Niche width collapse in a resilient top predator following ecosystem fragmentationCraig A Layman
Marine Sciences Program, Department of Biological Sciences, Florida International University, 3000 NE 151st St, North Miami, FL 33181, USA
Ecol Lett 10:937-44. 2007
..Collapsed niche width reflects a homogenization of energy flow pathways to top predators, likely serving to destabilize remnant food webs and render apparently resilient top predators more susceptible to extinction through time...
