Extreme Drought Affects Visitation and Seed Set in a Plant Species in the Central Chilean Andes Heavily Dependent on Hummingbird Pollination

open access: yesPlants, 2020
Rising temperatures and increasing drought in Mediterranean-type climate areas are expected to affect plant–pollinator interactions, especially in plant species with specialised pollination.

Electronegativity under Confinement

open access: yesMolecules, 2021
The electronegativity concept was first formulated by Pauling in the first half of the 20th century to explain quantitatively the properties of chemical bonds between different types of atoms. Today, it is widely known that, in high-pressure regimes, the

Caracterización de la degradación de los pantanos de palmeras turbosos desde el espacio y sobre el terreno: Un estudio exploratorio en la Amazonia peruana

open access: yes, 2017
El Peru tiene la cuarta mayor area de turberas de los tropicos. Su cobertura terrestre de turba mas representativa es el pantano de palmeras (denominado a partir de ahora PP denso) dominado por la especie Mauritia flexuosa, que ha estado sometido a ...

Applying the Horizontal Visibility Graph Method to Study Irreversibility of Electromagnetic Turbulence in Non-Thermal Plasmas

open access: yesEntropy, 2021
One of the fundamental open questions in plasma physics is the role of non-thermal particles distributions in poorly collisional plasma environments, a system that is commonly found throughout the Universe, e.g., the solar wind and the Earth’s ...

Beyond species means – the intraspecific contribution to global wood density variation

open access: yesNew Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from
