Global warming can cause many unpleasant consequences. One of these could be the increased aggressiveness of these arthropods, like spiders. Even if you don’t have arachnophobia after reading this article, you may have a strong desire to make a personal contribution to the fight against global warming and environmental pollution.
As climate change affects spiders?
The fact that the sea-level rise and General climate change already affects our daily life, is an indisputable fact. In order to assess the level of climate change impact not only on our lives but on the lives of animals, a group of researchers from Canada and the United States headed by Alexander little, University of California, Santa Barbara studied the behavior of the spider Anelosimus studiosus, on the Atlantic coast of North America. A. studiosus lives in colonies on the rivers and streams; some of this species are very aggressive towards humans. According to the article, published in Nature Ecology and Evolution, past studies of the lives of these arthropods have already shown that the colonies in General can be aggressive or more or less peaceful, based on the resources that the spider colony has access to.

Since cyclones and storms can change the habitat of the individual animals and insects, they may also change the behavior of whole colonies. To study this, researchers had to measure the aggressiveness of the colonies and how well they thrived before and after the onset of the cyclone. In order to determine the aggressiveness of spiders, the researchers conducted a small experiment in which spiders had to react in any way before and after the storm.
Observations showed, after the cyclone more aggressive colonies producing a lot more eggs and had more cubs than their non-aggressive counterparts. You can easily guess that the spiders really were the most irritated in those areas, which fell to move the strongest effects of the storm.
Why spiders become more aggressive?
As for why the spiders are wicked, the researchers had a few ideas. Most likely, immediately after the cyclone colony no longer enough available production, causing the spider species Anelosimus studiosus is not just to be in a constant search for food, but also to look for new migrations. In other words, after the onset of the climatic Apocalypse spiders may be more hungry and angry. Due to its increased aggressiveness, that arthropods can become overwhelming in numbers species on the planet Earth, compared to all the others.

How global warming can affect animals?
While the spiders will start to settle in new territory in search of food, and thus become almost the dominant species on the planet, many of the currently known animals have had very hard times. Thus, danger can be penguins and polar bears, which are extremely susceptible to climate change. Due to the fact that those other a large part of their time on the ice, which is currently steadily losing their dimensions, by 2050, we risk losing up to 70% of these animals.
In addition to the Northern animals, the planet risks losing some of the southern species. It is known that all the famous pink flamingos will mate only during the rainy season. Due to the fact that global warming leads to drought, the long absence of rain will greatly affect the number of individuals in the population. In addition, the gradual accumulation of toxins in blue-green algae, which are a major food source of these birds, and will not lead to anything good.
Koalas are native to Australia, also risk losing their staple food. The fact that the main source of energy in these animals is eucalyptus. Due to temperature change gum trees start to grow very slowly, while not extending further its range. Reducing the amount of food produced in this case threatens koalas gradual extinction.
You may be wondering: Who can survive global warming?
The existence of such a natural wonder like the Great barrier reef is under threat. The fact is that because of higher ocean temperatures coral reefs gradually fade and die, forcing their inhabitants such as fish amphiprion of all the famous cartoon “finding Nemo”, to seek a new habitat.
