POTENCY OF CONSORTIUM SYMBIONT MICROBE OF MANGROVE LITTER AS NATURAL PRESERVATIVE FOR TOFU

Symbiont bacteria from mangrove litter are known to have antimicrobial activity against Staphylococcus aureus. However, only a handful of research has been carried out on microbes as an innovative natural material for preserving food, especially tofu. This research used four species of mangrove litter symbiont microbe, which were cultured as a microbial consortium. The study aimed to determine the potential of consortium microbe as tofu preservatives. The tofu was soaked in the liquid culture of the consortium microbe as a treatment, while for the positive control, it was immersed in tofu using 37% formalin, and for the negative control, the tofu was not given any treatment. The organoleptic observations on the second day showed that the tofu with all treatment did not change in odor, color, and texture. On the other hand, tofu without treatment became more acidic in odor, with a yellowish color, and showed a softer texture. On the third day, tofu with bacterial microbe treatment had a slight change in odor, the color became yellowish, and the texture was slightly softened. Tofu with formalin treatment did not change in color, but became more solid and extruded formalin odor. Tofu with the consortium microbe immersion treatment had the least amount (6.795x103) of total microbe count, compared with the formalin treatment (9.766x103) and without treatment (9.766x103).

Economic Valuation of Mangrove Ecosystem in Coastal Area of Rokan Hilir Regency, Riau Province

Mangrove ecosystem is a very important resource for the continuity of community life in coastal areas. Mangrove ecosystem in the coastal area of downstream Rokan district has decreased mangrove area because it is used as a pond area to reduce the production of mangrove litter as an ecological function that can be a carrying capacity of coastal capture fisheries. However, the use of coastal areas as pond areas provides economic benefits for aquaculture. This study aims to calculate the economic value of the Rokan Hilir Coastal mangrove ecosystem. This research was conducted in March-April 2019 in the survey method. Analysis to calculate the total economic value of the mangrove ecosystem is NET=ML+MTL+MP. The results showed the total economic benefit value of Rokan Hilir mangrove forest reached IDR 98.697.950.594 / year was a direct benefit value of IDR 701,425,106 / year, indirect benefits were obtained at IDR 94,606,056,000 / year, and the optional benefits reached IDR 3,512,126,520 / year. Mangrove ecosystems are ecosystems that provide many benefits to the Rokan Hilir Coastal community, so this ecosystem is highly expected to be sustainable.

The level of mangrove litter production at Station 1 is 5.14 grams dry weight / m2, Station 2 is 2.80 grams dry weight / m2, and Station 3 is 6.67 grams dry weight / m2. The mangrove decomposition rate at station 1 was 63.33%, station 2 was 62.05% and station 3 was 67.73%.

Stable isotopes indicate ecosystem restructuring following climate‐driven mangrove dieback

AbstractExtreme climatic events can trigger sudden but often long‐lasting impacts in ecosystems by causing near to complete mortality of foundation (habitat‐forming) species. The magnitude and frequency of such events are expected to rise due to anthropogenic climate change, but the impacts that such events have on many foundation species and the ecosystems that they support remains poorly understood. In many cases, manipulative experimentation is extremely challenging and rarely feasible at a large scale. In late 2015 to early 2016, an extensive area of mangrove forest along ∼ 1000 km of coastline in the Gulf of Carpentaria, Australia, experienced severe dieback, an event associated with climatic extremes. To assess the effect this dieback event had on the mangrove ecosystem, we assessed benthic faunal assemblages and food web structure using stable carbon and nitrogen isotopes in a comparative experiment of impacted forest and adjacent unimpacted forest. Eighteen months after the dieback, the forest that suffered dieback contained significantly fewer crabs that rely on mangrove litter food source but more crabs that rely on microphytobenthos food source than the unimpacted forest. However, the infaunal biomass was largely unaffected by the mortality effect. This is most likely because microphytobenthos was largely unaffected and consequently, this buffered the food web responses. However, overall, the habitat value for mangrove ecosystem services most likely decreased due to lower physical habitat complexity following tree mortality. Longer‐term monitoring could lead to better understanding of biological effects of this extreme event and underlying biological mechanisms that drive changes and recovery.

