Assortative mating among Lake Malawi cichlid fish populations is not simply predictable from male nuptial colour

open access: yesBMC Evolutionary Biology, 2009
Background Research on the evolution of reproductive isolation in African cichlid fishes has largely focussed on the role of male colours and female mate choice. Here, we tested predictions from the hypothesis that allopatric divergence in male colour is

Size-assortative mating in the absence of mate choice [PDF]

open access: yes, 2009
Size-assortative mating is one of the most common mating patterns in nature. Nevertheless, the underlying behavioural mechanisms have received little attention.

Educational and age assortative mating in China: The importance of marriage order

open access: yesDemographic Research, 2019
Background: Family change in China is characterized by increasing divorce rates and a growing number of remarriages, like in many Western countries. Assortative mating is a crucial part of the institution of (re)marriage and plays a key role in the (re ...

Experimentally testing mate preference in an avian system with unidirectional bill color introgression

open access: yesEcology and Evolution, 2023
Mating behavior can play a key role in speciation by inhibiting or facilitating gene flow between closely related taxa. Hybrid zones facilitate a direct examination of mating behavior and the traits involved in establishing species barriers.

Evolution of assortative mating in a population expressing dominance [PDF]

open access: yes, 2011
In this article, we study the influence of dominance on the evolution of assortative mating. We perform a population-genetic analysis of a two-locus two-allele model.

Social Structure and Personality Assortment Among Married Couples [PDF]

open access: yes, 2006
We study the influence of social structure on assortative mating for personality in a large national sample (n=3616) of married and cohabitating couples in the Netherlands.

A life history perspective on strategic mating effort in male scorpionflies [PDF]

open access: yes, 2002
Engqvist L, Sauer KP. A life history perspective on strategic mating effort in male scorpionflies. Behavioral Ecology. 2002;13(5):632-636.In species with high male mating effort, there is a trade-off between mating effort spent in a current mating and ...

Educational constraints on marital sorting and income mobility.

open access: yesPLoS ONE
This paper examines the effect of educational assortative mating on overall income mobility in terms of both inter- and intragenerational mobility. In recent years, educational assortative mating has become a trend in China, and this marital sorting ...

Mate Choice Drives Evolutionary Stability in a Hybrid Complex. [PDF]

open access: yesPLoS ONE, 2015
Previous studies have shown that assortative mating acts as a driver of speciation by countering hybridization between two populations of the same species (pre-zygotic isolation) or through mate choice among the hybrids (hybrid speciation).

Assortative mating between European corn borer pheromone races: beyond assortative meeting. [PDF]

open access: yesPLoS ONE, 2007
BACKGROUND: Sex pheromone communication systems may be a major force driving moth speciation by causing behavioral reproductive isolation via assortative meeting of conspecific individuals. The 'E' and 'Z' pheromone races of the European corn borer (ECB)
