“…In arid areas, an increase in temperature will increase the water vapor deficit and decrease the growth and survival of mangrove plants (Adame et al, 2021). Hypersaline conditions with high evaporation rates also lead to mangrove degradation, causing changes in species dominance and biodiversity (Alongi, 2021). At the ecosystem scale, rising temperatures are associated with the poleward expansion of mangroves at their subtropical and warm temperate latitudinal limits.…”

“…Similarly, at 800 ppm the growth of Avicennia marina and Rhizophora stylosa responded positively even when exposed to increasing tidal flooding to simulate sea‐level rise. However, gains were minimal under prolonged flooding conditions (Alongi, 2021; Jacotot et al, 2018).…”

The world's nations are committed to keeping global temperature rises to less than 2 C to avoid the worst impacts of climate change. Such a target is crucial for mangrove forests, because they are located primarily in tropical and subtropical regions that are expected to see large changes in climatic conditions; their intertidal location and sensitivity to changes in environmental conditions means that mangroves are expected to be on the front line of climate change impacts. We conceptualize what a 2 C world might look like for mangroves, and in particular the potential negative and positive responses of the mangrove ecosystem to anticipated changes in future atmospheric CO 2 concentrations, temperature, sea level, cyclone activity, storminess and changes in the frequency, and magnitude of climatic oscillations. We also assess the spatial distribution of such stressors, their relative contributions to mangrove ecosystem dynamics, and discuss the challenges in attributing mangrove ecosystem dynamics to climate change versus other global change stressors. Such knowledge can help future-proof conservation and restoration activities, improve the Intergovernmental Panel on Climate Change's confidence level ascribed to climate change impacts on mangrove forests, and highlight the key temperature thresholds beyond which the future of the world's mangroves is less certain.

“…This relationship is essential for understanding how the population dynamics of R. mangle will behave in the face of long-term variations in mean temperature and precipitation since changes in the patterns of these variables can modify the period of propagule release (Van der Stocken et al, 2017). Changes in temperature patterns, rainfall, and relative sea level caused by climate change can impact coastal ecosystems such as mangroves (Doney et al, 2012;Riascos et al, 2018;Alongi, 2021), since precipitation and temperature are important seasonal indicators for plant growth and development (Van der Stocken et al, 2017). Changes in seasonal rainfall patterns may lead to faster and deeper salt fluctuations in the top layer of soil, with the potential to affect the physiology of trees, saplings and seedlings in tropical rain forest (Stahl et al, 2013) interfering in carbon assimilation (in preparation) and long-term population dynamics.…”

Studies in the long-term recruitment and mortality of mangrove seedlings can help to understand mangrove demography and its relationship with climatic variables, environmental restoration and advances in the ecology of this ecosystem. A seven-year population dynamics study of seedling recruitment and mortality in cohorts of Rhizophora mangle L. was carried out to identify expansion processes and patterns of survival in the understory of mangrove forests on the Atlantic coast of Brazil. The present study aimed to evaluate the relationship between recruitment and mortality R. mangle seedlings at the population level, salinity, and climatic variables (precipitation, temperature and humidity). On an annual scale, seedling recruitment was positively correlated with mean temperature. Seedling density was negatively correlated with the number of recruits and positively with the number of deaths. The number of recruits was associated with dead seedlings, temperature and precipitation considering a population scale, without grouping the data. The seedling density in the stands increased with the number of dead seedlings. Our findings described the relationship between climate variability (durability and magnitude of the dry/rainy season) and the long-term population dynamics of R. mangle seedlings in a poorly studied region and from what moment, on a monthly and annual time scale, did this relationship become significant and changes occur. The findings of this study provide information on the population dynamics of the species that will help in understanding mangrove demography. These results have important implications for projections about the recruitment and survival of the species thinking about to long-term climate change that will modify current weather patterns and mangrove conservation efforts.
