TL;DR: It is concluded that the extinction of populations was at least partly due to stochastic processes, supported by the fact that in allspecies a considerable proportion of small populations survived and developed intolarge populations.

TL;DR: The bacterial community developed through successional stages, leading at the RNA level to almost stable community patterns within 21 days after flooding, which suggests that the community dynamics can be explained by the principles of r- and K-selection.

TL;DR: Study of reproduction and offspring performance in relation to population size in the declining self-incompatible perennials Primula veris and Gentiana lutea suggests that small populations may face an increased short-term risk of extinction because of reduced reproduction, and an increased long- term risk because they are less able to respond to environmental changes.

TL;DR: It is concluded that gene flow among natural populations is very limited and that reduced plant fitness in small populations of G. germanica most likely has genetic causes, and management should aim to increase the size of small populations to minimize further loss of genetic variation.

TL;DR: In this paper, the authors presented meadow-like arrays of different species richness and evenness but random species composition to lay people and asked them to estimate plant species richness, and rank the arrays by attractiveness.
