O gênero Polytrichastrum (Polytrichaceae) está distribuído em ambos hemisférios e é composto por quatorze espécies, dentre elas Polytrichastrum alpinum (Hedw.) G.L. Esta planta apresenta gametófito robusto, podendo ser simples ou ligeiramente ramificado e na região do limbo do filídeo são encontradas lamelas, estas taxonomicamente importantes para a identificação da espécie e diferenciação das demais plantas do gênero e da família. Segundo a literatura, esta espécie possui distribuição bipolar intermediária, ocorrendo nas regiões polares e em regiões tropicais de altas altitudes. O objetivo deste estudo foi investigar com mais profundidade a morfologia de espécimes de P. alpinum oriundos dos hemisférios Norte e Sul, a fim de verificar o status de bipolaridade proposto. Para isso foram utilizadas ferramentas morfológicas: Microscopia Eletrônica de Varredura (MEV) e anatomia, além de observados os caracteres taxonômicos que definem esta espécie. Através das ferramentas morfológicas citadas foram comparadas amostras advindas de ambas regiões polares e foram encontradas pequenas diferenças morfológicas entre os espécimes que ocorrem na Antártica quando comparados aos do hemisfério Norte. No entanto, estas diferenças podem ocorrer por serem ambientes diferentes e estas podem ser adaptações desta planta às condições extremas que são encontradas na Antártica. _______________________________________________________________________________________________ ABSTRACT
The genus Polytrichastrum (Polytrichaceae) is distributed in both hemispheres and consists of fourteen species, among them Polytrichastrum alpinum (Hedw.) GL. This plant has robust gametophyte and can be simple or slightly branched and lamellae are found in leaf limb region, these taxonomically important for species identification and differentiation from other plants of the genus and family. According to the literature, this species have intermediate bipolar distribution, occurring in the polar regions and in tropical regions of high altitudes. The objective of this study was to investigate in more depth the morphology of P. alpinum specimens coming from the northern and southern hemispheres, in order to check the status of proposed bipolarity. We used morphological tools: scanning electron microscopy (SEM) and anatomy, as well as observing the taxonomic characters that define this species. Through the aforementioned morphological tools samples were compared arising from both polar regions and found minor morphological differences between species that occur in Antarctica when compared to the Northern Hemisphere. However, these differences can occur are different environments and they may be adapted to the extreme conditions of the plant that are found in Antarctica.

O corpus constituído para o Atlas Lingüístico do Paraná, embora já tenha sido explorado por inúmeros pesquisadores e acadêmicos (de graduação e pósgraduação) das diversas áreas de estudo da linguagem, não foi totalmente cartografado. As comunicações, artigos, dissertações corroboram a necessidade de sistematização e apresentação, em forma de cartas lingüísticas, dessa parte do corpus ainda inédito. Desta forma, o objetivo geral deste trabalho é cartografar os dados coletados para a pesquisa de Aguilera (1994) não contemplados no Atlas Lingüístico do Paraná, dando, assim, continuidade aos estudos iniciados por essa pesquisadora e possibilitando o acesso à totalidade dos dados coletados. As questões inéditas, 54% do questionário aplicado, são o objeto deste projeto de pesquisa. A exemplo da obra de Aguilera (1994), as cartas apresentam informações semântico-lexicais, fonético-fonológicas e notas das ocorrências únicas para reproduzir as variantes registradas nos 65 pontos de estudo. As transcrições das entrevistas, foram revisadas e armazenadas em MD marca Sony de 74 min. A análise das respostas, feitas através do método dialetométrico, discute, por meio dos Índices Relativos de Distância e Identidade (IRD e IRI, respectivamente), a diversidade lexical apresentada pela localização geográfica e pela colonização local.Even innumerable researchers and academics in several areas of the study of language (graduation and after-graduation) has already explored the data about the corpus of Atlas Linguistic of Paraná, the information collected has not been mapped. The oral presentations, articles, papers corroborate the necessity of systematization and presentation in order to show this unknown corpus, in a linguistic letters form. In this way, the main objective of this paper is to map the data collected by Aguilera (1994) in his research and not contemplated in Atlas Linguistic of Paraná, giving, thus, continuity to the studies initiated by this researcher and making possible the access to the totality of collected data. The unknown questions, 54% of the applied questionnaire, are the object of this project of research. As the example of the Aguilera?s work (1994), the maps presents semantic-lexical information, phonetic-fonologicals and notes of the only occurrences to reproduce the variants registered in the 65 points of study. The transcriptions of the interviews had been revised and stored in Sony MD with 74 minutes each one. The analysis of the answers, made through the dialetometric method using the Relative Indices of Distance and Identity (RID and RII, respectively) argues the lexical diversity presented by the geographic localization and the local settling.

