Water mites of small boreal forest lakes (Central Finland)
1999
The water mite fauna of 10 small forest lakes in close proximity to each other was studied in 1979–1985. In total approximately 62 species of water mites belonging to 22 genera were detected in the lakes. The most diverse genera were Piona (14 species), Arrenurus (11), Unionicola (4) and Limnesia (4). Widely spread and abundant species were Piona variabilis and Limnesia maculata. Locally abundant were Unionicola crassipes, U. minor, Piona carnea and P. paucipora. Zoogeographically interesting though accidental species were Arrenurus werestschagini, Limnesia polonica, Momonia karelica, Piona gyrophora and Unionicola parvipora. Considerable spatial and seasonal differences were observed in th…

2018
New distributional data concerning 134 species of terrestrial true-bugs in the Bydgoszcz city (N Poland) are presented, including 10 species recorded for the first time from Wiel-kopolsko-Kujawska Lowland, i.e., Aellopus atratus, Deraeocoris flavilinea, Dicyphus annulatus, Drymus ryeii, Emblethis denticollis, E. duplicatus, Ischnocoris angustulus, Pionosomus opacellus, Scolopostethus pilosus, Taphropeltus hamulatus. Taking into account previous literature data, the list of Heteroptera species recorded in the Bydgoszcz city comprises 166 species.
Helminth communities of two lizard populations (Lacertidae) from Canary Islands (Spain): Host diet-parasite relationships
2005
Abstract A parasitological survey has been carried out to determine the relationships between host diet and parasite fauna. Diet, and infracommunities and component communities of two subspecies of lacertid lizards, Gallotia galloti galloti (Oudart, 1839) and G. g. palmae (Boettger et Müller, 1914) from Tenerife and La Palma islands (Canary Islands, Spain), have been analysed. High values of parasite infection parameters were found in both subspecies, which were only infected by nematodes of the family Pharyngodonidae. Plant matter was mainly consumed by both lizard subspecies and relevant amounts of mineral matter were also found in both hosts. Diet of these lacertid lizards was correlate…

The conservation status of West African vultures: an updated review and a strategy for conservation
2018
The vulture populations in West Africa are undergoing dramatic decline over the last 30 years. Their particular ecology and sociality makes them vulnerable to various risks, including environmental changes, poisoning and bioaccumulation of toxic substances from agricultural products, pesticides, and veterinary drugs used in cattle livestock. In addition, these birds are subject to direct persecution for the trade of products used in traditional medicine. This manuscript analyzes the conservation status of eight vulture species in West Africa and the threats affecting their survival. In order to assess the conservation status of vultures in West Africa, this paper analyzes all the available …
An overview of the Ephydridae (Diptera) of Saudi Arabia
2019
Despite the species richness of Ephydridae world-wide (2000 species) and its prominent environmental roles as a minor pest and as a food for wildlife, only 13 species have been recorded from Saudi Arabia. Between 2012 and 2016, a biodiversity study of Diptera was conducted at Jazan, Asir, and Najran in south-western Saudi Arabia, at 22 sites, was performed mainly using Malaise traps and sweep nets. In this study, 43 known species of Ephydridae were identified, 37 of them for the first time from southwestern Saudi Arabia and 16 from Arabian Peninsula. This brings the total number of Ephydridae species in Saudi Arabia to 49 (including previous records). There were a further four species, whic…
Water striders (Heteroptera: Gerromorpha: Gerridae) of Romania with an update on the distribution of Gerris gibbifer and G. maculatus in southeastern…
2018
The Romanian fauna comprises two species of Aquarius Schellenberg, 1800, eight species of Gerris Fabricius, 1794 and one species of Limnoporus Stål, 1868, and we hereby update the distribution and provide insights on the phenology and ecology of all eleven species in this country. We furthermore update the distribution of the two closely related species Gerris gibbifer Schummel, 1832 and G. maculatus Tamanini, 1946 in southeastern Europe. Gerris maculatus is recorded for the first time from Hungary, Montenegro and Slovenia, and the first detailed localities from Romania and Serbia are given. All bibliographic records of G. gibbifer from Romania, Macedonia and Serbia are based on misidentifi…
THE GARGANO TERRE ROSSE INSULAR FAUNAS: AN OVERVIEW
2010
After forty years from its discovery, the history of the field surveys and of the researches on the fossiliferous deposits on Gargano is briefly reported. The Gargano fauna belongs to the Abruzzo-Apulian Palaeobioprovince (including also Scontrone and Palena, Abruzzo). The fossil assemblage comprehends all the classes of terrestrial vertebrates: Reptilia, Amphibia, Aves and Mammalia. The faunal composition is unbalanced and presents the features of a typical insular endemic fauna. The bulk of the assemblage is composed of small mammals and birds. Based on literature, we report the most characteristic features, phylogenetic relationships, and evolutionary remarks on a list of mammals, focusi…
Indagini archeozoologiche della Palermo antica: la Gancia, Palazzo Bonagia e Via Imera.
L’analisi archeozoologica della Palermo medioevale qui presentata si inserisce nell’ambito degli studi di antropologia e di archeologia medievale che da oltre un decennio stanno interessando il centro storico della città. Il presente studio mira alla ricostruzione dell’ecologia umana durante il periodo di islamizzazione della Sicilia e di Palermo, attraverso l’analisi dei resti faunistici di tre siti inediti del centro storico di Palermo, la Gancia, Palazzo Bonagia e Via Imera, in un periodo compreso tra la fine del IX e il X sec. d.C., e l’analisi comparativa di resti provenienti da centri rurali siciliani, alcuni di questi databili fino al XV secolo. L’analisi ha messo in evidenza alcuni …
