Tyrone Hayes. Tyrone B. Hayes (born July 29, 1967) is an American biologist and professor of integrative biology at the University of California, Berkeley. He is known for his research in frogs, concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes male frogs, causing them to display female characteristics.
Most notably, American conspiracy theorist Alex Jones cited research on the effects of atrazine on frogs, which can induce spontaneous sex change or hermaphroditism, claiming that the federal government of the United States was "putting chemicals in the water that turn the friggin’ frogs gay" as part of a "chemical warfare operation" or "gay ...
Atrazine has been a suspected teratogen, with some studies reporting causing demasculinization in male northern leopard frogs even at low concentrations. [50] A 2002 study by Tyrone Hayes , of the University of California, Berkeley, found that exposure caused male tadpoles to turn into hermaphrodites – frogs with both male and female sexual ...
Gay bomb. " Gay bomb " is an informal term referring to a hypothetical non-lethal psychochemical weapon about which the United States Air Force speculated. The unconventional idea involved the potential dispersion of sex pheromones among enemy forces, with the intent of generating mutual sexual attraction among them, causing mass confusion and ...
Why is there no mention to the 2010 Berkeley study, "Atrazine induces complete feminization and chemical castration in male African clawed frogs (Xenopus laevis)", published in Proceedings of the National Academy of Sciences with nearly 700 citations, which is the source of this conspiracy theory?
Male Dendropsophus microcephalus calling. Sexual selection in amphibians involves sexual selection processes in amphibians, including frogs, salamanders and newts.Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations ...
Frog hearing and communication. Frogs and toads produce a rich variety of sounds, calls, and songs during their courtship and mating rituals. The callers, usually males, make stereotyped sounds in order to advertise their location, their mating readiness and their willingness to defend their territory; listeners respond to the calls by return ...
