Dating of the Devils Hole Calcite Vein

Dating of the devils hole calcite vein.

et al. (2) present a long, continuous, highresolution climate record extracted from a calcite vein in Devils Hole, Nevada. If their dating is accurate, the record appears to contradict the Milankovitch hypothesis (3). Dating of subsamples of the vein was done with the use of well-established principles of 230Th dating (4) and with recently developed techniques for precise measurement of 230Th a...

Population ecology and monitoring of the endangered Devils Hole pupfish

We assessed four potential sources of error in estimating size of the population of Devils Hole pupfish (Cyprinodon diabolis); net, time of day, diver, and order of diver. Experimental dives (3/day) were conducted during 4 days in July 2009. Effects of the four sources of error on estimates from dive surveys were analyzed using a split-split plot ANOVA. Diver and order of diver had no significa...

The California Current, Devils Hole, and Pleistocene climate.

Herbert et al. (1) are to be commended for their convincing and important correlation of midto late-Pleistocene California Current sea surface temperatures (SSTs), California coastal vegetation, and the paleotemperature record in vein calcite at Devils Hole, Nevada. Their intriguing notion linking California Current SSTs and the Laurentide ice sheet, however, is open to question, as is their as...

Digging the pupfish out of its hole: risk analyses to guide harvest of Devils Hole pupfish for captive breeding

The Devils Hole pupfish is restricted to one wild population in a single aquifer-fed thermal pool in the Desert National Wildlife Refuge Complex. Since 1995 the pupfish has been in a nearly steady decline, where it was perched on the brink of extinction at 35-68 fish in 2013. A major strategy for conserving the pupfish has been the establishment of additional captive or "refuge" populations, bu...
