Howler monkeys from Veracruz are found dead due to the heat 

Howler monkeys from Veracruz are found dead due to the heat

More and more species from Mexico and around the world are affected by climate change, these changes in the planet that leads to death.

Just a couple of weeks ago this medium reported that hundreds of birds in the state of San Luis Potosí, were falling dead due to rising temperatures and lack of water.

Well now the affected fauna is the howler monkey from the jungle of Veracruz. At least 10 of these monkeys have been found dead on the branches of trees or among fallen leaves, and that is that temperatures exceeded 40 degrees.

The drought of just over three months in the jungle of southern Veracruz has caused great damage, not only in crops and livestock, but in the life of the habitat.

325 monkeys found dead during the past month in Rio de Janeiro, Brazil

With the outbreak of yellow fever this year, a slaughter of monkeys is underway. In the State of Rio de Janeiro, were found 325 dead monkeys since the 1st of January until this Wednesday (21). Of this total, 53.5 percent were victims of human aggression. In the city of Rio were found 170 dead primates in the period.
According to data released by the Health Department of Rio de Janeiro, throughout last year were found dead animals-602-41% being victims of aggression.

Yellow fever killing thousands of monkeys ‘unprecedented’ in Minas Gerais, Brazil

In a vulnerable forest in southeastern Brazil, where the air was once thick with the guttural chatter of brown howler monkeys, there now exists silence. Yellow fever, a virus carried by mosquitoes and endemic to Africa and South America, has robbed the private, federally-protected reserve of its brown howlers in an unprecedented wave of death that has swept through the region since late 2016, killing thousands of monkeys.
Yellow fever, a virus carried by mosquitoes and endemic to Africa and South America, has robbed the private, federally-protected reserve of its brown howlers in an unprecedented wave of death that has swept through the region since late 2016, killing thousands of monkeys.
Karen Strier, a University of Wisconsin-Madison professor of anthropology, has studied the monkeys of this forest since 1983. She visited the reserve — her long-term study site near the city of Caratinga — in the state of Minas Gerais, in January of 2017. “It was just silence, a sense of emptiness,” she says. “It was like the energy was sucked out of the universe.”
Using what in some cases are decades of historical data, Strier and a team of Brazilian scientists focused on studying primates in Brazil’s patchwork Atlantic Forest are poised to help understand and manage what happens next. They have never seen monkeys perish in such numbers, so quickly, from disease.
With her Brazilian counterpart Sérgio Lucena Mendes, a professor of animal biology at the Universidade Federal de Espirito Santo, and their former postdoctoral researcher, Carla Possamai, Strier is ready to census the monkeys that remain at the reserve, comparing the new data to prior censuses performed in the forest. They also plan to study how the surviving brown howler monkeys regroup and restructure their societies, since their existing social groups have been destroyed.
Strier’s study forest, just 4 square miles in size, is a land-locked island of green surrounded by agricultural and pasture lands. How yellow fever showed up here is a mystery, and the monkeys in the forest have nowhere else to go. Less than 10 percent of Brazil’s Atlantic Forest remains intact and much of it exists only as small patches in a fragmented landscape.
“I am very surprised at the speed with which the outbreak is advancing through the landscape and by how the virus can jump from one patch of forest to another, even if they are hundreds of meters apart,” says Mendes. “It is also surprising that it is spreading across such a large geographic region.”
