Seasonal changes in the abundance and composition of Plant Pigments in particulate organic carbon in the lower Mississippi and pearl rivers
Estuaries and Coasts, 2006Co-Authors: Shuiwang Duan, Thomas S. BianchiAbstract:Plant Pigments in particulate organic carbon were examined in the lower Mississippi and Pearl Rivers (U.S.), along with physical variables and nutrients to study seasonal changes in the abundance and composition of phytoplankton. Water samples were collected monthly from September 2001 to August 2003 in the lower Mississippi River (MR; no samples were taken in February 2002) and from August 2001 to July 2003 in the Pearl River (PR). High concentrations of total suspended solids (TSS), nutrients, and chlorophylla (chla; dominated by diatoms) were observed in the lower MR. The smaller blackwater PR was characterized by lower nutrients and chla, higher ultraviolet absorbance, and a phytoplankton biomass dominated by chlorophytes. Chla concentrations in the lower MR was high in summer low-flow periods and also during interims of winter and spring, and did not couple with physical variables and nutrients, likely due to a combination of in situ production and inputs from reservoirs, navigation locks and oxbow lakes in the upper MR and Missouri River. Chla concentrations in the PR was only high in summer low-flow periods and were controlled by temperature and concentrations of chromophoric dissolved organic matter 9CDOM). The high, diatom-dominated phytoplankton biomass in the lower MR was likely the result of decreasing TSS (increased damming in the watershed) and increasing nutrients (enhanced agricultural runoff) over the past few decades. Lower phytoplankton biomass (dominated by chlorophytes) in the PR was likely linked with intense shading by CDOM and lower availability of nutrient inputs. An increase in the relative importance of phytoplankton biomass in large turbid rivers, such as the MR, could have significant effects on the age and lability of riverine organic matter entering the ocean, the stoichiometric balance of nutrients delivered to coastal margins, and the sequestration of atmospheric CO2 in these dynamic regions.

Cross-shelf changes in phytoplankton community composition in the Gulf of Mexico (Texas shelf/ slope): the use of Plant Pigments as biomarkers
Continental Shelf Research, 1999Co-Authors: Corey D. Lambert, Thomas S. Bianchi, Peter H. SantschiAbstract:Abstract Plant Pigments were used as tracers to document changes in the composition of phytoplankton assemblages in relation to nutrient distributions across the Texas shelf/slope in the northwestern Gulf of Mexico (GOM) on three cruises in June 1992, January 1993 and October 1993. Diatoms, prymnesiophytes, and cyanobacteria dominated the Texas shelf and shelf/slope break waters in January 1993 (ca. 85%), with diatoms and cyanobacteria as the dominant taxa in October 1993 (ca. 90%). In general, diatoms and cyanobacteria dominated the shelf waters while cyanobacteria, pelagophytes, and prymnesiophytes were dominant in slope waters. The highest concentrations of prymnesiophytes, based on 19’ hexanoyloxyfucoxanthin (19-hex) concentrations, were found in slope waters in January 1993 and were likely related to the presence of a warm-core ring at that time. Water column N : P and Si : N ratios in the dissolved phase for the three cruises averaged 11.44±4.46 and 8.67±5.61, respectively. Cyanobacterial abundance was positively correlated with total nitrogen (TN) concentrations in slope waters on all three cruises, indicating that nitrogen-fixing bacteria may have contributed to TN concentrations in Texas slope waters. Based on the range of the ratio of chlorophyll a : diagnostic Pigments ( F p ratios) (0.09–0.34) the overall trophic status of surface waters across the Texas shelf/slope was characterized as oligotrophic. Nutrient concentrations in shelf waters indicated that these waters were not oligotrophic and that the F p -derived trophic status was incorrect. One problem with the application of F p ratios in nearshore systems is that new production may be represented by classes other than dinoflagellates and diatoms, such as cyanobacteria, which if ignored will underestimate new production resulting in an incorrect characterization of eutrophication.

