Please support our site by enabling javascript to view ads. Puerto Rico has announced plans for a massive cull of an invasive species of iguana and for the sale of harvested meat, according to The Associated Press. The US territory hopes to eradicate the species with a population of four million, which the AP says outnumbers humans on the island and has long been considered an invasive nuisance.

The AP said he claimed the meat was popular in areas with large Asian and Latino populations.

Growth of nonnative iguana population give Puerto Ricans a headache. Vazquez for News Iguana sunbathes near Boca de Cangrejos, Puerto Rico. SAN JUAN — Puerto Ricans used to only be able to see wild iguanas on TV and in the tiny island of Mona, a natural reserve off the west coast that has a native type of the lizard.

Not anymore. An increasing number of nonnative iguanas — which can grow to up to 6 feet long and weigh 8 lbs. — have settled on the island and raised questions on what to do about their presence. Suddenly, these green prehistoric-looking reptiles are taking shelter on people’s patios, lounging near hotel pools and causing flight delays at the San Juan international airport, where they like to sun in the runway. “The great question is how to stop these creatures that did not arrive on the island through natural means but were brought here,” said Alexis Molinares, a wildlife ecologist and environment consultant. Iguanas, says Molinares, attack Puerto Rico’s native fauna, including small crabs and bird eggs.

Alien Species Reconsidered: Finding a Value in Non-Natives by Carl Zimmer. 24 Feb 2011: Report by carl zimmer The tale of the honeybee is a sadly familiar one: a once-thriving species is on the ropes. After brutal bouts with mites and fungi, honeybees are now facing their most dangerous threat yet: a mysterious disease called colony collapse disorder. In the winter of 2010 alone, U.S. beekeepers reported losing 34 percent of their hives to CCD, which may be caused by viruses, pesticides, or some diabolical combination of factors. Researchers are working hard to figure out exactly why the honeybees are dying and how to save them because of their ecological importance. Honeybees pollinate many of the country’s fruit and vegetable crops, and they also carry out the same service for many species of wild plants. Amidst all the concern for the honeybees, it’s easy to forget an important fact about them.

The earliest records of honeybees in this hemisphere come from English settlers who arrived with hives aboard their ships in the early 1600s. Wikimedia.
