Abstract
To estimate the vulnerability of small isolated populations of rare species, it is necessary to study their population biology (Schmid & Matthies 1994). Besides dispersal, germination, and seedling establishment, generative reproduction plays an important role in ensuring population survival. Usually, the reproduction rate of a population depends on the amount of resources available in its habitat (Chiariello & Gulmon 1991). In small isolated populations, reproduction can be reduced (as a part of reduced fitness caused by inbreeding depression; Watson et al. 1994). Clegg & Brown (1983) and Soule (1980) point out that this is the most important factor which decreases the probability of population survival. The purpose of this study is to examine whether or not the reproduction rate is influenced by population size. Therefore, Muscari tenuiflorum was selected as a rare species in the pophyry hill landscape Northwest of Halle.
