“…In general, mangrove plants grow optimally between the 5–20 ppt salinity range, while the majority of plants can survive under a salinity level of 35 ppt ( Patel et al., 2010 ; Wang et al., 2011 ; Kodikara et al., 2017 ). Excessive water salinity can cause stunted growth ( Parida et al., 2004 ), reduced biomass ( Ball, 2002 ; Hoppe-Speer et al., 2011 ), impaired photosynthesis ( Naidoo et al., 2002 ; Parida et al., 2004 ), peroxidized cell membrane lipids ( Silva et al., 2023 ), unbalanced reactive oxygen species generation ( Barnuevo and Asaeda, 2018 ), and interferes with water and nutrition uptake by the root system, resulting in very low survival rates ( Ball, 2002 ; Kodikara et al., 2017 ; Cao et al., 2023 ). There are significant interspecific differences in salt tolerance of mangroves, which regulate the response and competitive ability of mangrove species to salinity gradients ( Costa et al., 2015 ; Dangremond et al., 2015 ) and thus influence species distribution and flora composition ( Bunt et al., 1982 ; Ball and Pidsley 1995 ; Torres-Fernández del Campo et al., 2018 ).…”

“…This species, among other mangrove species, has some particularities as greater longevity in the understory (Kock, 1997;Lima et al, 2018), reproductive characteristics (e.g. viviparity) (Tomlinson, 1986;Vannucci, 2001), unique life story strategies and recruitment (Kibler et al, 2022), physiological mechanisms under fluctuating salinity conditions, high carbon stocking, among others (Pascoalini et al, 2022;Silva et al, 2023), and is susceptible to climate change (Agraz-Hernández et al, 2015;Irizarry and Andreu, 2023) that became it an interesting research subject.…”

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.
