The dangers of leaving home: dispersal and mortality in snakes
For animal populations in many parts of the world, direct (albeit often accidental) killing by humans may be a signi®cant source of mortality. Many snakes are killed by people (especially by automobiles) every year, but the determinants of a snake's vulnerability to anthropogenic mortality (and thus, patterns of mortality with respect to sex, age and season) are poorly known. We present data on...
متن کاملNot leaving home: grandmothers and male dispersal in a duolocal human society
Models suggest that dispersal patterns will influence age- and sex-dependent helping behavior in social species. Duolocal social systems (where neither sex disperses and mating is outside the group) are predicted to be associated with mothers favoring sons over daughters (because the latter are in reproductive competition with each other). Other models predict daughter-biased investment when be...
متن کاملFitness consequences of dispersal: is leaving home the best of a bad lot?
Using 20 years of demographic and genetic data from four populations of banner-tailed kangaroo rats (Dipodomys spectabilis), we asked whether dispersing individuals gain benefits during adulthood that might compensate for the substantial survival costs they experience as juveniles. Compared to philopatric animals, within- and between-population dispersers gained no measureable advantages in adu...
متن کاملTowards a small animal model for hepatitis C.
Hepatitis C virus (HCV) causes chronic liver disease and affects an estimated 3% of the world's population. Options for the prevention or therapy of HCV infection are limited; there is no vaccine and the nonspecific, interferon-based treatments now in use are frequently ineffective and have significant side effects. A small-animal model for HCV infection would significantly expedite antiviral c...
متن کاملSpatial Distances after Leaving Home
This research used geocoded data from 10 waves (2000 – 2009) of the German Socio-economic Panel Study to investigate the spatial distances of young adults’ initial move-outs (N = 1,986). Linear regression models predicted moving distances by factors at individual, family, household, and community level. Overall, home leavers moved across strikingly small distances with a median value of less th...
