Light limited carboxylation rates of Red mangrove leaves at Key Largo, Watson River Chickee, Taylor Slough, and Little Rabbit Key, South Florida (FCE) from July 2001 to August 2001
Our goal is to determine light limited carboxylation rates of red mangrove (specie sRhizophora mangle) leaves. This information will be used to model carbon sequestration by Red mangroves.

Photodegradation of carboxyl DOC from permafrost soils collected from the North Slope of Alaska in the summer of 2015
Dissolved organic carbon (DOC) was leached from permafrost soils near the Toolik Field Station in the Alaskan Arctic and then characterized for its photochemical properties. The photodegradation of carboxyl carbon (C) within permafrost DOC was quantified by 13C nuclear magnetic resonance (NMR).

(DATASET) (10,0) carbon nanotubes functionalized with carboxyl and hydroxyl organic groups
<p>Starting from a (10,0) carbon nanotube, 10 000 structures where randomly generated for both functionalizations (carboxyl, -COOH, and hydroxyl, -OH) and for 5 concentrations of the surface being funcionalized (5%, 10%, 15%, 20% and 25%). Then, the entropy of all system was calculated. The structures with highest entropy on each group/percentage where selected as representative of each functionalization.</p> <p>Here are the structures of functionalized (10,0) carbon nanotubes in MOL2 and XYZ formats.</p> <p>These systems were used in the following publications:</p> <ul> <li>M.S.

Xylomelum occidentale (Proteaceae) accesses relatively mobile soil organic phosphorus without releasing carboxylates
<p>1. Hundreds of Proteaceae species in Australia and South Africa typically grow on phosphorus (P)-impoverished soils, exhibiting a carboxylate-releasing P-mobilising strategy. In the Southwest Australian Biodiversity Hotspot, two <i>Xylomelum </i> (Proteaceae) species are widely distributed, but restricted within that distribution.</p> <p>2. We grew <i>X. occidentale</i> in hydroponics at 1 μM P. Leaves, seeds, rhizosheath and bulk soil were collected in natural habitats.</p> <p>3. <i>Xylomelum occidentale</i> did not produce functional cluster roots and occupied soils that are somewhat less P-impoverished than those in typical Proteaceae habitats in the region. Based on measurements of foliar manganese concentrations (a proxy for rhizosphere carboxylate concentrations) and P fractions in bulk and rhizosheath soil, we conclude that <i>X. occidentale</i> accesses organic P, without releasing carboxylates. Solution <sup>31</sup>P-NMR revealed which organic P forms <i>X. occidentale</i> accessed.</p> <p>4. <i>Xylomelum occidentale</i> uses a strategy that differs fundamentally from that typical in Proteaceae, accessing soil organic P without carboxylates. We surmise that this novel strategy is likely expressed also in co-occurring non-Proteaceae that lack a carboxylate-exuding strategy, and plants in similar habitats. These co-occurring species are unlikely to benefit from mycorrhizal associations, because plant-available soil P concentrations are too low.</p> <p>5. <i>Synthesis.</i> Our findings show the first field evidence of effectively utilising soil organic P by <i>X. occidentale</i> without carboxylate exudation and explain their relatively restricted distribution in an old P-impoverished landscape, contributing to a better understanding of how diverse P-acquisition strategies coexist in a megadiverse ecosystem.</p>
Contrasting patterns in biomass allocation, root morphology and mycorrhizal symbiosis for phosphorus acquisition among 20 chickpea genotypes with different amounts of rhizosheath carboxylates
<p>1. Adjustments in root biomass allocation, root morphology, carboxylate exudation and mycorrhizal symbiosis are well-known strategies for plants to cope with phosphorus (P) deficiency. Large genotypic variation in these functional traits has been demonstrated within numerous species. Yet, whether these functional traits are coordinated differently among genotypes of a species to enhance P acquisition remains unknown.</p> <p>2. We characterised 11 root functional traits associated with P acquisition in 20 chickpea genotypes with contrasting amounts of rhizosheath carboxylates, grown in a glasshouse with severely limiting insoluble (10 mg kg<sup>–1</sup> FePO<sub>4</sub>), moderately limiting soluble (10 mg kg<sup>–1</sup> KH<sub>2</sub>PO<sub>4</sub>), and adequate (50 mg kg<sup>–1</sup> KH<sub>2</sub>PO<sub>4</sub>) P supply.</p> <p>3. Substantial variation was found among genotypes in root functional traits associated with P acquisition. Genotypes with a large amount of carboxylates (HRC) had thinner roots, and a lower root mass fraction and root mass density, but higher specific root length and colonisation by arbuscular mycorrhizal fungi (AMF) than genotypes with a small amount of rhizosheath carboxylates.</p> <p>4. In response to soil P availability, chickpea genotypes showed large plasticity in root biomass allocation, rhizosheath pH, carboxylate amount, and colonisation by AMF, but a limited response in most root morphological traits (i.e. mean root diameter, root mass density and specific root length). Shoot P content was strongly correlated with different root functional traits in the three P treatments.</p> <p>5. Our findings suggest a range of predictable relationships between root functional traits among chickpea genotypes; those with HRC tended to have relatively thinner roots with lower cost of root construction, while allocating more resources to carboxylate exudation and colonisation by AMF. The shift in the relationships between shoot P content and root functional traits indicates that <span class="fontstyle01"><span>root traits and/or trait combinations in chickpea vary in a manner that enhances P acquisition under specific soil P conditions (i.e. P sources/ levels)</span></span>. Such knowledge provides valuable information for chickpea genotype breeding and our understanding of evolution of traits with improved root/rhizosphere functioning.</p> <p> </p>
