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

Secondly, warming and deteriorating environmental conditions in itself lead to stress in birds. This helps to regulate the internal temperature. & 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. & Nbsp; Sparrows suffered the most & mdash; & nbsp; their population has decreased by half. But now there is more and more research on how new climatic conditions are changing the appearance and behavior of animals. This is & nbsp; the first evidence that climate change is affecting the relationship of wild birds, bird watchers emphasize. 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. Albatrosses have increased divorce rates According to statistics, every fourth biological species faces the threat of extinction in the XXI & nbsp; century. Albatrosses may think that the reason for their discomfort is in their “ spouse '' and abandon him. By that time, the female can find herself another partner. '' Истoчник aif.ru So, over the & nbsp; last 40 years & nbsp; the number of birds nesting in Europe has decreased by 17-19%. 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. By the way, the size of the human body has constantly changed in the course of evolution under the influence of climate. It was he who was the main driving factor in the evolution of the human body. Now the scientific journal of the Royal Society of London & nbsp; reported another scourge: the ongoing warming on the planet & nbsp; destroys albatross families. 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; In subsequent years, the temperature dropped, the number of divorces & mdash; too. 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. These birds are known for their fidelity. Traditionally, about 4% of couples break up in it, although in some years the divorce rate did not exceed 1%. Thanks to this, the body's thermoregulation improves, and representatives of the fauna can more easily tolerate heat. Thus, it was noticed that the beaks of helmet cockatoos and red-backed parrots grew by 4-10%. Researchers explain this phenomenon for two reasons. The colder it was in the regions where our distant ancestors lived, the more massive their bodies became, and vice versa. 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. If so, scientists can be said to have discovered 'overlooked consequences' global warming. Every sixth individual has disappeared. Scientists have known and said for a long time that global climate changes threaten the existence of many species of terrestrial fauna. “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. & nbsp; From 2004 to 2019, scientists observed a colony of black-browed albatrosses in the Falkland Islands. & Nbsp; First, albatrosses spend more time in warm water looking for food, which is why they arrive at the colony later and not in better shape. & 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; Stability in pairs gives them an advantage in flights (better coordination) and helps in raising chicks. This mainly happens when the “ spouses '' unable to leave offspring. It is through this organ that excess heat is removed 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. The main reasons & mdash; & nbsp; rising sea levels, extreme weather conditions and & nbsp; rising average overall temperatures. It is possible that something similar occurs in other monogamous species. 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. 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. & Nbsp; “ This can be seen & nbsp; and the people living & nbsp; in our time. & 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%. Such metamorphoses allow birds to spend less energy during flight, and massive wings still serve to remove heat. Among other endangered species of birds, ornithologists name yellow wagtails, starlings and larks. The fact is that a large body size helps to better retain heat.
