RED SWAMP CRAYFISH (PROCAMBARUS CLARKII) IN THE PECOS VALLEY, NEW MEXICO
Abstract Invasive species are a global threat to biodiversity, and their introduction can have large economic and ecological consequences. Red swamp crayfish (Procambarus clarkii) are known to be highly invasive and can alter ecosystem structure and function. We document a recent occurrence of P. clarkii in a Pecos River tributary, New Mexico, following removal of common carp (Cyprinus carpio), another highly invasive species, from recently restored aquatic habitat. Resumen Las especies invasoras son una amenaza global para la biodiversidad y su introducción puede tener grandes consecuencias económicas y ecológicas. Se sabe que el cangrejo rojo del pantano (Procambarus clarkii) es altamente invasivo y puede alterar la estructura y función del ecosistema. Documentamos la aparición reciente de P. clarkii en un afluente del río Pecos, Nuevo México, luego de la eliminación de la carpa común (Cyprinus carpio), otra especie altamente invasiva, del hábitat acuático recientemente restaurado.
期刊介绍:
The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
