In such a scenario, southeastern blue suckers in the lower river may be a sink population dependent on reproduction upriver in Mississippi, similar to bluehead
and flannelmouth sucker populations above and below a salmonid barrier in the upper Colorado River system (Compton et al.

For example, the flannelmouth sucker (Catostomus latipinnis), bluehead
sucker (Catostomus discobolus), and white sucker (Catostomus commersonii) comprised 65-75% of the total catch in the upper Colorado River (Carter and others 1986).
Sexual selection and male characteristics in the bluehead
wrasse, Thalassoma bifasciatum; mating site acquisition, mating site defense, and female choice.
Status of the bluehead
shiner (Notropis hubbsi) in Illinois.
Wrasse Thalassoma bifasciatum and Bicolored Damselfish Stegastes partitus dominated the coral reefs of Honduras, Puerto Rico (Aguilar-Perera & Appeldoorn 2008) and Curacao (Nagelkerken et al.
Introduced into the frigid, bottle-green waters below Glen Canyon Dam for the pleasure of sport fishermen, trout have become a threat to fish native to the Colorado River--humpback chubs, flannelmouth suckers, and bluehead
suckers; they compete for food and prey on the young of these now rare or endangered species.
Small schools of juveniles or juveniles plus adults of yellowhead wrasse Halicoeres garnoti, bluehead
wrasse Thalassoma bifasciatum, clown wrasse H.
In contrast, the bluehead
wrasse (Thalassoma bifasciatum) lacks structure even at the scale of the entire Caribbean basin.
Other findings include new records and range extension for rarely collected species such as the mooneye (Hiodon tergisus), bluehead
shiner (Pteronotropis hubbsi), mud darter (Etheostoma asprigene), swamp darter (Etheostoma fusiforme), and the undescribed Ouachita darter (Percina sp.
The spatial spread of the most abundant species, bluehead
chubs, over a four-month period was characterized by upstream bias, diffusion-like spread, and persistent leptokurtosis.
