20.500.12556/DiRROS-16503 Contrasting responses of alien and ancient forest indicator plant species to fragmentation process in the temperate lowland forests Fragmentation is one of the major threats to biodiversity. In a fragmented landscape, forest specialists are losing suitable forest habitats with specific site and microclimate conditions, which results in their local extinction. Conversely, the invasion of alien species is facilitated by open forest areas and increased boundaries between forest fragments and adjacent land. We studied the effect of fragmentation in terms of fragment size impact on overall plant species richness and on selected ecologically important groups' richness, composition, and diversity. We surveyed vegetation in the interior of 47 fragments of various sizes and one unfragmented reference forest. Our results reveal that the effect of fragmentation is complex and differs for studied plant groups. Decreasing fragment size negatively affects the overall plant richness and richness of native and ancient forest indicator plants as well as their diversity, while the effect is positive for alien plants. The highest proportion of ancient forest indicator plant species and the lowest proportion of alien plants in the unfragmented forest underline the great conservation value of forest fragments. At the same time, our results reveal that large and diverse forest ecosystems are susceptible to biological invasions as well. forest fragment indicator plants invasion diversity habitat modification habitat conservation true false true Angleški jezik Ni določen Neznano 2023-05-15 13:01:30 2023-05-15 13:01:33 2023-05-16 03:34:42 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Opis vira z dne 8. 12. 2022; Št. članka: 3392; 13 str. iss. 23 Vol. 11 Dec. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-12-01 581.524.2 2223-7747 10.3390/plants11233392 132812803 https://www.mdpi.com/2223-7747/11/23/3392 1 2a04b308-f2ff-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22283 RAZ_Sipek_Mirjana_2022.pdf RAZ_Sipek_Mirjana_2022.pdf 1 BDAECAEC5FEE8297FD2C601740B0741B 6a94f43142fa2cfd25127951d40971d71a5587771ac931955fccc7d4a90153a3 468df2e7-f2ff-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22284 Gozdarski inštitut Slovenije 0 0 0
