Costa Rica saves forest ecosystems by listening to them

Monica was retamosa In the middle of the batteries of a tape tape when you hear a bellbird for the first time. Standing on the forest floor, he looked at the crawl trees for the source Metal and strong soundlooking for a half-hour bird without any results. Bellbird reads from the unseen treetops that appears to their peers but not visible to the following. Again, Retamosa smiled: Costa Rica listens to the amistasa’s ecosystems in the biological corridor.

In nature, creatures use the sound for almost everything. Take calls to attract personalities, to attract personalities, to lead the dangers, to guide the road and help hunting or defense. For decades, researchers watched the types with the recorders in his hand and still use remote-note equipment. Study of sounds is known as making organisms bioacoustics. Retamosa is doing this work for 10 years.

Using bioacustic articles, research showed that some birds are loud to communicate from the nest to coordinate the nest in the cities and coordinated the sea turtle head. And bioacustics are possible – people are developed by other voices, as well as the voice of the landscape, for example, the deep environmental meaning of natural sounds such as the collapse of sea waves. It is possible to monitor changes in biodiversity, detect threats and effectiveness of protection strategies. This wider analysis of the sound is known as ecocustics and here in Costa Rica continues exactly here.

Retamosa has been working for 20 years at the International University of Costa Rica, International Security and Wildlife Management Institute. It uses bioacustic and ecacoustics to explore the votes of this small Central American country, which has more than half a million species.

“Sounds were forgotten in terms of conservation,” said Retamosa. “We hear more than we have seen more often. It is likely that when a discomfort in the system occurs, we can quickly detect it quickly by a voice or absence of other factors.”

The development of automated articles has revolutionized bioacustics and ecacoustics. Now research teams can hang sensors that celebrate the pieces of days during the day without interference with wildlife. Retamosa likes this strategy because animals simplify the presence of ears and difficult places in large areas, and sometimes help to discover mysterious species.

Although it prefers to follow the ecosystems from a distance, Retamosa should still go deep to the forest to set up notes. Trips to the field are interesting, but it is never a trip to Sunday. Jimmy Barrantes and Randall Jiménez walked several kilometers from mud and branches along with Jiménez. Infinite slopes went up and down. Once, he broke and broke his ribs. However, the work does not end with installation: they must return to change batteries and memory cards. Other countries use solar panels and real-time information from the Internet; In the dark, the damp rainforests of Costa Rica are still handed by hand.
