New Information

New information on the diet of Dasyurus viverrinus from one locality in southern Tasmania is presented. A total of 64 droppings from 41 animals were collected during 3 intervals over 8 months and examined microscopically. Insects constituted the bulk of the diet and occurred in 97% of the droppings. The remains of birds and small mammals were found in 17% of the droppings. All droppings contained similar amounts of plant material. Seasonal changes in the contribution of different species of prey to the diet of native cats are discussed.

Nest Chamber

THE most detailed information on the burrows and nests of Australian small mammals are reported by Watts and Aslin (1981). The nests of several species of Pseudomys have been described and vary between species. Three nests of the New Holland mouse Pseudomys novaehollandiae were excavated from sand burrows and described as being partially comprised of Eucalypt leaves (Kemper 1981). In South Australia, silky mice P. apodemoides construct nests of shredded bark within a nest chamber of approximately 15 cm (Watts and Aslin 1981). The desert mouse P. desertor reputedly builds dry grass nests in shallow constructions (Read et al.1999) and the long-tailed mouse P. higginsi and eastern chestnut mouse P. gracilicaudatus, delicate mouse P. delicatulus and Gould?s mouse P. gouldii all construct nests of plant material (Watts and Aslin 1981; Green 1993; Fox 1995) mostly grass. The nests of the smokey mouse P. fumeus are constructed of dried grass and Allocasuarina needles that are shaped in a cup form (10-15cm in diameter) (Woods and Ford 2000).

ABSTRACTA total of 392 small mammals belonging to five species of small rodents and four species of shrews were caught. The small mammals and their percentage composition were Crocidura nigeriae (20.9%), Crocidura grandiceps (11.7%), Crocidura crossei (9.7%), Crocidura flavescens manni (20.4%), Mus musculoides (39.0%), Praomys tullbergi (11.5%), Lophuromys sikapusi (3.6%), Lemniscomys striatus (1.3%), and Arvicanthis niloticus (0.3%).There were monthly variations in the number of Mus musculoides and Crocidura nigeriae.In Mus musculoides breeding was at a maximum at the beginning and towards the end of the wet season and early dry season. In Crocidura nigeriae breeding was maximal during the wet season and low in the dry season.The seasonal changes in the age structure of the two most common species: Mus musculoides and Crocidura nigeriae, are described.

Mammal Diversity

The validity of using single-sample surveys to measure small mammal diversity was assessed by measuring the effect of short-term, temporal variation in species diversity on the spatial diversity of small mammals occupying fencerow habitats. The diversity of small mammals varied seasonally. Interaction between changes in richness and evenness accounted for the temporal variation in diversity. Temporal variation was attributed to the response of the small mammals to seasonal changes in the vegetation, to the fluctuation in meadow vole (Microtus pennsylvanicus) captures among seasons, and to the appearance of small numbers of several mammal species during the summer. Significant spatial variation in species diversity existed, but was masked by the effect of seasonal changes in habitat on the small mammals. Erroneous conclusions could therefore be drawn from the pooling of many single-sample surveys of small mammal diversity.

Seasonal Acclimatization

Seasonal changes in insulation of the fur have been compared in nine species of arctic and North temperate zone mammals. Relative seasonal changes ranged from 12 to 52% of the winter value. Absolute changes were greatest in the larger mammals with thickest fur. The limited seasonal insulative change in small mammals suggests that changes in heat production may be important in seasonal acclimatization.

ABSTRACT New information has resulted from studies comparing the genetic behavior of two experimental cultures, termed variegated-3 and variegated-1, which arose earlier following an interspecific cross. Phenotypic expression in the plant material involves distinctive variegation patterns of anthocyanin distribution in floral tissues.—The data are consistent with the hypothesis that the genetic constitution of variegated-3 includes a unique and independently segregating regulator component, Flt(3), in addition to the v locus element held in common with variegated-1. Flt(3) has not been generated anew within the variegated-1 genotypes among more than 10,000 observed progeny. Presence of Flt(3) modifies the timing of somatic sectoring events, and is correlated with the capability to produce, in germ cell lines of phenotypically flecked plants, frequent changes at the v locus to a stable, non-variegating, dominant allelic form, V.—The latter process is of special interest because progeny tests of mutant individuals, containing newly-arisen V alleles, fail to reveal continued presence of Flt(3). Thus the mechanism generating V from v appears to be correlated invariably with loss or inactivation of the controllingelementinducing this class of mutations, which is located initially on a different chromosome from that bearing v.

Occurrence Records

The dataset contains records of small mammals (Eulipotyphla and Rodentia) collected in the background (unpolluted) areas in the vicinity of Karabash copper smelter (Southern Urals, Russia) and the territory of the Sultanovskoye deposit of copper-pyrite ores before the start of its development. Data were collected during the snowless periods in 2007 (18 sampling plots), 2008–2010 (13 plots annually), 2011 (30 plots) and 2012–2014 (19 plots annually). The capture of animals was carried out in different types of forests (pine, birch, mixed and floodplain), sparse birch stands, reed swamps, marshy and dry meadows, border areas, a household waste dump, areas of ruderal vegetation and a temporary camp. Our study of small mammals was conducted using trap lines (snap and live traps). During the study period, 709 specimens of small mammals were caught, which belonged to five species of shrews and 13 species of rodents. The dataset may be highly useful for studying regional fauna and the distribution of species in different habitats and could also be used as reference values for environmental monitoring and conservation activities. Our dataset contains new information on occurrences of small mammals. It includes the peculiarities of their habitat distribution in the background areas in the vicinity of the large copper smelter and the deposit of copper-pyrite ores before the start of its development (Chelyabinsk Oblast, Russia). All occurrence records of 18 mammal species with georeferencing have been published in GBIF.

Tundra Vole

Ecological interactions between ungulates and small mammals are generally not well understood. Here, we report an observation of unusually extensive small mammal (likely Meadow Vole [Microtus pennsylvanicus] or Tundra Vole [Microtus oeconomus]) tracks above the snow, exiting from trails and bed sites created by Bison (Bison bison) in northern Canada. We believe that weather and snow conditions were optimal for this observation. Although alteration of above-snow activity of small mammals in response to snow compaction by ungulates is probably not a rare event, it is not often reported. The effect on voles of exiting their subnivean tunnels as a result of Bison activity is unclear, but may be detrimental to their overwinter survival. Ungulate activity compacts snow, fragmenting small mammal tunnels resulting in loss of their insulative value for voles, and making it harder for them to dig new tunnels. Clearly, determining the effect of snow disturbance by gregarious ungulates on voles or other microtines, particularly regarding their overwinter survival, requires detailed investigation. Nevertheless, this observation provides new information on the ecological interactions between ungulates and small mammals, particularly from the boreal forest, where such information is largely lacking.