Sources and composition of particulate organic carbon in the Baltic Sea: the use of Plant Pigments and lignin-phenols as biomarkers
Marine Ecology Progress Series, 1997Co-Authors: Thomas S. Bianchi, Carl Rolff, Corey D. LambertAbstract:Water samples were collected in the Baltic Sea, along a north to south transect that extended from Bothnian Bay to the Baltic proper, in July 1994-just after the period of peak freshwater discharge. Plant Pigments and lignin-phenols were used a s biomarkers to determine the dominant sources of phytoplankton and terrestrial inputs along the transect. A distinct gradient in chlorophyll a concentrations that increased from north (2.1 pg I']) to south (18.9 1.19 1-l) indicated that the dominant blooms occurred from the southern Bothnian Sea to the Baltic proper. High fucoxanthin (3.9 pg 1-l) and peridinin (1.9 pg I' ) concentrations In the Bothnian Bay and Sea reflected late stages of diatom and dinoflagellate blooms, respectively, that typically occur in summer months in the northern Baltlc (Andersson et al. 1996). High zeaxanthin (8 pg I-') concentrations in the southern Bothnian Sea and Baltlc proper indicated dominance of cyanobacterial blooms In these regions. Decreasing concentrations of total lignin-phenols ( A ) from north (0.22) to south (0 02) Indicated that terrestrial inputs of organic carbon were associated w ~ t h high freshwater inflow into the northern Baltic. Further examinatlon of lignin-phenol ratios indicated that the dominant source of terrestrial material into the Baltic was from woody gymnosperms.

Plant Pigments as biomarkers of organic matter sources in sediments and coastal waters of Cyprus (eastern Mediterranean)
Estuarine Coastal and Shelf Science, 1996Co-Authors: Thomas S. Bianchi, Andreas Demetropoulos, Myroula Hadjichristophorou, Marina Argyrou, M. Baskaran, Corey D. LambertAbstract:Abstract Plant Pigments (chlorophylls and cartenoids) and radionuclides ( 226 Ra and 210 Pb) were measured in the coastal waters and sediments off the coast of Cyprus (eastern Mediterranean), for the first time, in June and July 1993. Some of the lowest concentrations of chlorophyll a (10–90 ng l −1 ) were found in these highly oliogotrophic waters. Based on the presence of chlorophyll b and zeaxanthin, it appeared that chlorophytes, cyanobacteria, and prochlorophytes were the dominant phytoplankton classes. The phytoplankton assemblage off the coast of Cyprus was not very different when compared to the deeper regions of the eastern Mediterranean. However, there were significantly higher concentrations of Pigments in sediments principally due to seagrasses and macroalgae. In fact the Red Sea migrant Caulerpa racemosa appears to be expanding its areal coverage along the coastline; it remains to be tested whether this is related to enhanced nutrient inputs or to inherent differences in the life-history characteristics of this migrant vs. native species. The very low sedimentation rates observed at all stations (0·38–0·78 mm year −1 ) further suggested that input from the water column to the sediments was minimal. The land-margin effects of Cyprus on the surrounding oligotrophic waters of the eastern Mediterranean appeared to only affect the composition and distribution of benthic macrophytes, with very little change in the phytoplankton assemblages.

Plant Pigments as biomarkers of high molecular weight dissolved organic carbon
Limnology and Oceanography, 1995Co-Authors: Thomas S. Bianchi, Corey D. Lambert, Peter H. Santschi, Mark Baskaran, Laodong GuoAbstract:We used Plant Pigments as tracers of high-molecular-weight dissolved organic C (HMW DOC) ( 1,000 Da). Water samples were collected from four stations along a transect on cruises in June 1992 and January 1993 in the Gulf of Mexico. Samples were also collected from three stations on the continental shelf of Cape Hatteras for comparison. Chlorophylls a and b were at detectable levels in HMW DOC ; concentrations of the carotenoids zeaxanthin and fucoxanthin in HMW DOC indicated that cyanobacteria, prochlorophytes, and diatoms contributed to the total HMW DOC pool across the continental margin in the gulf. The extremely low concentrations ofpheoPigments (except for chlorophyllide) in particulate organic C and HMW DOC suggested that direct exudation from phytoplankton and sloppy feeding by zooplankton were the major mechanisms of release. However, significant and selective pigment loss, due to light and thermal degradation in the reservoir, did occur in the absence of any cooling or light-shielding precautions. This study demonstrated that Pigments can be used to acquire qualitative information on the sources of HMW DOC and to gain insight on its relative age-based on pigment turnover.

