“…The region's climate is classified as tropical with dry winter (Aw) according to the Köppen climate classification, with two well-defined seasons (dry and rainy) and average annual precipitation between 1,000 mm and 1,400 mm (Alvares et al, 2013). Rainy season is between October and April (Passos et al, 2017). The tidal cycle in the study area is semidiurnal and all sampling stations were low intertidal areas subject to approximately the same inundation regime as observed visually.…”

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.

This study aimed to estimate the fecundity of Ucides cordatus key species for the mangrove ecosystem. Fecundity in crustaceans is defined as the number of eggs produced during the spawning, generally evaluated by the relationship between cephalothorax width and number of eggs. Ovigerous female (n = 45) were collected in the estuary of the São Mateus River, Espírito Santo. Morphological variables (width, carapace length and wet weight) were measured and the ovigerous mass collected. Fertility was estimated by the gravimetric technique. The population, on average, had a cephalothorax width (WC) of 59.91 (± 9.10 mm), wet weight (WW) of 91.58 (± 36.06 g), wet weight of ovigerous mass (WOM) in 8.27 (± 2.98 g), and fecundity (F) in 170.080 ± (31.859 eggs/female). Fertility and the other variables showed positive correlations (p < 0.05), confirming that the increase in the number of eggs is closely related to the body increase. The variability of F as a function of LC was explained by the Potential model (R² = 0.45; p < 0.05), used to predict the number of eggs produced by females with different sizes, in a given population. Analyzes of the estimated reproductive potential contributes to public policies for managing the species, as it diagnoses environmental changes arising from impacts and pressures to capture. This study supports management actions and sustainable exploitation of this important ecological and economic resource, due to the scarcity of studies involving the reproductive attributes of the species in Brazil.

“…Thus, the use of the average as a project parameter may lead to its undersizing and, consequently, damage to the farmer (COAN et al, 2014). It is also possible to adopt 90% probability levels of probable monthly precipitation for crops with greater susceptibility to agronomic yield losses due to water stress (PASSOS et al, 2017).…”

The aim of this paper was to analyze the behavior of non-parametric statistical distributions on the prediction of probable monthly and total annual rainfall as well as to determine the monthly and annual probable rainfall with different levels of probability for Divinópolis, Minas Gerais State, Brazil. The analysis consisted in adjusting the theoretical probability distribution to a data series of 66 years of monthly and annual rainfall. The data were obtained from the Hidroweb service, controlled by the National Water Agency (ANA, in Portuguese). The frequency distributions of Gumbel for Maximus, Fréchet and Gamma were adjusted to the observed series, where the adherence of these models to the data were tested by the Kolmogorov-Smirnov and Chi-Squared test, both with 5% of probability. The model that best represented, in most cases, the frequency distributions of the series of total monthly precipitation was Gumbel for Maximus, while the Fréchet model had the worst result, not fitting to the data of the historical series for both tests performed in the study. The probable monthly maximum precipitation for Divinópolis is 527 mm, associated with a probability of 5% and for January, while the lowest one is 0.0042 mm, with probability of 95% in July.
