| the first record of fish as paratenic hosts of falcaustra spp. (nematoda: kathlaniidae). | two types of third-stage nematode larvae (most of which were encapsulated) were collected from the abdominal cavity and liver of the freshwater fishes etheostoma fonticola, etheostoma lepidotum, cichlasoma cyanoguttatum, lepomis auritus, lepomis sp., and gambusia affinis in texas and are referred to the genus falcaustra. this is the first record of falcaustra larvae from fishes, and their presence may reflect the importance of fishes as paratenic hosts of turtle parasites in this genus. | 1995 | 7472886 |
| assessment of mosquitofish (gambusia affinis) health indicators in relation to domestic wastewater discharges in suburbs of houston, usa. | personal care products, pharmaceuticals, and other contaminants of emerging concern (cecs) in domestic wastewater treatment plant (wwtp) effluents can impact aquatic organisms. health indicators were compared for mosquitofish (gambusia affinis) collected above and below wwtp discharges from five streams in suburban areas of the houston metropolitan area, texas, usa. specimens were evaluated for reproductive, morphological, and histological indicators. several indicators revealed significant spat ... | 2014 | 24615506 |
| male genital size reflects a tradeoff between attracting mates and avoiding predators in two live-bearing fish species. | male genitalia may experience more rapid, divergent evolution than any other animal character, but why? research during the past several decades has culminated in the view that genital diversification primarily results from postmating sexual selection (e.g., sperm competition or cryptic female choice). however, the potential roles of premating sexual selection (e.g., mate choice) and natural selection have received little attention. we examined the possible importance of these mechanisms by inve ... | 2005 | 15894618 |
| spatial and temporal distribution of the asian fish tapeworm bothriocephalus acheilognathi (cestoda: bothriocephalidea) in the rio grande (río bravo del norte). | recent collections of the asian fish tapeworm bothriocephalus acheilognathi in the rio grande have raised concern about the potential impacts on rio grande endemic and imperiled fishes. the objectives of this study were to determine distribution and definitive hosts of the asian fish tapeworm within the rio grande drainage and to quantify occurrences and abundances. in total, 1,992 fish spanning 11 families were collected and examined for asian fish tapeworms in the rio grande and the pecos and ... | 2010 | 21192548 |
