Resumen:
Anuran calling activity has been widely associated with abiotic factors,
such as temperature, rain and photoperiod. In this sense, mathematical
modelling could help us to decipher the mechanisms that underlie these
phenomena in order to be able to predict possible scenarios. Here, we
propose 15 models that incorporate some environmental variables with
biologic relevance: photoperiod, accumulated rain, dry/wet season, and
annual mean temperature. The calling activity patterns were obtained
with an automated recording system (ARS) for 7 months in Naha, Chiapas,
Mexico, where nine species were recorded. Those models were compared
through the Akaike information criterion corrected for small samples
(AIC(C) ) to find the one that best fits. Our results point to a
sinusoidal model containing photoperiod, dry-wet season and accumulated
rain as the best model. Photoperiod resulted as a critical variable
driving phenological calling activity patterns since whenever it was
incorporated in a model, its A I C C values were reduced. It is
interesting because the photoperiod, through photoreception, allows
anurans to synchronise their physiology and behaviour throughout the
year, being able to control the growth, development and maintenance of
organisms by starting the reproduction phases in optimal seasons for
their development. However, it is also important to highlight that
phenological structure of the anuran calls in Naha, Mexico is better
explained by a combination of mechanisms, which includes photoperiod,
rainfall and seasonality, but not temperature.
