Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

Archaeometry, EarlyView.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Simonsenia aveniformis sp nov (Bacillariophyceae), molecular phylogeny and systematics of the genus, and a new type of canal raphe system [PDF]

, 2015
The genus Simonsenia is reviewed and S. aveniformis described as new for science by light and electron microscopy. The new species originated from estuarine environments in southern Iberia (Atlantic coast) and was isolated into culture. In LM, Simonsenia

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Morphological response of the saltmarsh habitats of the Guadiana estuary due to flow regulation and sea-level rise [PDF]

, 2016
In the context of rapid sea-level rise in the 21st century, the reduction of fluvial sediment supply due to the regulation of river discharge represents a major challenge for the management of estuarine ecosystems.

A multidisciplinary study on the location of Roman sites in the southern sub‐plateau of the Iberian Peninsula

Archaeometry, Volume 67, Issue 5, Page 1373-1390, October 2025.
Abstract Architectural and engineering elements of the Roman civilization constitute an important cultural heritage. Nevertheless, not all ancient Roman cities and the roads connecting them have been found, mainly because classical geographical sources show a significant lack of precision.

Estuarine Mapping and Eco-Geomorphological Characterization for Potential Application in Conservation and Management: Three Study Cases along the Iberian Coast

Applied Sciences, 2020
Geomorphological changes in recent decades in three estuaries along the Iberian coast were analysed using aerial orthophotographs. A hierarchical classification scheme, based on a literature review representing 26 estuarine eco-geomorphological features ...

Fish-based groups for ecological assessment in rivers: the importance of environmental drivers on taxonomic and functional traits of fish Assemblages [PDF]

, 2012
The use of river-types is of practical value, serving as groups for which assessment procedures can be developed and applied. An abiotic typology was set by the Portuguese Water Agency, mainly based on 6 major morphoclimatic regions.

River metabolism regimes across large environmental gradients

Limnology and Oceanography, Volume 70, Issue 9, Page 2718-2732, September 2025.
Abstract Rivers process up to half of the terrestrial organic carbon before it reaches the oceans, playing an essential role in the global carbon cycle. However, little is known of the seasonal and regional patterns of riverine biological activity as most river ecosystem metabolism studies have been carried out at short spatial and temporal scales.

Learning contexts of the others: Identity building processesin southern Europe

European Journal for Research on the Education and Learning of Adults, 2011
The frontier between the south of Spain and Portugal is established by the river Guadiana. Lying next to the sea, the cities of Ayamonte (Spain) and Vila Real de SantoAntónio (Portugal) face each other on opposite banks of the river.
