“…TOM). To be a new tracer of mangrove development, the MOM contribution should be validated by mangrove pollen content, one of the most straightforward and effective proxies for tracing the history of mangrove development (Thornton and McManus, 1994;Gonneea et al, 2004;Versteegh et al, 2004;Wooller et al, 2007;Monacci et al, 2009;Ellison, 2008;Li et al, 2008;Xia et al, 2015).…”

“…Approximately 129,000 ha of mangrove forests disappeared between 1980 AD and 2000 AD in China, 97.6% of which was used for shrimp farming (Fan, 1995). Human activity has therefore significantly affected mangrove distributions in recent decades (Ellison, 1994), including SW China where mangroves are widely distributed (Xia et al, 2015). Therefore, it is important to understand the history of mangrove development and the impact of anthropogenic disturbance on mangrove ecosystems over the last 100 yr.…”

“…et al, 2004;Bouillon et al, 2008;Xia et al, 2015). However, contributions of OM from multiple sources with overlapping isotopic values can make it difficult to discern sources of OM in coastal systems (Cloern et al, 2002).…”

“…Thus, sediments from the floodplain should reasonably represent riverine input (Ottesen et al, 1989), with average values of -24.3 ± 0.7‰ for δ 13 C org and 12.6 ± 2.0 for C:N. The average δ 13 C org and C:N values for marine phytoplankton, collected from the northern South China Sea, were -16.1 ± 0.8‰ and 6.5 ± 0.7, representing the marine end member (Hou, 2009;Xue et al, 2009), respectively. The end member values of δ 13 C org and C:N for the three potential sources differ from each other (T-test, P < 0.05), and can be used to discriminate the buried OM sources in bulk sediments (Gonneea et al, 2004;Xia et al, 2015).…”

“…Recentemente, vários pesquisadores realizaram estudos considerando a relação das características físico-químicas do solo e a distribuição das espécies vegetais do ecossistema manguezal e constataram que, em curto prazo, a temperatura pode ser um fator chave nas mudanças na composição das comunidades de manguezais, pois está diretamente relacionada à produção de pólen e florescimento (Xia et al, 2015), e que a diminuição no aporte de água doce também RELAÇÃO DAS ESPÉCIES ARBÓREAS DO ECOSSISTEMA MANGUEZAL COM OS PADRÕES FÍSICO-QUÍMICOS DE SOLO: ESTUÁRIO DO RIO MACAÍPE, IPOJUCA -PE promove mudanças na zonação (Ranjan et al,2015).

RESUMOAs características físico-químicas do solo refletem processos globais e locais que influenciam na distribuição das formações vegetais. Nesse estudo, foi investigada a existência de padrões físico-químicos de solo associados às espécies arbóreas dos manguezais, por meio de análises físico-químicas do solo nas espécies Rizhophora mangle, Laguncularia racemosa, Avicennia schaueriana e Conocarpus erectus. Posteriormente, foi realizada a Análise dos Componentes Principais, utilizando a correlação de Pearson. Os componentes principais em R. mangle foram a capacidade de troca catiônica, soma das bases e argila; em L. racemosa, o hidrogênio, areia grossa e magnésio; em A. schaueriana, a capacidade de troca catiônica, fósforo e silte; em C. erectus, o potássio, cálcio e areia grossa. Os resultados sugerem padrões físico-químicos do solo nas espécies. Rizhophora mangle e A. schaueriana exibiram características físicas do solo semelhantes e atributos químicos distintos, do mesmo modo que L. racemosa e C. erectus. A disponibilidade de nutrientes e a capacidade de troca catiônica foram significativas para R. mangle e A. schaueriana, o pH, para L. racemosa e a composição granulométrica para C. erectus, sugerindo um padrão físico-químico do solo.Palavras-chave: Nutrição de Plantas; Rizhophora Mangle; Laguncularia Racemosa; Avicennia Schaueriana; Conocarpus Erectus.

Mangroves play an important role in carbon sequestration, but soil organic carbon (SOC) stocks differ between marine and estuarine mangroves, suggesting differing processes and drivers of SOC accumulation. Here, we compared undegraded and degraded marine and estuarine mangroves in a regional approach across the Indonesian archipelago for their SOC stocks and evaluated possible drivers imposed by nutrient limitations along the land‐to‐sea gradients. SOC stocks in natural marine mangroves (271–572 Mg ha−1 m−1) were much higher than under estuarine mangroves (100–315 Mg ha−1 m−1) with a further decrease caused by degradation to 80–132 Mg ha−1 m−1. Soils differed in C/N ratio (marine: 29–64; estuarine: 9–28), δ 15N (marine: −0.6 to 0.7‰; estuarine: 2.5 to 7.2‰), and plant‐available P (marine: 2.3–6.3 mg kg−1; estuarine: 0.16–1.8 mg kg−1). We found N and P supply of sea‐oriented mangroves primarily met by dominating symbiotic N2 fixation from air and P import from sea, while mangroves on the landward gradient increasingly covered their demand in N and P from allochthonous sources and SOM recycling. Pioneer plants favored by degradation further increased nutrient recycling from soil resulting in smaller SOC stocks in the topsoil. These processes explained the differences in SOC stocks along the land‐to‐sea gradient in each mangrove type as well as the SOC stock differences observed between estuarine and marine mangrove ecosystems. This first large‐scale evaluation of drivers of SOC stocks under mangroves thus suggests a continuum in mangrove functioning across scales and ecotypes and additionally provides viable proxies for carbon stock estimations in PES or REDD schemes.
