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 ...

Contact calling in context: intra- and intergroup variation in vocalization rates depend on a call’s function
(2020)
To maintain group cohesion while coordinating group movements, individuals might use signals to advertise the location of a route, their intention to initiate movements, or their position at a given time. In highly mobile ...
Measurement of the probability of call completion with the Dirac-Delta convolution
(Institute of Electrical and Electronics Engineers Inc., 2016-10)
We propose the formalism of the Dirac-Delta functions with polynomial argument to measure the probability of call completion (PCC) which plays an importance role in the development and assessment of the telecommunications. ...
Advertisement call of Brachycephalus albolineatus (Anura: Brachycephalidae)
(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 ...
Modeling and Monte Carlo simulation of call completion success probabilities under the input-output scheme
(Institute of Electrical and Electronics Engineers Inc., 2016-11)
We present a model of Probability of Success Call Completion (PSCC) from a typical I/O procedure and computationally tested through Monte Carlo simulation with Gaussian profiles. Under the I/O view the input and transfer ...
Ontogeny of an interactive call-and-response system in Spix's disc-winged bats
(2020)
We investigated the ontogenetic changes of two call types, the inquiry call and the response call, which comprise an interactive communication system in Spix's disc-winged bats, Thyroptera tricolor. We documented structural ...
Functional itô calculus, path-dependence and the computation of greeks
(EMAp - Escola de Matemática Aplicada, 2015)
Dupire’s functional Itˆo calculus provides an alternative approach to the classical Malliavin calculus for the computation of sensitivities, also called Greeks, of path-dependent derivatives prices. In this paper, we ...
The differences in transmission properties of two bird calls show relation to their specific functions
(2016)
When vocalizations transmit throughout the environment, attenuation and degradation may change the information of the signal; the loss of information is related to changes in both frequency and duration of vocalizations. ...
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 ...
