Agriculture and development transform forest ecosystems to human‐modified landscapes.
Decades of research in ecology have generated myriad concepts for the appropriate …

To design robust protected area networks, accurately measure species losses, or
understand the processes that maintain species diversity, conservation science must …

Positive effects of habitat patch size on biodiversity are often extrapolated to infer negative
effects of habitat fragmentation on biodiversity at landscape scales. However, such cross …

Small habitat patches have been historically neglected in conservation, primarily because
extinction risk is higher in small patches. Nevertheless, sets of small patches usually harbor …

Island biogeography theory posits that species richness increases with island size and
decreases with isolation. This logic underpins much conservation policy and regulation, with …

In a review of landscape-scale empirical studies, Fahrig (2017a) found that ecological
responses to habitat fragmentation per se (fragmentation independent of habitat amount) …

Habitat loss is a primary threat to biodiversity across the planet, yet contentious debate has
ensued on the importance of habitat fragmentation 'per se'(ie, altered spatial configuration of …

Background The principle that a single large habitat patch should hold more species than
several small patches totalling the same area (SL> SS) is used by conservation agencies to …

Understanding how landscape characteristics affect biodiversity patterns and ecological
processes at local and landscape scales is critical for mitigating effects of global …

In this essay: I provide a brief history of habitat fragmentation research; I describe why its
“non‐questions”('Is habitat fragmentation a big problem for wildlife species?” and,“Are the …
