AbstractSeed germination and seedling recruitment are key processes in the life cycle of plants. They enable populations to grow, migrate, or persist. Both processes are under environmental control and influenced by site conditions and plant–plant interactions. Here, we present the results of a seed-sowing experiment performed along an elevation gradient (2000–2900 m a.s.l.) in the European eastern Alps. We monitored the germination of seeds and seedling recruitment for 2 years. Three effects were investigated: effects of sites and home sites (seed origin), effects of gaps, and plant–plant interactions. Seeds of eight species originating from two home sites were transplanted to four sites (home site and ± in elevation). Seed sowing was performed in experimentally created gaps. These gap types (‘gap + roots’, ‘neighbor + roots’, and ‘no-comp’) provided different plant–plant interactions and competition intensities. We observed decreasing germination with increasing elevation, independent of the species home sites. Competition-released gaps favored recruitment, pointing out the important role of belowground competition and soil components in recruitment. In gaps with one neighboring species, neutral plant–plant interactions occurred (with one exception). However, considering the relative vegetation cover of each experimental site, high vegetation cover resulted in positive effects on recruitment at higher sites and neutral effects at lower sites. All tested species showed intraspecific variability when responding to the experimental conditions. We discuss our findings considering novel site and climatic conditions.

Djamaluddin R. 2018. The mangrove flora and their physical habitat characteristics in Bunaken National Park, NorthSulawesi, Indonesia. Biodiversitas 19: 1303-1312. The mangrove forests of Bunaken National Park are among the most distinctive andunusual in Southeast Asia because of the species that the forests contain. This study investigated the identity and diversity of mangroveplants as well as physiographic factors and major physical processes of every type of sub-habitats. Seven surveys were conducted tocollect and identify mangrove species of the park. Sub-habitats where specimen was found, aspects related to tidal inundation, nature ofsoil, freshwater influence and topography were observed as well as major physical processes influencing the condition of each subhabitat.The results suggested that the park was floristically rich with at least 27 plant species and they were distributed over tenrecognized sub-habitat types in different composition and diversity. Ceriops zippeliana Blume, Lumnitzera racemosa Willd, Lumnitzeralittorea (Jack) Voigt., Sonneratia ovata Backer, and Camptostemon philippinense (Vidal) Becc. were found in Bunaken National Parkand their presence confirmed the broader distribution limit of these species within Indo-Malesia region. A special notice was for C.philippinense as the distribution limit of this is rarely reported.
