Coevolution fails to maintain genetic variation in a host-parasite model with constant finite population size [0.03%]
寄主-寄生关系协同进化无法维持恒定有限群体大小的遗传多样性

Coevolutionary negative frequency-dependent selection has been hypothesized to maintain genetic variation in host and parasites. Despite the extensive literature pertaining to host-parasite coevolution, the temporal dynamics of genetic vari...
Computing the probability of gene trees concordant with the species tree in the multispecies coalescent [0.03%]
计算多物种谱系共祖模型中与物种树一致的基因树的概率

The multispecies coalescent process models the genealogical relationships of genes sampled from several species, enabling useful predictions about phenomena such as the discordance between a gene tree and the species phylogeny due to incomp...
Kleptoparasitic interactions modeling varying owner and intruder hunger awareness [0.03%]
考虑掠夺者和受害者的饥饿感的 kleptoparasitic 模型研究
Noble Chowdhury,Kirubel Kentiba,Yashwant Mirajkar et al.
Noble Chowdhury et al.
We consider a game theoretical model of kleptoparasitic interaction between two individuals, the Owner and the Intruder. The Owner is in possession of a resource and must decide whether to defend the resource against the Intruder or flee. I...
A heuristic model of the effects of phenotypic robustness in adaptive evolution [0.03%]
表型稳健性在适应进化中的作用的启发式模型
Emanuele Rigato,Giuseppe Fusco
Emanuele Rigato
A recent theoretical, deterministic model of the effects of phenotypic robustness on adaptive evolutionary dynamics showed that a certain level of phenotypic robustness (critical robustness) is a required condition for adaptation to occur a...
Loss of genetic variation in the two-locus multiallelic haploid model [0.03%]
两基因位点多重等位基因假二倍体模型中的遗传变异的丧失

Martin Pontz
In the evolutionary biology literature, it is generally assumed that for deterministic frequency-independent haploid selection models, no polymorphic equilibrium can be stable in the absence of variation-generating mechanisms such as mutati...

Cooperation significantly impacts a species' population dynamics as individuals choose others to associate with based upon fitness opportunities. Models of these dynamics typically assume that individuals can freely move between groups. Suc...
Evolution of transmission modifiers under frequency-dependent selection and transmission in constant or fluctuating environments [0.03%]
在恒定或波动的环境中，在频率依赖性选择和传播下的传播修饰因子的进化

Although the Reduction Principle for rates of mutation, migration, and recombination has been proved for large populations under constant selection, the fate of modifiers of these evolutionary forces under frequency-dependent or fluctuating...
The effects of diploid male production on honey bee colony evolution and survival [0.03%]
二倍体雄蜂的产生对西方蜜蜂群体进化和生存的影响

The order Hymenoptera includes most of the eusocial species on the planet. Correlated is the fact that many of the social species within the order are haplodiploid and use complementary sex determination (CSD) to determine the sex of offspr...
The spatial Muller's ratchet: Surfing of deleterious mutations during range expansion [0.03%]
空间穆勒棘轮效应：范围扩张期间的有害突变漂移

Félix Foutel-Rodier
During a range expansion, deleterious mutations can "surf" on the colonization front. The resultant decrease in fitness is known as expansion load. An Allee effect is known to reduce the loss of genetic diversity of expanding populations, b...

Resistance to insecticide is considered nowadays one of the major threats to insect control, as its occurrence reduces drastically the efficiency of chemical control campaigns, and may also perturb the application of other control methods, ...
