ecological speciation

How new species evolve is one of the most fundamental questions in biology. BBPP investigates the importance of ecological factors along the elevational gradient in driving population divergence using frogs as a model. By focusing on the influence of microclimate on species distributions, the interaction between genes and the microenvironment, and the phylogenetic and ecophysiological constraints of tropical ectotherms, this study sheds light on the minute interactive processes that prompt speciation.

consequences of climate change on amphibians

Understanding how temperature affects amphibian populations is fundamental to predict the consequences of global climate change. Global mean surface temperatures are projected to rapidly increase, and precipitation differences between wet and dry seasons are likely to become more pronounced. BBPP investigates the capacity of the Bioko amphibians to metabolically cope with ongoing climate change and their ability to either tolerate, move, or adapt to new environmental conditions.
