What Makes It Difficult to Start an Intimate Relationship: A Taxonomy of the Reasons

open access: yesEurope's Journal of Psychology, 2021
Within the context of an evolutionary theoretical framework, the current research attempted to study the reasons that cause difficulties in starting an intimate relationship in the Greek cultural context. In particular, using qualitative research methods

Singing silver‐haired bats (Lasionycteris noctivagans)

open access: yesWildlife Society Bulletin, 2023
Characterizing sounds produced by animals can lead to better understanding of their behavioral ecology and conservation. While considerable focus has been on signals used by bats for echolocation, there has been less emphasis on nonecholocation sounds ...

Mate value, intrasexual competition and sociosexual desire drive Brazilian women's well-being

open access: yesEvolutionary Human Sciences, 2021
Well-being (vs. ill-being) might function as an internal guide for approaching (vs. avoiding) situations, strategies, and achievements that ancestrally led to higher (vs. lower) reproductive success.

Random Mating With a Finite Number of Matings [PDF]

open access: yesGenetics, 2003
Abstract Random mating is the null model central to population genetics. One assumption behind random mating is that individuals mate an infinite number of times. This is obviously unrealistic. Here we show that when each female mates a finite number of times, the effective size of the population is substantially decreased.

The evolution of mate choice and mating biases [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2003
We review the current status of three well-established models (direct benefits, indirect benefits and sensory drive) and one newcomer (antagonistic chase-away) of the evolution of mate choice and the biases that are expressed during choice. We highlight the differences and commonalities in the underlying genetics and evolutionary dynamics of these ...

Stress conditions promote Leishmania hybridization in vitro marked by expression of the ancestral gamete fusogen HAP2 as revealed by single-cell RNA-seq

open access: yeseLife, 2022
Leishmania are protozoan parasites transmitted by the bite of sand fly vectors producing a wide spectrum of diseases in their mammalian hosts. These diverse clinical outcomes are directly associated with parasite strain and species diversity.

Behavioral and Evolutionary Perspectives on Visual Lateralization in Mating Birds: A Short Systematic Review

open access: yesFrontiers in Physiology, 2022
The division of cognitive processing between the two hemispheres of the brain causes lateralized eye use in various behavioral contexts. Generally, visual lateralization is shared among vertebrates to a greater extent, with little interspecific variation.
