title: The interplay of land forms and disturbance intensity drive the floristic and functional changes in the dry Puna pastoral systems (southern Peruvian Andes)

description: In the Peruvian highlands, climate change and inadequate management are causing land degradation and collapse of the pastoral system. Our research project was aimed at assessing the impact of grazing on dry Puna ecosystem, as understanding and predicting vegetation changes in harsh environments in the face of different disturbance regimes is required for aware and effective management. The study area was the Salinas and Aguada Blanca National Reserve. Two experimental areas were selected, characterized by deep soils with gentle slopes and by shallow soils with steeper slopes. In each area, sites with low and high disturbance regimes were identified, and vegetation was sampled using 10 × 10 m plots. The results indicated that the environmental constraints have a marked influence on the species composition, while disturbance quantitatively affects diversity. The floristic changes observed under different disturbance intensities are mainly related to the functional differentiation of the plant communities and to the decrease in vegetation cover. These processes pose a serious risk to the livelihood of the local people, because they can lead to the loss of biodiversity and economic value of pastures, as well as to soil erosion.

title: A floristic survey of marine tube-forming diatoms reveals unexpected diversity and extensive co-habitation among genetic lines of the <i>Berkeleya rutilans</i> complex (Bacillariophyceae)

description: Limited molecular data for marine tube-forming diatoms are available currently and this study provides the first molecular survey of these taxa. To conduct this survey, we used a molecular-assisted alpha taxonomy (MAAT) approach that utilizes DNA barcode data. We used three DNA barcode markers: the 3´ end of the large subunit of RUBISCO (<i>rbc</i>L-3P); the variable D2/D3 region of the nuclear large subunit ribosomal DNA (LSU D2/D3); and the internal transcribed spacer 2 (ITS2) to assign marine tube-forming diatoms from Canada to genetic species groups. The <i>rbc</i>L-3P analysis uncovered 29 genetic groups including representatives of <i>Haslea crucigera, Navicula bottnica, N. brunelii, N. ramosissima, Nitzschia fontifuga, N. tubicola, Parlibellus berkeleya</i> and <i>P. delognei</i> f. <i>elliptica</i>, as well as a complex of 14 closely related groups morphologically consistent with <i>Berkeleya rutilans</i>. We sequenced ITS2 for representatives of the <i>B. rutilans</i> complex; these data were consistent with the <i>rbc</i>L-3P genetic clusters for 86% of the colonies tested. The remaining 14% were in conflict, possibly indicating that more than a single <i>Berkeleya</i> genetic species was present in each colony. To investigate this hypothesis further, we developed ‘species-specific’ ITS2 primers and confirmed heterogeneity of <i>Berkeleya</i> genetic species in 64% of the colonies tested (<i>N</i> = 91). Therefore, a taxonomic assessment of tube-forming species that were originally described on the basis of colony morphology (e.g. <i>Berkeleya rutilans</i>) can only proceed using clonal cultures or single-cell analysis.

title: Diversity and distribution of foliose Bangiales (Rhodophyta) in West Greenland: a link between the North Atlantic and North Pacific

description: Greenland is a continental island in the northern part of the North Atlantic where the foliose Bangiales flora is poorly known. It is an important area for the study of algal biogeography because of the region’s glacial history, in which Greenland has been alternately exposed to or isolated from the North Pacific via the Bering Strait. A molecular study using 3′ <i>rbc</i>L + 5′ <i>rbc</i>L–S sequences was undertaken to assess the diversity of foliose Bangiales on the west coast of Greenland and <i>rbc</i>L sequences were used to study the Greenland flora in a larger phylogenetic and floristic context. New and historic collections document seven species in four genera from the west coast of Greenland. All species had a close link to North Pacific species, being either conspecific with them or North Atlantic–North Pacific vicariant counterparts.

