Seasonality and cyclic tendency of mortality in a Pyrenean population

open access: yesPirineos: Revista de Ecología de Montaña, 1990
[es] Las características de la mortalidad Influyen decisivamente en la estructura demográfica de las poblaciones, regida por diferentes factores: internos (rasgos específicos genéticos y culturales), externos (características del ecosistema) e ...

Increases in species richness cause decreases in phylogenetic diversity in Mediterranean and Temperate plant assemblages

open access: yesEcology, Volume 107, Issue 4, April 2026.
Abstract The relationship between taxonomic and phylogenetic diversities remains underexplored. Our goal was to determine whether a causal link exists between species richness and phylogenetic diversity and to determine the direction of this relationship.

Species delimitation among Primula hirsuta and related taxa (Primulaceae) confirms the existence of cryptic species in the Europeans Alps

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract Primula sect. Auricula is the largest plant clade endemic to Western European mountains and hence an important model to study speciation in mountain plants. Within this section, a clade of closely related and largely cryptic taxa, with P. hirsuta and P. pedemontana as its most prominent members, has remained taxonomically challenging. New taxa

Small RNAs regulation and genomic harmony: insights into allopolyploid evolution in marsh orchids (Dactylorhiza)

open access: yesNew Phytologist, Volume 250, Issue 1, Page 648-660, April 2026.
Summary Hybridization and polyploidy are major drivers of plant diversification, often accompanied by shifts in gene expression and genome composition. Small RNAs (smRNAs) are thought to influence such genomic changes, particularly through their interactions with transposable elements (TEs).

3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

open access: yesTerra Nova, Volume 38, Issue 2, Page 130-140, April 2026.
ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

From detailed to summary models of the crop-soil system for larger scale applications [PDF]

open access: yes, 2008
Crop growth models developed at field level are increasingly used in larger scale studies often in combination with other models to explore management options at the whole-farm scale or for integrated assessment at regional level (e.g.
