A new country record for the Guiana Shield endemic Amapasaurus tetradactylus is noted for Suriname. The only specimen was captured during a Rapid Assessment Program (RAP) of Conservation International in the upper Palumeu river, south Suriname. This range extension shows the presence of A. tetradactylus in yet another country of the Guiana shield. A range extension of 290 km southwards is noted for this new record.
Abstract. The submerged aquatic carnivorous plant Utricularia breviscapa is noted in Para District, 40 km south from Paramaribo, Suriname. This species was found in a swamp with predominantly Eleocharis sp. Utricularia breviscapa was already documented from Guyana and French Guiana, and the new record is the first from Suriname and provides more information on the distribution of this species. A range extension of 354 km from the nearest previously known occurrence is noted for U. breviscapa.
The fungal pathogen Batrachochytrium dendrobatidis (Bd) which causes that amphibian disease chytridiomycosis is expanding its worldwide range from an Asian origin, infecting amphibians in a growing number of countries. Modelling the potential range of this amphibian pathogen using environmental variables and presence data could advance our understanding of at-risk areas and species in locations with limited surveillance to date. We used a species distribution model to assess Bd habitat suitability in the three Guiana’s (Guyana, Suriname, and French Guiana) in South America. The model output showed that all three countries have substantial areas where Bd could grow and proliferate, and maximum temperature of the warmest month was the top predictor of suitable Bd habitat, inversely correlated with modeled Bd occurrence. Predicted Bd infection areas in Guyana and French Guiana were large and localized whereas possible sites in Suriname were more scattered throughout the country. The areas projected as potential suitable in Suriname were mostly high elevation regions. These results could help inform efficiencies for development of a proactive monitoring program that could alert managers of novel Bd outbreaks for focused mitigation actions to forestall the spread of this amphibian disease.
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.
