| how do richness and composition of diet shape trace metal exposure in a free-living generalist rodent, apodemus sylvaticus. | exposure of terrestrial mammals to chemical contaminants like trace metals (tms) is considered to be mainly based on trophic transfer. although relationships between tm transfer to animals and identity of contaminated food have been studied, the variation of the tm transfer with respect to diet diversity has been poorly documented. in this study, the oral exposure to tms of wood mice apodemus sylvaticus was investigated with respect to both the number of different items, i.e., diet richness, and ... | 2019 | 31002242 |
| parasitic nematodes simultaneously suppress and benefit from coccidian coinfection in their natural mouse host. | within-host interactions among coinfecting parasites are common and have important consequences for host health and disease dynamics. however, these within-host interactions have traditionally been studied in laboratory mouse models, which often exclude important variation and use unnatural host-parasite combinations. conversely, the few wild studies of within-host interactions often lack knowledge of parasite exposure and infection history. here we exposed laboratory-reared wood mice (apodemus ... | 2019 | 30915927 |
| foraging, feeding, and physiological stress responses of wild wood mice to increased illumination and common genet cues. | in nature, animals are exposed to a broad range of threats imposed by predators, which may strongly influence the ecology of prey species directly or indirectly by affecting their behavior via fear of predation. here, we studied wood mice apodemus sylvaticus behavioral and physiological responses to simulated predation risk. risk avoidance was analyzed by live trapping with control traps and traps treated with feces of common genet genetta genetta (direct cue of risk) under new moon nights and f ... | 2018 | 30108622 |
| the genetic diversity of borrelia afzelii is not maintained by the diversity of the rodent hosts. | small mammals are essential in the enzootic cycle of many tick-borne pathogens (tbp). to understand their contribution to the genetic diversity of borrelia afzelii, the most prevalent tbp in questing ixodes ricinus, we compared the genetic variants of b. afzelii at three distinct genetic loci. we chose two plasmid loci, dbpa and ospc, and a chromosomal one, igs. | 2018 | 30081938 |
| does pollution influence small mammal diet in the field? a metabarcoding approach in a generalist consumer. | mammals are mainly exposed to trace metals (tms) via consuming contaminated food. several studies have demonstrated relationships between metal concentrations in food and in animal tissues. however, potential effects of tms on feeding behaviour of wildlife have been poorly documented under field conditions, despite experimental evidence showing that food selection is impacted by resource contamination. here, we test the hypothesis that the diet of a generalist rodent, the wood mouse (apodemus sy ... | 2018 | 30069953 |
| stressful living in lower-quality habitats? body mass, feeding behavior and physiological stress levels in wild wood mouse populations. | wild populations are continuously subjected to changes in environmental factors that pose different challenges. body condition and hormones have been commonly used as health indicators due to their potential correlation with fitness. in the present study, we analyzed whether habitats of different quality influenced body mass, food intake and physiological stress levels in wild wood mice (apodemus sylvaticus). field work was seasonally carried out in holm oak woods and pine forests in central spa ... | 2019 | 30019837 |
| a new fast real-time pcr method for the identification of three sibling apodemus species (a. sylvaticus, a. flavicollis, and a. alpicola) in italy. | the identification of field mice apodemus flavicollis, apodemus sylvaticus, and apodemus alpicola represents a challenge for field scientists due to their highly overlapping morphological traits and habitats. here, we propose a new fast real-time pcr method to discriminate the three species by species-specific taqman assays. primers and probes were designed based on the alignment of 54 cyt-b partial sequences from 25 different european countries retrieved from genbank. taqman assays were then te ... | 2018 | 29876059 |
| mysteries of host switching: diversification and host specificity in rodent-coccidia associations. | recent studies show that host switching is much more frequent than originally believed and constitutes an important driver in evolution of host-parasite associations. however, its frequency and ecological mechanisms at the population level have been rarely investigated. we address this issue by analyzing phylogeny and population genetics of an extensive sample, from a broad geographic area, for commonly occurring parasites of the genus eimeria within the abundant rodent genera apodemus, microtus ... | 2018 | 29753710 |
| the helminth community component species of the wood mouse as biological tags of a ten post-fire-year regeneration process in a mediterranean ecosystem. | serra calderona natural park, a mediterranean ecosystem, has been in post-fire regeneration for 10 years. to elucidate which helminth community component species of the wood mouse, apodemus sylvaticus, can be considered biological tags of this process, the influence of intrinsic (host density; host sex and age) and extrinsic factors (site, year, and period of capture; vegetation recovery) on their prevalence and abundance has been analysed, comparing a burned and an unburned area. a total of 564 ... | 2018 | 29744702 |
| the immune and non-immune pathways that drive chronic gastrointestinal helminth burdens in the wild. | parasitic helminths are extremely resilient in their ability to maintain chronic infection burdens despite (or maybe because of) their hosts' immune response. explaining how parasites maintain these lifelong infections, identifying the protective immune mechanisms that regulate helminth infection burdens, and designing prophylactics and therapeutics that combat helminth infection, while preserving host health requires a far better understanding of how the immune system functions in natural habit ... | 2018 | 29459856 |
| support vector machines for explaining physiological stress response in wood mice (apodemus sylvaticus). | physiological stress response is a crucial adaptive mechanism for prey species survival. this paper aims to identify the main environmental and/or individual factors better explaining the stress response in wood mice, apodemus sylvaticus. we analyzed alterations in fecal glucocorticoid metabolite (fcm) concentration - extensively used as an accurate measure of the physiological stress response - of wild mice fecal samples seasonally collected during three years. then, support vector machines wer ... | 2018 | 29416078 |

| age affects antibody levels and anthelmintic treatment efficacy in a wild rodent. | the role of the host immune system in determining parasite burdens and mediating within-host parasite interactions has traditionally been studied in highly controlled laboratory conditions. this does, however, not reflect the diversity of individuals living in nature, which is often characterised by significant variation in host demography, such as host age, sex, and infection history. whilst studies using wild hosts and parasites are beginning to give insights into the complex relationships bet ... | 2019 | 30923672 |
| pathogenic leptospira species in rodents from corsica (france). | leptospirosis is a worldwide emerging zoonotic disease caused by leptospira species, that in some patients develop severe forms with high mortality. in france, corsica is the area where the highest incidences have been reported. the present study was focused on the analysis of pathogenic leptospira species in rodents of corsica, as these micromammals are the main natural reservoirs of the bacteria, in order to identify the circulating species and to locate possible risk focuses of transmission, ... | 2020 | 32502160 |
| prevalence and genotype identification of toxoplasma gondii in suburban rodents collected at waste disposal sites. | to assess the prevalence of toxoplasma gondii infection in native and commensal rodents as indicators of environmental pollution, we analyzed brain tissue from small mammals collected on legal and illegal waste sites in the slovenian and croatian parts of istria. a total of 136 animals and five species of the family muridae were analyzed: black rat (rattus rattus), domestic mouse (mus musculus), wood mouse (apodemus sylvaticus), striped field mouse (apodemus agrarius), and yellow-necked mouse (a ... | 2019 | 31041898 |
| who acquires infection from whom? estimating herpesvirus transmission rates between wild rodent host groups. | to date, few studies of parasite epidemiology have investigated 'who acquires infection from whom' in wildlife populations. nonetheless, identifying routes of disease transmission within a population, and determining the key groups of individuals that drive parasite transmission and maintenance, are fundamental to understanding disease dynamics. gammaherpesviruses are a widespread group of dna viruses that infect many vertebrate species, and murine gammaherpesviruses (i.e. muhv-4) are a standard ... | 2021 | 33761448 |