Potentially toxic elements and biochemical components in surface sediments of NW Mexico: An assessment of contamination and trophic status

Abstract Concentrations of Potentially Toxic Elements (PTEs) were determined in sediments from Santa Maria La Reforma (SAMARE) coastal lagoon and Mocorito River, Mexico. Furthermore, biochemical composition of organic matter in sediments was analyzed to assess their trophic status. The PTEs concentrations followed the order Fe > Pb ∼ Zn > Cr ∼ Cu > Ni ∼ As ∼ Co > Cd. Except for As, PTEs showed correlation between them indicating a common source. As and Pb were above the threshold levels of toxic effect, but they did not exceed the levels of probable effect for biota. Metals were correlated with carbohydrates and As with lipids. Low protein/carbohydrate ratios suggest that decomposed detritus of nitrogen-rich algae as well as fresh mangrove litter can be present. These biochemical proxies suggest that meso-oligotrophic conditions prevail in SAMARE. Considering that fishing activities are practiced and that the northern portion of SAMARE was classified as a RAMSAR site, the information presented is useful to generate strategies for the management of this ecosystem.

Evaluating Litter Yield and Decomposition for Re-Vegetated Mangroves in a Subtropical Mudflat

Field monitoring and incubation experiments were conducted to evaluate the litter yield and examine the decomposition of the litter of three representative mangrove species frequently used for mangrove re-vegetation in a subtropical mudflat on the South China coast. The results show that the litter yield of the investigated mangrove species varied significantly from season to season. The annual litter production was in the following decreasing order: Heritiera littoralis > Thespesia populnea > Kandelia obovata. Initially, rapid decomposition of easily degradable components of the litter materials resulted in a marked weight loss of the mangrove litter. There was a good linear relationship between the length of field incubation time and the litter decomposition rate for both the branch and the leaf portion of the three investigated mangrove species. Approximately 50% or more of the added mangrove litter could be decomposed within one year and the decomposed litter could be incorporated into the underlying soils and consequently affect the soil carbon dynamics. An annual soil carbon increase from 2.37 to 4.64 g/kg in the top 5 cm of the soil was recorded for the investigated mangrove species.

The Molecular Identification of Sea Fungus Isolates from Mangrove Litter as Antimicrobials Potential

Marine microorganisms, one of which is sea fungus, have the potential to produce active metabolites which have pharmacological effects. This study aims to identify pure fungus isolates from mangrove litter and tested its antimicrobial activity on bacteria Escherichia coli, Staphylococcus aureus and fungus Candida albicans. In identification result of molecular using primary Internal Transcribed Spacer, Penicillium biourgeianum species were obtained in sequences DNA CTGGGTCAC…TAT. Sea fungus isolates later are fermented using a shaker at a speed of 150 rpm for 21 days and separated between the media and mycelium. The media was extracted liquid and the mycelium was macerated using ethyl acetate. Screening test of antimicrobial activity obtains the result showing antimicrobial activity against the tested microbes. Media culture and mycelium extracts which have antimicrobial activity are then determined by the MIC and MBC values. Most of the MIC test values are 256 μg/mL, which provide strong inhibitory. MBC value gained is 512 μg/mL showing a strong bactericidal. Study result shows that sea fungus isolates produce active metabolites that mostly have antimicrobial activity against Staphylococcus aureus ATCC29737, Escherichia coli ATCC10536, and Candida albicans ATCC10231.

