Infanticide, the killing of nonspecific young, has been documented in numerous species mammals and is considered an adaptive behavioral strategy to enhance reproductive success perpetrator. The potential benefits committing infanticide for males are obtaining nutritional gain mating partners, females acquiring access resources such as food nest sites. Some costs associated with additional energy expenditure, risk injury, exposure predation. However, major borne by victim female sire male...
Current life-history theory predicts that increased mortality at early stages of life leads to reduced initial investment (e.g. clutch size) but subsequent during the reproduction attempt. In a field experiment, migratory pied flycatchers Ficedula hypoleuca perceived differences in mammalian nest predation risk and altered their reproductive strategies two respects. First, birds avoided sites manipulated reflect presence predator. Second, breeding risky areas nested 4 days earlier laid 10...
1. Although spacing behaviour in small mammals has been studied extensively, the ultimate function of territoriality females is frequently under debate. Furthermore, almost no data exists on how territorial changes during reproductive cycles and that affects their success. We these questions large outdoor enclosures using bank vole Clethrionomys glareolus as a study species. 2. Home range dynamics territory owners against intruder were determined four distinct periods cycle: (i) when...
The bank vole Clethrionomys glareolus (Schreber), was studied in enclosures and on islands Central Finland 1982-88. Winter breeding observed 1983-84 1986-87, both of which were years increasing microtine populations. No mustelids the study areas during these winters. Local populations peaked 1987-88. However, when voles kept large at fairly low densities winter, female found to have perforated vaginae males scrotal testes by February 1988. first litters born as late two a half months later....
In 2015 a long-term, nationwide tick and tick-borne pathogen (TBP) monitoring project was started by the Finnish Tick Project Research Station network (RESTAT), with goal of producing temporally geographically extensive data regarding exophilic ticks in Finland. current study, we present results from first four years this collaboration. Ticks were collected cloth dragging 11 research stations across Finland May-September 2015-2018 (2012-2018 Seili). Collected screened for twelve different...
The potential reproductive costs for free-ranging bank vole (Clethrionomys glareolus) offspring and mothers were assessed by manipulating litter size determining the effects of nursing varied numbers offspring. Litter enlargement did not increase number weanlings per mother. mass juveniles was significantly lower in enlarged litters higher reduced litters, compared to control group. However, survival from weaning aged three months depend on their at weaning. Data a previous study (Mappes et...
SUMMARY The deer ked ( Lipoptena cervi ) is a haematophagous ectoparasite of cervids that harbours haemotrophic Bartonella . A prerequisite for the vector competence vertical transmission pathogen from mother to its progeny and transstadial pupa winged adult. We screened 1154 pupae 59 pools adult keds different areas in Finland DNA using PCR. Altogether 13 samples one were positive presence DNA. amplified sequences closely related either B. schoenbuchensis or bovis. same lineages identified...
Many prey animals have life-history strategies that seem to evolved avoid predation from specialist predators. During the past few years. hypothesis of breeding suppression (BSH) voles as an adaptation small mustelid has prompted several empirical and theoretical studies. However, validity work well justification conclusions in these studies been criticised. Here we report results experiment which studied bank voles, Clethrionomvs glareolus. four replicated enclosures. We found no effects...
We studied habitat selection and foraging behaviour of the house mouse ( Mus domesticus ) related to increasing densities depleting food resources over breeding season. The study was conducted during increase phase an incipient outbreak mice in a grain‐growing area southeastern Australia. A 3‐year rotation created mosaic large paddocks grain crop, pasture, fallow. narrow fence lines between provide important stable for mice. monitored population with live‐trapping preference by measuring...
According to the kin selection theory degree of genetic relatedness affects nature intraspecific competition and it might promote cooperative and/or altruistic behavior between individuals. We examined kinship effects on reproductive success territorial females survival juveniles in bank vole Clethrionomys glareolus. Four experimental populations were founded large enclosures (0.5 ha): two consistent five related (Related, R) mutually unrelated (Unrelated, UR). Each population had males...
We studied the predation rate and prey selection of least weasel ( Mustela nivalis ) on its two most common species in boreal environments, bank vole Clethrionomys glareolus field Microtus agrestis ), large outdoor enclosures. also response weasels to odours laboratory. The enclosure experiment was conducted using constant densities (16 voles/ha) but with varying relative abundance species. Weasels showed higher rates voles, males had than females. Females killed disproportionately more...
The social organization of Clethrionomys glareolus Schreber was studied by live trapping in an enclosure 0.8 ha Central Finland between the years 1982–1986. consisted three habitats: abandoned field, brushwood, and moist spruce heath forest. population density increased from 50 voles −1 1982 1983 to 150 1984 1985. In summer 1986 crashed almost zero. after winter breeding number females grew 22 compared with 6–7 previous years. mature changed territorial group behaviour. During high 1985...
Abstract The deer ked ( Lipoptena cervi ) can fail in its host search. Host search fails when an individual irreversibly accepts a unsuitable for reproduction (e.g. human) and drops wings. In northern Europe, the main of is moose Alces alces ). increasingly causing serious problems humans (for example, dermatitis) considered threat recreational use forests. adult flies early mid-autumn to host. Our aims were: (i) study whether there are ways avoid attacks by wearing particular clothing, (ii)...
The range expansion of organisms towards higher latitudes and altitudes is often limited by colder temperatures the shorter growth season. In parasites, survival outside host most likely to affect their potential establishment in novel environments. We conducted a large scale transplant experiment predict spread deer ked Lipoptena cervi (Diptera: Hippoboscidae), blood‐feeding ectoparasite boreal cervids. studied off‐host pupal development five sites along latitudinal gradient reaching from...
