Although ecosystem services are increasingly recognized as benefits people obtain from nature, we still have a poor understanding of how they actually enhance multidimensional human well-being, and how well-being is affected by ecosystem change. We develop a concept of &amp;#8220;ecosystem service elasticity&amp;#8221; (ES elasticity) that describes the sensitivity of human well-being to changes in ecosystems. ES Elasticity is a result of complex social and ecological dynamics and is context dependent, individually variable, and likely to demonstrate nonlinear dynamics such as thresholds and hysteresis. We present a conceptual framework that unpacks the chain of causality from ecosystem stocks through flows, goods, value, and shares to contribute to the...

Bioindicators assess the mangroves ecological state according to the types of pressures but they differ with the ecosystem’s specificities. We investigated benthic meiofauna diversity and structure within the low human-impacted mangroves in French Guiana (South America) in response to sediment variables with various distances to the main city. Contaminant’s concentrations differed among the stations, but they remained below toxicity guidelines. Meiofauna structure (Foraminifera, Kinorhyncha, Nematoda) however varied accordingly. Nematode’s identification brought details on the sediment’s quality. The opportunistic genus Paraethmolaimus (Jensen, 1994) strongly correlated to the higher concentrations of Hg, Pb. Anoxic sediments were marked by organic...

Extreme marine environments cover more than 50% of the Earth’s surface and offer many opportunities for investigating the biological responses and adaptations of organisms to stressful life conditions. Extreme marine environments are sometimes associated with ephemeral and unstable ecosystems, but can host abundant, often endemic and well-adapted meiofaunal species. In this review, we present an integrated view of the biodiversity, ecology and physiological responses of marine meiofauna inhabiting several extreme marine environments (mangroves, submarine caves, Polar ecosystems, hypersaline areas, hypoxic/anoxic environments, hydrothermal vents, cold seeps, carcasses/sunken woods, deep-sea canyons, deep hypersaline anoxic basins [DHABs] and hadal zones)....

Revegetation of abandoned aquaculture regions should be a priority for any integrated coastal zone management (ICZM). This paper examines the potential of a matchless time series of 20 very high spatial resolution (VHSR) optical satellite images acquired for mapping trends in the evolution of mangrove forests from 2001 to 2015 in an estuary fragmented into aquaculture ponds. Evolution of mangrove extent was quantified through robust multitemporal analysis based on supervised image classification. Results indicated that mangroves are expanding inside and outside ponds and over pond dykes. However, the yearly expansion rate of vegetation cover greatly varied between replanted ponds. Ground truthing showed that only Rhizophora species had been planted,...

Organic matter in sediments in the mangrove areas and adjacent continental margins of Brazil .1. Amino acids and hexosamines
Provedor de dados: 5
Autores: Jennerjahn, Tc; Ittekkot, V.
The nature of sedimentary organic matter from mangroves and the continental margin of eastern Brazil (8 degrees-24 degrees S) has been investigated in order to obtain information on sources and diagenetic processes. The organic matter content of mangrove sediments is three to four times higher than the maximum content of continental margin sediments. Downslope distribution of organic carbon, nitrogen, amino acids and hexosamines shows an enrichment in water depths between 800 m and 1000 m. The distribution of individual amino acids and hexosamines is highly variable in sedimentary organic matter from mangroves and the continental margin, and the observed compositional differences are mainly due to diagenetic alteration. Organic matter is highly reactive in...

Mangroves and shoreline erosion in the Mekong River delta, Viet Nam
Provedor de dados: 5
Autores: Besset, Manon; Gratiot, Nicolas; Anthony, Edward J.; Bouchette, Frédéric; Goichot, Marc; Marchesiello, Patrick.
The question of the rampant erosion of the shorelines rimming the Mekong River delta has assumed increasing importance over the last few years. Among issues pertinent to this question is how it is related to mangroves. Using high-resolution satellite images, we compared the width of the mangrove belt fringing the shoreline in 2012 to shoreline change (advance, retreat) between 2003 and 2012 for 3687 cross-shore transects, spaced 100 m apart, and thus covering nearly 370 km of delta shoreline bearing mangroves. The results show no significant relationships. We infer from this that, once erosion sets in following sustained deficient mud supply to the coast, the rate of shoreline change is independent of the width of the mangrove belt. Numerous studies have...

