Variation of seedling recruitment in wet meadow species over 6 years: Positive effects of mowing and negative effects of fertilization

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1693-1704, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Germination and seedling recruitment are stages of the plant life cycle, which are highly sensitive to biotic and abiotic filtering. Simultaneously, seedling regeneration is considered crucial for biodiversity maintenance in grasslands and is strongly affected by ...

Corroborating the equivalence between the Duffin-Kemmer-Petiau and the Klein-Gordon and Proca equations

open access: yes, 2014
It is shown that the Hamiltonian version of the Duffin-Kemmer-Petiau theory with electromagnetic coupling brings about a source term at the current. It is also shown that such a source term disappears from the scenario if one uses the correct physical ...

Grain under pressure: Harnessing biochemical pathways to beat drought and heat in wheat

open access: yesThe Plant Journal, Volume 122, Issue 6, June 2025.
SUMMARY Erratic climate patterns represent a remarkable challenge to global food security, particularly affecting staple cereal crops of which wheat (Triticum aestivum) plays a critical role in annual agricultural production globally. It has been shown that over the last four decades, wheat cultivation has faced an escalating vulnerability to a variety

Delta-semidefinite and delta-convex quadratic forms in Banach spaces

open access: yes, 2007
A continuous quadratic form ("quadratic form", in short) on a Banach space $X$ is: (a) delta-semidefinite (i.e., representable as a difference of two nonnegative quadratic forms) if and only if the corresponding symmetric linear operator $T\colon X\to X^*
