Abstract
Activity of Oophaga pumilio was
monitored on Isla Colón, Republic of Panama.
I quantitatively determined the number of
vocalizing male frogs and investigated
differences in hourly total activity and hourly
calling activity and the influence of weather
conditions such as temperature, humidity, light
intensity and rainfall on total activity and calling
activity during the day. 17
There was a statistically significant
difference between hourly time intervals for diel
calling activity in the dry season, and a positive
correlation between calling activity and light
intensity. Overall calling activity was high
between 10:30 am – 11:30 am, while calling
activity was at its lowest early in the morning and
late afternoon, and at its highest 9:30 am - 12:30
pm.
There was no significant difference
between total activity and temperature, total
activity and humidity, total activity and light
intensity, total activity and rainfall, calling
activity and temperature, calling activity and
humidity, calling activity and rainfall.
