Extreme specificity in epiparasitic Monotropoideae (Ericaceae): widespread phylogenetic and geographical structure.
, Molecular Ecology, Vol: 10, Pages: 2285-2295, ISSN: 0962-1083The Monotropoideae (Ericaceae) are nonphotosynthetic plants that obtain fixed carbon from their fungal mycorrhizal associates. To infer the evolutionary history of this symbiosis we identified both the plant and fungal lineages involved using a molecular phylogenetic approach to screen 331 plants, representing 10 of the 12 described species. For five species no prior molecular data were available; for three species we confirmed prior studies which used limited samples; for five species all previous reports are in conflict with our results, which are supported by sequence analysis of multiple samples and are consistent with the phylogenetic patterns of host plants. The phylogenetic patterns observed indicate that: (i) each of the 13 plant phylogenetic lineages identified is specialized to a different genus or species group within five families of ectomycorrhizal Basidiomycetes; (ii) mycorrhizal specificity is correlated with phylogeny; (iii) in sympatry, there is no overlap in mature plant fungal symbionts even if the fungi and the plants are closely related; and (iv) there are geographical patterns to specificity.

Do nutrient additions alter carbon sink strength of ectomycorrhizal fungi?
, New Phytologist, Vol: 151, Pages: 543-550, ISSN: 0028-646XCarbon sink strength differences are examined here between ectomycorrhizal fungi in interaction with additions of ammonium and apatite (a phosphorus- and calcium-containing mineral).Pinus muricata associated with Paxillus involutus and four suilloid isolates (Suillus pungens and members of three Rhizopogon section Amylopogon species groups) were used in microcosm nutrient addition experiments.The associations differed in ectomycorrhizal biomass, mycelial growth rate, biomass and respiration. P. involutus produced the lowest biomass of ectomycorrhizal connections to P. muricata, but it consumed proportionally more carbon per connection and transferred more than twice as much ammonium to the host per unit mycorrhizal biomass. Paxillus also colonized the soil more rapidly and intensely than the other fungi, but its mycelial respiration was lowest. Ammonium and apatite addition resulted in a marked increase in respiration and mycelial biomass, respectively, by the suilloid fungi.The high carbon cost of ammonium uptake is suggested as one explanation for reduced sporocarp production and mycelial growth by ectomycorrhizal fungi commonly found after high levels of nitrogen addition.

Interfacial Tension of Aqueous and Hydrocarbon Systems in the Presence of Carbon Dioxide at Elevated Pressures and Temperatures
The interfacial tension of partially miscible phases, containing H2O andhydrocarbons in the presence of CO2 at elevated pressures and temperatures,has been studied within the context of producing cleaner fossil fuelsby simultaneously tackling greenhouse gas emissions. This is a most relevantproperty inuencing the multiphase reservoir ows associated withenhanced oil recovery (EOR), and carbon capture and storage (CCS). Themain core of the thesis focuses on the experimental investigation of thedependence of interfacial tension on pressure and temperature, for variousmixtures of pure substances relevant to oil- eld conditions and uids. Forthis purpose, a high pressure high temperature (HPHT) apparatus, comprisinga view cell, high pressure capillary tubing connections, and appropriateuid delivery syringe pumps, was used over an operating temperaturerange of (298 to 473)K and at pressures up to 60MPa. The apparatusimplemented the pendant drop method, well suited for the accuratedetermination of uid/liquid interfacial tensions at elevated pressures andtemperatures, linked to a computer-aided drop shape analysis (DSA) system.Measurements were made over a wide range of conditions for the twophasesystems (H2O+CO2), (n-decane+CO2), (n-dodecane+CO2), (n-hexadecane+CO2), (H2O+n-decane) and (H2O+[n-decane+CO2]). Thedi erent isotherms recorded for each system demonstrated systematic trendswith increasing pressure, while the decrease of interfacial tension with temperatureobserved at ambient pressures was usually reversed at elevatedpressures. For the (H2O+CO2) system in particular, the pressure dependenceof interfacial tension demonstrated abrupt changes at certain conditions,associated with the onset of the liquid or supercritical states, abovewhich the interfacial tension was less sensitive to changes in both pressureand temperature. This was not the case for the (n-alkane+CO2) systems,where the interfacial tension reduced with increasing pressure, vanishing asthe two phases be
