Is scrúdú ar théacs amháin, Comthóth Lóegairi co Cretim ocus a Aided (CLcC), a chaomhnaítear i lámhscríbhinn amháin, Lebor na hUidre (LU), atá sa tráchtas seo. Bíodh is gurb é LU an lámhscríbhinn Ghaelach is sine a chaomhnaíonn scéalta leanúnacha i nGaeilge, agus gur ábhar staidéir ar leith i ngort na Gaeilge agus na Ceiltise é dá réir, níor scrúdaíodh CLcC as féin mar earra litríochta fós, ná ní dhearnadh mionscrúdú ar an teanga ann ach chomh beag. Ceapadh gur mhithid an téacs a mheas ar na cúiseanna sin. Roinntear an tráchtas ina dhá chuid, mar atá: (a) cuid a haon, a chuireann síos ar chomhthéacs na lámhscríbhinne agus ar cheisteanna a bhaineann lena lucht scríofa, chomh maith le hanailís liteartha ar théamaí a luaitear sa téacs féin. Déantar ceist an rangaithe a phlé chomh maith, is é sin, conas is ceart rangú a dhéanamh ar CLcC; (b) cuid a dó, is eagrán agus aistriúchán den téacs atá inti, chomh maith le nótaí teanga a scrúdaíonn gnéithe suntasacha den teanga, agus gluais. An dá shórt anailíse a chuirtear chun cinn i rith an tráchtais, .i. an scrúdú liteartha agus an t-iniúchadh ar an teanga, déantar iad a shuíomh i gcomhthéacs LU trí chéile oiread agus is féidir. Féachann an cur chuige seo le taispeáint gur de dhlúth na lámhscríbhinne féin na téamaí (mar shampla creideamh, cumhacht, ríogacht) is bun le CLcC, agus gur sampla an-spéisiúil de thoisí teanga LU an téacs seo, óir léiríonn sé caomhnú ábhar ón tSean-Ghaeilge chomh maith le forbairtí teanga a bhaineann le ré na Meán-Ghaeilge. Sna nótaí teanga, leis, cuirtear samplaí as lámhscríbhinní comhaimseartha eile san áireamh, chomh maith le foinsí níos sine ná sin, le bonn a chur faoin áitiú a dhéantar ar aois na teanga in CLcC.

In sexually reproducing organisms, the specific combinations of parental alleles can have important consequences on offspring viability and fitness. Accordingly, genetic relationship between mates can be used as a criterion for mate choice. Here, we used microsatellite genetic markers to estimate the genetic relationship between mating pairs in the wild boar, Sus scrofa. Males, females and foetuses proceeding from Portugal, Spain and Hungary were genotyped using 14 microsatellite markers. The genetic relationship between mates was estimated using different measures of foetus heterozygosity. We found that the observed heterozygosity of foetuses was lower than that expected under random mating. This result occurred mainly when Sd2 (relatedness of parental genomes) was used as the heterozygosity measure. After simulations, we concluded that the observed low heterozygosity was possibly due to outbreeding avoidance. Outbreeding avoidance based on genetically different genomes might play an important role in species evolution and its genetic conservation.
