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 how microclimate influences species distribution at a fine scale, how gene-microenvironment interacts, and the phylogenetic and ecophysiological constraints of tropical ectotherms, this study helps to elucidate the spatial scale of adaptation, how gene flow is reduced in a micro-geographic scale, and the additional variables that are required beyond those applied at broader scales.

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 continue increasing, and precipitation differences between wet and dry seasons are likely to become more pronounced. Whether ectothermic species can metabolically cope with ongoing climate change will depend on the ability of species to either tolerate, move, or adapt to new environmental conditions. BBPP investigates whether amphibians on Bioko Island can metabolically cope with ongoing climate change and if they can adapt to new environmental conditions.
