Conservation implications of herbicides on seagrasses: sublethal glyphosate exposure decreases fitness in the endangered .

Worldwide seagrass populations are in decline, calling for urgent measures in their conservation. Glyphosate is the most widely used herbicide globally, leading to increasing concern about its ecological impact, yet little is known about the prevalence or impact of glyphosate on seagrasses. In this study, we investigated the effect of sublethal glyphosate exposure on the endangered seagrass, , to identify effects on growth, photosynthetic pigments and leaf morphology as measures of seagrass fitness.
