Dual Function of Chip Calls Depending on Changing Call Rate Related to Risk Level in Territorial Pairs of White-Eared Ground-Sparrows
(2017-03)
Different mechanisms have been proposed for encoding information into vocalizations: variation of frequency or temporal characteristics, variation in the rate of vocalization production, and use of different vocalization ...

(Peerj Inc, 2018-07-20)
Background: Brachycephalus are among the smallest terrestrial vertebrates in the world. The genus encompasses 34 species endemic to the Brazilian Atlantic Rainforest, occurring mostly in montane forests, with many species ...
Advertisement and release calls of Phyllomedusa ayeaye (Anura: Hylidae) with comments on the social context of emission
(Soc Brasileira Zoologia, Univ Federal Parana, 2015-08-01)
Male calls play different roles in anuran social organization, such as spacing, territoriality and female attraction. However, calls and associated behaviors remain poorly described for many anuran species. Here we describe ...
Calling sites and acoustic partitioning in species of the Hyla nana and rubicundula groups (Anura, Hylidae)
(2006-07-01)
We analysed spatial and acoustic partitioning among four species of Hyla belonging to two species-groups: nana (H. nana and H. sanborni) and rubicundula (H. elianeae and H. jimi). Field activities were conducted at three ...
Social calls used by a leaf-roosting bat to signal location
(2010-01)
Social calls in bats have many functions, including mate attraction and maintaining contact during flight. Research suggests that social calls may also be used to transfer information about roosts, but no studies have yet ...
On the Generalized Mittag-Leffler Function and its Application in a Fractional Telegraph Equation
(Springer, 2012-03-01)
The classical Mittag-Leffler functions, involving one- and two-parameter, play an important role in the study of fractional-order differential (and integral) equations. The so-called generalized Mittag-Leffler function, a ...
On S-asymptotically omega-periodic functions on Banach spaces and applications
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
This paper is devoted to the study of the class of continuous and bounded functions f : [0, infinity] -> X for which exists omega > 0 such that lim(t ->infinity) (f (t + omega) - f (t)) = 0 (in the sequel called S-asymptotically ...
