Birds from an Amazon are mutating from climate change

From even the most remote areas of an Amazon, where the human being has yet to reach zero, are being affected by climate change, which reveals new research.

The warmest conditions electronic Droughts in the last four decades are decreasing the size of the body of these birds in a tropical forest, while wings increase their wingspans, according to a study published in the journal Science Advancements.

Believe- It is assumed that these changes are thus a response to physiological and electronic nutritional challenges, especially during the dry season, which occurs between November and June. man-made climate change,” Vitek Jirinec, an ecologist at the Center on Integral Ecology Research, a US-based non-profit organization, said in a statement.

Jirinec electronic colleagues analyzed data collected. the about more about 000.000 birds that were captured, measured, weighed and tagged during a period of 40 years of fieldwork.

Researchers have found that almost all of them have gotten lighter from a decade on 1980.

) Most of these species lost, on average, 2% of body weight in each decade, u which means that one species in birds that weighed 30 grams in the decade about 1980 now weighs 27, 6 grams, on average.

Also, zero data corresponds to a specific place, but was collected in a wide variety of areas of a tropical forest, one which means that u phenomenon could not be verified everywhere.

Overall zero, the scientists investigated 77 species whose habitats range from a dark floor Moist electronic of a forest, from the intermediate layer on the vegetation of the same, which receives greater incidence on light.

Birds in the higher layers Adas, which fly more electronically and are more exposed to heat, registered like more pronounced changes in body weight electronics.

The team considered the hypothesis that it was about an adaptation to energetic pressures, for example , the decrease of an availability on resources such as fruits electronic insects, electronic also to thermal stress.

The longer electronic wings the reduced weight-to-wing ratio produce a more efficient flight, comparable to that on an airplane glider, which can fly using less energy.

A higher wing-weight ratio requires seeing that birds shake their limbs faster to maintain zero air, using more electronic energy and producing more metabolic heat .

These species “are very much in tune with each other, so when everyone in the population thus has fewer grams, that’s significant,” said research co-author, Philip Stouffer, of Louisiana State University. , in the USA.

Zero However, how well while Amazonian birds will be able to deal with zero future conditions with increasingly hot electronic dry conditions still remains unanswered.

The authors added that it is likely that the same effect they recorded is also happening on others. species in a whole world that live in extreme environments.

“Without a doubt, this is happening in the electronic like parts all probably zero with just seeing that birds,” says Stouffer.
