Ants which adapt to human behaviour are considered a threat

Why do we penalise successful species and protect the failures? Almost as if we we wish to deny evolution by ensuring the survival of those which don’t deserve to survive.

If Giant Pandas were not as disinterested as they seem to be in reproducing themselves and as specialised in eating only a few species of bamboo, but instead were immensely successful in increasing their own numbers, then we would no doubt be organising Panda culls. But since they are an almost perfect example of a species bent on its own extinction we go to all possible lengths to keep them going!

Yet another story where a successful species which adapts to and make use of humans and human behaviour is then considered a “threat”. Unsuccessful species of course would become “endangered” and would then be protected!

BBCThe problem of invasive ants may be far worse than previously thought. 

A Spanish team of scientists has found that larger than expected numbers of the insects are being unwittingly shipped around the world. The researchers warn that many of these species are establishing colonies in their new habitats that could pose a threat to the environment, infrastructure and human health. The research is published in the journal Royal Society Biology Letters.

Lead author Veronica Miravete, from the University of Gerona in Spain, said: “Due to their small size, most ants are transported involuntarily in containers and other boxes, together with soil, wood, ornamental plants and fruits etc, on ships or airplanes.”

The research team looked at the numbers of exotic ants in the Netherlands, the United States and New Zealand.

They found far more of these accidental stowaways than had previously been reported.

Extrapolating from this data, they estimate that 768 exotic ant species could have been introduced around the world through trade routes.

Of these, they believe that more than 600 species could have established new colonies.

Dr Miravete said: “The number of ants arriving is very large and 85% of the introduced species are able to establish successfully. This indicates that there are many introduced species that are living around us as of yet undetected.”

While not all animals that move to a new region pose a threat, some can wreak havoc – and invasive ants are some of the worst alien offenders.