Brachyuran crab community structure and associated sediment reworking activities in pioneer and young mangroves of French Guiana, South America
Provedor de dados: 5
Autores: Aschenbroich, Adelaide; Michaud, Emma; Stieglitz, Thomas; Fromard, Francois; Gardel, Antoine; Tavares, Marcos; Thouzeau, Gerard.
This study in French Guiana evaluates the changes of crab assemblages and their bioturbation activities between mangrove early stages (pioneer and young mangrove) and within stages by taking their spatial heterogeneity (tidal channels, flat areas, pools) into account. The results show differences in crab assemblage structure between and within the early stages of mangrove in relation to microhabitat and sediment characteristics. The sediment reworking rates are a function of the biomass or density of particular species (Ucides cordatus, Uca cumulanta) and burrower functional groups. Crab species or functional interaction mediate changes in sediment reworking rates suggesting the need to consider entire benthic communities rather than single species. This...

Mangrove‐Derived Organic and Inorganic Carbon Exchanges Between the Sinnamary Estuarine System (French Guiana, South America) and Atlantic Ocean
Provedor de dados: 5
Autores: Ray, Raghab; Thouzeau, Gerard; Walcker, Romain; Vantrepotte, Vincent; Gleixner, Gerd; Morvan, Sylvain; Devesa, Jeremy; Michaud, Emma.
There is growing evidence that a substantial fraction of the dissolved organic and inorganic carbon (DOC and DIC) and particulate organic carbon (POC) can be exported from mangroves to the ocean. Yet our understanding of C fluxes in mangrove forests is limited to only few regional studies that exclude the world's longest sediment dispersal system connected to the Amazon River. The present study aims at (1) examining tidal fluctuations of DOC, POC, and DIC; their isotopes; and optical properties such as chromophoric dissolved organic matter (CDOM) and (2) estimating their exchange fluxes between the mangroves and adjacent coastal water in the Sinnamary estuary, French Guiana. Time series observation highlighted that physical processes coupled to tides...

Application of spot data to a base-line ecological study of the mahakam delta mangroves (east kalimantan, indonesia)
Provedor de dados: 5
Autores: Dutrieux, Eric; Denis, Jacques; Populus, Jacques.
The objective of this study is to explain the spatial and temporal distribution of the vegetal communities of the Mahakam delta, chiefly on the basis of its physical and chemical characteristics. The delta is at present subjected to intense oil exploitation, and it is necessary to describe the situation on the site and its natural evolution in arder to be able to evaluate the damage that accidentai oil spillage could cause. The authors provide elements to define the sensitive zones whose protection should be a matter of priority. SPOT imagery was chosen as the tool allowing such an approach on a delta measuring 1 500 km2 SPOT satellite images of the Mahakam delta show that different plant communities succeed one another bath in time and in space.

Diversity and spatial heterogeneity of mangrove associated sponges of Curaçao and Aruba
Provedor de dados: 16
Autores: Hunting, E.R.; Soest, R.W.M. van; Geest, H.G. van der; Vos, A.; Debrot, A.O.
Sponges are major epibionts of mangrove roots in the Caribbean. Mangrove sponge communities in the Caribbean mainly consist of species that are typical to this habitat and community compositions often differ from those found on coral reefs nearby. Heterogeneity in species distributions between locations and within locations between roots is often reported. This study quantifies the diversity and abundance of mangrove associated sponges in the inner bays of Curaçao and Aruba and correlates variability of regional sponge diversity with environmental variables measured along the surveyed sites. Tannin concentrations vary between mangrove roots, and were correlated to sponge cover as a possible cause for habitat heterogeneity on a smaller scale. A total of 22...

