Abstract
A WO3@PANI heterojunction photocatalyst with a various mass ratio of polyaniline to WO3 was obtained via the in situ oxidative deposition polymerization of aniline monomer in the presence of WO3 powder. The characterization of WO3@PANI composites was carried via X-ray diffraction (XRD), scanning electron microscopy (SEM-EDS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible diffuse reflection spectroscopy (DRS), X-ray photoelectron spectroscopy (XPS) and photoluminescence spectroscopy (PL). The photocatalytic efficiency of WO3@PANI photocatalysts was assessed by following the decomposition of the Rhodamine B (RhB) dye under visible light irradiation (λ >420 nm). The results evidenced the high efficiency of the WO3@PANI (0.5 wt %) nanocomposite in the photocatalytic degradation of RhB (90% within 120 min) under visible light irradiation 3.6 times compared to pure WO3. The synergistic effect between PANI and WO3 is the reason for the increased photogenerated carrier separation. The superior photocatalytic performance of the WO3@PANI catalyst was ascribed to the increased visible light in the visible range and the efficient charge carrier separation. Furthermore, the Density Functional Theory study (DFT) of WO3@PANI was performed at the molecular level, to find its internal nature for the tuning of photocatalytic efficiency. The DFT results indicated that the chemical bonds connected the solid-solid contact interfaces between WO3 and PANI. Finally, a plausible photocatalytic mechanism of WO3@PANI (0.5 wt %) performance under visible light illumination is suggested to guide additional photocatalytic activity development.

Abstract
Semiconductor photocatalysis is regarded as most privileged solution for energy conversion and environmental application. Recently, photocatalysis methods using bismuth-based photocatalysts, such as BiPO4, have been extensively investigated owing to their superior efficacy regarding organic pollutant degradation and their further mineralization into CO2 and H2O. It is well known that BiPO4 monoclinic phase exhibited better photocatalytic performance compared to Degussa (Evonik) P25 TiO2 in term of ultraviolet light driven organic pollutants degradation. However, its wide band gap, poor adsorptive performance and large size make BiPO4 less active under visible light irradiation. However, extensive research works have been conducted in the past with the aim of improving visible light driven BiPO4 activity by constructing a series of heterostructures, mainly coupled with π-conjugated architecture (e.g., conductive polymer, dye sensitization and carbonaceous materials). However, a critical review of modified BiPO4 systems using π-conjugated materials has not been published to date. Therefore, this current review article was designed with the aim of presenting a brief current state-of-the-art towards synthesis methods of BiPO4 in the first section, with an especial focuses onto its crystal-microstructure, optical and photocatalytic properties. Moreover, the most relevant strategies that have been employed to improve its photocatalytic activities are then addressed as the main part of this review. Finally, the last section presents ongoing challenges and perspectives for modified BiPO4 systems using π-conjugated materials.

Abstract
The Ciminalis section of Gentiana comprises seven species, two of them growing on siliceous substrates (G. alpina and G. acaulis), the other ones being calcareous taxa (G. clusii, G. angustifolia, G. ligustica, G. occidentalis and G. dinarica). A total of 515 individuals from 183 populations over the entire Ciminalis distribution range was analyzed using four chloroplast loci (trnH-psbA, matK, rpoB and rpoC1) and the nuclear ribosomal marker ITS2. The siliceous species display only two chloroplast haplotypes each and are both characterized by patterns of range expansions all over the Alps. Conversely, the calcareous species are on average more diverse (two to 13 haplotypes per species) with strong patterns of local structuring. We suggest that the occurrence of many calcareous refugia at the periphery of the Alps must have led to local adaptation and morphological diversification, and helped preserving intraspecific diversities during the last glaciations for the associated taxa. ITS2 was more efficient in delineating species boundaries than the chloroplast markers for which several haplotypes are shared among species. This might be either due to chloroplast capture among species and/or to recent divergence. Species adapted to the same substrate are generally only distantly related when they co-occur in the same place. For both types of markers, G. clusii is found genetically distant from all other species.

Abstract
This study puts together genetic data and an approximate bayesian computation (ABC) approach to infer the time at which the tree Geoffroea spinosa colonized the Galápagos Islands. The genetic diversity and differentiation between Peru and Galápagos population samples, estimated using three chloroplast spacers and six microsatellite loci, reveal significant differences between two mainland regions separated by the Andes mountains (Inter Andean vs. Pacific Coast) as well as a significant genetic differentiation of island populations. Microsatellites identify two distinct geographical clusters, the Galápagos and the mainland, and chloroplast markers show a private haplotype in the Galápagos. The nuclear distinctiveness of the Inter Andean populations suggests current restricted pollen flow, but chloroplast points to cross-Andean dispersals via seeds, indicating that the Andes might not be an effective biogeographical barrier. The ABC analyses clearly point to the colonization of the Galápagos within the last 160,000 years and possibly as recently as 4750 years ago (475 generations). Founder events associated with colonization of the two islands where the species occurs are detected, with Española having been colonized after Floreana. We discuss two nonmutually exclusive possibilities for the colonization of the Galápagos, recent natural dispersal vs. human introduction.

