Plants have been recognized to be capable of allocating more roots to rich patches in the soil. We tested the hypothesis that in addition to their sensitivity to absolute differences in nutrient availability, plants are also responsive to temporal changes in nutrient availability. Different roots of the same Pisum sativum plants were subjected to variable homogeneous and heterogeneous temporally - dynamic and static nutrient regimes. When given a choice, plants not only developed greater root biomasses in richer patches; they discriminately allocated more resources to roots that developed in patches with increasing nutrient levels, even when their other roots developed in richer patches. These results suggest that plants are able to perceive and respond to dynamic environmental changes. This ability might enable plants to increase their performance by responding to both current and anticipated resource availabilities in their immediate proximity.

Background: Changes in consumer food choices have been associated with transformation in the food environment. Despite the direct impact of consumers' food choices on their diet and health outcomes, there is a lack of comprehensive evidence regarding how various factors within the food environment impact these choices.
Methods: This study uses the Theory of Planned Behavior to examine how socio-psychological factors in the food environment influence consumers' healthy food choices.

Treatment wetlands (TW) are a popular choice for decentralized wastewater treatment, with substantial documentation on their capacity to manage conventionally monitored pollutants. However, most insights into their effectiveness against emerging contaminants come from lab and mesocosm studies with a limited number of compounds, highlighting knowledge gaps in their performance at full scale. This study provides a first long-term, full-scale assessment of TW ability to remove a large number of organic micropollutants (OMPs) and manage antibiotic resistance under real-world conditions.

Flumioxazin-based herbicides are frequently used in agriculture to control broadleaf weeds attributed to their high efficacy, rapid action, and residual soil activity, making these compounds a preferred choice over other herbicides in pre-emergence weed control. Due to their beneficial properties, use of these herbicides has significantly increased in recent years, raising concerns regarding potential environmental risks. This study aimed to examine the effects of a commercial flumioxazin-based formulation on different plant models.

Healthy plant-based diets, such as vegan and vegetarian diets, as well as planetary health diets, meet the recommendations of sustainable dietary patterns and are healthier for both the planet and humans. The adoption of these dietary patterns may depend on socio-demographic factors and individual motivations. This study aimed to analyse the association between socio-demographic factors and knowledge and attitudes towards vegan and vegetarian diets amongst university students.

Background: Water contamination is a global challenge, primarily due to heavy metal ions like lead (Pb), iron (Fe), cadmium (Cd), andmercury (Hg) as well as dyes. These pollutants enter the ecosystem from industrial waste and runoff, accumulate in the environment and pose a high risk to humans, animals and plants. Various sensors, such as colorimetric sensors, and electrochemical sensors have been developed to detect these ions and dyes.
