Using ecological niche models and niche analyses to understand speciation patterns: the case of sister neotropical orchid bees. [PDF]
PLoS ONE, 2014 The role of past connections between the two major South American forested biomes on current species distribution has been recognized a long time ago. Climatic oscillations that further separated these biomes have promoted parapatric speciation, in which
