Climate change may increase the amount of poisonous spiders


26/04/2011

One of the most horrific species of spiders in North America has been the subject of a new study, aiming to predict possible areas of its distribution and how it spread may be due to climate change.

Spider, commonly known as the brown recluse (Loxosceles reclusa), injects powerful venom that can kill the tissue sections on the body at the site of the bite. This can lead to painful deep wound which rarely zarubtsovyvaetsya. But the wounds are not always easy to diagnose. Health care providers can confuse the bite with other serious diseases, including Lyme disease and various types of cancer. The distribution terms of spiders are not yet fully known to the scientists and medical experts continue to diagnose patients with bites of brown recluses in areas where, as you know, they do not have to dwell.

Better characterizing the spread of evil insects and to explore potential new areas of distribution related to future climate change, the medical community and people will be more aware of this kind of dangerous insects, as the author said Erin analysis Sop (Erin Saupe). Sop is a graduate student at the Institute of Geology and Biodiversity.

In order to solve the problem of a brown recluse spider, Sop and other researchers have used the method to help predict the distribution, which has been called ecological niche modeling. They used the scenario of future climate change to the known distribution of spiders in the Midwest and southern regions of the United States. The researchers concluded that the range of species may expand closer to the northern part, potentially capturing the regions that had never seen these species. The affected area may become part of Nebraska, Minnesota, Wisconsin, Michigan, South Dakota, Ohio, and Pennsylvania.

"These results illustrate the potential negative consequences of climate change that will affect the people and at the same time will help healthcare professionals to accurately identify bites and their treatment, potentially reducing the likelihood of misdiagnosis bite" - said Sop.

The research paper was published in the March edition of the journal "PLoS ONE".
