We determined seasonal foraging modes of four sympatric darter species, Etheostoma lynceum, E. stigmaeum, E. swaini and Percina nigrofasciata, from Beaverdam Creek, Mississippi (USA) at two scales of taxonomic resolution: (1) chironomid prey identified to family and (2) chironomid prey identified to genus/species. When chironomids were identified to family, high proportional similarity (PS) and low niche breadth (NB) values suggested the darters fed opportunistically on a relatively small… Expand

Figures and Tables from this paper

The ecological morphology of darter fishes (Percidae: Etheostomatinae)
TLDR
It is found that darters exhibit relatively low variation in trophic morphology when compared with two other radiations of teleost fishes, and that the observed variation is related more to differences in microhabitat use than to Differences in prey type. Expand
Selective predation by reintroduced juvenile Lake sturgeon (Acipenser fulvescens) in Ft. Loudoun reservoir, Tennessee (USA)
TLDR
The results illustrate that assessing seasonally available prey from habitat utilized by lake sturgeon is important when investigating diet preference, and foraging mode of this recovering population in Ft. Expand
Diet of and Prey Availability for Reintroduced Juvenile Lake Sturgeon (Acipenser fulvescens) in Ft. Loudoun Reservoir, Tennessee
After fifteen years of reintroducing juvenile Lake Sturgeon (Acipenser fulvescens) in the Upper Tennessee River Basin, fisheries biologists are researching basic ecological traits of subsistentExpand
Host selection by larvae of a marine insect Halocladius variabilis: nutritional dependency or escape from predation?
TLDR
It is suggested that microhabitat selection by larvae of H. variabilis reveals important tradeoffs for growth and predator avoidance and that larval growth with other algal hosts was greater than with Elachista. Expand
18S rRNA metabarcoding diet analysis of a predatory fish community across seasonal changes in prey availability
TLDR
The utility of molecular diet analysis is demonstrated and how temporal variability in community composition adds complexity to predator–prey interactions is demonstrated. Expand
Documentation of Freshwater Mussels (Unionidae) in the Diet of Round Gobies (Neogobius melanostomus) within the French Creek Watershed, Pennsylvania
TLDR
The diet of round gobies in the French Creek watershed was document to determine whether consumption of native freshwater mussels was occurring and unionid consumption by the round goby in Pennsylvania that poses possible threats to native mussels in theFrench Creek watershed. Expand
Life-History Aspects of Fundulus stellifer (Southern Studfish) (Actinopterygii: Fundulidae) in Northern Georgia
TLDR
Fundulus stellifer (Southern Studfish) was studied using 12 monthly collections from Moore's Creek near Waleska, GA, and maximum age appears to be just over 2 years for both sexes, as the oldest specimens collected were estimated at 28 months of age. Expand
Evolution of the premaxillary fraenum and substratum in snubnose darters and allies (Percidae: Etheostoma).
TLDR
Ancestral state reconstructions and analyses of phylogenetic associations between presence of the premaxillary fraenum and preferred stream substratum were conducted in a clade of closely related darters (snubnose darters and allies), but a significant correlation between fraenum presence and substratum type across the phylogeny was not found.

Chironomus Newsletter on Chironomidae Research 27
The spatial distribution of chironomid communities in the littoral zone (0-20 m) of the western coast of the southern Baikal basin is investigated. The fauna is composed of 16 species and forms ofExpand
Taste attractiveness of different hydrobionts for roach Rutilus rutilus, bitterling Rhodeus sericeus amarus, and rainbow trout Oncorhynchus mykiss
TLDR
It is demonstrated that intraoral gustatory reception of food items follows two alternative behavioral stereotypes that are different from each other in the time during which food items are retained in the oral cavity and the number of manipulations during the perception process. Expand

TLDR
Investigation of the trophic ecology of the bayou darter Etheostoma rubrum of Bayou Pierre, Mississippi found seasonal variation in the diet was evidenced by relative occurrence of prey in stomachs and significant differences in feeding intensity across months. Expand
Habitat and food resource partitioning among four species of darters (Percidae: Etheostoma) in a southern Ontario stream
TLDR
Resource partitioning among four species of darters in an Ontario stream was investigated by determining diet and relative abundance in two habitats, and diets were closely related to morphology, but habitat utilization was not. Expand
Prey-Size Relationships and Feeding Tactics of Primitive Stream-Dwelling Darters
TLDR
Prey-size use and feeding tactics varied among three cooccurring darter species in the primitive subgenus Hadropterus (genus Percina) and interspecific differences in feeding tactics, as characterized by differences in prey size, diet breadth, and numbers of prey, also were reflected in slopes of ODI power curves.

Food Resource Partitioning and Selectivity by the Greenside, Rainbow, and Fantail Darters (Pisces: Percidae)
TLDR
Heavy reliance upon the abundant chironomid larvae by the darters may aid in reducing competition and increasing foraging efficiency, which may further decrease competition between these darters. Expand

It can be concluded that these fishes are opportunistic predators from ten Order 3 streams in the White River drainage of southern Indiana. Expand
Comparative Ecology of the Darters Etheostoma podostemone, E. flabellare and Percina roanoka in the Upper Roanoke River Drainage, Virginia
TLDR
Differences among the species in diet breadth are consistent with differences in their morphology, with E. flabellare having the greatest width of gape and widest diversity of prey taxa and size. Expand
Food Habits and Feeding Chronology of the Blackbanded Darter, Percina nigrofasciata (Agassiz), in Halawakee Creek, Alabama
TLDR
Daytime feeding peaks suggests that P. nigrofasciata are visual feeders, and dipteran larvae were the most important item in the diet throughout the year. Expand

TLDR
The data suggest that exposure to predators in a heterogeneous prey community is largely determined by tubedwelling behavior. Expand
Selective predation by a sculpin and a stonefly on two chironomids in laboratory feeding trials
TLDR
Sculpin and stonefly predators fed selectively on the larvae of the chironomids Paratendipes over Cricotopus in laboratory stream microcosms, indicating selectivity by visual feeding sculpin and tactile feeding stoneflies was most likely influenced by the difference in tube-dwelling behavior of the two prey types.
