Deer Mice

When given the choice between traps with or without a mixture of peanut butter and oats (peanut butter balls), deer mice (Peromyscus maniculatus) preferred the former. However, trappability of deer mice was not affected by the presence of peanut butter balls. Acceptable food in live traps is essential to successful trapping of small mammals as these animals will systematically return to traps for food. The peanut butter and oatmeal mixture would increase the nutritional and possibly water content of food in the trap and is thus recommended for deer mouse trapping.

Heat Shock Responses

In North America, Sin Nombre virus (SNV) is the main cause of hantavirus cardiopulmonary syndrome (HCPS), a severe respiratory disease with a fatality rate of 35–40%. SNV is a zoonotic pathogen carried by deer mice (Peromyscus maniculatus), and few studies have been performed examining its transmission in deer mouse populations. Studying SNV and other hantaviruses can be difficult due to the need to propagate the virus in vivo for subsequent experiments. We show that when compared with standard intramuscular infection, the intraperitoneal infection of deer mice can be as effective in producing SNV stocks with a high viral RNA copy number, and this method of infection provides a more reproducible infection model. Furthermore, the age and sex of the infected deer mice have little effect on viral replication and shedding. We also describe a reliable model of direct experimental SNV transmission. We examined the transmission of SNV between deer mice and found that direct contact between deer mice is the main driver of SNV transmission rather than exposure to contaminated excreta/secreta, which is thought to be the main driver of transmission of the virus to humans. Furthermore, increases in heat shock responses or testosterone levels in SNV-infected deer mice do not increase the replication, shedding, or rate of transmission. Here, we have demonstrated a model for the transmission of SNV between deer mice, the natural rodent reservoir for the virus. The use of this model will have important implications for further examining SNV transmission and in developing strategies for the prevention of SNV infection in deer mouse populations.

Feasible Alternative

Abstract Estimating population densities of small mammals (< 100g) has typically been carried out by intensive livetrapping, but this technique may be stressful to animals and the effort required is considerable. Here, we used camera traps to detect small mammal presence and assessed if this provided a feasible alternative to livetrapping for density estimation. During 2010–2012, we used camera trapping in conjunction with mark–recapture livetrapping to estimate the density of northern red-backed voles ( Myodes rutilus ) and deer mice ( Peromyscus maniculatus ) in the boreal forest of Yukon, Canada. Densities for these 2 species ranged from 0.29 to 9.21 animals/ha and 0 to 5.90 animals/ha, respectively, over the course of this investigation. We determined if hit window—the length of time used to group consecutive videos together as single detections or “hits”—has an effect on the correlation between hit rate and population density. The relationship between hit rate and density was sensitive to hit window duration for Myodes with R2 values ranging from 0.45 to 0.59, with a 90-min hit window generating the highest value. This relationship was not sensitive to hit window duration for Peromyscus , with R2 values for the tested hit windows ranging from 0.81 to 0.84. Our results indicate that camera trapping may be a robust method for estimating density of small rodents in the boreal forest when the appropriate hit window duration is selected and that camera traps may be a useful tool for the study of small mammals in boreal forest habitat.

Stomach Weight

The frequency distribution of over 600 stomach weights of deer mice showed considerable variation and was highly skewed. Because of the difficulty of defining a "full" stomach, it was not possible to use the weights of stomachs sampled to estimate consumption rates. There were no significant seasonal changes in mean stomach weights over a 3-year study and no relationship between stomach weights and sexual condition was found.

Pentobarbital Anaesthesia

This study demonstrates the effect of sodium pentobarbital anaesthesia on heart rate (HR) and blood distribution (Sapirstein method) in the deer mouse, Peromyscus maniculatus, and in the big brown bat, Eptesicus fuscus.Resting HR's average 400 beats/min and 334 beats/min in deer mice and bats, respectively. Administration of 40 mg/kg sodium pentobarbital results in marked tachycardia in deer mice but not in bats. A dose of 60 mg/kg causes a slight increase of HR above resting values in the mice and a significant decrease in the bats. The comparatively low HR's in bats are considered to be due to their lowering of body temperature to near environmental levels.The general pattern of blood distribution is comparable between the two species investigated. Sodium pentobarbital administration results in a pronounced redistribution of blood which includes an increase in the fractional delivery of cardiac output to viscera of the abdomen primarily at the expense of skeletal muscle.

