Se presentan los datos palinológicos, procedentes de dos depósitos de origen fluvio-lacustre, localizados en la cuenca alta (Redueña) y media (Valdecarros), del valle del río Jarama (Madrid). En ambas secuencias, la abundancia de industria lítica y de restos óseos de macro y micromamíferos, evidencian que se trata de yacimientos relacionados con campamentos de sociedades cazadoras. Dichos campamentos, funcionales durante el Pleistoceno Medio (500 a 130 ka), bajo un clima generalizado de carácter cálido, eran estacionales asociados a las zonas de rib era de lo s río s p o r tratarse de áreas con excelentes recursos Bajo esta perspectiva el objetivo principal, es recrear el contexto paleoambiental, en el que se desarrollaron los citados campamentos y establecer las similitudes y diferencias que la posición geográfica, imprime sobre la vegetación. Palynological data are presented from two deposits offluvio-lacustrine origin, located in the upper basin (Redueha) and average (Valdecarros), River Jarama valley (Madrid). In both sequences, the abundance of stone tools, as well as in bone remains, both macro and small mammals suggests, that these deposits are related to camp sof hunter-gatherer societies. These camps, functional during the Middle Pleistocene (500 to 130 ka), under a climate generally warm, we reseasonal, associated with river banks, being are as with excellent resources. This perspective arises, as main objective, to recreate the paleoenvironmental context, in which the aforementioned camps were developed as well as to establish the similarities and differences that the geographic position, prints on the vegetation

Los datos polínicos, procedentes del Abrigo de Navalmaíllo (Pinilla del Valle,Madrid), constituyen un registro excepcional, al ser pioneros en cuanto a su resolución temporal para la zona de estudio. Las dataciones de la secuencia (71.685 ± 5.082 – 77.230 ± 6.016), aportan información paleoambiental para el Pleistoceno Superior, en un área, donde los yacimientos y depósitos naturales son formaciones relativamente recientes, con un registro generalmente a partir los últimos 3000-4000 años.Además, dado que en dicho abrigo se ha constatado, tanto desde el punto de vista paleontológico como arqueológico, una intensa ocupación humana, la composición y los cambios en el cortejo florístico, cobran un interés especial revelando las fluctuaciones climáticas, a través del tránsito desde paisajes boscosos, de índole mediterráneo, a espacios abiertos de carácter seco y fresco. Además el espectro polínico es capaz de explicar la falta del registro antracológico, y puede ser interpretado bajo la perspectiva de la potencialidad de los recursos que la cubierta vegetal ofreció a la comunidad humana, de neandertales, asentada en el territorio, Pollen data from the Navalmaíllo rockshelter (Pinilla del Valle, Madrid), constitute an exceptional record, being pioneers in terms of its temporal resolution for the study area. Dating of the sequence (71,685 ± 5,082 – 77,230 ± 6,016), provide information Upper Pleistocene period, in an area where the archaeological sites and natural deposits are relatively recent formations (around usually from 3000-4000 years ago). In addition, given that the coat you have shown, both from the paleontological and archaeological point of view, intense human occupation, the composition and changes in the floristic cortege, charge special interest revealing climatic fluctuations through the transit from forested landscapes of Mediterranean nature, open spaces of dry and fresh character.Also the pollen spectrum is able to explain the lack of the rich record, and it can be interpreted under the perspective of the potential of the resources offered by the vegetation cover to the human community, Neanderthals, settled in the territory

El asentamiento celtibérico de Peña Moñuz se ubica en el entorno de La Dehesa (Olmeda de Cobeta, Guadalajara), uno de los mejores entornos de tipo adehesado preservados en toda la cuenca alta del Tajo. La zona, de rico patrimonio arqueológico y etnográfico permite seguir con cierto detalle la evolución de la ocupación humana en el entorno y su relación con el medio natural. Con el apoyo de los aspectos culturales, se definen los procesos de utilización del medio físico a partir del análisis polínico. Los resultados evidencian que la ocupación, desde la edad del hierro (celtíberos), está centrada fundamentalmente en la ganadería, y en menor medida en la agricultura, siendo ambas determinantes en los procesos del cambio paisajístico The Peña Moñuz Celtiberian settlement is located in the vicinity of La Dehesa (Olmeda de Cobeta, Guadalajara), one of the best preserved Dehesa type environments throughout the upper basin of the Tagus river. The area is rich archaeological and ethnographic Heritage sites allowing to tracing the evolution of human occupation of the area, and their relationship with the environment. With the support of the cultural evidences, past land uses are defined from pollen analysis. The results show that the occupation from the Iron Age (Celts), was focused mainly on livestock, and to a lesser extent in agriculture. Both of determinaed the processes of landscape change

