Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs

open access: yesEcography, EarlyView.
Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.

Chronic sleep deprivation promotes drug‐resistant epilepsy via the BMAL1‐mTOR‐P‐gp axis

open access: yesEpilepsia Open, EarlyView.
Abstract Objective The interplay between chronic sleep deprivation and drug‐resistant epilepsy (DRE) has gained increasing attention. Brain and muscle Arnt‐like protein 1 (BMAL1), which is implicated in sleep disturbance, has an unclear role in DRE. We aimed to investigate the role of BMAL1 in sleep deprivation‐induced DRE. Methods A pentylenetetrazole

Optimized Parameter Extraction in Triple Diode Solar PV Models Using Kookaburra‐based Dwarf Mongoose Approach

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Improving photovoltaics (PV) system performance through simulation requires accurate PV models. The nonlinear relationship between current and voltage, coupled with incomplete manufacturer data, presents a significant challenge in parameter estimation.

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

The prevalence of Streptococcus equi subsp. equi carriers in the Netherlands

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Streptococcus equi subspecies equi (S. equi) carriers are thought to be important drivers for strangles outbreaks. Limited data are available on the prevalence of carriers in European horse husbandry settings. Objectives To estimate the prevalence of S.

Subsistence harvest for food and pets associated with declining global mammal populations

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Subsistence harvest can have substantial impacts on mammalian biodiversity, yet its effects on the conservation status of mammal species are poorly understood. We analyzed trade and use data in species accounts from the International Union for Conservation of Nature (IUCN) Red List to examine the effects of subsistence harvest on the conservation ...
