Integrating technical and scientific approaches to restore rupicolous plants threatened by climbing activities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Rocky habitats are fragile ecosystems that host unique biodiversity and are increasingly threatened by the rapid expansion of outdoor climbing. In the northwestern region of El Bierzo (Spain), populations of the endemic rupicolous species Petrocoptis grandiflora and P. pyrenaica ssp. viscosa have experienced severe declines linked

Epoxy Clerodane Diterpene Attenuates the Differentiated Adipocyte Hypertrophy and Enhances Mitochondrial Metabolism

open access: yesChemistryOpen, Volume 15, Issue 7, July 2026.
Epoxy Clerodane Diterpene (ECD) significantly reduces adipocyte hypertrophy and lipid accumulation in human mesenchymal stem cell (hMSC)‐derived adipocytes. ECD improves mitochondrial membrane potential (ΔΨm), increases thermogenic regulators (UCP‐1, PPARγC1α), decreases adipogenic markers (C/EBPα, PPARγ), and reduces inflammatory mediators (TNF‐α, NF ...

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Cultivated Vegetation Shapes Diversity and Stability of Spontaneous Herbaceous Communities in Residential Green Spaces

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Cultivated vegetation shapes the diversity and stability of spontaneous herbaceous communities in residential green spaces, with effects varying across vegetation types. Spontaneous communities were dominated by occasional species, and community stability and dissimilarity were more closely associated with species frequency structure than with overall ...

Efficient Automatic Pollen Recognition From Fossil Pollen Samples: A High‐Resolution Example Record From Palaeolake Kieshofer Moor, Northeastern Germany

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We applied the two‐stage, AI‐based TOFSI approach to test automatic pollen recognition with fossil pollen samples. The algorithm performs very well for all major pollen types and other non‐pollen object classes, suggesting that such tools have the potential to substantially increase the efficiency of pollen analysis.

Doświadczenia nad kiełkowaniem ziaren pyłkowych na zalążkach kilku przedstawicieli z rodziny Caryophyllaceae i Cruciferae w warunkach hodowli in vitro [Pollen grains germination on ovules of some species of the Caryophyllaceae and Cruciferae families in the in vitro culture]

open access: yesActa Societatis Botanicorum Poloniae, 2015
The ovules of several species of the Caryophyllaceae and Cruciferae families were pollinated in the in vitro culture. Stigmas of the same species were pollinated in natural conditions.

A revision of Cerdia (Caryophyllaceae) [PDF]

open access: yesBotanical Journal of the Linnean Society, 2006
Cerdia is a poorly understood genus of minute cushiony plants endemic to Mexico that is traditionally placed in subfamily Paronychioideae, tribe Polycarpeae (Caryophyllaceae). Morphological observations and phylogenetic analysis of ITS DNA sequences were carried out to determine the number of species, heretofore controversial, that constitute the genus
