Antelope grass (Echinochloa pyramidalis) is an African grass species used for cattle grazing in Mexican wetlands. It has been introduced because of its tolerance to flooding and is now a widespread invasive. In this work, we present the advances of a freshwater marsh restoration project represented by bulltongue (Sagittaria lancifolia) but invaded by antelope grass. This project began in 2007 with the goals of eliminating antelope grass and other problematic species, increasing the cover of the native vegetation, and recovering habitat for waterfowl. Two sets of controls were established (in the remaining marsh and the inundated grassland) along with three other managed sites (variations of clipping by hand, drowning the cut plants, burning, covering with black plastic, or selectively applying herbicide). With two years of restoration activities, the antelope grass was almost completely eliminated, remaining only in one control set. The dry conditions of 2009 have favored the resprouting of the invader, but it still has low cover values. Pickerelweed (Pontederia sagittata), cattail (Typha domingensis), and bulltongue have appeared with high cover values in most of the quadrats in almost all sites. Plant species richness has increased with time. Amphibians and reptiles have varied through time but are showing a slight increasing trend.
We describe a new species of plethodontid salamander of the genus Pseudoeurycea from the Sierra de Zongolica, Veracruz, Mexico. The new species is distinguished from all other species in the genus by morphological and genetic features and by coloration. Based on a mtDNA phylogeny, the new species belongs to the Pseudoeurycea juarezi group and is most closely related to P. ruficauda from the Sierra Mazateca in northern Oaxaca. The newly described salamander increases the number of species of plethodontid salamanders from Veracruz to 43 and those recognized from Mexico to 140.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