The way yellow fever has spread also concerns Brazilian health officials. As of mid-March 2017, they have confirmed more than 400 human cases of the disease, mostly in Minas Gerais, causing nearly 150 human deaths. The Brazilian Ministry of Health is investigating another 900 possible cases and concern is mounting that it will spread to cities, threatening many more people.
Brazilian authorities also want to protect the monkeys from people who fear the animals may be spreading the disease. “We need to show that they help inform when the virus arrives in a region, because being more sensitive than humans, they die first,” Mendes explains.
A dead monkey is like a canary in a coal mine, alerting public health officials that a pathogen may be present, mobilizing preventative and precautionary efforts. So, what does it mean when so many have perished?
“No one really knows the consequences for the other primates or the forest when nearly the entire population of an abundant species dies from disease in just a few months,” says Strier. “We are in a position to learn things we never knew before, with all the background information that we have collected.”
Nearly two decades ago, Strier helped expand and secure protection for the primates at her study forest, which include four monkey species: the brown howler, the black capuchin, the buffy-headed marmoset and, Strier’s animal of interest, the critically-endangered northern muriqui.
It is too soon to say whether the howler monkey population can recover but Strier remains optimistic, in large part because of a career spent studying and helping conserve the brown howler’s main competitor, the muriquis. “The muriquis have shown us that it’s possible for small populations of primates to recover if they are well-protected,” says Strier.
When she first arrived at her study forest, known as RPPN Feliciano Miguel Abdala, there were just 50 muriquis. By September 2016, there were nearly 340, representing one-third of the species’ total known population. The animals reside in just 10 forests in southeastern Brazil and nowhere else in the world. Strier’s efforts and those of her colleagues have helped restore their numbers.
She is relieved that, so far, the muriquis appear to be less susceptible to yellow fever. “It was really tense — scary — to go into the forest, knowing the howlers were gone but not knowing how bad things might also be for the muriquis,” Strier recalls.
Her long-term studies have revealed that muriquis have a lifespan of more than 40 years and she has known some of the individual muriquis in the forest their entire lives. Strier can recognize individuals based on natural differences in their fur and facial markings.
Now, in the face of ecological tragedy, she and her colleagues have an opportunity to study how the muriquis adapt in a forest nearly devoid of their competitors.
“It’s like a controlled natural experiment, but one you would never plan to do,” Strier says. “My happy hypothesis is that the muriquis are out foraging, feasting on all the best fruits and leaves that the howlers used to eat. Will they eat more of their favorite foods, or travel less? Will their social order change? Will they form smaller groups?”
She has documented that kind of behavioral flexibility before. In the late 1980s and early 90s, the muriquis began splitting into smaller groups. In the early 2000s, as their population grew, they began spending more time on the ground, rather than in the trees, often consuming fallen fruits and even half-eaten “leftovers” under the trees.
“I feel like I am 20 years old again” she says. “I have so many questions that are important to answer, for the primates, their Atlantic forest habitat, and for the people that share their world.”

