FIGURE 1 in Frog assemblage associated with bromeliads in a sandy coastal plain in the state of Espírito Santo, southeastern Brazil
FIGURE 1: Location of Parque Estadual Paulo César Vinha (black dot) in the state of Espírito Santo, southeastern Brazil (A) and sampled sites: rocky outcrop (B), open shrub vegetation (C), both in the mainland, and open herbaceous vegetation in coastal island (D). States are Bahia (BA), Espírito Santo (ES), Minas Gerais (MG) and Rio de Janeiro (RJ).
Fig. 1 in Helminth's assemblage of a small frog in the Brazilian semiarid: parasite-host-environment relationships
Fig. 1. Parasite load (total number of helminths per host) between females (N= 41) and males (N= 53) of Pseudopaludicola pocoto (Anura) from AssÚ municipality, Rio Grande do Norte state, northeastern Brazil.
Figure 3 in Factors influencing spatial and temporal structure of frog assemblages at ponds in southeastern Brazil
Figure 3. Distribution of nine tadpole species within ponds at Santuário do Caraça, southeastern Brazil, according to variables used to describe microhabitats used by them and period of occurrence, in the first three axes of discriminant space. In the first discriminant axis, smaller values represent larger association to the bottom. In the second axis, the largest values indicate use of deeper microhabitats by tadpoles. In the third axis, larger values indicate species that used both microhabitats with and without aquatic vegetation, and lower values indicate species that used only microhabitats with aquatic vegetation. Centroids for each species are shown on the right.

Figure 2. Distribution of adult individuals of 22 anuran species at Santuário do Caraça, southeastern Brazil, according to variables used to describe microhabitat use and activity periods, in the first three axes of the discriminant function. Centroids for each species are shown on the right.
Species abundances and functional traits data of frog assemblages in Amazonian forests (Tapajós FLONA and Alter do Chão village, Brazil)
<p>We sampled frogs along an edaphic and vegetation-structure gradient in the Brazilian Amazon. We sampled 33 plots organized in four modules (with 10, 6, 8 and 9 plots). Environmental data are composed of are litter depht(cm), distance to water bodies (m), temperature (ºC), vegetation structure (PCA axis), soil sand and silt content (g-kg), and proportion of the area deforested. Additionally, we measured snout-vent length (SVL) and leg length relative to SVL and evaluated the effects of environmental variables on thirteen binary traits used with presence or absence.</p>
Figure 1 in The effects of environmental cues on chorusing onset in a tropical frog assemblage
Figure 1. Ambient light level at first call* by tropical frog species, Gamboa, Panama. Groupings A, B, C are based on results from Tukey's HSD test with similarly behaving species grouped together. Box plots represent quartile ranges for each species. *CF1 refers to onset of Craugaster fitzingeri, CF0 refers to cessation of calling by C. fitzingeri. DE – Dendropsophus ebraccatus, DD – Diasporus diastema, SB – S. boulengeri, DM – Dendropsophus microcephalus, RA – R. alata, BR – B. rosenbergi, PT – P. taeniatus, AC – Agalychnis callidryas.

Links between prey assemblages and poison frog toxins: a landscape ecology approach to assess how biotic interactions affect species phenotypes
<p>Ecological studies of species pairs showed that biotic interactions promote phenotypic change and eco-evolutionary feedbacks. However, it is unclear how phenotypes respond to synergistic interactions with multiple taxa. We investigate whether interactions with multiple prey species explain spatially structured variation in the skin toxins of the Neotropical poison frog <i>Oophaga pumilio</i>. Specifically, we assess how dissimilarity (i.e., beta diversity) of alkaloid-bearing arthropod prey assemblages (68 ant species) and evolutionary divergence between frog populations (from a neutral genetic marker) contribute to frog poison dissimilarity (toxin profiles composed of 230 different lipophilic alkaloids sampled from 934 frogs at 46 sites). We find that models that incorporate spatial turnover in the composition of ant assemblages explain part of the frog alkaloid variation, and we infer unique alkaloid combinations across the range of <i>O. pumilio</i>. Moreover, we find that alkaloid variation increases weakly with the evolutionary divergence between frog populations. The analytical framework proposed here can be extended to other multi-trophic systems, coevolutionary mosaics, microbial assemblages, and ecosystem services.</p>
