Nonstructural carbohydrate (NSC) accumulation in submergence tolerant rice cultivars (cv) was studied in six Indica rice [Oryza sativa (L.)] cv under control and simulated submerged conditions. Tolerant cultivars accumulated greater contents of NSC compared to the susceptible cultivars. Starch and total NSC content showed significant positive association with survival percentage. On the other hand, elongation due to submergence was significantly a negative association with survival. The CO2 photosynthetic rate, chlorophyll content, maximum photochemical efficiency of PS II (Fv/Fm), and activities of Rubisco were not significantly different between tolerant and susceptible cv under control condition. The ADP glucose pyrophosphorylase (AGPPase) activity was significantly higher in the tolerant cv and was a positive association with starch/NSC, whereas Fructose 1,6-diphosphatase (FDPase) activity was significantly higher in susceptible cv compared to tolerant cv and was a negative association with starch/NSC. Greater activities of AGPPase along with lower activities of FDPase might facilitate greater accumulation of NSC in tolerant rice cultivars. © 2013 Taylor & Francis.

Medicinal plants possess unlimited and untapped wealth of chemical compounds with high drug potential which make these plants useful as sources of biomedicines. The rising demand for herbal medicines in the organized manufacturing sector has ruthlessly exploited the wild growing plant population those have bulk use. So for high rate multiplication of different medicinal plants, it is necessary to standardize the protocol for high regeneration. The efficiency of any regeneration is primarily depends on factors like type of explants used, composition of the medium and type of genotype. Here, we have developed a regeneration protocol of Desmodium gangeticum (L.) DC (Salparni, Fam- Fabaceae) a medicinal plant through axillary bud multiplication. Nodal explants from Desmodium gangeticum plants were cultured on Murashige and Skoog's basal medium with Kn or BA at different concentrations. 0.5 mg L-1 BA in the medium, showed shoot multiplication. Regenerated shoots measuring 3 cm or more were excised and planted on semi solid basal medium supplemented with varying concentrations of either IAA or IBA for induction of rooting. IBA treatment at 1.0 mg L-1 was the best eliciting 100% rooting response. The in vitro propagation protocol standardized can be highly useful in raising quality planting materials of Desmodium gangeticum for commercial plantation programmes and germplasm conservation. © 2012 Asian Network for Scientific Information.

Climate change induced sea level rise (SLR) added with anthropogenically altered environment leads to rapid land dynamics in terms of erosion and accretion; and alteration in species diversity and productivity, more pronouncedly in sensitive ecosystems such as river deltas. Here, we tried to analyze the historical records to understand the SLR with respect to hydrological conditions, sedimentation and morphological processes. We analyzed the land transformation of few islands in Indian Sunderbans using maps and satellite images in increasing order of temporal frequency between 1924 and 2008, which revealed that both the erosion and accretion processes go hand in hand. Increase of downstream salinity due obstruction in upstream has led to decrease in transparency of water causing decrease in phytoplankton and fish, density and diversity in the central sector of Indian Sunderbans. Analysis of the above ground biomass of three dominant mangrove species (Sonneratia apetala, Avicennia alba and Excoecaria agallocha) revealed better growth in the western sector compared to the central sector. The study reveals the cumulative effect of climate change and anthropogenic disturbance on the diversity and productivity in World's largest ecosystem; and advocates mangrove plantation and effective management of freshwater resources for conservation of the most vulnerable and sensitive ecosystem. © 2012 Springer Science+Business Media B.V.

Present paper consists the record of six species of mudskippers along with their morphometric analysis and spatial distribution from Bhitarkanika mangroves of Odisha, in the east coast of India. The six species of mudskippers are distributed under six genera Apocryptes (A. bato), Baleopthalmus (B. boddarti), Parapocryptes (P. serperaster), Periophthalmus (P. novemradiatus), Pseudapocryptes (Ps. elongatus) and Scartelaos (S. histophorus). The study was conducted from November 2010 to March 2013 in Bhitarkanika Wildlife sanctuary covering four survey sites representing degraded mangrove in downstream seaward side, the mangrove region and degraded mangrove in upstream tidal riverward side. While Baleopthalmus boddarti and Pseudapocryptes elongatus are found in all four habitats, Parapocryptes serperaster and Scartelaos histophorus are found both from seaward side and riverward side. Apocryptes bato are exclusively from upstream tidal riverward side and Periopthalmus novemradiatus are found exclusively from mangrove regions. P. serperaster were found to be the longest, A. bato were the heaviest and P. novemradiatus were the smallest as well as lightest. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

In this paper, we study the complex dynamics of a spatial nonlinear predator-prey system under harvesting. A modified Leslie–Gower model with Holling type IV functional response and nonlinear harvesting of prey is considered. We perform a detailed stability and Hopf bifurcation analysis of the spatial model system and determine the direction of Hopf bifurcation and stability of the bifurcating periodic solutions. Numerical simulations were performed to figure out how Turing patterns evolve under nonlinear harvesting. Simulation study leads to a few interesting sequences of pattern formation, which may be relevant in real world situations. © 2014, Springer Science+Business Media Dordrecht.
