Just got a notice in an environmental trade rag that referenced this same study. Read it closely, it states that it's not really the glyphosate that is toxic to amphibians (and only some) but the surfactant (POEA) that causes the harm.
It specifically eradicated grass (leopard) frog tadpoles. That really sucks, as they are a prime catfish bait...not to mention the simple loss of biodiversity. Seems grass frogs are having a hard time all over...could this be the reason?
