| Popis: | This paper presents data regarding conservation biology of Chionodoxa lochiae and Scilla morrisii; two threatened endemic plants of Cyprus, which are included as priority species in Annex II of the Habitats Directive. The population size and geographical distribution of the species were monitored for three years. C. lochiae was recorded in ten locations and S. morrisii was recorded in five locations. C. lochiae occurs in Pinus forests with/without Quercus alnifolia understory or in forest margins and riparian vegetation with Platanus orientalis. Favorable habitat of S. morrisii is the understory of Quercus infectoria stands and the Pistacia terebinthus-Quercus coccifera-Styrax officinalis shrubs. The distribution pattern of the species seems to follow habitat availability. Fecundity and Relative Reproductive Success of C. lochiae were stable and low, while in S. morrisii were constantly high. The lack of pollinators seems to be the main cause of the low sexual reproduction of C. lochiae. The germination strategy for both species is dependent on temperature. Some of the seeds are dormant and dormancy is broken by nitrates. The investigation of certain aspects of the biology of the two species yielded the information needed to identify the critical aspects affecting their survival and to propose sound conservation measures. © 2015 The Authors. |
