Virtualization of pliocene sites in the Huelva province: valuating the paleontological heritage in differentiate educative settings I
El patrimonio paleontológico del Plioceno de la provincia de Huelva es uno
de los más importantes de España y referente europeo de moluscos de este
período. Sin embargo, no existe un inventario de catalogación básica de los
principales yacimientos ni de los principales grupos fósiles presentes, así como
de su importancia como patrimonio natural. El presente trabajo pretende rellenar
este notable vacío con una proyección tanto hacia materias preuniversitarias
como universitarias, así como hacia posibles instituciones y corporaciones
públicas susceptibles de utilizarlo en sus planes de ordenación. Por otro lado, se
pretende que actúe como mecanismo de interconexión entre titulaciones con bajo
número de alumnos de nuevo ingreso y los centros de Bachillerato, de forma que
incentive una posible elección de estos Grados por los alumnos de las opciones
científico-tecnológicas. También puede ser interesante para captar egresados
hacia Másteres Oficiales en Patrimonio Histórico y Natural. En este sentido, se
ha realizado un DVD documental sobre el patrimonio paleontológico del
Plioceno de la provincia de Huelva, concretamente de las formaciones “Arenas
de Huelva” y “Arenas de Bonares” desarrolladas en ambientes marinos someros
y costeros durante la última etapa de evolución neógena de la cuenca. Este
documental incluye una visión de conjunto de los principales yacimientos fósiles
de esta edad, así como una explicación de la evolución paleogeográfica de
nuestra provincia y los organismos que la han caracterizado en los últimos
millones de años. Esta aportación es aplicable en el trabajo de campo de varios
Grados y Posgrados universitarios y de fácil uso como material didáctico en
diversas asignaturas de E.S.O. y Bachillerato. Este trabajo se ha realizado en el
marco del proyecto de innovación docente (PID nº 10050) de la Universidad de
Huelva.The paleontological heritage from the Neogene in the province of Huelva is
one of the most important in Spain and it is considered a European reference site
for the mollusk fossil record from this period. However, there are not basic
inventories neither for the main sites nor the major fossil groups. Furthermore,
no inventories exist about their natural heritage importance. This work aims to
fill this significant gap for both pre-university and university levels, as well as to
public institutions and corporations that may use it in their management plans. In
addition, it is intended to act as an linking mechanism between university
degrees with low number of first-year students and high school centres, in order
to encourage a possible choice of these Bachelor’s degrees by scientific and
technological students. It may also be interesting to catch the attention of
graduates for Official Masters in Historical and Natural Heritage. In this sense, a
DVD-documentary has been made about the paleontological heritage from the
Pliocene in the province of Huelva, specifically from the “Arenas de Huelva”
and “Arenas de Bonares” formations. These units were developed in shallow
marine and coastal environments during the last stage of the Neogene evolution
in the Guadalquivir Basin. This documental includes an overview of main marine
fossil sites from this age and a brief explanation of the palaeogeographic
evolution of the Huelva province during the last million of years. This
contribution is useful for the fieldwork at Bachelor and Master Degree level and
it is easy to use as teaching materials in different ESO (Obligatory Secondary
Teaching) and High School subjects. This work has been support for an
Innovation in Teaching Project (PID No. 10050) of the Huelva University
Unidades litológicas del Neógeno en el extremo oeste de la Cuenca del Guadalquivir y su correlación con el sondeo Huelva-1 (Huelva - España)
A detailed surveying and a new geological map of the sheet at 1:50.000 number 999/1016 (Huelva - Los Caños), located at the west end of the Guadalquivir Basin, has been carried out. This data allows us to propose a new organization of the lithological units present at the west side of the Odiel River. These units include all the sedimentary record in this sector of the Guadalquivir Basin, ranging from Tortonian to Pliocene, but with shallower and coarser facies that are only present in this part of the basin. This fact is due to the location of the area, probably less subsiding due to a longer distance from Betic-Rif orogen. The lithological units are described concisely and a correlation with the core of the Huelva-1 borehole and with the outcrops of Huelva – Palos de la Frontera area is also proposed. The units are organized in a stack of sequences with a progradational pattern, typical of a basin margin, and highlighting a gradual reduction of the accommodation space in the late Messinian and during the Pliocene.Se ha realizado un reconocimiento detallado y un nuevo mapa geológico de la hoja a 1: 50.000 número
999/1016 (Huelva - Los Caños), situada en el extremo oeste de la Cuenca del Guadalquivir. Estos datos nos han
permitido proponer una nueva organización de las unidades litológicas presentes en el lado oeste del río Odiel. Estas
unidades incluyen el registro sedimentario completo de este sector de la Cuenca del Guadalquivir, que va desde
Tortoniense al Plioceno, pero mostrando unas facies más someras y gruesas que solo están presentes en esta parte de
la cuenca. Este hecho se debe a la ubicación de la zona, probablemente menos subsidente debido a su mayor distancia
con respecto al orógeno Bético-Rifeño. Las unidades litológicas se describen de forma concisa y se propone también su
correlación con el testigo del sondeo Huelva-1 y los afloramientos de la zona de Huelva - Palos de la Frontera. Las
unidades litológicas se organizan formando un apilamiento de secuencias con un patrón progradacional, típico de un
borde de cuenca, y ponen de manifiesto una reducción gradual del espacio de acomodación a finales del Messiniense y

Interactions between species in coastal lagoons: Predation on recent brackish ostracod populations of the Lagoon of Venice (NE Italy).
