Heidi S. Fisher, a doctoral candidate at Boston University said that they are trying to look at cues that might tell them what made these animals want to hybridize. Fisher's work, published in The Proceedings of the Royal Society B, strongly suggests the culprit is humic acid, a complex compound that results from degrading organic matter and is normally considered benign. Fisher tested whether female sheepsheads could choose between male sheepsheads and highlands in clean water, in water from the river and in clean water spiked with humic acid. Heidi S.