Texto completoResumen
Leontopodium alpinum (Edelweiss, Flor de las nieves, Estrella alpina) es una planta herbácea perenne de la familia de las Asteráceas. Se trata de una especie protegida que en España se localiza en áreas del sistema pirenaico de Aragón y Cataluña, en altitudes entre 1.500 y 2.800 m. La planta de edelweiss tiene un gran atractivo ornamental gracias a su característica flor en forma de estrella. Su carácter emblemático hace que sea una flor muy apreciada, por lo que sus poblaciones se han visto amenazadas por recolecciones indiscriminadas. En la tradición alpina, además se ha venido utilizando como planta medicinal como remedio frente a diversas enfermedades. Los extractos de la planta son, de hecho, una importante fuente de principios activos tales como antioxidantes y otras sustancias con propiedades anti-inflamatorias y citoprotectoras que confieren a edelweiss un gran interés farmacológico y biotecnológico.
Las principales limitaciones para poder comercializar las plantas de edelweiss con un propósito ornamental se encuentran en las necesidades de localización de cultivo en altitudes elevadas de montaña para asegurar la calidad de la flor y en la estacionalidad de la producción. Asimismo, su condición de planta protegida limita la disponibilidad de materiales para la extracción de compuestos fitoquímicos de interés.
En el presente trabajo se han desarrollado dos protocolos de micropropagación de plantas de L. alpinum pertenecientes a la población española de esta especie. En el primero de ellos, se partió de flores maduras aisladas de plantas silvestres recolectadas en campo. Estas flores se implantaron en cultivo in vitro y se indujo, mediante regeneración organogénica indirecta, la formación de brotes adventicios que se incorporaron posteriormente a un proceso de multiplicación y enraizamiento de gran eficiencia. Mediante este protocolo se garantiza la producción de un gran número de plantas clonales que pueden utilizarse con un fin comercial o como material de partida para la extracción y purificación de metabolitos de interés, sin amenazar a las poblaciones naturales. Asimismo, puede plantearse como herramienta complementaria para los proyectos de conservación de esta especie. En el segundo de los protocolos establecidos, se utilizó como material de partida hojas de plantas micropropagadas cultivadas in vitro. Este tipo de explante, cuya utilización no ha sido descrita con anterioridad en edelweiss, mostró una elevada capacidad organogénica en medios de cultivo con tidiazurón (TDZ). A la vista de los resultados, este protocolo proporciona un método de regeneración de plantas in vitro eficaz y reproducible que puede suponer un primer paso para el abordaje de la transformación genética de plantas de L. alpinum
Por otro lado, se ha estudiado la floración de las plantas micropropagadas y cultivadas en condiciones de invernadero a nivel del mar, mediante la aplicación de distintas condiciones de inducción basadas en la temperatura de cultivo, el fotoperíodo y la aplicación exógena de giberelinas. Como resultado de estos estudios se plantea un sistema alternativo de obtención de flores de edelweiss basado en el tratamiento de plantas micropropagadas con giberelinas, que permite la obtención de inflorescencias en invernadero de manera sincronizada y sin restricciones estacionales.Mondéjar Canet, RJ.

