Keywords: Biogeochemistry, fractionation, mangroves, nutrient cycling, phosphorus
Abstract: Phosphorus (P) is an essential nutrient which plays a key role in global biogeochemical cycles. Costal ecosystems such as mangroves are an important sink which can trap significant quantities of P. The phosphorus as such deposited in sediments is not available to the organisms, but is converted to bioavailable forms as dissolved orthophosphate through a series of biogeochemical reactions. Several studies on phosphorus reservoirs, transport rates (fluxes) and residence times are reported from different ecosystems across the world. In the present article, an effort has been made to compile and review the scientific research carried out on phosphorus biogeochemistry in the mangroves of India.

Keywords: Environmental flow, flow duration curve, hydropower projects, river ecosystems.
Abstract: Increasing water withdrawals from many rivers of the world is leading to severe degradation in river ecosystems. Water is allocated for environmental needs so that a river can perform its natural functions. Environmental flows (EF) try to strike a balance between the use of water of a river for economic development, societal needs and delivering ecosystem services. This article describes a framework to assess environmental flows for a hydropower project in India in a situation where limited hydrological and very limited ecosystem data are available. It recommends that in such a situation, an acceptable EF regime can be arrived at by analysing hydrological data, supplemented by whatever ecosystem data are available and creating various scenarios of EFs. Benefits and impacts of different EF scenarios can then form the basis to determine an appropriate EF regime. Application of the framework is demonstrated in a case study in India. Adaptive management, where feedbacks are used to update and improve the decisions is helpful in such situations.

Keywords: Archaea, Bacteria, fungi, species concept, taxonomy and systematic
Abstract: Species is the basic unit of identification of a large diversity of organisms. The concept of species is old and has undergone several changes depending on the kind of organism(s).Earlier concepts were formulated considering mostly macro organisms (plants or animals).In 21st century the microbial species concept took shape which changed from morphological, ecological, biological and phylogenetic to more agreeable polyphasic species concept. Polyphasic species concept involves a combination of characters such as morphology, physiology, biochemical markers and sequencing of various regions of the DNA known as molecular markers. There are also specific criteria such as DNA-DNA hybridization for complex genera of Bacteria and Archaea, extrolite profiling for complex genera of fungi, etc. Although species concept and taxonomy of Bacteria are more systematic than fungi, taxonomy in two domains (bacteria, archaea) and fungi of eukarya domain is undergoing changes. The time is not far when genome sequencing will be considered as another criterion for delineating species. This article also discusses the role of various techniques (MALDI, FAME etc) in species identification. The concept of Candidatus species and species annotation for metagenomic studies is also discussed. We briefly describe the criteria used to delineate species various microbes and the need for different species concepts based on the kind of organism.

Abstract: Comparative study of the molecular dynamics of two xanthenes dye derivatives (Rhodamine-6G and Fluorescein-548) is reported using spectrally resolved three-pulse photon echo spectroscopy. An appreciable change in the coherence and population dynamics was observed between the two xanthenes derivatives due to the presence of different functional groups. Solution of Rhodamine-6G in methanol behaves in a more coherent fashion compared to that of Fluorescein-548 dye.

Abstract: It is believed that dogs were domesticated by man about 15,000 years ago to facilitate hunting, guarding and protection. During recent years, their services have extended to search operations, anti-terror tasks, detection of explosives and drugs, in forensics and to help in rescue operations. Today, according to an estimate, more than 700 million dogs inhabit sympatrically with human beings, worldwide. According to organizations working on the management and welfare of dogs, about 25 % of the dog population is owned/semi-owned, and the remaining 75 % is free-roaming, stray and feral. The frequent reproduction of dogs led to overabundant population that resulted into dog-human conflicts, such as dog bites, road traffic accidents, and inconvenience due to their escalated fights, blind chasing of one another on roads, barking and soiling. Overpopulation of dogs and its impact on wildlife (and humans too) have raised serious conservation concerns in many parts of the world.

Abstract: Platinum-group elements (PGE) are strongly siderophile elements, which provide valuable information on the petrogenesis of mantle-derived igneous rocks. The PGE abundances in the continental flood basalts (CFBs) are much lower compared to lithophile elements, usually at parts per billion (ppb) or even parts per trillion (ppt) levels. Nevertheless, they are potential markers of the magmatic process and source nature of the basalts, especially the Deccan Traps, has been fruitful and has brought forth wealth of information on the PGE concentration of Western and Eastern Deccan basalts (lava flows and dykes).

Keywords: Mechanism, self-pollination, Ajuga bracteosa Wallich ex Benth
Abstract: The movement of floral parts, including the pistil (style), stamen (filament, anther) and corolla has been observed in many angiosperms to affect successful pollination and mating. Various hypotheses have been proposed to explain the adaptive significance of floral movements. It has been reported that styles exhibit curvature movements either to promote outcrossing, or to affect selfing, or to achieve delayed selfing. In most of the cases the stigma, as the uppermost portion of pistil, is the seat of pollen reception. Here, we describe a mechanism of self-pollination in Ajuga bracteosa Wallich ex Benth, (Lamiaceae), in which the bisexual flower bends its stigmas in such a way so as to come in contact with dehisced anthers without the aid of any external agency to ensure self-pollination.

Abstract: Intact tropical forests cover 13.9 million sq.km worldwide, or 24 % of tropical land area. They are the most productive terrestrial ecosystems on Earth with high priorities for biodiversity conservation. These forests store a substantial amount of carbon in biomass and soil, and they also regulate the transfer of carbon into the atmosphere as carbon dioxide (CO2.Knowledge of the sign and magnitude of the stocks and flows of carbon and biomass within global forests is of importance in the context of climate change. Intact tropical forests in Amazonia and Africa have been increasing in biomass and thereby absorbing ~12 % of current anthropogenic CO2 emissions, but the continuity of this biomass carbon sink remains uncertain.
