Texte intégralComparative ecology has highlighted recurring associations between plant functional traits and their environment. These relationships may vary depending on the level of organization considered – within species, between species, and among groups of species – but this dependency remains poorly studied. A fundamental distinction in life history theories is made between annual species (completing their life cycle in one year) and perennial species (life cycle over more than one year, usually with multiple reproductive events). Annual and perennial herbaceous plants differ in their functioning (growth rate, investment in seed production, allocation to roots, etc.). However, despite their frequent coexistence, few studies have considered potential differences in trait-environment relationships between these two groups. The objective of this thesis is to understand the specific variations in the traits of annual plants depending on resource availability, based on in situ measurements and in a common garden setting.We studied herbaceous communities in the Grands Causses, where annuals and perennials coexist in two contrasting environmental conditions: i) fertilization and high disturbance, and ii) poor soil and less intense disturbance. We show that variations in traits related to growth rate and leaf tissue density are lower in annuals than in perennials. This is explained by (a) a higher species turnover in perennials, and (b) the presence of species with larger differences in trait values between environments in perennials. Intraspecific variations are identical between the two groups of species. Measurements made during this first part were used to complete a trait database under development. On this occasion, I contributed to the structuring of this database through data management work, aiming to propose modalities for sharing functional trait data and associated environmental variables; a synthesis of this work is proposed.Secondly, we analyzed intraspecific variability in annuals from these communities, in order to test its origin (genetic or plastic), to identify the most variable traits in response to fertilization, and to compare this variability between species. Thirty populations were grown in a common garden, with low or high fertilization. The results indicate that i) the observed trait variations in situ are likely of plastic origin; ii) plasticity is low in morphological leaf and root traits but high in biomass allocation and nitrogen content; iii) species preferring nutrient-rich environments are more plastic in their nitrogen content.Finally, a literature review was undertaken to determine which traits are determinant for annual and perennial herbaceous plants, reasoning on demographic components (reproduction, growth, survival), the importance of which differs according to the life cycle. We propose an opinion article aiming to better integrate life cycle and commonly measured morpho-physio-phenological traits.This thesis proposes a study of the relationships between functional traits and the environment at different levels of organization: between life cycles, between species, and within species. It highlights that trait-environment relationships can vary between these levels, fitting into a renewed interest in context dependency in comparative ecology

Texte intégralOs copépodes são pequenos e frágeis crustáceos que constituem um dos grupos de organismos metazoários mais abundantes do mundo. Em ambientes marinhos e estuarinos, os copépodes assumem um papel de extrema relevância ao nível das cadeias tróficas, nomeadamente na transferência de matéria e energia de níveis tróficos inferiores (fitoplâncton) para níveis tróficos superiores (ex. larvas de peixe). A importância ecológica dos copépodes reflecte-se no elevado número de citações constantes no ISI Web of Knowledge (7716 citações entre 1969 e 2006) e no destaque que os mesmos continuam a possuir em estudos recentes de planctologia marinha e estuarina. Esta dissertação teve como objectivos principais (1) descrever variações espacio-temporais em termos de abundância e biomassa de populações estuarinas de copépodes da Ria de Aveiro (Portugal) e a sua relação com parâmetros hidrológicos (salinidade, temperatura, clorofila a e precipitação; (2) comparar as taxas de crescimento e desenvolvimento de populações alopátricas de copépodes; (3) definir modelos de crescimento dependentes da temperatura para as formas juvenis (nauplius e copepoditos) de Acartia tonsa; (4) avaliar o forçamento ambiental na distribuição e abundância de populações de Acartia e (5) calcular taxas de produção secundária potenciais para as populações de Acartia. Numa primeira fase, foi objecto de estudo a comunidade de copépodes estuarinos, para a qual foram descritos os padrões temporais de abundância e biomassa e obtidas estimativas de produção secundária. Os resultados obtidos neste estudo permitiram concluir que, entre outros aspectos, a abundância