Data from: Testing macroecological abundance patterns: the relationship between local abundance and range size, range position and climatic suitability among European vascular plants

Aim: A fundamental question in macroecology centres around understanding the relationship between species' local abundance and their distribution in geographic and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (1) the abundance-range size relationship, (2) the abundance-range centre relationship, and (3) the abundance-suitability relationship. Location: Europe Taxon: Vascular plants Methods: Distribution range maps were extracted from the Chorological Database to derive information on the range and niche sizes of 517 European vascular plant species. To estimate local abundance, we assessed samples from 744,513 vegetation plots in the European Vegetation Archive, where local species' abundance is available as plant cover per plot. We then calculated the 'centrality', i.e. the distance between the location of the abundance observation and each species' range centre in geographic and climatic space. The climatic suitability of plot locations was estimated using coarse-grain species distribution models (SDMs). The relationships between centrality or climatic suitability with abundance were tested using linear models and quantile regression. We summarized the overall trend across species' regression slopes from linear models and quantile regression using a meta-analytical approach. Results: We did not detect any positive relationships between a species' mean local abundance and the size of its geographic range or climatic niche. Contrasting yet significant correlations were detected between abundance and centrality or climatic suitability among species. Main conclusions: Our results do not provide unequivocal support for any of the relationships tested, demonstrating that determining properties of species' distributions at large grains and extents might be of limited use for predicting local abundance, including current SDM approaches. We conclude that environmental factors influencing individual performance and local abundance are likely to differ from those factors driving plant species' distribution at coarse resolution and broad geographic extents.

Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests

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 indices, open-habitat species and Carabus nemoralis responded positively, and forest species, Leistus terminatus and Pterostichus oblongopunctatus responded negatively, to the undergrowth removal. Regarding plants, generalists, Maianthemum bifolium, Rubus saxatilis and Sorbus aucuparia responded positively, and forest species, Geranium sylvaticum, Oxalis acetocella and Vaccinium myrtillus responded negatively, to the undergrowth removal. (2) Edge proximity had little effect on both plants and carabids. However, open-habitat carabids were less abundant and less speciose, and the plants Oxalis acetocella, Trientalis europaea and Rubus saxatilis had higher cover, 10−20 m from than right at the edge. (3) Plant (but not carabid) community responded to the undergrowth removal but not to the edge proximity. While managing urban forests, we recommend an avoidance of undergrowth removals at sites that host rare or threatened forest-associated flora and fauna.

Data from: Altitude effects on spatial components of vascular plant diversity in a subarctic mountain tundra

Environmental gradients are caused by gradual changes in abiotic factors, which affect species abundances and distributions, and are important for the spatial distribution of biodiversity. One prominent environmental gradient is the altitude gradient. Understanding ecological processes associated with altitude gradients may help us to understand the possible effects climate change could have on species communities. We quantified vegetation cover, species richness, species evenness, beta diversity, and spatial patterns of community structure of vascular plants along altitude gradients in a subarctic mountain tundra in northern Sweden. Vascular plant cover and plant species richness showed unimodal relationships with altitude. However, species evenness did not change with altitude, suggesting that no individual species became dominant when species richness declined. Beta diversity also showed a unimodal relationship with altitude, but only for an intermediate spatial scale of 1 km. A lack of relationships with altitude for either patch or landscape scales suggests that any altitude effects on plant spatial heterogeneity occurred on scales larger than individual patches but were not effective across the whole landscape. We observed both nested and modular patterns of community structures, but only the modular patterns corresponded with altitude. Our observations point to biotic regulations of plant communities at high altitudes, but we found both scale dependencies and inconsistent magnitude of the effects of altitude on different diversity components. We urge for further studies evaluating how different factors influence plant communities in high altitude and high latitude environments, as well as studies identifying scale and context dependencies in any such influences.

List of vascular plant species found in the "Natural Reserve of Monte Catillo" (central Italy)

This list of vascular plant species was developed based on the work carried out for the definition of the Reserve planning (Provincia di Roma, 2006).  Between 2020 and 2023 floristic surveys and vegetation plots led to the integration of this original list, whose nomenclature was standardized according to Bartolucci et al. (2018). Compared to the 365 species reported in the original list (Provincia di Roma, 2006), 520 species are now listed, i.e., 155 more than in the previous list. Interestingly, among the added species there are two non-native species for which eradication could be considered, i.e., Agave filifera and Aloe maculata, and several previously undetected orchid species, e.g., Cephalantera longifolia, Ophrys crabronifera, Ophrys incubacea.   References Bartolucci, F., Peruzzi, L., Galasso, G., Albano, A., Alessandrini, A., Ardenghi, N.
