Degradation influences equilibrium and non-equilibrium dynamics in rangelands: implications in resilience and stability by Lopez, Dardo Ruben, Cavallero, Laura, Willems, Priscila Mabel, Bestelmeyer, Brandon Thomas, Brizuela, Miguel Angel

“…The influence of external factors on internal regulation processes might depend on ecological state, and thus, on system resilience. We asked if well-conserved (reference) states have higher resilience to external factors than degraded states, considering the greater capacity for self-regulation expected of reference states. …”

Is local best? Examining the evidence for local adaptation in trees and its scale by Boshier, David, Broadhurst, Linda, Cornelius, Jonathan, Gallo, Leonardo Ariel, Koskela, Jarkko, Loo, Judy, Petrokofsky, Gillian, St Clair, Bradley

“…The review will examine existing data (published and unpublished) in the context of the scale of local adaptation, with the results being presented in two formats: (a) relating survival, performance of provenances (classified by seed zone/provenance region of origin) to seed zone/provenance region of the planting site; (b) plotting survival, performance provenances against the distance (Euclidean/ecological) between the provenance and the trial site.…”
