Climate Change and Scorpion’s Fauna

Scorpion’s Endemism Makes It Vulnerable to Climate Change. Scorpions belong to family Scorpionoidea of Order Scorpiones of class Arachnida in kingdom Animalia. Estimates tell that there are about 2000 species of scorpions worldwide. Scorpions are unique in being endemic to a particular area. Because of endemism, scorpions face hard future times. Climate change is presenting a challenge to scorpions’ fauna.

General characteristics

Scorpions are predatory in nature. The most frightening character of scorpions is their sting. Although most of them are not as fatal to humans as they are thought of. But the very name of sting and frightening body posture makes it dangerous. Scorpions are related to mites and ticks. Scorpions generally feed on insects but diet may be variable.

Scorpion has four pairs of legs. At end of the long tail is telson with a vesicle.

Distribution

Geographically, scorpions are present all over the earth except for Antarctica and some other areas.

Use in pharmacology

Because of frightening sting and body posture, people generally consider scorpions harmful and kill it. However, medical research finds that people in Asia and Africa are using venoms for health problems for hundreds of years. These venoms from scorpions are in practice from antibiotics development up to anticancer therapeutics. Neurotoxins of scorpions induce paralysis and also affect cardiac functionality.

Components of the scorpion’s venom

A number of peptides, enzymes, inorganic salts, heterocyclic components, amines, nucleotides, lipids, free amino acids, nucleoproteins, and other unknown substances are part of venom of scorpions. Non-disulfide-bridged peptides are also a major component of the venom of the scorpion. Neurotoxin is the second name of scorpion’s venom, affecting the nervous system.

Climate change and scorpions

Scorpions are known for their worldwide distribution. They have the phenomenon of being highly endemic. A recent research study shows that the endemism lifestyle marks scorpions at high risk. If there is no migration and negative climate change hit the scorpions, they will verge it out with no exception. The model used in the study predicts that if they do not show dispersal ability, the following decades will greatly affect this species diversity. Therefore, we assume that negative climate change and scorpion’s fauna cannot go together further.

What we can do?

In the present and future scenarios, we can make it possible to conserve this species. This can be done by conserving the active hotspot and habitat of scorpions worldwide. In last we promise to mentally prepare people not to kill scorpion species as they play their role in maintaining this biosphere.

Let climate change and scorpion’s fauna go together.
