After the rains, populations of frogs explode in Vermont

A new case of invasive animals, although perhaps only temporary, is involving a region of the United States. This time the area affected is that of Vermont: in this state, there has been a real explosion of the population of frogs that have been seen numerous times, even in fields and meadows or on the roads where they are often crushed by the wheels of the vehicles in transit.

According to James Andrews, a researcher at the University of Vermont, the population of the northern leopard frog appears to have literally exploded so much that the witnesses themselves and the locals claim to have never seen so many frogs in their lives. According to the researchers, the explanation lies in the weather conditions that occurred this year. In fact, since the beginning of the year, there have been periods of high humidity and heavy rain, which has led the fields to hold water for months.

And this, in turn, led to the proliferation of frogs that found the right environment to reproduce. In particular, the northern leopard frog takes advantage of the grassy alluvial plains to lay eggs. This animal lays down so many because, at least under normal conditions, many embryos die even before they are born. This did not happen in part this year. There was also heat to accelerate the development of tadpoles.

Hundreds of thousands of frogs were born, groups that are now partly moving from kilometer to kilometer in every direction, reaching even the inhabited centers. It is on the roads, however, that one can speak of “massacre:” according to the researcher, at least over 400,000 bodies of dead frogs are crushed by vehicles on the roads of Vermont. It is a carnage that also has rather unpleasant effects not only from a visual point of view but also from an olfactory one.
