Small mammal populations in a restored stream corridor

ABSTRACT: The samples collected by traps in the vicinity of Temerin and the analysis of pellets of the long-eared owl (Asio otus) and the barn owl (Tyto alba) served as a basis for the determination of 409 individuals of small mammals of the orders Insectivora and Rodentia. A total of 13 species

ABSTRACT- The abundance and similarity of communities of small mammals (rodents and shrews) were investigated in eight habitats in the Mikumi National Park. A total of 767 individuals, belonging to 21 species and 6 families was captured by three types of live traps. The per cent abundance

ABSTRACT- Extensive descriptive, comparative, and experimental research on the chromosomes of natural populations of small mammals has been conducted in the last 50 years. These studies have re-vealed a surprisingly large amount of karyotypic variation within and between individuals, popula-tions

Estimates of body condition in mammals may be constructed from measures of skeletal size and body mass. We illustrate the methodology for doing this using data from two populations of feral house mice (Mus domesticus) in Australia, and point out an erroneous method that has commonly been used

ABSTRACT. The paper reports on 3800 small mammals taken in taiga and tundra east of the Mackenzie River Delta between 1971 and 1974. Local distributions are given for all 10 species of small mammals recorded in the region, plus two accidentals. In addition, abundance, body and cranial

Abstract: Small mammal species richness, abundance and biomass were determined in representative S.W. Cape montane fynbos habitats of various post-fire ages, and in riverine and rocky outcrop habitats respectively too wet and too poorly vegetated to burn. In fynbos the parameters measured displayed

Influence of vegetation structure on the small mammal community in a shortgrass prairie ecosystem

unlogged and logged native forest and from exotic forest at Pureora Forest Park, in the central North Island of New Zealand. Sex ratio, litter size, and breeding effort (pregnancy rate in females, proportion of males with visible tubules) were similar in all samples. By contrast, both density (captures per 100 trap-nights = C/ 100TN) and recruitment (proportion of young mice of age classes 1-3) were higher in densely vegetated habitats (along the road edge or in a young exotic plantation) than in the forest interior, whether logged or not. The age structures of the road edge and interior forest samples were significantly different (road edge, 33-35 % young; interior, 10-11 % young, means adjusted for sex, season and year by GLM). Mice of a given age caught in summer were larger, especially the females, implying that young mice grew faster in summer than at other seasons, and that older mice, especially females, also put on extra weight in summer. Most pregnant mice were found in spring and summer, but there was no winter quiescence in mature mice of either sex, and three of 29 pregnant females were collected in August. In five of 29 litters of embryos, at least one embryo was resorbing, totalling 12 of 161 embryos (7.4%). Litter size (viable embryos only) ranged from 5 to 8 (average 6) in 23 spring and summer pregnancies, but only 1-5 in four autumn and winter pregnancies. At high densities during 1984 in the young plantation (41.1 C/100TN in May) mice were significantly smaller in autumn, though somewhat larger in spring, and fewer young were recruited in 1984 and 1985.
