Small northern mammals undergo regular developmental and seasonal moults. However, the moulting patterns of many small mammals are not well known. Development and subsequent moulting of the pelage was documented in adult red-backed volesClethrionomys gapperi Vigors, 1830 and their offspring in relation to age, weight, and sex. Red-backed voles exhibited 4 developmental pelages (nestling, juveniles, subadult, and adult) through diffuse, rapid hair growth. Rapid growth was associated with early moulting at the nestling, juveniles and adult stages. However, a trade-off between moulting and growth existed at the subadult stage such that delayed moulting was associated with rapid growth. Adult voles completed a unique moult progression with highly variable timing. Male and femaleC. gapperi showed no differences in pattern or locations of moulting. Variation in the number and timing of moults in small mammals may reflect differences in life-history strategies and highlights the need for a consistent mammalian pelages and moults nomenclature.

The European pine marten (Martes martes) is commonly classified as an opportunistic predator. If this is the case, the species ought to show seasonal differences in the small mammal composition of its scats – the types of prey taken depending on their abundanc. In addition, it ought to consume the food that requires lower energy cost for their acquisition in each season. The feeding strategy of the European pine marten was studied in northwestern Spain by analyzing 209 scats collected between July 2004 and June 2005, and by seasonally trapping small mammals to obtain information on their abundance. The study area (5,722 ha) was located in a mountainous region (1,707–880 m a.s.l.) and covered with brushwood and deciduous forest (oak, birch, holly and pine). Molecular analysis of scats (PCR-RFLP) was performed to rule out the presence of the stone marten (Martes foina L.). The frequency of occurrence and biomass of the small mammals (the main prey species) preyed upon each season were compared. The pine marten consumed significantly more small mammals in the seasons in which their abundance was the lowest (winter and spring). In the autumn, when the highest number of small mammals was detected, the pine marten did not increase its predation of them. These results indicate that the European pine marten is not an opportunistic predator. Rather, the feeding strategy adopted by the species seems to be intermediate between that of an opportunist and specialist predator.

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. Results were confirmed through the examination of one box, with 3044 prey items deposited in layers, that documents the expansion of the species in that area following increased logging ofQuercus cerris andCastanea sativa forests. Cessation of logging has again led to the absence of the species from the area. We discuss these results from the perspective of ecological network planning, showing that utilisation of non-detailed maps, such as Corine Land Cover, that do not distinguish between the various kind of broadleaved forests is inadequate to describe the finer grade of habitat selection of this small mammal.

The presence of antibodies against Chlamydophila (Chlamydia) psittaci in small mammals (Insectivora, Rodentia) in the region of East Slovakia are presented. The hosts were caught in several areas of Slovakia in habitats with different levels of anthropogenic disturbance. Research was carried out during 2000-2002. The authors examined 1,947 sera coming from 4 insectivore and 10 rodent species. Each serum was examined by micromethod of complement binding reactions using antigen Chlamydophila (Chlamydia) psittaci. Chlamydial infections were found in 251 individuals (prevalence 12.9%) of 8 mammal species. The antichlamydial antibodies were proved at levels ranging from 1:32-1:1024. The highest prevalence of antibodies was detected in the most abundant rodent species Apodemus microps (14.8%), Apodemus agrarius (13.9%), Apodemus flavicolis (12.4%), Microtus arvalis (12%), and Clethrionomys glareolus (10.9%). Positive hosts were registered in all studied localities. Testing of prevalence values in the individual research years confirmed significant changes. Our results showed that small mammals probably play an important role in the circulation of chlamydiae in nature.

Fluorescent paint powders have frequently been used to determine the spatial activity patterns and microhabitat use of small mammals. The time of day that powdered animals were released differs among studies and data used in many studies were collected on the trails of powdered animals released in the morning outside the normal period of activity of many species of small mammals. We tested for differences in the characteristics of fluorescent powder trails of white-footed mice Peromyscus leucopus (Rafmesque, 1818) released using three protocols: night capture-night release, morning capture-morning release, and morning capture-delayed night-release. The night release and morning release protocols were established to replicate the extremes found in the literature. We added the third protocol to evaluate how capturing mice in the morning, holding them in captivity, and releasing them at night affected their use of microhabitat. There were no significant differences in the use of microhabitat between the night release and delayed night-release treatments. However, a significantly greater proportion of the trails of mice released in the morning were in areas of thick cover and under logs than the trails of mice released at night. Because mice released during the day used microhabitat differently than mice released at night, we caution against the interpretation of data on use of habitat collected using the fluorescent powder trails of animals released outside their normal period of activity.

