Mantica, Federica (Date of defense: 2023-05-11)
Regulated Gene Expression (rGE) and Alternative Splicing (rAS) are two of the main mechanisms contributing to tissue-phenotypic diversity within and between species. In this thesis, we aim at characterizing rGE and rAS ...

Les guies turístiques impreses son una font excepcional d’informació per a futurs turistes. Aquests llibres proporcionen consells, suggeriments, pistes, recomanacions i molt més per a que el viatger pugui entendre el Destí ...
Carnicero Campmany, Pau (Date of defense: 2017-06-16)
Des de temps ancestrals la diversitat d’éssers vius del planeta ha fascinat i intrigat la humanitat. Com s’originen les espècies? Com han assolit la distribució geogràfica actual? En les darreres dècades, el gran avenç de ...
Rizzo, Valeria (Date of defense: 2015-10-08)
The general aim of this dissertation is to investigate the evolution, the diversification and some ecological traits of the species of the strictly subterranean genus Troglocharinus Reitter, 1908. The genus Troglocharinus ...
Valles Ibáñez, Guillem de (Date of defense: 2016-11-16)
Human genomes have been found to harbor an unexpected number of ~100 loss-of-function (LoF) variants, with ~20 of them in an homozygous state, in most cases without a visible effect despite its potential truncation of ...
Lopes Durão, Ana Filipa (Date of defense: 2023-06-01)
Els estudis ontogenètics comparatius entre espècies filogenèticament properes amb diferents tipus de locomoció són essencials per comprendre en quina mesura la funció pot afectar les diferents etapes del desenvolupament ...
Ponce López, Víctor (Date of defense: 2016-06-02)
The representation (or feature) learning has been an emerging concept in the last years, since it collects a set of techniques that are present in any theoretical or practical methodology referring to artificial intelligence. ...
Ibáñez Marcelo, Esther (Date of defense: 2014-12-19)
In this thesis we develop a multi-scale model of the evolutionary dynamics of a population of cells, which accounts for the mapping between genotype and phenotype as determined by a model of the gene regulatory network. ...
Blevins, William Robert (Date of defense: 2020-01-17)
All living organisms respond to environmental stimuli by modulating the activity of different genes. This response can occur across many locations throughout the cell such as at the level of transcription, translation, and ...
Pedro Rodríguez, Manuel de (Date of defense: 2021-04-19)
L’interès per els processos eco-evolutius que determinen la capacitat d’expansió de la distribució de les espècies ha incrementat recentment com a conseqüència de l’increment de velocitat del canvi climàtic i global. Alguns ...
Gigli, Elena (Date of defense: 2011-06-20)
The evolutionary history of H. neanderthalensis, interwoven with that of H. sapiens, has always fascinated the scientific world. Recent adavncess in paleogenetics shedds new light on the phylogenetic relationship between ...
Sikora, Martin (Date of defense: 2010-06-04)
Una de les forces selectives més fortes que han afectat a les poblacions humanes en la història més recent és el paràsit de la malària: Plasmodium falciparum, que és la causa de varis exemples d'adaptació induïda per ...
Escuer Pifarré, Paula (Date of defense: 2022-12-21)
[eng] During the last decade, advances in high-throughput sequencing (HTS) technologies have increased exponentially the generation of genomic data, especially of non-model species. In this thesis, we generated and used ...
Mora de Checa, Elisa (Date of defense: 2015-12-14)
Mygalomorphs is a cosmopolitan group that inhabits all the continents except Antarctica. The group and has been commonly described as ‘primitive’ because of the retention of plesiomorphic characters, such as the presence ...
Ferrer Obiol, Joan (Date of defense: 2021-03-19)
How populations differentiate and become new species is a foundational question to the field of evolutionary biology and has important implications for the generation of both local and global patterns of species-level ...
Querejeta Coma, Marina (Date of defense: 2017-07-21)
The study of intraspecific diversity is essential in ecology and evolution as they reveal fine-scale patterns and it is crucial in conservation planning. The main aim of this thesis is to study the evolutionary history of ...
Hernando Herráez, Irene (Date of defense: 2015-07-24)
DNA methylation is a crucial epigenetic modification involved in numerous biological processes. However, despite its functional importance, the evolutionary history of this modification and the mechanisms diving such changes ...
Esteller Cucala, Paula (Date of defense: 2023-04-18)
Changes in the epigenetic regulation of gene expression have important implications for evolution. However, the study of these changes (i) has not been consistently assessed across closely related species, (ii) oftentimes ...
García Pérez, Raquel (Date of defense: 2019-01-29)
The evolution of the human phenotype involved gene regulatory innovations. Comparative functional epigenomic studies are a powerful tool with potential to shed light on many long-standing questions regarding human evolution. ...
Ponti de la Iglesia, Raquel (Date of defense: 2018-11-16)
One of the most fascinating aspects of birds is their capability of migrate from one area to another throughout the year. Unravelling the patterns and processes involved in the evolution of migration is paramount to ...
