Abstract. To understand the seasonal reproductive dynamics of Hypsiboas albopunctatus, a Neotropical treefrog, we studied the following. Diagnosis Hypsiboas albopunctatus differs from the other members of the genus by the following combination of characters: (1) modal webbing formula of the. The Hypsiboas albopunctatus species group comprises 10 species, nine of which are defined based on molecular characters (), while one new.

The Cerrados of Brazil. We also registered the number of calling males of both species in the site by acoustic identification and albopjnctatus encounters. Concerning the aggressive call, calling rate and SPL had a positive correlation and the maximum frequency had a negative correlation with body size, whereas the number of calling males was positively correlation with calling rate and call duration.

An analysis with anuran species from Bolivia. Herpetological Journal 21 1: Strabomantidae in Central Brazil. Interprets this as “Lithobates OR pipiens” so will find the union of all records that contain either “Lithobates” or “pipiens”: Canadian Journal of Zoology 82 6: The Herpetological Journal 16 3: Auletris boans — Wagler,Nat.

Hylidae and the Significance of Acoustic and Visual Signals. Hypsiboas paranaiba males emitted aggressive calls I with a higher calling rate than H. Regarding aggressive call I, the minimum frequency was negatively associated with body size and positively associated with air humidity, while SPL and calling rate were negatively associated with air temperature and positively associated albopunctatuus the number of conspecific calling males, respectively.


They may also increase note duration, repetition rate and maximum frequency according to albopunchatus increase in the SPL of other males.

New Jersey, Prentice-Hall, 4th ed. On the other hand, as found for’ the SPL aggressive call of H.

Means that the results of the search will all records that have either of the terms held together by an OR Lithobates OR “Costa Rica” Recovers all records that contain the word “Lithobates” or “Costa Rica”: There was no spatial segregation between H. Allows a partial letter string to be entered and implies either no or various extension on this letter string.

We did not include aggressive call II in the analysis because only a few individuals emitted this call.

Means that the results of the search will all records that have either of the terms held together by an OR. Recovers all records that contain the word “Lithobates” or “Costa Rica”: The types of perch, perch height and distance from the calling male to the water were similar in both species. Ptacek MB Calling sites used by male gray treefrogs, Hyla versicolor and Hyla chrysoscelisin sympatry and allopatry in Missouri.

Animal Behaviour 57 6: Although the calling behavior of H. We analyzed the temporal and spectral parameters of calls with Avisoft-Sonagraphy lite r and Cool Edit 96 r software, respectively. Recovers only records that contain the word Lithobates AND “Costa Rica”, but excludes any albopujctatus that contains the word “forreri” in any part of the record: This highlights the importance of considering different call parameters in bioacoustical studies.

Journal of Herpetology 40 2: Interprets this as “Lithobates AND pipiens” so will return all records that have the character string “Lithobates pipiens” anywhere within a record: Those changes are strategic to maximize the reproductive success of males Wells bBee et al.

New York, John Wiley. The advertisement calls of the two frogs differ in their temporal structures and their aggressive calls had different maximum frequencies.

For each individual, we analyzed five advertisement and five aggressive calls.
