Snails in the limestone caves of the Bohemian Forest foothills (SW-Bohemia)

open access: yes, 2003
In ten explored limestone caves of the Bohemian Forest foothills, 23 snail species were found. The records were partly published elsewhere (DVOŘÁK 1999). O. cellarius, O. glaber, H. pomatia, L. cinereoniger, and H. lapicida are the most typical and most frequent species (see Table 1). The occurrence of the majority of other species in the caves is more

Vegetation cycles in a disturbed sequence around the Cobb-Mountain subchron in Catalonia [PDF]

open access: yes, 2008
A 52 m-long lacustrine sequence has been recovered from the basin of Bòbila-Ordis, near Banyoles (N-E Spain). The presence of Early Biharian rodent teeth (Early Pleistocene) and of a c.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Conservation status assessments of species-rich tropical taxa in the face of data availability limitations: insights from Sulawesi Begonia

open access: yesScientific Reports
Species conservation assessments using the criteria outlined by the International Union for the Conservation of Nature Red List can be compromised by limited data availability. Species-rich tropical plant taxa with numerous microendemics are particularly

The effect of early diagenetic processes on the quantification of fossil micrometeorite abundance and flux in the geological record

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

Mixing oak and pine trees in Mediterranean forests increases aboveground hydraulic dysfunctions

open access: yesPlant Biology, EarlyView.
Mixing oak and pine trees enhances hydraulic impairments of all species, although diversity can mitigate drought stress during extended drought periods. Abstract Increasing tree species diversity in Mediterranean forests could reduce drought‐induced hydraulic impairments through improved microclimate and reduced competition for water.

Linking sap flow and tree water deficit in an unmanaged, mixed beech forest during the summer drought 2022

open access: yesPlant Biology, EarlyView.
Sap flow and reversible stem shrinkage upon water depletion are strongly correlated under extreme drought conditions, but they respond differently to drought and cannot be used interchangeably when assessing tree response to drought. Abstract Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of ...

Age and origin of closed depressions in the Paris Basin: A majority of marl pits dug since the Neolithic period?

open access: yesGeoderma
Marling (limestone alkaline amendment) agrarian practices have a plurimillennial influence on soil pH and on soil-associated ecosystems. Although the earliest written records in Europe date back to antiquity, the origin of this agrarian practice is not ...

Root water uptake depth in temperate forest trees: species‐specific patterns shaped by neighbourhood and environment

open access: yesPlant Biology, EarlyView.
Root water uptake strategies vary among temperate tree species (European beech, Douglas fir, and Norway spruce), with beech–conifer mixtures altering water uptake depths, while site conditions and temporal dynamics further shape the contribution of different soil depths to water supply.
