Los primeros depredadores en Navarra: estado de la cuestión y nuevas aportaciones

Abstract

Se expone un estado de la cuestión sobre el Paleolítico Inferior en Navarra con los datos disponibles hasta 1993. En la segunda parte se aporta un estudio preliminar de los nuevos hallazgos en la Cuenca de Pamplona, que pueden ser incluidos dentro del Achelense.

Complexo arqueológico Dos Perdigões. Reguengos de Monsaraz, (Portugal): EL SECTOR L1: Actuaciones arqueológicas de la Universidad de Málaga (2008-2016)

“…Dicha imagen, aun siendo de gran valor, resultaba insuficiente a la hora de proporcionar información más detallada con vistas a realizar lecturas más completas. Por tal motivo, y dado el éxito que el empleo de prospecciones geofísicas estaba alcanzando en este tipo de yacimientos (Delibes et al 2010;García Gazólaz y Sesma 2001;Gibson et al 2001;Hasek y Kovarník 1999), decidimos iniciar nuestras actuaciones abordando, novedosamente, estas metodologías en Perdigões1.…”

Excavando en los recuerdos

“…Éste último se ha convertido en el paradigma para explicar la Edad del Bronce pleno y sus perduraciones en la zona (Sesma, J. 1988;1993b;Sesma, J. y García, M a L., 19911994ay 1994b.…”

Towards the integrated management of the Texas citrus mite Eutetranychus banksi (Acari: Tetranychidae) in Spain

“…Phytoseiids move to the upper side of leaves on the periphery of the canopy and also increase the movement to the fruit to feed on E. banksi, since, in the absence of its prey, do not usually inhabit the upper side of peripheral leaves and fruit. Within-plant daily migrations seem to be a common behaviour in phytoseiids, which remain sheltered during the day inside the tree canopy to avoid unfavourable climatic conditions and migrate at dusk to feed on spider mites outside the tree canopy during the night, coming back inside at dawn (García-Marí et al 1985;Onzo et al 2003Onzo et al , 2010. Surveys were carried out all year-round during sunlight hours, and therefore we cannot corroborate this hypothesis.…”

“…Phytoseiids spend most of their lifetime inside the canopy; however, they are moving continuously while foraging for prey or other foods (Sabelis 1985). The foraging behaviour may depend not only upon prey availability, but also on abiotic factors such as relative humidity, temperature, and light intensity, being aggregated on the old leaves during day and moving to the periphery of the canopy during the night searching for spider mites and showing a random aggregation pattern on leaves (García-Marí et al 1985;Villanueva and Childers 2005).…”

“…To avoid adverse climatic conditions during the day, such as high temperatures, low relative humidity, rain, or high ultraviolet radiation, phytoseiids remain sheltered and move during the night to forage (Onzo et al 2003(Onzo et al , 2010. Daily migrations on citrus phytoseiids have been described for E. stipulatus on sweet oranges (García-Marí et al 1985). According to these authors, during sunlight hours, when temperature and humidity conditions are more adverse, the phytoseiids are mainly found sheltering on the underside of the leaves inside the canopy, with an aggregate distribution.…”
