Fig. 6From: Evaluating the potential impact of bird predation on the SW Atlantic fiddler crab Leptuca uruguayensisPopulation density changes in three different fiddler crab patches. Black dots and vertical lines show the mean and 95% confidence limits, respectively, for the population density of monitored patches at each sampling date. Horizontal Grey solid and dotted lines delimit the mean and 95% confidence limits for the trend across time of population density expected by the Monte Carlo modelBack to article page
