Global warming can cause a lotunpleasant consequences. One of them may be the increased aggressiveness of arthropods such as spiders. Even if you do not have arachnophobia, after reading this article you may have a strong desire to make your personal contribution to the fight against global warming and environmental pollution.
How does climate change affect spiders?
That sea level rise and general changeclimate already affects our daily life with you, is an indisputable fact. In order to assess the level of influence of climate change not only on our lives, but also on the lives of animals, a group of researchers from Canada and the United States, led by Alexander Little of the University of California at Santa Barbara, studied the behavior of the spider Anelosimus studiosus on the Atlantic coast of North America. A. studiosus lives in colonies over rivers and streams; some of the individuals of this species are very aggressive towards humans. According to an article published in Nature Ecology and Evolution, past studies of the life of these arthropods have already shown that colonies as a whole can be aggressive or more or less peaceful, based on the resources to which the spider colony has access.

Because cyclones and storms can change the environmenthabitats of individual animals and insects, perhaps they also change the behavior of entire colonies. To study this, researchers needed to measure the aggressiveness of the colonies and how well they flourished before and after the onset of the cyclone. In order to determine the aggressiveness of the spiders, the researchers conducted a small experiment, to which the spiders had to react in some way before and after the storm.
As observations have shown, after cyclone moreaggressive colonies produced far more eggs and had more cubs than their non-aggressive counterparts. One can easily guess that the spiders really became the most annoyed in those places, which fell to share the most severe consequences of the storm.
Why do spiders become more aggressive?
As to why the spiders got angry,The researchers had several ideas. Most likely, immediately after the cyclone, the colony ceases to miss the available prey, forcing spiders of the species Anelosimus studiosus not only to be in constant search for food, but also to look for a place for new migration. In other words, after the onset of the climatic apocalypse, spiders can become much more hungry and evil. Due to its increased aggressiveness, it is arthropods that can become overwhelming in their numbers species on planet Earth, compared with all others.

How can global warming affect animals?
As spiders begin to populate new onesterritories in search of food, while becoming almost the dominant species on the planet, many animals known today will have a hard time. So, penguins and polar bears, which are extremely susceptible to climate change, may be at risk. Due to the fact that both of them spend most of their lives on the ice, which is currently steadily losing their size, by 2050 we risk losing up to 70% of these animals.
Besides northern animals, the planet is at risklose some southern species. It is known that the well-known pink flamingos mate only in the rainy season. Due to the fact that global warming entails droughts, the long absence of rain will greatly affect the number of individuals in the population. In addition, the gradual accumulation of toxins in the blue-green algae, which are the main source of nutrition for these birds, also will not lead to anything good.
Australian koalas are also at risklose your main food. The fact is that the main source of energy in these animals is eucalyptus. Due to temperature changes, eucalyptus trees begin to grow very slowly, while not spreading beyond their range. Reducing the amount of food obtained in this case threatens the koalas with a gradual extinction.

The existence of such a miracle of nature as the Greatthe barrier reef is also endangered. The fact is that due to the increase in ocean temperature, coral reefs gradually discolor and die, forcing their inhabitants, such as amphiprion fish from the well-known cartoon "Finding Nemo", to look for a new habitat.
