Cloud Forest Tree Growth Responses to Climate and Drought Vary by Island and Species in the Macaronesian Region

open access: yesJournal of Biogeography, Volume 52, Issue 4, April 2025.
ABSTRACT Aim Macaronesian cloud forests are insular ecosystems subjected to local environmental variability, but the responses of their tree species to climate variations have never been studied. Our aim was to assess how the variation in environmental conditions associated with the geographical location of several islands in three Macaronesian ...

Immunometabolic Effect of Nitric Oxide on Human Macrophages Challenged With the SARS‐CoV2‐Induced Cytokine Storm. A Fluxomic Approach

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 1, January 3, 2025.
Human macrophages activated by COVID‐19 cytokine storm do not express NOS2. Exogenous administration of NO improves macrophage function in pro‐inflammatory conditions. NO significantly alters the central metabolism of human macrophages, which may contribute to host defense.

Functional differences between herbs and woody species in a semiarid Mediterranean plant community: A whole‐plant perspective on growth, nutrient‐use and size

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 38-50, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Despite decades of research, a comprehensive understanding of trait coordination at the whole‐plant level remains elusive. Furthermore, while the link between above‐ground growth rates and leaf traits related to nutrient use is well established, much less is known about

Astrocytic Ca2+ activation by chemogenetics mitigates the effect of kainic acid‐induced excitotoxicity on the hippocampus

open access: yesGlia, Volume 72, Issue 12, Page 2217-2230, December 2024.
Main Points Astrocyte activation reversed brain glucose metabolism alterations after KA damage. Chronic astrocyte activation had neuroprotective effects and delimited the neuroinflammation. 18F‐FDG PET may allow tracking the impact of astrocytes in brain metabolism.

Antarctic Studies Show Lichens to be Excellent Biomonitors of Climate Change

open access: yesDiversity, 2019
Lichens have been used as biomonitors for multiple purposes. They are well-known as air pollution indicators around urban and industrial centers. More recently, several attempts have been made to use lichens as monitors of climate change especially in ...

Plant virus community structuring is shaped by habitat heterogeneity and traits for host plant resource utilisation

open access: yesNew Phytologist, Volume 244, Issue 4, Page 1585-1596, November 2024.
Summary Host plants provide resources critical to viruses and the spatial structuring of plant communities affects the niches available for colonisation and disease emergence. However, large gaps remain in the understanding of mechanisms that govern plant‐virus disease ecology across heterogeneous plant assemblages.

The impact of fungi on soil protist communities in European cereal croplands

open access: yesEnvironmental Microbiology, Volume 26, Issue 7, July 2024.
In cropping system soils, the interconnection between fungi and protists is stronger than typically recognized. This could hint at yet‐to‐be‐discovered trophic relationships. Abstract Protists, a crucial part of the soil food web, are increasingly acknowledged as significant influencers of nutrient cycling and plant performance in farmlands.
