New insights on patterns of genetic admixture and phylogeographic history in Iberian high mountain populations of midwife toads.

open access: yesPLoS ONE, 2022
Multiple Quaternary glacial refugia in the Iberian Peninsula, commonly known as "refugia within refugia", allowed diverging populations to come into contact and admix, potentially boosting substantial mito-nuclear discordances. In this study, we employ a

Pitch production during the Roman period: an intensive mountain industry for a globalised economy? [PDF]

open access: yes, 2013
The authors’ research project in the Pyrenees mountains has located and excavated Roman kilns for producing pitch from pine resin. Their investigations reveal a whole sustainable industry, integrated into the local environmental cycle, supplying pitch to

Population dependent behavioral responses among color morphs of European wall lizard (Podarcis muralis)?

open access: yesActa Herpetologica, 2023
Color polymorphisms are common across reptile species and are frequently correlated with variation in behavior and other functional traits. Here, we tested whether the ventral color morphs (yellow, orange and white pure, as well as yellow-orange and ...

Stand-level drivers of tree-species diversification in Mediterranean pine forests after abandonment of traditional practices [PDF]

open access: yes, 2015
The progressive abandonment of traditional forest management over the last few decades has led to significant densification processes in most Mediterranean pine stands.

Interferometric SAR monitoring of the Vallcebre landslide (Spain) using corner reflectors [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2013
This paper describes the deformation monitoring of the Vallcebre landslide (Eastern Pyrenees, Spain) using the Differential Interferometric Synthetic Aperture Radar (DInSAR) technique and corner reflectors (CRs). The fundamental aspects of this satellite-

Long-term forest-line dynamics in the French Pyrenees: an accelerating upward shift related to forest context, global warming and pastoral abandonment [PDF]

open access: yesBiogeosciences
Worldwide, the upper forest line has climbed over the past decades, shaping mountain landscapes in response to global changes. In European mountains, this recent trend is a continuation of the forest transition initiated in the mid-19th century, when ...

Description and analysis of the debris flows occurred during 2008 in the Eastern Pyrenees [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2010
Rainfall-triggered landslides taking place in the Spanish Eastern Pyrenees have usually been analysed on a regional scale. Most research focussed either on terrain susceptibility or on the characteristics of the critical rainfall, neglecting a detailed ...
