Dendropsophus novaisi (Bokermann,1968) was described from Maracás Municipality, State of Bahia, Brazil. Since its description, the species has been reported for one additional location in the State of Minas Gerais (Pedra Azul - Gomes & Peixoto 1996; Peixoto & Pimenta 2004) and five additional locations in Bahia (Boa Nova, Jequié, Jeremoabo, Camacan and Pau Brasil - Gomes & Peixoto 1996; Santos-Silva et al. 2012; Silva et al. 2013; Dias et al. 2014). However, information is still scarce about reproductive, ecological and acoustic characteristics of this treefrog. Here, we describe the advertisement call of D. novaisi and provide the geographic record of a new population.

A list of amphibian and reptile species that occur in open and forested areas of the Atlantic Forest in the municipality of Cruz das Almas, in the Recôncavo Baiano, eastern Brazil is presented. Field sampling occurred between January 2015 to March 2019, totalling 117 samples distributed in three areas: Parque Florestal Mata de Cazuzinha, Mata da Cascalheira, and Riacho do Machado. A total of 1,848 individuals of 69 species (31 anurans, 14 lizards, 19 snakes, two amphisbaenians, and three testudines) was recorded. Additionally, one individual of Ophiodes striatus was found in Mata da Cascalheira after the end of sampling, totalling 15 lizard species and 70 herpetofaunal species. The prevalence of open-area species and the presence of Phyllopezus lutzae, Diploglossus lessonae, and Dryadosaura nordestina in interior forest patches are discussed. Additionally, a new record of the invasive terrapin Trachemys dorbigni in the State of Bahia is reported.

In this study we investigate the niche interaction between the frogs Physalameus cuvieri and Physalaemus kroyeri that occur in syntopy in water bodies of the Atlantic Forest located in the eastern Bahia State, Brazil. We investigated the niche width and overlap in the calling activity time, microhabitat use, diet composition, advertisement call, and body size. Both species preferred the same substrate and calling substrate categories, and showed low niche width values and high spatial niche overlap values. The pseudocommunity analysis revealed the absence of competition in space use. Ants and termites were the most important items in the diet of both species with the pseudocommunity analysis indicating an absence of competition in the diet. The two species demonstrate a greater similarity in body proportions and a high overlap in the calling activity time. However, they showed divergence in acoustic parameters, especially in the dominant frequency and call duration. Our results reinforce the role of advertisement call as a relevant attribute for anuran coexistence and highlight the importance of analyzing the various axes of the multidimensional niche for the most reliable description of the existence and magnitude of niche partitioning.
