It has recently been shown that Southern Ocean phytoplankton species have evolved to optimize their light-harvesting potential without increasing the high iron-requiring proteins used for photosynthesis. We measured molecular and physiological responses of cultures under a combination iron light conditions. While iron-replete mostly increased biovolume, photochemical efficiency (Fv/Fm) relative...

Abstract Single-cell phase-contrast tomography promises to become decisive for studying 3D intracellular structures in biology. It involves probing cells with light at wide angles, which unfortunately requires complex systems. Here we show an intriguing concept based on inherent natural process plants biology, i.e., dehydration, allowing us easily obtain 3D-tomography of onion-epidermal cells’ ...

Recently, in situ YSI EXO2 phycocyanin fluorescence probes have been widely deployed as a means to determine cyanobacterial abundance drinking water sources, yet few studies evaluated the effects of natural organic matter (NOM) and ambient temperature on probe readings. In this study, Suwannee River NOM was added laboratory cultivated species test performance probe. The impact by monitoring ext...

Long-term protection of arid ecosystems changes the vegetation and soil structures. The quantification aboveground biomass carbon content are among principal indicators to evaluate these changes. Most methods used quantify parameters costly, time consuming destructive. In this paper, two non-destructive were compared: digital image processing biometric measurements. Aboveground five perennial s...

Abstract Harmful algal blooms (HABs), in particular those consisting of the cyanobacteria Microcystis , are becoming increasingly more common across globe. Despite growing body evidence that suggests vertical heterogeneity can be a precursor to HAB formation, abiotic drivers distribution poorly understood field environment. The prediction subsurface is also pertinent because concentrations not ...

Abstract The objective of this study was to identify correlations between environmental variables and cyanobacterial diversity, succession dominance in three Australian water supply reservoirs. We assessed up 15 years in-lake quality monitoring data from Lake Wivenhoe Tingalpa (Queensland), Myponga (South Australia). Lakes Tingalpa, subject a subtropical climate, had higher richness than temper...
