“…In order to limit the number of environmental variables that may affect soil WR, a site at Doñana National Park was selected, approximately at coordinates 37°7ʹ27ʺN 6°30ʹ5ʺW, with sandy soils showing relative spatial homogeneity and properties, under different vegetation covers: cork oak ( Quercus suber , QS), eagle fern ( Pteridium aquilinum , PA), pine ( Pinus pinea , PP) and rockrose ( Halimium halimifolium , HH). Doñana National Park is located in the southwestern coast of Spain under a Mediterranean climate with a strong oceanic influence, which favours mild temperatures, and relatively high humidity and rainfall compared with inland (Siljeström & Clemente, ). Mean annual rainfall is 830 mm with 77% of precipitation occurring between October and March and a mean air temperature of 16·9 °C.…”

The relationship between soil organic matter (SOM) content and organic molecular assemblages (n‐alkane/alkenes pairs and n‐fatty acids) with soil water repellency (WR) in different sieve fractions (1–2, 0·25–1, 0·05–0·5 and <0·05 mm) was studied in sandy soils from the Doñana National Park (SW Spain) under four vegetation species: Quercus suber (QS), Pteridium aquilinum (PA), Pinus pinea (PP) and Halimium halimifolium (HH). The severity of soil WR [assessed according to the water drop penetration time (WDPT) test] was ordered according to the sequence QS > PA > PP > HH. A positive correlation was found between soil WR from each sieve fraction and SOM content. Most severe soil WR was detected in QS for all sieve fractions, followed by the finer fractions (<0·05 mm) from PA, PP and HH samples. The finer fraction had the highest SOM content, ranging between 20·9% (PP) and 46·9% (QS). Coarser PA, PP and HH soil fractions (1–2 mm) showed the highest long‐chain‐even C numbered fatty acids in the order PP > PA > HH. A significant correlation was observed between SOM content and the severity of soil WR in QS samples and finer fractions of soil under other vegetation (PA, PP and HH). Coarser fractions (1–2 mm) from PP, PA and HH 1–2 mm sieve fractions showed high severity of WR and relatively low SOM contents that could be explained by a low degree of evolution of the organic residues as seen by analytical pyrolysis, that is, higher alkane/alkene carbon preference index values and the presence of a higher diversity of fatty acid structures.

A multi-proxy palaeoenvironmental study (pollen, non-pollen palynomorphs, charcoal particles, mollusk macrofauna) of coastal marshland in Doñana National Park (southwestern Iberian Peninsula) was undertaken to trace environmental change, human activities related to woodland clearance, and past land-use during the mid-late Holocene (~ 5000-2800 cal BP). The results of this study are combined with archaeological data from the Copper and Bronze Ages and are subsequently compared with those of similar research carried out at the south-westernmost part of Europe with the aim of discerning regional differences or similarities. Our research has allowed us to recognize climate changes and four extreme wave events in the Guadalquivir paleoestuary, which might have contributed to both the cultural change that is observed in the archaeological record at the end of the Chalcolithic and the subsequent population decline during much of the Bronze Age.

“…The study was performed in the Doñana National Park in south-western Spain (38°13′ N, 48°10′ W). The site is located approximately km from the Atlantic Ocean on sandy soils derived from a dune field.The parent material of the studied soil is eolian sandy sediment from Holocene covering gravels and sandy sediments from Pliocene-Pleistocene, constituting a system of stabilized dunes (Siljeström & Clement, 1990). The main soil types are Typic Xeropsamment (dune tops), Aquic Xeropsamment (dune slopes), and Humaqueptic Psammaquent (inter-dune depressions) (Siljeström et al 1994).…”

This study reports the relationship between the diversity and functioning of fungal and bacterial soil communities with vegetation in Mediterranean woodland that experienced severe die-off after a drought episode. Terminal restriction fragment length polymorfism (TRFLP) was used to describe microbial community structure and diversity five years after the episode in different habitats (Juniperus woodland, shrubland, grassland), when the vegetation had not yet recovered. Vegetation diversity was positively related to TRF bacterial richness under unaffected canopies and was higher in diverse grassland. Fungal TRF richness correlated with vegetation type, being greater in Juniperus woodland. Microbial respiration increased in grassland, whereas microbial biomass, estimated from soil substrate-induced respiration (SIR), decreased with bacterial diversity. Die-off increased bacterial richness and changed bacterial composition, particularly in Juniperus woodland, where herbaceous species increased, while fungal diversity was reduced in Juniperus woodland. Die-off increased microbial respiration rates. The impact on vegetation from extreme weather episodes spread to microbial communities by modifying vegetation composition and litter quantity and quality, particularly as a result of the increase in herbaceous species. Our results suggest that climate-induced die-off triggers significant cascade effects on soil microbial communities, which may in turn further influence ecosystem C dynamics.