Community Structure and Productivity of Mangroves at Nabq, Red Sea
Provedor de dados: 20
Autores: McCallum, J.N.; Paterson, L.; Greenwood, M.F.D.
Tree and pneumatophore height and density of Avicennia marina were measured along a point -intersection/band transect at Nabq, Red Sea, to establish possible zonation patterns amongst these mangrove characteristics. There was a significant increase in pneumatophore height and density landwards to seawards. Tree density decreased significantly down the transect. Graphical analysis showed an increase in tree height followed by a decrease at the seaward edge. Investigation of a theoretical increase in productivity (biomass) down the shore by leaf index calculation (leaf index = average leaf area x number of leaves per station) was inconclusive from data obtained.

GIS-based integration of interdisciplinary ecological data to detect land-cover changes in creek Mangroves at Gazi Bay, Kenya
Provedor de dados: 20
Autores: Koedam, N.; Dahdouh-Guebas, F.; De Wulf, R.; Tack, J.; Obade, P.T.
Historic environmental, faunal, floral and socioeconomic data of Gazi Bay in coastal Kenya were collated and integrated into a GIS environment and data of impacts due to various factors were then related to remotely sensed data. Rhizophora mucronata, a valuable mangrove species, was investigated. Very low values of basal area (7.7 m2/ha and 4.9 m2/ha) and complexity indices (1.86 and 1.12) at Makongeni and Kinondo 1, respectively, reflected intense human pressure in these areas. Areas that were easily accessible or close to human settlements appeared more vulnerable. Accrued information from a socioeconomic survey carried out over the same period corroborates the hypothesis that human influence was a major contributor to these changes. Historic aerial...

Utilization of mangrove wood products around Mida Creek (Kenya) amongst subsistence and commercial users
Provedor de dados: 20
Autores: Mathenge, C.; Dahdouh-Guebas, F.; Kairo, J.G.; Koedam, N.
Mida Creek (Kenya) comprises mangrove forests and other marine resources that are of economic, ecological and environmental importance to the local village communities.  In total 116 households (100 of which could be used for numerical analysis), which are estimated to correspond to a coverage of ca. 30 % of the total Mida Creek population, were interviewed to assess the human reliance on mangrove resources in Mida Creek.  The survey indicates that mangroves are a major resource of wood for house construction, fuelwood, charcoal and boat building.  Minor uses of mangrove products include pharmaceutical and medicinal applications, tanning material and furniture making.  Rhizophora mucronata, Ceriops tagal and Bruguiera gymnorrhiza are the major resources...

Como resultado de este suceso afloró el sustrato de esta punta, el cual esta formado de una granodiorita encrustada por corales arrecifales y cubierta por una arena cementada. En la fauna coralina están presentadas solamente especies recientes conocidas de la costa colombiana del Caribe. También se encontraron algunos moluscos y abundantes restos litificados de raíces de mangles.

The Assessment of Water Quality and Pollution in Tanzania
Provedor de dados: 20
Autores: Mohammed, S.M.
The coastal area of Tanzania (Fig. 1) encompasses a number of habitats that include coral reefs, mangroves, seagrass beds, sand banks, wetlands and beaches, among others. In addition to being essential linkages in the overall functioning of the coastal area, these coastal habitats support various resources both living and non-living. In addition, for generations the coastal area has provided life support to coastal communities where such activities as fisheries and related activities have played an important role in the social and economic development of local communities. In recent years, coastal tourism and mariculture have immerged as being potentially among most important economic activities nationally. The well being of these habitats and resources...

