Doses, fontes e épocas de aplicação de nitrogênio influenciando teores de clorofila e produtividade do trigo

To achieve high wheat yield, correct management of N fertilization and the use of high yield potential cultivars are necessary. The aim of this study was to evaluate the effects of different application rates and sources of N, applied totally at sowing or in topdressing, on grain yield and yield components of two irrigated wheat cultivars under a no-till system, grown in a Cerrado (Brazilian tropical savanna) region of low altitude. A randomized block design was used in a 5 x 3 x 2 x 2 factorial arrangement with three replications, combining five levels of N (0, 50, 100, 150, and 200 kg ha(-1)), three sources of N (Entec (R), ammonium sulfate, and urea), and two application times (at sowing, near the rows, or in topdressing) in two wheat cultivars (IAC 370 and Embrapa 21). The wheat cultivars had similar grain yields. There was no difference among the sources of N for grain yield and yield components. The N applied totally at sowing did not differ from the traditional application at sowing and in topdressing for production of irrigated wheat in no-tillage. The increase in application rates of N increased the leaf N contents and chlorophyll, plant height, and the number of ears per m(2). Grain yield of the wheat cultivars IAC 370 and Embrapa 21 increased up to the application rates of 134 and 128 kg ha(-1) of N, respectively, regardless of application time and source of N. The positive correlation between chlorophyll leaf content and grain yield in accordance with N fertilization levels indicates that N fertilization in topdressing can be recommended based on SPAD readings of leaf chlorophyll performed at 38 days after wheat plant emergence.

Effect of gamma irradiation on caprolactam migration from multilayer polyamide 6 films into food simulants: development and validation of a gas chromatographic method

A GC method to determine caprolactam in water, 15 ethanol, and olive oil food simulants was developed and validated. Linear ranges varied from 0.96 to 642.82 g/mL for water, 0.64 to 800.32 g/mL for 15 ethanol, and 1.06 to 1062.34 g/g for olive oil, with correlation coefficients higher than 0.999. Method precision studies showed RSD values lower than 5.45, while method accuracy studies showed recovery from 72 to 111 for all simulants. The effect of gamma irradiation on caprolactam migration from multilayer polyamide 6 (PA-6) films intended for cheese into water, 15 ethanol, olive oil, and 3 acetic acid simulants was also studied. For migration assay, non-irradiated and irradiated (12 kGy) films were placed in contact with the simulant and exposed at 40C for 10 days. The validated method was used to quantify caprolactam migration from multilayer PA-6 films into the simulants, which ranged from 1.03 to 7.59 mg/kg for non-irradiated films, and from 4.82 to 11.32 mg/kg for irradiated films. Irradiation caused almost no changes in caprolactam levels, with the exception of olive oil, which showed an increase in the caprolactam level. All multilayer PA-6 films were in accordance with the requirements of the legislation for caprolactam migration.

Barshalder 1 : A cemetery in Grötlingbo and Fide parishes, Gotland, Sweden, c. AD 1-1100. Excavations and finds 1826-1971

The prehistoric cemetery of Barshalder is located along the main road on the boundary between Grötlingbo and Fide parishes, near the southern end of the island of Gotland in the Baltic Sea. The cemetery was used from c. AD 1-1100. The level of publication in Swedish archaeology of the first millennium AD is low compared to, for instance, the British and German examples. Gotland’s rich Iron Age cemeteries have long been intensively excavated, but few have received monographic treatment. This publication is intended to begin filling this gap and to raise the empirical level of the field. It also aims to make explicit and test the often somewhat intuitively conceived results of much previous research. The analyses deal mainly with the Migration (AD 375–540), Vendel (AD 520–790) and Late Viking (AD 1000–1150) Periods. The following lines of inquiry have been prioritised. 1. Landscape history, i.e. placing the cemetery in a landscape-historical context. (Vol. 1, section 2.2.6) 2. Migration Period typochronology, i.e. the study of change in the grave goods. (Vol. 2, chapter 2) 3. Social roles: gender, age and status. (Vol. 2, chapter 3) 4. Religious identity in the 11th century, i.e. the study of religious indicators in mortuary customs and grave goods, with particular emphasis on the relationship between Scandinavian paganism and Christianity.. (Vol. 2, chapter 4) Barshalder is found to have functioned as a central cemetery for the surrounding area, located on peripheral land far away from contemporary settlement, yet placed on a main road along the coast for maximum visibility and possibly near a harbour. Computer supported correspondence analysis and seriation are used to study the gender attributes among the grave goods and the chronology of the burials. New methodology is developed to distinguish gender-neutral attributes from transgressed gender attributes. Sub-gender grouping due to age and status is explored. An independent modern chronology system with rigorous type definitions is established for the Migration Period of Gotland. Recently published chronology systems for the Vendel and Viking Periods are critically reviewed, tested and modified to produce more solid models. Social stratification is studied through burial wealth with a quantitative method, and the results are tested through juxtaposition with several other data types. The Late Viking Period graves of the late 10th and 11th centuries are studied in relation to the contemporary Christian graves at the churchyards. They are found to be symbolically soft-spoken and unobtrusive, with all pagan attributes kept apart from the body in a space between the feet of the deceased and the end of the over-long inhumation trench. A small number of pagan reactionary graves with more forceful symbolism are however also identified. The distribution of different 11th century cemetery types across the island is used to interpret the period’s confessional geography, the scale of social organisation and the degree of allegiance to western and eastern Christianity. 11th century society on Gotland is found to have been characterised by religious tolerance, by an absence of central organisation and by slow piecemeal Christianisation.

