Background and aims – Sedum hispanicum acts as a pioneer species on the gypsum outcrops of Emilia Romagna region (Northern Italy). The species was studied in two Sites of Community Importance through a comparative phenological and genetic diversity analysis to provide insights into strategies adopted by the species for successful reproduction in th...
In August 2014, a stretch of riparian forest of the Savena river included in the SIC IT4050012 (near the town of Pianoro Vecchio - BO) was subject to clear cutting, with the declared aim to avoid any risks arising from possible floods. While the potential benefits of this intervention are still the subject of lively discussion, its negative impact...
Goniolimon italicum is an endemic species to central Apennines (Italy).
Here we provide the first report of heterostyly in this species. Two
morphological types were identified: an S-morph with stamen filaments
longer than gynoecia, stigmas with a papillate surface and
finely reticulated pollen grains with very small spinules (Type B); and
an L-mor...
Disturbances affecting flow and sediment transport regimes (e.g. dams, diversions, gravel mining, weirs, bank reinforcements, climate changes) can promote riverbed degradation and channel narrowing, and thus influence vegetation dynamics and composition. This study investigates the relationships and feedbacks between channel adjustments and riparia...
Landscape structure as well as local vegetation influence biodiversity in agroecosystems. A study was performed to evaluate the effect of floristic diversity, vegetation patterns, and landscape structural connectivity on butterflies (Lepidoptera: Papilionoidea and Hesperiidae), carabids (Coleoptera: Carabidae), syrphids (Diptera: Syrphidae), and sa...

Global climatic changes affect the phenology of plant species, particularly the flowering and the leaf unfolding. This study presents an analysis of the phenological behaviour of several woody species in relation to climatic data (temperature). Phenological data were recorded over approximately 3 decades in the city centre (University Botanical Gar...
The study highlights the changes occurred in several stands of Hyperico richeri-Vaccinietum communities of the high Emilian Apennines after 30 years after the first phytosociological and phenological surveys. In 2012 the same types of surveys were repeated in the original stands, with the aim to detect any change in vegetation structure as well as...
A phenological survey on Vaccinium heaths was repeated thirty years after the first observations, in the Northern Apennines (Italy). In line with the sampling method adopted in the earliest phases of the study, the phenological monitoring was undertaken in the same sites, located above the tree line between 1600 and 1800 m asl. The phenology of eac...
Erythronium dens-canis is an early-flowering understory lily of southern Europe with two leaves and a single flower, although a number of plants have only one leaf and do not flower. The leaves are mottled with silvery flecks and brown patches, that gradually vanish turning to a lively green color. The nature and function of this striking variegati...
This paper aims to describe the Italian PHEnology Network (IPHEN), a cooperative project started in 2006 with the aim of producing nationwide maps of analysis and forecast of plants phenological stages mainly used to satisfy the needs of agriculture, health and environmental care. Iphen is a data processing system composed of the following main seg...
Phenological scales used in the past were not standardized: in different countries different methods were followed and these are often still in use today: for example Italian Botanists usually make the phenological observations by means of the GFI key, adopted in 1993 by the Italian Phenological Gardens, or by Marcello’s Key. The comparability of d...
Phytophenological events involve flowering, fruiting, leaf flushing, and germination: it is conceivable that the timing of these events has important effects on survival or reproductive success of plants and on species range (Sakai, 2001; Chuine & Beaubien 2001). In this work, symphenological patterns of several submediterranean plant communities (...
Abstract
The rhythms of growth, flowering and fruiting of plant communities (symphenological patterns) are conditioned by synchronizing and asynchronizing factors. Phenological behaviours of species can be categorized into types and their synchrony or asynchrony (diversity) can be evaluated by numerical methods. Moreover, the phenological traits of...
Castanea sativa woods, one of the most widespread habitats of southern Europe, are included in the European Community Natura 2000 network within Sites of Community Importance (SCI). In the Northern Apennines, chestnut woods are mainly coppices derived from old chestnut orchards, and now abandoned. To describe the relationship between present chestn...
In Europe, in the last thirty years, the onset of spring has advanced (Estrella et al. 2009 Clim Res. 39). However the phenological shifts vary from one country to another and long time series are scanty in Southern Europe (Penuelas et. al. 2002, Glob. Change Biol.; Crepinsek et Kajfez 2003, Ann.Ser.Hist.Nat.13): for this reason we analyzed the dat...
The results of phenological observations in ageomorphologically differentiated area are shown.Phenological surveys were conducted on flowering andpollen emission of some common and widely diffusedGraminaceae species, using a 7-step key. By means ofmultiple regression analysis altitude,latitude, slope and exposure were identified as significantenvir...
The complex Pulmonaria saccharata-P. vallarsae has been studied by means of morphological, biometric and biosystematic analysis of dried and living specimens, in natural environments and under cultivation. Hydroponic cultures have been used to distinguish the effects of environmental conditions and of phenological phases in determining phenotypic p...
Vengono qui presentati i risultati di una indagine storica ed erbariologica volta a chiarire il significato del binomio P. saccharata Miller. I dati raccolti hanno permesso di designare un lectotipo, la cui origine risulta essere nord-europea (Belgio), e non Svizzera, come indicato nel protologo, né Italiana, come vuole una tradizione derivata dall...

