Mangrove plants are cyclically exposed to variations in salinity. However, high salinity for long periods can significantly alter their metabolism. Here, we studied the effect of contrasting interstitial salinities (45 ppt vs. 70 ppt) on leaf morpho-physiological traits in adult Avicennia germinans L. trees in the dry and rainy seasons in Tampamach...

There is growing evidence that foliar water uptake (FWU) positively contributes to the water status of plants. However, the morpho-anatomical traits and the mechanisms responsible for variations in FWU of mangrove leaves are poorly understood. We evaluated the relationship between FWU and morpho-anatomical traits in eight mangrove species (Avicenni...

The oceans represent almost 70% of the surface of our planet, and they are in constant movement through waves, tides, and currents. These movements are formed differently: waves develop because of the action of the wind; tides because of the moon and the sun, and currents because of differences in water temperature and the rotation of the planet. O...

Mangroves are coastal ecosystems that encompass diverse gradients of latitude (30∘N–37∘ S), tidal height (<1m to >4 m), geomorphology (oceanic islands for river systems), sedimentary environment (peat to alluvial), climate (hot temperate to arid and humid tropics) and availability of nutrients (oligotrophic to eutrophic). Mangrove ecosystems are al...

Soil and water salinization is a major problem today. Many crop species do not tolerate this condition. The use of halophytes to remove salt from the soil and water is an emerging strategy. Environmental remediation using biodiversity has been widely used because it is a low cost and easy management technique, compared to chemical and physical amel...

Invasive species (weeds) contribute to great losses in crop productivity, and one of the strategies for controlling their distribution in the field involves the use of herbicides. However, the development of new formulations for the control of weeds is challenged by environmental issues, increases in the resistance of weeds to herbicides, and poor...

Mangroves have been subject to more metal contamination, including cadmium (Cd). This study evaluated if a relatively short Cd exposure may induce metabolic, morphological and ultrastructural cell disturbance in Avicennia schaueriana. Cd induced evident constraints to seedlings since there was reduction in leaf gas exchanges and the plants did not...

Mangrove sites are constantly under tidal regimes, where there is variation of dissolved oxygen and saline content in water. This study evaluated the effects of varying salinity in Avicennia schaueriana, an abundant species in the sea-mangrove-river interface. Seedlings of A. schaueriana were harvested at the riverbank and placed in different salin...
