Why do several small patches hold more species than few large patches? by Fahrig, Lenore, Storch, David

“…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…”

Rethinking patch size and isolation effects: the habitat amount hypothesis by Fahrig, Lenore

“…I challenge (1) the assumption that habitat patches are natural units of measurement for species richness, and (2) the assumption of distinct effects of…”

Patch‐scale edge effects do not indicate landscape‐scale fragmentation effects by Fahrig, Lenore

“…Negative landscape‐scale fragmentation effects are often inferred from negative patch‐scale edge effects. I tested this cross‐scale extrapolation using two…”

Are ecologists conducting research at the optimal scale? by Jackson, Heather Bird, Fahrig, Lenore

“…Aim: The spatial extent (scale) at which landscape attributes are measured has a strong impact on inferred species-landscape relationships. Consequently,…”

The disproportionately high value of small patches for biodiversity conservation by Riva, Federico, Fahrig, Lenore

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

The effects of human‐altered habitat spatial pattern on frugivory and seed dispersal: a global meta‐analysis by Cazetta, Eliana, Fahrig, Lenore

“…Seed dispersal by frugivorous animals is important for plant mobility, regeneration and persistence. Human‐caused landscape change is thought to disrupt seed…”

Landscape context affects genetic diversity at a much larger spatial extent than population abundance by Jackson, Nathan D, Fahrig, Lenore

“…Regional landscape context influences the fate of local populations, yet the spatial extent of this influence (called the "scale of effect") is difficult to…”

Why are some animal populations unaffected or positively affected by roads? by Rytwinski, Trina, Fahrig, Lenore

“…In reviews on effects of roads on animal population abundance we found that most effects are negative; however, there are also many neutral and positive…”
