Centres of origin: do they exist, can we identify them, does it matter? (original) (raw)

This workshop focused on identifying "centres of origin" for classical biocontrol agents, examining relevant biogeographical and molecular genetic methods. It highlighted conceptual frameworks and challenges in determining native ranges, centres of origin, and diversification, advocating for comprehensive sampling of native ranges as a more effective strategy for biocontrol agent selection. Discussions suggested that while identifying centres of origin can be useful for prioritizing surveys, greater clarity is needed on its implications in biological control.
