Abstract:

Four-year microtine population density cycles are extreme in northern Fennoscandia. We studied populations of wood lemmings (Myopus schisticolor) and bank voles (Clethrionomys glareolus) in the peak phase and subsequent crash phase at two localities, Varaldskogen and Risberget, Norway. Bank voles at Varaldskogen and bank voles and wood lemmings at Risberget crashed during the nonreproductive period in winter when we were not trapping animals. Wood lemmings at Varaldskogen, however, crashed during the reproductive period in summer. Reproduction in the wood lemming population was as intense during the summer crash as in the peak phase. Further, survival of overwintered animals was the same in peak populations and in the population undergoing the crash. However, lack of recruitment was the cause of the summer crash of the wood lemming population. Poor nutrition is the most likely cause of the lack of recruitment.

Abstract:

The wood lemming, Myopus schisticolor, was described as a new species by the Swedish zoologist Wilhelm Lilljeborg in 1844 from a specimen captured in Norway the year before. With the original description was a fine hand-coloured lithograph by the artist Magnus Körner. A Latin translation of the description published later that year also used an illustration by Körner, but it was of lesser quality. However, the species had been observed, described and depicted earlier, but these renderings never reached the scientific community. In 2008 and 2009 respectively, one illustration of the wood lemming made by the Finnish-born artist Wilhelm von Wright was sold twice at auctions in Stockholm. The illustration is dated 1834 and shows a specimen that was found dead at the artist's native home, Haminalaks, in Kuopio parish, Central Finland, that year. However, an accurate description of the species had already been made in 1765, by a group of young naturalists on a tour in the Swedish province Dalecarlia.

Abstract:

A rich sedimentary deposit reaches a depth of more than 4 m in a cave located on the Eardley Escarpment in the Gatineau Park. Analysis shows that the infilling started during the last Ice Age. Following the deglaciation and the Champlain Sea retreat, terrestrial sedimentation began. Radiocarbon dating of wood charcoal indicates that around 9200 ± 110 years BP trees and shrubs were starting to grow on the Eardley Escarpment. A fauna, with boreal affinity, including the Ungava collared lemming (Dicrostonyx hudsonius), was living in vegetation dominated by jack pine. After 8170 ± 60 years BP, the boreal forest was replaced by a mixed forest dominated by white pine, oak, and red maple. The faunal assemblage was enriched at that time by woodland vole (Microtus pinetorum) and Strobilops aenea, a terrestrial mollusk. These two species are presently living in the Carolinian Life Zone south of the Great Lakes. By around 5742 ± 120 years BP these two species had left the site, and the modern fauna was established with mammals, such as the black bear and the white-tailed deer. Holocene infilling of the cave was gravity driven and unassisted, except for an episode just before 8170 ± 60 years BP when a sand layer was deposited by water coming from the surface.

Abstract:

AbstractSediments exposed at Epiguruk, a large cutbank on the Kobuk River about 170 km inland from Kotzebue Sound, record multiple episodes of glacial-age alluviation followed by interstadial downcutting and formation of paleosols. Vertebrate remains from Epiguruk include mammoth, bison, caribou, an equid, a canid, arctic ground squirrel, lemmings, and voles. Radiocarbon ages of bone validated by concordant ages of peat and wood span the interval between about 37,000 and 14,000 yr B.P. The late Pleistocene pollen record is dominated by Cyperaceae, with Artemisia, Salix, Betula, and Gramineae also generally abundant. The fossil record from Epiguruk indicates that the Kobuk River valley supported tundra vegetation with abundant riparian willows during middle and late Wisconsin time. Large herbivores were present during the height of late Wisconsin glaciation as well as during its waning stage and the preceding interstadial interval. The Kobuk River valley would have been a favorable refugium for plants, animals, and possibly humans throughout the last glaciation.

