In the face of global biodiversity decline, empirical evidence shows that local species richness has remained constant or even increased in many contexts. The discrepancies between global and local scales have led to a lively debate about our ability to capture changes in biodiversity. Instead of presenting empirical evidence fuelling this debate, I will center this presentation around new ideas and potential directions that could help resolve apparent inconsistencies in biodiversity trends:

• assessing the reliability of data across space and time
• relying on dynamic macroecological models that incorporate temporal changes at all scales
• taking into account the lagged responses of biodiversity and the influence of biotic interactions on the relationships between species and the environment.  

I will develop these three aspects, propose research directions and present exploratory work that I will be happy to discuss with anyone after the presentation.
