Editing Habitat fragmentation (section)

==== Adaptation ====
In order for populations to evolve in response to natural selection, they must be large enough that natural selection is a stronger evolutionary force than genetic drift. Recent studies on the impacts of habitat fragmentation on adaptation in some plant species have suggested that organisms in fragmented landscapes may be able to adapt to fragmentation.<ref>{{cite journal |last1=Matesanz |first1=Silvia |last2=Rubio Teso |first2=María Luisa |last3=García-Fernández |first3=Alfredo |last4=Escudero |first4=Adrián |title=Habitat Fragmentation Differentially Affects Genetic Variation, Phenotypic Plasticity and Survival in Populations of a Gypsum Endemic |journal=Frontiers in Plant Science |date=26 May 2017 |volume=8 |pages=843 |doi=10.3389/fpls.2017.00843 |pmid=28603529 |pmc=5445106|doi-access=free |bibcode=2017FrPS....8..843M }}</ref><ref>{{cite journal |last1=Dubois |first1=Jonathan |last2=Cheptou |first2=Pierre-Olivier |title=Effects of fragmentation on plant adaptation to urban environments |journal=Philosophical Transactions of the Royal Society B: Biological Sciences |date=5 December 2016 |volume=372 |issue=1712 |pages=20160038 |doi=10.1098/rstb.2016.0038 |pmid=27920383 |pmc=5182434}}</ref> However, there are also many cases where fragmentation reduces adaptation capacity because of small population size.<ref>{{cite journal |last1=Legrand |first1=Delphine |last2=Cote |first2=Julien |last3=Fronhofer |first3=Emanuel A. |last4=Holt |first4=Robert D. |last5=Ronce |first5=Ophélie |last6=Schtickzelle |first6=Nicolas |last7=Travis |first7=Justin M.
