Were propose to analyze the nest distribution of<br />Hypsiboas faber, in insular environment, as well as evaluate the structural and ecological aspects.<br />Were calculated the nest area correlating to the number of eggs, adjusting the variables to the<br />univariate straight-line equation, being the model tested through χ2. The density of nest distribution<br />was also evaluated, besides the abiotic data, such as dissolved oxygen, pH and nitrite. It was<br />observed the fidelity to the reproductive area during three years consecutives until the complete<br />destruction of the place to real state use. The species had used an area of 11.28 m2, of which the<br />center was occupied by a permanent puddle of 4 m2 in the outer dune. In the first sample period, it<br />was found 23 nests, in the following period 15 and in the last period just 9 nests. Beyond the number<br />of nests, were also observed the reduction of the area of the built nest from 0.30 m2 to 0.18 m2, being<br />this decline probably related to the human occupation, culminating with the complete elimination<br />of the reproductive area.