Abstract
Primers for four loci that amplify cpDNA regions have been designed for population genetic analyses in Dicranum scoparium Hedw. and compared with trnL(UAA)5'exon-trnF. All loci showed intraspecific variation with a number of haplotypes ranging between two and six. trnH-psbA(Dic) showed an intercontinental disjunction, but no variability within the four Swiss populations surveyed, whereas the three remaining loci displayed intrapopulation variability in at least one population (rps19-rpl2, rpoB, trnT-rps4). These primers were additionally tested on 22 bryophytes and three fern species. The primers amplified mostly in mosses and liverworts, but less well in ferns, pointing to their evolutionary distance from the bryophytes.

Abstract
Today, the Seasonally Dry Tropical Forests (SDTF) of eastern South America occur as large, well-defined nuclei (e.g. Caatinga in the northeast) and as smaller enclaves within other vegetations (e.g. Cerrado and Chaco). In order to infer the way the present SDTF distribution was attained, the genetic structure of Astronium urundeuva, a tree confined to SDTF, was assessed using two chloroplast spacers and nine microsatellite loci. Five haplotypes were identified, whose distribution was spatially structured. The distribution of the two most common and divergent haplotypes suggested former vicariance and progressive divergence due to isolation. More recent range expansions of these two lineages subsequently occurred, leading to a secondary contact at the southern limit of the Caatinga SDTF nucleus. The multilocus-Bayesian approach using microsatellites consistently identified three groups of populations (Northeast, Central and Southwest). Isolation by distance was found in Northeast and Southwest groups whereas admixture was detected in the Central group, located at the transition between Caatinga and Cerrado domains. All together, the results support the existence of range expansions and secondary contact in the Central group. This study provides arguments that favour the existence of a previously more continuous formation of SDTF in eastern South America.

Abstract
We studied the phylogeography of Eryngium alpinum by sequencing two intergenic chloroplast spacers, trnH-psbA and trnS-trnG (1322 bp). The sampling design included 36 populations and 397 individuals spanning the entire distribution range of the species, from France to Bosnia. Twenty-one haplotypes were characterized and polymorphism was observed both within and among populations. Population differentiation was strong (F(ST) = 0.92) and largely explained by the distinction of five geographic regions: Southwestern, Western, Middle, Eastern Alps and Balkans (F(CT) = 0.62). Moreover, N(ST) was significantly higher than G(ST) (P < 0.05), showing the existence of a phylogeographic pattern. Six major lineages were recognized using samova and median-joining networks. One lineage, highly divergent from the other ones, was only found in the Balkans and probably persisted in situ during last glaciations. All other lineages might have survived in a Southwestern refugium (Mercantour) and colonized the entire Alpine arc (Southwestern, Western, Middle and Eastern Alps) through repeated colonization events at different time periods. This is the first empirical study suggesting Southern refugia for calcareous Alpine plants, although the existence of a secondary refugium in northern Italy/Austria is also suspected. We also observed recent haplotype diversification, especially in the Southwestern Alps.

Abstract
Twelve microsatellites were isolated from a partial genomic library of Ostrea edulis using (GA/TC)n and (AC/GT)n probes and were subsequently sequenced. We estimate that, on average, 12,700 (GA/TC)n and 3900 (AC/GT)n microsatellites could be found in the genome assuming a random distribution. These estimates are high enough for the construction of a saturated genetic map. Primers were designed for three microsatellite loci, and analyses of polymorphism in a wild cohort revealed that one was suitable for population genetics studies (5 alleles), while the other two were highly polymorphic (between 17 and 48 alleles) and thus were more useful for paternity testing. Mendelian inheritance was tested on two full-sib families, and significant distortions of genotypic frequencies were found, although the gametic distributions seemed to be in agreement with Mendelian expectations. We interpret this as evidence for zygotic selection.

Abstract
Two-factor mating designs at consecutive Sn and S(n+1) levels (S0 and S1 S1 and S2, or F2 and F3) allow estimation of all components of the variation among homozygous lines and F1 hybrids that can be derived from a given population. They also allow for the prediction of the mean of these lines and single-cross hybrids. Some tests for the presence of epistasis are possible at the levels of means and of variances. Such mating designs can be very useful for predicting the value of the best possible lines or the best possible F1 hybrids when it is difficult to produce, at an experimental level for exploratory purposes, either lines or hybrids.
