Competition Is a Strong Driving Factor in Wetlands, Peaking during Drying Out Periods.

摘要: The aim of the study is to investigate relative importance plant-plant interactions with regard flooding and drought effect on perennial plant performances in wetlands. Flooding expected be major driver and, accordingly, hardly if ever taken into account. Focusing five widespread species, growth, survival competitive ability plants were monitored permanent plots spread along two elevation gradients. duration intensity found vary substantially ~ 0.5 meter range gradient. alternate over hydrological year pin-point surveys thus conducted course one year. data modeled taking account survival, recruitment growth throughout drying out periods. both directly impacted their effect, being much more general among species higher magnitude than flooding. competition was high for all particularly during period. It varied gradient tolerance shown by studied compared may related specific timing together efficient response traits. These results offer new insights filters operating pools. This suggests that period conditions even important species’ success pattern. applicability this result, obtained mild Atlantic climate fertile wetlands, remains studied.
