TAXON, Volume 74, Issue 5, Page 1106-1152, October 2025.Abstract Rubus ser. Glandulosi is one of the most taxonomically intricate taxa of the genus, which is by itself considered a taxonomical nightmare. Around 46 species are currently recognised in the group, but most of its morphological diversity could not be classified at the species level until recently due to unclear reproductive patterns, high ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract The Zagros orogen records the closure of the Neotethys Ocean by northward subduction of the oceanic slab beneath the Iranian plate. Northwestern Iran has undergone episodic volcanism since the Eocene, due to a shift of tectonic regimes from subduction to collision and post‐collisional extension, although the dynamics responsible for such ...

Archaeometry, Volume 67, Issue 5, Page 1267-1282, October 2025.Abstract We examine the number of sites with silver objects in China over a period of 3500 years to suggest that technologies that stimulated the indigenous exploitation of silver‐bearing ores were innovated during the Spring and Autumn period (c. 770–476 BCE), and that increased centralisation and bureaucratisation from the Warring States period (475 ...

Biodiversity in mountain soils above the treeline
Biological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

The stepwise rise of angiosperm‐dominated terrestrial ecosystems
Biological Reviews, Volume 100, Issue 5, Page 2131-2149, October 2025.ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

From Individual to Stand Performance in Hybrids: Challenging the Optimal Parental Genetic Distance
Evolutionary Applications, Volume 18, Issue 10, October 2025.ABSTRACT Hybridization, the interbreeding of distinct genotypes, drives evolutionary processes like speciation and adaptation, potentially via phenotypic transgression, where hybrids exhibit novel traits. In crop breeding, research has largely focused on optimizing heterosis to enhance hybrid performance, particularly for traits such as biomass.
