Current and potential ant impacts in the Pacific region
Lloyd L. Loope, Paul D. Krushelnycky
2007, Proceedings of the Hawaiian Entomological Society (36) 69-73
Worldwide, ants are a powerful ecological force, and they appear to be dominant components of animal communities of many tropical and temperate ecosystems in terms of biomass and numbers of individuals (Bluthgen et al. 2000). For example, ants comprise up to 94% of arthropod individuals in fogging samples taken from...

David A. Boughton, Peter B. Adams, Eric Anderson, Craig Fusaro, Edward A. Keller, Elsie Kelley, Leo Lentsch, Jennifer L. Nielsen, Katie Perry, Helen Regan, Jerry Smith, Camm C. Swift, Lisa Thompson, Fred Watson
2007, Report, NOAA Technical Memorandum NMFS
Recovery planning for threatened and endangered steelhead requires measurable, objective criteria for determining an acceptably low risk of extinction. Here we propose viability criteria for two levels of biological organization: individual populations, and groups of populations within the SouthCentral/Southern California Coast Steelhead Recovery Planning Domain. For populations, we adapt criteria...