e biomassa da comunidade de copépodes da Ria de Aveiro se encontra significativamente correlacionada de modo positivo com a salinidade e com a temperatura da água. As estimativas das taxas de produção secundária derivadas da aplicação de modelos gerais de crescimento mostraram ser algo diferentes, sendo a estimativa dada pelo modelo de Hunthey & Lopez (1992) mais elevada do que a obtida pelo modelo de Hirst & Bunker (2003). O crescimento e desenvolvimento de espécies de Acartia foram estudados sob condições controladas em termos de alimento e temperatura, de forma a serem definidos modelos de crescimento dependentes da temperatura. A partir destes estudos concluiu-se que as populações alopátricas possuem diferentes respostas à temperatura. Além deste aspecto, também se observou que, pelo menos no caso da A.tonsa, as taxas de crescimento das formas juvenis (nauplius e copepoditos) estimadas in situ ou sob condições saturantes de alimento são similares. resumo O forçamento ambiental das populações de Acartia no Canal de Mira foi avaliado através de uma análise de componentes principais (ACP), que permitiu a análise simultânea das alterações espaciais e temporais das diferentes populações. Esta análise identificou três zonas distintas no estuário com base na abundância de Acartia spp.. Para cada zona, análises de correlação com diferentes desfasamentos temporais entre as variáveis ambientais e a abundância de copépodes, permitiram detectar a existência de forçamentos ambientais específicos, assim como um efeito positivo da biomassa fitoplanctónica na abundância do zooplâncton verificada meses mais tarde. Esta tese demonstrou igualmente a grande importância que as populações de Acartia, especialmente a mais abundante – A. tonsa – assumem na transferência de matéria e energia no ambiente planctónico da Ria de Aveiro (Portugal).
Copepods are small fragile and tiny crustaceans that form one of the world’s most abundant groups of metazoan organisms. In estuarine and marine environments copepods assume a key role in what trophic chains are concerned, namely in the transfer of matter and energy from lower trophic levels (phytoplankton) to higher trophic levels (ex. fish larvae). Copepods ecological importance is proven by the high number of quotations in ISI Web of Knowledge (7716 quotations between 1969 and 2006) and in the significance that they still have concerning current studies on estuarine and marine planktonic studies. The main goals of the present thesis were (1) to characterize and to describe the spatialtemporal patterns of abundance, biomass and production of the estuarine copepod community from Ria de Aveiro (Portugal) and its relationship with hydrological data (salinity, temperature, chlorophyll a and rainfall regime); (2) to compare growth and developmental rates of allopatric copepod populations; (3) to define temperature dependent growth models for nauplii and copepodites of Acartia tonsa; (4) to evaluate environmental forcing on the distribution and abundance of Acartia populations; and (5) to estimate potential secondary production rates of Acartia populations. In a first stage estuarine copepods community was studied, time patterns of abundance and biomass having been described and estimates of secondary production having been obtained. Results achieved by this study have led us to the conclusion that, among other aspects, abundance and biomass of the copepods community in Ria de Aveiro is positively correlated with water salinity and temperature. Estimates of secondary production rates deriving from the use of general growth models were different, the estimate obtained by Hunthey & Lopez (1992) model being higher than the one resulting from the Hirst & Bunker (2003) one. In order to define specific temperature-dependent copepod growth models, the growth and development of Acartia species were studied under controlled conditions of food and temperature. From those studies it was concluded that allopatric populations have different temperature responses. Additionally, it was also observed that, at least for A.tonsa, the growth rates of nauplii and copepodites at saturated food conditions and in situ conditions of food are similar. Environmental forcing of Acartia populations in Canal de Mira was evaluated by means of 3-mode PCA, which analyses simultaneously spatial and temporal changes of multispecies assemblages. This analysis identified three distinct zones along the estuary based on Acartia spp. abundance. For each zone time-lagged correlations between environmental variables and copepods abundance indicated that different zones were forced by different combinations of variables and the existence of delayed effects of phytoplanktonic biomass on the abundance of A.tonsa. This thesis also demonstrated the high importance that Acartia populations, in particular the most abundant A.tonsa, assume on the transfer of matter and energy in the planktonic realm of Ria de Aveiro (Portugal).

