Texto completoIn this thesis the genetic variation of two grouse species, the Chinese grouse (Bonasa sewersowi) and the Black grouse (Tetrao tetrix) was examined with neutral genetic markers: microsatellites. Habitat fragmentation and isolation leads to structuring among and loss of genetic variation within populations.
The Chinese grouse in a small population in Lianhuasan nature reserve was found to have undergone a population bottleneck and as a result of isolation and possible inbreeding showed genetic impoverishment hereof.
The Black grouse populations in Europe face various different conditions from widely distributed areas of suitable habitat in the northern and eastern parts of its range to highly naturally and anthropogenically fragmented habitat landscapes in the west.
Structure among populations was found in Great Britain where Wales, Scotland and England showed characteristics of three different genetic entities, indicating very little or no geneflow between these populations.
The Dutch population showed signs of loss of genetic variation as to be expected from a population that has historically decreased in population size from several thousands to tens of individuals in a matter of decades. However the possibility to spot signs of a bottleneck was impaired due to the short time-window in which this can be observed in a population with such a low effective population size (NE).
The sampled populations in Europe clustered into five different groups of genetic identities. The different clusters were: Great Britain-, the Netherlands-, Fenno-Scandian-, Alpine- and lowland German-Austrian populations. The level of genetic variation when compared over all these different populations decreased as a sign of isolation and small NE. However it was not feasible to separate the impact of these two factors.

This thesis is a collection of papers in which behavior genetic methods are used to shed light on individual differences in economic preferences, behaviors and outcomes. Chapter one uses the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving. The paper reports evidence that these preferences are broadly heritable, with estimates suggesting that genetic differences explain approximately twenty percent of individual variation. The results thus point to genes as an important source of individual variation in preferences, a source which has hitherto been largely neglected in the economics literature. The chapter is written with Christopher T. Dawes, Magnus Johannesson, Paul Lichtenstein and Bjorn Wallace. Chapter two shows that these findings also extend to the field. Following a major pension reform in the late 1990s, all Swedish adults had to form a portfolio from a large menu of funds. Matching individual investment decisions to the Swedish Twin Registry, the paper finds that approximately 25% of individual variation in portfolio risk is due to genetic variation. The results, which are complementary to those reported in chapter one, also hold for several other aspects of financial decision-making. The chapter is written with Magnus Johannesson, Paul Lichtenstein, Orjan Sandewall and Bjorn Wallace. Chapter three uses two complementary Swedish datasets to examine the importance of family environment in explaining variation in income, educational attainment, and measures of cognitive and non-cognitive skills. Using seven different sibling types who differ in their degree of genetic relatedness and rearing status, I find moderate family effects on educational attainment, cognitive skills and non-cognitive skills. This contrasts with the effects of family on income, which are low. Additional analyses, based on a sample of identical (MZ) and fraternal (DZ) twins for which more comprehensive income data is available, reveal large and persistent separation of the MZ and DZ correlations over the entire lifecycle, except at very early ages. One interpretation of this finding is that there are strong family effects on the timing of labor market entry. I discuss the relevance of these results for efforts to understand the causes of income inequality.

Texto completoQuesta tesi riassume l’attività di ricerca da me svolta durante i tre anni di dottorato, sovvenzionato dal progetto ERC LanGeLin, il cui scopo principale è di migliorare le conoscenze sulla co-evoluzione di lingue e geni. I progetti descritti condividono l’uso di marcatori uniparentali usati per gli studi di evoluzione umana, ma differiscono per la combinazione di metodi molecolari e statistici. La Parte I descrive lo stato dell’arte dei marcatori uniparentali e i pro e contro del loro utilizzo in ambito linguistico e archeologico. La Parte II riassume i risultati delle ricerche condotte nell’ambito del progetto LanGeLin che descrive la diversità dei pattern genetici e linguistici in 36 popolazioni Euroasiatiche. Il progetto LanGeLin (Language and Gene Lineages), finanziato dal “European Research Council” ha lo scopo di testare l’ipotesi di Darwin presentata in “Origine delle specie”. Darwin intuì che l’albero filogenetico delle diverse sottospecie umane, potesse sovrapporsi a quello ottenuto a partire dalle diverse lingue, offrendo di fatto la possibilità di studiare la genealogia delle lingue e allo stesso tempo capire come le differenze tra queste avrebbero permesso di far luce sugli aspetti elusivi della storia demografica umana. R. Sokal e L.L. Cavalli-Sforza nel 1988 hanno elucidato come la comparazione dei vocaboli rifletta la correlazione fra variabilità genetica e linguistica nelle maggiori famiglie linguistiche ma, a causa di metodi linguistici, risulta difficile comparare popolazioni derivanti da gruppi linguistici distanti. Il nuovo metodo linguistico PCM si basa sulle caratteristiche linguistiche più stabili della sintassi. È stato dunque possibile, anche in questa tesi, testare su larga scala geo-linguistica la correlazione tra dati genetici e linguistici. Lo studio delle discendenze materne e paterne è stato condotto separatamente per indagarne le relative storie di migrazione: due differenti storie sono emerse dall’analisi del Ychr (discendenza patrilineare) e del mtDNA (discendenza matrilineare). Non ovvie considerazioni sono scaturite dalla comparazione delle caratteristiche genetiche e linguistiche, che ha portato a definire come la correlazione tra lingue e sequenza genetica sia dipendente dall’area geografica e dai marcatori genetici considerati. La Parte III descrive l’analisi di sequenze di mtDNA del Mesolitico (Ms) che ci ha permesso di indagare sul popolamento della Sardegna in periodo Neolitico (Ne) e pre-Neolitico (pN). Lo studio è stato incentrato su due sequenze mitocondriali sarde Ms in relazione al contesto europeo. C’è ancora molta incertezza sulla variabilità genetica della Sardegna preistorica, a causa della scarsità di resti umani Ne. Dal punto di vista genetico, i sardi moderni possono considerarsi un gruppo a se stante rispetto al resto dell’Europa continentale, mostrando alti livelli di diversità interna e una forte vicinanza con i primi coltivatori europei del Ne. Questa tesi riporta le due prime sequenze mtDNA complete sarde, datate circa 10000 anni fa. I due individui confermano un’occupazione mesolitica dell’isola e rappresentano un aplotipo mai trovato prima in Sardegna mesolitica e con basse frequenze nell’intera Europa. Le due sequenze risultano ben differenziate se comparate con altri dati europei pN, e più simili a popolazioni dell’era pre-glaciale che a popolazioni coeve. Analisi di inferenza Bayesiana hanno mostrato come i primi abitanti dell’isola abbiano contribuito poco al popolamento attuale dell’isola, la cui diversità genetica deriva da migrazioni dal continente in tempi neolitici. Un progetto portato avanti parallelamente, ha riguardato lo studio di frequenze alleliche in gemelli dizigotici provenienti da popolazioni umane africane, europee ed asiatiche. Le tecniche bioinformatiche e biostatistiche usate per le analisi genomiche su larga scala, fanno da collante con i precedenti progetti descritti.
