Mangroves of the Warm Temperate Southwestern Atlantic is a regional ecosystem subgroup (level 4 unit IUCN Global Ecosystem Typology). It includes marine ecoregions Rio Grande and Southeastern Brazil. The mapped extent mangroves in 2020 was 709.5 km2, representing 0.5% global mangrove area. biota characterized by three species true mangroves, Rhizophora mangle, Laguncularia racemosa Avicennia schaueriana. are associated with estuaries, coastal lagoons bays, barrier islands. This province...
Abstract Of Brazil’s 7408 km of coastline 6786 contain mangrove forests, covering some 25,000 km2. Only one coastal state, Rio Grande do Sul, lacks coverage. Mangroves occur from the border with French Guiana, just above Equator (04°30′N) to well beyond Tropic Capricorn, reaching 28°30′S, near Laguna (Santa Catarina State). Because term may be applied various levels observation, specifying proper spacio-temporal scale is important describe system behavior. In this paper we a nested hierarchy...
Although mangroves are recognized by high capacity of carbon storage and sequestration, few studies have been dedicated to determine the monetary value this ecosystem service. Accordingly, aim study is assign values service in a protected area (Southeastern Brazil). This economic valuation was performed considering preexisting estimates sequestration aboveground biomass these forests average transaction credits. The mean varied according physiographic type from 19.00 ± 10.00 US$ ha−1 yr−1...
Abstract. Hypersaline tidal flats (HTFs) are coastal ecosystems with freshwater deficits often occurring in arid or semi-arid regions near mangrove supratidal zones no major fluvial contributions. Here, we estimate that organic carbon (OC), total nitrogen (TN) and phosphorus (TP) were buried at rates averaging 21 (±6), 1.7 (±0.3) 1.4 gm-2yr-1, respectively, during the previous century three contrasting HTF systems, one Brazil (eutrophic) two Australia (oligotrophic). Although these lower...
Remote sensing techniques offer useful tools for estimating forest biomass to large extent, thereby contributing the monitoring of land use and landcover dynamics effectiveness environmental policies. The main goal this study was investigate potential discrete return light detection ranging (lidar) data produce accurate aboveground (AGB) maps mangrove forests. AGB estimated in 34 small plots scatted over a 50 km2 Rio de Janeiro, Brazil. Plot computed using either species-specific or...
A Lagoa da Tijuca, localizada ao sul cidade do Rio de Janeiro, possui estreita faixa manguezal distribuída forma descontínua longo suas margens. Os bosques mangue apresentam grande variabilidade estrutural. Nos monoespecíficos Laguncularia racemosa, com dap médio entre 3,4 e 7,7 cm altura média 4,5 m, há predomínio indivíduos menos 10,0 diâmetro. demais pontos, observamos mistos, mais desenvolvidos, dominados ora por Rhizophora mangle (dap 7,8 16,7 cm; 6,8 16,1 m), Avicennia schaueriana 7,1...
Abstract In this study, forest structure variability of a mangrove associated to salt flat in Sepetiba Bay (SE-Brazil) was assessed. Forest and interstitial water salinity were measured 32 plots established along three transects ranging from the margin estuary transition with flat. Structural development shown be highly variable, mean height 0.54 m 7.96 m, diameter 1.58 cm 9.46 trunk density 2,733 live trunks.ha-1 106,667 trunks.ha-1. responded gradient increasing towards flat, decreasing...
Structural and functional characteristics of mangrove forests are primarily governed by the interaction environmental characteristics, that act in global, regional or local scales. However, areas submitted to strong influence human activities, disturbance should be considered seriously. In this way, structural mangroves Guanabara bay were studied during three years (2000-2002). The presented a high diversity, reflecting action disturbances, determine different degradation levels regeneration...
Studies on belowground roots biomass have increasingly reported the importance of contribution this compartment in carbon stock maintenance mangrove forests. To date, there are no estimates Brazilian forests, although country has second largest area mangroves worldwide. For study, trenches dug fringing forests Guaratiba State Biological Reserve (Rio de Janeiro, Brazil) were used to evaluate different classes and vertical stratification stock. The total average these was 104.41 ± 20.73...
The southernmost presence of Rhizophora mangle in the western Atlantic coast occurs coastal wetlands between 27 and 28°S State Santa Catarina, Brazil. We selected mangrove communities at estuary River Tavares, Florianopolis, Sonho Beach, Palhosa, for measurement photosynthetic performance intrinsic water-use efficiency R. coexisting individuals Avicennia schaueriana Laguncularia racemosa, during spring season. used gas-exchange techniques isotopic signatures C N to estimate instantaneous...
This study evaluated the photosynthetic efficiency in Rhizophora mangle plants two mangrove forests, highest salinity (HS) area, and lower (LS) area. The CO2 assimilation rate (PN), stomatal conductance, leaf transpiration, intrinsic water-use efficiency, chlorophyll a fluorescence L-band, IP-phase, performance index were higher LS instantaneous initial fluorescence, maximum J-step HS growing area exhibited greater electron transfer between oxygen-evolving complex acceptor side of PSII....
The formation of annual growth rings has been confirmed for several mangrove species in the last decade, among which is Rhizophora mangle. However, record this was made a region with high hydric seasonality, widely recognized induction factor tropical species. In sense, present study aimed to verify occurrence R. mangle mangroves Guaratiba (Rio de Janeiro, Southeastern Brazil), low seasonality. For purpose, crossdating technique applied ten trees collected known age (seven years). are...
