A review of the fossil record, they said, shows that rarity of previously abundant organisms is the only factor tied with certainty to the widespread ecological change observed across extinction boundaries, and because of this, the magnitude and extent of rarity may provide the best comparison of the current biotic crisis to those of the past.

To understand where interior forest has been lost and therefore where risks from forest fragmentation might be greatest, the researchers used global tree cover data to map the forests of 2000 and 2012 and examined the patterns of change across ecological regions and biomes.

A particular challenge for science is the growing evidence that social - ecological interactions across scales can generate regime shifts where profound and abrupt changes can occur in systems ranging from local ecosystems (such as lakes) to large biomes (such as the Arctic); from local communities (such as farming systems) to regional economic sectors (e.g., global fisheries).

The effectiveness of local adaptive strategies is uneven across the Arctic and there are large gaps in knowledge about why some communities do well, while others are more vulnerable to drivers of change, even when they share similar resources and ecological settings.

At best, changes of such magnitude would trigger dramatic re-organization of ecosystems across the globe that would play out over the next few centuries; at worst, extinction rates would elevate considerably for the many species adapted to pre-global warming conditions, via mechanisms described above (inability to disperse or evolve fast enough to keep pace with the extremely rapid rate of climate change, and disruption of ecological interactions within communities as species respond individualistically).

Ecodevelopmental theory consists of three overlapping components: (a) a social — ecological framework, based on the work of Bronfenbrenner (1979), that incorporates four levels of social context; (b) a developmental perspective emphasizing the changing nature of youth and families across time as a function not only of the current social context but also of changing conditions in the social context over time; and (c) a focus on social interactions between and among individuals in the youth's and family's social context.
