Developmental Psychology, 2022 Guided by evolutionary-developmental models, this study tested the hypothesis that children's exposure to parental relationship instability, defined by initiation and dissolution of caregiver intimate relationships, has both costs in cognitive ...

Non‐visual cues and indirect strategies that enable discrimination of asymmetric mates
Ecology and Evolution, 2022 The postulates of developmental instability–sexual selection hypothesis is intensely debated among evolutionary biologists, wherein despite a large amount of empirical data, evidence for or against it has been largely inconclusive.

Skeletal age during hurricane impacts fluctuating asymmetry in Cayo Santiago rhesus macaques
Ecology and Evolution, 2023 As natural disasters become more frequent due to climate change, understanding the biological impact of these ecological catastrophes on wild populations becomes increasingly pertinent.

Asymmetry in the common wall lizard Podarcis muralis under different levels of urbanization: The effect of trait and FA index selection [PDF]
Archives of Biological Sciences, 2019 The use of fluctuating asymmetry (FA) as a measure of developmental instability and its relationship to stress and fitness is highly controversial. We examined whether the selection of different FA indices and traits influences the results of FA analysis.

Body Size and Symmetry Properties of Termite Soldiers Under Two Intraspecific Competition Scenarios
Frontiers in Ecology and Evolution, 2022 Single-piece nesting termites live and forage in the same piece of wood throughout their life, which limit their colony size. In certain species, more than one colony thrive in a given piece of wood (multicolonial substrate) and intraspecific competition

Genome-wide deficiency mapping of the regions responsible for temporal canalization of the developmental processes of Drosophila melanogaster [PDF]
, 2011 Developmental processes of organisms are programed to proceed in a finely regulated manner and finish within a certain period of time depending on the ambient environmental conditions.

GENETICS OF FLUCTUATING ASYMMETRY: A DEVELOPMENTAL MODEL OF DEVELOPMENTAL INSTABILITY [PDF]
Evolution, 1999 Although numerous studies have found that fluctuating asymmetry (FA) can have a heritable component, the genetic and developmental basis of FA is poorly understood. We used a developmental model of a trait, according to a diffusion-threshold process, whose parameters are under genetic control.

Hand preference and developmental instability [PDF]
Psychobiology, 1993 The origins of individual variation in hand preference are unclear, with some theories emphasizing environmental factors, and others, genetic factors. In two studies, we investigated the hypothesis that developmental instability, leading to imprecise expression of a near-universal neural design, underlies phenotypic variation in hand preference and ...

ATR is required to complete meiotic recombination in mice
Nature Communications, 2018 ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a hypomorphic Atr mutation and chemical inhibition, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and ...

Diversity, 2023 In this paper, we assess the environmental impact of urbanization in three freshwater biotopes, using the levels of fluctuating asymmetry (FA) in 10 meristic morphological traits in the Marsh Frog (Pelophylax ridibundus (Pallas, 1771)).
