Context‐dependent relationships between genomic traits and plant performance in temperate grasslands

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2674-2689, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Genome size and ploidy level affect fundamental processes in plants—including growth rate, stress tolerance and dispersal ability—and may play a critical role in shaping species responses to changing environmental conditions. Central European temperate grasslands, which

On the functional form of the metallicity-giant planet correlation [PDF]

open access: yes, 2013
It is generally accepted that the presence of a giant planet is strongly dependent on the stellar metallicity. A stellar mass dependence has also been investigated, but this dependence does not seem as strong as the metallicity dependence.

Infection dynamics of endosymbionts that manipulate arthropod reproduction

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1787-1812, October 2025.
ABSTRACT A large proportion of arthropod species are infected with endosymbionts, some of which selfishly alter host reproduction. The currently known forms of parasitic reproductive manipulations are male‐killing, feminization, cytoplasmic incompatibility, parthenogenesis induction and distortion of sex allocation.

Triangle or tripod? Neither: A diagrammatic investigation into a sign’s visual representation

open access: yesSign Systems Studies
This paper takes a look at the morphological structure of the two dominant diagrams (the triangle and the tripod) used in semiotic literature to represent the irreducible triadic sign of C. S. Peirce in order to evaluate their diagrammatic aptitude, i.e.

Research Review: Help‐seeking intentions, behaviors, and barriers in college students – a systematic review and meta‐analysis

open access: yesJournal of Child Psychology and Psychiatry, Volume 66, Issue 10, Page 1593-1605, October 2025.
Background The prevalence of mental health problems among college students has increased over the past decade. Even when mental health services are available, many students still struggle to access these services. This systematic review and meta‐analysis aimed to identify the rates at which students actively seek or consider using formal help and to ...

Insect visitation patterns in diploid Centaurea aspera and its related allotetraploid and triploid hybrids: Similar rates but distinct assemblages

open access: yesAmerican Journal of Botany, Volume 112, Issue 9, September 2025.
Abstract Premise Polyploidy is key to plant evolution by contributing to speciation, diversification, and adaptability. However, the minority cytotype exclusion effect can limit the persistence of polyploids, which can be mitigated by reproductive barriers such as distinct insect visitation between cytotypes. In eastern Spain, the diploid C.
