“…Multiple chambers were rare in L. mystacinus and may be related to territoriality and to a possible scarcity of proper places for chamber-digging. Besides L. mystacinus, multiple chambers were also described as a variation in L. mystaceus (TOLEDO et al, 2005;ARZABE & PRADO, 2006), L. fuscus, and L. notoaktites (Heyer, 1978 ) (ARZABE & PRADO, 2006).…”

ABSTRACT. Here we present data on the reproductive behavior of Leptodactylus mystacinus (Burmeister, 1861), including details on courtship behavior. We also describe and compared the courtship calls of L. mystacinus, L. furnarius Sazima & Bokermann, 1978 and Leptodactylus sp. (L. aff. andreae). Field works were conducted in Uberlândia (central Brazil). During courtship, a female approaches a calling male and is led to a previously excavated chamber; a female can approach a silent male that beat his hands and/or feet on the ground as well. The courtship call of L. mystacinus consists of one single arch-shaped note (duration = 0.04 s) repeated 258 times per minute; the courtship calls of L. furnarius (0.06 s, 84 times per minute) and Leptodactylus sp. (0.15 s, 5 times per minute) also are archshaped. The courtship behavior of L. mystacinus is similar to that of other species of the L. fuscus (Schneider, 1799) group; unique to it is that males can beat his hands and/or feet on the ground while courting. The male behavior of conducting the female to a previously excavates chamber and the arch-shaped courtship call may represent other shared derived features of members of the L. fuscus group, including the former Adenomera species.KEYWORDS. Brazilian savanna, foam nests, territoriality, vocalization, parental care. Brasil). Durante a corte, a fêmea aproxima-se de um macho que vocaliza e é levada para uma câmara previamente escavada; uma fêmea pode se aproximar de um macho silente que bate as mãos e/ou pés no solo repetidamente. O canto de corte de L. mystacinus consiste de uma única nota em forma de arco (duração = 0.04 s) repetida 258 vezes por minuto; os cantos de corte de L. furnarius (0.06 s, 84 vezes por minuto) e Leptodactylus sp. (0.15 s, 5 vezes por minuto) também são em forma de arco. O comportamento de corte de L. mystacinus é similar ao de outras espécies do grupo de L. fuscus (Schneider, 1799); sendo exclusivo daquela espécie o fato de que os machos podem bater suas mãos e/ou pés no solo enquanto cortejam. O comportamento do macho de conduzir a fêmea para uma câmara previamente escavada e o canto de corte em forma de arco podem representar outras características derivadas compartilhadas pelos membros do grupo de L. fuscus, incluindo as antigas espécies de Adenomera.

Multiple Quaternary Refugia in the Eastern Guiana Shield Revealed by Comparative Phylogeography of 12 Frog Species

et al. 2012

View full text Add to dashboard Cite

The Guiana Shield (GS) is one of the most pristine regions of Amazonia and biologically one of the richest areas on Earth. How and when this massive diversity arose remains the subject of considerable debate. The prevailing hypothesis of Quaternary glacial refugia suggests that a part of the eastern GS, among other areas in Amazonia, served as stable forested refugia during periods of aridity. However, the recently proposed disturbance-vicariance hypothesis proposes that fluctuations in temperature on orbital timescales, with some associated aridity, have driven Neotropical diversification. The expectations of the temporal and spatial organization of biodiversity differ between these two hypotheses. Here, we compare the genetic structure of 12 leaf-litter inhabiting frog species from the GS lowlands using a combination of mitochondrial and nuclear sequences in an integrative analytical approach that includes phylogenetic reconstructions, molecular dating, and Geographic Information System methods. This comparative and integrated approach overcomes the well-known limitations of phylogeographic inference based on single species and single loci. All of the focal species exhibit distinct phylogeographic patterns highlighting taxon-specific historical distributions, ecological tolerances to climatic disturbance, and dispersal abilities. Nevertheless, all but one species exhibit a history of fragmentation/isolation within the eastern GS during the Quaternary with spatial and temporal concordance among species. The signature of isolation in northern French Guiana (FG) during the early Pleistocene is particularly clear. Approximate Bayesian Computation supports the synchrony of the divergence between northern FG and other GS lineages. Substructure observed throughout the GS suggests further Quaternary fragmentation and a role for rivers. Our findings support fragmentation of moist tropical forest in the eastern GS during this period when the refuge hypothesis would have the region serving as a contiguous wet-forest refuge.

A new species of Leptodactylus belonging to the L. fuscus species group, and related to the L. mystaceus complex, is described from the Lagoa das Bromélias (20 o 53'S, 42 o 31'W; 1,227 m above sea level), Parque Estadual da Serra do Brigadeiro, Municipality of Ervália, State of Minas Gerais, Southeastern Brazil. Leptodactylus cupreus sp. nov. is characterized by the large size for the group (SVL 50.1-55.1 mm in males) and color pattern. The new species has a non-pulsed advertisement call, with call rate about 12 calls/s and a dominant frequency between 2,800 and 3,058 Hz. Material and methodsExamined specimens are housed at the Museu Nacional, Rio de Janeiro, Brazil (MNRJ) and Museu de História Natural João Moojen de Oliveira, Viçosa, Brasil (MZUFV). Comparative specimens are referred in the Appendix 1.Measurements were taken with digital calipers. Abbreviations of the measurements (in mm) are: SVL (snout-vent length); HL (head length); HW (head width); IND (internarial distance); END (eye to nostril distance); ED (eye diameter); UEW (upper eyelid width); IOD (interorbital distance); TD (tympanum diameter); HAL (hand length); THL (thigh length); TL (tibia length); FL (foot length). Morphological terminology follows Heyer et al. (1990).Specimens were recorded with a Panasonic RQ-L11 tape recorder on 08 October 2006, at 20 o C air temperature, by R. N. Feio. Calls were digitized from the same tape recorder to avoid velocity alterations and quality loss; and the digitized file did not present differences to the actual call when compared to hearing. Calls were digitized at a sampling rate of 22,050 Hz and resolution of 16 bits. Sound analyses were performed with the program Avisoft-SASLab Light for Windows, version 3.74 (www.avisoft.com). A sonogram was produced utilizing the following parameters: Bandwidth = 323 Hz; FFT length = 256; Frame = 100; Window = Flat Top; Overlap = 75; Time resolution = 2.90 ms; Contrast = char3.gray. Oscillograms and power spectrum of the calls were obtained with the program Sound Ruler Acoustic Analysis, version 0.9.6.0 (http://soundruler.sf.net). Terminology used for call description follows Duellman and Trueb (1994). ResultsLeptodactylus cupreus sp. nov. (Figures 1-3) Holotype: MNRJ 47752. Adult male (Figure 1).