Litter production and decomposition of mangrove in the Northern Coast of Aceh Besar district, Aceh province

Mangrove vegetation plays an important role and supplier of organic matter derived from litter fall and litter decomposition The purposes of this research was to obtain the productivity of mangrove vegetation by analyzing the litter fall, decomposition coefficient, and percentage of litter decomposed in the northern coast of Aceh Besar District. The research used purpossive sampling method to determine the 6 stations devided into 2 substations (landward and seaward). This research was conducted in July to September 2016. Each substation was put one of the litter trap. The litter trap method was used to know the mangrove litter production. Litter decomposition focused on R. mucronata leaves were studied by using litterbag technique. The litter bags were made of synthetic nylon which had size 20cm x 30cm and mesh size was 1 x 1.25 mm2. There were 3 types of mangrove found, litter production of Rhizophora mucronata as much as 79.21 g/m2/day, Avicennia marina as much as 0.70 g/m2/day and Sonneratia alba was 17.46 g/m2/day. Based on the substation influenced by tidal, mangrove litters found in the seaward higher than in the landward, the average litter fall was 52.05 g/m2/day and 43.32 g/m2/day. Result of mangrove decomposition showed that the percentage of decomposition for the 49th day in the seaward substation was 48.58% and the landward was 41.53%. Mangrove litter decomposition increased during the time at both substation. Decomposition rate of litter for Rhizopora mucronata species classified very quickly where the substation on the seaward was 0.012 (d−1) and landward was 0.010 (d−1). The half-time took in the leaf litter of mangroves for the landward was 69 days and seaward was 57 days, R. mucronata leaves litter decomposited in seaward substation was faster than landward.

Fish and macroinvertebrate fauna associated with floating or drifting surface water mangrove litter in a shallow coastal area in Trang, southern Thailand

Mangrove litter is continuously supplied to coastal water systems in and around Southeast Asian mangrove forests, often floating or drifting in surface layer water and likely providing ecological benefits for aquatic animals. As a first step toward clarification of possible roles of such litter in coastal ecosystems, associated fish/macroinvertebrate fauna in a shallow coastal area in Trang Province, Thailand, were examined by scoop-netting. During the study period, 398 individual fishes (35 species), 33 macrocrustaceans (8 species) and 30 squid (1 species) were collected. Larval/juvenile Zenarchopterus sp. 1 (cf. Z. dunckeri) were the most abundant fish (31.4% of total fishes), followed by Butis butis (16.3%) and Terapon jarbua (13.3%). A pygmy squid, Idiosepius sp., was the most abundant macroinvertebrate (47.6% of total). The majority of specimens collected were small-sized individuals. The mangrove litter, which adds a structured microhabitat to the non-structured surface water layer, probably functions (for small animals) in reducing energy costs for movement, including migration to other areas, as well as reducing predation risk and increasing food catchability, resulting in enhanced affinity of small animals for the litter.

Spatial and seasonal variation of mangrove litter production in Bitung, Indonesia

This study aimed to figure out a spatial and seasonal variation of litterfall production and its correlation with environmental parameters. The area was distinguished into three zones based on species domination, landward (Xylocarpus granatum); middle zone (Rhizophora apiculata) and seaward (Ceriops tagal). Four square, 50x50 cm (1 mm nylon mesh) litter traps were hung randomly in each zone, and the litters were collected monthly. Secondary climate data were compiled from the NOAA and BMKG, while soil and water contents were acquired from TIO-RCO investigation. The number of litter production on Kema was in the moderate category compared to several studies. Spatially, total litter production on landward (6.90±3.67 t.ha−1.y−1) and seaward (6.66±3.08 t.ha−1.y−1) were not significantly different, but they had a significant difference to the middle zone (8.93±4.85 t.ha− 1.y−1). Vegetative parts were highly dominant on litter composition. Total phosphate was highly correlated with spatial differences. Mangrove produced more litter during the dry season due to their higher metabolic adaptation to cope with the higher temperature and salinity. Even though there was no significant correlation between climate factors and total litter production. During season-transition periods, production of litterfall doubled than either dry/wet season followed by climatic parameter changes delivering physiological stresses.