Autores: Kitheka, J.U.; Mwashote, B.M.
Gazi Bay (4.92°S, 39.50°E; Figure 1) is a shallow tropical coastal water system located on the southern coast of Kenya, approximately 50 km south of Mombasa. The total surface area of the bay including that covered by the mangrove forest is 15 km2. The mangrove forest covers a surface area of about 7 km2 (Kitheka 1996, 1997). Seagrass meadows and mangrove forest cover a surface area of about 12 km2. The bay is open to the Indian Ocean through a relatively wide (3,500 m) entrance, and is mostly shallow with mean depth at the entrance about 5 m. There are several narrow shallow cuts through the reef, which is mostly submerged except during spring tide. The bay is drained by two main rivers, the Kidogoweni River on the north-west part of the bay and the...

Les régions côtières de basse altitude sont fortement affectées par le changement climatique. Les mangroves jouent un rôle essentiel dans la protection des côtes : diminution de l’érosion, bouclier naturel contre les tempêtes. Peu d’initiatives abordent le développement de méthodes généralisables à un type d’écosystème ou même à plusieurs sites abritant des habitats similaires. L’examen de systèmes similaires peut conduire à une méthode généralisable dont la mise en oeuvre est susceptible d’orienter le développement de stratégies et de plans régionaux plus appropriés pour faire face aux impacts du CC, compte tenu de leur envergure.

Mangroves and estuaries
Provedor de dados: 20
Mangroves are forests of salt-tolerant trees and shrubs that grow in the shallow tidal waters of estuaries and coastal areas in tropical regions. They require slow currents, no frost and plenty of fine sediment in which to set their roots. Their muddy waters, rich in nutrients from decaying leaves and wood, are home to sponges, worms, crustaceans, molluscs and algae, and provide shelter for marine mammals, snakes and crocodiles. They act as fish nurseries and help feed life further out to sea. QueenslandÕs mangroves, for instance, do much to sustain the Great Barrier Reef, the worldÕs largest coral reef system. Mangroves are also strongly correlated with the presence of shoals of shrimp further offshore. Mangroves extend over 18 million hectares worldwide,...

Estimating The Returns To Mangrove Conversion: Sustainable Management Or Short Term Gain?
Provedor de dados: 20
Autores: Gammage, S.
The purpose of this project is to estimate the ‘total economic value’ of a mangrove ecosystem in part of the Gulf of Fonseca, El Salvador, and to develop a costbenefit framework to compare the sustainable management of the forest with alternative use scenarios. The current management strategy is compared to its sustainable counterpart, and to the partial conversion of the mangrove ecosystem to semi-intensive aquaculture and salt ponds. A variety of different valuation techniques are used to assess the contribution of different products and services of the mangrove ecosystem. Among these techniques, a ‘pseudo production function approach’ is used to calculate doseresponse estimates of the impact of mangrove loss on the productivity of marine and estuarine...

There is an international consensus, expressed in the Convention on Biological Diversity, World Summit on Sustainable Development, and Millennium Ecosystem Assessment, that biodiversity at all levels – genetic, species and ecosystem – have a critical role in sustaining livelihoods and human development. They underpin and make possible all forms of economic activity. Damage to components of biodiversity have economic consequences, the impacts of which fall most heavily on the poor. In few contexts is this as clear as in the case of mangrove ecosystems and their dependent human populations. Mangroves support livelihoods in providing habitat for food species, timber for dwellings, cooking and heat, and many other subsistence and commercial activities....

Autores: Ndongo, D.; Peter, S.; Priso, R.J.; Dibong, D.S.; François, B.
The Cameroon mangroves are exploited by local communities through fishing, hunting, and especially logging for fuel-wood and charcoal. The changing demographic patterns in the region have increased the need of citizens in the urban centres, which in turn, has accelerated the pressure on the neighbouring forests. The objective of these studies was to assess the impact of local communities on the mangroves’ development. Through an eight point semi-structured questionnaire, 120 mangrove loggers were interviewed in the local markets in Douala. The survey data show that 61% of respondents are permanent workers and do not envisage quitting this mode of employment. The surface area destroyed annually approximates 1000 ha. Species of the genus Rhizophora are...