Texto completoResumen
Understanding the factors affecting species distribution and at what scale a species respond to these factors is a major challenge in conservation biology. I studied the distribution and abundance of a monophagous shield bug Canthophorus impressus at three spatial scales: host plants, patches and circular landscapes (area ca. 3 km2), to determine the relative importance of the different spatial scales and how habitat quality, amount and spatial configuration affect the distribution of C. impressus. Influence of habitat characteristics on occurrence and abundance of the bug was analysed with separate generalised linear mixed models. The data show that effects of habitat quality and amount dominate over configuration in determining the distribution of C. impressus. The bug prefers large host plants in warm conditions on a plant scale and abundant host plants in a landscape scale, whereas patch scale was not important for the distribution of the bug. Management should aim to preserve sites with abundant host plants and promote large host plants with low to moderate grazing. To secure sufficient number of host plants in the landscape, high densities of suitable habitat such as semi-natural grasslands should be preserved. This study suggests that analyses of multiple spatial scales are crucial for identifying appropriate actions for successful conservation of species living in fragmented habitats.

Texto completoResumen
Nous avons donc focalisé notre travail sur la recherche de substances naturelles antiradicalaires et inhibitrices de la tryptase, deux cibles potentielles pour la prévention du vieillissement et de l’assèchement cutané. Les racines d’Eryngium alpinum L. (Apiaceae, Saniculoideae) possèdent une activité antiradicalaire. Les substances actives isolées sont l’acide chlorogénique, l’acide rosmarinique et un nouveau composé, l’acide R-(+)-3’-O-β-D-glucopyranosyl rosmarinique. Une étude chimiotaxonomique a permis de sélectionner une plante plus riche en composés actifs, la Sanicule (Sanicula europeae L). L’acide R-(+)-3’-O-β-D-glucopyranosyl rosmarinique, détecté uniquement dans les espèces appartenant à la sous-famille des Saniculoideae, peut être utilisé comme marqueur de cette sous-famille. Un criblage de 123 plantes a permis de mettre en évidence l’activité inhibitrice de la tryptase des graines de Sinapis alba L. (Brassicaceae). La substance active isolée est la 4-hydroxybenzylamine (IC50 0,24 mM ; Ki 0,21 mM). Trois substances trois fois plus actives, la 4-hydroxybenzamidine, la benzamidine et la 3-chlorobenzylamine ont été identifiées. Une étude de la sélectivité tryptase vs d’autres sérines protéases de la 4-hydroxybenzylamine et de la 4-hydroxybenzamidine montra que la 4-hydroxybenzylamine inhibe préférentiellement la tryptase. Elle constitue de ce fait un candidat potentiel pour une utilisation en cosmétologieWe focused our work on the search for natural, antiradical, and tryptase-inhibiting substances, two potential targets for preventing accelerated skin aging and drying. The roots of Eryngium alpinum L. (Apiaceae, Saniculoideae) have an antiradical activity. The isolated active substances are chlorogenic acid, rosmarinic acid and a new compound, R-(+)-3’-O-β-D-glucopyranosyl rosmarinic acid. By a chemotaxonomic study, we could select a plant enriched in rosmarinic acid and R-(+)-3’-O-β-D-glucopyranosyl rosmarinic acid : sanicula (Sanicula europeae L). R-(+)-3’-O-β-D-glucopyranosyl rosmarinic acid, only detected in those species belonging to the Saniculoideae subfamily, can be used as a marker of this subfamily. A screening of 123 plants made it possible to show the tryptase-inhibiting activity of Sinapis alba L. (Brassicaceae) seeds. The isolated active compound is 4-hydroxybenzylamine (IC50 0. 24 mM; Ki 0. 21 mM). Three substances three times more active, namely 4-hydroxybenzamidine, benzamidine and 3-chlorobenzylamine were identified. The tryptase selectivity towards other serine proteases of 4-hydroxybenzylamine and 4-hydroxybenzamidine showed that 4-hydroxybenzylamine preferentially inhibits tryptase. This substance thus constitutes a potential candidate for a cosmetic application

