Canto territorial de Dendropsophus elegans (Wied-Neuwied, 1824) e Pithecopus gonzagai (Andrade, Haga, Ferreira, Recco-Pimentel, Toledo, Bruschi, 2020) em um fragmento de Mata Atlântica no Nordeste brasileiro

Abstract

Vocalization has a role of mating and territory delimiters and are influenced by environmental variables. Bioacoustic is an effective tool for animals to communicate primarily through sound. Territory calls limits competition for females and territories, and physical disputes. Pithecopus gonzagai and Dendropsophus elegans have only their advertisement call described. The present study aims to: [1] Describe the territory call of Dendropsophus elegans; [two]. Describe the territory song of Pithecopus gonzagai. The study was carried out at the Tapacurá Ecological Station, located in the state of Pernambuco, using a remote audio recorder with scheduling functions between 2019 and 2020. The acoustic parameters of Pernambuco investigated were: Environmental data were recorded through a Datalogger. Twenty records were analized using Audacity software, and the graphics were generated using Raven. The acoustic parameters investigated were: average call duration; interval between calls, pulses per call, minimum frequency; maximum frequency; dominant frequency and Frequency amplitude. The territory calls of D. elegans and P. gonzagai is formed by a single multipulsed note as well, after or in response to the advertisement call or the presence of other males. Bioacoustics is an important tool for monitoring studies, as well as more studies on how species-specific vocalizations, as defined long-term data to understand the main factors that present as characteristic calls.
