The various species of avian scavengers in southern Spain concentrated on different parts of the carcasses. A facilitatory effect of vultures and Wild Boars on Magpies and kites were detected, as ...well as an inverted (inhibitory) effect when short-period records were considered. After a directionality index of aggressive behaviour was obtained, it was shown that within the same species either threats, attacks, or fights occur, whereas among different species the smaller size scavengers mainly direct attacks towards those of greater size and the latter mainly threaten the smaller ones. When the response to other individuals was recorded, an interspecific hierarchy pattern was detected. The intraspecific response made apparent a gradient of increasing tolerance from Magpies to kites and vultures.
Plasma 25-hydroxycholecalciferol (25OHD3) has been measured by means of gas-liquid chromatography (HPLC) in 23 healthy mothers and their normal full term babies. It was measured as well in twelve ...infants, nine children of 1.5-5 years and in 57 schoolboys of 5-12 years. Infant population showed a wide variation of plasma 25OHD3 (m +/- SEM) being 16.4 +/- 1.45 ng./ml. Children 1.5-5 years old showed 12.7 +/- 2.3 ng./ml. which is lower than expected. Schoolboys showed a normal values of 22.9 +/- 1.3 ng./ml. These differences are believed to be due to a great sunshine exposition. In perinatal group, births taking place in winter showed a very low level of 25OHD3 (m +/- SEM) in mothers (6.9 +/- 1.8 ng./ml.) and consequently in their newborns (5.3 +/- 1.6 ng./ml.). Those taking place in summer showed significantly higher figures for both mothers (18.9 +/- 2.7 ng./ml.) and newborns (12.9 +/- 2.4 ng./ml.). A good correlation (r = 0.83) between plasma levels of mothers and newborns is found.

Repositorio Documental de la Universidad de Salamanca - Data provided by Europeana Collections- ES Se estudian las comunidades herbáceas vivaces de lindero de bosque, ...en los pisos meso y supramediterráneo de las provincias Luso-Extremadurense y Carpetano-Ibérico-Leonesa (sectores salmantino, bejarano-gredense, lusitanoduriense y orensano-sanabriense), pertenecientes a la clase Trifolio-Geranietea Müller 1961. Hemos intentado fijar el comportamiento sintaxonómico de un conjunto de taxones, en su mayor parte endémico, que definen y diferencian las comunidades estudiadas frente a sus vicariantes septentrionales europeas. Finalmente, proponemos como nuevas las asociaciones Hieracio-Linarietum triornithophorae, Carduo-Festucetum durandii (Linarion triornithophorae), Vincetoxico-Origanetum virentis y Pimpinello-Origanetum virentis (Origanion virentis).- EN In this work we study the herbaceous perennial communities of the edges in the mesomediterranean and supramediterranean stages of the Luso- Extremadurense and Carpetano-Ibérico-Leonesa provinces (salmantino, bejaranogredense, lusitano-duriense and orensano-sanabriense sectors). These communities belong to the phytosociological class Trifolio-Geranietea Müller, 1961. We have tried to settle the syntaxonomic behaviour of a few taxa —most of them endemic ones— which determine the studied communities and separate them from their northern Europe vicarious. Finally, we propound the new associations Hieracio-Linarietum trionithophorae, Carduo-Festucetum durandii (Linarion triornithophorae), Vincetoxico-Origanetum virentis and Pimpinello-Origanetum viretis (Origanion virentis).- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
