Species distribution of the Granular Poison Dart Frog (Oophaga granulifera) in Costa Rica

Started Mar. 8, 2024

Abstract or project description

This study aims to determine potential distribution and habitat suitability of the O. granulifera by developing a species distribution model (SDM) to analyze the effects of climate change on the species between the present and the future (years 2061-2080). I collected occurrence records of O. granulifera from the Global Diversity Information Facility (GBIF) database and 19 climatic variables from the WorldClim database to produce a generalized linear model (GLM)—the model aimed to predict the effects of present and future climatic variables on the species distribution of O. granulifera. The SDM showed increased areas of suitable habitat from the present to the future, indicating that climate change may have no significant negative effects on the species distribution.
