	abstract = {Ten months after flooding lake Baciver, water levels were 5.5 m higher than the previous normal and the area formally occupied by the Isoetes population was reduced. All Isoetes originally present below 0.6 m died, and only plants standing between 5.8 and 6.1 m (new depth) survived. As irradiance decreased, remaining individuals produced fewer leaves, but their biomass production was higher, as leaf length increased in response to the diminished available irradiance. Because leaf mortality was excessive, regeneration capacity, population performance and dynamics were adversely affected. In 1992, no new production occurred in Isoetes lacustris individuals surviving after the winter. We suggest that low surface oxygen levels at the water column under the ice, and total anoxia below 6 m depth, caused the demise of the I. lacustris population in Lake Baciver.},

	abstract = {Structural (density and biomass), morphological and phenological characteristics of a population of Isoetes lacustris L. in a high mountain lake in the Pyrenees were studied. Changes in these parameters along a depth gradient can be used to distinguish a shallow water population (0.3-1.3 m depth) from a deep water population (1.8-2.3 m depth). Density of individuals decreased with depth, while biomass, size, size diversity and fertility showed the opposite pattern. The effect of ice-scour during winter together with a lower organic matter content in shallow areas are suggested as the main ecological factors responsible for these differences. Extremely high biomass values, when compared with North European populations of I. lacustris, seem to be related to a higher light availability in Pyrenean lakes. High rates of sedimentation causing burying of individuals and light depletion can explain the sharp, shallow lower boundary of the distribution of I. lacustris in Lake Baciver. {\textcopyright} 1993.},
