Planck 2015 results. XIII. Cosmological parameters

We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. These data are consistent with the six-parameter inflationary LCDM cosmology. From the Planck temperature and lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, a matter density parameter Omega_m = 0.308 +/- 0.012 and a scalar spectral index with n_s = 0.968 +/- 0.006. (We quote 68% errors on measured parameters and 95% limits on other parameters.) Combined with Planck temperature and lensing data, Planck LFI polarization measurements lead to a reionization optical depth of tau = 0.066 +/- 0.016. Combining Planck with other astrophysical data we find N_ eff = 3.15 +/- 0.23 for the effective number of relativistic degrees of freedom and the sum of neutrino masses is constrained to < 0.23 eV. Spatial curvature is found to be |Omega_K| < 0.005. For LCDM we find a limit on the tensor-to-scalar ratio of r <0.11 consistent with the B-mode constraints from an analysis of BICEP2, Keck Array, and Planck (BKP) data. Adding the BKP data leads to a tighter constraint of r < 0.09. We find no evidence for isocurvature perturbations or cosmic defects. The equation of state of dark energy is constrained to w = -1.006 +/- 0.045. Standard big bang nucleosynthesis predictions for the Planck LCDM cosmology are in excellent agreement with observations. We investigate annihilating dark matter and deviations from standard recombination, finding no evidence for new physics. The Planck results for base LCDM are in agreement with BAO data and with the JLA SNe sample. However the amplitude of the fluctuations is found to be higher than inferred from rich cluster counts and weak gravitational lensing. Apart from these tensions, the base LCDM cosmology provides an excellent description of the Planck CMB observations and many other astrophysical data sets

Sensitivity of South American tropical forests to an extreme climate anomaly

This is the final version. Available on open access from Nature Research via the DOI in this recordData availability: Publicly available climate data used in this paper are available from ERA5 (ref. 64), CRU ts.4.03 (ref. 65), WorldClim v2 (ref. 66), TRMM product 3B43 V7 (ref. 67) and GPCC, Version 7 (ref. 68). The input data are available on ForestPlots42.Code availability R code for graphics and analyses is available on ForestPlots42.The tropical forest carbon sink is known to be drought sensitive, but it is unclear which forests are the most vulnerable to extreme events. Forests with hotter and drier baseline conditions may be protected by prior adaptation, or more vulnerable because they operate closer to physiological limits. Here we report that forests in drier South American climates experienced the greatest impacts of the 2015–2016 El Niño, indicating greater vulnerability to extreme temperatures and drought. The long-term, ground-measured tree-by-tree responses of 123 forest plots across tropical South America show that the biomass carbon sink ceased during the event with carbon balance becoming indistinguishable from zero (−0.02 ± 0.37 Mg C ha−1 per year). However, intact tropical South American forests overall were no more sensitive to the extreme 2015–2016 El Niño than to previous less intense events, remaining a key defence against climate change as long as they are protected

Karyotype characterization of two populations of Vernonia geminata (Asteraceae, Vernonieae) using banding and FISH techniques

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)In order to extend our knowledge concerning karyotypes of the genus Vernonia, we applied various techniques of chromosome banding, including AgNOR and triple staining with the fluorochromes CMA/DA/DAPI (CDD), and of fluorescent in situ hybridization (FISH) for the 45S rDNA probe to specimens of two populations of Vernonia geminata collected from an open-pasture area, in southern Brazil. B chromosomes were observed in one of the populations. Both populations of V. geminata presented a pair of CMA(3)(+) terminal bands and one pair of chromosomes with terminal AgNOR banding. The FISH evidenced, in one population, two pairs of small sites of 45S rDNA; these being two small terminal sites and two centromeric sites. In the other population, there was only one pair of small terminal sites and two sites in two B chromosomes, one in each chromosome. There was coincidence of localization between CMA(+) and NOR bands with one of the small terminal sites of 45S rDNA of one chromosome of the normal complement, but not in B chromosomes.11442044212Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Ocorrência de Curvularia lunata em Jurubeba no estado de Alagoas Occurrence of Curvularia lunata on "Jurubeba" in Alagoas State, Brazil

A jurubeba (Solanum paniculatum L.) é um membro da família Solanaceae considerada como uma importante planta invasora em vários estados do Brasil. Esse estudo relata a ocorrência do fungo Curvularia lunata (Wakker) Boedijn causando lesões foliares em jurubeba no estado de Alagoas. Com base nos postulados de Koch demonstrou-se que o isolado obtido foi patogênico a plantas de jurubeba, mas não a outras solanáceas cultivadas como tomate, fumo e pimenta.<br>"Jurubeba" (Solanum paniculatum L.), a member of the Solanaceae family, is considered a weed in several crops grown in many states in Brazil. This study reports the occurrence of the fungus Curvularia lunata (Wakker) Boedijn causing leaf spots on "jurubeba" plants in the State of Alagoas. It was proved based on the Kochs's postulates that the isolate of C. lunata was pathogenic on "jurubeba" plants but not on plants from other solanaceous species such as tomatoes, tobacco, and pepper

Malpighiaceae: correlations between habit, fruit type and basic chromosome number Malpighiaceae: correlações entre hábito, tipo de fruto e número cromossômico básico

The family Malpighiaceae presents species with different habits, fruit types and cytological characters. Climbers are considered the most derived habit, followed, respectively, by the shrubby and arboreal ones. The present study examines the relationship between basic chromosome numbers and the derivation of climbing habit and fruit types in Malpighiaceae. A comparison of all the chromosome number reports for Malpighiaceae showed a predominance of chromosome numbers based on x=5 or 10 in the genera of sub-family Malpighioideae, mainly represented by climbers with winged fruits, whereas non-climbing species with non-winged fruits, which predominate in sub-family Byrsonimoideae, had counts based on x=6, which is considered the less derived basic number for the family. Based on such data, confirmed by statistic assays, and on the monophyletic origin of this family, we admit the hypothesis that morphological derivation of habit and fruit is correlated with chromosome basic number variation in the family Malpighiaceae.<br>A família Malpighiaceae apresenta diferentes tipos de hábito, frutos e caracteres citogenéticos. Em geral, espécies lianas são consideradas as mais derivadas, seguidas, respectivamente, pelas arbustivas e arbóreas. O presente estudo propõe para Malpighiaceae uma relação entre a variação do número cromossômico básico e a derivação do hábito trepador e da morfologia dos frutos. Para estabelecer esta relação analisamos todas as contagens de cromossomos já relatadas para a família Malpighiaceae, sendo que a freqüência relativa destas contagens foi calculada para todos os gêneros estudados. Esta comparação mostrou a predominância de números cromossômicos baseados em x=5 ou 10 na sub-família Malpighioideae, predominantemente composta por lianas com frutos alados, enquanto que espécies de outros hábitos, com frutos não alados, apresentaram contagens baseadas em x=6, considerado o número básico menos derivado para a família, predominante na sub-família Byrsonimoideae. Baseados em consistentes dados estatísticos, e também na origem monofilética da família, admitimos a hipótese de que as derivações do hábito e dos tipos de fruto estão diretamente relacionadas com a variação do número cromossômico na família Malpighiaceae
