“…Pastures can also provide a sink for soil organic C, which can foster the recoupling of nutrient cycling (Lemaire et al., 2014; Reeves et al., 2014; Soussana & Lemaire, 2014). Prairie‐strip planting along wildlife corridors, slope contours within agricultural fields, and in waterways can be effective at removing resource‐ and income‐draining areas of a field from production, controlling erosion, filtering nutrients and chemicals from runoff, and strengthening biodiversity and habitat for wildlife (Alt et al., 2023; Kemmerling et al., 2022; Schulte et al., 2017).…”

Contemporary agricultural systems can be generalized as highly specialized operations that are fueled by mechanization, supplied with external nutrients to maximize production, crops protected by petrochemicals to fight against weed, disease, and insect pressures, and livestock protected by therapeutics to ward off virus and bacterial infections when managed in confinement. Such specialized systems have led to low levels of diversity, elevated environmental risks from contamination, loss of soil organic matter, ecological instability, and limited adaptability to climate change. More diversified farming systems are possible, but research required to characterize them in a holistic manner as an alternative to contemporary, specialized systems remains challenging to fund and sustain over time, primarily because they require more labor, management skills, and accessible markets to achieve additional ecological, environmental, and social goals. We share some perspectives as to (1) how specialized systems became the norm and (2) what changes could be made to reverse some ecological risks and environmental declines associated with specialization, acknowledging there is no panacea. Strong evidence exists for perennial forages to restore soil organic C and N, but system‐level analyses of the net balance in greenhouse gas emissions remain to be characterized in the myriad of potential integrated crop‐livestock systems that might be deployed across the diversity of edaphic, environmental, and socio‐economic conditions. We suggest there are abundant opportunities for more sustainable agricultural production to sequester soil organic C, reduce greenhouse gas emissions, and develop more climate‐resilient agricultural systems that will be needed in a future dominated by climate change issues.This article is protected by copyright.

“…Worldwide, AMR is reported to be responsible for 700,000 deaths each year ( Wang et al, 2019 ). As a result, AMR has attracted great attention, particularly regarding its formation mechanisms ( Cho et al, 2018 ; Cepas et al, 2019 ; Shahin et al, 2019 ; Kaszab et al, 2023 ) and removal processes ( Saha and Mukherjee, 2019 ; Alt et al, 2023 ). AMR include intrinsic ( Roberts et al, 2021 ) and acquired resistance ( Shahin et al, 2019 ).…”

IntroductionBacterial resistance presents a major challenge to both the ecological environment and human well-being, with persistence playing a key role. Multiple studies were recently undertaken to examine the factors influencing the formation of persisters and the underlying process, with a primary focus on Gram-negative bacteria and Staphylococcus aureus (Gram-positive bacteria). Enterococcus faecalis (E. faecalis) is capable of causing a variety of infectious diseases, but there have been few studies of E. faecalis persisters. Previous studies have shown that the sex pheromone cCF10 secreted by E. faecalis induces conjugative plasmid transfer. However, whether the pheromone cCF10 regulates the persistence of E. faecalis has not been investigated.MethodsAs a result, we investigated the effect and potential molecular mechanism of pheromone cCF10 in regulating the formation of persisters in E. faecalis OG1RF using a persistent bacteria model.Results and discussionThe metabolically active E. faecalis OG1RF reached a persistence state and temporarily tolerated lethal antibiotic concentrations after 8 h of levofloxacin hydrochloride (20 mg/mL) exposure, exhibiting a persistence rate of 0.109 %. During the growth of E. faecalis OG1RF, biofilm formation was a critical factor contributing to antibiotic persistence, whereas 10 ng/mL cCF10 blocked persister cell formation. Notably, cCF10 mediated the antibiotic persistence of E. faecalis OG1RF via regulating metabolic activity rather than suppressing biofilm formation. The addition of cCF10 stimulated the Opp system and entered bacterial cells, inhibiting (p)ppGpp accumulation, thus maintaining the metabolically active state of bacteria and reducing persister cell generation. These findings offer valuable insights into the formation, as well as the control mechanism of E. faecalis persisters.

“…The use of native prairie plant species in vegetative filter strips associated with manure management on confined animal feedlot operations has not yet been assessed, however. Prairie strips decrease sediment movement and nutrient loss from runoff, and can also reduce the transport of manure-associated contaminants off agricultural fields (Alt et al 2023, Craig et al 2022, commonly a major concern with manure usage. Manure could also potentially be applied to prairie integrated within cropland to assist with disposal.…”

“…While improved manure collection, storage, and transportation technologies are being developed, incorporating vegetative buffer strips into the agricultural landscapes could provide an opportunity for waste disposal with a natural filter to decrease nutrient runoff. These vegetative buffers could be made up of native perennial plants thus providing wildlife habitat while addressing water quality concerns by trapping and absorbing excess nutrients and pollutants (Soil and Water Conservation Society, n.d.) and decreasing antimicrobial resistance risks associated with manure use (Alt et al 2023, Flater et al 2022.…”
