Abstract

The Hato wetland is a freshwater biotope subject to the drought and rain regime, located in the
state of Nueva Esparta, Venezuela. Using the classical methodology for the study of aquatic systems, the temporal
space variation of the physicochemical and biological parameters of this ecosystem was evaluated. The results of the
Kruskal-Wallis Test showed statistically significant monthly differences for most of all parameters (P<0.05), except
for temperature and dissolved oxygen concentrations and apparent oxygen utilization at the spatial level. For the
depth strata the same behavior was discovered, with the exception of chlorophyll a. Through Spearman’s consequence
analysis, a positive association between temperature with dissolved oxygen and phosphate, as well as between silicate
and nitrite with phosphate is confirmed. The body of water presented oxygen concentrations and apparent oxygen use
that reflects photosynthesis processes associated with the presence of nutrients.
