Environmental parameters and tree physiology in two semiarid land use systems in Brazil

To determine if reduced tree densities(number of trees per unit area) lead to changes in micro-meteorological and tree physiological characteristics, two areas with different tree densities were assessed. One was an agrosilvopastoral system(AGP) with low tree density, and the other, a secondary forest(SF) with greater tree numbers, both located in a semiarid region of Brazil. Data were collected simultaneously by two automated weather stations: rainfall, air(T_a) and soil temperatures(T_(s5 cm)), relative humidity(RHair), photosynthetically active radiation(PAR), soil moisture at two depths(M_(s30 cm)and M_(s50 cm)),and wind velocity(Vw). Net photosynthesis in Cordia oncocalyx Allema?o trees was measured with an infrared gas analyzer in February, March, May, July, August and September 2011, which encompasses a rainy period followed by a dry period. Average values of Ta, T_(s5 cm), Vwand PAR were greater and average values of RHairand M_(s50 cm) were lesser in the AGP. Photosynthetic rates were greater in plants growing under the AGP at the onset of the dry season when Vw, PAR and T_(s5 cm)were greater and M_(s50 cm) was lesser. Photosynthetic rates correlated strongly with physical parameters during the dry season, especially under SF. Differences in tree numbers between AGP and SF led to differences in physical environmental parameters;however, the latter had less influence on photosynthetic rates in C. oncocalyx during the rainy season. During the dry season, all physical parameters had an impact on net photosynthesis under SF but not under AGP. This indicates a certain independence of plants in AGP.

Norite and charnockites from the Venda Nova Pluton,SE Brazil:Intensive parameters and some petrogenetic constraints

Geoscience Frontiers 2012年第6期3卷 789-800页

作者： Julio Cezar mendes Cristina M.P.de Campos departamento de Geologia IGEOUniversidade Federal do Rio de Janeiro21910-949Cidade UniversitariaRio de JaneiroBrazil department of Earth and Environmental Sciences GeoCenterLudwig Maximillians UniversitatTheresienstrasse 41/III80333 MunichGermany

The Venda Nova Pluton （VNP） is a zoned ring structure emplaced in the southern portion of the Neoproterozoic Araquai Belt, in Espirito Santo, Brazil. It is a slightly westward tilted cylinder-like intrusion, with an almost circular horizontal section. In the center of this structure, an off-centered gabbro-noritic core, surrounded by syeno-monzonitic rocks, intrudes an outer ring of charnockites and norite. These envelop the syeno-monzonitic and gabbro-noritic center, as a narrow discontinuous belt. While, in the core intrusion, mingling and mixing processes are widespread and well documented in the literature, in the outer ring, the norite and charnockite layers show predominantly homogeneous and isotropic internal structures. Nevertheless, smaller interaction zones between charnockites and norite denote a comparatively more restricted mingling process. The norite is a fine-grained rock with hypidio- morphic granular to intergranular texture. The charnockites are medium-grained and made up of：（a） orthopyroxene-tonalite, （h） orthopyroxene-quartz-diorite, and （c） orthopyroxene-granodiorite with hy- pidiomorphic granular to porphyritic textures. In all lithotypes both ortho- and clinopyroxene are replaced by hornblende and biotite. Two contrasting compositional sequences have been recognized, based on whole rock geochemistry：（1） a basic, with tholeiitic affinities （norite） and, （2） an intermediate, medium-K calc-alkalinc, comprising the charnockites. Estimated crystallization temperatures, which have been calculated from micro-probe analysis of pyroxenes, range from 915± 25 ℃ to 960 ± 50 ℃. Re-equilibration temperature （ihnenite-magnetite calibration） is around 600 ~ 50 ℃. This indicates oxygen fugacities four order of magnitude below the FMQ-buffer and a reduced environment. Coeval pressure conditions estimated from the Al-content in hornblende range from 5.5 ± 0.6 kbar. Data obtained for the norite point toward an evolution from the partial melting of an anhydrous

Objective This paper aims to evaluate the genotoxicity in peripheral blood lymphocytes of rats after exposure to sunlight at different time points of day in a tropical region of Brazil（5oS,42oW）.Materials and Methods Thirty Wistar-Hannover rats,three months old,were randomly divided into three groups of 10 animals each：Group I [control,without exposure to ultraviolet（UV） radiation],Group II（exposed to sunlight during 08：00 *** 10：00 a.m.）,and Group III（exposed to sunlight during 10：00 *** 12：00 a.m.）.After a week of exposure,peripheral blood samples were taken from the tail of these animals to prepare smears on two slides per *** 24 h after exposure to sunlight in Group III,a new collection was obtained to observe the repair *** alkaline comet assay was used in this study to evaluate the genotoxic activity of sunlight（P0.05）.Results There was no statistical difference between Group I and II（P=0.672）.On the other hand,the exposure to sunlight in Group III showed genotoxic action in comparison to the other groups（P0.0001）.Also,there was no significant repair in Group III R（P=0.407）.Conclusion This study has shown a genotoxic potential of sunlight（UVA-B） in lymphocytes of mammals from 10：00 *** 12：00 a.m.,due to a higher intensity of UV in this tropical region.
