The evolution and benefits of nest association and other reproductive strategies in North American minnows (Cyprinidae)
With over 293 species, Cyprinidae (minnows) is the largest family of fishes in North America. Although a diverse group of obvious ecological importance, very little is known about the life histories of North American minnows, including reproductive behavior. In order to promote understanding of the …

Investigating Reproductive Phenology and Alloparental Care in Leuciscid Fishes using Niche Theory Approaches
… reproductive mutualism of leuciscids known as nest association, a form of alloparental care characterized by an adult of one species guarding the offspring of another. I conducted this study with the leuciscid community of Toms Creek in which Bluehead Chub Nocomis leptocephalus is the primary …

Applying ecological models to positive interactions among lotic fishes: implications for population and community regulation at multiple spatial scales
… mutualistic reproductive interaction known as nest association, in which individuals of one species (nest associates) spawn in nests constructed by host species. In nest association, hosts provide unsilted gravel substrate for spawning nest associates, and increased parental care to associate …

Cheating and Selfishness in Reproductive Interactions among Nest Associative Cyprinids
… United States, one fish-fish mutualism is the nest association between Nocomis and other cyprinids. I assessed the role of host parental care while testing for the selfish-herd effect. Additionally, I examined multiple nest associates in order to elucidate potential cheaters. I utilized …

Distribution and Life History of Chrosomus sp. cf. saylori in the Upper Clinch River Watershed, Virginia
… and differing niche roles. I observed a nest association with Campostoma anomalum. Gonad weight was lower for C. sp. cf. saylori than closely-related congeners. Together, this information indicates that C. sp. cf. saylori are narrowly distributed and populations are small, fragmented, and …

Two Layers of Selfish-Herds in Spawning Aggregations of Chub (Nocomis Sp.) and its Nest Associates
… research suggests – specifically, by using nest associates to decrease its own risk of predation (creating a selfish-herd) and simultaneously forcing associate embryos into marginal nest locations while locating its own embryo in the safer locations within the nest (creating an "embryonic …

Effects of Temperature and Dissolved Oxygen on Development and Survival of Embryos in Nests of Bluehead Chub Nocomis leptocephalus
… embryos occur at high densities. The communal nesting system of the Bluehead Chub Nocomis leptocephalus and its nest associates provides an ecologically realistic setting in which these stressors may interact, as many species deposit eggs within gravel mounds where oxygen levels fluctuate and …
