Bats of a remote island: integrated genetic and bioacoustics monitoring confirms species occurrence in Flores (Azores, Portugal)

Abstract. Island ecosystems often harbour unique and vulnerable species, yet many remain poorly documented. In the Azores archipelago, two extant bat species are known to occur: the endemic Nyctalus azoreum and the Macaronesian endemic Pipistrellus maderensis. On Flores Island, p...

A global dataset of forest disturbance regimes derived from satellite biomass observations

Abstract. Forests play a central role in the global carbon cycle by serving as critical carbon sinks for atmospheric CO2. Yet, the stability and continued capacity of these sinks are increasingly threatened by a growing number of disturbances. Accurately representing the stochast...

From Transparency to Transport: Optoelectronic and Interfacial Signatures of n-Type ITO, FTO, ZnO and TiO2 Semiconductors

Transparent conducting oxides and electron transport layers are central to optoelectronic devices, yet their interfacial electronic behavior remains strongly dependent on substrate chemistry, defect states, and surface potential alignment. Here, we compare ITO and FTO transparent...

‘Poetry is not an art object but a useful object’: Mário Pinto de Andrade, Literary Activism and International Solidarity in Angola’s Liberation Struggle

This article investigates the role of poetry and literary publications as tools for building international solidarity during the early phases of the Angolan liberation struggle. It identifies Mário Pinto de Andrade – founding member and first president of the Movimento Popular de...

A New Hardware/Software Assistive Wi-Fi Device for Elderly Bed-Exit Event at Night

This article describes a new hardware/software alert system designed to assist elderly people and prevent falls due to bed-exit events at night. To assist the elderly during the night, it is important to implement automatic lighting activation in the bedroom. This helps reduce th...

Maternal BMI modulates cord plasma NT-proBNP in gestational diabetes linking cardiac stress to insulin-cortisol crosstalk

Abstract Gestational diabetes mellitus (GDM) is an increasingly prevalent pregnancy disorder associated with adverse maternal and neonatal outcomes, including an increased risk of early-onset cardiovascular disease in infants. GDM is associated with cardiac structural and functio...

Bivalve Gut Microbiome Responses to Sediment Characteristics and Anthropogenic Activities in Cerastoderma edule (Linnaeus, 1758)

Abstract Estuaries are dynamic ecosystems influenced by fluctuating environmental conditions and sediment-associated contamination, which may affect host-associated microbiomes. This study investigated the gut microbiome of the bivalve Cerastoderma edule across three estuarine si...

Impact on health outcomes of treating all eligible large B-cell lymphoma patients with axicabtagene ciloleucel in Portugal – A modeling approach

AIM: This study aimed to quantify the health benefits that can be achieved by treating axicabtagene-ciloleucel (axi-cel)-eligible large B-cell lymphoma patients with axi-cel instead of historical standard of care (hSoC) in Portugal. "Estimated Opportunity Lost" quantified the dif...

Long-Lived Interfacial Charge Separation in PyrenylimidazolylPhthalocyanine@Transition Metal Dichalchogenide Heterostructures

Abstract Pyrenylimidazolyl-functionalized free-base phthalocyanines (H2Pc) and their zinc complexes (ZnPc) constitute multifunctional building blocks for realizing heterostructures with liquid phase exfoliated transition-metal dichalcogenides (LPE-TMDs). Here, we report the synth...

A Reproducible Workflow for AIS-Based ETA Forecasting: Evaluating the Influence of Data Preprocessing and Machine Learning Model Selection

Accurate Estimated Time of Arrival (ETA) forecasting is essential for improving operational planning and decision-making in modern ports. While machine learning has significantly enhanced ETA prediction using Automatic Identification System data, the impact of data preprocessing...

Modernizing the TRIAD ecological risk assessment framework. Part II: Omic methods for high-resolution biological risk indicators

<ns5:p>The TRIAD framework is a widely used approach to assess site-specific ecological risk by integrating three Lines of Evidence (LoE): chemical, ecotoxicological, and ecological. As environmental contamination grows increasingly complex, the framework requires modernization i...

Waste Literacy Among Portuguese First-Year Tertiary Students After Compulsory Environmental Education

Waste management is essential for addressing local and global environmental challenges. Failure to manage waste effectively results in several consequences, including environmental degradation, public health risks, and economic costs. Besides the need for adequate and up-to-date...

Esteya spp. reduce Bursaphelenchus xylophilus reproduction in Pinus pinaster seedlings without consistent improvements in disease outcomes

Abstract BACKGROUND Pine wilt disease, caused by Bursaphelenchus xylophilus , threatens pine forests worldwide, yet sustainable biological control strategies remain limited. We evaluated the effects of pre‐emptive inoculation with Esteya vermicola and E. floridanum on nematode re...

An in-depth comparison: first wave of mpox in Rio de Janeiro, Brazil and Lisbon, Portugal

Abstract Background The 2022 mpox outbreak spread rapidly beyond endemic regions, affecting multiple countries with broadly similar transmission patterns but different public health responses and surveillance systems. We compared laboratory-confirmed mpox infections reported duri...

Revealing spatial patterns and depth-dependent controls of soil organic carbon density across China using interpretable machine learning

Abstract Soil organic carbon density (SOCD) is a key indicator of soil health and a critical component of terrestrial carbon storage, yet its large-scale spatial organization and environmental controls remain insufficiently understood. Here, we assessed national-scale patterns an...
