Distribution and conservation status of Bothrops asper (GARMAN, 1884) in Ecuador
Bothrops asper (GARMAN, 1884) was conceived as a species distributed below 1.500 m a.s.l. in the Pacific versant and adjacent coastal lowlands of Ecuador, with few or no records in certain areas (Azuay, Loja, Imbabura, Santa Elena Peninsula). However, a reassessment of literature records and new data from specimens deposited at the Laboratorio de Anfibios & Reptiles, Universidad San Francisco de Quito / Fundación Herpetológica Gustavo Orcés in Quito, Ecuador and at the National Museum of Natural History, Smithsonian Institution (Washington D.C., USA) confirms that this species has records in every province, zoogeographic zone, and most plant forma- tions along western slopes and Pacific lowlands of Ecuador (including the Santa Elena Peninsula) at altitudes between sea level to at least 1.720 m. A conservation status assessment indicates that B. asper should be classified under the Least Concern IUCN category because it has a wide distribution, and it is a common species capable of adapting to altered zones. However, we emphasize the general need for mid and long-term monitoring programs in order to better understand the situation of populations of the highly diverse tropical snake faunas.
