spoke.

"Lemmings and rats are both rodents and rodent mammals."

Gwendoline, who was in a relaxed mood, finally began to show off her erudition, but this time Wang Xiaotie was not impatient, but while rowing and avoiding the ice floes in front of Iceland, he listened carefully to Gwendoline's knowledge lecture.

Perhaps noticing that Diana's eyes were full of question marks, Gwendoline immediately omitted all the academic introductions that followed, after all, Diana's mental age was only six or seven years old.

"Lemmings are amazing creatures, and the most amazing thing is that there are still three unsolvable mysteries about them."

Diana immediately became interested, her big bright eyes were even brighter at this time, and she immediately couldn't help but ask, "Sister, what is the secret?" Tell me, tell me! ”

Gwendoline was very pleased with Diana's expression, which was a super encouragement and high affirmation of what she was about to tell.

"The first is their ability to reproduce. These lemmings look small and cute, but their reproductive ability is the strongest among the known mammals in the world! They can give birth to 7~8 litters a year, and each litter can give birth to 12 cubs, and it only takes more than 20 days for the cubs to mature and begin to give birth. ”

"For example, if a pair of lemmings start giving birth in March, if they have a total of 7 litters in a year, 12 each, a total of 84 animals, this is their second generation, that is, sons and daughters. Assuming that each litter is 6 males and 6 females, it is 6 pairs. After 20 days, the 6 pairs of the first child began to give birth, 12 per litter, according to this calculation, the fifth generation is more than 90,000, the sixth generation is more than 320,000, the seventh generation, the eighth generation, that is, the last batch of the year can reach more than 550,000! ”

Gwendoline looked at the whole raft and grew up in surprise, and immediately became more satisfied, cleared his throat, and continued: "If you add up all the totals of this year, then a lemming couple will only need one year to breed an army of 1.6 million lemmings!" Even if half of them are removed due to climate, disease, and natural enemies, there are still more than 800,000 animals, and the density can reach as many as 250 per hectare. ”

Wang Xiaotie's eyes immediately appeared in front of the dense rats, overwhelmingly rolling towards him, and he couldn't help but hit a spirit, fortunately, Dahuaxia has long curbed the terrifying breeding of rats, and the rat plague in the early years has long become history.

Gwendoline continued: "Of course, such data is ideal, but the reproduction of lemmings is more closely related to the natural environment. If food is scarce and the environment is harsh this year, the lemmings will not have expanded to such a terrifying number. ”

"But in good years, when the number of lemmings rises dramatically, after reaching a certain density, a second mystery arises."

Diana immediately asked, "What is it?" What is it? "Sister Gwendoline said about breeding just now, although she understands that it is a very terrifying number, but without any reference, she really can't imagine how terrifying more than 800,000 is.

"For example, after a hectare of several hundred, a strange phenomenon occurs: at this time, almost all the lemmings become restless at once, and they run from place to place, making noise, and stop eating, as if the end of the world is coming."

"At this time, lemmings are no longer timid and afraid of things, and they run when they see people, but on the contrary, they are brave and unusually brave in front of any natural enemy, fearless, obviously provocative, and sometimes even take the initiative to attack, which is really a bit of a look of not being afraid of heaven and earth."

Wang Xiaotie gradually became fascinated by the listening, and sometimes he forgot that rowing was such an important job.
