More than 100 dolphins have died in the Brazilian Amazon rainforest in the past week as the region grapples with a severe drought, and many more could die soon if water temperatures remain high, experts say.

The Mamiraua Institute, a research group of Brazil’s Ministry of Science, Technology and Innovation, said two more dead dolphins were found Monday in the region around Tefe Lake, which is key for mammals and fish in the area. Video provided by the institute showed vultures picking at the dolphin carcasses beached on the lakeside. Thousands of fish have also died, local media reported.

Experts believe high water temperatures are the most likely cause of the deaths in the lakes in the region. Temperatures since last week have exceeded 39 degrees Celsius (102 degrees Fahrenheit) in the Tefe Lake region.

The Brazilian government’s Chico Mendes Institute for Biodiversity Conservation, which manages conservation areas, said last week it had sent teams of veterinarians and aquatic mammal experts to investigate the deaths.

There had been some 1,400 river dolphins in Tefe Lake, said Miriam Marmontel, a researcher from the Mamiraua Institute.

“In one week we have already lost around 120 animals between the two of them, which could represent 5% to 10% of the population,” said Marmontel.

Workers have recovered carcasses of dolphins since last week in a region where dry rivers have impacted impoverished riverside communities and stuck their boats in the sand. Amazonas Gov. Wilson Lima on Friday declared a state of emergency due to the drought.

Nicson Marreira, mayor of Tefe, a city of 60,000 residents. said his government was unable to deliver food directly to some isolated communities because the rivers are dry.

Ayan Fleischmann, the Geospatial coordinator at the Mamirauá Institute, said the drought has had a major impact on the riverside communities in the Amazon region.

“Many communities are becoming isolated, without access to good quality water, without access to the river, which is their main means of transportation,” he said.

Fleischmann said water temperatures rose from 32 C (89 F) on Friday to almost 38 C (100 F) on Sunday.

He said they are still determining the cause of the dolphin deaths but that the high temperature remains the main candidate.

Drinking a few cups of caffeinated coffee or tea every day may help in a small way to preserve brain power and prevent dementia, researchers reported on Monday.

People with the highest daily intake of caffeinated coffee had an 18% lower risk of developing dementia compared to those with the lowest such intake, according to a study based on responses to questionnaires by 132,000 U.S. adults spanning four decades.

The study, published in JAMA, also found that the people with the highest intake had a lower rate - by nearly 2 percentage points - of ‌self-perceived memory ‌or thinking problems compared to those with ‌the ⁠lowest intake.

Results were ‌similar with caffeinated tea, but not with decaffeinated beverages, the researchers said.

While the findings are encouraging, the study does not prove caffeine helps protect the brain, they said.

The magnitude of caffeine's effect, if any, was small, and there are other better-documented ways to protect cognitive function as people age, study leader Dr. Daniel Wang ⁠of Harvard Medical School said in a statement.

Lifestyle factors linked with lower risks of ‌dementia include physical exercise, a healthy diet ‍and adequate sleep, according to previous ‍research.

"Our study suggests that caffeinated coffee or tea consumption can ‍be one piece of that puzzle," Wang said.

The findings were most pronounced in participants who consumed two to three cups of caffeinated coffee or one to two cups of caffeinated tea daily, the researchers reported.

Those who drank caffeinated coffee also showed better performance on some objective tests of cognitive function, according to the ⁠study funded by the National Institutes of Health.

Further research is needed to validate the factors and mechanisms responsible for the findings, the researchers said.

They noted that bioactive ingredients in coffee and tea such as caffeine and polyphenols have emerged as possible factors that reduce nerve cell inflammation and damage while protecting against cognitive decline.

"We also compared people with different genetic predispositions to developing dementia and saw the same results - meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing ‌dementia," study coauthor Dr. Yu Zhang of the Harvard T.H. Chan School of Public Health said in a statement.

The National Center for Wildlife (NCW) announced that the total number of wildlife animals released under its breeding and reintroduction programs for locally threatened species has exceeded 10,000 animals, an achievement reflecting the scale of the center’s sustained efforts to develop wildlife, restore ecosystems, and enhance biodiversity across various regions of the Kingdom.

The releases carried out by the center over the past years included more than 80 priority wildlife species, including reem gazelles (sand gazelles), Arabian oryx, Idmi gazelles, mountain ibex, houbara bustards, ostriches, and sandgrouse, as part of efforts aimed at supporting the recovery of natural populations of these species and enhancing their sustainability within their environmental and historical ranges, SPA reported.

CEO of NCW Dr. Mohammad Qurban noted that release operations are among the key tools for restoring ecosystems and reducing ecological imbalance, as the return of wildlife to their natural habitats contributes to protecting biodiversity and improving environmental quality, which in turn supports habitat integrity, the continuity of plant and animal components, and the enhancement of ecosystem functions over the long term.

NCW continues to implement its strategic plans to develop wildlife, protect endangered species, and enhance the efficiency of natural habitat management through expanding breeding programs, enhancing applied scientific research, building national capacities, and applying the best international practices in biodiversity management, in addition to raising environmental awareness, engaging local communities, and supporting eco-tourism, thereby contributing to achieving the objectives of the Saudi Green Initiative and Saudi Vision 2030, and the National Environment Strategy, toward thriving and sustainable wildlife, biodiversity, and ecosystems.
