1. As florestas tropicais são conhecidas por seus sons bonitos e relaxantes, mas podem essas paisagens sonoras serem usadas para medir as mudanças na condição da #floresta? Um fio
2. Pesquisar #biodiversidade na Amazônia é muito difícil - há muitas espécies raras, muitas espécies difíceis de detectar, muitos perigos para os topógrafos e a floresta tropical é muito, muito grande! Image
3 Felizmente, muitos animais anunciam sua presença emitindo sons. Usamos esses sons (biofonia), juntamente com o ruído humano (antropofonia) e sons da paisagem(geofonia) para aprender mais sobre a ecologia da floresta - um campo de pesquisa relativamente novo chamado #ecoacustica Image

1.#tropicon Estimating bird diversity in tropical forests is hard. We looked at whether using lots of short surveys (high temporal resolution -HR) is more effective than several long surveys when conducting point-count surveys with autonomous recorders and manual analysis.
2. #tropicon We compared bird species detected by @NargilaMoura analysing 240 x 15 second audio clips (HR) against 4 x 15 minute samples (low res - LR) from 29 Amazonian @RAS_network rainforest sites – both totalling 1 hr of data. Illustrative model below: Image
3.#tropicon We found that HR sampling results in many more species being detected – approximately 50% more species at each site (HR= 66.27±3.77 (SE), LR= 43.37±3.77) and 10% higher gamma diversity! Species were also detected faster using HR sampling. #ornithology #ecoacoustics Image
