Using microstructures and composition to decipher the alterations of rodent teeth in modern regurgitation pellets—a good news-bad news story

open access: yes, 2020
Rodent accumulations are widely used for palaeoenvironmental reconstructions. But these accumulations are created through the activity of predators (carnivorous mammals, birds of prey), the predation and digestion of which modify the preservation of ...

Alarm Calling in Plateau Pika (Ochotona curzoniae): Evidence from Field Observations and Simulated Predator and Playback Experiments

open access: yesAnimals, 2023
Acoustic communication plays a vital role in passing or sharing information between individuals. Identifying the biological meaning of vocal signals is crucial in understanding the survival strategies of animals.

Comparative analysis of rodent and small mammal viromes to better understand the wildlife origin of emerging infectious diseases

open access: yesMicrobiome, 2018
Rodents represent around 43% of all mammalian species, are widely distributed, and are the natural reservoirs of a diverse group of zoonotic viruses, including hantaviruses, Lassa viruses, and tick-borne encephalitis viruses.

Machine learning identifies straightforward early warning rules for human Puumala hantavirus outbreaks

open access: yesScientific Reports, 2023
Human Puumala virus (PUUV) infections in Germany fluctuate multi-annually, following fluctuations of the bank vole population size. We applied a transformation to the annual incidence values and established a heuristic method to develop a straightforward

Rodent systematics in an age of discovery: recent advances and prospects

open access: yesJournal of Mammalogy, 2019
With almost 2,600 species, Rodentia is the most diverse order of mammals. Here, we provide an overview of changes in our understanding of the systematics of living rodents, including species recognition and delimitation, phylogenetics, and classification,

Presence of Salmonella and Campylobacter spp. in Wild Small Mammals on Organic Farms [PDF]

open access: yes, 2005
The presence of Salmonella and Campylobacter spp. in rodents and insectivores (n 282) was investigated on organic farms. Infections were encountered in house mice (8 of 83 Campylobacter positive and 1 of 83 Salmonella sp.

Diffusion and Home Range Parameters from Rodent Population Measurements in Panama

open access: yes, 2005
Simple random walk considerations are used to interpret rodent population data collected in Hantavirus-related investigations in Panama regarding the short-tailed cane mouse, \emph{Zygodontomys brevicauda}.

Small and large intestine express a truncated Dab1 isoform that assembles in cell-cell junctions and co-localizes with proteins involved in endocytosis [PDF]

open access: yes, 2018
Disabled-1 (Dab1) is an essential intracellular adaptor protein in the reelin pathway. Our previous studies in mice intestine showed that Dab1 transmits the reelin signal to cytosolic signalling pathways.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Effects of overgrazing on the functional diversity of rodents in desert areas

open access: yesEcology and Evolution
Environmental stressors and disturbances can cause changes in an ecosystem's community structure, which can be reflected in its functional diversity. As grazing intensity increases, this causes changes in the environment that inevitably lead to changes ...
