“…Since the early 1990s, both yabby and redclaw (C. destructor and C. quadricarinatus, respectively) are intensively farmed in Italy (D'Agaro et al, 1999). Scalici et al (2009) reported an established population in the Natural Preserve of "Laghi di Ninfa" (central Italy). The animals were probably introduced at the end of the 1980s to foster an experimental aquaculture.…”

“…Advances in astacological research since the publication of the Atlas allowed filling at least some of these gaps (e.g., Trožić-Borovac, 2011;Simić et al, 2008), and also led to re-assessment of species identity and diversity of some of the alien species present in European waters (e.g., Chucholl and Daudey, 2008;Filipová et al, 2011). Furthermore, expansion of invasive species was well documented for some regions e.g., Italy (Aquiloni et al, 2010) and Romania (Pârvulescu et al, 2009, and isolated populations of various recently introduced alien species were discovered in many European countries (e.g., Scalici et al, 2009;Jaklič and Vrezec, 2011;Chucholl et al, 2012). Some of these changes that became known since the publication of the Atlas were reflected in the comprehensive review by , which nevertheless re-used the original 2006 maps.…”

Key-words: crayfish distribution, indigenous species, invasive species, native range, mapsRecently published astacological studies substantially improved available data on distribution of crayfish in various European regions. At the same time, spread of invasive species has been recorded, additional nonindigenous species became established in various countries, and losses of populations of native species due to crayfish plague and other negative factors were observed. We overview recent advances in this knowledge, and provide updated colour maps of the distribution of all crayfish species present in Europe. These maps are originally based on the data from the Atlas of Crayfish in Europe published in 2006 as a result of the CRAYNET project, and were further updated from more recently published reports, grey literature, and especially thanks to contributions and feedback of over 70 specialists from 32 countries. Separate maps are available for all indigenous crayfish species in Europe as well as for three most widespread non-indigenous crayfish species. Additionally, two maps give locations of known findings of crayfish species introduced to Europe after 1980. These newly established alien species have so far restricted distributions; however, the frequency of recent reports suggests that findings of such species resulting from releases of aquarium pets will further increase. RÉSUMÉ Répartition à l'échelle continentale des espèces d'écrevisses en Europe : mises à jour et cartes Mots-clés :distribution des écrevisses, espèces indigènes, espèces envahissantes, Les études astacologiques récemment publiées ont sensiblement amélioré les données disponibles sur la distribution des écrevisses dans les différentes régions européennes. Dans le même temps, la propagation des espèces envahissantes a été enregistrée, des espèces non indigènes supplémentaires se sont établies dans différents pays, et des pertes de populations d'espèces indigènes en raison de la peste des écrevisses et d'autres facteurs négatifs ont été observées. Nous synthétisons les progrès récents dans la connaissance, et fournissons des cartes en couleur mises à jour de la distribution de toutes les espèces d'écre-visses présentes en Europe. Ces cartes sont à l'origine basées sur les données de l'Atlas des écrevisses en Europe publié en 2006 à la suite du projet CRAYNET, et ont ensuite été mises à jour à partir des études publiées plus récemment, de la

“…This 'centrality' makes P. antennarius a more imperiled taxon if we also consider the introduction and spreading of both alien invertebrates and fish species as potential competitors and/or predators This may be the case for very stressed areas such as in central Italy where diverse invasive crayfish (Chiesa et al, 2006;Nonnis et al, 2009;Scalici et al, 2010Scalici et al, , 2009bScalici et al, , 2009cDörr and Scalici, 2013;Bissattini et al, accepted) and their unsafe parasites (Dörr et al, 2011(Dörr et al, , 2012a(Dörr et al, , 2012bChiesa et al, 2015) were recorded and described. Scientists are often expected to indicate the most important species which disturbance may originate the main detrimental effect on both occurrence and abundance of other taxa in a community (Jones et al, 1994).…”

-We evaluated the importance of the freshwater grass shrimp Palaemonetes antennarius as trophic source for the lacustrine fish of the Lake Bracciano (Central Italy) analyzing 6120 stomach contents of 10 species. Shrimp was recorded for all size classes of the investigated species with a variation in frequency and abundance depending on seasons. P. antennarius was occasionally preyed by cyprinids, and systematically by small individuals of carnivorous fish. Our findings acquire more importance if we take the shrimps ecological niche into account, as it is potentially acting as detritivorous/generalist and predator of benthic invertebrates as well. This feeding behavior makes P. antennarius an important network ring, being a taxon that ought to receive the same attention recommended for other freshwater decapods as proposed for Austropotamobius pallipes and Potamon fluviatile.

“…In Italy several non-native crayfish have been recorded (Souty-Grosset et al, 2006;Capurro et al, 2007;Gherardi et al, 2008b): (a) three American species, the red-swamp crayfish Procambarus clarkii (Girard, 1852), the spiny-cheek crayfish Orconectes limosus (Rafinesque, 1817), and the signal crayfish Pacifastacus leniusculus (Dana, 1852); (b) two Australian species, the yabby Cherax destructor (Clark, 1936), and the redclaw C. quadricarinatus (von Martens, 1868); (c) one eastern European species, the narrow-clawed crayfish Astacus leptodactylus (Eschscholtz, 1823). C. quadricarinatus was only observed in rearing systems , whilst C. destructor was recently recorded in abandoned outdoor ponds within the protected area "Laghi di Ninfa" (Latina, Latium) (Scalici et al, 2009a Chiesa et al, 2006), and C. destructor (Scalici et al, 2009a). On the whole, NICs show a wide distribution due to their ability to adapt to a wide range of habitat and food sources, especially P. clarkii (Gherardi, 2006;Scalici et al, 2009b).…”

Introductions of non-indigenous crayfish have received great attention from biologists and policy makers during the last decade. Purposes of this study are to update the knowledge about the crayfish distribution in Latium (central Italy), and to show how interactions between indigenous and non-indigenous species can affect their distribution. The main findings of this study were (1) the great decrease of the Austropotamobius pallipes populations and (2) the alarming spread of the four non-indigenous species red swamp crayfish Procambarus clarkii (the main widespread crayfish), spiny-cheek crayfish Orconectes limosus, narrow-clawed crayfish Astacus leptodactylus, and yabby Cherax destructor. We never observed indigenous and non-indigenous crayfish living in syntopy, although we noted that white-clawed crayfish had become extinct at sites where non-indigenous crayfish species exist now. Other type of problems (i.e. illegal harvesting and over-abstraction of water for human use) can also reduce the distribution and abundance of the indigenous crayfish stocks. The distribution of Italian crayfish populations has not been studied sufficiently and more studies are required nationwide to assess the conservation status of A. pallipes and the occurrence of non-indigenous species. A national database of crayfish records ought to be constructed and regularly updated.
