Chapter 316
Large pastures and dense mountain forests are intertwined, low mountain bags, towering cliffs and valleys, undulating, staggered, is a unique landform in the heart of the volcanic island.
Shallow said: "The vast activity space, endless forage, and no natural enemies, this is really a paradise for herbivores."
"It stands to reason that it should explode the island!"
"What is Bakugan Island?"
"Have you ever raised guppies?"
Guo'er said: "Raised, very good-looking, but it is easy to give birth to many babies."
Shallow said: "I also raised it, and then I knew that the mother fish would eat the child, so I didn't raise it."
Lu Zhe nodded: "Have you ever thought that the mother and son of guppies cannibalize each other, but they will not be infected with prions like humans, just for the group to reproduce better!"
Shallow was a little frightened: "Mother eats baby, is it for the reproduction of the group?" Sounds incredible!
"It's a bit hard to accept, though. But the actual situation is that the smaller the fish tank, the more obvious the behavior of the mother fish eating the baby, and the larger the space, the less obvious this behavior is. What is it not to fight for the limited space for a living baby? Shallow
wondered: "Then why are there so many raw points in the first place?" "
Of course, no one uses the benefits of TT with them."
Lu Zhe said: "As a fish at the bottom of the food chain, strong reproductive ability is also the foundation of reproduction. It only means that they have not evolved to control the number of reproduction according to the environment.
"That is, you don't usually eat all the small fish, do you?"
Lu Zhe nodded: "To raise guppies, when it is almost time to give birth, put them in a separate small tank, and forget to catch them the next day, some of them are eaten by the mother fish, but there will always be a few small fish left."
Guo'er recalled: "Yes, yes, my fish is like this!"
"I learned that if you quickly fish out the baby fish every time and raise it, in a few months even if several fish tanks in the house will be full."
"That's right, uncontrolled fertility in a limited space, the final result is a bursting cylinder!" Then the environment in the fish tank deteriorates, the oxygen content decreases, the bryozo grows, the water smells, and finally all the fish die! "
Shallow and Guo'er looked at each other, as if they understood the true meaning of fish farming in an instant.
"Okay, guppies are finished talking, let's go back to the topic just now, in the case of good living conditions, sufficient food, and not enough terrible predators in the territory, I am afraid that they will multiply in large numbers, so that the living environment will collapse, and eventually cause species extinction!"
"However, that doesn't actually happen here."
"That's why I'm wondering."
Thinking lightly, he nodded and asked: "Lu Zhe, I remember you said that the East Island Bison, when our troops landed on East Island, more than 400 bison survived on that small island of only 1.7 square kilometers, but the living environment of the island still did not collapse.
"That's because of the water!"
"Water?"
"That's right! There is a freshwater pond in the hidden area of the hinterland of East Island, but it is the only source of water for East Island, supporting the drinking water of all the animals on the island!
"Is it because there is enough water in this puddle that the island has not collapsed?"
"Quite the opposite! The pond is small, inconspicuous, and often runs dry. Therefore, when the dry season comes, a large number of bison will die due to thirst, and cows will also reduce the reproductive success rate due to lack of fresh water, so that the control of East Island bison population will not exceed the critical point of Exploding Island. Shallow
sighed: "I know now that sometimes the scarcity of survival resources is a favorable condition for reproduction!" This turned my perception of wildlife and biology upside down.
Guo'er said: "But our island is not short of water sources, there is a big lake upstream, and there are so many shoals downstream, enough for them to drink!"
Lu Zhe turned his head with a solemn face: "So, the question arises: what factors are controlling the number of bison and wild boar?" "
It's terrifying to think about!
The two girls felt goosebumps all over their bodies.
"Could it be... Is it a red-haired gorilla?
Lu Zhe shook his head: "Orangutans, like bears, although they are omnivores, they love to eat fruits, gnaw bananas, can also eat birds, catch bird eggs, it is necessary to take thankless efforts to catch cows and pigs, the risk factor is too high for them."
Guo'er said in horror: "It won't be a tiger, a lion, a leopard, or a wolf, right?"
"It can't be either!"
Lu Zhe thought for a moment and said: "These kinds of animals have strong hunting ability, catching cattle and wild boars is the same as playing, if they really appear on this island, they will breed in large numbers and hunt plant eaters madly." The volcanic island is too small and shallow in depth, unlike the plains that allow herbivores to migrate and detour to avoid predators and then return to breed! A predator 'explodes' in several balance games may completely exterminate bison, boar, deer and dolphin, and then become extinct themselves.
"So what would be the factors that control the numbers of these herbivores?"
Lu Zhe thought for a long time and shook his head: "Frankly speaking, I don't know, I can only give the credit to the clouded leopard crocodile python and their brothers first!" "
Do you want to keep flying?
Lu Zhe was worried that the battery was not enough, did not want to risk it anymore, and began to fly back.
When I returned to the surface of Mirror Lake again, the fog was still thick, but I found a strange sight from another angle.
The fog in the northwest of the lake is particularly thick....
Faintly, there seemed to be mist coming out of one place, blending with the mist in the air.
Lu Zhe wanted to go down and take a look, but it was also at this time that the aircraft sent a message of tight power again.
Decisively start the automatic return trip.
Shallow regret sighed: "It's a pity, I still haven't found Haiyan and Yongqiang."
Lu Zhe looked open: "We know the habitat of the bison group, let's go and catch two more back!"
Guo'er also said: "But the other cows and we don't know each other, Haiyan and Yongqiang have some emotions."
"If you don't know it, you don't feel guilty." We still lack a cauldron, otherwise it would be cool to make a whole pot of beef.
"You're really not going to find Haiyan Yongqiang!"
"It's not that you don't look for it, this kind of thing is still casual! Maybe I'll be back one day. However, the shallow taste of lactic acid bacteria yogurt is still good. He
blushed slightly: "If you like it." At
this time, the flying machine flew back on its own.
"How's that, do you still fly around?"
"I want to fly, it's nice to look around, but it's too laborious!" Get a hydro generator?
"The bicycle generator is on the ice sister's side, and the flow speed of that mountain stream is too slow to drive the generator." The canal on our side is okay, it's better to go to Sister Bing's side and take things over. Shallow
thought for a while and said, "Then let's go to Sister Bing's side to take a look!" "
