Full textAn extensive knowledge about population responses to ongoing environmental and climatic changes is a primary goal to enhance environmental policies and promote biodiversity conservation. The capacity of a population in responding to rapid changes occurring within ecosystems is one of the most important aspects that can determine its trajectory over space and time. This thesis describes four studies that analyse some long-term responses of bird populations from both a methodological and applicative point of view, providing novel and valuable findings not only for bird studies but also in a broad ecological perspective. The first research focused on some methodological issues in population trend modelling. Changes in population size over time (i.e. population trends) are one of the clearest responses of populations to environmental changes and represent a key tool for wildlife conservation. Thus, improving the capacity of estimating trends is pivotal. The study investigated the effects of the environmental bias, which may affect many existing surveys because of a variation in the sampling effort or design over space and time, and of two statistical properties of count data, namely overdispersion and zero inflation, on the estimation process of population trends. A multi-step modelling approach was proposed, and findings highlighted that the environmental bias was the most important factor that causes differences in trend estimates across models. Additionally, overdispersion and zero inflation can influence, also significantly, the estimates, and modelling frameworks should consider their evaluation in the statistical approach. In the second work, this modelling framework was applied to assess the long-term population trends for common breeding birds at regional scale (northern Italy). Additionally, through a trait-based approach, the study investigated whether species with similar life-history and ecological traits shared similar population dynamics. Findings allowed identifying species that need more conservation attention and for which management measures are required to avoid further population declines. The trait-based approach allowed identifying which ecological and functional groups need greater attention, emphasising the usefulness of traits’ information to plan further studies aimed at identifying the drivers at the basis of the observed population changes. Then, the third study focused on niche modelling to understand whether a species can adapt its realised Grinnellian niche along relatively long-term periods as results of ongoing environmental changes. Moreover, the study assessed whether the observed changes were linked to population trends, obtained from the previous work, and to species traits. The multi-species analysis on common breeding birds highlighted that niche conservatism is not a ubiquitous condition, and some species are changing their niches. Findings also showed the existence of non-random associations between niche changes and both population trends and groups of species sharing similar life-history and ecological traits. The last research dealt with assessing the effects of climate change on bird populations focusing on the extreme climatic events, which exacerbation and increase in frequency poses new global challenges for nature conservation. Using the UK Breeding Bird Survey, a long-term large-scale monitoring program, a multi-species analysis investigated how populations respond to extreme climatic events and which species are more sensitive to such climatic conditions. Findings highlighted widespread effects of extreme climatic events on the abundance of bird populations, suggesting that they could be a key driver for shaping future population dynamics. Long-term data revealed to be extremely important for assessing responses of populations in a changing environment and are essential to achieve a comprehensive perspective of ecological processes that can affect biocenoses and ecosystems.

Full textThe present work focus on the concepts of identità, subjectivity and intersubjectivity that substain sense-making processes in individuals (Galimberti, 2011). The first study is about new Identity positions and self congruence. Participants report that their identities are different from each other and their Self; at identity level they report that their identities change over time, but their sle f congruence does not. The second research is focused on the link between utterance subjectivity and construction of coherency in narrations. Nine blogs were analyzed and results show that bloggers express their subjectivity differently in each post, and thank to narrative processes (coherence and reflexivity) and to enunciation they can make sense of their own experiences. The third research here presented studies the processes that underlies the creation of intersubjectivity in a group working online and face to face. Results show that intersubjective results of interactions change over time, but there is isomorphism between the processes of creating intersubjectivity online and face to face.

Full textLe malattie metaboliche ereditarie (MME), o difetti congeniti del metabolismo, rappresentano un vasto ed eterogeneo sottogruppo di malattie genetiche caratterizzate dalla disfunzione di un enzima, di una proteina o di altre molecole più complesse coinvolte nel metabolismo cellulare, con conseguente perturbazione dello stesso. La valutazione della qualità della vita percepita dal soggetto rappresenta in medicina un aspetto molto importante al fine di enfatizzare l'importanza dei bisogni percepiti da ciascun paziente. L'obiettivo del presente studio inizialmente è nato dalla volontà di analizzare quali variabili potessero influenzare maggiormente la percezione soggettiva di una buona qualità di vita, in pazienti affetti da una patologia metabolica. Durante il corso dello studio l'attenzione si è spostata principalmente sull'analisi della funzionalità cognitiva, intesa come variabile notevolmente influenzante la percezione che ogni paziente ha relativamente, al proprio benessere fisico e psicologico. A questo proposito si riporta l'analisi compiuta su di un gruppo di pazienti affetti da Galattosemia, con l'obiettivo di : valutare e quantificare le funzioni cognitive, stabilire una possibile correlazione tra genotipo e fenotipo del campione, valutare l'eventuale relazione esistente tra il quadro biochimico di ogni singolo paziente (livelli di galattosio totale plasmatico) ed il quadro neuropsicologico e neurologico. E' stata analizzata in modo retrospettivo la storia clinica di 7 pazienti con galattosemia, 3 in età pediatrica e 4 in età adulta. Le alterazioni cognitive evidenziate in modo eterogeneo nel campione adulti sono: aprassia verbale, aprassia costruttiva,deficit delle capacità attentive,alterazioni delle capacità percettivo gnosiche. Ad un'attenta analisi dei pazienti inoltre, emerge la presenza di specifici aspetti di personalità.
