20.500.12556/DKUM-97279 The hummocky meadow micro‑scale patchiness efect on the Eggleaf twayblade Neottia ovata (Orchidaceae) functional traits Regularly managed hummocky meadows represent a species-rich, distinct type of postglacial grassland communities, which appear on loose carbonate material. Such microreliefs are characterized by numerous humps and pits, i.e. convex and concave features of the surface. Little is known about how plants respond to environmental heterogeneity at such small spatial scales. Neottia ovata (Orchidaceae) is a member of the Eurosiberian, Boreo-temperate element. This species is a well documented habitat generalist, occupying a wide range of habitats ranging from lowlands to mountains and from wet to dry sites, often including anthropogenic habitats. The aim of the present study was to evaluate the efect of hummocky meadow micro-scale habitat patchiness, i.e. small-scale habitat heterogeneity on selected N. ovata functional traits. Across all generalized linear mixed models (GLMMs), plant micro-location on the slope of a hump, expressed as plant height on a hump index was the key predictor of the analysed functional traits. The specifc microlocation of N. ovata specimens on the meadow humps plays a vital role in the plant’s functional trait values; it also afects ftness and the percentage of pollinated fowers. Hummocky meadow micro-scale patchiness ofers interesting perspectives for further research. Protecting the remaining hummocky meadows contributes to the conservation of biodiversity of the fragile alpine environment. orchids hummocky meadows habitat micro-scale patchiness functional trait variability environmental parameters orhideje grbinasti travniki mikroskopska razpršenost habitata spremenljivost funkcionalnih lastnosti okoljski parametri Neottia ovata true false true Springer Angleški jezik Slovenski jezik Znanstveno delo 2026-02-26 10:21:41 2026-02-26 10:21:42 2026-02-27 03:17:44 0000-00-00 00:00:00 2026 0 0 15 str. št. 2, št. članka 93 Letn. 160 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2026-02-07 2026-02-20 582.581 269723139 10.1007/s44473-026-00111-x 1126-3504 RAZ_Pausic_Igor_2026.pdf RAZ_Pausic_Igor_2026.pdf 1 0A64843B9EB05DCC449410B125E591E4 3c8b04db8a412ad683116016057ce89455513b9a9179e74f5a31e45893a29e67 cc2418fe-12f4-11f1-94ed-00155d580e1a https://dk.um.si/Dokument.php?lang=slv&id=203918 https://doi.org/10.1007/s44473-026-00111-x 1 91a72043-12f4-11f1-94ed-00155d580e1a https://dk.um.si/Dokument.php?lang=slv&id=203917 Fakulteta za naravoslovje in matematiko 0 0 0
