Breeding for dependence, not cooperation, may have driven initial dog domestication.
Furthermore, the dependence of tritium breeding ratio (TBR) on volume ratios of water and breeder occupying a blanket, and the impact of D2O replacing H2O as a coolant on the K-DEMO blanket have also been investigated with the calculations on the basis of the Monte Carlo simulation MCNPX code.
For example, if a salmonid population experiences density dependence both during breeding and the juvenile stage, a reduction in the amount of breeding habitat will cause intensified competition during breeding but relaxed competition for juveniles (Einum et al. 2008).
We found that the interaction between delayed breeding, density-dependence, and demographic stochasticity accounts for 33 to 49% of the variance in population size.
The crescent honeyeater's dependence on long-term partnerships and breeding territories means that breeding success is threatened by the death of one partner or the destruction of habitual territory.
MRS occurence dependence on the kennel size (number of breeding bitches in kennel) was assessed using logistic regression analysis.
(a) A complex pattern of dependence of polymorphism stability on interaction among the breeding system, recombination rate, and the genetic architecture of the selected trait emerged.
Note that the dependence of B on n comes only through the number of breeding females in year n, not through R(n).
Density dependence in elephant seals has been shown to operate mainly during breeding where concentrated adult aggregations onshore can directly affect pup survival or the age at first reproduction [ 43, 44, 46, 60] even though the exact form and strength of density dependence acting in this species is still a matter of some debate [ 22, 47].
However, it is possible that any increase in breeding population may be masked by yearly shifts in breeding sites, and/or the action of density dependence during the breeding season [14], [28].
