Rafflesia is a genus of flowering plants of the tropical rain forests that includes the largest flowers in the world ranging from 10 up to 100 cm in diameter-sizes unlike any other flower. The Rafflesia flower has been symbolic...

The contribution of flood disturbance, catchment geology and land use to the habitat template of periphyton in stream ecosystems

Cultural Transformation in the Geoscience Community AND Program Evaluation

Biggs BJF.

BJF Biggs - Freshwater biology, 1995 - Wiley Online Library

Periphyton chlorophyll a (chl a), ash‐free dry mass, taxonomic composition, and cellular and water‐column nutrients were analysed every 4 weeks for a year at sixteen stream sites in New Zealand. The hypothesis was investigated that broad‐scale differences in mean...

Multi-instrument assessment of phytoplankton abundance and cell sizes in mono-specific laboratory cultures and whole plankton community composition in …

The abundance and size distribution of plankton in the surface ocean are key metrics to understanding primary and export production, food web dynamics, and the optical properties of the water column. Here we quantified cell size and abundance of...

Tolerance of three grain legume species to transient waterlogging.

AoB PLANTS

Malik AI, Ailewe TI, Erskine W.
PMID: 25902834
AoB Plants. 2015 Apr 22;7. doi: 10.1093/aobpla/plv040.

Waterlogging reduces the yield of food crops. Tolerance to waterlogging could vary between and within species. This study aimed to quantify tolerance to soil waterlogging in two divergent genotypes of pea (Pisum sativum), two of lentil (Lens culinaris) and...

Effects of salt stress on the growth, ion content, stomatal behaviour and photosynthetic capacity of a salt-sensitive species, Phaseolus vulgaris L.

Planta

Seemann JR, Critchley C.
PMID: 24249556
Planta. 1985 May;164(2):151-62. doi: 10.1007/BF00396077.

Phaseolus vulgaris (cv. Hawkesbury Wonder) was grown over a range of NaCl concentrations (0-150 mM), and the effects on growth, ion relations and photosynthetic performance were examined. Dry and fresh weight decreased with increasing external NaCl concentration while the...

Quantum Coherent Excitation Energy Transfer by Carotenoids in Photosynthetic Light Harvesting.

The journal of physical chemistry letters

Roscioli JD, Ghosh S, LaFountain AM, Frank HA, Beck WF.
PMID: 28968122
J Phys Chem Lett. 2017 Oct 19;8(20):5141-5147. doi: 10.1021/acs.jpclett.7b01791. Epub 2017 Oct 06.

It remains an open question whether quantum coherence and molecular excitons created by delocalization of electronic excited states are essential features of the mechanisms that enable efficient light capture and excitation energy transfer to reaction centers in photosynthetic organisms....

Effects of High Temperature Frying of Spinach Leaves in Sunflower Oil on Carotenoids, Chlorophylls, and Tocopherol Composition.

Frontiers in chemistry

Zeb A, Nisar P.
PMID: 28382299
Front Chem. 2017 Mar 22;5:19. doi: 10.3389/fchem.2017.00019. eCollection 2017.

Spinach is one of the highly consumed vegetable, with significant nutritional, and beneficial properties. This study revealed for the first time, the effects of high temperature frying on the carotenoids, chlorophylls, and tocopherol contents of spinach leaves. Spinach leaves...

Visual Analysis for Detection and Quantification of Pseudomonas cichorii Disease Severity in Tomato Plants.

The plant pathology journal

Rajendran DK, Park E, Nagendran R, Hung NB, Cho BK, Kim KH, Lee YH.
PMID: 27493605
Plant Pathol J. 2016 Aug;32(4):300-10. doi: 10.5423/PPJ.OA.01.2016.0032. Epub 2016 Aug 01.

Pathogen infection in plants induces complex responses ranging from gene expression to metabolic processes in infected plants. In spite of many studies on biotic stress-related changes in host plants, little is known about the metabolic and phenotypic responses of...

Analysis of concentration-dependent effects of copper and PCB on different Chattonella spp. microalgae (raphidophyceae) cultivated in artificial seawater medium.

EXCLI journal

Niestroy J, Martínez AB, Band-Schmidt CJ.
PMID: 26417254
EXCLI J. 2014 Feb 28;13:197-211. eCollection 2014.

In the present study, the effect on the chlorophyll a and the total protein content as well as the Chattonella spp. cell viability were examined after concentration-dependent exposure to CuCl2 and Aroclor 1242. The comparison between various raphidophyte strains...

Topical Treatment of Aging Hands: Brief Report.

The Journal of clinical and aesthetic dermatology

Roberts WE, Colvan L, Gotz V.
PMID: 28979662
J Clin Aesthet Dermatol. 2017 Aug;10(8):37-41. Epub 2017 Aug 01.

Rejuvenation of aging hands is becoming increasingly important to physicians and their patients. While a variety of invasive treatments are available, topical products that improve manifestations of aging hands are needed. In this brief report, the efficacy of a...

Observation of Electronic Excitation Transfer Through Light Harvesting Complex II Using Two-Dimensional Electronic-Vibrational Spectroscopy.

The journal of physical chemistry letters

Lewis NHC, Gruenke NL, Oliver TAA, Ballottari M, Bassi R, Fleming GR.
PMID: 27704843
J Phys Chem Lett. 2016 Oct 20;7(20):4197-4206. doi: 10.1021/acs.jpclett.6b02280. Epub 2016 Oct 10.

Light-harvesting complex II (LHCII) serves a central role in light harvesting for oxygenic photosynthesis and is arguably the most important photosynthetic antenna complex. In this work, we present two-dimensional electronic-vibrational (2DEV) spectra of LHCII isolated from spinach, demonstrating the...
