Weather affects crocodilians biology, such as
reproduction. Studies that could provide future information about nesting are
extremely important for management programs based on nests harvesting. In this work, we analyzed the relationship between
number of caiman nests collected and rainfall in Santa Fe
province (Argentina)
on six reproductive seasons with the aim of predicting future number of nests. First,
we worked within a local scale; analysing number of nests in a certain area and
rainfall for a nearby place. We then searched for a relationship in a regional
scale. We found no relationship when looking at local scale, however, when we examined
the regional scale, number of nests and clutch size were related to precipitation.
Precipitation during September had a positive effect on clutch size. In
addition, number of nests was affected by rainfalls during reproductive seasons
