“…At a pH of 5.5, alkalinity falls to 105 zero and inorganic aluminium concentration rises to become toxic to many forms of 106 life, including almost all fish (Sutcliffe & Hildrew 1989). Such anthropogenic 107 acidification has profound ecological impacts, including the loss of many acid-108 sensitive species from all trophic levels (e.g.…”

“…Because of this, the ionic composition and pH of the environment are major physical factors limiting the distributions of organisms in aquatic habitats. For aquatic invertebrates in general, including larval insects such as Ephemeroptera and Trichoptera, species richness and population densities decline at lower habitat pH (Sutcliffe and Hildrew, 1989). Highly alkaline habitats also show limited biodiversity.…”

“…However, we found that the % EPT increased only modestly between 1967 and 2011 and that the difference was not statistically significant. Contrary to the presumption that the EPT index represents intolerant taxa, two of the dominant taxa in Tom's Run in both 1967 and 2011, Leuctra and Amphinemura, are moderately acid-tolerant (Sutcliffe and Hildrew, 1989;Dangles et al, 2004) and thus their numbers did not decline when the stream was polluted. In Tom's Run, metrics of abundance, biomass, richness, and diversity were sensitive indicies for detecting changes in water quality, but metrics based on species composition were insensitive indicators of improvement.…”