Plant Pigments as biomarkers of organic matter sources in sediments and coastal waters of Cyprus (eastern Mediterranean)

Early Diagenesis of Plant Pigments in Hudson River Sediments
Estuarine Coastal and Shelf Science, 1993Co-Authors: Thomas S. Bianchi, Jack E. Dibb, Stuart E. G. FindlayAbstract:Abstract Plant pigment concentrations were measured using high performance liquid chromatography in Hudson River sediments. Sedimentation rates and mixing characteristics were determined from depth profiles of the naturally occurring radionuclides 7Be, 210Pb. Previous estimates of the mean-lives (1/λ) of Plant Pigments (chlorophylls a and b, fucoxanthin) from laboratory experiments, indicate a range of c. 20-40 days. However, in the field, we observed that these Pigments decreased less rapidly with depth and penetrated deeper than 7Be (mean-life 77 days) in Hudson sediments 95% of the time. Assuming similar mixing processes for particles carrying 7Be and Pigments, this indicates that pigment decay rates in the field are slower than the 0·013 day-1 decay rate of 7Be, hence, more than 2-fold slower than the derived laboratory rates. We believe that high inputs of vascular Plant detritus in the Hudson may increase the complexation of humic substances with Pigments resulting in slower decay rates. While most Pigments showed an exponential decrease with sediment depth, lutein concentrations generally increased with depth. This pattern of decay resistance is in agreement with laboratory experiments which show that lutein is the most decay resistant among dominant Pigments. These data along with other studies demonstrate that the carotenoids lacking the 5,6-epoxide group (i.e., lutein) are more decay resistant than Pigments that contain it (i.e., fucoxanthin).

Organic Matter Sources in the Water Column and Sediments of the Hudson River Estuary: the Use of Plant Pigments as Tracers
Estuarine Coastal and Shelf Science, 1993Co-Authors: Thomas S. Bianchi, Stuart E. G. Findlay, Rodger DawsonAbstract:Abstract The purpose of this study was to document inputs of organic matter into the Hudson River Estuary using Plant Pigments as tracers. Plant Pigments (carotenoids and chloroPigments) were determined using high pressure liquid chromatography (HPLC). Water column and sediment samples were collected in 1988 and 1989, from stations along a 165 km transect in the Hudson River Estuary. In the water column, high concentrations of lutein were found at stations adjacent to wetland areas indicating inputs of vascular Plant detritus, particularly during late fall. Chlorophyll b/lutein ratios at these stations were 2-4 which are similar to that found in fresh vascular Plant material collected from the Hudson. Low chlorophyll b/lutein ratios at Haverstraw Bay, a shallow and turbid area of the estuary, indicate high levels of sediment resuspension. Cyanophyte blooms, as indicated by high concentrations of myxoxanthophyll, reach their peak in late summer at the Hudson and Kingston stations. The chlorophyll a from these algae may comprise as much as 78% of the total chlorophyll a pool during these periods. Concentrations of total phaeophorbide, an indicator of grazing activity, were not correlated with chlorophyll a but were correlated with fucoxanthin and/or fucoxanthinol. This correlation suggests that much of the zooplankton grazing activity is associated with high quality food resources such as diatoms and not with cyanophytes. Surface sediments from a coarse-grained sandy habitat had significantly lower amounts of total organic matter than muddy habitats. However, the sandy sediment had higher grazing activity per gram organic matter, as indicated by total phaeophorbides. Higher concentrations of chlorophyll a and fucoxanthin at the sandy habitat indicate the presence of benthic diatoms which are high quality (low C/N ratio) living resources in contrast to the detrital sources (high C/N, mostly vascular Plant) at the muddy stations. High concentrations of chlorophyllide a at some muddy stations, near macrophyte beds, suggest inputs of epiphytic diatom detritus. Overall, sediment Pigments of the Hudson estuary are derived from vascular Plant material that does not reflect the pigment signature of the water column.

