Abordagem ecofisiológica dos manguezais: uma revisão

Abstract

Mangrove has a high primary productivity that partly results from physiological mechanisms applied by plant species to environmental restrictions. This synthesis aims to assess the state of the art of ecophysiological studies on mangroves and identify gaps that allow increasing scientific knowledge on Brazilian mangroves and their potential contributions to climate changes. The worsening of environmental restrictions, such as increased salinity, longer flooding, and nutrient deficiency, induces a decrease of photosynthetic assimilation, resulting in a reduction in the development of species. The response of a given species to stress depends on its tolerance. We conclude that ecophysiological studies on mangrove vegetation are occasional, and their results differ between field and laboratory studies. In Brazil, this knowledge is still incipient, making it difficult to predict the behavior of species in face of climate change.
