De um falsário a outro, de patranhas viageiras a legados críveis (século XV)

In the 15th and early 16th centuries, when traveling eastward and westward no longer proved extraordinary, travel writings, such as those of Marco Polo or Jean de Mandeville, were printed and reprinted and have been in the world of exchanges and acquisitions both in Portugal and in other parts of Europe. However, although they have played a key role in defining foreign worlds for Europe, reflecting the aspirations of their time and providing news about the universe to be discovered, these reports do not always necessarily tell of trips that were actually taken. Several of them, on the contrary, do no more than draw together, for contemporary readers, passages of interest taken from other writings; passages which, based on their regularity and frequency, would allow for a narrative staged as travel to be taken as truth for contemporaries and immediate successors. In the Iberian Peninsula of the late 15th century, an account written by an author about whom nothing is known, Gomez de Santisteban, who defines himself as a companion of Prince Pedro on a supposed trip to the Holy Land, was among those reports integrated into the description and the perception of the land being discovered. The driving question of this paper is, therefore, how Santisteban, though he wrote memories of trips that he did not take, achieved credibility like those travelers whose trips have been recognized as authentic.

Mode B ultrasonography and abdominal Doppler in crab-eating-foxes (Cerdocyon thous)

Annually hundreds of crab-eating foxes (Cerdocyon thous) are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous) using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12 +/- 0.01 mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1: 1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39 +/- 0.05 mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34 +/- 0.03 mm and three defined layers with hyperechogenic (submucosa and serosa) and hypoechogenic (muscular) features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2 mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60 +/- 0.32 cm/s; EDV: 6.96 +/- 1.68cm/s; PI: 1.15 +/- 0.07 e RI: 0.73 +/- 0.07) and right (PSV: 23.08 +/- 3.34cm/s; EDV: 9.33 +/- 2.36cm/s; PI: 1.01 +/- 0.65 e RI: 0.65 +/- 0.16) and left renal arteries (PSV: 23.74 +/- 3.94cm/s; EDV: 9.07 +/- 3.02cm/s; PI: 1.04 +/- 0.31 e RI: 0.64 +/- 0.10) were determined. Thus, conventional and Doppler ultrasonographic imaging provides basic information that can be used as reference for the species as well for other wild canids and it is a precise and non-invasive method that can be safely used to evaluate and diagnose abdominal injuries in these patients.

Hydrogeologic Setting and Ground-Water Flow Simulations of the Eastern High Plains Regional Study Area, Nebraska

The transport of anthropogenic and natural contaminants to public-supply wells was evaluated in a part of the High Plains aquifer near York, Nebraska, as part of the U.S. Geological Survey National Water-Quality Assessment Program. The aquifer in the Eastern High Plains regional study area is composed of Quaternary alluvial deposits typical of the High Plains aquifer in eastern Nebraska and Kansas, is an important water source for agricultural irrigation and public water supply, and is susceptible and vulnerable to contamination. A six-layer, steady-state ground-water flow model of the High Plains aquifer near York, Nebraska, was constructed and calibrated to average conditions for the time period from 1997 to 2001. The calibrated model and advective particle-tracking simulations were used to compute areas contributing recharge and travel times from recharge areas to selected public-supply wells. Model results indicate recharge from agricultural irrigation return flow and precipitation (about 89 percent of inflow) provides most of the ground-water inflow, whereas the majority of ground-water discharge is to pumping wells (about 78 percent of outflow). Particle-tracking results indicate areas contributing recharge to public-supply wells extend northwest because of the natural ground-water gradient from the northwest to the southeast across the study area. Particle-tracking simulations indicate most ground-water travel times from areas contributing recharge range from 20 to more than 100 years but that some ground water, especially that in the lower confined unit, originates at the upgradient model boundary instead of at the water table in the study area and has travel times of thousands of years.

A lectotype is designated for Parandra janus Bates, 1875. Komiyandra janus (Bates, 1875) is excluded from nearly all previously reported locations, even one location given in the original description, and is now only known from Sulawesi. A paralectotype of Parandra janus Bates, 1875, is designated as a paratype for Komiyandra menieri, new species. Komiyandra formosana is excluded from the Japanese (Ryukyu Is.) fauna. Parandra vitiensis Nonfried, 1894, is again placed in synonymy with P. striatifrons Fairmaire (now Melanesiandra striatifrons). A neotype is designated for Parandra austrocaledonica Montrouzier, 1861. A lectotype is designated for Parandra janus Bates, 1875. The lectotype of Parandra gabonica Thomson, 1858, designated by Quentin and Villiers (1975) is considered invalid. Papuandra araucariae (Gressitt, 1959) is excluded from the fauna of Norfolk Island. The African species Stenandra kolbei (Lameere, 1903) is reported for the first time from Asia (N. Vietnam). Keys are presented to separate worldwide genera of Parandrini and all species within the study regions. Illustrations are provided for all species including many special characters to differentiate genera and species.