We present a new method of collective marking (rhodamine B) of small mammals that can be used under natural conditions. We examine the acceptance of marked baits, detection and persistence of the signal on the different kinds of hairs of two small species of rodents. Rhodamine B was ingested by captive animals and their hairs were dyed a fluorescent red coloration and observed over more than 150 days. Preliminary results obtained under field conditions tend to demonstrate that winter and summer movements could be detected by this technique. This new collective marking technique may be of great interest to study population turnover and movements of small mammals between habitat patches; it may represent an important method of assessing connectivity and permeability of landscapes by small mammals.

Despite its conservation potential, little is known of whether land taken out of arable production as set-aside benefits wildlife, nor what features enhance its value as a habitat. We studied the presence of small mammals on one-year set-aside through a summer harvest period (278 captures in 3000 trap nights). Trapping success was low on all set-aside (0.6%), but was higher in adjoining hedgerow (30%) and cereal crops (13%). Wood mice Apodemus sylvaticus (Linnaeus, 1758) were the most commonly caught species, and the only species to occur on set-aside. There were no significant differences in trap success between set-aside configured in blocks and strips, nor between sown and naturally regenerated set-aside. Captures on set-aside increased after harvest, when the crop no longer provided cover. Our data demonstrate that set-aside is not necessarily a suitable habitat for small mammals.

Small mammals were trapped in 12 habitats in 2002 and 2003. In all, 56 individuals of 9 species were caught in 2002, and 751 individuals of 11 species – in 2003. Insectivora communities did not differ statistically significantly in the two consecutive years (trappability index = number of individuals caught/trap-nights number Wo2002 = 1.26%; Wo2003= 0.72%; p<0.01), whereas the Rodentia community differed significantly (Wo2002 = 3.15; Wo2003‘03 = 30.88 p<0.03). In both years, the most numerous among the animals trapped were A. flavicollis and C. glareolus among rodents and S. araneus among insectivores, dominating in almost all habitats. The least diverse group was that of beech forest and alder wood ecotone (Simpson’s dominance index c=0.72 and 0.80 in 2002, and 0.50 and 0.53 in 2003).

The aim of this study was to determine whether bank voles Clethrionomys gla- reolus (Schreber, 1780) could be trapped by the odour of other individuals as opposed to using food as bait. A line of 100 snap traps was set at 2 meters interval in a forest. Odour bait was prepared of polyurethane foam cubes (1.5 cm3) on which few male and female bank voles were kept in a 2 litre glass jar without food and water (to prevent the transfer of food odours to the bait). Traps with even numbers were provided with the odorous foam cubes (changed every two days) and traps with odd numbers were provided with new foam. Trappings were carried out in two series in autumn, the first for 14 days and the second for 10 days. Fifty five bank voles (mean: 2.50 ±2.11 per day) were trapped in traps baited with odour foam and 14 (mean: 0.64 ± 1.36 per day) in traps without odour, the latter during the first three days of both trapping series (p < 0.001). There was no difference in the number of individuals caught on the first and second day after placing the bait with odour.

Density was estimated for three populations of eastern moles Scalopus aquaticus Linnaeus, 1758, in South Carolina using a trapping grid and assessment lines. Assessment line data were based upon the repair of holes punched into surface tunnels of the animals. Using a new method of analysis for assessment line data, a logistic curve was fitted to the data. Density estimates based upon these analyses were (95% confidence intervals in parentheses) 3.02 (1.90 - 4.98), 2.73 (1.48 - 12.52), and 1.71 (0.86 - 2.69) moles/ha. In previous studies using assessment line data to estimate density, obtaining confidence intervals for the density estimate presented theoretical problems. In this study, Monte Carlo procedures were used to obtain an estimate of the approximate 95% confidence intervals for density. The analytical methods used in the present study eliminate the concepts of boundary strip width (strict sense) and the occurrence of distinctive zones with constant capture probabilities, and as such, represent important conceptual improvements of the assessment line density estimation method.

We identified vertebrate scavengers of small mammal carcasses at the 780-km2 Savannah River Site during the winter of 2000-2001. Rodent carcasses, differing in size and visual conspicuousness, were placed in upland pine forests and bottomland hardwood forests during six 2-week periods. Sixty-two of the 96 carcasses (65%) were removed by vertebrates. With the aid of remote photography, we identified 11 species of scavengers removing carcasses. Raccoons Procyon lotor, gray foxes Urocyon cine- reoargenteus, and feral pigs Sus scrofa scavenged most frequently. The mean elapsed time for carcass removal was 5.6 days. The number of carcasses removed by vertebrates did not differ significantly with respect to carcass size, visual conspicuousness, or habitat type; however, air temperature was strongly correlated (positively) with carcass removal. Our study demonstrates that many mammal species are capable of utilizing small carrion items as a food resource, and suggests that scavenging may account for a higher proportion of the diet of some facultative scavengers than is now widely assumed.
