Resumo: | Ameerega braccata is an aposematic, small dendrobatid anuran known from its type-locality, Chapada dos Guimarães, in the State of Mato Grosso, and from a few additional localities in Mato Grosso do Sul and Goiás States, Brazil. The advertisement call of A. braccata is composed of a single unpulsed note, with a frequency range from 3.5 to 4.2 KHz (N = 110), and average duration of 65.8 ms (N = 110, SD = 11.6). The territorial call is composed of five or six repeated notes, structurally similar to advertisement call notes. The courtship call is emitted in close-range interactions between male-female during the courtship event and may reach frequencies of 2.2 to 5.3 KHz (N = 10), with shorter notes (average duration 43 ms; N = 10; SD = 4.9). Call duration, note duration and call rate of the advertisement call showed high variation (>15% of coefficient of variation), and dominant frequency showed low variation (<4%). The properties with higher variation possibly respond to climatic features and male social position. When producing advertisement calls, males were usually found at an average height of 31.4 cm (N = 19, SD = 12.2 cm), mainly on leaves of shrubs and herbaceous plants (59%). Individuals of A. braccata were found in open physiognomies in the Cerrado ("campo sujo" and "cerrado stricto sensu"), as opposed to that found by previous researchers, who reported an association of the species with gallery forests in the Cerrado. |
