摘要:
of facet size and number in a ~390-Myr-old local assemblage of the trilobite Eldredgeops rana, which has well-preserved compound eyes and a wide body
Data from: Age-graded dominance hierarchies and social tolerance in packs of free-ranging dogs

摘要:
It is believed that domestic dogs rarely form packs with age-graded hierarchical structures similar to those found in wolves. Dog-wolf comparisons
Data from: The size advantage model of sex allocation in the protandrous sex-changer Crepidula fornicata: role of the mating system, sperm storage

摘要:
Sequential hermaphroditism is adaptive when the reproductive value of an individual varies with size or age, and this relationship differs bet
Data from: Male-biased sex allocation in ageing parents; a longitudinal study in a long-lived seabird

senescence;sex allocation;Birds;Sterna hirundo
DOI:
doi:10.5061/dryad.tj247
摘要:
in common terns (Sterna hirundo), slightly sexually size-dimorphic seabirds. We decomposed parental age effects into within-individual change and sex allocation

摘要:
of offspring life-history milestones, parental age effects can also have a negative impact on offspring size, with offspring of older parents being smaller tha

摘要:
t of a brood size manipulation. Nestling TL was measured at 50 days after hatching, which allowed investigation of the influence of the age of both their biological and foster
Data from: Linkage disequilibrium and effective population size when generations overlap

摘要:
the influences of overlapping generations on estimates of effective size provided by the linkage disequilibrium method. Our simulations focus on two factors
