Biological invasions are a grave threat to ecosystems. The black garden ant (Lasius niger) is a pest species in Europe. Current literature states that L. niger occupies a disjunct native distribution in the Holarctic, however, based on recent work, we re-evaluate this distribution. [...]

18 p, 4.7 MB Why Do Cryptic Species Tend Not to Co-Occur? A Case Study on Two Cryptic Pairs of Butterflies / Voda, Raluca (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Dapporto, Leonardo (Oxford Brookes University. Department of Biological and Medical Sciences) ; Dinca, Vlad Eugen (University of Guelph. Biodiversity Institute of Ontario) ; Vila Ujaldón, Roger (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona))
As cryptic diversity is being discovered, mostly thanks to advances in molecular techniques, it is becoming evident that many of these taxa display parapatric distributions in mainland and that they rarely coexist on islands. [...]

Widespread population declines have been reported for diverse Mediterranean butterflies over the last three decades, and have been significantly associated with increased global change impacts. The specific landscape and climatic drivers of these declines remain uncertain for most declining species. [...]

216 p, 7.3 MB Biodiversity and comparative phylogeography of western Mediterranean butterflies / Vodă, Raluca ; Vila Ujaldón, Roger, dir. ; Dapporto, Leonardo, dir. ; Ruiz, Alfredo, (Ruiz Panadero) tut. (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia
Esta tesis doctoral se basa en un enfoque macroecológico y en análisis de grandes conjuntos de datos para el estudio de la biodiversidad y filogeografía de las mariposas mediterráneas occidentales. [...]
This PhD thesis consists in a comprehensive macroecological approach and in analyses of large datasets to study the biodiversity and phylogeography of western Mediterranean butterflies. One of the most important and original contributions of this PhD was creating a comprehensive butterfly DNA and tissues collection for the western Mediterranean and improving the occurrence data for island and mainland communities.

11 p, 2.5 MB Unprecedented within-species chromosome number cline in the Wood White butterfly Leptidea sinapis and its significance for karyotype evolution and speciation / Lukhtanov, Vladimir A. (Zoological Institute of Russian Academy of Science (Sant Petersburg, Rússia)) ; Dinca, Vlad Eugen (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Talavera Mor, Gerard (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Vila Ujaldón, Roger (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona))
Background: Species generally have a fixed number of chromosomes in the cell nuclei while between-species differences are common and often pronounced. These differences could have evolved through multiple speciation events, each involving the fixation of a single chromosomal rearrangement. [...]

15 p, 1.2 MB What is the phylogenetic signal limit from mitogenomes? The reconciliation between mitochondrial and nuclear data in the Insecta class phylogeny / Talavera Mor, Gerard (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Vila Ujaldón, Roger (Institut de Biologia Evolutiva (UPF-CSIC) (Barcelona))
Background: Efforts to solve higher-level evolutionary relationships within the class Insecta by using mitochondrial genomic data are hindered due to fast sequence evolution of several groups, most notably Hymenoptera, Strepsiptera, Phthiraptera, Hemiptera and Thysanoptera. [...]

La història evolutiva dels insectes és llarga i complexa. Inferir les relacions evolutives dels insectes, amb la seva fascinant diversitat, és encara avui un gran repte, fins i tot amb les recents aportacions teòriques i tecnològiques. [...]
Insects have had a complex and long evolutionary history. Mapping the evolutionary relationships of insects, with their stunning diversity, remains a challenge, even in light of new theory and technology. [...]

59 p, 783.2 KB Caracterització estructural de pèptids dels dominis terminals de la histona H1 / Vila Ujaldón, Roger ; Suau León, Pere, dir. (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular) ; Ponte Marull, Immaculada, dir. (Universitat Autònoma de Barcelona. Departament de Bioquímica i de Biologia Molecular)
La histona H1 és una de les proteïnes que participen en la formació de la superestructura de la cromatina. Aquesta proteïna està formada per tres dominis: una regió globular central flanquejada per cues N- i C-terminals hidrofíliques i bàsiques, molt riques en lisina, alanina i prolina. [...]
Histone H1 is one of the proteins that participate in chromatin condensation. This protein has a three domain structure: a globular central region and two N- and C-terminal tails. These tail domains are hydrophilic and basic, very rich in lysine, alanine and proline. [...]