The Economics of Threatened Species Conservation: A Review and Analysis

Stabilizing human population size and reducing human-caused impacts on the environment are keys to conserving threatened species (TS). Earth's human population is ~ 7 billion and increasing by ~ 76 million per year. This equates to a human birth-death ratio of 2.35 annually. The 2007 Red List prepared by the International Union for Conservation of Nature and Natural Resources (IUCN) categorized 16,306 species of vertebrates, invertebrates, plants, and other organisms (e.g., lichens, algae) as TS. This is ~ 1 percent of the 1,589,161 species described by IUCN or ~ 0.0033 percent of the believed 5,000,000 total species. Of the IUCN’s described species, vertebrates comprised relatively the most TS listings within respective taxonomic categories (5,742 of 59,811), while invertebrates (2,108 of 1,203,175), plants (8,447 of 297,326), and other species (9 of 28,849) accounted for minor class percentages. Conservation economics comprises microeconomic and macroeconomic principles involving interactions among ecological, environmental, and natural resource economics. A sustainable-growth (steady-state) economy has been posited as instrumental to preserving biological diversity and slowing extinctions in the wild, but few nations endorse this approach. Expanding growth principles characterize most nations' economic policies. To date, statutory fine, captive breeding cost, contingent valuation analysis, hedonic pricing, and travel cost methods are used to value TS in economic research and models. Improved valuation methods of TS are needed for benefit-cost analysis (BCA) of conservation plans. This Chapter provides a review and analysis of: (1) the IUCN status of species, (2) economic principles inherent to sustainable versus growth economies, and (3) methodological issues which hinder effective BCAs of TS conservation.

Revision of the Neotropical robber fly genus Cnodalomyia Hull (Diptera, Asilidae, Asilinae) with description of two new species from Brazil

The genus Cnodalomyia includes only two Brazilian species: C. obtusa Hull, 1962 and C. catarinensis Lamas and Mellinger, 2008. Studying material deposited in the Museu de Zoologia da Universidade de Sao Paulo (MZUSP), the authors found a long series of unidentified specimens of the genus, some of which are specimens of C. obtusa labelled with the same data as the type series as well as other specimens from different localities, representing an enlargement of the known geographic records of the species. This material, together with the types of C. catarinensis, enables this revision. A redescription of the genus and of its type species, C. obtusa, including descriptions and illustrations of its spermathecae and egg, until now never described, the description and illustration of two new species (C. artigasi sp. nov. and C. papaveroi sp. nov.), the diagnosis and egg description of C. catarinensis and an identification key to all included species are presented herein.

Fuzzy Connectedness Image Segmentation in Graph Cut Formulation: A Linear-Time Algorithm and a Comparative Analysis

A deep theoretical analysis of the graph cut image segmentation framework presented in this paper simultaneously translates into important contributions in several directions. The most important practical contribution of this work is a full theoretical description, and implementation, of a novel powerful segmentation algorithm, GC(max). The output of GC(max) coincides with a version of a segmentation algorithm known as Iterative Relative Fuzzy Connectedness, IRFC. However, GC(max) is considerably faster than the classic IRFC algorithm, which we prove theoretically and show experimentally. Specifically, we prove that, in the worst case scenario, the GC(max) algorithm runs in linear time with respect to the variable M=|C|+|Z|, where |C| is the image scene size and |Z| is the size of the allowable range, Z, of the associated weight/affinity function. For most implementations, Z is identical to the set of allowable image intensity values, and its size can be treated as small with respect to |C|, meaning that O(M)=O(|C|). In such a situation, GC(max) runs in linear time with respect to the image size |C|. We show that the output of GC(max) constitutes a solution of a graph cut energy minimization problem, in which the energy is defined as the a"" (a) norm ayenF (P) ayen(a) of the map F (P) that associates, with every element e from the boundary of an object P, its weight w(e). This formulation brings IRFC algorithms to the realm of the graph cut energy minimizers, with energy functions ayenF (P) ayen (q) for qa[1,a]. Of these, the best known minimization problem is for the energy ayenF (P) ayen(1), which is solved by the classic min-cut/max-flow algorithm, referred to often as the Graph Cut algorithm. We notice that a minimization problem for ayenF (P) ayen (q) , qa[1,a), is identical to that for ayenF (P) ayen(1), when the original weight function w is replaced by w (q) . Thus, any algorithm GC(sum) solving the ayenF (P) ayen(1) minimization problem, solves also one for ayenF (P) ayen (q) with qa[1,a), so just two algorithms, GC(sum) and GC(max), are enough to solve all ayenF (P) ayen (q) -minimization problems. We also show that, for any fixed weight assignment, the solutions of the ayenF (P) ayen (q) -minimization problems converge to a solution of the ayenF (P) ayen(a)-minimization problem (ayenF (P) ayen(a)=lim (q -> a)ayenF (P) ayen (q) is not enough to deduce that). An experimental comparison of the performance of GC(max) and GC(sum) algorithms is included. This concentrates on comparing the actual (as opposed to provable worst scenario) algorithms' running time, as well as the influence of the choice of the seeds on the output.