Texto completoResumen
The objective of the study was to compare three systems for detection of estrus and combinations of these systems on a large commercial dairy (1000 lactating cows) during stress of summer heat. At 37 to 45 days in milk (DIM), 266 cows were fitted with a HeatWatch (HW) device (HeatWatch; DDx Inc., Boulder, CO), an activity (A) sensor (ALPRO; DeLaval Inc., Kansas City, MO), and observed visually (V) twice daily. Pregnancy status was determined by uterine palpation 35 to 49 d following artificial insemination (AI). The effects of DIM, parity, physical activity, standing events, months, AI technician, and interval between onset of estrus and AI on conception rate were determined using linear contrasts and logistic regression. Efficiencies for detection of estrus, determined by comparing detected periods of estrus with a theoretical total of 707 periods, were 45.8% (V), 33.2% (A), 40.3% (HW), and 71.6% for all three systems simultaneously. Conception rates (LSM ± SE) by method of detection were 16.7 ± 4.9 for HW, 19.8 ± 5.5 for A, 7.9 ± 3.4 for V, 16.3 ± 6.0 for V + A, 27.6 ± 4.6 for V + HW, 21.1 ± 4.9 for A + HW, and 21.9 ± 4.5 for V + A + HW. Conception rate and number of mounts decreased for cows in first versus second and third parity (P < 0.05). For periods of estrus detected by A, the lowest conception rate (P < 0.05) occurred >18 h after the onset of estrus (16.7 ± 7.9). The highest conception rate occurred with the combination of V + HW, which confirms the premise that combination of multiple systems enhances both the efficiency and accuracy of detection.Master of Science

In this work, we make an analysis of the book "Exame de Bombeiros", by José Fernandes Pinto Alpoim (1700-1765). We discuss themes and aspects of both science and mathematics in the analysis of the book. José Fernandes Pinto Alpoim, a Portuguese Military Engineer, was responsible for several works and served in various missions in Brazil, including demarcation of colonial boundaries. He also had relevant contributions for the teaching of mathematics in Brazil. Alpoim wrote two books, the Exame de Artilheiros , in 1744, and the Exame de Bombeiros , in 1748. for use in the course of Artillery and Fortifications in Rio de Janeiro, because there was no suitable material for these courses in Portuguese. About the printing of books, respectively in Lisbon and Madrid, several speculations were raise, which we have discussed in this work. The precarious education in Brazil lead Alpoim to interesting didactic options. We seek to highlight the concern of Alpoim with systematization of Mathematics, always seeking a link between contents and practice. His approach, in the form of questions and answers, shows the concern of the teacher to make meaningful teaching of Mathematics to the students Third of Artillery of Rio de Janeiro, which is the third of a full Regiment. This course was the responsibility of Alpoim

Sobre a impressão dos livros, respectivamente em Lisboa e em Madrid, surgiram várias especulações, que discutimos neste trabalho. A formação escolar precária no Brasil leva Alpoim a interessantes opções de exposição didática. Procuramos destacar a preocupação de Alpoim com a sistematização da Matemática, sempre buscando um elo entre o conteúdo e a prática. Sua abordagem, em forma de perguntas e respostas, mostra a preocupação do professor em tornar significativo o ensino de Matemática aos alunos do Terço de Artilharia do Rio de Janeiro, que é a terça parte de um regimento. Esse curso era a responsabilidade de Alpoim

