Cognitive impairment is one of the most functionally debilitating non-motor symptoms in Parkinson's disease (PD). Yet, current diagnostic and clinical practices rely heavily on subjective assessments and burdensome behavioral testing, which lack the temporal resolution to detect subtle deficits. While EEG and pupillometry offer promising non-invasive insights into cognitive processing, more scalable and objective methods are n...

Features of possible regional ionospheric memory manifested themselves at low-latitudes under solar eclipse conditions.

Background and aims The increasing use of non-conventional water resources in Mediterranean agriculture raises concerns regarding nutrient imbalances and the capacity of soils to buffer irrigation-driven chemical inputs. This study evaluated how the soil–plant system stabilizes plant nutritional status under irrigation with contrasting water chemistries. Methods Nutrient dynamics were assessed along the soil–water–plant contin...

Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...

Recent studies have highlighted the ecological importance of cryptic habitat space on coral reefs. These microhabitats, ranging from framework cavities to intra-branch space within marine macroalgae, can harbour diverse and ecologically relevant taxa. Here we show that brittle stars, ubiquitous across such cryptic habitats (reported densities exceeding 100 ind. m −2 ), represent an important, but previously neglected, source o...

This study evaluated concentrations of particulate matter with aerodynamic diameter ≤ 10 µm (PM10) and potentially toxic elements (PTEs) in three urban zones of Ilo, a coastal city in southern Peru, during the cold season (July–October 2022). The cold season is characterised by greater atmospheric stability and a lower mixing layer height, which favours pollutant accumulation and scenarios of higher potential exposure. Three c...

Background and Aims Climate change is posing a major threat to global agricultural productivity. Plant growth-promoting bacteria (PGPB) have emerged as sustainable tools to enhance crop tolerance to abiotic stress through different mechanisms. This study aimed to evaluate the physiological, biochemical, and transcriptomic responses of the Altoandina oat variety ( Avena sativa AV25T) under water deficit and to determine the eff...

The study of clines, or geographical variations of a given trait, can help understand how the interactions of genetics and local environments determine phenotypic diversity. The marine snail Littorina saxatilis (Olivi, 1792) exhibits a gradual change in the relative frequencies of shell color morphs across populations in the estuary system of the Rias Baixas (Galicia, NW Iberian Peninsula). A consistent pattern of distribution...

Burmeister's porpoises are cryptic and challenging to detect visually. More information on their acoustic signals could facilitate the use of passive acoustic monitoring (PAM) and help to better understand their ecology. Here, clicks were recorded from two different Burmeister's porpoise populations, one in Chile and the other in Peru, using a 4‐channel hydrophone array and a single‐channel hydrophone recorder. Burmeister's po...

In the Eastern South Pacific (ESP), blue whale ( Balaenoptera musculus subsp.) aggregations have been described for two feeding areas (in northern and southern Chile) and in the Eastern Tropical Pacific (ETP). However, despite the knowledge of these areas, little is known about the seasonal movements of blue whales between them. Comparisons of 1074 individual blue whales, photographed across these regions from 1992 to 2019, re...
