CLIMATIC BREADTH OF CALLING BEHAVIOUR IN TWO WIDESPREAD NEOTROPICAL FROGS: INSIGHTS FROM HUMIDITY EXTREMES

Climate change is severely altering precipitation regimes at local and
global scales, yet the capacity of species to cope with these changes
has been insufficiently examined. Amphibians are globally endangered
and particularly sensitive to moisture conditions. For mating, most
amphibian species rely on calling behaviour, which is a key weather-
dependent trait. Using passive acoustics, we monitored the calling
behaviour of two widely distributed Neotropical frogs in 12
populations located at the humidity extremes but thermal mean of the
species distribution. Based on 2,554 hours of recordings over a
breeding season, we found that both the arboreal species Boana
raniceps and the aquatic species Pseudis paradoxa exhibited calling
behaviour at a wide range of relative humidity. Calling humidity was
significantly lower in conspecific populations subjected to drier
conditions, while calling temperature did not differ between
populations or species. Overall, no variation in climatic breadth was
observed between large and small choruses, and calling behaviour was
scarcely detected during the driest, hottest and coldest potential
periods of breeding. Our results showed that calling humidity of the
studied species varies according to the precipitation regime,
suggesting that widespread Neotropical anurans may have the capacity
to exhibit sexual displays in different climatic environments.
Regardless of the underlying mechanism (plasticity or local
adaptation), which should be determined by common garden experiments,
a wide and population-specific climatic breadth of calling behaviour
may assist species to deal with changing humidity conditions. To our
knowledge, this is the first study to explore the response capacity of
anurans to perform calling behaviour under contrasting precipitation
regimes.

LOCAL GEOMAGNETIC INDEX (LDI) FOR 1991 AT DIFFERENT LOCATIONS
- Guerrero Ortega, Antonio
- Cid Tortuero, Consuelo
- Saiz Villanueva, Elena
This local geomagnetic index indicates the perturbation of the geomagnetic field (horizontal component) for several locations. It is a measure of the external to the Earth irregular geomagnetic variations. It is obtained after removing a baseline and the daily regular variation from observed measurements.
