“…A summary of larval characteristics for tadpoles of H. punctatus group is given in table II. The external larval morphology of the H. punctatus group is similar and resembles that of a generalist type larvae (ALTIG & JOHNSTON, 1989). These characteristics include: body depressed in lateral view, caudal musculature not strongly marked, low caudal fins, and eyes dorsolaterally located, agree with the ecomorphological guild of benthic tadpoles that live in lentic environments.…”

ABSTRACT. The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining the status of these populations.

“…sibilatus, A. cavicola and B. capra (Mercês et al 2011) can be considered benthic tadpoles (Altig & Johnston 1989), a guild characterized by Wells (2007) as having general eating habits. The results of this study confirmed similarity in eating habits but also illustrated differences according to NMDS analysis, which could be the result of resource allocation.…”

“…Tadpoles are considered specialized filter feeder herbivores (Duellman & Trueb 1994), as they consume a large variety and quantity of algae, especially in the early stages of their development (Wickramasinghe et al 2007). However, tadpoles can also consume protozoa, fungi and microscopic animals available in their habitat, which characterizes them additionally as omnivores (Altig & Johnston 1989).…”

“…This scenario suggests that in a given community of tadpoles, food resource allocation may be detected indirectly through the different ecomorphotypes (sensu Altig & Johnston 1989) of these organisms. Each ecomorphotype is associated with a specific microhabitat and utilizes different food resources, which are also associated, therefore, with the respective microhabitat (Rossa-Feres et al 2004).…”

The study of the diet of tadpoles can provide important information about the maintenance and dynamics of populations and communities of tropical amphibians. Tadpoles are in general herbivores and consume mostly algae. Despite this, little is known about how specific guilds use resources that are available in the same space and at the same time. It is thought that species of tadpoles segregate based on food use, especially in lotic environments where food resources may be a limiting factor. Conversely, it is believed that the use of food resources is similar among tadpoles with the same ecomorphotype. This study examined the diet of Aplastodiscus cavicola, Aplastodiscus sibilatus and Bokermannohyla capra syntopic tadpoles, as similarities may exist between these benthic species, all of which are adapted to the flow of water. This study was undertaken in the Michelin Ecological Reserve, municipality of Igrapi una, state of Bahia, Brazil. To analyze the diet of the tadpoles, nonmetric multidimensional scaling (NMDS) was performed to evaluate the similarity between the diets of the species. Analysis of similarity (ANOSIM) was carried out to detect whether diet differed among tadpole species. The diet of these tadpoles consists mainly of algae, especially diatoms, plants, protozoa, fungi and microscopic animals. The NMDS identified three clusters representing the three species studied. ANOSIM detected significant differences among the diets of the species, which indicates partition of food resources.

“…It should be noted that Wassersug & Pyburn (1987) and Altig & Johnston (1989) pointed out that the teeth in tadpoles of Otophryne are homologous to the jaws or beaks, rather than denticles, of other tadpoles.…”