Isolation and characterisation of aerobic endospore forming Bacilli from sugarcane rhizosphere for the selection of strains with agriculture potentialities

Eighteen aerobic endospore forming strains were isolated from sugarcane rhizosphere in N-free medium. A phenotypic description and analysis of the 5' end hypervariable region sequences of 16S rRNA revealed a high diversity of Bacillus and related genera. Isolates were identified, and four genera were obtained: seven strains belonged to Bacillus (Bacillaceae family), four belonged to Paenibacillus, six belonged to Brevibacillus and one strain was identified as Cohnella (Paenibacillaceae family). Four Brevibacillus strains showed in vitro inhibitory activity against plant pathogens fungi Curvularia and Fusarium. Seventy-four percent of the isolated bacteria grew on pectin as the only carbon source, showing polygalacturonase activity. Pectate lyase activity was detected for the first time in a Brevibacillus genus strain. All isolates showed endoglucanase activity. Calcium phosphate solubilisation was positive in 83.3% of the isolates, with higher values than those reported for Bacillus inorganic phosphate solubilising strains. High ethylene plant hormone secretion in the culture medium was detected in 22% of the bacteria. This is the first report of ethylene secretion in Paenibacillaceae isolates. Indole-3-acetic acid production was found in a Brevibacillus genus isolate. It was reported for the first time the presence of Cohnella genus strain on sugarcane rhizosphere bearing plant growth promoting traits. The sugarcane isolate Brevibacillus B65 was identified as a plant growth inoculant because it showed wider spectra of plant stimulation capabilities, including an antifungal effect, extracellular hydrolases secretion, inorganic phosphate solubilisation and plant hormone liberation. In this work, sugarcane was shown to be a suitable niche for finding aerobic endospore forming 'Bacilli' with agriculture biotechnological purposes.

Leaf level VOC emissions of single plants from Amazonian and Mediterranean ecosystems: Ontogeny and flooding as stress factor for VOC emissions

