Scientists get creative to continue research during pandemic

Covid-19 abruptly halted research for many scientists globally. Some have had to innovate and look for alternatives

San Lorenzo, Panama: Biologist Claudio Monteza pushed through thick vegetation to install a camera near a Panamanian highway in a dense tropical rainforest. Securing the device to a tree just off the forest floor, he checked its field of vision.

The camera and others were set up to provide insights into which animals steer clear of highways and which ones are more apt to check them out. The findings could someday help transportation officials better protect wildlife in one of the world's most biologically diverse environments.

But the highway study “was not the initial plan,” said Monteza, whose career was upended last year when COVID-19 stranded him in his native Panama and suspended his research. Because of the pandemic, many scientists "have had to innovate and look for alternatives.”

The coronavirus abruptly halted research by many Latin American scientists, interrupting field work, sample collection and laboratory experiments. Some of them could focus on writing scholarly articles based on previous research, but others had to get creative to avoid losing a year of their careers.

Monteza had just finished a master’s degree in the United States when he stopped in Panama for a few days before a planned flight to Germany to begin his doctoral studies. Then the world began shutting down. He started taking doctoral classes virtually.

After governments adopted strict quarantine measures, Monteza concluded that one way to get permission for research was to look at highways because they could be studied without significant travel.

Other scientists hauled samples of marine sediment and lab equipment or even entire ant colonies into their homes. One researcher, barred from capturing bats to bring to her laboratory, mounted cameras that allowed her to spy on their sexual habits in the wild.

On a recent day, after installing one camera, Monteza pushed about 50 yards deeper into the forest. Field biologist Pedro Castillo helped him install another camera just as heavy raindrops began to fall. In minutes, both men were soaked, but the opportunity to get into the field was a relief.

Monteza believes the highway research could help push authorities to create wildlife crossings for armadillos, the rodents known as lowland pacas and agoutis, and other animals.

During the first half of 2020, when Panama was under an absolute quarantine, scientists had almost “zero mobility, said Erick Núñez, head of the Panama Environmental Ministry’s biodiversity department. "There was very little research.”

Later, the Health Ministry began to loosen restrictions and granted passes to some scientists who planned to work in protected areas alone or in small groups, Núñez said.

Researcher Brígida De Gracia of the Smithsonian Tropical Research Institute was lucky to be able to work from home. She had collected sediment samples in 2018, 2019 and January 2020 that allowed her to continue her research during the pandemic.

But to do so, De Gracia took the samples, a stereoscope, vials, a scale and many books home from her lab in Naos, near where the Panama Canal meets the Pacific Ocean.

De Gracia studies otoliths, tiny stone-like structures in the ears of many vertebrates. In particular, she studies them in fish to see how humans have affected fish over the past several thousand years.

“You have to store them very carefully,” because they’re so tiny that even a light breeze can move them, said De Gracia, who analyzed and photographed the otoliths at home.

Before the coronavirus arrived, Mariana Muñoz-Romo, a post-doctoral researcher at the Smithsonian, had planned to capture a large sample of bats from different places around the Panamanian town of Gamboa, but the suspension of research activities made that impossible.

So she adjusted. Instead of catching bats to take back to a lab, Muñoz-Romo shifted to observing the bats’ sex lives in their own habitat. She hopes to discover the purpose of a strong-smelling substance on the forearms of the fringe-lipped bat.

Her mentor was able to get permits to install video cameras and other devices in a bat sanctuary in Gamboa. They started recording in mid-2020 and plan to continue for several more months.

“Analyzing these recordings is fabulous because you can generate a mountain of information,” said Muñoz-Romo, a Venezuelan who is a professor at the University of the Andes in Merida, Venezuela.

Dumas Galvez, a researcher of the Smithsonian Tropical Research Institute, collects ants from a nest in Paraiso, Panama, Tuesday, April 13, 2021. Before the COVID-19 pandemic, Galvez spent many hours in his lab analyzing their blood and how they responded to attacking fungi.

When the pandemic closed his laboratory in Gamboa, Dumas Gálvez moved dozens of colonies of ants to his home in Paraiso. He wanted to continue observing them as part of his research into their immune systems.

Before the pandemic, that required many hours in his lab analyzing their blood and how they responded to attacking fungi.

“I had to look for alternatives,” Gálvez said. “And one of the alternatives was initially to do it in my house.”

Gálvez outfitted an extra bathroom to hold up to 100 ant colonies. His largest colonies were around 200 ants, so he had an estimated 13,000 ants in his home.

He observed their lives and reactions for months, but over time they began to die. Exactly why was not clear. It was either because of the fungus or excessive heat, he said.

“The conditions in the bathroom were not optimal," he said. "It was very hot. They dried quickly.”

The pandemic prevented him from going out to collect more ants, so he shifted his focus and is now studying the interaction of ants and a small predatory frog.

Panama has since eased its pandemic restrictions, and the Smithsonian is reopening its facilities there. Gálvez has been able to resume field work and supervising students.

“If not for the pandemic, I wouldn’t have invested the energy in considering alternatives,” he said. “I probably would not have ever done this project.”
