Amendment of the type locality of the endemic Sicilian pond turtle Emys trinacris Fritz et al. 2005, with some notes on the highest altitude reached …
2016
The type locality of the Sicilian pond turtle Emys trinacris is here amended, and its correct name and geographical coordinates are provided. The locus typicus of the species lies at 1007 m a.s.l., i.e. nearly 400 m below what previously thought. The updated altitudinal distribution range of the species, based on verified published localities only, is between 0 and 1036 m a.s.l.
Testing the enemy release hypothesis: abundance and distribution patterns of helminth communities in grey mullets (Teleostei: Mugilidae) reveal the s…
2017
International audience; The abundance and aggregation patterns of helminth communities of two grey mullet hosts, Liza haematocheilus and Mugil cephalus, were studied across 14 localities in Atlantic and Pacific marine areas. The analysis matched parasite communities of (i) L. haematocheilus across its native and introduced populations (Sea of Japan and Sea of Azov, respectively) and (ii) the introduced population of L. haematocheilus with native populations of M. cephalus (Mediterranean, Azov-Black and Japan Seas). The total mean abundance (TMA), as a feature of the infection level in helminth communities, and slope b of the Taylor’s power law, as a measure of parasite aggregation at the in…
Gastrointestinal parasites of two populations of Arctic foxes (Vulpes lagopus) from north-east Greenland
2017
Parasitological examination of 275 faecal samples from Arctic foxes (Vulpes lagopus) collected at Zackenberg Valley and Karupelv Valley in north-east Greenland from 2006 to 2008 was conducted using sieving and microscopy. Overall, 125 (45.5%) samples contained parasite eggs of Taenia crassiceps, Taenia serialis, Toxascaris leonina, Eucoleus boehmi, Physalopteridae and Ancylostomatidae, and Strongyloides-like larvae. As long-term ecological studies are conducted at both sampling locations, the present findings constitute a baseline data set for further parasitological monitoring.
Living in a harsh habitat: epidemiology of the whale louse, Syncyamus aequus (Cyamidae), infecting striped dolphins in the Western Mediterranean
2017
Whale lice (Cyamidae) are ectoparasitic amphipods exclusive to cetaceans. Data on their epidemiology usually come from species infecting baleen whales, which are large, slow-moving hosts. In this study, we provide data on infection parameters, population structure and microhabitat selection in a whale louse exclusive to delphinids, Syncyamus aequus, with the aim of comparing them with those from cyamid species from large whales. A total of 176 striped dolphins Stenella coeruleoalba stranded along the Mediterranean coast of Spain during 1980–2016 were examined. The prevalence of S. aequus was 27.3% (95% CI: 20.9–34.3), and populations were sparse, with a mean number of whale lice per infecte…
Botryosphaeriaceae species associated with diseased loquat trees in Italy and description of Diplodia rosacearum sp. nov
2016
[EN] Loquat (Eriobotrya japonica) is a fruit tree cultivated in several countries in the Mediterranean region. A survey of a loquat orchard in Sicily ( Italy) revealed the presence of plants showing dieback symptoms and cankers with wedge-shaped necrotic sectors. Fungi from the genera Diplodia and Neofusicoccum were isolated from symptomatic plants. On the basis of morphological characters and DNA sequence data four species were identified, Neofusicoccum parvum, N. vitifusiforme, Diplodia seriata and a novel Diplodia species, which is here described as D. rosacearum sp. nov. Inoculation trials of loquat plants cv Sanfilipparo showed that N. parvum, D. seriata and D. rosacearum were pathogen…
Buchwaldoboletus lignicola (Boletaceae), a rare basidiomycete from Europe
2017
AbstractBuchwaldoboletus lignicola is a rare basidiomycete with fragmented distribution in Europe. The taxonomy, ecology and distribution of this species is reported. The new locality from central Sicily widens the area of distribution of B. lignicola in Europe.
First record of Capnobotrys dingleyae (Metacapnodiaceae) on Taxus baccata for southern Europe
2017
Field investigations carried out in a mixed forest of Fagus sylvatica and Taxus baccata in the Nebrodi Natural Park (Sicily, southern Italy) allowed us to identify a very rare lignicolous ascomycete Capnobotrys dingleyae, a new species for southern Europe.
Epiphytic communities of open habitats in the western Tian-Shan Mts (Middle Asia: Kyrgyzstan)
2016
The paper presents the results of bryosociological research conducted on the epiphytic vegetation in the western Tian-Shan Mountains in 2013. The surveys on epiphytic bryophyte and lichen communities were done on 115 sites with different quantity of trees (solitary, in alleys or wood plots along river valleys) distributed in several mountain ranges within study area. In total 21 epiphytic moss species were found during research which composes characteristic species combinations making apparent difference between associations. As a result of field research and numerical analyses, three separate groups of samples corresponding to seven associations and one community within three alliances: Ul…
Updated checklist of macromycetes of Tunisia
2020
A preliminary checklist of macromycetes has been previously published with reference to six governorates located in northern Tunisia. This paper provides an updated version of the inventory of macromycetes in Tunisia, which includes 268 species, of which seven are worldwide recognized as rare. The investigation was carried out from September 2015 to December 2018 in 13 governorates of the Tunisian territory. This updated checklist reports 145 new national species records (139 basidiomycetes and six ascomycetes) belonging to 57 genera and 13 families. Data related to distribution, ecology and preferential hosts of each recorded taxon are also provided.
Genetic diversity of Rhizoctonia solani associated with potato tubers in France.
2011
Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; The soilborne fungus Rhizoctonia solani is a pathogen of many plants and causes severe damage in crops around the world. Strains of R. solani from the anastomosis group (AG) 3 attack potatoes, leading to great yield losses and to the downgrading of production. The study of the genetic diversity of the strains of R. solani in France allows the structure of the populations to be determined and adapted control strategies against this pathogen to be established. …
