Abstract
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.

Abstract
Descriptions of amphibian habitat, both aquatic and terrestrial, often include plants as characteristics but seldom is it understood whether and how those plants affect amphibian ecology. Understanding how plants affect amphibian populations is needed to develop strategies to combat declines of some amphibian populations. Using a systematic approach, we reviewed and synthesized available literature on the effects of plants on pond-breeding amphibians during the aquatic and terrestrial stages of their life cycle. Our review highlights that plant communities can strongly influence the distribution, abundance, and performance of amphibians in multiple direct and indirect ways. We found three broad themes of plants' influence on amphibians: plants can affect amphibians through effects on abiotic conditions including the thermal, hydric, and chemical aspects of an amphibian's environment; plants can have large effects on aquatic life stages through effects on resource quality and abundance; and plants can modify the nature and strength of interspecific interactions between amphibians and other species - notably predators. We synthesized insights gained from the literature to discuss how plant community management fits within efforts to manage amphibian populations and to guide future research efforts. While some topical areas are well researched, we found a general lack of mechanistic and trait-based work which is needed to advance our understanding of the drivers through which plants influence amphibian ecology. Our literature review reveals the substantial role that plants can have on amphibian ecology and the need for integrating plant and amphibian ecology to improve research and management outcomes for amphibians.

Abstract
Advertisement calls potentially represent honest signals for delimiting species and sexual selection. Quantitative statistics of individual variation in advertisement call properties can be used to predict female preferences for particular signal properties. In this study, advertisement call properties and their individual variation was analyzed in two endemic treefrog species, Liuixalus hainanus and L. ocellatus. Together with the description of the advertisement calls, our goals included determining whether call properties can be used to distinguish between the two species on the field, which acoustic properties are likely play a role in species or individual recognition, and whether they could predict the signaler's body size. We found that the dominant frequency, call duration, inter-call interval, and note number of monosyllabic calls in L. hainanus were significantly higher or longer than those in L. ocellatus. The dominant frequency was classified as a static property; the call duration, inter-call interval, inter-note interval, and note number were classified as dynamic properties in both species. The inter-note interval of multisyllabic calls was correlated with body mass, and the pulse number of monosyllabic calls was correlated with snout-vent length in L. ocellatus. These results indicate that the dominant frequency strongly contributed to species recognition of L. hainanus and L. ocellatus males. Acoustic properties reflected the signaler's body size in L. ocellatus but did not in L. hainanus. The difference in advertisement call characteristics between the two species may be due to the different reproductive strategies associated with different selection pressures and may promote the sharing of similar habitats by the two species.

Abstract
ABSTRACT Climatic conditions and microhabitat characteristics, such as the substrate and type of vegetation, influence the choice of male anurans for calling sites that optimize their reproductive success. We evaluated the structure and selection of vocalization microhabitat of 17 individuals of Phyllomedusa distincta Lutz, 1950 and 25 of Boana leptolineata (Braun & Braun, 1977), in a subtropical forest in southern Brazil. We measure the height of the perch, the distance between the perch and the edge of the body of water and the structure of the microhabitat of quadrants used by individuals. The same attributes were measured in the quadrants available (but not used) by the individuals. We classified the microhabitats by visual estimate, assigning percentages of coverage for each quadrant by herbaceous, shrub, tree and wetland vegetation. We observed that both species selected their microhabitat, since the characteristics of the quadrants occupied by the individuals were different from those available. Phyllomedusa distincta was more associated with heterogeneous microhabitats, while B. leptolineata occurred in environments with greater coverage of tree strata. Additionally, we observed that both species used shrubs more frequently as a perch site. The selection of these microhabitat characteristics must be associated with strategies to optimize the use of the reproductive habitat, based on the morphological and behavioral characteristics of the species. Finally, it is possible to infer that the differences observed in the microhabitat structure selected by the species can facilitate the coexistence of both in the context of the heterogeneity of the environment.

Abstract
Abstract
Acoustic segregation is a way to reduce competition and allows for species coexistence within anuran communities. Thus, separation in at least one acoustic niche dimension is expected, which also contributes to achieving effective communication among frogs. Here we studied an assemblage of five terrestrial egg-laying anuran species, all in the genus Eleutherodactylus, in a montane rainforest in eastern Cuba. Our aim was to determine if partitioning exists between these species in any dimension (time, signal frequency or space) of the acoustic niche. The studied assemblage had the following characteristics: (1) there was one diurnal species, two species with calling activity throughout the day and two species that call at night; (2) only two species overlapped in call frequencies and most had different calls, both in terms of dominant frequencies and in temporal characteristics; and (3) males of the species that overlapped in vocalizing time or signal frequency used different calling microhabitats or heights. This study provides evidence for the acoustic niche hypothesis in anurans, showing low probabilities of interference in sound communication among these frogs. The five species were separated in at least one of the three acoustic dimensions (calling time, frequency and site) as it occurs in mainland communities with more sympatric species of several genera. Conversely, species in single-genus communities studied in Puerto Rico overlapped completely in calling times. This seems to be due to the higher number of sympatric species at our site.

