Pre-fire forest type as an integrated indicator of long-term post-fire aboveground biomass recovery in boreal forests

As the largest terrestrial biome, boreal forests play a critical role in the global carbon cycle, support diverse wildlife habitats, and sustain timber production, while wildfires represent a major natural disturbance shaping their function. Understanding post-fire aboveground bi...

A Material-Relational Ontology of Data: Addressing Ethical Challenges in Psychological Research in a Data-Driven Era

The shift to a society organized around digital data has come with significant—although sometimes still underappreciated—implications for psychological research. In part, this is owed to the narrowness of discussions about data ethics in the discipline, although also to the ontol...

The context of sport as theoretical leverage: advancing institutional theory through race and organizational behavior analyses

Purpose This paper argues that sport offers a rich and underutilized context for advancing institutional analyses of race and organizational behavior. Sport, as an empirical context, is highly visible, emotionally charged and a socially embedded institution where internal and ext...

Governing through numbers: a theoretical framework for understanding how accounting information influences megaproject governance

Purpose This paper aims to explore how accounting information shapes the governance of megaprojects by integrating insights from institutional theory and governmentality perspectives into a unified theoretical framework. Design/methodology/approach The framework highlights the in...

A dynamic, physics-driven life cycle model for citrus supply chain: Evidence from a South Africa–Netherlands maritime trade route

Agri-food chains, especially fruit, produce about 10% of global GHG emissions, with more than half arising after harvest. Yet current methods, such as life cycle assessment (LCA), lack the spatial, temporal and physiological detail needed to resolve stage-specific drivers of envi...

Placentitis and abortion caused by canine distemper virus in a Linnaeus’s two-toed sloth

Canine distemper virus (CDV; family Paramyxoviridae , taxon species Morbillivirus canis ) causes systemic disease in a broad range of mammalian hosts. CDV commonly targets epithelial, lymphoid, and nervous tissues. Reproductive disease is reported less frequently. Here, we descri...

Feeding regime alters mitochondrial metabolism in beef skeletal muscle

Abstract Plane of nutrition influences animal growth rate and muscle fiber composition, potentially through altering skeletal muscle metabolism. The objective of this study was to evaluate changes in skeletal muscle metabolism in response to altering diet without changes in growt...

Mechanistic Basis of Nanobubble Functionality in Food Systems: Linking Electrokinetic Stabilization, Transport Dynamics, and Functional Outcomes

ABSTRACT Recently, there has been a surge in shifting of scientific interest towards the adoption of nonthermal technologies in food processing applications. Nanobubble (NB) technology is one of the emerging green technologies that has gained increased attention over recent years...

Clinical Behaviour and Outcome of Pelvic Osteosarcoma in Dogs: A Retrospective Multicentre Analysis of 74 Cases (2007–2025)

Although osteosarcoma is the most common primary bone tumour in dogs, involvement of the pelvic bones is rare. The aim of the present study was to describe clinical presentation, identify possible prognostic factors, and evaluate outcomes in dogs diagnosed with pelvic osteosarcom...

Structural insights into the polytopic Escherichia coli phosphoglycosyl transferase WbaP

Abstract Host–pathogen interactions frequently depend on key components of the bacterial cell surface, such as capsules and lipopolysaccharides in Gram-negative bacteria. The first step in the synthesis of lipid-linked polysaccharides is the substitution of a uridine diphosphate...

Fatigue-induced decline and recovery of maximal motor unit firing rates did not differ between males and females in two muscles of the quadriceps femoris

Studies on sex-related differences in motor unit (MU) behaviour with muscle fatiguing tasks are limited, particularly during contractions of maximal intensity and usually to one muscle within a synergistic group. Therefore, the purpose was to investigate the influence of sex and...

Biocontrol of tomato soilborne diseases by fungivorous nematode Aphelenchoides bicaudatus

<title>Abstract</title> Crop soil-borne diseases caused by pathogens, such as Fusarium spp. and root-knot nematodes, contribute to substantial yield losses worldwide. This study investigated the biocontrol potential of the fungivorous nematode, Aphelenchoides bicaudatus isolate A...

When the advisor is an algorithm: governing agri-food knowledge in the age of AI and misinformation

CONTEXT Artificial intelligence is becoming an important interface through which farmers, advisors and policymakers access agricultural knowledge, while misinformation increasingly circulates through the same digital channels. OBJECTIVE This Perspective develops the concept of ag...

Resolving Hidden Stoichiometriesin Bacterial ProteasomeActivator (Bpa)-Substrate Complexes by Cryo-EM and Charge DetectionMass Spectrometry

Abstract Bacterial proteasome activator (Bpa) is a regulatory particle within the Mycobacterium tuberculosis (Mtb) proteasome system that facilitates ATP-independent substrate engagement and delivery to the 20S core particle (CP) for degradation. The best characterized Bpa substr...

Numerical Investigation of a Compact Air-Cooled EV Battery Thermal Management System Using Circumferential Fins

Battery thermal management systems (BTMSs) are essential for maintaining the performance, efficiency, durability, and safety of electric-vehicle battery packs. Although fin-enhanced air-cooled BTMSs offer a simple and leakage-free cooling solution, their practical implementation...

Newcastle disease virus is a safe and immunogenic respiratory-delivered vaccine against SARS-CoV-2 in a ferret model

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has caused close to 800 million infections and over 7 million deaths worldwide. In addition to its impact on human health, the virus has shown cross-species transmission, including spillover into mustelids such as m...

Early pre-symptomatic and sex-specific cardiac remodeling precedes heart failure in zebrafish with human actin mutation

Dilated cardiomyopathy (DCM) is a leading cause of heart failure with notable sex differences in susceptibility and progression. Although sarcomere mutations such as cardiac actin ACTC1 p.T126I contribute to familial DCM, the in vivo effects and sex-specific consequences remain u...

Incidence and attributes of chimeric COI and 18S rDNA sequences derived from nematode-infected arthropods

Abstract Background PCR amplification of mixed-template samples can generate chimeric sequences, molecules that combine partial sequences from two or more source organisms. These artefacts pose a significant challenge for high-throughput sequencing studies, generating both type I...

Bacillus velezensis B313-6 as a Potential Biocontrol Strain Against Anthracnose of Panax quinquefolius, and Its Fermentation Optimization, and Field Efficacy on American Ginseng

Anthracnose of American ginseng is caused by Colletotrichum panacicola. In this study, Bacillus velezensis B313-6, isolated from the rhizosphere soil of American ginseng, was identified based on morphological, physiological, biochemical, 16S rRNA, and the gyrase subunit A protein...

Seasonal variation of liver and muscle mercury across two populations of a freshwater sport fish

Abstract Objective North-temperate fishes fluctuate in their energy status, metabolic rate, and behavior in response to seasonal changes in temperature and light, which could influence tissue concentrations of biomagnifying contaminants like mercury (Hg). Yet, repeated sampling w...
