This study contributes to the natural history of darters
Mississippi's Pascagoula River drainage is home to the last known surviving populations of the pearl darter
(Percina aurora), a small freshwater fish that measures just two-and-one-half inches long.
These alga are generally confined to larger substrates (Hynes 1970) and may be a contributing reason why darters
select riffles for their habitat.
We compared differences in density and mean length of fountain darters
by type of habitat, as well as differences in water quality, using a non-parametric Kruskal-Wallis test followed by a Mann-Whitney U-test post-hoc comparison with a Bonferroni adjustment (P < 0.
A total of 313 stripetail darters
were found at 17 sites and 68 spottail daters were found at 13 sites (Table 1; Table 2; Figure 1; Figure 2).
He recognised it as a red-veined darter
, a rare visitor from southern Europe never previously recorded in the area.
Clean gravel shoals were thought to define its distribution in the Little Tennessee River (starnes, 1977), Imostoma darters
typically live for three years and occasionally into a fourth year (Etnier and Starnes, 1993).
The Niangua darter
(Etheostoma nianguae), a Missouri fish, became a threatened species in 1985 when reservoir construction blocked upstream movement and sent it into decline.
After the Waterworks Dam was removed in 1998, for example, the number of native species, such as darters
and smallmouth bass, rose from 11 to 26.
Brazile best known as campaign manager for former Vice President Al Gore's 2000 presidential campaign, is urging African American leaders to run as favorite sons and darters
in various states' presidential primaries to lock up as many delegate votes as possible before the Democratic Party convention assembles in Boston to pick nominees.
A reproducing population of goldstripe darters
was found in Needham Pond (N 31[degrees] 28.
I spoke of the indicator function played by endangered species in this and other cases, suggesting to the authors that snail darters
were canaries in the coal mine--a vivid concept now relatively common--that I thought they should acknowledge in their analysis of endangered species policy.
A lot of the angry debate and near strokes engendered by debate over spotted owls, snail darters
, and red-cockaded woodpeckers were futile if the simple premise of this book is correct.
The population of darters
on the base has improved dramatically in response to these habitat improvement efforts.
Due to overlap in use of habitat between snails and fountain darters
, we assessed whether native and nonnative snails consume eggs of fountain darters
, and if so, are there differences in rates of consumption among the snails?
