Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests
2019
Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…
Recent and new taxonomic acquisitions in some native genera of Asteraceae from southern Italy and Sicily
2021
After a brief review of the recent acquisition in some native genera of family Asteraceae from southern Italy and Sicily, a new endemic species of Anthemis (sect. Hiorthia) is described from Sicily and named Anthemis parlatoreana. The locus classicus of the new taxon, falling in the NW Tyrrhenian coast of the island (Castellammare del Golfo, Trapani), coincides with that of Ptilostemon greuteri, another endemic very rare species of the Sicilian flora. Data on the morphology, distribution, ecology and conservation status of the new species are provided. The taxonomic relationships with the other Sicilian taxa of the same section, in particular A. cupaniana, are also analyzed. The simultaneou…
The genus Taraxacum (Asteraceae) in Italy. III. A new species of T. sect. Erythrocarpa from Sicily
2009
Taraxacum sect. Erythrocarpa is reported for the first time for Sicily. After field, herbarium and laboratory studies, a new species belonging to that section is described as new to science: T. garbarianum (2n = 32). Morphological, cytotaxonomical and distributional data are illustrated and discussed.
