“Background Over the last decade, there has been an increasing interest in click here finding new highly efficient thermoelectric materials QNZ solubility dmso for electronic cooling [1–3] and power generation [4–6]. The energy demand in developed and under-developed countries is increasing due to the population growth and the improvement of the standard level of life in emerging countries. Unfortunately, reserves of fossil fuels are not unlimited, and their use generates huge amounts of CO 2 in the atmosphere. Many human activities (power plants, cement plants, steel mills, and vehicles engines as a few examples) are generating high amount of waste heat at different ranges of temperature. The conversion of this waste heat into electric energy would be an important contribution to the sustainable development as it would

allow to reduce both the Greenhouse gas emissions and fossil fuel consumption. Thermoelectric generators are designed to convert a temperature difference into electricity (Seebeck effect) or, inversely, electric energy into a thermal Florfenicol gradient (Peltier effect). Thermoelectric materials must have a high conversion efficiency, and they must also be composed conveniently of non-toxic and abundantly available elemental species having high chemical stability in air. The performance of a thermoelectric material is determined by the dimensionless figure of merit ZT: (1) S being the Seebeck coefficient, σ the electrical conductivity, κ the thermal conductivity, and T the absolute temperature. The power factor (PF) defined as PF≡σ S 2 can be used to compare the relative efficiency when the thermal conductivity is similar in different samples. Over the past 30 years, semiconductor alloys based on Bi 2 Te 3, PbTe, and SiGe [7–9] have been extensively studied and optimized for their use in thermoelectric applications.

Reverse-transcription was performed using RNase H-MMLV reverse transcriptase (Superscript II, Invitrogen, Cergy Pontoise, France) and random hexamers (Amersham, Orsay, France). The resulting cDNA was amplified by real-time RT-PCR (RT-qPCR) using SYBR Green I (ROCHE SAS, Boulogne-Billancourt, France). Primers of the genes are listed in Table selleck chemicals 3. Statistical analysis Data are presented as mean ± standard deviation. Statistical analyses were carried out using Statview version 5.0 (SAS Institute, Cary, North Carolina). The homogeneity of the variances were checked using Barttlet test for equal variances. When the latter was no significant (p > 0.05), data were analysed using one way ANOVA

followed by Bonferroni-Dunn test for the pair-wise comparison. When the variances were different (Barttlet test, p < 0.05) data were analysed using the Kruskal-Wallis test followed by a Mann Whitney test for the pair-wise comparisons.

For the terrestrial habitat, we recorded 256 species, with CP-690550 supplier species richness per group varying greatly, ranging between 7 macrolichen species and 116 fern species (Table 1). The epiphytic habitat was richer in species with a total of 319 species. Liverworts and especially lichens (67 species) were more specious in the epiphytic than in the terrestrial habitat, as opposed to mosses and ferns sampling completeness ranged from 54% for terrestrial lichens to 86% for epiphytic liverworts, and was

higher for epiphytes than for terrestrial taxa (Table 1). Within both habitats, sampling completeness was highest for mosses and ferns, and lowest for lichens. Patterns of species CP673451 price richness at each site varied strongly between taxonomic groups (Fig. 2), with the exception of liverworts and ferns. The latter two resembled each other in species richness per plot and their patterns of alpha diversity were similar in different habitat types. In both forest types, the epiphytic habitat was significantly richer in ferns, liverworts and lichens. Mosses were the only primarily terrestrial group. Mostly, species richness declined from slopes to ridges, with the exception of terrestrial lichens, which were absent on slopes.

RT ridges, terrestrial, SE slopes, epiphytic, RE ridges, epiphytic). Lower case letters designate statistically PF-02341066 in vivo different means (ANOVAs with post-hoc Tukey tests)

The comparison of differences in alpha diversity revealed that epiphytic fern species richness was positively related to that of epiphytic liverworts and mosses (R = 0.64), and liverwort richness to mosses (R = 0.54). However, we found no correlations with epiphytic lichens (Table 2). For terrestrials, only fern and liverwort species richness were significantly correlated to each other. Lichens showed slightly negative correlations with liverworts and completeness Amisulpride (R = 0.87, P = 1).

Ferns were the only group with a significant difference in the relative species richness for the two habitat types (t = 4.84, P < 0.0001). The plot level (alpha 2) of the terrestrial habitat only yielded 12% of regional species richness, as compared to 25% in the epiphytic habitat. Additive patterns of species richness for terrestrial macrolichens were not representative due to the very low sampling completeness.
