Samosa and Kachuri from Mangrove Associate Species: An Innovative Utilization of Coastal Flora

The present study aims to investigate the phytoremediation potential of zinc (Zn), copper (Cu), and lead (Pb) by two dominant mangrove associate species, Suaeda maritima, and Salicornia brachiata, found in the high saline supralittoral zone of Indian Sundarbans in four stations of the Hooghly-Matla estuarine complex during the premonsoon season (May 2019). We found that concentrations of biologically available heavy metals (HMs) in the ambient soil and bioaccumulated HMs within the vegetative plant parts occurred as per the order: Sagar South > Bakkhali > Jharkhali > Bali Island. The order of biologically available and bioaccumulated HMs was Zn > Cu > Pb. Interestingly, the selected HMs display high organ-specificity for both species with the highest enrichment in roots, followed by stems and leaves. We propose that these halophytes could be used as agents of phytoremediation and their farming would be effective in the ecorestoration of this deltaic complex in context to conservative pollutants.

Abstract Floral biology, sexual system, breeding system, pollinators, fruiting and seed dispersal aspects of five mangrove associate species, namely, Clerodendrum inerme, Derris trifoliata, Suaeda maritima, S. monoica, and S. nudiflora were studied. All these species are hermaphroditic, self-compatible, and exhibit mixed breeding systems adapted for pollination by external agents. C. inerme and D. trifoliata are principally entomophilous, while Suaeda species are ambophilous. The study suggests that these plant species are important constituents of mangrove forests. C. inerme and D. trifoliata are useful in stabilizing the banks of back water creeks, while Suaeda species are useful to carpet the saline areas and desalinate the soils which are subsequently useful for agricultural activities.

Abstract Background Mangrove ecosystems have been the focus of global attention for their crucial role in sheltering coastal communities and retarding global climate change by sequestering ‘blue carbon’. China is relatively rich in mangrove diversity, with one-third of the ca. 70 true mangrove species and a number of mangrove associate species occurring naturally along the country’s coasts. Mangrove ecosystems, however, are widely threatened by intensifying human disturbances and rising sea levels. DNA barcoding technology may help protect mangrove ecosystems by providing rapid species identification. Results To investigate this potential, 898 plant specimens were collected from 33 major mangrove sites in China. Based on the morphologic diagnosis, the specimens were assigned to 72 species, including all 28 true mangrove species and all 12 mangrove associate species recorded in China. Three chloroplast DNA markers rbcL, trnH-psbA, matK, and one nuclear marker ITS2 were chosen to investigate the utility of using barcoding to identify these species. According to the criteria of barcoding gaps in genetic distance, sequence similarity, and phylogenetic monophyly, we propose that a single marker, ITS2, is sufficient to barcode the species of mangroves and their associates in China. Furthermore, rbcL or trnH-psbA can also be used to gather supplement confirming data. In using these barcodes, we revealed a very low level of genetic variation among geographic locations in the mangrove species, which is an alert to their vulnerability to climate and anthropogenic disturbances. Conclusion We suggest using ITS2 to barcode mangrove species and terrestrial coastal plants in South China. The DNA barcode sequences we obtained would be valuable in monitoring biodiversity and the restoration of ecosystems, which are essential for mangrove conservation.

Reliability of grass phytoliths for discriminating different deltaic sub-environments has been assessed on the modern surface sediments collected along the salinity gradient of the Sunderbans delta, India. It has been observed that grass phytolith assemblages can successfully distinguish different deltaic sub-environments especially the true mangrove zones from the mangrove associate and non-mangrove zones with minor overlaps, which further corroborated with the results of discriminant analysis (DA). Detrended correspondence analysis (DCA) and redundancy analysis (RDA) performed on the surface grass phytolith data show that salinity is the most crucial environmental parameter influencing grass phytolith distribution in the deltaic sub-environments. The potential of modern grass phytolith data in reconstructing past deltaic environmental changes has been further assessed on a late Quaternary fossil phytolith spectra from the Sunderbans spanning a sedimentary record for the last ~13.6 ka. A true mangrove environment with discernible tidal influence has been revealed between 13.6 and 3.9 ka. Absence of true mangrove–indicator grass phytoliths between ~3.9 and 2.2 ka further suggests disappearance of mangrove vegetation from this part of the Sunderbans which might have recolonized during ~2.2–0.8 ka. A mangrove associated or non-mangrove environment with little or no tidal influence came into existence in the study area since 0.8 ka onwards. A comparison with some earlier records suggests that the present grass phytolith-based palaeoenvironmental data shows conformity with the past dynamics in mangrove ecosystem in the east coast of India in respect to relative sea level changes.

It is difficult to associate species of the wood-boring moth in the genus Aenetus with their host plant, because larvae develop inside live trees. A new method is described for rearing larvae of Aenetus eximia, A. lewinii, A. blackburnii, A. ligniveren and A. scotti in cut stems of trees containing larval tunnels by feeding them apple pieces. Larvae that completed development were reared from 49 to 396 days after collection from the field. Aspects of larval feeding webs and adult emergence are described, and new host records are documented. The rearing method is shown to provide an effective means of accurately determining the species of Aenetus developing inside a given host plant. It was more convenient than obtaining pupae or emerging adults in the field, which is often not possible to do. The method should be useful for conducting surveys, particularly for species with wide distribution ranges. This method may also be effective for the study of other genera of callus feeding, stem boring Hepialidae, such as Archaeoaenetus, Endoclita, Phassus, Schausiana and Zeloptypia.