Die Vegetation ist die wichtigste Quelle von organischen flüchtigen Verbindungen (auf Englisch volatile organic compounds,VOCs), die einen bemerkenswerten Einfluss auf der Chemie und Physik der Atmosphäre haben. VOCs beeinflussen die oxidative Kapazität der Atmosphäre und tragen zu der Bildung und zum Wachstum von sekundären organischen Aerosolen bei, welche einerseits eine Streuung und Reflektierung der Energie verursachen und andererseits sich an der Bildung und Entwicklung von Wolken beteiligen. Ziel dieser Arbeit war die Beschreibung und der Vergleich von VOC Emissionen aus Pflanzen aus zwei verschiedenen Ökosystemen: Mediterranes Ökosystem und Tropisches Ökosystem. Für diese Aufgabe wurden gewöhnliche Pflanzen von beiden Ökosystemen untersucht. Siebzehn Pflanzenspezies aus der Mittelmeergebiet, welches bekannt ist für seine Vielfalt an VOC emittierenden Pflanzen, wurden in die Untersuchungen einbezogen. Im Gegensatz zum mediterranen Ökosystem sind nur wenig Information verfügbar über VOC Emissionen aus Blättern tropischer Baumspezies. Vor diesem Hintergrund wurden sechsundzwanzig Baumspezies aus verschiedenen Ökotypen des Amazonasbeckens (Terra firme, Várzea und Igapó) wurden auf VOC Emissionen auf Blattebene mit einem Küvetten-System untersucht. Analysen von flüchtigen organischen Verbindungen wurden online mit PTR-MS und offline mittels Sammlung auf entsprechenden Adsorbern (Kartuschen) und nachfolgender GC-FID Analyse untersucht. Die höchsten Emissionen wurden für Isoprene beobachtete, gefolgt durch Monoterpene, Methanol und Aceton. Die meisten Mittelmeer Spezies emittierten eine hohe Vielfalt an Monoterpenspezies, hingegen zeigten nur fünf tropische Pflanzenspezies eine Monoterpene mit einen sehr konservativen Emissionsprofil (α-Pinen>Limonen>Sabinen >ß-Pinen). Mittelmeerpflanzen zeigten zusätzlich Emissionen von Sesquiterpenen, während bei der Pflanzen des Amazonas Beckens keine Sesquiterpenemissionen gefunden wurden. Dieser letzte Befund könnte aber auch durch eine niedrigere Sensitivität des Messsystems während der Arbeiten im Amazonasgebiet erklärt werden. Zusätzlich zu den Isoprenoidemissionen waren Methanolemissionen als Indikator für Wachtumsvorgänge sehr verbreitet in den meisten Pflanzenspezies aus tropischen und mediterranen Gebieten. Einige Pflanzenspezies beider Ökosystemen zeigten Acetonemissionen. rnrnVOC Emissionen werde durch eine große Vielfalt an biotischen und abiotischen Faktoren wie Lichtintensität, Temperatur, CO2 und Trockenheit beeinflusst. Ein anderer, öfter übersehener Faktor, der aber sehr wichtig ist für das Amazonas Becken, ist die regelmäßige Überflutung. In dieser Untersuchung wir fanden heraus, dass am Anfang einer Wurzelanoxie, die durch die Überflutung verursacht wurde, Ethanol und Acetaldehyd emittiert werden können, vor allem in Pflanzenspezies, die schlechter an eine unzureichende Sauerstoffversorgung bei Flutung adaptiert sind, wie z.B. Vatairea guianensis. Die Spezies Hevea spruceana, welche besser an Überflutung adaptiert ist, könnte möglicherweise der gebildete Ethanol sofort remetabolisieren ohne es zu emittieren. Nach einer langen Periode einer Überflutung konnte allerdings keine Emission mehr beobachtet werden, was auf eine vollständige Adaptation mit zunehmender Dauer schließen lässt. Als Reaktion auf den ausgelösten Stress können Isoprenoidemissionen ebenfalls kurzfristig nach einigen Tage an Überflutung zunehmen, fallen dann aber dann nach einer langen Periode zusammen mit der Photosynthese, Transpiration und stomatäre Leitfähigkeit deutlich ab.rnrnPflanzen Ontogenese ist anscheinend von Bedeutung für die Qualität und Quantität von VOC Emissionen. Aus diesem Grund wurden junge und erwachsene Blätter einiger gut charakterisierten Pflanzen Spezies aus dem Mittelmeerraum auf VOC Emissionen untersucht. Standard Emissionsfaktoren von Isopren waren niedriger in jungen Blättern als in erwachsene Blätter. Hingegen wurden höhere Monoterpen- und Sesquiterpenemissionen in jungen Blätter einiger Pflanzenspezies gefunden. Dieser Befund deutet auf eine potentielle Rolle dieser VOCs als Abwehrkomponenten gegen Pflanzenfresser oder Pathogene bei jungen Blätter hin. In einigen Fällen variierte auch die Zusammensetzung der Monoterpen- und Sesquiterpenspezies bei jungen und erwachsenen Blättern. Methanolemissionen waren, wie erwartet, höher in jungen Blättern als in ausgewachsenen Blättern, was mit der Demethylierung von Pectin bei der Zellwandreifung erklärt werden kann. Diese Befunde zu Änderungen der Emissionskapazität der Vegetation können für zukünftige Modellierungen herangezogen werden. rn

Mesozoic fold structure of the Otago and Alpine Schist Belt and its implications on the tectonic evolution of South Island, New Zealand

