Monica was retamosa In the middle of the battery of the tape recorder, he heard Belberd for the first time. Standing on the floor of a forest he looked at the tree, scanned for its source Metallic and powerful wordsFinding a half -hour bird has no profit. Belberd sings from Treatps where it is visible to its peers but disappear to the people below. Nevertheless, Retamosa smiled: He listened to them in Costa Rica’s Amestosa Biological Corridor and cared for the ecosystem.
In nature, living things use words for almost everything. They call to attract companions, contact identity, to warn about danger, guide the way, and to assist in hunting or defense. For decades, researchers have tracked and still track the species, including recorders in hand, though are also increasingly using remote recording devices. Known as the study of words done by organisms BioecticsThe Retamosa has been doing this for 10 years.
Using bioccastic recording, research has shown that some birds shout loudly to listen to cities and the sea turtle hatchings communicate from home to adjust their hatching. And when biological words are combined with other words – it is made by humans, as well as the natural sounds of landscapes to crash such as the waves of the sea – it is possible to explain deep environmental meaning. It is possible to monitor biodiversity changes, to measure the effectiveness of threatening identification and conservation techniques. This greater analysis of the word is known as ecoocustics – and it is just here to work on the Costa Rica.
Ratamosa has been working for 20 years in the National University of Costa Rica, international conservation and wildlife management. He uses bioActics and ecocustics to investigate the words of this small American country hosted by more than half million species.
“The words have forgotten from the preservation point of view,” said Retamosa. “Most of the time, we hear more than us. This is probably that when there is a hassle on the system, we can detect it shortly than other reasons by a word or lack of it. “
The development of automatic recording revolutionized the BioActics and Ecocustics. Now, research groups can hang sensors that record the snipts of the day for several months at once without interfering with wildlife. Retamosa loves this technique because it is not aggressive to animals, it makes it easier to get ear and earn ears in large areas and help to discover occasional mysterious species.
Although he prefers to observe the ecosystems from afar, Retimosa will still have to go deep into the forest to set up a recorder. Visits in the field are attractive, but never rode on Sunday. He extended miles through mud and branches, including his colleague Jimmy Barrants and Randal Gymnas. They have gone up to endless OP. Once, he fell and broke his ribs. But the work does not end with installation: they have to go back to change their battery and memory card. In other countries, they use solar panels and the Internet to get real-time data; In the dark of Costa Rica, in the moist rain forest, it is still done by hand.
