The Sicilian wolf remained isolated in Sicily from the end of Pleistocene until its extermination 1930s-1960s. Given long-term isolation on island and distinctive morphology, genetic origin remains debated. We sequenced four nuclear genomes five mitogenomes seven existing museum specimens to investigate ancestry, relationships with extant extinct wolves dogs, diversity. Our results show that is most closely related Italian but carries ancestry a lineage European Eneolithic Bronze Age dogs....
Two cobra species are found in the forest block of southern Nigeria (West Africa). However, whereas one species, spitting (Naja nigricollis), is often strongly altered habitats (including suburban areas), other, black melanoleuca), a typical that currently subject to rapid decrease population abundance because intensive alteration and landscape modification this part Africa. We studied whether body sizes, diets, feeding strategies these two changed relation habitat type, ecological success...
Aspects of comparative ecology were studied in the spitting cobra, Naja nigricollis, and black forest melanoleuca, from southeastern Nigeria. Both species common widely distributed study region. melanoleuca inhabited mainly primary secondary patches, but also plantations suburbia. The two differed significantly terms habitat types frequented. A logistic regression model showed that presence N. was influenced by a unique macrohabitat category (primary swamp-forest), whereas or absence...
Abstract Food habits of the royal python (Python regius) were studied in some localities southeastern Nigeria by means both faeces analysis and forced regurgitation living individuals. Female pythons significantly longer than males. Both sexes preyed exclusively upon birds mammals, but there significant intersexual differences terms dietary, composition. Males more frequently (70.2% total number prey items) whereas females mammals (66.7% items). There was an apparent ontogenetic change diet...
Abstract Food habits of the green lizard (Lacerta bilineata) were studied in some Mediterranean sites vicinities Rome (Latium, central Italy), by means both stomach dissection individuals found already dead field and faeces analysis living individuals. The taxonomic diet composition lizards was accurately described methods, thus demonstrating reliability faecal pellet as an non‐cruel method to study diets. However, using technique, it is difficult measure exact food intake rate (items / unit...
La distribution et l’écologie des Chéloniens dulçaquicoles terrestres ont été étudiées dans l’est du delta Niger au Nigéria. Cinquante deux zones d’étude, distribuées le long bassins hydrographiques principales rivières les principaux types d’environnement présents la région, soigneusement prospectées durant plus de ans. Sept espèces trouvées ; quatre d’entre elles (Pelomedusa subrufa olivacea, Pelusios c. castaneus, Kinixys belliana nogueyi, erosa ) étaient pour première fois signalées...
As species become rare and approach extinction, purported sightings can be controversial, especially when scarce management resources are at stake. We consider the probability that each individual sighting of a series is valid. Obtaining these probabilities requires strict framework to ensure they as accurately representative possible. used process, which has proven provide accurate estimates from group experts, obtain for validation 32 Barbary lion. scenario where experts simply asked...
Several aspects of the ecology Jameson’s green mamba Dendroaspis jamesoni (Traill, 1843), a large-sized arboreal elapid snake, are studied in southern Nigeria. This species is common and widespread region studied. On basis analysis both habitats capture various specimens results logistical regression model, it seems that this inhabits wide variety (including secondary forest patches plantation-forest mosaic), its local distribution not influenced by presence any macrohabitat parameter. Green...
Present knowledge on mammals of small Italian islands consists mainly episodic records. In this paper we collect all available information about the distribution wild 47 islands. A total 37-38 species was found, including: 1 Erinaceomorpha, 4 Soricomorpha, 16-17 Chiroptera, 3 Lagomorpha, 7 Rodentia, 2 Carni- vora and Artiodactyla. The subspecific level has been identified whenever possible. mammal fauna Isle Elba (Tuscan Archipelago) is richest, with 24 species, while most common are Rattus...
The food habits of a freshwater pelomedusid turtle (Pelomedusa subrufa) were studied by fecal analysis and stomach flushing in 2 study areas Nigeria. Males females predominantly carnivorous; they fed mainly on fish, tadpoles, aquatic invertebrates but also terrestrial vertebrates. Sexes overlapped highly dietary during both wet dry season. Body size clearly affected diet composition turtles did so only the season (with smaller individuals feeding primarily small vertebrates, larger...
Historically, many local grey wolf (Canis lupus) populations have undergone substantial reductions in size or become extinct. Among these, the population once living Sicily, largest island Mediterranean Sea, was completely eradicated by human activity early decades of 20th century. To gain a better understanding genetic identity Sicilian wolf, we used techniques for study ancient DNA to analyze mitochondrial (mt) variability six specimens stored Italian museums. We were able amplify...
Abstract The current distribution of Lepus corsicanus (recently considered to be a distinct species from L. europaeus ) in peninsular Italy and Sicily is presented this paper. Our data suggest that declining markedly mainland Italy, perhaps also Sicily, it should categorised as Endangered on the IUCN Red List. Conservation recommendations for are presented.
The common genet (Genetta genetta) is a small carnivoran that was probably introduced from Maghreb into south‐western Europe. We reassessed its easternmost European distribution 110—mostly new—data collected in south‐eastern France and Italy, tested for potential habitat selection, to finally re‐evaluate the role of Rhône as geographic barrier against eastward migrations. species more frequent river valleys, wetlands low‐mountainous areas (south‐eastern France), but also occurred...
The food habits of the snake Psammophis phillipsi were studied in rain-forest region southeastern Nigeria, where this is most common species area. A total 120 prey items recorded from 327 specimens (73 juveniles; 55 gravid females); many females contained prey. Lizards (mainly Agama agama and Mabuya skinks) type for adult snakes, both nongravid, subadults as well; small mammals second all categories. Insects snakes (including conspecifics) occasionally consumed. Diet composition did not...
The small mammal fauna of a forest area in southern Nigeria is studied order to understand the general patterns regulating community composition. A set different methods trapping was used evaluate composition species at level both ground-dwelling and arboreal guilds. For Insectivora, six shrew were trapped, but only two (Crocidura nigeriae C. poensis) appeared abundant widespread various habitat types. No found. rodents, 17 captured, which arranged by Principal Component Analysis into four...
