“…Additionally, aguajales store a significant amount of carbon within their waterlogged soils and thick layers of organic matter largely composed of fallen palm fronds and inflorescences. Researchers working in the Orinoco River Basin found that aguajales store up to 95.91 kg/m 2 of carbon, underscoring the importance of these areas for carbon storage (Vegas-Vilarrubia et al, 2010).…”

Aim Potassium (K) is the second most abundant nutrient in plant photosynthetic tissues after nitrogen (N). Thousands of physiological and metabolic studies in recent decades have established the fundamental role of K in plant function, especially in water-use efficiency and economy, and yet macroecological studies have mostly overlooked this nutrient. MethodsWe have reviewed available studies on the content, stoichiometry and roles of K in the soil-plant system and in terrestrial ecosystems. We have also reviewed the impacts of global change drivers on K content, stoichiometry and roles. ConclusionsThe current literature indicates that K, at a global level, is as limiting as N and phosphorus (P) for plant productivity in terrestrial ecosystems. Some degree of K limitation has been seen in up to 70% of all studied terrestrial ecosystems. However, in some areas atmospheric K deposition from human activities is greater than that from natural sources. We are far from understanding the K fluxes between the atmosphere and land, and the role of anthropogenic activities in these fluxes. The increasing aridity expected in wide areas of the world makes K more critical through its role in water-use efficiency. N deposition exerts a strong impact on the ecosystem K cycle, decreasing K availability and increasing K limitation. Plant invasive success is enhanced by higher soil K availability, especially in environments without strong abiotic stresses. The impacts of other drivers of global change, such as increasing atmospheric CO2 or changes in land use, remain to be elucidated. Current models of the responses of ecosystems and carbon storage to projected global climatic and atmospheric changes are now starting to consider N and P, but they should also consider K, mostly in arid and semi-arid ecosystems.

“…Our total sediment N stocks are also comparable with other tropical mangrove forests (Fujimoto et al, 1999;Ramos e Silva et al, 2007), yet higher than temperate K. obovata sediment in Japan (Khan et al, 2007; Table 4). We speculate that the comparable sediment N stocks yet lower sediment C stocks in our study may be due to a higher proportion of N input originating from external sources (Bouillon et al, 2003), in comparison to peat based organic material (Fujimoto et al, 1999; Chmura et al, 2003;Vegas-Vilarrúbia et al, 2010;Donato et al, 2011).…”

“…Lower C stocks in temperate mangrove forest are predominantly a result of lower mangrove biomass (as described above), as well as lower sediment C stocks. In tropical studies the mangrove forest is typically growing in peat based sediments (Fujimoto et al, 1999;Chmura et al, 2003;Vegas-Vilarrúbia et al, 2010;Donato et al, 2011) while temperate mangrove forests are typically growing in mineral sediments (Howe et al, 2009;Saintilan et al, 2013).…”

Mangroves play an important role in the storage of carbon (C) and nitrogen (N) within estuarine systems, yet are being lost at an alarming rate throughout the tropics. In contrast, temperate mangroves have increased in area at many locations in recent decades. Field surveys, sediment sampling, allometry, and C and N analysis were used to determine total C and N stocks in five temperate Avicennia marina subsp. australasica forests in New Zealand. This is the first study developing allometric functions to estimate root biomass C and N stocks for A. marina. A. marina forests stored 117.1 ± 16.8 t C ha −1 and 15.4 ± 1.0 t N ha −1 in above and below-ground biomass and sediment to 100 cm depth. Below-ground biomass and sediment C and N stocks contributed 88 ± 3 and 99 ± 0.4% to total C and N stocks, respectively, emphasizing the importance of below-ground biomass and sediment in mangrove ecosystems. The results of this study can be used to inform management decisions for estuarine and coastal ecosystems, currently undergoing rapid changes in mangrove area.