The implications of wood exploitation for fish smoking on mangrove ecosystem conservation in the South West Province, Cameroon
Provedor de dados: 20
Autores: Mario, G.M.; Njisuh, Z. F.
In this study we investigated how the use of mangrove wood for fish smoking by local people in some localities of the South West (SW) Province of Cameroon may be in conflict with the conservation and sustainability of mangrove ecosystems. With the use of socio-economic surveys, from February to July 2006, we established that the amount of the annual fuel-wood harvest for five study sites was about 102,650 m3 (i.e., an amount equivalent to clearing about 205.3 ha of mangrove forests annually). It is estimated that approximately 62% of this total is used to smoke most of the fish (i.e., about 90.7% of the fish landings) across the five study sites. The quantities of wood seemed to vary proportionately with fish landings across sites, hence indicating a...

Within the framework of the CARICOMP(Caribbean Coastal Marine Productivity) monitoring program, a study of the Avicennia germinans mangrove formation of Chengue bay (Tayrona Natural Park, Colombia) was performed between June 1995 and July 1996, based on the evaluation of structural and functional characteristics at three monitoring plots (10 x 10 m). The structure of the studied formation is coincident with that of fringing forests of the Caribbean region in having small trees (dbh=11.3 cm, total height=6.3 m) and high densities (16.3 trunks/0.01 ha). During the monitored period there was a low mortality rate (0.7 trees/year) and there were significant increases of the circumferences at breast height (as well as of the variables derived from this measure)....

Les mangroves se retrouvent sur les bandes côtières protégées des régions tropicales et subtropicales. Une de leurs fonctions principales est de protéger les côtes des perturbations et de fournir des produits forestiers ligneux et non ligneux. Les mangroves sont également importantes pour la conservation de la diversité biologique et des moyens de subsistance ; elles représentent une zone privilégiée où les nombreuses espèces d’animaux (poissons, crevettes, crustacés) peuvent tirer leur nourriture et se reproduire. Malheureusement, lapression démographique qui a eu lieu dans plusieurs zones côtières a mené à leur conversion et, bien que l’information sur l’état et les tendances au niveau mondial reste rare, de nombreuses études citent la perte de mangroves...

The lower Krishna Basin trajectory: relationships between basin development and downstream environmental degradation
Provedor de dados: 31
Autores: Venot,   Jean-Philippe; Sharma,   Bharat R.; Rao,   Kamineni V.G.K.
Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated...

ABSTRACT Plankton samples obtained from the Ciénaga Grande de Santa Marta, an extensive estuarine system in northern Colombia, yielded adult male and female specimens of an undescribed halicyclopine cyclopid copepod of the genus Halicyclops. Cyclopid copepods are frequently found in freshwater and transitional habitats. Members of the subfamily Halicyclopinae are chiefly brackish water forms with a few freshwater species. The new species described herein is assignable to the group of species "F" of Halicyclops (sensu Pesce, 2018) with a 2333 exopodal spine formula. Currently, this group contains five species and one subspecies. Halicyclopsgutierrezi sp. n. can be distinguished from its known congeners by the absence of an anal operculum, the relative...

ABSTRACT Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under high salinity exhibited significantly lower performance (p&lt;0.05) in survival rates, cumulative shoot height, mean growth rates, mean total leaf area, and mean dry weight, compared to those under low and moderate salinity regimes. The low salinity treatment provided the best conditions for initial establishment and growth of the seedlings of all species until 15-20 weeks of age. However, the same...

Mangroves are classified as permanent preservation areas and regarded as natural nurseries. However, they have suffered several anthropogenic stresses, resulting in their decline. In the light of that, comes the importance of researching their environmental characteristics and revealing possible factors that have led to the degradation of this important ecosystem. The aim of this study was to evaluate the environmental quality of different areas in the mangroves of Ilha do Lameirão Ecological Station through microbiological analyzes of sediment and interstitial water along ten (10) sites, distributed in two areas with different conservation levels (Canal dos Escravos (CE) and Maria Ortiz (MO)) between 2010 and 2012.