title: Lichen-symbiotic cyanobacteria associated with <i>Peltigera</i> have an alternative vanadium-dependent nitrogen fixation system

description: In past decades, environmental nitrogen fixation has been attributed almost exclusively to the action of enzymes in the well-studied molybdenum-dependent nitrogen fixation system. However, recent evidence has shown that nitrogen fixation by alternative pathways may be more frequent than previously suspected. In this study, the nitrogen fixation systems employed by lichen-symbiotic cyanobacteria were examined to determine whether their diazotrophy can be attributed, in part, to an alternative pathway. The mining of metagenomic data (generated through pyrosequencing) and PCR assays were used to determine which nitrogen-fixation systems are present in cyanobacteria from the genus <i>Nostoc</i> associated with four samples from different geographical regions, representing different lichen-forming fungal species in the genus <i>Peltigera</i>. A metatranscriptomic sequence library from an additional specimen was examined to determine which genes associated with N<sub>2</sub> fixation are transcriptionally expressed. Results indicated that both the standard molybdenum-dependent system and an alternative vanadium-dependent system are present and actively transcribed in the lichen symbiosis. This study shows for the first time that an alternative system is utilized by cyanobacteria associated with fungi. The ability of lichen-associated cyanobacteria to switch between pathways could allow them to colonize a wider array of environments, including habitats characterized by low temperature and trace metal (e.g. molybdenum) availability. We discuss the implications of these findings for environmental studies that incorporate acetylene-reduction assay data.

title: A combined barcode and morphological approach to the systematics and biogeography of <i>Laurencia pyramidalis</i> and <i>Laurenciella marilzae</i> (Rhodophyta)

description: In the present study we undertook an integrative approach, using both morphological and molecular data (COI-5P + <i>rbc</i>L), to assess the presence of <i>Laurencia pyramidalis</i> in Lusitanian Macaronesia. We studied type material of <i>L. pyramidalis</i> from the herbarium of the Naturalis Biodiversity Center, the Netherlands, and designated a lectotype and syntypes. Vegetative and reproductive features of <i>L. pyramidalis</i> were observed and we included a specimen from the type locality in our molecular analyses. We also investigated the geographical distribution of <i>Laurenciella marilzae</i>, a species recently described from the Canary Islands. Barcode sequences (COI-5P and <i>rbc</i>L) were generated for <i>L. pyramidalis</i> from the type locality (Normandy, France), the Azores, Madeira and the Canary Islands, and for <i>L. marilzae</i> from its type locality (Tenerife, Canary Islands), the Azores and Brazil.

title: Three-dimensional cubic ordered mesoporous carbon (CMK-8) as highly efficient stable Pd electro-catalyst support for formic acid oxidation

description: In this work, Pd nanoparticles were supported on two types of three-dimensional cubic highly ordered<br>mesoporous carbon (CMK-8) by the sodium borohydride reduction method and the activity of the Pd/<br>CMK-8 electro-catalysts towards formic acid oxidation was evaluated and compared with that of<br>commercial Pd/C (E-TEK) catalyst. The catalysts were characterized by transmission electron microscopy<br>(TEM), X-ray diffraction (XRD), cyclic voltammetry, and chronoamperometry. Cyclic voltammetry<br>revealed Pd/CMK-8 with larger pores as being the most electroactive with a mass specific activity<br>(mA mgPd<br> 1) of 486.4 that exceeded not only that of the Pd/C (E-TEK) (386.5 mAmgPd<br> 1) but also that of<br>recently reported Pd/CNT (200 mAmgPd<br> 1), Pd/Graphene (210mAmgPd<br> 1) and Pd/Vulcan XC 72 (193mAmgPd<br> 1).<br>As demonstrated with chronoamperometry, the larger pore Pd/CMK-8 also proved to be the most stable<br>catalyst. This exceptional performance can be ascribed to the very high surface area and Ia3d symmetry<br>that yields a relatively isotropic graphitized structure with a high conductivity. In addition, the open<br>framework of the 3-D bicontinous channels and highly ordered mesopores allows for an advanced mass<br>transfer characteristics. The results show that CMK-8 support would significantly improve the power<br>output and stability of Pd-based electro-catalysts for formic acid oxidation
