Soils and paleosols as archives of natural and anthropogenic environmental changes
No full textThe Fourth International Congress of the European Confederation of Soil Science Societies (ECSSS) ‘EUROSOIL 2012 ‐ Soil Science for the Benefit of Mankind and Environment’ took place in Bari (Italy) on 2–6 July 2012. It aimed to present and discuss many current issues of Soil Sciences, as well as provide an interactive forum for exchange of ideas by bringing together and promoting durable relationships among established and young soil scientists, technical and professional operators, industry and administrative representatives, policy makers and regulators. The session entitled ‘Soils and Sediments as Natural Archives’, convened by Claudio Zaccone, Sylvie Quideau, Alexander O. Makeev and Daniela Sauer, was devoted to recent studies using soils and palaeosols as potential records of both natural and human‐induced processes that occurred during the past centuries to millennia

Strategic male mating effort and cryptic male choice in a scorpionfly
No full textEngqvist L, Sauer KP. Strategic male mating effort and cryptic male choice in a scorpionfly. Proceedings of the Royal Society B. 2001;268(1468):729-735.In animal species with high male mating effort, males often find themselves in a dilemma: by increasing their mating effort, the gain from each copulation increases but simultaneously reduces available resources and, thus, the opportunity for future copulations. Therefore, we expect males to spend less reproductive resources on matings that provide low reproductive potential, thereby saving resources for future copulations, possibly with high-quality females, a sort of cryptic male choice. However, the strength of the trade-off between nvestment in a current mating and resources available for future matings must not be the same for all males. Males with relatively high mating costs should allocate their limited resources more cautiously than males with more plentiful resources. Here, we examine this prediction in the scorpionfly Panorpa cognata. Prior to copulation, males produce a large salivary mass on which females feed during copulation. We show that the production of larger salivary masses leads to longer copulations. Moreover, the size of the salivary gland and salivary mass increases with increasing male condition. However, males in poor condition make a relatively higher mating investment than males in good condition. We therefore expect male condition to influence cryptic male choice. In accordance with our hypothesis, only males in poor condition choose cryptically, producing larger salivary masses in copulations with females of high fecundity

Reconstructing the evolutionary history of the radiation of the land snail genus Xerocrassa on Crete based on mitochondrial sequences and AFLP markers
No full textSauer J, Hausdorf B. Reconstructing the evolutionary history of the radiation of the land snail genus Xerocrassa on Crete based on mitochondrial sequences and AFLP markers. BMC Evolutionary Biology. 2010;10(1): 299.Background: A non-adaptive radiation triggered by sexual selection resulted in ten endemic land snail species of the genus Xerocrassa on Crete. Only five of these species and a more widespread species are monophyletic in a mitochondrial gene tree. The reconstruction of the evolutionary history of such closely related species can be complicated by incomplete lineage sorting, introgression or inadequate taxonomy. To distinguish between the reasons for the nonmonophyly of several species in the mitochondrial gene tree we analysed nuclear AFLP markers. Results: Whereas six of the eleven morphologically delimited Xerocrassa species from Crete are monophyletic in the mitochondrial gene tree, nine of these species are monophyletic in the tree based on AFLP markers. Only two morphologically delimited species could not be distinguished with the multilocus data and might have diverged very recently or might represent extreme forms of a single species. The nonmonophyly of X. rhithymna with respect to X. kydonia is probably the result of incomplete lineage sorting, because there is no evidence for admixture in the AFLP data and the mitochondrial haplotype groups of these species coalesce deeply. The same is true for the main haplotype groups of X. mesostena. The nonmonophyly of X. franciscoi might be the result of mitochondrial introgression, because the coalescences of the haplotypes of this species with some X. mesostena haplotypes are shallow and there is admixture with neighbouring X. mesostena. Conclusion: The most likely causes for the nonmonophyly of species in the mitochondrial gene tree of the Xerocrassa radiation on Crete could be inferred using AFLP data by a combination of several criteria, namely the depth of the coalescences in the gene tree, the geographical distribution of shared genetic markers, and concordance with results of admixture analyses of nuclear multilocus markers. The strongly subdivided population structure increases the effective population size of land snail species and, thus, the likelihood of a long persistence of ancestral polymorphisms. Our study suggests that ancestral polymorphisms are a frequent cause for nonmonophyly of species with a strongly subdivided population structure in gene trees
FÖRSTER TRANSFER CALCULATIONS BASED ON CRYSTAL STRUCTURE DATA FROM Agmenellum quadruplicatum C-PHYCOCYANIN
No full textExcitation energy transfer in C-phycocyanin is modeled using the Forster inductive resonance mechanism. Detailed calculations are carried out using coordinates and orientations of the chromophores derived from X-ray crystallographic studies of C-phycocyanin from two different species (Schirmer et al, J. Mol. Biol. 184, 257–277 (1985) and ibid., 188, 651-677 (1986)). Spectral overlap integrals are estimated from absorption and fluorescence spectra of C-phycocyanin of Mastigocladus laminosus and its separated subunits. Calculations are carried out for the β-subunit, αβ-monomer, (αβ)3-trimer and (αβ)0-hexamer species with the following chromophore assignments: β155 = 's’(sensitizer), β84 =‘f (fluorescer) and α84 =‘m’(intermediate):]:. The calculations show that excitation transfer relaxation occurs to 3=98% within 200 ps in nearly every case; however, the rates increase as much as 10-fold for the higher aggregates. Comparison with experimental data on fluorescence decay and depolarization kinetics from the literature shows qualitative agreement with these calculations. We conclude that Forster transfer is sufficient to account for all of the observed fluorescence properties of C-phycocyanin in aggregation states up to the hexamer and in the absence of linker polypeptides

2. Relationship between files: The main dataset is "NDS_chl.csv" and has chlorophyll-a concentrations for all NDS deployed in the experiment. The 18S_Sequences and 16S_Sequences are the 18S and 16S data from a subset of NDS.We modified an existing stream method to create a novel under-ice approach by deploying nutrient diffusing substrates (single nutrient amendments, nitrogen or phosphorus; combined enrichment of nitrogen and phosphorus) under two different light scenarios (snow covered, reduced light; snow removed, increased light) near the water-ice interface to mimic the habitat of ice-associated photoautotrophs.
The data associated with the nutrient diffusing substrates are: chlorophyll a concentrations, 16S, and 18S.H.M.S received support from NSF grant #1948058Knoll, Lesley, B; Fry, Benton; Hayes, Nicole, M; Sauer, Hailey, M.

Defocused imaging of quantum-dot angular distribution of radiation
No full textPatra D, Gregor I, Enderlein J, Sauer M. Defocused imaging of quantum-dot angular distribution of radiation. APPLIED PHYSICS LETTERS. 2005;87(10):101103.We have applied defocused imaging of single fluorescent quantum dots to study the angular distribution of their emission. It is found that quantum dots exhibit an angular distribution best described by a superposition of emission of three perpendicular dipoles. A theory of the defocused images of such emitters is presented and compared with the measurements. Furthermore, it is shown that standard fluorescence anisotropy measurements are not able to uncover such complex emission behavior. (c) 2005 American Institute of Physics
