b. Monthly precipitation along 1996. Arrows indicate sampling seasons.
The study was carried out in a very wet year after several ones with medium annual rainfall
(Figure 2a). Most of the rain in 1996 was recorded in January and autumn months, whereas
spring time presented a medium to low levels of rainfall. Consequently, samples from wet
(February) and dry (August) seasons were collected after a high and low precipitation period,
respectively (Figure b).
