Data from: Can't live with them, can't live without them? Balancing mating and competition in two-sex populations

摘要:
, and population growth. However, in two-sex populations, mating and recruitment should also be affected by density and by its interactions with sex ratio. Density may hav
Data from: Population structure leads to male-biased population sex ratios under environmental sex determination

摘要:

Data from: Daphnia females adjust sex allocation in response to current sex ratio and density

DOI:
doi:10.5061/dryad.sb269
摘要:
, and made repeated observations of natural populations over their growing season, to disentangle effects of population density and the timing of sex from
Data from: Is biasing offspring sex ratio adaptive? a test of Fisher’s principle across multiple generations of a wild mammal
负责人:
关键词:
frequency-dependent selection;North American red squirrel;Fisher\u2019s principle;Sex ratio;Tamiasciurus hudsonicus
DOI:
doi:10.5061/dryad.347tv64
摘要:
Fisher’s principle explains that population sex ratio in sexually reproducing organisms is maintained at 1:1 due to
Data from: Between-year variation in population sex ratio increases with complexity of the breeding system in Hymenoptera
负责人:

Evolution: social;Behavior: social;Kin: selection;Sex: ratio;Behavior: evolution;Hymenoptera;Ecology: behavioral
DOI:
doi:10.5061/dryad.8590
摘要:
to increased between-year variation in population sex ratio, we conducted a comparative analysis across 47 Hymenoptera species differing in their breeding system
Data from: Sex-chromosome differentiation and ‘sex races’ in the common frog (Rana temporaria)
负责人:

Gonadal development;XY recombination;sex chromosomes;epigenetic sex determination;Rana temporaria;Sex ratio
DOI:
doi:10.5061/dryad.4j169
摘要:
from differences in sex-determination mechanisms rather than in XY-recombination patterns. Offspring from the northern population display equal
Data from: Sex-specific arrival times on the breeding grounds: hybridizing migratory skuas provide empirical support for the role of sex ratios

migration arrival dates population sex ratio sex-role reversal spring migration
DOI:
doi:10.5061/dryad.6v5g3
摘要:
, sex differences in timing of arrival should be driven by the operational sex ratio, shifting toward protogyny in female-biased populations. However, empirical
Data from: Effective population size in eusocial Hymenoptera with worker-produced males
负责人:
关键词:
effective population size;worker-produced males;Hymenoptera
DOI:
doi:10.5061/dryad.7p838r83
摘要:
In many eusocial Hymenoptera, a proportion of males are produced by workers. To assess the effect of male production by workers on the effective population size
Data from: Exploring the causes of small effective population sizes in cyst nematodes using artificial Globodera pallida populations
负责人:
关键词:
Globodera pallida;genetic drift;plant resistance;selection;nematode;effective population size
DOI:
doi:10.5061/dryad.7t3j55p
摘要:
. The balance between selection and genetic drift depends on the effective population size (Ne), rather than the real numbers of individuals in the population
Data from: Covariance of paternity and sex with laying order explains male bias in extra-pair offspring in a wild bird population
负责人:
关键词:
Mating Strategies;sexual selection;Cyanistes caeruleus;polyandry;sex allocation;Birds
DOI:
doi:10.5061/dryad.b6428
摘要:
ween offspring sex ratio and laying order is not consistent between years and populations in this species. Hence, we caution against treating the decline in proportion