experimental degradation of Plant materials in hudson river sediments i heterotrophic transformations of Plant Pigments
Biogeochemistry, 1991Co-Authors: Thomas S. Bianchi, Stuart E. G. Findlay, Dominique FontvieilleAbstract:We examined photopigment degradation and transformation in sediment microcosms that received different detrital source materials (planktonic, littoral, terrestrial) in the presence or absence of amphidpods (Gammarus sp.). Additions of realistic quantities of particulate organic matter resulted in detectable changes in pigment concentration and composition despite insignificant changes in total organic matter. The transformation of chlorophyll a to total phaeophorbide was significantly higher in all high quality (high nitrogen) detritus treatments containing amphipods. The highest production of phaeophorbide was in the higher quality detritus (blue-green algae, Anabaena cylindrica, and macrophyte, Vallisneria americana) when compared to red maple (Acer rubrum). Phaeophytin formation was not related to amphipod grazing and thus may be determined more by microbial heterotrophic processes. The degradation product of the carotenoid lutein, lutein 5,6 expoxide, was formed in all treatments. Phaeopigment composition can be used to infer differences in heterotrophic activity and will help in the interpretation of photopigment distribution in field samples.

photoprotection by Plant extracts a new ecological means to reduce pesticide photodegradation
Journal of Agricultural and Food Chemistry, 2010Co-Authors: Boris Eyheraguibel, Claire Richard, Gerard Ledoigt, Alexandra Ter HalleAbstract:A pesticide's reactivity toward light at the leaf surface after crop treatment is rarely considered, although such degradation reactions directly affect the pesticide's effectiveness. To overcome these limitations, the use of Plant Pigments was proposed as a new class of photoprotecting agent. The photoprotecting properties of seven Plant Pigments were tested under controlled conditions over herbicide sulcotrione. Grape wine extracts were tested over a panel of pesticides from distinct chemical families. The addition of Plant extracts almost systematically reduced the pesticide's photoreactivity. The grape wine extracts improve at least by 38% the half-life of photolysis of almost all of the active ingredients tested, except for the herbicide triclopyr. Fustictree extract increases by 82% the photostability of the herbicide sulcotrione. Plant extracts mainly act as sunscreens; that is, the photostabilization of the active ingredient is due to the competitive energy absorption of UV photon. The use of natu...

Meta-Analysis of the Detection of Plant Pigment Concentrations Using Hyperspectral Remotely Sensed Data
PloS one, 2015Co-Authors: Jingfeng Huang, George Alan Blackburn, Chen Wei, Yao Zhang, Xiuzhen Wang, Chuanwen Wei, Jing WangAbstract:Passive optical hyperspectral remote sensing of Plant Pigments offers potential for understanding Plant ecophysiological processes across a range of spatial scales. Following a number of decades of research in this field, this paper undertakes a systematic meta-analysis of 85 articles to determine whether passive optical hyperspectral remote sensing techniques are sufficiently well developed to quantify individual Plant Pigments, which operational solutions are available for wider Plant science and the areas which now require greater focus. The findings indicate that predictive relationships are strong for all Pigments at the leaf scale but these decrease and become more variable across pigment types at the canopy and landscape scales. At leaf scale it is clear that specific sets of optimal wavelengths can be recommended for operational methodologies: total chlorophyll and chlorophyll a quantification is based on reflectance in the green (550–560nm) and red edge (680–750nm) regions; chlorophyll b on the red, (630–660nm), red edge (670–710nm) and the near-infrared (800–810nm); carotenoids on the 500–580nm region; and anthocyanins on the green (550–560nm), red edge (700–710nm) and near-infrared (780–790nm). For total chlorophyll the optimal wavelengths are valid across canopy and landscape scales and there is some evidence that the same applies for chlorophyll a.

Hyperspectral remote sensing of Plant Pigments.
Journal of experimental botany, 2006Co-Authors: George Alan BlackburnAbstract:The dynamics of pigment concentrations are diagnostic of a range of Plant physiological properties and processes. This paper appraises the developing technologies and analytical methods for quantifying Pigments non-destructively and repeatedly across a range of spatial scales using hyperspectral remote sensing. Progress in deriving predictive relationships between various characteristics and transforms of hyperspectral reflectance data are evaluated and the roles of leaf and canopy radiative transfer models are reviewed. Requirements are identified for more extensive intercomparisons of different approaches and for further work on the strategies for interpreting canopy scale data. The paper examines the prospects for extending research to the wider range of Pigments in addition to chlorophyll, testing emerging methods of hyperspectral analysis and exploring the fusion of hyperspectral and LIDAR remote sensing. In spite of these opportunities for further development and the refinement of techniques, current evidence of an expanding range of applications in the ecophysiological, environmental, agricultural, and forestry sciences highlights the growing value of hyperspectral remote sensing of Plant Pigments.