Neogene and Pleistocene fossil brachiopods of the Eastern Islands. Current appointments.

[EN] Numerous specimens of fossil brachiopods have been found in the different fossiliferous outcrops of the Canary Islands. These fossils have been found in the deposits of Mio-Pliocene age of the eastern Canary Islands, described and illustrated in the work of Meco et ali. 2005 and in the outcrops interpreted as a tsunami deposits  in Piedra Alta, Lanzarote, belonging to the Marine Isotope Stage 11 dated to circa 330 ka. 4 species of fossil brachiopods have been identificated: Terebratula sinuous Brocchi 1814, Lacazella mediterranea Risso 1826 Terebratulina caputserpentis (Zbyszewski, 1957) and Thecidium cf . digitatum (Sowerby 1823). These fossils provides stratigraphic and paleoclimatic taxonomic information. Furthermore, in order to compare the fossil brachiopods with present in the Canary Island, a reference collection is defined with specimens obtained from marine sediment surveys at Gran Canaria, La Palma and El Hierro, identifying 3 species: Argyrotheca barrettiatia (Davidson, 1866), Megerlia truncata (Linaeus 1767 ) and Pajaudina atlantica (Logan 1988).

Eduardo Zamacois: attività editoriale e opera letteraria

Eduardo Zamacois (Pinar del Río, 1873- Buenos Aires, 1971) was a main actor of the spanish’s literature and edition movement from the first third of the 20th century. He was the founder of magazines that had a big impact like “Germinal”, introductive of the sicalipsis (“La Vida Galante”) or so innovative that deserved an special chapter in the history of literature (“El Cuento Semanal” e “Los Contemporáneos”). With this work, it is intended to recreate the most significant stages from his autobiography adventure including the new information that offers his non before published letters exchange with his last sentimental partner. As a writer, his work was very popular in his homeland, translated to the world and reissued in Ibero-America. His literature work is based in three different phases. He began with the use of gallant literature (with books like La enferma, Punto negro) and took an adventure with the pays of mystery and irony (El otro, El misterio de un hombre pequñito, La opinion ajena) to finally focused in a narrative style of a realistic kind, that includes social critique (Las raíces). His last published novel in Spain is a portrait of Madrid during its long siege by the nationalist troops (El asedio de Madrid), a profound tribute to the people’s heroism and a declaration of love to the capital, that was his place of residence for a long time. While his exile, that took him to Cuba, New York and Buenos Aires, he worked in the radio, the dubbing industry and in finishing his most detailed bibliography, Un hombre que se va, a valuable document of that time.