Spectral characterization of mangrove leaves in the Brazilian Amazonian Coast: Turiaçu Bay, Maranhão State
Provedor de dados: 42
Autores: Rebelo-Mochel,Flávia; Ponzoni,Flávio J.
Mangrove communities are tropical systems which have fewer species than tropical forests, especially in Latin America and display a single architecture, usually lacking the various strata commonly found in other forest ecosystems. The identification of mangrove communities by orbital data is not a difficult task but the most interesting challenge is to identify themselves by the dominant species. The first step toward that floristic identification is the spectral characterization of detached leaves. Leaves from four species of mangrove trees were spectrally characterized considering the Directional Hemispherical Reflectance Factor (DHRF) determined through radiometric measurements using an integrating sphere LICOR 1800 attached to a spectroradiometer...

ABSTRACT This article describes the cartographic layer construction process of Colombian Caribbean coastal wetlands at a scale of 1:100,000 and the results obtained in terms of their quantification and typing. Two cartographic layers were constructed and subsequently joined, one of the permanent water bodies and another of temporary water bodies and associated coverages. The layers were generated by multitemporal analysis of 45 Landsat 8-OLI satellite images, based on the NDVI index, uncertainty models by superposition of cartographic attributes, and a flood frequency consultation model on ALOS PALSAR 1 images. As a result, 576,279 ha of coastal wetlands were delimited (1.9 % of total wetlands in Colombia), of which 20.4 % are within protected areas. The...

ABSTRACT The Guayas estuary in Ecuador is the largest estuarine ecosystem on the Pacific coast of South America. This estuary provides nursery and fisheries habitats, as well as filtering and detoxification services provided by suspension feeders, vegetation, and wetlands. We used oceanographic and meteorological observations to understand the hydrodynamic variability of two areas in the inner part of the estuary, Manglares de Churute and Estero Salado, from February 2016 to February 2017. Churute has less anthropogenic impacts than Estero Salado, which is currently uncoupled from river flow and highly influenced by Guayaquil, the second largest city in Ecuador, and adjacent shrimp pond effluents. The influences from the ocean and river on Churute include...

Absorption efficiency in post-larvae of the shrimp Litopenaeus vannamei fed a diet of marine yeast from mangrove mudflats
Provedor de dados: 50
Autores: Solorzano-Reyes,Fulvia; Velásquez-López,Patricio C.
ABSTRACT The present study investigated marine yeast as a food source in the Pacific white shrimp Litopenaeus vannamei. Yeast absorption efficiency was determined by measuring the proportion of organic matter assimilated by shrimp post-larvae (PLs). The yeast was isolated and propagated in the laboratory from a sediment sample obtained from a mangrove mudflat. Shrimp post-larvae at six stages, from PL-5-days-old to PL-35-days-old were fed exclusively with yeasts, at three concentrations (1.5 × 105, 3 × 105, 5 × 105cell/mL). The overall average of yeast absorption was around 65.85 ± 11.42 %. The two-way analysis of variance ANOVA (p &lt; 0.05) showed that the efficiency of yeast absorption was not affected by the concentrations of yeasts as a food source:...

Physiologic sexual maturity of the fiddler crab Uca rapax (Smith, 1870) (Crustacea, Ocypodidae) from two mangroves in Ubatuba, Brazil
Provedor de dados: 52
Autores: Castiglioni,Daniela da Silva; Negreiros-Fransozo,Maria Lucia.
The gonad development of Uca rapax was studied to achieve the size at onset of its sexual maturity. Crabs were sampled from April/2001 to March/2002 in the Itamambuca and Ubatumirim mangroves in Ubatuba, São Paulo, Brazil. The specimens were grouped in 10 size classes. Juveniles and adult crabs frequencies were assessed for each class. The size of carapace width in which 50% of males and females were considered mature was 14.8 and 12.1 mm (Itamambuca) and 13.6 and 11.4 mm (Ubatumirim), respectively for males and females. Males matured at higher sizes than females, probably due to a major investment in their somatic growth, while females spend their energy in the reproductive process, saving energy for eggs' production.

