Ovarian growth impairment after chronic exposure to Roundup Ultramax® in the estuarine crab Neohelice granulata
Adult females of the estuarine crab Neohelice granulata were exposed to the glyphosate formulation Roundup Ultramax® during the entire 3-month pre-reproductive period. At the end of the assay, a significant higher increment of glycemia was noted at both glyphosate concentrations assayed (0.01 and 0....
