Dario neela, a new species of badid fish from the Western Ghats of India (Teleostei: Percomorpha: Badidae)

Dario neela, is described from a small tributary stream of the Kabini River in northern Kerala, India. It can be distinguished from congeners by the male colouration in life, which shows wide rims of iridescent blue in all median fins and the pelvic fin. It is further distinguished from all species of Dario, except D. urops by the number of abdominal vertebrae (14 vs. 11–13), and from all Dario species except D. urops and D. huli by the presence of a conspicuous black blotch on the caudal-fin base. Dario neela is distinguished from D. urops by the absence of the horizontal suborbital stripe and presence of a series of up to eight black bars on the body; and from D. huli by 27–28 vertebrae and 27 scales in a lateral row and the absence of teeth from hypobranchial 3. Dario neela is genetically divergent from both Western Ghats congeners in the mitochondrial CO1 gene, showing an uncorrected p-distance of 5.9% with D. urops and 13.1% to D. huli.

An Ancestral Caddo Site on Mill Creek in Rusk County, Texas

Site RC–15 (the 15th site recorded in Rusk County by Jones) in Rusk County, Texas, in the Pineywoods, was identified by Buddy Calvin Jones during his wide–ranging survey investigations in East Texas in the 1950s–1960s. This ancestral Caddo site is on Mill Creek, a tributary stream in the mid–Sabine River basin, a few miles south of its confluence with Tiawichi Creek. The Oak Hill Village site (41RK214), a large ancestral Caddo settlement that was occupied between ca. A.D. 1150–1450, is on Mill Creek not far south of Site RC–15.

The first 25 years of the hydrology of the Onyx River, Wright Valley, Dry Valleys, Antarctica

ABSTRACTThis paper summarises the first 25 years of data on hydrological work carried out each summer on the Onyx River, Wright Valley, by summer teams of field hydrologists of the New Zealand Antarctic Research Programme. The assignment expanded from the single water-level recording weir site near Lake Vanda to a second site near the Wright Lower Glacier together with a number of tributary stream measurements that were installed as the programme progressed. This work was carried out together with Dry Valleys lake level and glacial measurements and is as of much historical as of scientific interest as it contains much inaugural Antarctic hydrology work.

The L. L. Winterbauer Site (41WD6), Wood County, Texas

The L. L. Winterbauer site (41WD6) is an ancestral Caddo habitation site in the Lake Fork Creek basin in the Post Oak Savannah of East Texas (Figure 1). It is situated along a small tributary stream that flows west into Lake Fork Creek, itself a tributary to the Sabine River, about 1.5 miles west of Quitman, the county seat of Wood County. The recovered artifacts from the investigations of the Winterbauer site indicate that the site was occupied during the Late Caddo period Titus phase, dated generally between ca. A.D. 1430-1680.

Black Bass Diversity: Multidisciplinary Science for Conservation

<em>Abstract</em>.—Movement and habitat use of Shoal Bass <em>Micropterus cataractae</em> were evaluated in the flow-regulated Chattahoochee River, Alabama–Georgia. Forty Shoal Bass were tracked using radio tags in a 2-km section of river between two impoundments. Movement of Shoal Bass in this population was low, and most fish never left the reach of river where shoal habitat existed. A few fish migrated approximately 10 km up a tributary stream during the spring to reach a large shoal complex, presumably to spawn. No fish were found in the downstream impoundment or associated tributary streams. Shoal Bass were most commonly found in areas with bedrock substrate and cover, especially in the spring. Use of a tributary for presumed spawning indicates that this population of Shoal Bass was less isolated than many others in the Chattahoochee River.