Effects of Paramuricea clavata (Risso, 1826) (Anthozoa: Plexauridae) forests on settlement of benthic species: an experimental approach

Rationale: Coralligenous habitat is considered the second most important subtidal “hot spot” of species diversity in the Mediterranean Sea after the Posidonia oceanica meadows. It can be defined as a typical Mediterranean biogenic hard bottom, mainly produced by the accumulation of calcareous encrusting algae that, together with other builder organisms, form a multidimensional framework with a high micro-spatial variability. The development of this habitat depends on physical factors (i.e. light, hydrodynamism, nutrients, etc.), but also biologic interactions can play a relevant role in structuring the benthic assemblages. This great environmental heterogeneity allows several different assemblages to coexist in a reduced space. One of the most beautiful is that characterised by the Mediterranean gorgonian Paramuricea clavata (Risso, 1826) that can contribute to above 40% of total biomass of the community and brings significant structural complexity into the coralligenous habitat. In sites moderately exposed to waves and currents, P. clavata can form high-density populations (up to 60 colonies m-2) between 20 – 70 m in depth. Being a suspension feeder, where it forms dense populations, P. clavata plays a significant role in transferring energy from planktonic to benthic system. The effects of the branched colonies of P. clavata could be comparable to those of the forests on land. They can affect the micro scale hydrodynamism and light, promoting or inhibiting the growth of other species. Unfortunately, gorgonians are threatened by several anthropogenic disturbance factors (i.e. fishing, pollution, tourism) and by climatic anomalies, linked to the global changes, that are responsible of thermal stress, development of mucilage and enhanced pathogens activity, leading to mass mortality events in last decades. Till now, the possible effects of gorgonian forest loss are largely unknown. Our goal was to analyse the ecological role of these sea fan forests on the coralligenous benthic assemblages. Experimental setup and main results: The influence of P. clavata in the settlement and recruitment of epibenthic organisms was analysed by a field experiment carried out in two randomly selected places: Tavolara island and Portofino promontory. The experiment consisted in recreate the presence and absence of the gorgonian forest on recruitment panels, arranged in four plots per type (forested and non-forested), interspersed each other, and deployed at the same depth. On every forested panel 3 gorgonian colonies about 20 cm height were grafted with the use of Eppendorf tubes and epoxy resin bicomponent simulating a density of 190 sea fans per m-2. This density corresponds to a mean biomass of 825 g DW m-2,3 which is of the same order of magnitude of the natural high-density populations. After about 4 months, the panels were collected and analysed in laboratory in order to estimate the percent cover of all the species that have colonized the substrata. The gorgonian forest effects were tested by multivariate and univariate permutational analyses of the variance (PERMANOVA). Recruited assemblages largely differed between the two study sites, probably due to different environmental conditions including water quality and turbidity. On overall, the presence of P. clavata reduced the settlement and recruitment of several algae: the shadow caused by the gorgonian might reduce light availability and therefore their growth. This effect might be greater in places where the waters are on average more clear, since at Portofino it is less visible and could be masked by the high turbidity of the water. The same pattern was registered for forams, more abundant outside gorgonian forest, probably linked with algal distribution, shadowing effect or alimentary competition. The last one hypothesis could be valid also for serpulids polychaetes that growth mainly on non-forested panels. An opposite trend, was showed by a species of bryozoan and by an hydroid that is facilitated by the presence of P. clavata, probably because it attenuates irradiance level and hydrodynamism. Species diversity was significantly reduced by the presence of P. clavata forests at both sites. This seems in contrast with what we expected, but the result may be influenced by the large algal component on non-forested panels. The analysis confirmed the presence of differences in the species diversity among plots and between sites respectively due to natural high variability of the coralligenous system and to different local environment conditions. The reduction of species diversity due to the presence of gorgonians appeared related to a worst evenness rather than to less species richness. With our experiment it is demonstrated that the presence of P. clavata forests can significantly alter local coralligenous assemblages patterns, promoting or inhibiting the recruitment of some species, modifying trophic relationships and adding heterogeneity and complexity to the habitat. Moreover, P. clavata could have a stabilising effect on the coralligenous assemblages.

Gewitter und Gewitterschäden im südlichen hessischen Berg- und Beckenland und im Rhein-Main-Tiefland 1881 bis 1980

