Abstract

Two of the so-called "copper mosses", Scopelophila ligulata and S. cataractae, are geographically widespread and disjunctive, but are rare throughout their ranges. The rarity of these species is generally presumed to be the result of their dependence on elevated levels of metallic ions, especially copper. Analyses of the substrates for populations of S. ligulata in the Appalachian Mountains of North Carolina indicate that copper is not present in abnormally high concentrations. The causes for the rarity of S. ligulata remains an unresolved problem. /// Два так называемых "медных мха", Scopelophila ligulata и S. cataractae, - географически широко распространены и дизъюнктивны, но они редко встречаются в областях распространения. Редкую встречаемость этих видов обычно считают результатом их зависимости от надземного уровня металлических ионов, специально от меди. Анализы питательной среды популяций S. ligulata в Аппалачах в Северной Каролине показывают, что медь там не встречается в ненормально высоких концентрациях. Причины редкой встречаемости S. ligulata остаются неразрешенной проблемой.
