Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Seed dispersal of Japanese stone pine by the Eurasian Nutcracker

open access: yesORNITHOLOGICAL SCIENCE, 2003
Seed dispersal of Japanese stone pine Pinus pumila by the Eurasian Nutcracker Nucifraga caryocatactes was studied at Mt. Apoi in Hokkaido, northern Japan. The seed foraging and caching behavior of diurnal birds and mammals was observed, and the relative importance of each species for pine seed dispersal was examined.

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Morphological variability of cones and seeds of aleppo pine and stone pine in Tunisia

open access: yes, 2004
Une étude sur la variabilité morphologique des cônes et des graines de Pinus halepensis Mill. et Pinus pinea L. en fonction des conditions géographiques des stations a été entreprise. L'analyse de la variance des paramètres morphologiques étudiés, pour les deux espèces, montre des différences inter-stations hautement significatives.

Synthetic Imagery Improves Ecological Classification When Real Data Are Scarce, Not Direct Substitutes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Image generation models can create synthetic ecological datasets and potentially alleviate limitations from sparse real data. Using 20 tree genera across community‐science and street‐view imagery, we tested whether synthetic images could replace or supplement real data for image classification.

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...

RETRACE Project: How to Enhance Resilience to Climate Risks in Pacific and Arctic Indigenous Communities?

open access: yesSustainable Development, EarlyView.
ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

The Couch: Belonging, Memory, and the Making of the Self—A Heartfelt Autoethnography

open access: yesSymbolic Interaction, EarlyView.
This heartfelt retrospective autoethnography explores a personal episode of adolescence through the lens of ritual, memory, and symbolic interaction. At the age of 14, after returning to Italy following years abroad, I found myself on the margins of a gang of boys whose shared language, stories, and music represented the codes of belonging I yearned to
