Extreme weather conditions may encourage an increase in the mad spinning of the populations, according to a new study.
Freak events, such as tropical cyclones, can have a revolutionary impact on the spin in the storm-prone regions, as these are the areas where the most aggressive of spiders will have the best chance of survival.
Researchers at McMaster University in Canada have studied the behavior of spiders to live in areas where extreme weather conditions are constantly changing their habitat.

Lead author of the study and evolutionary biologist Jonathan Pruitt said, “It is of paramount importance in order to understand the environmental impact of such a ‘black swan’ weather events in the evolution and natural selection.
“If the sea level rises, and the frequent occurrence of tropical storms will increase dramatically.
“Now, more than ever, we need to deal with the ecological and evolutionary impacts of this storm will be a non-human animal.”
The researchers studied women of the colonies of Anelosimus studiosus spider, which often finds itself directly in the path of tropical cyclones that affected the U.S. and Mexico.
Their study involved observing groups of spiders, before and after the storm, within a period of 48 hours.
Aggressiveness of the spiders measured in the speed, and the number of the attackers, who did not respond to the prey entering the web, how likely is it that the female spiders were mining men, and their own offspring will be, and how vulnerable they were to become infiltrated by predatory alien spider.
These results were compared with that of colonies of the same spiders that live in less extreme areas.
The aggressive spiders tend to be more effective in the acquisition of resources when food is in short supply, but they are also more likely to be fighting with each other if you get hungry, or overheated.
Pruitt said, “Tropical cyclones likely impacts of these two stressors due to the change in the numbers of flying prey, and with the increase of exposure to the sun and to have a more open canopy layer.
“The aggression is passed down through the generations in these colonies, and as a parent of a daughter, and has been a major factor in their survival and ability to reproduce.”
The analysis shows that after a tropical cyclone, or of the colonies, with the most aggressive spiders produced more eggs and had more offspring that survived.
This trend has been so consistent that the researchers believe that it is an evolutionary response.
Thus, there is a possibility that this could happen to more of the spin populations if the weather is all over the world will be more extreme as a result of climate change.