Abstract:

Dwindling stocks of decaying coarse woody debris (CWD), as a result of forest management and growing interest for biofuels, may jeopardize the persistence of a broad spectrum of organisms such as small mammals. In this study, we quantified the effects of CWD in late-decay stages on the occupancy dynamics of small mammals in managed and unmanaged boreal forests. Probabilities of initial site occupancy, colonization, local extinction, and co-occurrence were modelled for five boreal small mammal species. Southern red-backed voles (Myodes gapperi Vigor) and southern bog lemmings (Synaptomys cooperi Baird) were more likely to occupy sites with high volumes of late-decay CWD early in the summer. The probability of local extinction for deer mice (Peromyscus maniculatus Wagner) slightly decreased with an increasing volume of late-decay CWD in harvested sites. Southern red-backed voles and meadow voles (Microtus pennsylvanicus Ord) co-occurred more often in old, uncut forests, as well as harvested sites with high volumes of late-decay CWD. These results suggest that cover provided by late-decay CWD benefited two small rodent species during early reproduction and increased persistence of deer mice later in the summer. Finally, we found that in addition to high live-tree basal areas, high late-decay CWD volume also favours local diversity of small mammals.

Abstract:

Both mouse and man have the common XX/XY sex chromosome mechanism. The X chromosome is of original size (5-6% of female haploid set) and the Y is one of the smallest chromosomes of the complement. But there are species, belonging to a variety of orders, with composite sex chromosomes and multiple sex chromosome systems: XX/XY 1 Y 2 and X 1 X 1 X 2 X 2 /X 1 X 2 Y. The original X or the Y, respectively, have been translocated on to an autosome. The sex chromosomes of these species segregate regularly at meiosis; two kinds of sperm and one kind of egg are produced and the sex ratio is the normal 1:1. Individuals with deviating sex chromosome constitutions (XXY, XYY, XO or XXX) have been found in at least 16 mammalian species other than man. The phenotypic manifestations of these deviating constitutions are briefly discussed. In the dog, pig, goat and mouse exceptional XX males and in the horse XY females attract attention. Certain rodents have complicated mechanisms for sex determination: Ellobius lutescens and Tokudaia osimensis have XO males and females. Both sexes of Microtus oregoni are gonosomic mosaics (male OY/XY, female XX/XO). The wood lemming, Myopus schisticolor , the collared lemming, Dicrostonyx torquatus , and perhaps also one or two species of the genus Akodon have XX and XY females and XY males. The XX, X*X and X*Y females of Myopus and Dicrostonyx are discussed in some detail. The wood lemming has proved to be a favourable natural model for studies in sex determination, because a large variety of sex chromosome aneuploids are born relatively frequently. The dosage model for sex determination is not supported by the wood lemming data. For male development, genes on both the X and the Y chromosomes are necessary.

Abstract:

Abstract One of the less studied positive interactions among organisms is facilitation. Facilitation may have significant impact on diversity of species especially in low productive environments. We studied the effects of well-known facilitator and ecosystem engineer, the North American beaver (Castor canadensis), on small mammal assemblages in the boreal zone. The small mammals, namely voles, mice, and shrews, were trapped over 2 years in ten beaver-modified habitats and in ten control sites. Contrary to our expectations, we did not observe any differences between species or individual numbers between beaver-modified and control sites. However, there were differences in species composition between sites; grass-eating field voles (Microtus agrestis) and invertebrate-eating shrews (Sorex araneus, Neomys fodiens) tended to be more common in beaver sites while forest-dwelling wood lemmings (Myopus schisticolor) and yellow-necked mice (Apodemus flavicollis) were only captured in control sites. The most common species in both habitats was the bank vole (Myodes glareolus), which is a generalist in its habitat requirements. The bank vole’s population structures were similar between the two habitat types. The actions of beavers in water bodies within boreal forests seem to have no effect on the small mammal diversity and their numbers at the regional scale but may have positive effect on them at the larger landscape level as beavers are increasing the overall habitat diversity in the landscape.
