Arapaima may be closer to extinction
Arapaima, or Pirarucu, may be closer to extinction than previously thought and current procedures for ensuring the sustainability of their populations are insufficient to protect them from decline, according to a study by conservation biologist Leandro Castello and ichthyologist Donald Stewart.
Tropical plant species face an inherently high extinction risk due to small populations and restricted ranges relative to temperate species, reports research published in PLoS ONE.