Texto completoResumen
La conservation d'une espèce nécessite de comprendre les mécanismes évolutifs régissant sa dynamique. L'objectif de cette thèse est de mettre en évidence la complémentarité de différentes approches dans l'étude d'une espèce en danger telle que Eryngium alpinum L. , plante Alpine protégée et à forte valeur patrimoniale. L'espèce est principalement menacée par la fermeture du milieu, limitant l'habitat favorable. Plusieurs thématiques ont été abordées: structure génétique neutre (marqueurs moléculaires) et adaptative (culture en jardin commun), système de reproduction, dynamique des populations, et impact de la déprise agricole (expérimentations in situ). L'étude génétique a été effectuée à différentes échelles: phylogéographie sur l'Europe, relations entre populations françaises, et structure fine au sein d'un vallon de 10 km de long. Les diversités neutre et adaptative sont élevées, indiquant un fort potentiel évolutif des populations. Entre populations, la très forte différenciation neutre suggère la quasi-absence des flux de gènes entre vallées. Au contraire, la différenciation adaptative est très faible, montrant l'action homogénéisante de la sélection entre sites. Au sein d'un vallon, aucune discontinuité génétique n'a été détectée malgré la fragmentation du paysage. Sur des distances plus restreintes, la faible dispersion des graines provoque une structure génétique prononcée. Du fait de la protandrie et d'un système d'autoincompatibilité partielle, l'espèce est très majoritairement allogame. Enfin, le suivi des populations et les expériences sur l'impact de la fermeture du milieu doivent être poursuivies mais l'effet négatif du pâturage printanier et la limitation en pollinisateurs des petites populations sont suggérés. Ces résultats sont discutés dans une perspective de conservation. A court terme, les facteurs écologiques représentent sans doute la menace principale, mais des risques génétiques liés à la fragmentation pourraient se manifester dans le futurKnowledge of the evolutionary mechanisms shaping the dynamics of a species is crucial for its conservation. This work aims to show the complementary nature of several approaches in the study of endangered species such as the protected Alpine plant Eryngium alpinum L. This plant is mainly threatened by land closure that restricts suitable habitat. Different topics have been considered: neutral and adaptive genetic structure (molecular markers and a common garden experiment), breeding system, population dynamics and the impact of land closure (in situ experiments). The genetic study was performed at different scales: phylogeography across Europe, relationships among French populations and fine-scale structure in a 10 km-long valley. Neutral and adaptive diversities were high within populations, suggesting their strong evolutionary potential. Among populations, very strong neutral genetic differentiation is consistent with the absence of gene flow between sites. On the contrary, adaptive differentiation was very low, probably due to the homogenizing effect of selection. Within a valley, no genetic barrier was detected in spite of the observed landscape fragmentation. In restricted areas, low seed dispersal appears to have generated pronounced genetic structure. Because of protandry and partial self-incompatibility, the species is almost completely out-crossing. Finally, population monitoring and experiments on the impact of land closure must be continued to strengthen those results, but the negative impact of grazing (in spring) and the possible effect of pollinator limitation in small populations are suggested. The results are discussed in a conservation perspective. In the short term, ecological factors seem to be the major threats, but genetic risks associated with fragmentation could appear in the future

Texto completoResumen
In recent years wearable devices have been advancing at a rapid pace and one of the largest growing segments is the smart glass segment. In this thesis the feasibility of today’s ARM-based smart glasses are evaluated for automatic license plate recognition (ALPR). The license plate is by far the most prominent visual feature to identify a spe- cific vehicle, and exists on both old and newly produced vehicles. This thesis propose an ALPR system based on a sequence of vertical edge detection, a cascade classifier, verti- cal and horizontal projection as well as a general purpose optical character recognition library. The study further concludes that the optimal input resolution for license plate detection using vertical edges is 640x360 pixels and that the license plate need to be at least 20 pixels high or the characters 15 pixels high in order to successfully segment the plate and recognize each character. The separate stages were successfully implemented into a complete ALPR system that achieved 79.5% success rate while processing roughly 3 frames per second when running on a pair of Google Glass.Under de senaste åren har området wearables avancerat i snabb takt, och ett av de snabbast växande segmenten är smarta glaögon. I denna examensuppsats utvärderas lämpligheten av dagens ARM-baserade smarta glasögon med avseende på automatisk registreringsskyltigenkänning. Registreringsskylten är den i särklass mest framträdande visuella egenskapen som kan användas för att identifiera ett specifikt fordon, och den finns på både gamla och nyproducerade fordon. Detta examensarbete föreslår ett system för automatisk registreringsskyltigenkänning baserat på en följd av vertikal kantdetektering, en kaskad av boostade klassificerare, vertikal och horisontell projektion samt ett optiskt teckenigenkänningsbibliotek. Studien konstaterar vidare att den optimala upplösningen för registreringsskyltdetektion med hjälp av vertikala kanter på smarta glasögonär 640x360 pixlar och att registreringsskylten måste vara minst 20 pixlar hög eller tecknen 15 pixlar höga för att registreringsskylten framgångsrikt skall kunna segmenteras samt tecken identifieras. De separata stegen implementerades framgångsrikt till ett system för automatisk registreringsskyltigenkänning på ett par Google Glass och lyckades känna igen 79,5% av de testade registreringsskyltarna, med en hastighet av ungefär 3 bilder per sekund.

