The Australian dingo is an early offshoot of modern breed dogs
Dogs are uniquely associated with human dispersal and bring transformational insight into the domestication process. Dingoes represent an intriguing case within canine evolution being geographically isolated for thousands of years. Here, we present a high-quality de novo assembly of a pure dingo (CanFam_DDS). We identified large chromosomal differences relative to the current dog reference (CanFam3.1) and confirmed no expanded pancreatic amylase gene as found in breed dogs. Phylogenetic analyses using variant pairwise matrices show that the dingo is distinct from five breed dogs with 100% bootstrap support when using Greenland wolf as the outgroup. Functionally, we observe differences in methylation patterns between the dingo and German shepherd dog genomes and differences in serum biochemistry and microbiome makeup. Our results suggest that distinct demographic and environmental conditions have shaped the dingo genome. In contrast, artificial human selection has likely shaped the genomes of domestic breed dogs after divergence from the dingo

Caminhos da universidade rumo ao século XXI: pontos e estratégias para a sua orientação na visão de educadores brasileiros
A principal preocupação desse estudo é, através das reflexões nele contidas, apontar caminhos que poderão contribuir para que as nossas universidades, face à inevitável globalização, possam se instrumentalizar de forma coesa, de modo a cumprir sua missão na formação e transformação do homem. Para tal, organizamos esse trabalho sobre a universidade partindo de sua gênese, passando pelo momento atual e chegando até as perspectivas que se tem da universidade pretendida para o próximo milênio; para isso foram coletados dados que permitiram analisar alguns de seus problemas e, através dessa análise levantar possíveis soluções frente ao emergente século XXI
Role of soil carbon in the landscape functioning of the Alto São Bartolomeu watershed in the Cerrado region, Brazil
El trabajo muestra los resultados del comportamiento térmico de una vivienda social construida masivamente por el Instituto Provincial de la Vivienda (IPV), monitoreada desde el 30 de abril hasta el 05 de junio de 2008. Se localiza en la periferia norte de la capital de Catamarca y su uso es residencial. Esta conformada por porch, cocina-comedor, dormitorios y baño que totalizan una superficie de 43.04 m2. El objetivo principal es conocer el comportamiento térmico en relación a parámetros de confort. En este sentido se monitorearon y analizaron tres periodos representativos: 1) 30/04/08 al 06/05/08, 2) 18 al 24/05/08 y 3) 30/05/08 al 05/06/08. Los resultados han demostrado que cuando las condiciones de las temperaturas exteriores son más rigurosas (altas o bajas) la respuesta del diseño de su envolvente es insuficiente para alcanzar los rangos de confort térmico establecidos y como consecuencia de ello demanda mayor cantidad de energía auxiliar para su acondicionamiento.This study shows the results of the thermal behavior of a house built by the Provincial Housing Institute examined since April 30th until June 5th in the year 2008. The house is placed to the North of the Capital city of Catamarca and it is used as dwelling. It includes a porch, dining room and kitchen, bedrooms and bathroom, all comprising a 43.04m2 covered surface. The main purpose of this work is to know the thermal behavior in ralation to comfort parameters. To this end, three representative periods were observed and analysed: 1) April 30th to May 6th, 2008; 2) May 18th to May 24th, 2008; and 3) May 30th to June 5th, 2008. The results have demonstrated that, when the external weather conditions are more severe (high or low), the answer of the enveloping design is insufficient to reach the established thermal comfort ranges; as a consequence, the design demands more auxiliary power for fitting out.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES
