The genome sequencing of an albino Western lowland gorilla reveals inbreeding in the wild

BACKGROUND: The only known albino gorilla, named Snowflake, was a male wild born individual from Equatorial Guinea who lived at the Barcelona Zoo for almost 40 years. He was diagnosed with non-syndromic oculocutaneous albinism, i.e. white hair, light eyes, pink skin, photophobia and reduced visual acuity. Despite previous efforts to explain the genetic cause, this is still unknown. Here, we study the genetic cause of his albinism and making use of whole genome sequencing data we find a higher inbreeding coefficient compared to other gorillas.RESULTS: We successfully identified the causal genetic variant for Snowflake's albinism, a non-synonymous single nucleotide variant located in a transmembrane region of SLC45A2. This transporter is known to be involved in oculocutaneous albinism type 4 (OCA4) in humans. We provide experimental evidence that shows that this amino acid replacement alters the membrane spanning capability of this transmembrane region. Finally, we provide a comprehensive study of genome-wide patterns of autozygogosity revealing that Snowflake's parents were related, being this the first report of inbreeding in a wild born Western lowland gorilla.CONCLUSIONS: In this study we demonstrate how the use of whole genome sequencing can be extended to link genotype and phenotype in non-model organisms and it can be a powerful tool in conservation genetics (e.g., inbreeding and genetic diversity) with the expected decrease in sequencing cost.

Assessment of microbial community structure changes by amplified ribosomal DNA restriction analysis (ARDRA)

Amplified ribosomal DNA restriction analysis (ARDRA) is a simple method based on restriction endonuclease digestion of the amplified bacterial 16S rDNA. In this study we have evaluated the suitability of this method to detect differences in activated sludge bacterial communities fed on domestic or industrial wastewater, and subject to different operational conditions. The ability of ARDRA to detect these differences has been tested in modified Ludzack-Ettinger (MLE) configurations. Samples from three activated sludge wastewater treatment plants (WWTPs) with the MLE configuration were collected for both oxic and anoxic reactors, and ARDRA patterns using double enzyme digestions AluI+MspI were obtained. A matrix of Dice similarity coefficients was calculated and used to compare these restriction patterns. Differences in the community structure due to influent characteristics and temperature could be observed, but not between the oxic and anoxic reactors of each of the three MLE configurations. Other possible applications of ARDRA for detecting and monitoring changes in activated sludge systems are also discussed

Marta Pessarrodona, traductora

Marta Pessarrodona és una de les traductores més representatives del segle XX en llengua catalana i castellana, juntament amb altres noms femenins que han cultivat l’art de la traducció com Maria Antònia Salvà, Carme Montoriol, Maria Teresa Vernet, Carme Serrallonga, Maria Aurèlia Capmany, Montserrat Abelló, Roser Berdagué, Maria Àngels Anglada, HelenaValentí, Maria Antònia Oliver, Maria Mercè-Marçal, entre d’altres. Tanmateix, per a la majoria, la tasca de torsimanys correspon a una activitat secundària per aquestes autores, en tant que prioritzen la seva faceta com a escriptores i l'ofici de la traducció sovint respon a una voluntat econòmica. De la mateixa manera, Marta Pessarrodona també ha destacat en altres camps de la literatura, concretament en la poesia, però també en l’assaig i la narració curta. Malgrat això, en tota la seva obra té intrínseca la traducció tant pel recurs d’usar paraules d’altres idiomes com també per la temàtica de les seves obres. La seva passió per les diferents llengües i cultures la porten a voler donar-les a conèixer a la nostra llengua i cultura, i per aquest motiu, té una prolífica activitat traductora, que ha restat sempre en la penombra, eclipsada per la seva activitat com a autora, principalment poeta, però també assagista, dramaturga, prologuista i articulista. L’activitat traductològica de Pessarrodona l’ha acompanyat al llarg de la seva carrera com a autora i ha publicat un llarg llistat d’obres, majoritàriament d’autores de parla anglesa, en llengua catalana i castellana. Tanmateix, tot i l’aportació tan important que ha realitzat a la nostra cultura a través de la traducció, la faceta de Marta Pessarrodona com a traductora no ha estat gaire estudiada enfront a la seva activitat com a escriptora, que gaudeix de més rellevància. És per aquest motiu que volem donar reconeixement a aquesta activitat en la qual Pessarrodona hi ha dedicat tant temps i esforç i que ens ha apropat obres cabdals de la literatura universal. Així doncs, l’objectiu principal d’aquest treball és donar a conèixer la faceta traductora de Marta Pessarrodona amb la finalitat de recuperar les veus traductològiques de la nostra història literària. Cal entendre aquesta traductora en relació amb el conjunt de la tradició literària alhora que en el context d’una geneologia femenina de la literatura que ha començat a esbossar-se d’un temps ençà.

