| higher prevalence of babesia microti than borrelia burgdorferi in small mammal species in central pennsylvania, united states. | babesia microti can lead to severe babesiosis in immunosuppressed populations, but due to high numbers of asymptomatic cases, clinical reporting is unable to define its geographic distribution. although lyme disease caused by borrelia burgdorferi is endemic throughout pennsylvania (pa), human babesiosis is under recognized, despite sharing the same vector and primary reservoir host. ixodes ticks are known to carry b. microti throughout pa, but information about pathogen prevalence in small mamma ... | 2020 | 31750805 |
| effects of trap confinement on personality measurements in two terrestrial rodents. | in recent years, consistent individual differences in behavior, or personalities, have been a topic of increasing interest as researchers strive to understand and predict the responses of individuals and populations to anthropogenic changes. behavioral studies in wild populations often require that animals are live trapped before behavioral observation can occur, and this is especially true in studies investigating animal personalities. however, it is unknown whether the amount of time confined ... | 2020 | 31986141 |
| the underappreciated role of rodent generalists in fungal spore dispersal networks. | animals are often the primary dispersers of seeds and fungal spores. specialist species that consume fruits or fungal fruiting bodies (sporocarps) as their main food source are thought to play a more important role in dispersal networks compared to generalist species. however, dispersal networks are often based on occurrence data, overlooking the influence of animal abundance and dispersal effectiveness on network interactions. using rodent-mycorrhizal fungi networks, we determined how diet spec ... | 2020 | 31943145 |
| ecological processes determining the distribution dynamics of vole populations during forest succession. | the size and distribution of animal populations may vary drastically over time following a disturbance event. while both competition and predation can control the size of animal populations, changes in the relative importance of these two density-dependent processes remain poorly documented during ecological succession. here, we combined habitat selection and optimal foraging theory to identify the processes that can explain the increase in red-backed voles (myodes gapperi) during post-logging f ... | 2018 | 30244315 |
| discovery of arostrilepis tapeworms (cyclophyllidea: hymenolepididae) and new insights for parasite species diversity from eastern north america. | species of the genus arostrilepis were discovered and definitively identified for the first time in rodents from geographically disparate localities along the appalachian mountain range of eastern north america (west virginia, virginia, and maine). these are the first confirmed records for species of arostrilepis occurring east of the rocky mountains and the mississippi river in north america. arostrilepis gardneri n. sp. is described on the basis of specimens obtained from two phylogenetically ... | 2020 | 31901996 |
| retraction: in vitro studies of interactions between frequent and unique mrnas and cytoplasmic factors from brain tissue of several species of wild timber voles of northern eurasia, clethrionomys glareolus, clethrionomys frater and clethrionomys gapperi: a new criticism to a modern molecular-genetic concept of biological evolution. | | 2020 | 31701785 |
| signaling from below: rodents select for deeper fruiting truffles with stronger volatile emissions. | many plant and fungal species use volatile organic compounds (vocs) as chemical signals to convey information about the location or quality of their fruits or fruiting bodies to animal dispersers. identifying the environmental factors and biotic interactions that shape fruit selection by animals is key to understanding the evolutionary processes that underpin chemical signaling. using four elaphomyces truffle species, we explored the role of fruiting depth, voc emissions, and protein content in ... | 2020 | 31872867 |
