Physical description:
“The Italian wolf population represents an interesting case study for its uniqueness worldwide. At the beginning of the 20th century Altobello (1921) described the Italian wolf as a distinct subspecies, C.l.italicus, based on its peculiar morphological traits: relatively small average size (110–148cm body length, plus the tail), dark bands along the back and fore limbs, black tail tip, and distinct craniometrical features, recently confirmed by Nowak and Federoff (2002).”

Range:
Original rangeWidespread on the Italian peninsula, including Sicily (Until mid-1800’s).

Current rangeItaly. Throughout the Italian Peninsula

“The Italian wolf (Canis lupus italicus) population has remained isolated South of the Alps for the last few thousand years. After a strong decline, the species has recolonized the Apennines and the Western Alps, while it is currently struggling to colonize the Eastern Alps. Recently, the species was detected in a lowland park connecting the Northern Apennines to the Central Alps. If the park was able to sustain a net wolf dispersal flow, this could significantly boost the connection with the Eastern Alps and the Dinaric-Balkan population.”

Prey
Primary in Northern Italy roe deer (Capreolus capreolus), wild boar (Sus scrofa)

Alternativefallow deer (Dama dama), chamois (Rupicapra rupicapra), red deer (Cervus elaphus), mouflon (Ovis aries musimon), Italian hare (Lepus corsicanus) European hares (Lepus europaeus), livestock (goats (Capra hircus), sheep (Ovis aries), cattle calves (bos tauras)) OTHER food; birds,  invertebrates, fruit, berries, grasses, herbs, garbage.

“Surprisingly, we did not find significant changes of the food categories from grazing to non-grazing seasons, with the exception of fruits that were more eaten in the grazing one. As for wild ungulates, wolves used wild boar in winter and roe deer in summer; in summer, roe deer are more vulnerable because of the presence of young, and in winter,several wild boars are injured and not retrieved by hunters during drive hunts and consequently are easily found and caught by wolves.Moreover snow depth makes wild boars more vulnerable to predation (Okarma, 1995).”

“The most recent research (Procaccio 2015) confirmed the high selectivity which characterizes the wolf diet, with an almost exclusive consumption of wild ungulates (83.8%, represented by wild boar 25.2 %, roe deer 65.9%, fallow deer 3.4%) and very low value of diet breadth (B =0.17). The most important result of this last study was the significant increase in the use of roe deer, which probably depends on the recent expansion of wolves towards lower elevation hilly zones.”

“The PNALM, a critical stronghold for wolves in Italy when they were most exposed to extinction risk (Zimen and Boitani,1975), adopted since the 1970s farsighted conservation measures aimed to enhance the ecological conditions for wolves;these included the strict protection of the Apennine chamois and the reintroduction of the previously extirpated roe and red deer (Tassi, 1976). This, in addition to the hunter-assisted releases and successive expansion of wild boar throughout the region, facilitated the re-establishment of the rich and diversified wild prey community to which wolves are currently exposed. Accordingly, we confirmed that roe deer, wild boar and red deer are all actively predated by wolves in the PNALM.Nevertheless, beyond our expectations, we also revealed that livestock, and in particular carcasses of cattle and horses, largely affected wolves’ feeding behavior and predominated their diet in terms of biomass.”

“The species has re-colonized the northern Apennines (since the late 1980’s) and reached the western Alps (from the early 1990’s) through the ecological corridor of Liguria (a NW region of Italy) (Lucchini et al. 2002; Valiere et al. 2003; Fabbri et al. 2007). A moderate bottleneck occurred during the re-colonization process, and gene flow between the Apennines was moderated (1.25-2.50 wolves per generation (Fabbri et al. 2007). Bottleneck simulations showed that a total of 8-16 effective founders explained the genetic diversity observed in the Alps (Fabbri et al. 2007). Nowadays, the expansion of the wolf range into continuing toward the eastern Alps and Europe (Switzerland, Austria and France).”

ABSTRACT

The Apennine wolf (Canis lupus italicus, Altobello, 1921) is currently experiencing a period of great population change. Any information that helps to understand this transformation will be valuable for managing it. Here we provide, for the first time, quantitative data (habitat suitability, segregation, seasonal activity, daily time budget, social structure and sex-ratio) on the population of Italian wolf from the Cilento, Vallo di Diano and Alburni National Park, the largest protected area in Italy, that houses a rising population. Using transects to locate signs and traces, we have identified 224 presence points, useful for elaborating the ecological suitability map for the wolf, in and around the Park. The suitable area expands up to 1042.65 km2, with elevation being the strongest predictive variable affecting the species. The model predicts two main suitable patches (Alburni Mountains and Cervati/Motola Mountains), and at least seven remote areas, differently linked to each other by ecological corridors. Camera-trapping information was collected in the two suitable patches (Alburni and Cervati/Motola) for the wolf and revealed some characteristics of this population. The highest number of wolves was recorded in May and December, and during the night, depending on the reproductive behavior and dynamic of dispersion. Single individuals and couples (at least 3 recorded) are observed more frequently than groups (maximum of 3 groups that varied from three to eight individuals). The sex-ratio in the population, inferred by camera-trapping, showed a balanced population, with males found to be group leader in 91% of the cases. Furthermore, genetic analysis revealed that the males were in charge of marking the territory in 86% of cases. Our data increases the knowledge of the wolf population from Cilento, which seemed to have stopped at the 1990s, until now. Our contribution could be helpful in defining a wolf management strategy in the National Park, as well as in the other regions of the Apennine mountains and Alps, where the wolf is expanding, aiming also at coexistence with local human communities.