Rapid radiation in spiny lobsters (Palinurus spp) as revealed by classic and ABC methods using mtDNA and microsatellite data

Background: Molecular tools may help to uncover closely related and still diverging species from a wide variety of taxa and provide insight into the mechanisms, pace and geography of marine speciation. There is a certain controversy on the phylogeography and speciation modes of species-groups with an Eastern Atlantic-Western Indian Ocean distribution, with previous studies suggesting that older events (Miocene) and/or more recent (Pleistocene) oceanographic processes could have influenced the phylogeny of marine taxa. The spiny lobster genus Palinurus allows for testing among speciation hypotheses, since it has a particular distribution with two groups of three species each in the Northeastern Atlantic (P. elephas, P. mauritanicus and P. charlestoni) and Southeastern Atlantic and Southwestern Indian Oceans (P. gilchristi, P. delagoae and P. barbarae). In the present study, we obtain a more complete understanding of the phylogenetic relationships among these species through a combined dataset with both nuclear and mitochondrial markers, by testing alternative hypotheses on both the mutation rate and tree topology under the recently developed approximate Bayesian computation (ABC) methods. Results Our analyses support a North-to-South speciation pattern in Palinurus with all the South-African species forming a monophyletic clade nested within the Northern Hemisphere species. Coalescent-based ABC methods allowed us to reject the previously proposed hypothesis of a Middle Miocene speciation event related with the closure of the Tethyan Seaway. Instead, divergence times obtained for Palinurus species using the combined mtDNA-microsatellite dataset and standard mutation rates for mtDNA agree with known glaciation-related processes occurring during the last 2 my. Conclusion The Palinurus speciation pattern is a typical example of a series of rapid speciation events occurring within a group, with very short branches separating different species. Our results support the hypothesis that recent climate change-related oceanographic processes have influenced the phylogeny of marine taxa, with most Palinurus species originating during the last two million years. The present study highlights the value of new coalescent-based statistical methods such as ABC for testing different speciation hypotheses using molecular data.

Líderes obreros y vanguardias culturales: la presencia del obrerismo en la Barcelona de la primera posguerra europea

Teresa Abelló analyses here an aspect of Barcelona's socio-cultural life in the period that goes from the first to the Second World War. She concentrates her attention on a new model of working-class leader that have promoted a clear cut with XIX century internationalist leading manual workers. The new manners embodied on the person of Salvador Seguít, he General Secretary of the anarchosyndicalist CNT. Abelló points aout at the same time . the relationship between these new social habits and the cultural avantgardes of the moment -either literary, pictoria or artistic in general.

Economic and legal analysis of mandatory non-recourse mortgages with applications to Spain

“The liquidity crisis of the Spanish banks is largely due to the lack of confidence of foreign investors and, therefore, the changes that occur in the legislation should not affect the credibility, stability, legal certainty, predictability that markets expect”.Sergio Nasarre (2011)In the current situation of economic crisis, many people have found they can no longer pay back the mortgage loans that were granted to them in order to purchase a dwelling. It is for this reason that, in light of the economic, political and social problems this poses, our paper studies the state of the Spanish real-estate system and of foreclosure, paying special attention to the solution that has been proposed recently as the best option for debtors that cannot make their mort-gage payments: non-recourse mortgaging. We analyze this proposal from legal and economic perspectives in order to fully understand the effects that this change could imply. At the same time, this paper will also examine several alternatives we believe would ameliorate the situation of mortgage-holders, among them legal reforms, mortgage insurance, and non-recourse mortgaging itself.
