Partition of the genetic variability, genetic structure and relationships among seven Spanish Celtic horse breeds were studied using PCR amplification of 13 microsatellites on 481 random individuals. In addition, 60 thoroughbred horses were included. The average observed heterozygosity and the mean number of alleles were higher for the Atlantic horse breeds(More)
Global change is impacting forests worldwide, threatening biodiversity and ecosystem services including climate regulation. Understanding how forests respond is critical to forest conservation and climate protection. This review describes an international network of 59 long-term forest dynamics research sites (CTFS-ForestGEO) useful for characterizing(More)
Data from 2 Asturiana breeds’ herdbooks were analysed to study their genetic structure. Herds were assigned to 3 levels by the use of herd sires. Generation intervals averaged 5.3 (Casina) and 5.4 (Carreiiana) yr, and for both breeds sires were significantly younger than dams. Determination of the important herds shows the contribution of Caso county (60%)(More)
Ten genetic markers were studied in seven Spanish native cattle breeds, using a total of 725 animals. Of the ten, two were found to be monomorphic in all seven breeds. The genetic relationships of the seven breeds are estimated by three different genetic-statistical methods (genetic distances, main coordinate analysis and cluster analysis), which indicate(More)
The existence of polymorphism for erythrocyte potassium (Ke) is confirmed in certain Spanish breeds of goat. A statistical boundary is established between two caprine populations: low (LK) and high (HK) red cell potassium, the dividing line being set at 45 m-equiv/l of Ke. Both types are shown to be controlled genetically by an autosomal locus with two(More)
1. The structure of the Pirenaica, Verata, Guadarrama, Zamorana, Berciana, Granadina, Blanca Andaluza, Blanca Celtibérica, Murciana, Negra Serrana, Malagueña, Canaria, Palmera and Retinta goat breeds have been analysed. 2. Fourteen blood genetic systems were analysed: reduced glutathione (GSH), red cell potassium (Ke), haemoglobin (Hb), diaphorase (Dia),(More)
The genetic distances separating 14 Spanish goat breeds are calculated from gene frequency data of 14 genetic blood markers (GSH, Ke, Hb, Dia, Ct, MDH, CA, X, NP, Alp, Am, Cp, Tf and Al). Working from the matrix of Nei's genetic distances we drew a dendrogram demonstrating a great genetic similarity among populations from Negra Serrana, Zamorana,(More)
This paper describes for the first time polymorphism of the erythrocyte diaphorase in goats. Three diaphorase 1 phenotypes were observed in the red cells of goats. Breeding data indicated that polymorphism was controlled by two autosomal codominant alleles, DiaF and DiaS, the frequencies of which were determined in 14 different Spanish breeds of goat.
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) are a family of unintentionally produced persistent organic pollutants (POPs) that have received considerable public and scientific attention due to the toxicity of some of their congeners, more specifically those with chlorine substitution in the 2,3,7,8 positions. The environmental management(More)
Toxic polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) may be formed during remediation of chlorinated phenols via Fenton oxidation. To highlight the need for monitoring the production of toxic byproducts in these reactions, this work assessed the influence of iron dose (0.09-0.36 mM) on the Fenton oxidation of 2-chlorophenol (2-CP, 15.56 mM),(More)
