Effects of soil flooding, sunlight and herbivory on seedlings of Annona glabra and Pachira aquatica in a tropical swamp
Wetland seedlings, in addition to dealing with the effects of flooding, must gain access to sunlight and avoid herbivore damage in order to establish. Understanding the effects of environmental factors on seedling growth and how plants modify their functional traits in response to them, is a challenge of wetland ecology. We evaluated the effects of different conditions of soil flooding (flooded and mesic), sunlight (closed and no canopy) and herbivory (presence and absence) on the survival, growth, and morphological traits of Annona glabra and Pachira aquatica seedlings, two dominant woody species of Neotropical swamps. We had eight experimental treatments with five replicates each. Our results showed that the survival of both species was high and was not affected by soil flooding, sunlight and herbivory. However, these factors affected plant growth rates. In general, the highest growth rates were observed in the treatment with high sunlight, mesicsoil and herbivore exclusion.
