Iterated prisoner's dilemma in an asocial world dominated by loners, not by defectors [0.03%]

Cooperation among genetically unrelated individuals can arise when pairs of individuals interact repeatedly in the Prisoner's Dilemma. However, the conditions allowing the evolution of reciprocal cooperation become extremely restrictive as ...

Anisogamy refers to gametes that differ in size, and characterizes the difference between males and females. The evolution of aniosgamy is widely interpreted as involving conflict between gamete producers with small sperm parasitizing on th...
Nonlinearity in eigenvalue-perturbation curves of simulated population projection matrices [0.03%]
模拟种群投影矩阵本征值摄动曲线的非线性分析

Sensitivity and elasticity analyses of population projection matrices (PPMs) are established tools in the analysis of structured populations, but they make a linear approximation of the usually nonlinear relationship between population grow...
Faà di Bruno's formula and the distributions of random partitions in population genetics and physics [0.03%]

We show that the formula of Faà di Bruno for the derivative of a composite function gives, in special cases, the sampling distributions in population genetics that are due to Ewens and to Pitman. The composite function is the same in each ...

Different methods have been developed to consider the effects of statistical associations among genes that arise in population genetics models: kin selection models deal with associations among genes present in different interacting individ...
Population and prehistory I: Food-dependent population growth in constant environments [0.03%]
人口与旧石器时代中期人群扩张量化：稳定环境下的食物依赖型人口增长

We present a demographic model that describes the feedbacks between food supply, human mortality and fertility rates, and labor availability in expanding populations, where arable land area is not limiting. This model provides a quantitativ...
The co-evolution of culturally inherited altruistic helping and cultural transmission under random group formation [0.03%]
随机分组下文化传承与文化适应的共同进化模型

Limited migration results in kin selective pressure on helping behaviors under a wide range of ecological, demographic and life-history situations. However, such genetically determined altruistic helping can evolve only when migration is no...
Non-linear density dependence in time series is not evidence of non-logistic growth [0.03%]
时间序列中的非线性密度制约并非 logistic 增长的证据
C Patrick Doncaster
C Patrick Doncaster
Time series of population density are often used to seek deviations from logistic regulation by testing for a non-linear decline in per capita growth rate with density. Here I show that this method fails when the interval between observatio...
A novel fitness proxy in structured locally finite metapopulations with diploid genetics, with an application to dispersal evolution [0.03%]
具有二倍体遗传学的结构化有限元元种群的新颖适应度代理，以及在扩散进化中的应用

Many studies of evolutionarily stable strategies (ESS) for technical reasons make the simplification that reproduction is clonal. A post-hoc justification is that in the simplest eco-evolutionary models more realistic genetic assumptions, s...
Life-history constraints on the success of the many small eggs reproductive strategy [0.03%]
life-history制约下“产下大量小卵”繁殖策略的成功率
K H Andersen,J E Beyer,M Pedersen et al.
K H Andersen et al.
The reproductive strategy of most fishes is to produce a large number of tiny eggs, leading to a huge difference between egg size and asymptotic body size. The viability of this strategy is examined by calculating the life-time reproductive...
