Differential nutrient limitation and tree height control leaf physiology, supporting niche partitioning in tropical dipterocarp forests

open access: yesFunctional Ecology, Volume 36, Issue 8, Page 2084-2103, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Revealing the mechanisms of environmental niche partitioning within lowland tropical forests is important for understanding the drivers of current species distributions and potential vulnerability to environmental change.

Nocturnal dissolved organic matter release by turf algae and its role in the microbialization of reefs

open access: yesFunctional Ecology, Volume 36, Issue 8, Page 2104-2118, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The increased release of dissolved organic matter (DOM) by algae has been associated with the fast but inefficient growth of opportunistic microbial pathogens and the ongoing degradation of coral reefs.

The fate and transit time of carbon in a tropical forest

open access: yesJournal of Ecology, Volume 109, Issue 8, Page 2845-2855, August 2021., 2021
The transit time distribution quantifies the time it takes for photosynthates to appear in the respiration flux. For a tropical forest in Colombia, it predicts that 50% of fixed carbon is respired in <0.5 years, and 95% in <69 years. Editor's Choice Abstract Tropical forests fix large quantities of carbon from the atmosphere every year; however, the ...

Intraoperative imaging for remnant viability assessment in bilateral posterior retroperitoneoscopic partial adrenalectomy in an experimental model

open access: yesBJS (British Journal of Surgery), Volume 107, Issue 13, Page 1780-1790, December 2020., 2020
Currently, the minimal functional adrenal remnant size, and the impact of intraoperative imaging technologies on remnant function after partial adrenalectomy, is unknown. In the present experimental study, intraoperative perfusion assessment, using quantitative fluorescence imaging, confocal laser endomicroscopy and contrast‐enhanced CT, enabled ...

Chemical signature of colorectal cancer: case–control study for profiling the breath print

open access: yesBJS Open, Volume 4, Issue 6, Page 1189-1199, December 2020., 2020
Available screening methods for colorectal cancer have poor reliability and low patient compliance. Cancer cells produce altered metabolites, which are transported in the bloodstream and released in the alveoli; these volatile organic compounds (VOCs) can be detected in exhaled breath.

Sleep Deprivation and Oxidative Stress in Animal Models: A Systematic Review

open access: yesOxidative Medicine and Cellular Longevity, Volume 2015, Issue 1, 2015., 2015
Because the function and mechanisms of sleep are partially clear, here we applied a meta‐analysis to address the issue whether sleep function includes antioxidative properties in mice and rats. Given the expansion of the knowledge in the sleep field, it is indeed ambitious to describe all mammals, or other animals, in which sleep shows an antioxidant ...

Strong scale‐dependent relationships between fine‐root function and soil properties uncovered with spatially coupled sampling

open access: yesNew Phytologist, Volume 246, Issue 6, Page 2506-2521, June 2025.
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Vegetative stage and soil horizon respectively determine direction and magnitude of rhizosphere priming effects in contrasting tree line soils

open access: yesFunctional Ecology, Volume 38, Issue 9, Page 1984-2002, September 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tree lines in high latitudes and high altitudes are considered sentinels of global change. This manifests in accelerated encroachment of trees and shrubs and enhanced plant productivity, with currently unknown implications for the carbon balance of these biomes.

Reframing wildlife disease management problems with decision analysis

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Contemporary wildlife disease management is complex because managers need to respond to a wide range of stakeholders, multiple uncertainties, and difficult trade‐offs that characterize the interconnected challenges of today. Despite general acknowledgment of these complexities, managing wildlife disease tends to be framed as a scientific ...

El marco de razonamiento clínico de Bobath: Un modelo de ciencia de sistemas para abordar la complejidad de los trastornos del neurodesarrollo incluida la parálisis cerebral

open access: yesDevelopmental Medicine &Child Neurology, Volume 66, Issue 8, Page e120-e129, August 2024.
Resumen La actual práctica de desarrollo Bobath recomendada dentro del Marco de Razonamiento Clínico Bobath (BCRF) puede conceptualizarse utilizando la visión de la ciencia de los sistemas. Proporciona, así, una perspectiva holística de la interrelación e interconexión de las variables asociadas con la discapacidad aparecida durante la infancia.
