Although a variety of leaf characteristics appear to be induced by light environment during development, analysis of ontogenetic changes in living broad leaved trees has suggested that a number of other traits also lumped into the classic '...
Biomineralization by photosynthetic organisms: evidence of coevolution of the organisms and their environment? [0.03%]
光合生物的生物矿化作用：共同进化的证据？

The ratio of dissolved fixed inorganic nitrogen to soluble inorganic phosphate (N:P) in the ocean interior is relatively constant, averaging approximately 16 : 1 by atoms. In contrast, the ratio of these two elements spans more than six ord...
Bacterial, archaeal and eukaryotic diversity of smooth and pustular microbial mat communities in the hypersaline lagoon of Shark Bay [0.03%]
鲨湾高盐泻湖平滑型和脓胞型微生物垫群落的细菌、古菌和真核生物多样性研究
M A Allen,F Goh,B P Burns et al.
M A Allen et al.
The bacterial, archaeal and eukaryotic populations of nonlithifying mats with pustular and smooth morphology from Hamelin Pool, Shark Bay were characterised using small subunit rRNA gene analysis and microbial isolation. A highly diverse ba...
Spatiotemporal distribution of microbial communities in a coastal, sandy aquifer system (Doñana, SW Spain) [0.03%]

S Velasco Ayuso et al.
The aquifer system of Doñana (SW Spain) represents the most important freshwater source in the Doñana Natural Area. Its spatiotemporal dynamics favours the hydrological connection between surface and subsurface ecosystems, and promotes ma...
Alteration textures in terrestrial volcanic glass and the associated bacterial community [0.03%]
陆地火山玻璃中的变质纹理及其相关的细菌群落

C S Cockell et al.
Alteration textures were examined in subglacial (hyaloclastite) deposits at Valafell, Southern Iceland. Pitted and 'elongate' alteration features are observed in the glass similar to granular and tubular features reported previously in deep...
Preliminary characterization and biological reduction of putative biogenic iron oxides (BIOS) from the Tonga-Kermadec Arc, southwest Pacific Ocean [0.03%]
西南太平洋汤加-克马德克弧的类生物成因铁氧化物的初步表征及生物还原性研究

L R Croal,Y Jiao,A Kappler et al.
L R Croal et al.
The effect of hydrogen on the rate of phototrophic Fe(II) oxidation by two species of purple bacteria was measured at two different bicarbonate concentrations. Hydrogen slowed Fe(II) oxidation to varying degrees depending on the bicarbonate...
