“…In contrast, along the Southeastern granitic coast, mangroves are disappearing faster due to being squeezed within the narrow coastal plains by sea-level rise and increasing frequency of extreme weather events, and further maximized by strong human pressure. At the southern tip of this zone, mangrove forests may expand their latitudinal range as temperature and atmospheric CO 2 concentrations increase and the frequency of extreme cold events decrease, although as noted by Soares et al (2012) no evidence exists on this southward movement of the local mangroves. Along the Eastern Tertiary Coast, little, if any data exists on the response of mangroves to climate change in relation to their cover area and distribution.…”

“…However, it is expected that in response to global warming, these forest may expand southward, most by Laguncularia racemosa, presently limited by hash climatic conditions in winter. This extension southward may result from an increase in air and ocean surface temperatures, a reduction in the frequency of frost events, stronger influence of the Brazil Current and a weakening of the Falkland Current (Soares et al 2012)…”

Mangroves function as a natural coastline protection for erosion and inundation, providing important environmental services. Due to their geographical distribution at the continent-ocean interface, the mangrove habitat may suffer heavy impacts from global climate change, maximized by local human activities occurring in a given coastal region. This review analyzed the literature published over the last 25 years, on the documented response of mangroves to environmental change caused by global climate change, taking into consideration 104 case studies and predictive modeling, worldwide. Most studies appeared after the year 2000, as a response to the 1997 IPCC report. Although many reports showed that the world's mangrove area is decreasing due to direct anthropogenic pressure, several others, however, showed that in a variety of habitats mangroves are expanding as a response to global climate change. Worldwide, pole ward migration is extending the latitudinal limits of mangroves due to warmer winters and decreasing the frequency of extreme low temperatures, whereas in low-lying coastal plains, mangroves are migrating landward due to sea level rise, as demonstrated for the NE Brazilian coast. Taking into consideration climate change alone, mangroves in most areas will display a positive response. In some areas however, such as low-lying oceanic islands, such as in the Pacific and the Caribbean, and constrained coastlines, such as the SE Brazilian coast, mangroves will most probably not survive.

“…By restricting net productivity and affecting tree tissues (Steinke and Naidoo 1991, Kao et al 2004, Ellis et al 2006, Stuart et al 2007), low and freezing temperatures limit the structural development of forests, which are less developed and more likely to have shrub-like forms close to their latitudinal limits (Schaeffer-Novelli et al 1990, Bridgewater and Cresswell 1999, Stevens et al 2006, Soares et al 2012. Therefore, the importance of low temperature conditions in limiting the structural development of mangrove forests explains the best fit observed for the regressions between carbon stock and isothermality (R² = 0.23) minimum temperature of the coldest month (R² = 0.21) or mean temperature of the coldest quarter (R² = 0.20) compared with the annual mean temperature (R² = 0.11).…”

In order to contribute to understand the factors that control the provisioning of the ecosystem service of carbon storage by mangroves, data on carbon stock and sequestration in the aboveground biomass (AGB) from 73 articles were averaged and tested for the dependence on latitude, climatic parameters, physiographic types and age. Global means of carbon stock (78.0 ± 64.5 tC.ha -1 ) and sequestration (2.9 ± 2.2 tC.ha -1 .yr -1 ) showed that mangroves are among the forest ecosystems with greater capacity of carbon storage in AGB per area. On the global scale, carbon stock increases toward the equator (R²=0.22) and is dependent on 13 climatic parameters, which can be integrated in the following predictive equation: Carbon Stock in AGB = -16.342 + (8.341 x Isothermality) + (0.021 x Annual Precipitation) [R²=0.34; p < 0.05]. It was shown that almost 70% of carbon stock variability is explained by age. Carbon stock and sequestration also vary according to physiographic types, indicating the importance of hydroperiod and edaphic parameters to the local variability of carbon stock. By demonstrating the contribution of local and regional-global factors to carbon stock, this study provides information to the forecast of the effects of future climate changes and local anthropogenic forcings on this ecosystem service.

“…In this paper we report on the elemental composition of soils and plants from mangrove ecosystems located in the southernmost reaches of mangrove ecosystems along the South American Atlantic coast, in Santa Catarina State, Brazil (Schaeffer-Novelli et al, 1990;Soares et al, 2012). The objective was to determine the nutritional profiles of mangrove sediments and species to assess differences determined by local hydrological conditions and species physiology.…”

Heterogeneity of elemental composition and natural abundance of stables isotopes of C and N in soils and leaves of mangroves at their southernmost West Atlantic range

Mangrove communities were selected in the state of Santa Catarina, Brazil, near their southernmost limit of distribution, to study mineral nutrient relation in soils and plants. Communities included three true mangrove species, Rhizophora mangle, Laguncularia racemosa and Avicennia germinans, and two associated species, the fern Acrostichum danaeifolium, and the grass Spartina densiflora. The sites included communities in the lower Río Tavares near Florianopolis city, Sonho beach near Palhoça city, and the Santo Antonio lagoon. These sites included a full range of mangroves under humid climate where winter temperatures, instead of salinity, may be the main factor regulating their productive capacity and species composition. Soil salinity was determined by the concentration of soluble Na, and soil C and N were linearly correlated indicating their association in organic matter. Tavares site showed higher specific conductivity, and concentrations of Na and Mg in the soil layer below 40 cm depth, indicating larger influence of marine water. Isotopic signature of C increased with soil depth suggesting that microorganisms decomposing organic matter are releasing 13 C depleted CO 2 . Nitrogen isotopic signature decreased with soil depth, indicating enrichment in 15 N possibly as a result of denitrification in the upper soil layers. Mineral elements in leaf tissues showed A. schaueriana with higher concentrations of N, P, Na, K, Cu, Zn, and Na/Ca ratio. Spartina densiflora was characterized by the lowest N and K concentrations, and the highest concentrations of Al and Fe. Rhizophora mangle and L. racemosa had the highest Ca concentrations. Carbon isotopic signatures identified S. densiflora as a C4 plant, and A. schaueriana as the mangrove species occupying comparatively more water stressed microsites than the rest. Leaf nitrogen isotopic signatures were positive, in correspondence with the soil values. The results support the hypothesis that sites sampled were comparatively fertile, because sediment transport through fresh water run-off is predominant in humid coasts, and therefore plants were not limited by nutrient supply, nor particularly stressed by soil salinity.Keywords: mangroves, soils, leaves, nutrients, stable isotopes, southwestern Atlantic latitudinal limit.Heterogeneidade da composição elementar e abundância natural de isótopos estáveis de C e N no solo e folhas dos manguezais no extremo sul da sua distribuição na costa Atlântica ocidental
