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. 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.

The article focuses on the diet and predation of Masticophis flagellum (Coachwhip) and Heterodon nasicus (Western Hog-nosed Snake), highlighting the various species that M. flagellum has been known to prey upon, as well as a newly reported case of H. nasicus being depredated by M. flagellum.

The article focuses on the American crocodile (Crocodylus acutus) captured during a crocodile spotlight survey of East Cape Canal, Everglades National Park (ENP) on December 15, 2008. The author says that the C. acutus with 416.7 cm total length (TL) was a large male crocodile with a distinct scute slip #225. Meanwhile, the crocodile #225 was first caught on August 9, 1986 in the Flamingo Boat Basin, ENP, representing the largest live capture of C. acutus in Florida. It states that the next longest time interval is for a male, measuring 384.9 cm TL from the same nest as crocodile #225. Furthermore, the recaptures of two C. acutus in ENP is noted to underline the significance of the long-term monitoring programs for Endangered and Threatened species recovery.
