We studied the factors affecting the distribution of an endemic shrewSorex samniticus Altobello, 1926 in the Province of Siena, central Italy. Distribution data were obtained by examining pellets from 31 barn owlTyto alba sites (roosts) over a period spanning from 1974 to 2005. We constructed a model using logistic regression analysis on presence/absence data. Results show that an increase in forest dominated byQuercus cerris andCastanea sativa led to the local extinction of this species… Expand

Is the common shrew (Sorex araneus) really a common forest species?
TLDR
A very low abundance of the common shrew was found in fir-beech forests of the Kremnické vrchy Mts. Expand
Distribution and coexistence of shrews in patchy landscapes: A field test of multiple hypotheses
TLDR
The data supports the hypotheses that patterns of habitat selection and the dynamics of seasonal abundance reduce competitive pressure, thus allowing coexistence of shrews in relatively species-rich assemblages, for such small amounts of habitat. Expand
Forty years of dietary studies on barn owl ( Tyto alba ) reveal long term trends in diversity metrics of small mammal prey
TLDR
The diet composition of the barn owl in Italy was studied using a meta-analysis of 47 articles, with a significantly negative correlation between year and the frequency of consumption of Sorex spp. Expand
Spatial analysis of species richness of shrews (Soricomorpha: Soricidae) in North America north of Mexico
We used geographic ranges of North American shrews and environmental data to better understand spatial distribution of species richness in the Soricidae. Richness was examined as a function ofExpand
Reviewing an eco-biogeographic question at regional scale: the unexpected absence of a ubiquitous mammal species (Microtus savii, Rodentia) in coastal Southern Tuscany (central Italy)
We reviewed the historical and recent data about the unexpected absence of a generalist ubiquitous mammal (Savi’s pine vole Microtus savii, Rodentia) from a large sub-regional coastal land reclaimedExpand
Altitudinal variation of community metrics in Italian small mammal assemblages as revealed by Barn Owl (Tyto alba) pellets
TLDR
It is thought that the decrease in number of species of Rodentia with altitude may depend on the higher rate of agricultural land existing at lower elevations in Italy, with the Soricinae being more linked to temperate bioclimates than the Mediterranean-bioclimate-linked Crocidurinae. Expand
Small mammal assemblages in land-reclaimed areas: do historical soil use changes and recent anthropisation affect their dominance structure?
TLDR
It is hypothesised that recent anthropisation and historical land reclamation could strongly affect the structure of the small mammal assemblage, dominated by a single taxonomic guild (Muridae), therefore similar to neighbouring insular assemblages (Tuscan Archipelago). Expand
CORINE-based landscape indices weakly correlate with plant species richness in a northern European landscape transect
We present the results of one of the few available tests of how CORINE (CLC2000) is likely to perform as a basis for the calculation of landscape indices, for environmental monitoring over largeExpand
Check-list of Vertebrates in the "t enuta dei massimi" nature reserve (Rome, central Italy) with some remarks on local conservation priorities
We reported a complete check-list of Vertebrates for the "Tenuta dei Massimi" nature reserve, a protected area well repre- senting a remnant agro-forest heterogeneous mosaic landscape of theExpand
Long term variations in small mammal composition of a snake diet do not mirror climate change trends
TLDR
A significantly positive relationship between small mammal abundance in the field and their relative frequency of occurrence in the viper's diet is found, thus demonstrating that vipers really sampled the small mammal species in relation to their local availability. Expand

Abstract A high number of preys (7,147 specimens) from barn owl pellets were collected in 15 sites of Monte Rufeno Natural Reserve. The 97.42% were small mammals, belonging to at least 6 species ofExpand

TLDR
Standardized quantitative sampling techniques, like Owl pellets analysis, can enable not only to enhance faunistic knowledges, but also to estimate the actual absence probability of a given taxon "m", lacking from the diet of an individual raptor. Expand
Overlap of temporal niches among four sympatric species of shrews
TLDR
The study of activity patterns in a shrew community of two semiaquatic species and two terrestrial species confirmed the idea that small shrew species with higher metabolic rate have more frequent and more equally distributed activity bouts than large species. Expand

: Ecological networks consist of core areas connected by corridors and shielded by buffer zones. It is now largely accepted that extensive networks need to be established at different scales toExpand
Mammal diversity and taxonomy in Italy: implications for conservation
TLDR
The aim of the present work is to outline the need to incorporate phylogenetic and biogeographic data in the assessment of conservation priorities among mammals in Italy, in order to maximise the national contribution to biodiversity conservation in Europe. Expand
Diets and coexistence in Neomys and Sorex shrews in Białowieża forest, eastern Poland
TLDR
The results support the prediction that microhabitat selection among these species indicates differentiation in foraging mode, and suggest that the most important promoter of resource partitioning was body size, indicating different foraging modes. Expand
Designing a Coherent Ecological Network for Large Mammals in Northwestern Europe
In densely populated northwestern Europe, native large mammals are confronted with a very fragmented landscape, and most of the areas they inhabit are island-like reserves threatened with totalExpand
Diets of the shrews Sorex araneus L. and Sorex minutus L. in Wytham grassland.
Animals were collected in an area known as Rough Common where thin soil covers the limestone cap of Wytham Hill and Brachypodium pinnatum (L.) is the dominant plant species. The area is divided by aExpand
A taxonomical re-evaluation of the Valais chromosome race of the common shrewSorex araneus (Insectivora: Soricidae)
TLDR
In a phylogeny based on complete mitochondrial DNA cytochromeb gene sequences, the Valais race clearly appears as the sister taxon to all other races of S. araneus and the name Sorex antinorii Bonaparte, 1840 is applied. Expand
Predation on Small Mammals by Tawny Owl and Comparison with Barn Owl in the Farma Valley (Central Italy)
TLDR
It is brought to light that the tawny owl's trophic niche, generally, is quite different from the born owl's, however two niches may in some way overlap, when the barn owl is roosting near wooded areas, thereby further substantiating the euryphagy of the barn Owl. Expand
