Climate-lovebird. How warming is changing the appearance and behavior of animals


& Nbsp; Sparrows suffered the most & mdash; & nbsp; their population has decreased by half. & Nbsp;
“ This can be seen & nbsp; and the people living & nbsp; in our time. It was he who was the main driving factor in the evolution of the human body. In bats of the species & nbsp; Hipposideros armiger & nbsp; wing size increased by 1.64%, shrews have more & nbsp; tails and paws, rabbits & nbsp; ears, and boars & mdash; & nbsp; ears and tails. & Nbsp; Stability in pairs gives them an advantage in flights (better coordination) and helps in raising chicks. This helps to regulate the internal temperature. By the way, the size of the human body has constantly changed in the course of evolution under the influence of climate. If so, scientists can be said to have discovered 'overlooked consequences' global warming. & Nbsp; The main causes of extinction & mdash; & nbsp; destruction of natural habitats, & nbsp; urbanization, & nbsp; widespread use of pesticides and other chemical pollution, as well as climate change. & nbsp; From 2004 to 2019, scientists observed a colony of black-browed albatrosses in the Falkland Islands. Albatrosses may think that the reason for their discomfort is in their “ spouse '' and abandon him. & Nbsp; In subsequent years, the temperature dropped, the number of divorces & mdash; too. Researchers explain this phenomenon for two reasons. In general, there is a rule, discovered at the end of the 19th century, that in colder climates in warm-blooded animals the protruding parts of the body are smaller than in their relatives in hot climatic zones. Thanks to this, the body's thermoregulation improves, and representatives of the fauna can more easily tolerate heat. & Nbsp; In & nbsp; 2017, when the temperature was the most high for & nbsp; all the time of observation, the share of partings peaked & mdash; 7.7%. They live up to 50 (and even more) years, spending a significant part of their life in the ocean in search of food, and return to land only to reproduce. ''

It is through this organ that excess heat is removed in birds. & mdash; & nbsp; Now we know that over the past million years & nbsp; the appearance of representatives of the genus & nbsp; Homo & nbsp; was significantly influenced by the climate. Secondly, warming and deteriorating environmental conditions in itself lead to stress in birds. Those & nbsp; who live in warmer climates are generally & nbsp; smaller than those in the temperate and northern latitudes, & nbsp; says & nbsp; University of Cambridge professor of zoology Andrea Manica who led the study. This is & nbsp; the first evidence that climate change is affecting the relationship of wild birds, bird watchers emphasize. But now there is more and more research on how new climatic conditions are changing the appearance and behavior of animals. Ears, feet and tails: size matters
Australian researchers concluded that due to global warming over the past 150 years, animals and birds have increased in size in beaks, ears, paws and other body parts. Now the scientific journal of the Royal Society of London & nbsp; reported another scourge: the ongoing warming on the planet & nbsp; destroys albatross families. Albatrosses have increased divorce rates
According to statistics, every fourth biological species faces the threat of extinction in the XXI & nbsp; century. The main reasons & mdash; & nbsp; rising sea levels, extreme weather conditions and & nbsp; rising average overall temperatures. Their couples rarely break up, they remain with the same partner for decades and together make long flights to find a place for nesting and incubation of offspring. The colder it was in the regions where our distant ancestors lived, the more massive their bodies became, and vice versa. Among other endangered species of birds, ornithologists name yellow wagtails, starlings and larks. “This stability is especially important in a dynamic marine environment,” & mdash; & nbsp; says Francesco Ventura, an environmental biologist at the University of Lisbon, one of the authors of the study. Every sixth individual has disappeared. The fact is that a large body size helps to better retain heat. Thus, it was noticed that the beaks of helmet cockatoos and red-backed parrots grew by 4-10%. So, over the & nbsp; last 40 years & nbsp; the number of birds nesting in Europe has decreased by 17-19%. Such metamorphoses allow birds to spend less energy during flight, and massive wings still serve to remove heat. These birds are known for their fidelity. Bird watchers monitored the behavior of 424 females and noticed that & nbsp; in those years, & nbsp; when the water was warmer, & nbsp; the percentage of their divorces with partners almost doubled. Scientists have known and said for a long time that global climate changes threaten the existence of many species of terrestrial fauna. This mainly happens when the “ spouses '' unable to leave offspring. It is possible that something similar occurs in other monogamous species. Traditionally, about 4% of couples break up in it, although in some years the divorce rate did not exceed 1%. By that time, the female can find herself another partner. Another study by scientists from Louisiana State University showed that since the 1980s, the wings of Amazonian birds have become longer, while their bodies have shrunk at the same time.
