Biologically speaking, a species that spreads over an area that is not its natural habitat. invader is named. The largest land mammal invasion in history is in a much smaller and more endearing species, despite our species’ great interest in spreading everywhere and depleting every resource: in rabbits.
An English nobleman who participated in the colonial movements hunting passionHaving little knowledge of rabbits, zero knowledge of the habitat of the Australian continent, and possibly inability to resolve the issue of exponential growth, posed a serious problem of rabbits that persists even today. How Does? Let’s examine it together.
When we look at the history of the world, we see that from time to time, countries have entered into a struggle with various animals. Once upon a time, China waged war against the sparrows, and Australia, on the ostriches, and lost. Probably the worst defeat Between Australia and rabbits came in the struggle.
on the world today 65 countries It gained its independence from British captivity. One semester British Empire managed to spread all over the world. It is a known fact that they try to establish their own culture wherever they go.
One of the biggest hobbies for the British is hunting, which makes people say it’s a hobby. Wherever they go, the colonists want to continue hunting. For this reason, in the 1800s, Thomas Austin told himself 13 European Rabbits It wants to be sent. He spends his time hunting the rabbits he releases in his vast fields.
The most told story about exponential growth is, chessboard and wheat is the story. In the story, a sultan wants to give an award to someone, he asks the person who will receive the award what he wants. The person who will receive the prize wants to put 2 times as many wheat grains as the previous one on each square on the chessboard, with 1 grain of wheat in the first square. After a point, wheat doesn’t grow, 1-2-4-8-16… at the end of the job billions of wheat must.
A similar situation exists with rabbits. at first 6 pairs of rabbits, if these rabbits have an average of 4 puppies per year and give an average of 3 puppies each time, the number is 72 puppies and 12 adults in a year. increase to 84. A year later, the same process is started, this time with 84 rabbits. Let me not tire you with calculating the result: the number of rabbits living on the continent in 1920 over 1 billion had happened. (Exponential calculation logic also explains why the trio of mask, distance and hygiene is important in the pandemic, but that’s for another article.)
By keeping rabbits in your backyard to hunt in huge fields later let the rabbits stray not the same thing. Rabbits are suddenly spreading from one backyard to the entire continent in just 50 years. There are two main reasons for this: They do not have natural enemies and they reproduce very quickly.
Many scary creatures live on the Australian continent. Among them giant spiders, snakes, crocodiles There are such types. Come to see that most of these creatures do not know rabbits, and rabbits are not included in their diet. There is no other creature that controls the population of rabbits that do not have natural enemies.
Another factor is the enormous reproductive potential of rabbits. Rabbits from a very early age can reproduce. Since they can breed throughout the year, they can breed more than 4 times a year. In each litter, 2-5 new baby rabbits are born.
The rabbit crisis is getting so serious that colonists against rabbits and the locals start an all-out war. Although millions of rabbits perish each year, the general rabbit population is almost unaffected.
