ABSTRACT A primary question for researchers in the field of conservation science concerns fragmentation biodiversity‐supporting habitat. Key debates revolve around relevance habitat composition and configuration outcomes. Central to this debate is measurement delineation patch, which informs fragmentation‐related metrics their evaluation. Despite need quantify model fragmentation, patch concept itself has been subject criticism concerning its ability adequately reflect heterogeneity resource distributions complex landscapes. In paper, we present continuity‐contiguity problem, one fundamental challenges related space, discuss implications fragmentation‐biodiversity research. We outline potential contribution recent developments spatial‐ecological methods leveraging uncertainty modelling process address four common issues concept: gap‐crossing multi‐variate delineation, interior‐edge transitions parameterise as both a discrete continuous spatial entity. conclude with several recommendations studies on outcomes where problem may influence research process.