This thesis evaluates the performance of a vehicle detection technology, Automated License Plate Recognition (ALPR) camera systems, with regards to its ability to produce real-time travel time information in active work zones. A literature review was conducted to investigate the ALPR technology as well as to identify other research that has been conducted using ALPR systems to collect travel time information. Next, the ALPR technology was tested in a series of field deployments in both an arterial and a freeway environment. The goal of the arterial field deployment was to evaluate the optimal ALPR camera angles that produce the highest license plate detection rates and accuracy percentages. Next, a series of freeway deployments were conducted on corridors of I-285 in Atlanta, Georgia in order to evaluate the ALPR system in active work zone environments. During the series of I-285 freeway deployments, ALPR data was collected in conjunction with data from Bluetooth and radar technologies, as well as from high definition video cameras. The data collected during the I-285 deployments was analyzed to determine the ALPR vehicle detection rates. Additionally, a script was written to match the ALPR reads across two data collection stations to determine the ALPR travel times through the corridors. The ALPR travel time data was compared with the travel time data produced by the Bluetooth and video cameras with a particular focus on identifying travel time biases associated with each given technology. Finally, based on the knowledge gained, recommendations for larger-scale ALPR work zone deployments as well as suggestions for future research are provided.

Texto completoResumen
I dagsläget överproduceras och överkonsumeras mat, samtidigt slängs 30% av all mat som produceras i världen. Matproduktionen står för en stor del av världens miljöbelastning; främst genom animaliska produkter såsom kött och mejeriprodukter, och därför har ämnet blivit mycket omtalat. I samband med denna debatt har mjölksubstitut introducerats på marknaden. Målet med arbetet var att undersöka hur matbutiker i Stockholm arbetar med svinn och försäljning av mjölk och mjölksubstitut. En jämförelse gjordes mellan Arla Mellanmjölk, Alpro Soya och Alpro Mandeldryck. Datainsamlingsmetoden gjordes dels i kvantitativt format där siffror över försäljning och svinn samlades in, men även i kvalitativt format, i form av intervjuer med sex utvalda matbutiker. Det visade sig att svinnet för Arla Mellanmjölk, Alpro Soya och Alpro Mandeldryck var minimalt med anledning att det alltid finns efterfrågan på dessa produkter och att matbutikerna aktivt arbetar för att hålla svinnet lågt. Detta görs genom att ha ett välkalibrerat automatiskt beställningssystem som tar hand om majoriteten av butikens beställningar in, ha bra kylar i butiken, samt att regelbundet inventera butiken. De produkter som undersöktes ansågs inte behöva exponeras på något speciellt vis då de är basvaror som i princip säljer sig själva. Det är snarare ett problem att mjölksubstituten tar slut från centrallagret emellanåt när efterfrågan blir för stor. Matbutikernas primära mål är att driva ett lönsamt företag och ansträngningarna som görs sker på grund av ekonomiska fördelar. Likväl, även om minskat svinn görs med anledning att inte gå i förlust ekonomiskt blir utfallet detsamma och till fördel för miljön. Konsumenterna verkar tillsynes vara de som har mest makt i att förändra hur matbutikernas verksamhet bedrivs. Genom att välja mjölksubstitut framför mjölk kommer följaktligen miljöbelastningen från mjölkproduktionen att minska.The food production and consumption today are excessive, while 30% of all produced food in the world goes to waste. Food production has a significant effect on the environment; primarily through animalistic products such as meat and dairy food, it is, therefore, a much-disputed subject. Milk alternatives have, as a reaction to this, been introduced on the market. This project aimed to examine how grocery stores in Stockholm handle food waste and sales of milk and milk alternatives. A comparison was made between Arla semi-skimmed milk, Alpro Soya and Alpro Almond. The data collection methods were both quantitively, as numbers of sales and waste were collected, but also qualitative, with interviews with six selected grocery stores. The food waste for Arla semi-skimmed milk, Alpro Soya and Alpro Almond was minimal as a result of constant demand for these products, and also the grocery stores active work to prevent food waste. This is accomplished through a well calibrated automatic ordering system that controls the majority of the store's orders. Additionally, new refrigerators and continuous inventory are also methods used to minimize the food waste. The grocery stores felt no reason to expose the selected products in any particular way since they are already well-known and gets sold without any effort. It is rather an issue that the demand for the milk substitutes is too high and the central warehouse has no supply. The grocery stores' primary goal is to conduct a profitable business, and when the stores put in an effort, the objective is the economic benefits. Nonetheless, even though the reduced food waste is a product of the grocery stores effort to minimize unnecessary economic losses, the outcome will be the same; a benefit for the environment. The consumers seem to have the most influence on how grocery stores conduct their businesses. By choosing a milk substitute over regular milk, the environmental impact from the production of milk will be reduced.

