“…Using the ratio of mean biomass/ mean rate of biomass increment, Figure 2(d) shows that mangrove forests have the lowest turnover time (27 years) of aboveground biomass among the forest ecosystems, while tropical rain forests and tropical moist deciduous forests present renewal times of 43 and 36 years, respectively. The fast turnover rate of aboveground biomass corroborates the high resilience described for mangroves (Vogt et al 2012), which is, in the view of Alongi (2008), the result of an interaction among factors such as: high nutrient reserves in the substrate; high rates of nutrient flow and microbial decomposition; and the redundancy of key species, although disturbance regimes may also play a role (Duke 2002).…”

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.

“…Increased sampling of transitional areas may yield higher C stock estimates if mangrove seedlings can be found in association with other salt marsh species with higher C stocks. However, the presence of young mangroves is not evenly distributed for all salt marsh species, which may be influenced by altered hydrology due to mosquito control impoundments (Vogt et al 2012). Transitional areas are caused by propagule retention in salt marsh, which varies greatly by species due to structural complexity and stem density (Peterson and Bell 2012).…”

The climate change-induced expansion of mangroves into salt marshes could significantly alter the carbon (C) storage capacity of coastal wetlands, which have the highest average C storage per land area among unmanaged terrestrial ecosystems. Mangrove range expansion is occurring globally, but little is known about how these rapid climate-driven shifts may alter ecosystem C storage. Here, we quantify current C stocks in ecotonal wetlands across gradients of marsh-to mangrove-dominance, and use unique chronological maps of vegetation cover to estimate C stock changes from 2003 to 2010 in a 567-km 2 wildlife refuge in the mangrove-salt marsh ecotone. We report that over the 7-yr. period, total wetland C stocks increased 22 % due to mangrove encroachment into salt marshes. Newly established mangrove stands stored twice as much C on a per area basis as salt marsh primarily due to differences in aboveground biomass, and mangrove cover increased by 69 % during this short time interval. Wetland C storage within the wildlife refuge increased at a rate of 2.7 Mg C ha −1 yr. −1 , more than doubling the naturally high coastal wetland C sequestration rates. Mangrove expansion could account for a globally significant increase of terrestrial C storage, which may exert a considerable negative feedback on warming.

“…In mangrove forests, the physical damage and level of defoliation varied with distance from the eye walls of the hurricanes , Tomasko et al 2006. Mangrove stands with larger mangrove trees and lower densities sustained greater damage from hurricane winds (Vogt et al 2011). In addition, Proffitt et al (2006) found that, in the first year following the storms, mangrove reproduction was reduced by an order of magnitude.…”

“…We further hypothesized that damage and recovery would also vary by species and zone. Although some studies found that susceptibility to hurricane damage varies with species and size of mangrove (Baldwin et al 1995, Imbert et al 1996, McCoy et al 1996, Sherman et al 2001, Vogt et al 2011, others found similar levels of damage among mangrove species and among size classes within species (Odum et al 1982, Gresham et al 1991, Smith et al 1994, Sherman et al 2001. Because mangrove forests are often characterized by low floristic diversity, several studies have predicted that the recovery trajectory is relatively simple such that biological diversity, forest structure, ecosystem processes, and ecological functions will completely regain their former states following hurricane disturbance (Lugo et al 1976, Ogden 1992, Smith et al 1994.…”

Abstract. Mangroves are an ecological assemblage of trees and shrubs adapted to grow in intertidal environments along tropical, subtropical, and warm temperate coasts. Despite repeated demonstrations of their ecologic and economic value, multiple stressors including nutrient over-enrichment threaten these and other coastal wetlands globally. These ecosystems will be further stressed if tropical storm intensity and frequency increase in response to global climate changes. These stressors will likely interact, but the outcome of that interaction is uncertain. Here, we examined potential interaction between nutrient over-enrichment and the September 2004 hurricanes. Hurricanes Frances and Jeanne made landfall along Florida's Indian River Lagoon and caused extensive damage to a long-term fertilization experiment in a mangrove forest, which previously revealed that productivity was nitrogen (N) limited across the forest and, in particular, that N enrichment dramatically increased growth rates and aboveground biomass of stunted Avicennia germinans trees in the interior scrub zone. During the hurricanes, these trees experienced significant defoliation with three to four times greater reduction in leaf area index (LAI) than control trees. Over the long term, the þN scrub trees took four years to recover compared to two years for controls. In the adjacent fringe and transition zones, LAI was reduced by .70%, but with no differences based on zone or fertilization treatment. Despite continued delayed mortality for at least five years after the storms, LAI in the fringe and transition returned to pre-hurricane conditions in two years. Thus, nutrient over-enrichment of the coastal zone will increase the productivity of scrub mangroves, which dominate much of the mangrove landscape in Florida and the Caribbean; however, that benefit is offset by a decrease in their resistance and resilience to hurricane damage that has the potential to destabilize the system.