This chapter analyzes the first evidences of predation observed on recent brackishostracod populations of the Lagoon of Venice. The study of ninety-nine samples andalmost 1300 specimens allowed extraction of 12 bored valves. The bioerosion structures(Oichnus simplex Bromley) are concentrated in the central area of the valves. Boreholediameter shows a negative but not significant correlation with the dimensions of thepredated valves, whereas the number of bored shells is significantly correlated with theostracod density. Predation affects the most abundant species of this environment (mainlyadults and the last juvenile instars)
Group and call effect in achieving success in a subject: Analyses of the "Biology and Botany" whole life in the E.U.I.T.A. (University of Seville)
La Biología y la Botánica son dos materias fundamentales en la formación de
un ingeniero técnico agrícola. Sus contenidos se han ofrecido a veces en asignaturas
independientes y, en otras ocasiones como la que nos ocupa, en una sola
asignatura. Por otra parte, siempre se ha mirado con interés, e incluso preocupación,
el efecto de la variable grupo, de forma independiente o relacionándola con
su distribución en turnos de mañana o tarde, así como la importancia de la convocatoria
(en los distintos momentos a lo largo del curso académico) en la que el
alumno consigue superar la asignatura.
Aquí presentamos los resultados en la consecución de objetivos por parte de
los alumnos y, por ende, de los profesores y de la Universidad de Sevilla a lo largo
de la totalidad de la vida de la asignatura "Biología y Botánica" dentro del
plan de estudios 2003/04 para tres titulaciones simultáneas, desde su comienzo
en el curso 2003/04 hasta su extinción en el curso 2009/10, de la E.U.I.T.A. (Escuela
Universitaria de Ingeniería Técnica Agrícola) de la Universidad de Sevilla.
Además se consideran convocatorias pertenecientes al período de extinción añadido.
Los análisis toman en cuenta además el éxito en la superación de la asignatura
tanto de forma cualitativa (aprobado o suspenso de la evaluación a la que el
alumno se ha sometido) como cuantitativa (nota conseguida).
Las conclusiones obtenidas permiten mirar los resultados y la consecución de
objetivos, así como una potencial toma de decisiones para el futuro, basándose
en un marco temporal amplio y objetivo.Biology and Botany are two critical issues in the formation of a technical
agricultural engineer. Their topics are sometimes offered in separate subjects
and, at other times as here, within a single one. Besides, it has always been
considered with interest, and even concern, the effect of the variable group,
independently or in relation to their distribution in the morning or afternoon
turns, and the importance of the call (at different times during the academic year)
at which the student gets to pass the subject.
Here we present the results in the achievement of objectives by students, and
therefore teachers and the University of Seville, along the entire life of the
subject "Biology and Botany" within the teaching 2003/04 plan for three
simultaneous academic programs, from its start in the course 2003/04 to its
extinction in the course 2009/10, in the E.U.I.T.A. (University School of
Technical Agricultural Engineering) of the University of Seville. Calls belonging
to the period of extinction are also considered. Analyses are both qualitative,
based on having success in passing the subject or not, and quantitative (mark
scored).
Obtained conclusions let us see the results and the achievement of objectives,
as well as a potential decision-making for the future, with a base on a
comprehensive and objective frame

The European Solar Telescope
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design combines the knowledge and expertise gathered by the European solar physics community during the construction and operation of state-of-the-art solar telescopes operating in visible and near-infrared wavelengths: the Swedish 1m Solar Telescope, the German Vacuum Tower Telescope and GREGOR, the French Télescope Héliographique pour l'Étude du Magnétisme et des Instabilités Solaires, and the Dutch Open Telescope. With its 4.2 m primary mirror and an open configuration, EST will become the most powerful European ground-based facility to study the Sun in the coming decades in the visible and near-infrared bands. EST uses the most innovative technological advances: the first adaptive secondary mirror ever used in a solar telescope, a complex multi-conjugate adaptive optics with deformable mirrors that form part of the optical design in a natural way, a polarimetrically compensated telescope design that eliminates the complex temporal variation and wavelength dependence of the telescope Mueller matrix, and an instrument suite containing several (etalon-based) tunable imaging spectropolarimeters and several integral field unit spectropolarimeters. This publication summarises some fundamental science questions that can be addressed with the telescope, together with a complete description of its major subsystems
La ostracofauna de los sedimentos litorales del NE de Italia. II: la cuenca de Chioggia (Laguna de Venecia).
A scarce ostracofaune was found in the southern basin of the Venice lagoon. Nine species were recognized, well distributed in the inner channel mouths (Cyprideis torosa and Loxoconcha elliptica), external border of the "barenes" (C. torosa) and near the Chioggia harbour (C. torosa and Pontocythere turbida). The morphological features and distribution of P. turbida and Pontocythere elongata, a atlantic species, were compared
Freshwater ostracods as environmental tracers
This paper revises the response of freshwater ostracods to different
environmental conditions and anthropogenic impacts, with a worldwide
overview of the potential use of these microcrustaceans as
bioindicators and several examples of applications in different
scenarios. The development of either a single species or an ostracod
assemblage is influenced by physical-chemical properties of waters
(salinity, temperature, pH, dissolved oxygen), hydraulic conditions,
bottom grain sizes or sedimentation rates. In addition to population
and community changes, morphological and geochemical changes can also
be detected in the ostracod carapace, which serves as a tracer of the
water quality. All these features permit to delimit the spatial effects
of urban sewages, mining effluents, agricultural wastes, watershed
deforestation or road building. These data are the basis for the
palaeoenvironmental reconstruction of cores, with an interesting
application to archaeology. In addition, favourable results of recently
developed bioassays, coupled with an important variability of local
assemblages under changing conditions in both waters and sediments,
suggest that these microcrustaceans may included between the most
promising sentinels groups in freshwater areas. These microcrustaceans
show high sensitivity to pesticides, herbicides, heavy metal pollution
and oil inputs
