Nonetheless, although they are mostly protected through several regulations, wetlands are affected by many negative factors that are leading to progressive deterioration of their conservation status. This circumstance is especially obvious in the Continental biogeographical region of Northern Italy, which is included in Piedmont and Lombardy on the left hydrographic side of the River Po. The goal of this study was to assess the main ecological drivers, i.e. the most important ecological factors, including pressures and threats, that shape negatively ecosystem dynamics, hence affecting conservation targets, and finally to suggest actions for counteracting them. Analyses were done at different scales, through bibliographic researches and site-specific data processing. As a result, we identified groups of ecological drivers, among which three were recognized as prevalent: a) the anthropic alteration of water levels; and b) the natural ecological succession in combination to c) the abandonment of traditional land use practices. The last two main ecological drivers were regarded as those to be counteracted by removing biomass (through digging, mowing, fire), because they may produce cascading effects and work against all the other ecological drivers. However, it is necessary to define a new reference framework based on pointing out conservation priorities at large scale (regional or supra-regional) and conservation actions at local scale, both focused on adaptive management.]</p> <p>&nbsp;</p> <p>[Article in Italian]</p> 2019-11-27T11:17:43+00:00 ##submission.copyrightStatement## An annotated key to the species of Gastridium (Poaceae) with distributional novelties to the Italian territory 2020-01-25T10:06:02+00:00 Anna Scoppola <p><em>Gastridium</em> is a Mediterranean-paleotropical genus of the Poaceae family, native to Italy. Species number and diversity were imperfectly known until recent taxonomic updates on morphological and molecular basis that enhanced our knowledge of this <em>taxon.</em> The present contribution provides a complete key of the genus, encompassing the four currently known closely related species, <em>G. lainzii,</em> <em>G. phleoides, G. scabrum</em>, and <em>G. ventricosum.</em> The essential features of panicle, spikelets, and florets are specified and briefly discussed. Revisions of ancient and recent herbarium specimens provided three Italian distributional novelties for <em>G. phleoides</em> concerning Liguria, Campania, and Puglia and two for <em>G. scabrum</em> concerning Liguria and Basilicata. In contrast, the distributional ranges of <em>G. scabrum</em> and<em> G. lainzii</em> in the W Mediterranean region remain poorly known and await further investigations.</p> 2019-11-04T11:39:04+00:00 ##submission.copyrightStatement## Marine and freshwater taxa: some numerical trends 2020-01-25T10:06:02+00:00 Semyon Ya. Tsalolikhin Aldo Zullini <p>Most of the freshwater fauna originates from ancient or recent marine ancestors. In this study, we considered only completely aquatic non-parasitic animals, counting 25 phyla, 77 classes, 363 orders for a total that should include 236,070 species. We divided these taxa into three categories: exclusively marine, marine and freshwater, and exclusively freshwater. By doing so, we obtained three distribution curves which could reflect the marine species’ mode of invasion into continental waters. The lack of planktonic stages in the benthic fauna of inland waters, in addition to what we know about the effects of the impoundment of epicontinental seas following marine regressions, lead us to think that the main invasion mode into inland waters is more linked to the sea level fluctuations of the past than to slow and “voluntary” ascents of rivers by marine elements.</p> 2019-10-24T09:37:50+00:00 ##submission.copyrightStatement## Vascular flora of Milan Malpensa airport (Lombardy, Italy). Part I: checklist 2020-01-25T10:06:03+00:00 Marco Martignoni Enrico Banfi Gabriele Galasso <p>Airport areas have, among flight infrastructures, large green spaces which, not having production purposes, are managed through interventions of minimal disturbance on habitats, with potentially positive effects on the conservation of biodiversity. The checklist of the vascular flora of the airport of Milan Malpensa is here presented. This airport extends for 12.44 km2 in the southwestern portion of the province of Varese (Lombardy, Italy) in the administrative districts of Cardano al Campo, Casorate Sempione, Ferno, Lonate Pozzolo, Samarate, Somma Lombardo and Vizzola Ticino. The collection campaigns were carried out between August 2010 and September 2018. The specimens collected are now kept in the herbarium facility of the Natural History Museum of Milan (MSNM). The floristic list was organized following the arrangement and the nomenclature of the recently published Italian flora checklists. It includes 395 taxa of specific and subspecific rank (9.35% of the entire flora of Lombardy) belonging to 247 genera and 72 families. The native taxa are 318, while the alien ones are 77. The native/aliens ratio is comparable to the one calculated at the regional level (4.10 vs. 4.42). The endemic contingent includes two taxa: <em>Centaurea nigrescens</em> subsp. <em>pinnatifida,</em> Italian endemic, and <em>Euphrasia cisalpina,</em> endemic to the Alps. The Malpensa airport is still the only site confirmed at the national level for <em>Lepidium heterophyllum</em> and, at the regional level, for <em>Festuca muralis</em> and <em>Euphrasia cisalpina.</em> The ecological characteristics and the data analysis will be discussed in a second contribution.</p> 2019-10-24T09:25:25+00:00 ##submission.copyrightStatement## Editor’s note 2020-01-25T10:06:04+00:00 Giorgio Chiozzi <p>Not available</p> 2019-06-11T00:00:00+00:00 ##submission.copyrightStatement## Haliplidae, Noteridae, Dytiscidae (Coleoptera) from Gabon (12th part).

This is principally due to a dearth of well-preserved specimens. Moreover, the type material of the species instituted by Stoppani has not been re-examined in recent publications. Therefore, a thorough search for the Stoppani Collection’s reference types in the storerooms of the Museo di Storia Naturale di Milano has been carried out. This investigation revealed that the gastropod types from Main Dolomite described by Stoppani had effectively been lost, possibly following an air-bombing raid hitting the museum during World War II. Consequently, we here describe only two specimens from the portion of the Stoppani Collection housed at the Museo Scientifico Naturalistico “A. Stoppani”, Venegono Inferiore (Varese, Italy). These two specimens were collected by Antonio Stoppani in Songavazzo (Bergamo, Italy) that he himself identified as one of the type localities. These particularly well-preserved specimens display characters useful for their possible attribution to the genus <em>Wortheniella.</em></p> 2019-03-18T11:48:51+00:00 ##submission.copyrightStatement## A pinnotheroid pea crab (Decapoda, Brachyura, Pinnotheridae), from the early Pliocene of Cassine (Alessandria, Piemonte, NW Italy) 2020-01-25T10:06:06+00:00 Giovanni Pasini Alessandro Garassino <p>A pinnotheroid pea crab (Pinnotheridae De Haan, 1833), is here reported from the Zanclean (early Pliocene) clays of a quarry located S-SW of Cassine (Alessandria, Piemonte, NW Italy).

Except <em>Monodaeus bortolottii</em> Delle Cave, 1988 (Xanthidae MacLeay, 1838), which is reported here for the first time in Miocene, all the other specimens have been assigned to species previously known in the Italian Miocene (Messinian s.l.), but never reported in this area. The report of <em>Galathea</em> cf. <em>G. weinfurteri</em> Bachmayer, 1950 (Galatheidae Samouelle, 1819) and <em>Medorippe ampla</em> Garassino, De Angeli, Gallo and Pasini, 2004 (Dorippidae MacLeay, 1838) enlarges the stratigraphic range of these Miocene species. This report enlarges our limited knowledge on the composition and distribution of the axiidean, anomuran, and brachyuran decapods during the early-middle Messinian before the evaporitic event in the Mediterranean Basin.</p> 2019-03-18T08:17:31+00:00 ##submission.copyrightStatement##
