in 1993 blockbuster movie Jurassic Parkscientists brought dinosaurs came back into existence By extracting their DNA From blood sucked by mosquitoes Frozen in amber.
“A hundred million years ago, there were mosquitoesJust like today,” said park owner John Hammond, played by actor Richard Attenborough. ”And, just like today, they drank the blood of animals – even dinosaur,
Now, researchers in Florida say they have done something similar.
Over the course of eight months, the University of Florida team identified DNA from 86 different species from blood sucked by the animals. Thousands of mosquitoes in Florida,
“Using mosquitoes, we caught everything from tiny frogs to the largest animals like deer and cows,” Dr. Lawrence Reeves, an entomologist at the school, explained in a. statement“And animals with very diverse life histories: arboreal, migratory, resident, amphibian, and those that are native, invasive, or endangered,”
The idea was not to bring back extinct species, but to take a snapshot of all the animals living in and around the university’s watery DeLuca Preserve.
This protected area is a protected area located 80 miles south of Orlando that is managed by the university.
To do this, scientists needed to capture mosquitoes that were well-nourished. Fortunately, these mosquitoes often remain at rest until laying eggs, and were easily caught by the researchers’ vacuum traps.
Only female mosquitoes bite because they use proteins from blood to reproduce. The blood they suck is stored in their stomachs and is later used to develop their eggs, sometimes laying 200 at a time,
Over the course of eight months, Reeves and other researchers were able to collect more than 2,000 “blood meals.” 21 species of female mosquitoes,
Analysis of the blood revealed that the mosquitoes were feeding quite indiscriminately.
Bald eagles, coyotes, rattlesnakes, otters, toads, turtles, alligators – it doesn’t matter. No species was safe.
The blood contains almost all of the region’s vertebrate biodiversity, the researchers said.
Only one of the large mammals could survive on the milk of mosquitoes.
The endangered Florida panther – one of the state’s two big cats, along with the bobcat – escaped detection by using mosquito blood.
But researchers said it might actually be a technical victory.
According to the , there are about 120 to 230 adult panthers left in the wild south of Lake Okeechobee in southeast Florida. Florida Fish and Wildlife Conservation Commission,
Panthers can be so rare that it is difficult to even find mosquitoes that eat them.