Abstract
Individuals in acoustic communities compete for the use of the sound resource for communication, a problem that can be studied as niche competition. The acoustic niche hypothesis presents a way to study the partitioning of the resource, but the studies have to take into account the three dimensions of this niche: time, acoustic frequency, and space. I used an Automated Digital Recording System to determine the partitioning of time and acoustic frequency of eight frogs of the genus Eleutherodactylus from Puerto Rico. The calling activity was measured using a calling index. The community exhibited no temporal partitioning since most species called at the same time, between sunset and midnight. The species partitioned the acoustic frequency of their signals, which, in addition to the microhabitat partitioning, can provide some insight into how these species deal with the problem. This data also suggest that monitoring projects with this group should take place only before midnight to avoid false negatives.

Abstract
A correta identificação de espécies normalmente é um obstáculo para estudos de conservação, manejo e licenciamento ambiental. Atualmente 37 espécies de cinco famílias de anfíbios anuros são registradas na área que abrange integralmente as Unidades de Gerenciamento dos Recursos Hídricos (UGRHIs) do Turvo-Grande e São José dos Dourados e parte das UGHRIs do Baixo Pardo, Baixo Tietê e Tietê-Batalha. Embora esta fauna venha sendo objeto de estudos quase ininterruptos desde a metade da década de 1960, nenhuma chave de identificação que incluísse todas as espécies reconhecidas na região estava disponível. Embora desenvolvida para uma anurofauna regional, esta chave tem ampla aplicação porque as espécies encontradas na área de abrangência do estudo são associadas à áreas abertas e apresentam ampla distribuição geográfica. Este estudo visa preencher esta lacuna e apresentar uma lista ilustrada e uma chave dicotômica artificial para as 37 espécies de anuros conhecidas para esta região.

Abstract
We hypothesized that the environmental heterogeneity of breeding ponds influences the species composition and species richness of anuran assemblages from southeastern Brazil, because it provides humidity, shelter, and breeding microhabitats for anuran species, which can result in an increasing number of species in a given habitat. To begin, we tested whether the occurrence of anuran species in each breeding pond is different from a null model of random placement of species in those ponds. We then performed two tests to evaluate which of the five environmental descriptors of breeding ponds influence (1) the species composition and (2) species richness. Species composition of the 38 breeding ponds was correlated with number of edge types, number of plant types along the edges of the breeding ponds, and the hydroperiod. Neither the percentage of vegetation cover on the water’s surface nor the size of the breeding ponds were correlated with species composition. Only the number of edge types was correlated with species richness of breeding ponds. The correlation of three environmental descriptors with species composition and one environmental descriptor with species richness, as well as the high beta diversity among breeding ponds, suggest that the analyses of environmental heterogeneity on species composition was more informative than was the analysis for species richness, because breeding ponds with similar species richness can have distinct species composition among them (high beta diversity).

Abstract
O sítio de vocalização e os parâmetros acústicos do canto de anúncio foram determinados para 18 espécies de anuros em seis corpos d'água na região noroeste paulista. A freqüência dominante do canto de anúncio foi positivamente correlacionada com o CRC das espécies: as espécies pequenas vocalizaram em uma freqüência mais alta e as maiores vocalizaram em uma freqüência mais baixa. A similaridade nos parâmetros espectrais e temporais do canto de anúncio foi alta entre 94% das espécies registradas. A similaridade no uso do sítio de vocalização foi baixa, apenas 22% das espécies apresentaram alta sobreposição, apesar de cerca de metade das espécies terem sido generalistas no uso de sítio de vocalização. Analisando conjuntamente a similaridade no uso de sítio de vocalização, no hábitat e nos parâmetros do canto de anúncio, a proporção de espécies com alta sobreposição diminui de 94% para 11%, correspondente à sobreposição entre um único par de espécies: Dendropsophus elianeae e D. minutus. Espécies com sobreposição no sítio de vocalização apresentaram segregação nos parâmetros acústicos e, espécies com sobreposição nos parâmetros acústicos tenderam a partilhar sítio de vocalização. Esse resultado sugere a ocorrência de complementaridade de nicho, pois as espécies que ocuparam uma posição similar em uma dimensão tenderam a diferir em outra dimensão. A homogeneidade estrutural dos corpos d'água, a severidade climática da região e o elevado grau de conversão do ambiente natural em áreas de cultivo limitam a abundância das populações e a riqueza de espécies. A baixa sobreposição no sítio de vocalização está, provavelmente, associada a insaturação das comunidades amostradas.