... The aromatic genus Cistus consisting of around 25 species [6] used in traditional folk medicine to treat several diseases [7][8][9][10][11][12]. C. albidus (called Rock rose) is a small evergreen shrub distributed especially in the arid places (0 to 1400 m) of Mediterranean regions including Algeria [13]. In fact, many biological proprieties have been reported for C. albidus such as antioxidant, anti-inflammatory and antiviral activities [14][15][16] as well as its richness in essential oils [17][18][19][20][21][22]. ...

... Based on the data reported in this study, P. fasciculata populations maintain a mixed reproductive strategy in which gene flow and genetic drift act as alternative and complementary evolutionary mechanisms, allowing the species to colonize and persist in harsh environments characterized by soil salinity variations, like the Salse di Nirano or coastal wetlands. Similar results were also reported in Sedum hispanicum L. (Pezzi et al. 2017) growing in another extreme environment, such as the gypsum outcrops of northern Apennines. Codes and symbols of sampling sites follow Figure 1 and Table 1. ...
... Not only are chestnut dynamics affected by abiotic and biotic factors, with the latter ones becoming particularly relevant in the lack of active management (e.g. Romane et al., 1995;Conedera et al., 2000Conedera et al., , 2001Gondard et al., 2001;Paci et al., 2003;Pezzi et al., 2010;Pividori et al., 2006;Zlatanov et al., 2013;Müllerová et al., 2015). Many chestnut groves are strictly dependent on human use (Conedera et al., 2004b;Michon, 2011), so that their conservation is subordinated to a range of anthropogenic variables. ...

... However, if applied alone, each of these control tools is not sufficient to limit VMB spread, especially in case of high pest density suggesting that an integrated pest management (IPM) approach is essential to increase the effectiveness of these strategies (Cocco et al., 2020;Mansour et al., 2018;Vincent et al., 2012). The development of efficient monitoring systems is a crucial step in the evaluation of sustainable practices in contexts with clear anthropic impact such as agro-forestry ecosystems (Burgio et al., 2015;Campanaro et al., 2011;Marini et al., 2012;Pizzolotto et al., 2018). ...

... These observations suggest that although sand mining is likely to induce channel incision, there are range of often sitespecific, physical impacts arising from sand mining. The degree channel incision ranged considerably, from 3 to 6 m [14,15,16,17,18], up to 8 m [18,19] to up to maximum depth 30 m in Taiwan [20]. The channel incision resulting from these studies causes changes in channel platform and changes in longitudinal river profile which lead to flooding [20,21]. ...

... Character of alpine vegetation is also affected by land use changes. Of these, grazing cessation is of a particular importance, since it promotes expansion of reptile dwarf shrubs and some grasses, which leads to denser and more homogenized vegetation (Olofsson et al. 2001;Pakeman 2004;Baur et al. 2006;Kucharzyk and Augustyn 2010;Vassilev et al. 2011;Bonafede et al. 2014;Kyyak et al. 2014). Long-term grazing absence may lead to upward shift in timberline, since its current location is determined by historical anthropogenic influences rather than climate (Vorren et al. 1993). ...
... This fast flowering behavior has been reported previously (12), and it has been explained by a lower CH requirement. Phenological variation for "Tonda di Giffoni" and its pollinizers at different study sites agrees with previous findings, where synchronization between glomeruli opening and pollinizer's pollen release has been associated to genetic and cultural factors, photoperiod and solar radiation, among others (18,22,28,33). ...
... Exposure of species to such altered climatic regimes could result in modified behavior and adjusted phenology of plants (Gungula et al., 2003;Puppi, 2011;Monteith et al., 2015). ...
... The latter taxon is currently treated as a subspecies of the allopatric P. vallarsae because of striking morphological similarity (Cecchi & Selvi, 2015;Bartolucci & al., 2018). All these taxa are putatively different in features of summer basal leaves, such as shape, maculation, and hair pattern (Kerner, 1878;Bolliger, 1982;Puppi & Cristofolini, 1996). In addition, they also show differences in chromosome number: 2n = 28 in P. hirta, although 2n = 22 and 26 cytotypes have also been reported (Puppi & Cristofolini, 1996); 2n = 22 in P. apennina, although 2n = 26 has also been reported (Astuti & al., 2019); 2n = 22 in P. vallarsae (Puppi & Cristofolini, 1996). ...
