Multiple markers pyrosequencing reveals highly diverse and host-specific fungal communities on the mangrove trees Avicennia marina and Rhizophora stylosa. | Fungi are important actors in ecological processes and trophic webs in mangroves. Although saprophytic fungi occurring in the intertidal part of mangrove have been well studied, little is known about the diversity and structure of the fungal communities in this ecosystem or about the importance of functional groups like pathogens and mutualists. Using tag-encoded 454 pyrosequencing of the ITS1, ITS2, nu-ssu-V5 and nu-ssu-V7 regions, we studied and compared the fungal communities found on the mar ... | 2011 | 22092266 |
seed predation by insects in tropical mangrove forests: extent and effects on seed viability and the growth of seedlings. | although insects are known to be important seed predators in most terrestrial forests, their role in marine tidal (mangrove) forests has not been examined. surveys at 12 sites in tropical australia showed that between 3.1 and 92.7 percent of the seeds or propagules of 12 mangrove tree species had been attacked by insects. seeds/propagules of six species (avicennia marina, bruguiera gymnorrhiza, b. parviflora, heritiera littoralis, xylocarpus australasicus and x. granatum) showed consistently hig ... | 1990 | 22160114 |

mangrove expansion and salt marsh decline at mangrove poleward limits. | mangroves are species of halophytic intertidal trees and shrubs derived from tropical genera and are likely delimited in latitudinal range by varying sensitivity to cold. there is now sufficient evidence that mangrove species have proliferated at or near their poleward limits on at least five continents over the past half century, at the expense of salt marsh. avicennia is the most cold-tolerant genus worldwide, and is the subject of most of the observed changes. avicennia germinans has extended ... | 2014 | 23907934 |
structural equation modelling reveals factors regulating surface sediment organic carbon content and co2 efflux in a subtropical mangrove. | mangroves are blue carbon ecosystems that sequester significant carbon but release co2, and to a lesser extent ch4, from the sediment through oxidation of organic carbon or from overlying water when flooded. previous studies, e.g. leopold et al. (2015), have investigated sediment organic carbon (soc) content and co2 flux separately, but could not provide a holistic perspective for both components of blue carbon. based on field data from a mangrove in southeast queensland, australia, we used a st ... | 2017 | 27836338 |
mangrove succession enriches the sediment microbial community in south china. | sediment microorganisms help create and maintain mangrove ecosystems. although the changes in vegetation during mangrove forest succession have been well studied, the changes in the sediment microbial community during mangrove succession are poorly understood. to investigate the changes in the sediment microbial community during succession of mangroves at zhanjiang, south china, we used phospholipid fatty acid (plfa) analysis and the following chronosequence from primary to climax community: unv ... | 2016 | 27265262 |
metal (pb, zn and cu) uptake and tolerance by mangroves in relation to root anatomy and lignification/suberization. | metal pollution has been widely reported in mangrove wetlands; however, the mechanisms involved in metal detoxification by mangroves are still poorly understood. this study aimed to investigate the possible function of root anatomy and lignification/suberization on metal uptake and tolerance in seedlings of six species of mangroves. the results revealed that the three rhizophoraceous species (bruguiera gymnorrhiza (l.) poir, kandelia obovata sheue, liu & yong and rhizophora stylosa griff) consis ... | 2014 | 24965807 |
modelling reveals endogenous osmotic adaptation of storage tissue water potential as an important driver determining different stem diameter variation patterns in the mangrove species avicennia marina and rhizophora stylosa. | stem diameter variations are mainly determined by the radial water transport between xylem and storage tissues. this radial transport results from the water potential difference between these tissues, which is influenced by both hydraulic and carbon related processes. measurements have shown that when subjected to the same environmental conditions, the co-occurring mangrove species avicennia marina and rhizophora stylosa unexpectedly show a totally different pattern in daily stem diameter variat ... | 2014 | 24534674 |
