Zooplankton selectivity and nutritional value of phytoplankton influences a rich variety of dynamics in a plankton population model.

Phys Rev E 2019 Jan;99(1-1):012406

Centre for Mathematical Biology and Ecology, Department of Mathematics, Jadavpur University, Kolkata 700032, India.

Mathematical modeling may be an excellent tool to analyze and explain complex biological phenomena. In this paper, we use a mathematical model to reveal various interesting dynamical features of phytoplankton-zooplankton interaction and attempt to explain the reason for contrasting dynamics shown by different laboratory and field experiments. Our study shows that the phytoplankton-zooplankton interaction in a pelagic system is very complex and the plankton dynamics, including the bloom phenomenon, strongly depends on the selective predation of zooplankton and the nutritional value of phytoplankton.

Hepatoprotective effects of rosmarinic acid: Insight into its mechanisms of action.

Biomed Pharmacother 2019 Feb 16;112:108600. Epub 2019 Feb 16.

Pharmacognosy Research Laboratories & Herbal Analysis Services, University of Greenwich, Chatham, Maritime Kent, ME4 4TB, UK.

Liver diseases such as hepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma are one of the major health challenges in the world and many conditions such as inadequate nutrition, viral infection, ethanol and drug abuse, xenobiotic exposure, and metabolic diseases have been implicated in the development and progression of liver diseases. Several factors including lipid peroxidation, production of reactive oxygen species (ROS), peroxynitrite formation, complement factors and proinflammatory mediators, such as cytokines and chemokines, are involved in hepatic diseases. Rosmarinic acid (RA) is a natural phenolic compound found mainly in the family Lamiaceae consisting of several medicinal plants, herbs and spices. Read More

Leaf biochemical adjustments in two Mediterranean resprouter species facing enhanced UV levels and reduced water availability before and after aerial biomass removal.

Plant Physiol Biochem 2019 Feb 5;137:130-143. Epub 2019 Feb 5.

Department of Environmental Sciences, Faculty of Sciences, University of Girona, Campus Montilivi, C/ Maria Aurèlia Capmany i Farnés 69, E-17003, Girona, Spain.

Effects of supplemented UV radiation and diminished water supply on the leaf concentrations of phenols and antioxidants of two Mediterranean resprouter species, Arbutus unedo and Quercus suber, were assessed before and after entire aerial biomass removal. Potted seedlings of both species were grown outdoors for 8 months with enhanced UV-A + UV-B, enhanced UV-A or ambient UV, in combination with two watering conditions (field capacity or watering reduction). After this period, all aerial biomass was removed and new shoots (resprouts) developed for a further 8 months under the two treatments. Read More

Toward optimisation of water use efficiency in dryland pastures using carbon isotope discrimination as a tool to select plant species mixtures.

Sci Total Environ 2019 Feb 4;665:698-708. Epub 2019 Feb 4.

School of Science and Environmental Research Institute, University of Waikato, Private Bag 3105, Hamilton, New Zealand.

Pastoral agriculture is important for supplying global demand for animal products but pasture productivity is often water limited. Increased plant diversity has been shown to increase water use efficiency (ω) and productivity under water limitation but the optimal mix of species varies spatially, dependent on climate, soil type, and plant water requirements. Consequently, a cost-effective method to screen for high ω plant species and mixes in situ at farm scale is needed. Read More

Certain new plant breeding techniques and their marketability in the context of EU GMO legislation - recent developments.

N Biotechnol 2019 Feb 16. Epub 2019 Feb 16.

Institute of Bioorganic Chemistry, Polish Academy of Sciences, Poznań, Poland. Electronic address:

The comparatively low adoption rate of GMO products in the European Union (EU) market seems to be connected with the strictness of authorization regulations and inefficiency of the authorization process itself. These problems will apply to any product deemed to be a GMO that could potentially be marketable in the EU. Since modern methods of plant breeding involving oligonucleotide-directed mutagenesis (ODMs) or site-directed nucleases (SDNs), including Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR), are becoming ever more popular, it is crucial to establish whether the products of such new breeding techniques (NBTs), in particular those which involve precise methods of mutagenesis, are exempted from the EU legislation on GMOs or not.

Harnessing the potential of integrated systematics for conservation of taxonomically complex, megadiverse plant groups.

Conserv Biol 2019 Feb 19. Epub 2019 Feb 19.

Royal Botanic Gardens, Kew, TW9 3AE, Richmond, Surrey, U.K.

The value of natural history collections for conservation science research is increasingly recognized, despite their well-documented limitations in terms of taxonomic, geographic, and temporal coverage. Specimen-based analyses are particularly important for tropical plant groups for which field observations are scarce and potentially unreliable due to high levels of diversity-amplifying identification challenges. Specimen databases curated by specialists are rich sources of authoritatively identified, georeferenced occurrence data, and such data are urgently needed for large genera. Read More
