Resumo O banco de sementes no solo é um dos mecanismos de regeneração natural que contribui para o surgimento de espécies em áreas florestais ou degradadas, no entanto, a composição de espécies pode ser influenciada pelo histórico de uso da terra, pela matriz em que o fragmento está inserido, entre outros. O objetivo dessa pesquisa foi avaliar a composição florística, abundância e ecologia morfofuncional de plântulas de espécies arbóreas encontradas no banco de sementes no solo em fragmento de Floresta Tropical. Foram retiradas amostras de solos e levadas para o viveiro florestal e cobertas por tela sombrite 70%. As plântulas emergidas foram contadas, identificadas e classificadas quanto à síndrome de dispersão, grupo sucessional e ecologia morfofuncional dos cotilédones. Emergiram 3.441 plântulas, em 14 famílias e 28 morfoespécies. Predominaram Miconia prasina e Cecropia pachystachya com 22,20 e 17,78%, respectivamente; a síndrome zoocórica com 64%; houve predominância de espécies secundárias iniciais, seguida de pioneiras. 78% das plântulas são do tipo PEF (fanero-epígeo-foliáceo). Embora o remanescente esteja inserido em uma matriz agrícola possui uma média riqueza de espécies arbóreas no banco de sementes, sendo a maioria das espécies classificadas como fanero-epígeo-foliáceo, demonstrando a dinâmica e capacidade de autorregeneração da área estudada. Abstract The seed bank in the soil is one of the mechanisms of natural regeneration that contributes to the emergence of species in forest or degraded areas, however, the composition of species can be influenced by the history of land use, by the matrix in which the fragment is inserted, among others. The objective of this research was to evaluate the floristic composition, abundance and morphofunctional ecology of seedlings arboreal species found in the soil seed bank in tropical forest fragment. Soil samples were taken and taken to the forest nursery and covered by shading screens 70%. The emerged seedlings were counted, identified and classified in terms of dispersion syndrome, successional group and morphological and functional ecology of cotyledons. 3,441 seedlings emerged in 14 families and 28 morphospecies. Miconia prasina and Cecropia pachystachya predominated with 22.20 and 17.78%, respectively; zoochoric syndrome with 64%; there were predominance of early secondary species, followed by pioneers. 78% of the seedlings are of the PEF type (phanero-epigeal-foliaceous). Although the remnant is inserted in an agricultural matrix, it has an average tree species richness in the seed bank, most species being classified as phanero-epigeal-foliaceous, demonstrating the dynamics and self-regeneration capacity of the studied area.

The active landslide Slano blato above Lokavec in the Vipava valley, Slovenia, is a complex phenomenon. The hinterland of the landslide consists of the large fossil block of Mala Gora that slid about 300 m down the slope of Mt. Čaven, and was tilted with respect to the slope. We presume that the corresponding failure surface is concavelyshaped. The block consist in its lower part of Eocene flysch beds and in its upper part of Triassic carbonate rocks that are thrust over the flysch. It is probable that due to gravitational slumping the flysch basement obtained a concave shape, that serves as a catchment structure for retaining the ground water. It slowly percolates throughthe crushed calcarenitic layers in flysch. According to available data the Slano blato was triggered in 1887 by earthworks, and in 2000 by natural erosion processes. The structural characteristics allow the assumption that movement occurs in crushed and weathered flysch beds that are percolated by a steady or periodical supply ofgroundwater from the structural reservoir in the Mala Gora fossil slumped block. Coexistence of the older structural and the younger active weathered material landslides can be observed also at other localities along the thrust front of the Trnovo and Hrušica (Nanos) nappe. Especially interesting in this respect are the Razdrto and Strane landslides.