Changes in dissolved organic matter composition and dynamics in a subtropical mangrove river driven by rainfall

Dissolved organic matter (DOM) plays an important role in sustaining ecosystem services of mangrove forests through well-described biogeochemical and ecological functions. This study was conducted in the Fukido River (Ishigaki Island, Japan) to better understand the seasonal and episodic changes in DOM concentration and composition in a subtropical mangrove system. Water samples were collected seasonally along a headwater–mangrove–sea transect on 10 occasions from September 2014 through June 2016. DOM was fractionated based on hydrophobicity into two fractions (hydrophobic and hydrophilic) and also analyzed by excitation-emission matrix spectroscopy combined with parallel factor analysis (PARAFAC). Although seasonal changes in DOM concentration and composition were not observed, both hydrophobic and hydrophilic DOM concentrations and levels of the identified three PARAFAC components clearly increased during a typhoon event. It is suggested that episodic increases in freshwater input due to a typhoon caused enhanced leaching of DOM from mangrove litter and dissolution of mangrove soil organic matter (SOM), which was otherwise retained in the mangrove soil by salinity-induced aggregation. The aggregation–dissolution properties of SOM are crucial in determining the magnitude of DOM outwelling and possibly SOM accumulation rate by enhancing advective DOM exchanges. Future studies are needed to evaluate the size of the carbon pool and outwelling of DOM after classifying mangrove forests based on the hydrological regime that influences biogeochemical conditions in the forests.

Impact of environmental factors on the dependency of litter biomass in carbon cycling of Hooghly estuary, India

Litterfall of the mangroves and its subsequent decomposition is an important mechanism in terms of productivity and nutrient cycle of that ecosystem. Present study emphasizes on the significance of litter biomass and role of environmental factors impacting this process. Mangrove litter undergoes degradation and decomposition and serves as the main source of carbon in different forms within the system, mangrove forests adjacent to the creeks at Sagar Island of the Hooghly–Matla estuarine ecosystem. This system receives a major load of carbon from adjacent mangrove forest in the form of litterfall throughout the year. Keeping in view the effect of environmental factors on litterfall and dynamics of carbon, machine learning method has been applied for this study. Different forms of carbon and environmental factors like temperature, salinity, pH, dissolved oxygen are estimated following standard procedure. Correlation, redundancy analysis and LASSO (Least Absolute Shrinkage and Selection Operator) regression are done in order to know the impact of environmental variables on carbon pool dynamics and effect of litterfall on the carbon pools in soil and water. The results reflect a strong correlation among the studied environmental factors and carbon pool dynamics. It has been revealed from the LASSO prediction results that each carbon pool is sensitive to a separate set of environmental factors.

New and cryptic species of intertidal mites (Acari, Oribatida) from the Western Caribbean – an integrative approach

ABSTRACTThe present study highlights the distribution, systematics, morphology, genetics, and ecology of two newly discovered intertidal oribatid mites from the Western Caribbean. The fortuyniid Litoribates floridae sp. nov. represents a cryptic species as it looks nearly identical to L. bonairensis. The two species can be distinguished only by subtle morphological and morphometric characteristics, whereas cytochrome oxidase subunit I gene sequences clearly separate the two taxa. The absence of morphological divergence in these disjunct species may have resulted from stabilizing selection due to the extreme intertidal environment. Litoribates floridae sp. nov. is presently known from the Florida Keys, primarily in mangrove leaf litter. The selenoribatid Thalassozetes balboa sp. nov. can be distinguished from all known congeners by a unique cuticular notogastral pattern, the presence of only two pairs of adanal setae, and two ventral teeth on each leg claw. It is morphologically most similar to T. barbara from the Eastern Caribbean. Thalassozetes balboa sp. nov. was found in Panama and Florida. This species usually occurs on rocky substrate and feeds on the intertidal alga Bostrychia.Litoribates floridaehttp://www.zoobank.org/urn:lsid:zoobank.org:act:A4B830FC-A03F-405D-9DE4-DE4C39DB6211Thalassozetes balboahttp://www.zoobank.org/urn:lsid:zoobank.org:act:EBF8C435-5C07-4B0E-8279-2101DC9E2CD4

