Impact of macroalgal blooms and wader predation on intertidal macroinvertebrate...
Lopes, Ricardo J.; Pardal, Miguel A.; Marques, João C.The effect of macroalgal blooms and predation by wading on benthic macroinvertebrates was examined in the Mondego estuary, Portugal, during spring 1997. Introduced macroalgal cover and exclusion of predators were used to examine changes in density of macroinvertebrates using univariate and multivariate analyses. There was no evidence of changes in numbers of macroinvertebrates due to predation. Macroalgae were,...
The impact of macroalgal blooms on the use of the intertidal area and feeding b...
Cabral, João Alexandre; Pardal, Miguel Â.; Lopes, Ricardo J.; Múrias, Tiago; Marques, João CarlosThe present paper examined the possible impact of macroalgal blooms, among other influential factors, on prey abundance and availability to waders, assessing the consequences for feeding behaviour and for the specific patterns of use of the intertidal areas by these birds when macroalgal mats become dense and contiguous covering large areas of the Mondego estuary (west Portugal). Three representative microhabit...
