A “toxic soup”: this was the worst extinction on Earth | Digital Trends Spanish

The late Permian mass extinction event of about 252 million years ago is considered the worst such event in our planet's history. This period has been associated with large volcanic greenhouse gas emissions, a significant increase in temperature, and the loss of almost all species of animals in the oceans and on land. Now, a group of researchers says that not even rivers and lakes were safe havens for different species, since a new cause of extinction during extreme warming events has been identified: toxic microbial blooms. In a healthy ecosystem, microscopic algae provide oxygen to aquatic animals, but when this number gets out of control, microbes deplete free oxygen and start releasing toxins into the water.

This reveals the oldest cavities found in a mammal | Digital Trends Spanish

Analysis of dental fossils of the primate species Microsyops latidens, dating to about 54 million years ago, show the first evidence of dental caries in mammals. The study was published in the journal Scientific Reports and shows cavities, probably caused by a diet generous in fruits or other foods high in sugar. The remains of this species have been studied for several years. Before, small holes had been detected in the teeth, which were thought to be due to physical damage that occurred before the disappearance of the mammal. "These fossils have been around for 54 million years and a lot can happen in that time," explains Keegan Selig, lead author of the study. Keegan Selig"I think most people assumed that these holes were some kind of damage that occurred over time, but they always ...

Strange find of a pig-faced shark | Digital Trends Spanish

Nature still has many surprises to offer us, especially at the bottom of the oceans, where there is very little we have explored. A few days ago, a group of Italian sailors took out of the waters of the island of Elba, a rare specimen of Oxynotus centrina, a kind of shark famous for its unique appearance, as it would have a "pig's face." In fact, this animal is popularly known as “pig fish”. “In the water, it looks like any other shark: a fast, gray hunter with steep dorsal fins that stick out from its back. But if you look closely at his face, you suddenly come across a real-life pig emoji, ”notes a post from Live Science. According to the people who found this specimen, it is also called a pig because of the strange sound it makes when it is taken out of the water. "It is commonly ca...

Cows are taught to go to the toilet to curb climate change | Digital Trends Spanish

The increase in the temperature of the planet is a serious problem that affects all species of animals that exist on Earth. The problem is that this phenomenon worsens over the years, therefore, scientists and international authorities have called on humanity to react in time. This urgent need to act has motivated the most unusual proposals. It has been proven that the waste that cows eliminate on farms constitutes one of the major sources of polluting gases, increasing the levels of CO2 in the atmosphere. This helps to raise the global temperature of the planet, for this reason, a group of scientists has proposed as a solution that these animals use toilets, like humans, to eliminate their organic waste. In this way, the managers of the farms and stables, will be able to carry out a tr...

Climate change now threatens the Komodo dragon | Digital Trends Spanish

According to a new report from the Union for Conservation of Nature (IUCN), the Komodo dragon, known as Varanus komodoensis, It is in danger of extinction. This animal is considered the largest lizard in the world, as well as being one of the largest predators in the animal kingdom, since it is capable of detecting its prey from 12 kilometers away. According to the new report, climate change and rising temperatures will cause the Komodo dragon's habitat to shrink by at least 30 percent in the next 45 years. This supposes a drastic reduction of their habitat which would seriously affect the survival of this species. For these reptiles, the main problem is due to the fact that the increase in temperature and the increase in the level of the oceans will dramatically reduce the amount of la...

A crocodile attacks and destroys a drone that was recording it | Digital Trends Spanish

Humans find another way to annoy animals and not leave them alone in their natural habitat. A group of tourists went to the wetlands in southern Florida, in the Everglades National Park to film the crocodiles that live in that place up close with a drone. The problem is that, without thinking about the tranquility of this species, they got very close to a specimen that was resting peacefully in the water. At one point, people got very close to the DJI Spark drone and the crocodile did not hesitate to perform a spectacular jump and capture the device in the air. Reference image. Getty Images.After this, he proceeded to bite him violently, destroying him. In the video it is not possible to see if the reptile ate the aircraft, what is appreciated is that the drone was totally destroyed. ...

Mammals are bigger as a result of cities | Digital Trends Spanish

New research shows that urbanization is causing many species of mammals to increase in size, likely due to the availability of food in crowded places. Researchers at the Florida Museum of Natural History discovered an unexpected pattern after analyzing nearly 140,000 measurements of body length and mass from more than 100 species of mammals that inhabit North America over 80 years. According to the results of the study, the mammals that live in the city are longer and larger than those that live in the countryside. "In theory, animals in cities should get smaller and smaller due to the effects of the heat island, but we have not found evidence that this occurs in mammals," explains lead study author Maggie Hantak, a researcher. from the Florida Museum. "This work is a good argument for ...

This application can “see” the pain suffered by cats | Digital Trends Spanish

This application will be very useful for pet owners, especially when they do not know what pain affects their animals. A company specialized in animal health technology developed an application that is capable of determining the pain that a cat feels. For this, it uses the camera of a mobile device with which it analyzes the facial expressions of the feline. To detect possible discomfort in cats, the app assesses the position of the ears and the head, as well as the contraction of the eyes, the tension of the muzzle and the changes in the whiskers. "It helps cat owners to know if their pet is in pain or not," explains Miche Priest, from the company in charge of this tool, in a Reuters article. Todd Korol."We were able to train a machine with machine learning algorithms and a series of ...

Austrian cockatoos learn to open garbage containers | Digital Trends Spanish

Cockatoos have gone from being birds that inhabit forests and mangroves to becoming all survivors of the big city. So much so, that these animals have learned a very human and complex gesture to perform for their anatomy, for the sake of their own survival. According to a study published in the journal Science Led by Barbara Klump and Lucy Aplin (of the Max Planck Institute for Animal Behavior), along with John Martin (Taronga Conservation Society) and Richard Major (Australian Museum), cockatoos have acquired the ability to lift the lids of containers of garbage feed. But the most striking thing about the study is that these animals learn from each other to perform this gesture, a very unusual behavior in birds. The birds were recorded for several years and by checking the recordings,...

This bat wears a mask for a particular reason | Digital Trends Spanish

This 2020, bats have become more popular and it is not only because of the next premiere of The batman (definitively postponed to 2022). This enigmatic animal has been associated with the genesis of the coronavirus, a pandemic that has the entire planet in check. We are constantly learning more about this creature that amazes us, and recently we have learned of a new species that can use a very appropriate "accessory" for these times. It's about the species Centurio senex, who uses a kind of mask on his face and whose main characteristics and behavior have been detailed in an observational study published in PLOS One. Preliminarily, the mask is thought to be part of a courtship ritual for males. This "accessory" would be incorporated into your face and would be made with excess sk...