Mangrove Leaf Litter Decomposition in a Seasonal Tropical Environment

Loria-Naranjo, M.; Sibaja-Cordero, J.A., and Cortes, J., 2019. Mangrove leaf litter decomposition in a seasonal tropical environment. Journal of Coastal Research, 35(1), 122–129. Coconut Creek (Florida), ISSN 0749-0208.Seasonal changes in rainfall might have an impact on the decomposition of mangrove leaf litter. This study analyzed the influence of weather conditions (season) on the decay rate, nitrogen, and phosphorus content as a decomposition indicator of leaf litter of Rhizophora racemosa. These measurements were taken at two sites in the Terraba–Sierpe National Wetland (TSNW) South Pacific, Coasta Rica, in 2013. The dry and wet season decay constants were similar and fast (k = 0.012 day–1). Decay constants were positively associated with salinity and water temperature (p <0.10). Moreover, season had an effect on the leaf litter nitrogen (high in dry season) and phosphorus content (high in rainy season). The effect of decomposition time on nitrogen and phosphorus content varies between sites. Leaf litter from R. racemosa acts as a substrate that releases nutrients to the ecosystem, contributing to carbon, nitrogen, and phosphorus budgets. The similar and fast decay constants among seasons is possibly because of the small difference in seasonal rainfall in TSNW, while seasonal variation in nitrogen and phosphorus is possibly a result of changes in microbial activity. This study highlights the need for an integral approach to research on nutrient cycling in mangrove forests because of its complex decay patterns.

Trophic relationships and basal resource utilisation in the Can Gio Mangrove Biosphere Reserve (Southern Vietnam)

Fatty acid biomarkers and dual stable isotopes (δ13C and δ15N) were used to identify the preferred food sources of consumers in a mangrove tidal creek and nearby unforested (mud bank) and forested areas located in the Can Gio Mangrove Biosphere Reserve (Southern Vietnam). We analysed 15 macro-invertebrates and 1 fish species representing primary consumers and their immediate predators in this area. Specific groups of fatty acids were used to trace the fate of various food sources (i.e., suspended particulate organic matter, mangrove litter and sedimentary organic matter). The δ13C and δ15N of consumers ranged from −26.9 to −18.8‰ and from 1.1 to 9.9‰, respectively. The trophic pathway based on mangrove litter, characteristic of mangrove ecosystems, is nutritionally sustaining various crab and snail species. In contrast, it appears that the most mobile species (fish and shrimps), living in the water column and possibly migrating with tides, are mostly feeding on suspended particulate organic matter, suggesting that this trophic pathway is of great importance for connectivity among tropical coastal ecosystems. Our study suggests that snails and crabs mainly act as mineralisers, processing high quantities of detrital material to meet their nutritional needs and thus releasing nutrients through the production of faeces, that are further mineralised by microorganisms, while locally grown phytoplankton reintegrates these compounds into its biomass and feeds migrating species. We highlight here a possible link between mangrove litter and coastal food webs.

Community structure of algae epiphytic in different leaf litter of mangroves

Mangrove is a plant that has the morphological and physiological adaptations to habitats which influenced by a tide. This plant can grow and develop in an environment of high salinity and its soil conditions are less stable and aerobic. Litter mangrove is the main source for the availability of detritus and is the largest component constituent of a food web in a mangrove ecosystem environment. Algae epiphytic microalgae is a group that lives attached to the plant, including the mangrove litter. The study aims to assess the abundance and diversity of epiphytic algae on different types of mangrove leaf litter. The observed mangroves leaf litter were Avicennia alba, Sonneratia sp. and Rhizophora sp. Epiphytic algae were brushed on mangrove leaf litter covering an area of 6.25 cm2 and diluted with distilled water. Samples were observed under a microscope with a magnification of 400 x. Water quality parameters were measured in situ and the organic ingredients, total N and P were analyzed. The results showed that epiphytic algae on each type of mangrove leaf litter were not different. Rhizophora sp is the most abundant and the richest species compared with other types of litter that are equal to 622 individuals / cm2 and 26 species of epiphytic algae. While the abundance of Avicennia alba and Sonneratia sp were 459 ind/cm2 and 321 ind /cm2, in the coastal mangrove areas of Morodemak was found 28 species of epiphytic algae. The common epiphytic algae species found in all types of mangrove litter were Cymbella sp., Coscinodiscus sp., and Synedra ulna. In general, the group of Bacillariophyta (diatoms) is the dominant species in some mangrove leaf.