Marty, Charles. "Nutrition et réponses des plantes subalpines pyrénéennes à la contrainte azotée". Toulouse 3, 2009. http://thesesups.ups-tlse.fr/603/.
Texto completoResumen
Les habitats d'altitude sont caractérisés par une faible disponibilité en azote, principal élément limitant la croissance des plantes. Ils offrent par conséquent l'opportunité d'étudier les mécanismes d'utilisation et de conservation de l'azote développés par les plantes, ainsi que l'organisation des communautés végétales en réponse à cette contrainte. Des expériences de traçage isotopique au 15N en chambre de culture font apparaître une faible capacité de prélèvement net de l'azote minéral chez une espèce herbacée caractéristique des milieux montagnards du sud de l'Europe (Festuca nigrescens). Ceci resulte d'un efflux très important (jusqu'à 80% de l'influx pour NH4+), et non d'une faible valeur d'influx. Ce résultat suggère que cette plante ne serait pas capable d'utiliser efficacement un surplus d'azote d'origine anthropique dans son milieu naturel. En serre, d'autres expériences de traçage mettent en évidence un flux d'azote important d'une espèce fixatrice (Trifolium alpinum) vers Festuca eskia (Poaceae). Ce flux est beaucoup plus faible vers Nardus stricta (Poaceae), espèce généralement associée aux deux précédentes dans les pelouses subalpines pyrénéennes. Nos résultats font apparaître un effet facilitateur de la légumineuse sur les deux poacées en milieu naturel: leur croissance et leur prélèvement en azote sont en effet stimulés par sa proximité. Cependant, lorsque les trois espèces sont associées sur le terrain, seule F. Eskia tire bénéfice de la présence de la légumineuse, suggérant que cette espèce est plus compétitive dans l'acquisition de l'azote en provenance de T. Alpinum. Il est souvent considéré que la disponibilité en azote exerce un contrôle sur la durée de vie des feuilles, le recyclage interne de cet élément ou encore la capacité photosynthétique des plantes. .Nitrogen is often assumed to be the most limiting element for plant productivity in most ecosystems, particularly in high altitude habitats where soil nitrogen availability is low. In this thesis, we study both the use and conservation mechanisms of nitrogen that are crucial for plants in these nitrogen-constrained habitats. Moreover we try to understand nitrogen influence on the structure of plant communities. In growth chamber experiments, we investigated the component ?uxes of 15NO3- and 15NH4+ uptake in a tussock grass (Festuca nigrescens) very common and representative of the dominant plant growth form in European alpine meadows. Our results show that mineral nitrogen uptake is very low because of very high nitrogen efflux (up to 80% of the influx for NH4+). It suggests that the ability of this typical alpine grass to respond to increasing nitrogen availability due to global changes is limited. 15N labeling experiments performed in glasshouse show that large 15N transfers occur from a nitrogen-fixer (Trifolium alpinum) to Festuca eskia (Poaceae). This transfer is significantly lower for Nardus stricta, another grass species living in Pyrenean subalpine meadows. In the field, both biomass and nitrogen content of the grasses increase when they are associated to T. Alpinum. However, the facilitation effect between the nitrogen-fixer and non-fixers are species specific and is modified according to the capacity of the receiver species to use nitrogen provided by the legume to the interacting plants. It has often been proposed that nitrogen availability can control leaf life span, nitrogen internal cycling and photosynthetic capacity. .