400 dead monkeys found in the forests of Espirito Santo, Brazil

In the Atlantic Forest of Espírito Santo, where different species of monkeys lived in a racket, silence remained. The disappearance of the monkeys attracted attention and residents and researchers from the Federal University of Espírito Santo. They found many dead animals in the forest. In one week they counted 400 dead monkeys of endangered species. The suspicion is that they may have been bitten by mosquitoes transmitting yellow fever. The cases of yellow fever in the region began in the East of Minas and arrived in Espírito Santo.

Dozens of monkeys are dying off, ‘a mystery’ in the forests of Nicaragua

Scientists are investigating the mysterious die-off of dozens of monkeys in Central America, including the possibility that they have contracted Zika or another virus that could be passed to humans.
In recent months, around 40 howler monkeys have been found dead or dying in the tropical rainforests of Nicaragua. The animals have all had relatively full stomachs and no obvious signs of trauma. Experts fear there may be many more cases that have not been reported. 
“Wild animals die off all the time, but it is really unusual to see this many deaths in such a short time with no apparent reason,” said Kim Williams-Guillen, a conservation Ph.D. who has been researching in Nicaragua’s jungles since 1999. “I have never seen anything like it.”
“These deaths are worth investigating, not just from a conservation standpoint, but from a public health standpoint. It is very important we get to the bottom of this.”
Primates are highly susceptible to mosquito-borne diseases, and outbreaks among them could be a precursor to the spread of disease among humans, although scientists are careful to warn that this leap remains rare.
Complicating the mystery is the fact that howler monkeys are immune to dengue but are highly vulnerable to yellow fever. Yet Nicaragua has been declared free of that disease for years.
What is less clear is how the primates will respond to Zika and chikungunya, both of which are related to yellow fever and have just arrived in the Western Hemisphere in the last couple of years. 
Nicaragua has reported 29 cases of Zika so far. Meanwhile, chikungunya has infected more than 100,000 people across Central America since first arriving there in 2014. 
Among the numerous unknowns is whether howler monkeys would even exhibit symptoms if they became infected with either virus.
“It is just not something that has been researched yet, how or whether they would affect primates,” adds Williams-Guillen, who is conservation director at Paso Pacifico, an environmental nonprofit working in Central America’s Pacific jungles. 
The group is now coordinating with scientists from the University of California, Davis, to come up with a definitive diagnosis for whatever it is that is killing off the monkeys.
In addition to the possibility of a virus, the researchers will also probe other factors that might be at work, including drought and other environmental variables.
The first challenge is to take hair, skin and other samples from a recently deceased animal and then transport it to Davis.
Liliana Cortez Ortiz, a University of Michigan researcher and member of the International Primate Specialist Group of the International Union for the Conservation of Nature, said this kind of unexplained die-off of apparently healthy animals is unusual, but not unprecedented. 
“Any instances in which primates are dying from unknown causes is potentially a concern for humans as well,” she added. “We simply don’t know why this is happening and we need to find out.”
Despite their cute appearance and size, typically weighing around 17 to 20 pounds, howler monkeys are actually the loudest land animals on the planet. 
That’s because they have large, hard, hollow throats, which they use to project roars that can travel for miles across the jungle. To the untrained ear, they sound more like a big cat than a fluffy monkey.
But now that they are apparently suffering from a mystery disease, they also face a new threat, warns Cortez Ortiz: humans.
“Now that we know they are dying, it is possible that local people may become scared and take matters into their own hands, killing the monkeys deliberately out of fear,” she said.
“It is very important that they message gets out in Nicaragua that that is not the way to handle this, and these monkeys are not a danger to humans.”

70 Monkeys found dead throughout Kheragarh in India

More than 70 monkeys have been found dead in different parts of Kheraghar, about 50 km from Agra, in the past three days, with autopsy reports saying the animals were poisoned.
Authorities suspect that someone may have poisoned the animals to control the simian menace.
According to the police, the 31 monkeys that were found dead on Saturday had vomited a green-coloured substance. .
Fourteen monkey bodies were recovered from Sarendhi Bridge. On Thursday, 13 monkeys were found dead near Jhinjhin Pulia.
Local people expressed shock at the cruelty. “It was terrible to see the animals lying with their mouths open, the green substance flowing out. It was hard to tell whether the monkeys died here or elsewhere, and their carcasses brought here,” said Sonu, a cable operator in Kheraghar who informed police about the large number of dead monkeys.
A forest official said, “For so many monkeys to go down in such a short span of time, it must have been poison. They showed symptoms of that – excess salivation, seizures, respiratory distress.”
Sudhir Kumar, inspector at Saiyya police station, said, “For the first time, we have had something like this in this area. It is possible that the monkeys were killed somewhere else and the carcasses disposed of here. It is possible that given the monkey menace in Agra, someone had poisoned them. An FIR has been registered under sections of IPC dealing with cruelty to animals.”
In the last four years, the monkey population in Agra has gone up three times. Since 2012, the project cost for making the city of Taj free of monkeys has nearly doubled. Sources in the district forest office said nearly 25,000 monkeys now roam the city; in 2011, the simian population here was estimated at 9,000. In 2011, the cost of making Agra monkey-free was estimated at Rs 9 crore. Now, the sum has risen to Rs 15 crore.
