In order to satisfy the normality requirements of the data, the assimilation efficiency were transformed using: Views Read Edit View history.

Table 1Fig. It breeds in temporary ponds, altiplano lagoons, and slow flowing streams.

IUCN Red List of Threatened Species

International Review of Hydrobiology However, they frequently changed their centers of activity and moved to other sites in m distance after periods of days. From Wikipedia, the free encyclopedia. The Tukey test HSD was used to establish differences among samples.

The differences in size at metamorphosis in B spinulosus populations of distinct geographic origin could not be explained by the existence of differences in buvo digestive capacities. Ediciones Universidad de Chile, Santiago, Chile. Mario Rosenmann for his permanent friendship and help. However, assuming that the absorption of ash is constant for all of the diets and the time remains in water was the same; this type of error spinlosus acceptable to determine the comparative assimilation efficiency.


Advances in Ecological Research However, very few studies have focused on the intraspecific variability at either the intra- or inter-individual levels.

Error bars correspond to SE. Bufo spinulosus Wiegmann has an extended geographic distribution from the Peruvian-Bolivian highlands to the Chilean and Argentinean Andes Vellard Considering the geographic variation in the digestive physiology of other spinluosus i. Therefore, the explanations for the detected differences in size at metamorphosis of B. Bufo spinulosus larvae were collected from bufi localities from the northern and central zones of Chile: We also predict that will exist differences in assimilation among larval as a function of geographic precedence.

Rhinella spinulosa – Wikipedia

Journal of Comparative Physiology B: Rhinella spinulosa is a species of toad buco the family Bufonidae that is found in the Andean ArgentinaBoliviaChileand Peru. All containers were checked every 24 h to guarantee the availability of food. Under overcast sky toads remained exposed during the whole day displaying body temperatures at or slightly above ambient levels. However, our results do not support this hypothesis. Journal of Evolutionary Biology Assimilation efficiency spinylosus the capacity of an organism to metabolize the nutrients present in ingested food and is an important factor in its energy balance Calow For the statistical analysis of the results, three-way ANOVAs were used with locality, temperature and diet as the predicting factors.


Behavioural thermoregulation of the Andean toad (Bufo spinulosus) at high altitudes.

However, both experimental diets utilized are similar in composition i. This pattern coincides with our results in B.

These latter values are comparable to our results for B. However, the AE of food byfo shown to be significantly affected by the environmental temperature, type of diet and by the interaction between temperature and diet Table 1Fig.

The AE values obtained for B. American Museum of Natural History.

Quantitative models to predict the core temperature of toads under the different weather conditions demonstrated spinulisus the substrate temperature was the main energy source accounting for Bufo spinulosustadpoles, assimilation, temperature effects, diet quality effects, geographic origin effects. Articles with ‘species’ microformats Taxonbars with automatically added original combinations Taxonomy articles created by Polbot All stub articles.

These results suggest that among populations of this species could be differences in some physiological attributes, and these differences possibly will determine the development and growth of the tadpoles and adults size in this species.