Differential responses of litter decomposition to regional excessive nitrogen input and global warming between two mangrove species

Excessive nitrogen (N) input and warming affect litter decomposition and nutrient dynamics, especially in coastal areas. Understanding how mangrove litter decomposition responds to both excessive N input and warming is essential for estimating coastal carbon (C) and N cycling in the context of global change. In this study, we measured litter quality before and during the decomposition process of two mangrove species—Avicennia marina, a pioneer species, and Bruguiera gymnorrhiza, a late successional species—in a controlled experiment under treatments of N addition and warming. These two species dominate mangroves in southern China. Mass loss, C and N contents, and isotope values were measured over time as litter decomposed. N addition significantly increased the dry mass loss rates of B. gymnorrhiza litter by 52%, and warming significantly enhanced the dry mass loss of both A. marina and B. gymnorrhiza litter by 43% and 112%, respectively. N loss rate was not affected by the treatments but differed between the two mangrove species. There were no discernible changes in litter δ13C or δ15N throughout the decomposition process under N addition or warming, but the litter δ15N content was higher for A. marina than for B. gymnorrhiza, which indicated feedback between decomposers and litter chemistry. These results highlight that the litter decomposition rates of both mangrove species respond positively to regional N loading or global warming. The litter decomposition rate differed significantly between mangrove species because of differences in litter N content, C/N ratio and associated microorganisms.

A baseline study on trace element based sediment pollution and potential ecological risk of reef sediments of Musal, Manoli and Manoli putti Islands, Gulf of Mannar, India

The aim of the present study is to assess the baseline level of the trace element, sediment pollution and potential ecological risk of reef associated sediments of Musal, Manoli and Manoli putti Islands, Gulf of Mannar, India. The grain size distribution of the sediments is chiefly controlled by corals and broken shell debris. The distribution of lithoclastic fractions and element concentration are most probably derived from longshore sediment transport and fluvial process from nearby mainland. The enrichment of organic matter is chiefly controlled by mangrove litters and sea grasses. The concentration of lead in the marine sediments is subjected to sediment matrix, vicinity of the local pollutant sources and distance from the mainland coast. The ecological risk assessment clearly reveals that the sediments belong to the low risk category.

Potential Re-utilization of Composted Mangrove Litters for Pond Environment Quality Improvement

Production of mangrove litter from pruning and thinning activities is potential source of organic materials which could be re-utilized to improve pond environment quality and fertility. This research aimed to analyze the nutrient composition compost produced from mangrove litter and to describe the effect of compost application on pond quality. This research was conducted through two phases, including composting trial and application of compost on pond trial. Composting process was conducted for 45-60 days on mangrove litter achieved from pruning activities in the silvofishery pond using composting container, while application of compost in pond was conducted by pouring 2 kg of compost in 25 m2 pond. Production of compost included solid compost and liquid compost. Nutrient concentration of solid compost was ranged from 0.47-0.52% for N; 0.36-0.44% for P; and 5.45-6.39% for organic C, while liquid compost provided 0.62-0.69%; 0.24-0.32%; and 3.98-4.45% respectively for N, P and organic C. While C/N ratio was ranged from 11.60-12.78 and 5.77-7.18 respectively for solid and liquid compost. Solid compost quality resulted that N, P and C/N ration had fulfilled the standart criteria defined by Indonesia National Standart for compost. Observed impact of compost application on pond water quality were the improvement of water clarity and increasing abundance of klekap (lab-lab). This showed that mangrove litters could be converted into a more productive materials to enhance pond environment quality and productivity, decrease management cost and increase benefit. Scheduled fertilization with compost is suggested to be conducted to provide best benefit on silvofishery management.