Pollen and non-pollen palynomorphs analysis of upper Pleistocene and Holocene Buena Pinta cave sediments of the in the Calvero de la Higuera (Pinilla del Valle. Madrid) archaeopaleontological site has been conducted. The results shows a vegetation dynamics from the pollen diagrams can be correlated with the vegetation progressive evolution of an open landscape as adaptation to the installation of hot and dry character climatic conditions. Nivel-3 of sequence is dated by OSL is 63.451±5.509 years no cal.; radiocarbon dating of 14C locates its development, before 4.940 ± 40 years BP

Congreso Geológico de España (7º. 2008. Las Palmas de Gran Canaria). - Texto en español con resumen y palabras claves en español e inglés, En el presente trabajo se presentan los datos polínicos de los primeros 50 cm. del sondeo PVC 4.1 localizado a la derecha del río Cigüela, dentro del Parque Nacional de las Tablas de Daimiel, con el fin de poder establecer la reconstrucción paleoambiental y paleoclimática así como la influencia del hombre en este ecosistema. Se han podido identificar dos importantes periodos de impactos sobre el humedal, el denominado periodo natural y el antrópico. Durante la primera fase de la secuencia (natural) los cambios detectados en el ecosistema fueron debidos fundamentalmente a variaciones climáticas ante las cuales la vegetación tiene tendencia a la recuperación. Sin embargo, los cambios en el paisaje debidos a la actividad antrópica, especialmente la desecación y la sobreexplotación rompieron el ciclo natural, de manera que el ecosistema no ha sido capaz de recuperarse a pesar de los intentos para evitar la pérdida de superficie inundada. = This article presents polinical data from the first 50cm of the PVC 4.1 core, located on the right bank of the river Cigüela, on Parque Nacional de las Tablas de Daimiel, with the aim of establishing the paleoenviromental and paleoclimatic reconstruction, as well as human influence on the site. Two important periods with significant impact on soil moisture have been identified: the natural and the anthropic. During the first stage of the sequence (natural), changes detected on the ecosystem were due mainly to climatic variations. After those changes vegetation cover tend to natural recovery. However, changes due to anthropic activity, mainly desiccation and overexploitation, broke the natural cycle, to the extent that the ecosystem has not been able to recover on spite of several attempts made to prevent the loss of flooded surface., Departamento de Geología, Universidad de Alcalá de Henares, España, Dirección de Geología y Geofísica, Instituto Geológico y Minero de España, España, Departamento de Estratigrafía, Universidad Complutense de Madrid, España

Reunión Nacional sobre Cuaternario (12ª. 2007. Ávila) . - Resumen. - Texto en español con resumen en inglés y palabras claves en español e inglés, This contribution summarizes the main vegetation changes during the last 3000 years reconstructed from the pollen record of the PVC 4.2 core located in the west margin of the Cigüela River (Las Tablas de Daimiel National Park). Some periods of noticeable impacts on the wetland are identified, some during periods of little human impact and others clearly of anthropic origin. At the beginning of the sequence, the ecological changes were controlled by the climate variability, and the system showed a natural recovery mechanism. The later intense human-made disturbances abruptly distrubed the natural recovery mechanism making difficult the regeneration of the ecosystem., Departamento de Geología, Universidad de Alcalá de Henares, España, Dirección de Geología y Geofísica, Instituto Geológico y Minero de España, España, Departamento de Estratigrafía, Universidad Complutense de Madrid, España