The mangrove's sediments from the coastal areas under human activities may contain significant contaminations by hydrocarbons, even when there are no visual evidences of it. The microorganisms are essential to these ecosystems, especially in the control of their chemical environment. Sediment samples were collected in two regions under different environment conditions (pristine and contaminated) of the Paranaguá Estuarine Complex (Paranaguá Bay and Laranjeiras Bay), Brazil. Aliphatic hydrocarbons were determined by the GC-FID to assess the status of contamination of the studied areas. The total DNA was extracted from these samples.

Autores: Ghizelini,Angela Michelato; Mendonça-Hagler,Leda Cristina Santana; Macrae,Andrew.
The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-review we introduce what mangroves are and why they are so important. We give a brief overview of the microbial diversity found in mangrove sediments and then focus on diversity studies from Brazilian mangroves. We highlight the breadth and depth of knowledge about mangrove microbial communities gained from studying Brazilian mangroves. We report on the exciting...

Bacterial diversity in relatively pristine and anthropogenically-influenced mangrove ecosystems (Goa, India)
Provedor de dados: 58
Autores: Fernandes,Sheryl Oliveira; Kirchman,David L.; Michotey,Valérie D.; Bonin,Patricia C.; LokaBharathi,P.A.
To appreciate differences in benthic bacterial community composition at the relatively pristine Tuvem and the anthropogenically-influenced Divar mangrove ecosystems in Goa, India, parallel tag sequencing of the V6 region of 16S rDNA was carried out. We hypothesize that availability of extraneously-derived anthropogenic substrates could act as a stimulatant but not a deterrent to promote higher bacterial diversity at Divar. Our observations revealed that the phylum Proteobacteria was dominant at both locations comprising 43-46% of total tags. The Tuvem ecosystem was characterized by an abundance of members belonging to the class Deltaproteobacteria (21%), ~ 2100 phylotypes and 1561 operational taxonomic units (OTUs) sharing &amp;gt; 97% similarity.

Salinity effects on leaf ion composition and salt secretion rate in Avicennia germinans (L.) L.
Provedor de dados: 61
Autores: Suárez,Nathalie; Medina,Ernesto.
The effect of salinity on leaf water relations, and rate and ionic composition of leaf secretion was investigated in plants of Avicennia germinans growing under controlled salinity conditions. Increases in salinity from 0 to 940 mol NaCl m-3 reduced the predawn water potential from -0.56 to -4.16 MPa and the solute potential from -2.27 to -4.48 MPa, whereas the pressure potential remained positive in all treatments. Compared to the control, at 940 mol NaCl m-3 Na+ and Cl- concentrations of leaf sap increased 19 and 7 times, respectively. With the addition of salt the main ions accumulated in leaves were Na+ and Cl- whereas plants grown without salt accumulated K+ in leaves at levels similar to those of Na+ with salt treatments. Secretion rates of Na+ and...

ABSTRACT: The extraction of sea salt depends on the occupation of large areas at the estuary banks, many of them inserted in Permanent Preservation Areas (PPAs). Thus, the objective was to evaluate the economic viability of Environmental Offsets (EO) as an alternative to the unoccupied PPAs in the saltworks. In order to do so, 27 solar saltworks installed in the region of the Brazilian White Coast were evaluated for the occupation of PPAs - measured using images from satellite, georeferenced, vectored with corresponding PPA bands generated - and estimated to EO (Impact Degree x Sum of the investments necessary to implement the project) and Economic Impact (Net Present Value, with long-term interest rate of 7%) of vacating PPAs.
