Identifying knowledge gaps in a biodiversity database and their spatial determinants

Open-access biodiversity databases are valuable resources in the structuring and accessibility of species occurrence data. By compiling different data sources, they reveal the uneven spatial distribution of knowledge, with certain areas and taxonomic groups being better represent...

Widespread hybridization in sympatric populations of allis shad Alosa alosa (L.1758) and twaite shad Alosa fallax (Lacépède 1803): A transnational perspective for conservation and management

Abstract The dynamics of hybridization between co‐occurring species in environments that have been modified by anthropogenic activities are important for generating new understandings of how species respond to disturbance and to support conservation management. Accordingly, the p...

Multiplex species-specific real-time PCR assays for the detection of European Armillaria spp. and Desarmillaria spp. in different environmental substrates

Armillaria root rot, caused by basidiomycete fungi of the genera Armillaria and Desarmillaria , affects numerous agronomic crops and forest trees worldwide. In Europe, seven species have been described, namely Armillaria mellea , A. ostoyae , A. gallica , A. borealis , A. cepisti...

Cascading effects of insufficient seed cold stratification across early life-stages in three temperate trees: impaired phenology and reduced seedling fitness under climate warming

BACKGROUND AND AIMS: Global warming is shortening winters in temperate ecosystems, limiting cold stratification for seeds with physiological dormancy (PD). The consequences of incomplete dormancy release can cascade beyond germination, potentially affecting fitness in subsequent...

Sympatric European white oaks species display contrasting epigenetic response to soil water availability

Abstract In the context of climate change plants have to cope with adverse conditions, among which water scarcity is a major threat for their survival. They have developed diverse regulatory processes to face drought that may differ depending on their ecological niche. The two sy...

Rethinking common gardens for forest tree species in the face of climate change

Abstract Key message Maintaining forest resilience under climate change depends on understanding genetic adaptation and preserving diversity. Long-term common garden networks are essential for revealing how species and populations perform across life stages and environments. When...

Accurate MAG reconstruction from a complex soil microbiome through combined short- and HiFi long-reads metagenomics

Abstract Background Advances in high-fidelity long-read (HiFi-LR) sequencing technologies have opened new opportunities to explore the microbial genomic diversity of complex environments, such as soils. While short-read (SR) sequencing has enabled broad insights at the gene level...
