Adaptation to marginal habitats [PDF]

open access: yesAnnual Review of Ecology, Evolution, and Systematics, 2008
The ability to adapt to marginal habitats, in which survival and reproduction are initially poor, plays a crucial role in the evolution of ecological niches and species ranges. Adaptation to marginal habitats may be limited by genetic, developmental, and

Forest tree Marginal Populations in Europe - Report on the state of knowledge on forest tree marginal and peripheral populations in Europe [PDF]

open access: yesAnnals of Silvicultural Research, 2018
Marginal/peripheral (MaP) forest populations exist at the edge of species ranges, and may contain unique genetic diversity arising from adaptation to the adverse and unusual in the regions which they inhabit.

Adaptive margins for online adaptive radiotherapy [PDF]

open access: yesPhysics in Medicine & Biology, 2022
Abstract Objective. In online adaptive radiotherapy a new plan is generated every fraction based on the organ and clinical target volume (CTV) delineations of that fraction. This allows for a planning target volume margin that does not need to be constant over the whole course of treatment, as is the case in ...
