Range Extension and Status Update for the Oklahoma Cave Crayfish, Cambarus tartarus (Decapoda: Cambaridae)

The range of the single-site endemic cave crayfish, Cambarus tartarus, is expanded to an additional cave system (Long's Cave), but is still restricted to the Spavinaw Creek watershed within Delaware County, Oklahoma. Censuses of these 2 populations in 2001 and 2004 produced record high counts:...

Zusammenfassung:The range of the single-site endemic cave crayfish, Cambarus tartarus, is expanded to an additional cave system (Long's Cave), but is still restricted to the Spavinaw Creek watershed within Delaware County, Oklahoma. Censuses of these 2 populations in 2001 and 2004 produced record high counts: 17 individuals in January-Stansbury Cave and 63 in Long's Cave. January-Stansbury Cave, with at least 52 species of animals, is the most species-rich subterranean habitat in Oklahoma to date. Conservation activities are summarized. Cambarus tartarus remains extremely vulnerable to degraded habitat quality, and further protection is recommended. /// La distribución del camarón de agua dulce Cambarus tartarus, endémica de un sólo sitio, se extiende a un sistema de cuevas adicionales (Long's Cave), pero continúa restringida a la cuenca Spavinaw Creek en el condado de Delaware, Oklahoma. Los censos de estas dos poblaciones en el 2001 y 2004 produjeron records altos de conteos: 17 individuos en January-Stansberry Cave y 63 en Long's Cave. January-Stansberry Cave, con al menos 52 especies de animales, es la cueva más rica en especies en Oklahoma hasta la fecha. Se resumen actividades de conservación. Cambarus tartarus permanece extremadamente vulnerable a la degradación de la calidad del hábitat, y se recomienda más protección.
