Recently, a study over the spiders has found that the population of spiders in the Guam’s jungles is 40 times more than the population in nearby Pacific islands. The findings have been published in the journal PLoS One.

During the study, it further came to light that the local birds have been completely wiped out from the Guam’s jungles. Besides, the population of bird-eating snakes has multiplied by manifolds in the jungles. This particular breed of snakes was introduced in the jungles of Guam in 1940s.

It is believed that small population of birds has encouraged the spiders to dwell in the area. As birds eat spiders and other insects, the large population of spiders is quite justifiable. The study was conducted by the researchers of Rice University.

The author of the study, Haldre Rogers, was reported saying, “With insectivorous birds in decline in many places in the world, I suspect there has been a concurrent increase in spiders”. The authorities of the US, spends $1 million every year to prevent the spread of bird-eating snakes to other regions. The reduced population of birds has caused serious concerns to the authorities. Steps will be taken to restore the population of the birds in the Guam’s jungles.