Basierend auf schriftlichen Quellen, hauptsächlich von 1881-1980 (ohne 1941-50), werden die raum-zeitlichen Eigenschaften von Gewittern mit Schäden im südlichen hessischen Berg- und Beckenland und im Rhein-Main-Tiefland (= UG) herausgestellt. Nach Auswertung des Materials in einer Datenbank erfolgt die Intensitätskategorisierung der Schadensvorgänge für gewitterbedingte Starkregen erstmals anhand der Ähnlichkeitsmerkmale von Folgeerscheinungen, für Blitzschlag erstmals nach Schadensaspekten sowie für Hagelschlag und Sturm mittels existierender und modifizierter Klassifizierungen. Diese Kategorisierungen können für alle Beschreibungen von Gewitterschadensereignissen in schriftlichen Quellen angewandt werden. Die einzelnen Phänomene zeigen deutlich voneinander abweichende Eigenschaften. So treten z.B. Starkregenschäden verstärkt im Frühsommer auf, Sturmschäden überwiegend erst im Hoch- und Spätsommer. Generell lassen sich zwei Jahresmaxima in der Gewitterschadenstätigkeit nachweisen (erste Junidekade, zweite Julihälfte). Schwergewitter mit Sturm (auch Hagel) aus SW-W verursachen überwiegend Schäden im südlichen und westlichen UG, aus W-N meist im nördlichen und östlichen UG. Gewitter mit Starkregenschäden dominieren im östlichen UG. Nach der hier vorgestellten Methode der Schadensschwerpunkte können für Schwergewitter aus dem westlichen Sektor (SW-W, W-N) Schwerpunktzugbahnen im UG gedeutet werden. Es wird die Möglichkeit aufgezeigt, die Schadensdatenauswertung auf historische Szenarien zu übertragen. Für Interpretation und Rekonstruktion dieser für die Belange der Historischen Klimatologie wichtigen Vorgänge wird Datenmaterial aus dem zurückreichenden Zeitraum bis 1700 verwendet.

Effect of Paramuricea clavata (Risso, 1826) "forest" on the benthic populations of Tremiti Islands Effetto "foresta" di Paramuricea clavata (Risso, 1826) sui popolamenti bentonici delle Isole Tremiti

Mediterranean coralligenous habitats are biogenic reefs characterised by high species diversity and built mainly by encrusting calcareous red algae, growing in dim light conditions. The global climate change and several human activities may threaten species living in these habitats, especially some of those that are considered particularly relevant in structuring and in maintaining the complexity and diversity of the benthic assemblages. Among them, the red gorgonian, Paramuricea clavata (Risso, 1826), which can form dense populations, in the last decades showed worrying mass mortality events. Understand the role of this “animal forests” in the coralligenous assemblages is of fundamental importance in order to design appropriate monitoring programs and conservation policies, especially in the marine protected areas. For this purpose, benthic assemblages were studied in presence and absence of red gorgonians at two sites at the Tremiti islands. Overall, the benthic assemblages significantly differed among sites, nevertheless in both places, clear differences between assemblages associated and not associated to the gorgonian forests were found. In particular, encrusting corallinered algae were significantly more abundant in the gorgonian understories at both sites. This result indicates that the gorgonians may promote the development of calcareous algae, which are the main builders of the coralligenous habitats. Moreover species diversity resulted higher in the assemblages associated to the gorgonians. The present study highlights the role of Paramuricea clavata as a relevant ecosystem engineer in the coralligenous habitats.

Ruolo della gorgonia Paramuricea clavata (Risso 1826) nei popolamenti epibentonici coralligeni dell'Isola d'Elba

The red gorgonian Paramuricea clavata is considered a key species in Mediterranean coralligenous habitats and, when present at high density, its colonies may develop “gorgonian forests”, which are three-dimensional structures that increase habitat complexity. Mediterranean coralligenous habitats support high biodiversity but the structure and heterogeneity of communities can be strongly modified by several kinds of human-derived impacts. The global environmental change and human activity could threaten the coralligenous habitats and during the last few decades, Mediterranean suspension feeders have been involved in mass mortality events, in which P. clavata was one of the most affected. Without the complex three-dimensional structures formed by P. clavata, many benthic species may have not adequate sheltering and feeding opportunities. The aim of the present study was to investigate the ecological role of Paramuricea clavata in coralligenous habitats by comparing epibenthic assemblages established inside and outside gorgonian forests. This study was carried out in four sites randomly chosen, along the south-east coast of Elba island (north-western Mediterranean). The structure of the epibenthic assemblages were significantly different between area with and without gorgonians. Main differences concern very important taxa in the coralligenous bioconstruction processes like the encrusting red algae, Peyssonnelia spp. and Halimeda tuna, which were more abundant in presence of gorgonians. On the contrary, algal turf, mucilaginous algae and the invasive seaweed Caulerpa cylindracea were more abundant in areas without P. clavata. The presence of gorgonians may have a positive effect also on species diversity. The results of this study highlight the ecological role of P. clavata in the coralligenous habitats.
