Influence of personality traits on the response of a modelled population of stream-dwelling rainbow trout (Oncorhynchus mykiss) to microplastics consumption
No full textMicroplastics in freshwater habitats are consumed by fish, including stream-dwelling salmonids, which can alter food consumption or negatively affect swimming and foraging behaviour. As population-level effects are largely unknown, a population of stream-dwelling rainbow trout ( Oncorhynchus mykiss ) was simulated using the agent-based model ‘inSTREAM 7’ to model population-level effects (biomass) of behavioural changes caused by microplastics consumption. Individual fish were assigned all possible combinations of two personality traits (dominance, boldness/shyness) and consumed microplastics while foraging; and their microplastics consumption, body length and abundance were tracked for three different life stages (fry, juvenile, adult) for a period of 10 years. Three scenarios were explored: a low-impact scenario with microplastics causing decreased food consumption, a medium-impact scenario which added lower swimming speed and a high-impact scenario with additional reductions of foraging efficiency. Each scenario was tested for microplastics concentrations of 0%, 1% (i.e. current levels) and 3% (i.e. future levels) of drift food. Overall, microplastics consumption did not strongly affect trout abundance. Dominant adult trout consumed disproportionally more microplastics than all other fish, especially at higher microplastic concentrations. Personality traits influenced the response of the trout to microplastics ingestion: dominant and bold adults were smaller when food consumption was reduced; shy and subordinate adults were smaller when swimming speed was lowered; and all dominant adults, regardless of boldness, were smaller when foraging efficiency was impeded, with dominant and bold fry also less abundant in this scenario. However, effects on fish body length were only found at microplastic concentrations of 3%, indicating these outcomes can be prevented, as current levels of microplastics pollution are below this concentration. Nevertheless, microplastics ingestion may become an additional stressor that interacts with the myriad of mostly anthropogenic stressors that already affect wild salmonid populations.Mitac
Bioengineering of soils for ground improvement and stability: A review of nature-based technologies
No full textIn recent years, biologically inspired approaches have emerged as promising and sustainable alternatives to conventional soil improvement techniques. This review systematically examines research published between 2019 and 2024 on five major bioengineering strategies applied in geotechnical contexts: biopolymers, bioclogging, biocementation, revegetation with roots and fungi, and biochar amendment. The analysis evaluates their influence on geotechnical and hydraulic parameters such as unconfined compressive strength, shear resistance, permeability, and matric suction while also identifying technical limitations, environmental sensitivities, and implementation challenges. To ensure methodological traceability, a structured three stage review process was applied, supported by AI powered tools for literature discovery. Each technique is critically assessed in terms of laboratory validation, field scalability, and long term performance. In addition to individual evaluations, this study identifies growing trends in cross application and hybridization, including biochar, biopolymer blends and microbial enhancement of vegetative systems. These integrative solutions reflect a broader shift toward interdisciplinary, systems based engineering. Furthermore, emerging innovations such as enzyme induced calcite precipitation and AI assisted treatment optimization are discussed as drivers of future development. The review also highlights the absence of standardized design protocols and the limited availability of quantitative environmental and economic assessments across all techniques. By consolidating recent findings and mapping critical gaps, this review provides a comparative framework that supports the advancement of nature based soil technologies in slope stabilization, erosion control, and sustainable subsurface infrastructure

Fully Printed Flexible Polystyrene/Graphite-Based Temperature Sensor with Excellent Properties for Potential Smart Applications
No full textThis study presents an innovative temperature sensor based on a thermistor nanocomposite of graphite (Gt) and polystyrene (PS). The sensor exhibited notable thermal stability and film integrity, offering two distinct linear response regions within the tested temperature range of −10 to 60 °C. It demonstrated a sensitivity of 0.125% °C-1 between −10 and 10 °C, followed by another linear response with a sensitivity of 0.41% °C-1 from 20 to 60 °C. Furthermore, it exhibited a response/recovery time of 0.97/1.3 min at a heating/cooling rate of 60 °C min-1. The sensor maintained minimal baseline drift even when subjected to varying humidity levels. We assessed its mechanical flexibility and stability for hundreds of bending cycles at a bending angle of 30°, adapting to dynamic environmental conditions. The sensor’s thermomechanical test (response to mechanical stress under temperature fluctuations) underscored its adaptability over a temperature range of −10 to 60 °C. Notably, it displayed excellent chemical stability, maintaining consistent performance when subjected to harsh environmental conditions like exposure to corrosive gases and prolonged immersion in tap water. Real-world tests demonstrated its practical utility, including precise temperature measurements in solid objects and breath temperature monitoring. These findings suggest promising applications in healthcare, environmental monitoring, and various IoT applications