Erneute Untersuchungen der mesozoischen Faltenstruktur des Otago Schiefergürtels, Südinsel, Neuseeland, zeigen, dass diese aus zwei aufeinander folgenden, ähnlichen, asymmetrischen, offenen bis mäßig engen Großfaltengenerationen im km- Größenbereich besteht anstatt aus den vorher angenommenen Decken- oder Halbfalten. Hauptproblem der Großfaltenstruktur sind Zonen von durchgreifender Boudinage, die in der Nähe der Großfaltenscharniere entstanden sind. Vorherige Bearbeiter deuteten diese Zonen als 'starke Verformungszonen' oder Überschiebungszonen. Diese Arbeit zeigt, dass in diesen Zonen nur durch die asymmetrische Faltung die unteren liegenden Schenkel der Großfalten boudiniert und somit häufig die ansonsten typischen Faltenstrukturen des liegenden Schenkels einer symmetrischen Faltung überprägt wurden. Ein weiteres Problem dieser mesozoischen Großfaltenstruktur ist die Überprägung einer Faltengeneration auf eine frühere. Weil die Verkürzungsrichtung der überprägenden Faltengeneration nicht subparallel zur älteren Faltenachse ist, sondern einen Winkel von rund 30 Grad einschließt, ist ein Wechsel von orthogonalen zu koaxialen Interferenzmustern der Kleinfalten beobachtbar. Folglich ist die Orientierung der Scheitellinie einer überprägenden und überprägten Kleinfalte nicht unbedingt subparallel zur Orientierung der Faltenachse der Großfalte trotz zylindrischer Faltung. Im letzten Teil dieser Arbeit wird die Überprägung der mesozoischen Großfaltenstruktur durch das känozoisch entstandene, transpressionale Alpine Störungssystem, das einen zweiseitigen Falten- und Überschiebungsgürtel im Otago und im Nordwesten anschließenden Alpinen Schiefergürtel bildet, beschrieben.

Sustainable development in Darjeeling Hills, India : ecological and socio-economic aspects for small-scale farmers with supportive observations from Kanagawa, Japan

Organic farming means a holistic application of agricultural land-use, hence, this study aimed to assess ecological and socio-economic aspects that show benefits of the strategy and achievements of organic farming in comparison to conventional farming in Darjeeling District, State of West Bengal, India and Kanagawa Prefecture/Kanto in Central Japan. The objective of this study has been empirically analysed on aspects of crop diversity, yield, income and sales prices in the two study regions, where 50 households each, i.e. in total 100 households were interviewed at farm-level. Therefore, the small sample size does not necessarily reflect the broad-scale of the use and benefit of organic farming in both regions. The problems faced in mountainous regions in terms of agriculture and livelihoods for small-scale farmers, which are most affected and dependant on their immediate environment, such as low yields, income and illegal felling leading to soil erosion and landslides, are analyzed. Furthermore, factors such as climate, soils, vegetation and relief equally play an important role for these farmers, in terms of land-use. To supplement and improve the income of farmers, local NGOs have introduced organic farming and high value organic cash crops such as ginger, tea, orange and cardamom and small income generating means (floriculture, apiary etc.). For non-certified and certified organic products the volume is given for India, while for Japan only certified organic production figures are given, as there are several definitions for organic in Japan. Hence, prior to the implementation of organic laws and standards, even reduced chemical input was sold as non-certified organic. Furthermore, the distribution and certification system of both countries are explained in detail, including interviews with distribution companies and cooperatives. Supportive observations from Kanagawa Prefecture and the Kanto region are helpful and practical suggestions for organic farmers in Darjeeling District. Most of these are simple and applicable soil management measures, natural insect repelling applications and describe the direct marketing system practiced in Japan. The former two include compost, intercropping, Effective Microorganisms (EM), clover, rice husk charcoal and wood vinegar. More supportive observations have been made at organic and biodynamic tea estates in Darjeeling District, which use citronella, neem, marigold, leguminous and soil binding plants for soil management and natural insect control. Due to the close ties between farmers and consumers in Japan, certification is often neither necessary nor wanted by the producers. They have built a confidence relationship with their customers; thus, such measures are simply not required. Another option is group certification, instead of the expensive individual certification. The former aims at lower costs for farmers who have formed a cooperative or a farmers' group. Consumer awareness for organic goods is another crucial aspect to help improve the situation of organic farmers. Awareness is slightly more advanced in Kanto than in Darjeeling District, as it is improved due to the close (sales) ties between farmers and consumers in Kanto. Interviews conducted with several such cooperatives and companies underline the positive system of TEIKEI. The introduction of organic farming in the study regions has shown positive effects for those involved, even though it still in its beginning stages in Darjeeling District. This study was only partly able to assess the benefits of organic agriculture at its present level for Darjeeling District, while more positively for the organic farmers of Kanto. The organic farming practice needs further improvement, encouragement and monitoring for the Darjeeling District farmers by locals, consumers, NGOs and politicians. The supportive observations from Kanagawa Prefecture and the Kanto region are a small step in this direction, showing how, simple soil improvements and thus, yield and income increases, as well as direct sales options can enhance the livelihood of organic farmers without destroying their environment and natural resources.
