When will evolution lead to deceptive signaling in the Sir Philip Sidney game? [0.03%]
进化论视角下菲利普·锡德尼游戏产生欺骗信号的条件分析
Steven Hamblin,Peter L Hurd
Steven Hamblin
Sir Philip Sidney games are a widely used model of simple signaling. Johnstone and Grafen [Johnstone, R.A., Grafen, A., 1993. Dishonesty and the handicap principle. Animal Behaviour 46, 759-764] present a version in which the Evolutionarily...
Fixation probability with multiple alleles and projected average allelic effect on selection [0.03%]
多重等位基因下的固定概率及对选择的平均等位基因效应预测
Sabin Lessard,Philippe Lahaie
Sabin Lessard
The first-order effect of selection on the probability of fixation of an allele, with respect to an intensity of selection s>0 in a diploid population of fixed finite size N, undergoing discrete, non-overlapping generations, is shown to be ...
The genealogy, site frequency spectrum and ages of two nested mutant alleles [0.03%]
两个嵌套突变等位基因的系谱、位置频率光谱及年龄分布研究
Asger Hobolth,Carsten Wiuf
Asger Hobolth
In this paper we consider the genealogy of two nested mutant alleles, assuming the constant-size neutral coalescent model with infinite sites mutation. We study the conditional genealogy and derive explicit formulas for the joint and margin...
Biological diversity: distinct distributions can lead to the maximization of Rao's quadratic entropy [0.03%]
生物学多样性:不同的分布可以最大化Rao二次熵
Sandrine Pavoine,Michael B Bonsall
Sandrine Pavoine
Rao's quadratic entropy (QE) is a diversity index that includes the abundances of categories (e.g. alleles, species) and distances between them. Here we show that, once the distances between categories are fixed, QE can be maximized with a ...
Effects of epistasis and the evolution of genetic architecture: exact results for a 2-locus model [0.03%]
上位性对遗传结构进化的影响:一个两基因模型的确切结果
José M Alvarez-Castro,Michael Kopp,Joachim Hermisson
José M Alvarez-Castro
We study a two-locus model of a quantitative trait with a continuum-of alleles and multilinear epistasis that evolves under mutation, selection, and genetic drift. We derive analytical results based on the so-called House of Gauss approxima...
On parameter estimation in population models II: multi-dimensional processes and transient dynamics [0.03%]
人口模型中的参数估计(二):多维过程和瞬态动态

J V Ross
Recently, a computationally-efficient method was presented for calibrating a wide-class of Markov processes from discrete-sampled abundance data. The method was illustrated with respect to one-dimensional processes and required the assumpti...

In this paper, we study the evolution of the per capita rate of reproduction as a function of time in the modelling framework introduced by Eskola and Geritz [Eskola, H.T.M., Geritz, S.A.H., 2007. On the mechanistic derivation of various di...

In this paper a spatially implicit neutral model for explaining the edge effects between habitats is proposed. To analyze this model we use two different approaches: a discrete approach that is based on the Master equation for a one step ju...
The coevolution of two phytoplankton species on a single resource: allelopathy as a pseudo-mixotrophy [0.03%]
单资源下两个浮游植物物种的协同进化:化学抑制作为准混合营养作用

Without the top-down effects and the external/physical forcing, a stable coexistence of two phytoplankton species under a single resource is impossible - a result well known from the principle of competitive exclusion. Here I demonstrate by...
Parameterizing the growth-decline boundary for uncertain population projection models [0.03%]
不确定人口预测模型下的增长式微边界参数化问题研究
Joan Lubben,Derek Boeckner,Richard Rebarber et al.
Joan Lubben et al.
We consider discrete time linear population models of the form n(t+1)=An(t) where A is a population projection matrix or integral projection operator, and n(t) represents a structured population at time t. It is well known that the asymptot...
