Balancing biodiversity in a changing environment
A gap exists between our ability to communicate the ideas of biodiversity change to the general public, in large part due to a shortcoming in a standard vocabulary to describe key, elementary, concepts.
The paper goes on to clarify some of the conditions and events that lead to each of the above actions.

In particular, that many of these actions happen over variable time intervals, related to the concept of reaching equilibrium in the system and the various interactions that can delay that result.
Some resulting questions:
- Can indicators of biodiversity surplus or deficit in existing ecosystems be developed?
- Can early-warning signs be identified for imminent biodiversity decline owing to extinction-debt payoff?
- How precisely can immigration credit and immigration rates be estimated?
- What risks and benefits accrue if managers attempt to intervene to, for example, foster immigration via managed relocation and or to prevent local extinction by taking extraordinary measures, such as modifying the physical environment to maintain previous conditions?
