Final answer:
Mac Nally et al. (2008) examined the effects of climate change scenarios on four biodiversity 'currencies': species richness, phylogenetic diversity, endemism, and conservation status. Different scenarios can have varying impacts on these measures, highlighting the importance of considering multiple aspects when assessing the effects of climate change on biodiversity.
Step-by-step explanation:
In their study, Mac Nally et al. (2008) examined the effects of climate change scenarios on four biodiversity 'currencies': species richness, phylogenetic diversity, endemism, and conservation status. They found that different climate change scenarios can have varying impacts on these biodiversity measures. For example, in some scenarios, species richness may increase due to range expansions, while in others it may decrease due to habitat loss.
The study also highlighted the importance of considering multiple biodiversity measures when assessing the impacts of climate change. Each measure provides unique insights into the potential effects on biodiversity. For instance, phylogenetic diversity captures the evolutionary relationships among species and can help identify vulnerable lineages.
Overall, the study demonstrated that climate change scenarios can have complex and context-dependent effects on biodiversity, and considering multiple 'currencies' is crucial for a comprehensive understanding of these impacts.
