In this paper are reported three new localities of Zeuneriana marmorata (Fieber, 1853), located in two different coast areas in Friuli Venezia Giulia Region. On June 2014 the species was found at the Isonzo mouth, near the village of Fossalon di Grado. On July 2016 Zeuneriana marmorata was discovered in two localities of Marano Lagoon, in the Stell...

... For each animal species, a crossing cost was assigned to each CORINE BIOTOPES (2017) habitat type depending on the ecology and habitat preferences of the animal. Costs ranged from 1 (the preferred habitat types) to 100 (extremely hostile habitat types, tending to act as barriers), and were assigned based on the existing literature [40][41][42][43][44] and expert opinion of local zoologists (including co-authors MDL and PZ). ...
Green infrastructure (GI) networks comprising multiple natural and artificial habitats are important tools for the management of ecosystem services. However, even though ecosystem services are deeply linked with the state of biodiversity, many approaches to GI network planning do not explicitly consider the ecological needs of biotic communities, which are often threatened by anthropic activities even in presence of protected areas. Here, to contribute in fill this gap, we describe an easy-to-apply, biodiversity-centric approach to model an ecological network as a backbone for a GI network, based on the ecological needs of a range of representative species. For each species, ideal habitats (nodes) were identified, and crossing costs were assigned to other habitat types depending on their compatibility with the species ecology. Corridors linking the nodes were then mapped, minimizing overall habitat crossing costs. We applied the method to the Isonzo–Vipacco river area in Northern Italy, highlighting a potential ecological network where nodes and corridors occupied 27% and 11.8% of the study area, respectively. The prospective of its conflicts with anthropic activities and possible solutions for its implementation was also discussed. Our method could be applied to a variety of situations and geographic contexts, being equally useful for supporting the protection of entire biocenoses or of specific sensitive species, as well as enhancing the ecosystem services they provide.
... Further localities and more extensive geographical information are listed in [8] and [9] from the collections of the Museo Civico di Storia Naturale di Venezia, Museo Civico di Storia Naturale di Trieste and La Greca Collection (presently at the Museo Civico di Storia Naturale di Milano). The last and most updated inventory of localities of the species is in [10]. Zeuneriana marmorata is listed as Endangered (EN) by IUCN [11], included in the European Red List of Grasshoppers, Crickets and Bush-crickets [12] and focus of two IUCN national action plans, one for Italy [13] and one for Slovenija [14]. ...
Correct management of protected areas is one of the key factors in biodiversity conservation. Routine surveys in Mincio Natural Park resulted in the finding of a population of Zeuneriana marmorata (Fieber, 1853), listed as EN (Endangered) by IUCN in the Red List of European Orthoptera. Other known populations were known only for NE Adriatic coast in Italy and inland in Slovenia. We assume that the current presence of this species is what remains of a larger metapopulation living in the wet habitats of the plains around the North Adriatic Sea. Causes of range fragmentation are supposed, current threats outlined and possible conservation actions proposed.
... Ochrilidia sicula (male), endemic to the sand dunes of Sicily, now in decline and endangered (photo B. Massa). At least 45 endemic taxa, within a total number of 188 species, are distributed in non-mountainous areas along the Italian peninsula (EI: see Table 1, cf. also Kleukers et al., 1997;Gomboc & Segula, 2005;Fanin et al., 2016), where they mostly occur in isolated, arid or semi-arid habitats (e.g., the non endemic genera Acrometopa, Poecilimon, Ephippiger, Eupholidoptera, Rhacocleis, Prionotropis, Oedipoda, Dociostaurus, and Chorthippus). ...
... 2) Mouth of the Isonzo River (Municipalits of Grado and Staranzano; Regional Nature Reserve Foce dell'Isonzo) (Fig. 11) In June 2014 a population was found south of Fossalon di Grado near the village of Punta Sdobba, at the mouth of the river Isonzo (right bank, locality "Caneo", Grado). In August 2016 the species was found in reed beds along the left bank of Isonzo too (near Punta Spigolo, Staranzano) (Fanin et al. 2016). ...
... It is not easy to establish precisely the area occupied by the species, because it is difficult to walk in the reeds as a result of the presence of flooded areas. 3) Lagoon of Marano (Fig. 13) In July 2016, the species was found in two areas of the Lagoon of Marano (Fanin et al. 2016). Three major subpopulations were found together with isolated singing males. ...
Wetlands belong to the most highly threatened habitat types on our planet. In Europe, many
wetlands have been destroyed or degraded by human activities, including drainage,
agricultural land use, industrialization, regulation and damming of river courses, pollution,
eutrophication, invasions of non-native species and other actions. In northern Italy, many
wetlands have disappeared and been replaced by intensive croplands or industrial areas,
leading to a drastic decline of many wetland species.
The Adriatic Marbled Bush-Cricket, Zeuneriana marmorata (Fieber, 1853), is a rare bush-
cricket species, which is found in a few wetlands in north-eastern Italy (Friuli Venezia Giulia)
and Slovenia. It has a loud and highly characteristic song, which creates a unique acoustic
atmosphere in the very few places where it still exists. The species occurs in coastal reed beds
(Fig. 1), where it is only found where the reed vegetation is not too dense and the water not
too saline. Only four populations of this species still exist with an estimated total of 3,000-
5,000 adult individuals per year (a very small number for an insect species). The entire
remaining habitat of this species has a size of 0.57 km² (57 ha) with only ca. 16 ha being left in
Italy. Z.
marmorata is quite sedentary and sensitive to habitat destruction.
Geoparks that adhere to the UNESCO Global Geoparks Network (GGN) traditionally present themselves to the community with a publication that illustrates their distinguishing features, which have enabled them to become a UNESCO Geopark.
This informative publication on the Classical Karst geopark is the business card with which this territory and its community present themselves to UNESCO GGN, visitors and citizens in general.
This is not the first work to illustrate the unique geology and geodiversity of this area, the natural environment and the rich cultural heritage of this border area between Italy and Slovenia. For several centuries the geology of the Classical Karst has been the subject of scientific studies and speleological explorations, which have enriched our knowledge of Karst and the specific environment of the area. This is, however, the first publication to consider the geological and territorial resources present across the entire area of the Classical Karst, from the point of view of geoparks, as an element encapsulating identity for the local community and as a tool for sustainable development.
It is an editorial work created within the framework of the Italy-Slovenia Interreg cross-border cooperation project "GeoKarst" and as part of the policy for the enhancement of geodiversity and geoparks promoted by the Autonomous Region of Friuli Venezia Giulia.