L'objet de cette these est l'etude des composes fermions lourds supraconducteurs cecu#2si#2 et upd#2al#3 sous pression dans leur phase normale et supraconductrice par resistivite electrique (p#a#c) et par susceptibilite magnetique alternative (#a#c). Les mesures ont ete effectuees en conditions quasi-hydrostatiques (steatite) et hydrostatiques (#4he). Les mesures par resistivite electrique se sont effectuees sous champ magnetique : un diagramme hc#2(t) a ete etabli sous pression pour les deux composes. Pour cecu#2si#2, l'etude sur monocristal en resistivite electrique sous champ magnetique et sous pression (b,t)#- a montre une augmentation drastique du champ critique dans le regime ii avec hc#2(o)5 t contre 2,1 t a pression nulle. Les ajustements du champ critique dans un modele de supraconducteur en limite propre et couplage faible indiquent une anisotropie liee sans doute a la surface de fermi non spherique (coefficient gyromagnetique <1) tandis que ceux en limite sale et couplage fort indiquent une changement de comportement net entre les regimes i et ii. La pente varie fortement sous pression : 25 k/t dans le regime i et 12 k/t dans le regime ii. Pour upd#2al#3, une etude en susceptibilite magnetique sous pression #a#c- sur polycristaux caracterises en transport a permis d'etablir : un diagramme t#c(p) montrant une forte diminution de la supraconductivite apres 6 gpa. On constate en resistivite sous champ et sous pression le maintient du regime de liquide de fermi. On constate peu de variation du champ critique sous pression : la masse effective liee a la pente a t#c presente un faible maximum autour de 5 gpa avant de diminuer fortement a partir de 6 gpa. Ces deux composes presentent deux aspects de l'interaction entre supraconductivite non conventionnelle et magnetisme : competition pour cecu#2si#2 et coexistence pour upd#2al#3.

Texto completoResumen
This thesis will build upon my undergraduate dissertation. It is enriched by the new information about the original historic Beaufort rock garden. It explores the Beaufort rock garden and includes points of view of the experts on its condition today. The following part of the thesis comprises of a proposal for a renewal of the current Bečov botanical garden framework and of a more detailed focus on few selected rocks and their initial planting. The main contribution of this work is an expansion of the total number of the initially grown plants (from 654 to 1228) thanks to the newly found resources and to the writing down all the newly discovered information from the archival research of the original historical documents dated from 1908 to 1937. All the documents were catalogued by the author of the original concept alpina, the head gardener Johann Koditek. What we do know from the original documentation is how the area expanded between the years 1922 - 1927 with the purchase of the surrounding land. It is clear that the expenses for the land were about 18 098,31crowns and for various works, building construction, plants, materials and wages the total sum was 468 336.07 crowns. The exact mounting plans for landscape park were rediscovered (10 plans and inventories in total) and 16 plans and inventories in total of 47 for the rock garden. The chart with the total number of the originally cultivated taxa also consists of the surviving taxa in the area (22 specific herb species + 43 specific tree species and 12 tree genera). The synonymy of the original plants was created for three selected rocks and surveyed their purchase options today. Most of the taxa will return back to the garden, only rock no. 8 will have to be planted differently due to the lack of light on the original plants. Keywords: origin

Texto completoResumen
Environmental conditions can influence epigenetic variability of clonal organisms. These environmentally induced changes have potential to persist in following generations. In theory, this transgenerational memory could allow clonal (and especially apomictic) plants to partly compensate reduced genetic variability and could enhance adaptative ability of apomictic populations. According to Muller's ratchet model, asexual organisms amass deleterious mutations, which could lead to their extinction. Possible transgenerational memory could partly compensate for this. It could also account for longtime survivorship of asexual organisms in environment. This thesis deals with transgenerational memory of triploid apomictic populations of Hieracium alpinum, with completely missing sexuality and thus genetically uniform offspring. Transgenerational effect in Hieracium alpinum was studied on clonal lineages originated from 5 populations (Norway, Austria, Bosnia and Herzegovina and Slovakia). Seeds were planted in cultivation experiment I in 3 treatments (control, added nutrients, added salicylic acid) and vegetative and generative traits were measured. Plants responded to nutrient addition but not to salicylic acid. Treatment with nutrient addition increased biomass, number of leaves and SLA (specific leaf...
