Bottom-up derivation of discrete-time population models with the Allee effect [0.03%]
具有Allee效应的离散时间种群模型的自下而上推导法

Masahiro Anazawa
This paper presents a framework in which various single-species discrete-time population models exhibiting the Allee effect are derived from first principles. Here, the Allee effect means a reduction in individual fitness at low population ...
Detecting hybrid speciation in the presence of incomplete lineage sorting using gene tree incongruence: a model [0.03%]
利用基因树不一致检测杂交物种形成（考虑未完成的谱系分离）的一种模型

Chen Meng
The application of phylogenetic inference methods, to data for a set of independent genes sampled randomly throughout the genome, often results in substantial incongruence in the single-gene phylogenetic estimates. Among the processes known...

Longevity is a life-history trait that is shaped by natural selection. Evolution will shape mortality trajectories and lifespans, but until now the evolutionary analysis of longevity is based principally on a density-independent (Euler-Lotk...
Effects of treatment and drug resistance on the transmission dynamics of malaria in endemic areas [0.03%]
治疗与抗药性对疟疾病传播动力学的影响研究

Christinah Chiyaka
We present a mathematical model for malaria treatment and spread of drug resistance in an endemic population. The model considers treated humans that remain infectious for some time and partially immune humans who are also infectious to mos...
An exact steady state solution of Fisher's geometric model and other models [0.03%]
费希尔几何模型及其他模型的精确稳态解

Because nearly neutral substitutions are thought to contribute substantially to molecular evolution, and much of our insight about the workings of nearly neutral evolution relies on theory, solvable models of this process are of particular ...
The role of epistasis on the evolution of recombination in host-parasite coevolution [0.03%]
上位性在宿主-寄生关系协同进化中对重组表型进化的作用机制研究
Roger D Kouyos,Marcel Salathé,Sarah P Otto et al.
Roger D Kouyos et al.
Antagonistic coevolution between hosts and parasites is known to affect selection on recombination in hosts. The Red Queen Hypothesis (RQH) posits that genetic shuffling is beneficial for hosts because it quickly creates resistant genotypes...
Evolution of learning in subdivided populations that occupy environmentally heterogeneous sites [0.03%]
占据环境异质性位点的隔离种群中的学习进化动力学
Kenichi Aoki,Wataru Nakahashi
Kenichi Aoki
We study the effects of natural selection and migration on the numbers of individual learners and social learners in subdivided populations that occupy environmentally heterogeneous sites. The island model and the circular stepping model ea...
Vegetation pattern shift as a result of rising atmospheric CO2 in arid ecosystems [0.03%]
大气CO₂浓度升高引起的干旱生态系统植被格局变化
Sonia Kefi,Max Rietkerk,Gabriel G Katul
Sonia Kefi
Arid ecosystems are expected to be among the ecosystems most sensitive to climate change. Here, we explore via model calculations how regular vegetation patterns, widely observed in arid ecosystems, respond to projected climatic shifts as p...
A network approach to modeling population aggregation and genetic control of pest insects [0.03%]
基于网络的害虫种群聚集及基因控制模型研究
Laith Yakob,Istvan Z Kiss,Michael B Bonsall
Laith Yakob
Historically, models of the invasion and biological control of insect pests have omitted heterogeneities in the spatial structure of the targeted populations. In this study, we use stochastic network simulations to examine explicitly popula...
Equilibrium between the "genuine mutualists" and "symbiotic cheaters" in the bacterial population co-evolving with plants in a facultative symbiosis [0.03%]
专性互惠者和共生欺骗者的平衡：植物-细菌可选择性共生系统中共进化模型分析
Nikolai A Provorov,Nikolai I Vorobyov
Nikolai A Provorov
The mathematical model for evolution of the plant-microbe facultative mutualistic interactions based on the partners' symbiotic feedbacks is constructed. Using the example of rhizobia-legume symbiosis, we addressed these feedbacks in terms ...