Optimization methods have shown to be efficient at improving structural design, but their use is limited in the engineering practice by the difficulty of adapting state-of-the-art algorithms to particular engineering problems. This study proposes the use of a robust gradient-based algorithm, whose adaptation to a variety of design problems is more straightforward. The algorithm was first applied to truss geometry and beam shape optimization, both forming part of the increasingly popular class of structural form-finding problems. The results showed that the gradient-based method is an appropriate tool for defining shapes in structures. The robustness of the algorithm was verified, as a series of structural configurations were treated with similar efficiency. The gradient-based method was also applied to a more traditional structural design problem through the optimization of a steel girder, resulting in a hybrid scheme featuring a truss stiffener. Throughout the study, emphasis was laid on the practical computer implementation of the gradient-based algorithm in interaction with structural analysis tools.

Attraverso una lettura per sottosistemi, l’obiettivo è di indagare potenzialità nascoste negli intervalli di spazio tra i vari strati che compongono il sistema parete. Essa nel tempo ha assunto vari significati legati alla protezione, la sicurezza e il comfort segnando un passaggio dalla parete monolitica ad una configurazione sempre più stratificata e complessa, dove ogni elemento svolge una funzione specifica pur mantenendo compatto l’insieme. Il paradigma della sostenibilità e dei cambiamenti climatici impone strategie di riduzione dei consumi energetici, spesso esplicitati attraverso miglioramenti della componentistica degli edifici ma senza nessuna conseguenza in termini architettonici e spaziali. Isolamenti termici naturali ed artificiali, doppie e triple camere d’aria, impianti meccani ed elettrici e ventilazione meccanica controllata sono solamente alcuni dei dispositivi che regolano lo scambio tra interno ed esterno. Interrogandosi sulla profondità e la composizione della parete, la ricerca mette in luce idee e interventi capaci di dare spessore agli intervalli di spazio nascosti facendoli diventare luoghi dell’abitare intermedio, ambiguo e indeterminato. La parete intesa come elemento di organizzazione architettonica e spaziale ma allo stesso tempo come dispositivo di gestione climatica potrebbe richiamare a una nuova unione tra architettura e tecnologia, tra spazio e impianto.

Nanoscale magnetite is being examined for possible uses as an adsorbent of heavy metals and for the enhancement of water treatment processes such as stripping of trichloroethylene (TCE) from contaminated water supplies and wastewaters. Methods for recovering nanoscale magnetite must be developed before the particles can be used in water treatment processes. This is necessary because expelling high amounts of particles into the environment will be unacceptable and costly; if captured they can be reused; additionally, they could potentially cause environmental impacts due to their stability in an aqueous environment and possible toxicity. Nanoscale magnetite is superparamagnetic, so it has a high magnetic susceptibility, and hence it is very attracted to magnetized materials. Utilizing the magnetic properties of magnetite may be one possible means of separating the particles from a treatment process. High Gradient Magnetic Separation (HGMS) has been studied for the separation of micron and even tenths of a micron size particles, but there is little experimental data for HGMS of nanoscale magnetite. This research looks to filter nanoscale magnetite through a HGMS and determine the capture efficiency of the filter. Subsequently, the filter was backwashed to determine particle recover efficiencies. The flow rate was adjusted to determine the dependency of particle capture efficiency on cross sectional velocity through the filter. Additionally, particle loading was changed to better understand the correlation of particle loading with capture efficiency. Filtrations for nanoscale magnetite dispersed with sodium tripolyphosphate were also completed as well as filtrations of nanoscale magnetite coated with silica and magnetite silica composites. Experimental data in this research indicates that magnetite nanoparticles can be captured at 99.8% efficiency or higher in a well-designed filtration system. Capture efficiencies around 99.8% have been found for magnetite. The silica coated magnetite and magnetite silica composites were captured at efficiencies as high as 96.7% and 97.9%, respectively. The capture efficiency of the dispersed magnetite is lower than non-dispersed magnetite and most promising at relatively low fluid flow velocities and particle loadings. The maximum capture efficiency for dispersed magnetite particles was 90.3%. Both magnetite and dispersed magnetite were successfully recovered using backwash at pH of 10 to 11.
