Article Synopsis
- Scientists aim to uncover the reasons behind the Neotropical region's high bird diversity by examining factors like climate and human impact on morphological variation.
- The ATLANTIC BIRD TRAITS dataset includes over 67,000 bird records spanning 711 species in South America’s Atlantic forests, covering up to 44 morphological traits collected over 200 years.
- This dataset, which is the most extensive of its kind in a biodiversity hotspot, supports both basic scientific research and practical conservation efforts.
Acoustic signal production is affected by allometric relationships, by which the larger the animal, the lower its call frequency. In this paper, three evolutionary acoustic hypotheses were tested: the Signal-to-Noise Ratio Hypothesis (SNRH), in which evolution maximizes call ranges by increasing the signal-to-noise ratio; the Stimulus Threshold Hypothesis (STH), in which evolution maximizes the range of a specific signal threshold; and the Body Size Hypothesis (BSH), in which the emission of long wavelengths is enabled by body size. Three spectral metrics were measured, Dominant Frequency (FDOM), Minimum Fundamental Frequencies (FFMIN), and Maximum Fundamental Frequencies (FFMAX) of Neotropical Parrots, New World Doves, Woodcreepers, Tinamous, and Thrushes.