Mammal Communities

There are often several rodent species included in the small mammal communities in orchard agro-ecosystems. This study was designed to test the hypothesis that the population levels of Deer Mice (Peromyscus maniculatus) and Yellow-pine Chipmunks (Tamias amoenus) would be enhanced in old field compared with orchard habitats. Rodent populations were intensively livetrapped in replicate old field and orchard sites over a four-year period at Summerland, British Columbia, Canada. Deer Mouse populations were, on average, significantly higher (2.5 – 3.4 times) in the old field than orchard sites in summer and winter periods. Mean numbers/ha of Deer Mice ranged from 12.1 to 60.4 in old field sites and from 3.3 to 19.9 in orchard sites. Breeding seasons in orchards were significantly longer than those in old field sites, in terms of proportion of reproductive male Deer Mice. Recruitment of new animals and early juvenile survival of Deer Mice were similar in orchard and old field sites. Populations of Yellow-pine Chipmunks ranged in mean abundance/ha from 5.6 – 19.0 in old field sites and from 1.9 – 17.5 on one orchard site, with no difference in mean abundance in 2 of 4 years of the study. Recruitment and mean survival of Yellow-pine Chipmunks also followed this pattern. This study is the first detailed comparison of the population dynamics of these rodent species in old field and orchard habitats. These species should be able to maintain their population levels and help contribute to a diversity of small mammals in this agrarian landscape.

Prairie Long-tailed Weasels (Mustela frenata longicauda) were live-trapped during fall 2005, 2006, and 2007 at Pine Coulee Reservoir and during fall 2005, 2008, and 2010 at Twin Valley Reservoir in southwestern Alberta. Our objective was to estimate the relative abundance of the Long-tailed Weasel and to estimate the relative abundance of small mammal prey. Body size and capture rates are reported for Long-tailed Weasels, and we report capture rates of small mammals. Annual capture rates for Long-tailed Weasels at Pine Coulee Reservoir were 0.44, 0.41, and 0.50 individuals per 100 corrected trap-nights (0.42, 0.38, and 0.48 individuals/100 trap-nights) in 2005, 2006, and 2007, respectively. No Long-tailed Weasels were captured at Twin Valley Reservoir. The probability of capturing zero Long-tailed Weasels at Twin Valley Reservoir was very low, assuming a true capture probability equivalent to that observed at Pine Coulee Reservoir. Deer Mice (Peromyscus maniculatus) were the most abundant small mammals captured in both project areas. Few shrews (Sorex spp.) and voles (Microtus spp.) were captured in either area.

Naturally Occurring

Effects of habitat isolation can differ among species, thereby influencing populations both directly and indirectly. We used naturally occurring forest patches surrounded by a sage–steppe matrix in southeast Idaho to test the hypothesis that a habitat specialist, the red-backed vole (Clethrionomys gapperi), would have movements restricted and therefore population densities reduced on forest patches isolated by distances equal to or greater than their typical home-range diameter. We hypothesized that the more generalized deer mouse (Peromyscus maniculatus) would not show effects of isolation at this scale. We tested for effects of isolation on these small mammals in 1999 and 2000 in forest patches that varied in distance to a mainland forest. Densities of red-backed voles decreased with isolation and those of deer mice did not. However, strong relationships were also found between red-backed vole densities and habitat characteristics, which themselves varied with isolation. Livestock apparently had disproportionate effects on the more isolated patches, thereby altering ground cover. Isolation by distances up to 450 m appears to reduce (filter) rather than eliminate immigration of red-backed voles; however, effects of livestock on isolated habitat patches may prevent successful dispersers from populating patches.

Virus Strains

Phylogeographical partitioning of Sin Nombre and Monongahela viruses (hantaviruses) may reflect that of their primary rodent host, the deer mouse (Peromyscus maniculatus). Lack of a comprehensive assessment of phylogeographical variation of the host has precluded the possibility of predicting spatial limits of existing strains of these viruses or geographical regions where novel viral strains might emerge. The complete cytochrome b gene was sequenced for 206 deer mice collected from sites throughout North America to provide a foundation for future studies of spatial structure and evolution of this ubiquitous host. Bayesian analyses of these sequences partitioned deer mice into six largely allopatric lineages, some of which may represent unrecognized species. The geographical distributions of these lineages were probably shaped by Quaternary climatic events. Populations of mice were apparently restricted to refugia during glacial advances, where they experienced genetic divergence. Expansion of these populations, following climatic amelioration, brought genetically distinctive forms into contact. Occurrence of parallel changes in virus strains can now be explored in appropriate regions. In New Mexico, for example, near the location where Sin Nombre virus was first discovered, there are three genetically distinctive lineages of deer mice whose geographical ranges need to be delineated precisely. The phylogeography of P. maniculatus provides a framework for interpreting geographical variability, not only in hosts, but also in associated viral variants and disease transmission, and an opportunity to predict the potential geographical distribution of newly emerging viral strains.

Karyotype Analyses

Karyotype analyses of eight animals from an interbreeding colony of three subspecies of Peromyscus maniculatus (P.m. gambelli, P.m. rubidus, and P.m. sonoriensis) demonstrated a chromosomal polymorphism, probably due to pericentric inversions involving at least seven chromosomes. This polymorphism may require consideration in the cytogenetic taxonomy of these animals, and may be related to the widespread distribution of deer mice in North America and their apparent adaptability to many different environments.
