University Students' Utility Value of Learning About a Local or Nonlocal Environmental Socioscientific Issue: Written Reflections and Instructional Contexts

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Socioscientific issues (SSIs) are central to science education, yet empirical research on learners' perceived relevance in SSI teaching and learning remains limited. Utility value is a relevance construct that refers to the perceived usefulness of learning for learners' lives.

Pre-emergence herbicides for weed control in walnuts

open access: yesCalifornia Agriculture, 1967
Walnuts are California's leading deciduous tree crop. Walnut orchardists spend over one million dollars annually for weed control on an estimated 140,000 acres. In addition, losses due to weeds in the orchards were recently estimated at $2,720,000 annually.

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Using programmable infusion pump in avian species – a validation methodology in geese

open access: yesWildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Economic Analysis of Infrastructure Investment and Break‐Even Carbon Prices for Low‐Water, Low‐Emission Farming Techniques in Vietnam

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Excessive water use in rice production is a major source of methane emissions, the dominant greenhouse gas from Vietnam's agricultural sector. Improving water‐use efficiency can enhance water security and reduce emissions, but achieving these gains requires substantial changes in farming practices and significant investment in supporting ...

Reflections on Adoption of New Agricultural Practices

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Research on adoption of new practices, technologies and systems in agriculture has generated thousands of publications over the past 70 years, covering uptake of agricultural practices spanning more than 100 years. This paper contains selected key lessons from the results of this enormous research effort, drawn from numerous reviews of the ...

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

open access: yesIntegrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

open access: yesJournal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.
