Asexual reproduction changes predator population dynamics in a life predator-prey system [0.03%]
无性繁殖改变了生命捕食者-猎物系统中的猎物种群动态属性

Many organisms display oscillations in population size. Theory predicts that these fluctuations can be generated by predator-prey interactions, and empirical studies using life model systems, such as a rotifer-algae community consisting of ...
Variance in animal longevity: contributions of heterogeneity and stochasticity [0.03%]
动物寿命变异性的贡献：异质性和随机性的影响

Variance in longevity among individuals may arise as an effect of heterogeneity (differences in mortality rates experienced at the same age or stage) or as an effect of individual stochasticity (the outcome of random demographic events duri...
Mating, births, and transitions: a flexible two-sex matrix model for evolutionary demography [0.03%]
兼具生育和择偶的两性进化矩阵模型

Models of sexually-reproducing populations that consider only a single sex cannot capture the effects of sex-specific demographic differences and mate availability. We present a new framework for two-sex demographic models that implements a...
The relationship of mammal survivorship and body mass modeled by metabolic and vitality theories [0.03%]
代谢和活力理论框架下的哺乳动物存活率与体重关系研究
James J Anderson
James J Anderson
A model describes the relationship between mammal body mass and survivorship by combining replicative senescence theory postulating a cellular basis of aging, metabolic theory relating metabolism to body mass, and vitality theory relating s...
Inferring transient dynamics of human populations from matrix non-normality [0.03%]
利用矩阵非正态性推断人类人口的瞬态动态

Alex Nicol-Harper et al.
In our increasingly unstable and unpredictable world, population dynamics rarely settle uniformly to long-term behaviour. However, projecting period-by-period through the preceding fluctuations is more data-intensive and analytically involv...
