  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • In a crowded environment the natal territory could serve as a haven for young and inexperienced offspring until a breeding vacancy emerges. Delayed dispersal and association with kin could then offer adaptive benefits through an individual fitness gain. H

  • Tidskriftsartikel (refereegranskat)abstract
    • The evolutionary payoff accruing to parents from breeding offspring could be an incentive for prolonged investments in the offspring. Enhanced survival for offspring as a result of such a prolonged parental investment would increase the value of remaining

  • Tidskriftsartikel (refereegranskat)abstract
    • 1. Siberian jays (Perisoreus infaustus) can acquire breeding status along two routes. Some offspring dispersed in their first summer of life, but one-third of birds ringed as nestlings (39 of 117,40 broods) postponed dispersal beyond their first winter an

  • DNA-FINGERPRINTING SHOWS WITHIN-SEASON MULTIPLE PATERNITY IN THE ADDER (VIPERA-BERUS)

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Female adders (Vipera berus) have been observed to copulate several times per season with different males. Observations of matings may not truly reflect paternity because prolonged contractions of the female uterus may function as a ''copulatory plug.'' W

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • In the adder (Vipera berus) multiple inseminations during the spring mating season have been demonstrated. with fertilization taking place several weeks after mating activities have ceased. Subsequent sperm competition in the female reproductive tract can

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Fennoscandia probably constitutes one of the best places on earth to study faunal history. During the height of the most recent glacial period Fennoscandia was completely, covered with ice. Thus, the majority of extant species must originate from ancestor

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • The genetic structure of field vole (Microtus agrestis) populations from northern Europe was examined by restriction fragment length polymorphisms of mitochondrial DNA (mtDNA) in 150 individuals from 67 localities. A total of 83 haplotypes was observed, m

  • DIFFERENTIAL MALE GENETIC SUCCESS DETERMINES GENE FLOW IN AN EXPERIMENTALLY MANIPULATED MOUSE-POPULATION

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Sexual selection arises when genetically different males show heritable differences in reproductive success. Mouse mating behaviour involves both male competition and female choice. In this paper we show that introduced Y-linked DNA markers spread more ex

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Females of socially monogamous species may copulate with attractive non-mates to obtain access to the genes of such males, and a preference for attractive copulation partners may result in sexual selection. Extra-pair copulations are common in the sociall

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • We studied determinants of breeding dispersal (the distance that an animal shifts its mean home range co-ordinate between reproductive events) in an individually marked population of sand lizards (Lacerta agilis) in south west Sweden during 1987-1991. Fem

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • We investigated factors that may determine mate guarding tactics in male sand lizards. In a sample of lizards from a museum collection, larger males had larger testis, but in laboratory experiments and in a natural population larger males did not sire mor

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • The recent explosion of research on sperm competition, and the emerging idea that females may control paternity of their offspring via "sperm choice", raise many methodological questions. One central issue is the role of inbreeding-induced mortality of of

  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • The pied flycatcher (Ficedula hypoleuca) is sexually dichromatic with extreme variation in male plumage coloration. The benefit for males of having black plumage is controversial, and few studies have found evidence for a sexual selection benefit of being

    • If interspecific hybrids are fertile and backcross to either parental species, transmission of mitochondrial DNA over the species barrier can occur. To investigate if such transmission has occurred between the brown hare Lepus europeus Pall and the mounta
