Costa Rica is that wasting the forest ecosystem to hear them

RETAMINA Monica was In the middle of changing the batteries of a tape record when he heard a Bellbird for the first time. Standing on a forest floor, lifted in the trees, scanned for the source of his metallic and powerful soundlooking for the bird for half hour to anyone. Bellbird Cings from the teletops where visible to their parysis but invisible to those below. However, retamosa smiled: she cares of the ecosystem to biological corridor of the Costa Rica to hear.

In nature, living things uses sound for almost everything. They make the calls to attract mate, communicate identity, adjustment of hazards, drive the road, and helps in chase or defense. For decades, researchers have special tracks with hand registrations, and even as long, always consignment of remote registration. The study of sounds that make organisms that are known as Biiacusticci. I am Retamosa has done this job for 10 years.

Use biooacuounic recordings, studies are displayed that some birds mingle strong to make them feel in town and that the tartarle marine communicates from the nest by coordinating their squares. And when he is combined with other sounds – those facts of men, as the natural man’s natural man, like waves crash in the sea of ​​their deepest mean. It has become possible of monitor changes in biodiversity, redge threat, and measure the efficiency of conservation strategies. This sound analysis is known as ecoacoustic – and is exactly work on course here in Costa Rica.

Retamosa has worked for 20 years on National Costa Costa University, in the international window of the wild window and management of life. ISA uses bioacoustic and Equacustics to investigate the sounds of this small central American country that host more than one half of species.

“Sounds were forgotten from a conservation point of view,” retamous says. “Most of the time we are more than we see. It is likely to be in the disturbance is found in the system, we can pick it up a sound, or missing case, than other factors.”

The development of automated revisitioned revisitioned and ecoacustic revisition. Now, search groups can hang the sensors that registered the snippets of the day for months on time without interfering with wildlife. Retamosa I like this strategy because it is not invased for animals, wake up to the ears of hard hard, and understanding you aimsively discomfort.

Even if you prefer the monitoring the ecosystem from a distance, retamous, it even go deep to the forest to create recorders. The visits in the field are charming, but never a mistaken Sunday. He changed miles up to fang and branches, with his jimmy barrants and randall jiménez. They are crowned and down in endless tracks. Once, she is down and fracluid his nerves. But work does not finish with the installation: they should return to change the memory batteries and cards. In other countries we have solar panels and the internet to receive real-time data; In the dark, wet coastboards of the rica, it’s always done by hand.
