In this paper, the accumulation of heavy metals of Nickel (Ni) and Vanadium (V) was measured in habitat sediments, mangrove roots and leaves (Avicennia marina). Besides, the transfer of Ni and V from the sediment to root and to the leaves in Nayband Bay and Qeshm Island were studied. The samples were gathered by Systematic-random Sampling using selective transects at 16 stations at the end of m...

A late-Holocene vegetation record is presented from the southwest coast of New Caledonia. Lac Saint Louis is a freshwater swamp at 3m a.s.l. adjacent to the River Coulee delta. Pollen analysis, charcoal analysis, radiocarbon dating and stratigraphic analyses have been used to reconstruct the vegetation and sedimentary history of the swamp. The sediment record commences at 6000 BP and reflects r...

Mangroves serve as either sinks or sources for inorganic and organic nutrients and can mitigate anthropogenic nutrient pollution, control the production in adjacent systems, and prevent eutrophication. To better understand the nutrient dynamics in a subtropical mangrove, we employed a three-way approach in the Nanliu River Estuary, southern China: Pore water profiles and sediment incubations re...

the inter-tidal mangrove environment of mengkabong lagoon is important as it supports the local fishing activities, nursery grounds for many fish and shellfish species, and as well as being central for ecotourism activities. the study showed that in general, the physicochemical parameters (ph, salinity and electrical conductivity), granulometric fractions, organic matter, base cations (na, k, c...

Mangrove crabs influence ecosystem processes through bioturbation and/or litter feeding. In Brazilian mangroves, the abundant and commercially important crab Ucides cordatus is the main faunal modifier of microtopography establishing up to 2 m deep burrows. They process more than 70% of the leaf litter and propagule production, thus promoting microbial degradation of detritus and benefiting mic...

Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...

The global knowledge of microbial diversity and function in Sundarbans ecosystem is still scarce, despite global advancement in understanding the microbial diversity. In the present study, we have analyzed the diversity and distribution of bacteria in the tropical mangrove sediments of Sundarbans using 16S rRNA gene amplicon sequencing. Metagenome is comprised of 1,53,926 sequences with 108.8 M...

Mangroves can capture and store organic carbon and their protection and therefore their restoration is a component of climate change mitigation. However, there are few empirical measurements of long-term carbon storage in mangroves or of how storage varies across environmental gradients. The context dependency of this process combined with geographically limited field sampling has made it diffi...

Positive plant–animal interactions are important in community ecology, but relatively little attention has been paid to their eVect on the production of mangroves, dominant halophytic trees in tropical coastal marshes. Here, the role of Wddler crab (Uca spp.) burrowing on the growth and production of the white mangrove, Laguncularia racemosa (<2 years old), was examined in a restored marsh in T...

Organic carbon in mangrove sediments originates from both local sources (mangroves, microphytobenthos) and tidal inputs (e.g. phytoplankton, seagrass-derived material). The relative inputs of these sources may vary strongly, both within and between different mangrove sites. We combined elemental (TOC/TN) and bulk delta13C analysis on sediment cores from various mangrove sites with delta13C data...
