Summary: Increasing levels of antibiotic resistance pose a major threat to public health. Understanding the costs and benefits of resistance can lead to better use of antibiotics and prevent the spread of resistance.

Summary: Plants have both physical and chemical defenses, but they are still attacked and damaged by insects with different feeding habits. Trade-offs between growth and defense traits play a crucial role in deterring herbivores, but a comprehensive understanding of the integrated defense system is still lacking.

Summary: Artificial light at night has adverse effects on the interactions between plants and pollinators, potentially altering their daytime interactions; Research shows that artificial light at night can change the interactions between plants and pollinators during the daytime, with the specific impact depending on the plant species.

Summary: This study reveals a nonhost resistance mechanism of plants against herbivores through genomic, transcriptomic, and metabolomic analysis. The results show that a module triggered by Empoasca leafhoppers induces the synthesis of a specific compound in crop plants, which confers resistance to leafhoppers.

Summary: Multiresistance plasmids have evolutionary advantage in antibiotic treatment environments and impose fitness costs on bacteria. This study investigates the contribution of plasmid-borne resistance genes to bacterial fitness and finds that particular resistance genes are responsible for the cost of the plasmid.

Summary: Multiresistance plasmids provide bacterial cells with protection against multiple antibiotics, but can also reduce the fitness of bacterial cells. Some resistance genes carried by plasmids incur costs on bacterial cells, while others are cost-free.

Summary: This study investigates the fitness cost associated with insect resistance to the insecticide chlorantraniliprole in Spodoptera frugiperda. The research shows that there is no fitness cost when the pest feeds on corn plants, but a significant fitness cost is observed on soybean and cotton plants.

Summary: In the context of climate change, developing countries are exploring the repurposing of coal plants for productive uses. This study develops a cost-benefit framework and applies it to a representative coal plant in India, finding a strong economic rationale for repurposing. The research also provides a methodology for selecting plants for repurposing.

Summary: Aboveground plant-to-plant communication can reduce root nodule symbiosis and soil nutrient concentrations by inducing chemical defenses in plants, affecting both aboveground and belowground ecosystems.

Summary: The influence of diurnal or circadian time on the accumulation of plant specialized metabolites in response to stress remains largely unknown. This study investigated the contribution of time of day to the induced defenses of Brassica crops under mechanical wounding stress. The results showed that the accumulation of glucosinolates (GSLs) differed depending on the time of day of wounding. Furthermore, the activation of phytochemicals in response to wounding primed the plants against herbivore attack. The findings highlight the significant role of time of day in the wound stress responsive metabolome and its impact on plant-herbivore interactions.

Summary: There is a trade-off between plant resistance and tolerance. The study found a negative relationship between mechanical defenses and tolerance, while there was no significant association between chemical defenses and tolerance. Plant adaptation to light environments may affect the trade-off between resistance and tolerance.

Summary: This paper discusses the trade-off between cognitive costs and values in an individual's decision-making process, and analyzes the fundamental properties required for the decision to stop thinking to be represented by a cost-benefit analysis. Additional properties are then provided to add structure to the value of reasoning function. The paper demonstrates how the model applies to various contexts and sheds light on patterns of behavior where the cost-benefit approach does not seem to hold.

Summary: Despite the lack of studies on the benefits and costs of pollinator conservation, a survey was conducted among three US universities to assess the benefits of becoming Bee Campus USA certified. The study also examined the impact of reminders on student sustainability fees on willingness to pay. The results showed that the net benefits for each university were mostly positive, with information reminders having little effect on support for pollinator conservation.

Summary: Hydropower construction can result in both biodiversity loss and creation of livelihood opportunities. This study evaluates the economic impact of the Nam Che 1 Hydropower Project in Laos, using a cost-benefit analysis that considers both environmental and economic ripple effects. The findings demonstrate that, when taking into account the spillover effects, the project is beneficial. Policymakers should consider the potential environmental impacts and economic spillovers when evaluating such projects.
