Developmental stability: a major role for cyclin G in drosophila melanogaster. [PDF]

open access: yesPLoS Genetics, 2011
Morphological consistency in metazoans is remarkable given the pervasive occurrence of genetic variation, environmental effects, and developmental noise.

Scutation asymmetries in red-footed tortoise Chelonoidis carbonaria Spix, 1824 (Testudines: Testudinidae) [PDF]

open access: yesPapéis Avulsos de Zoologia, 2020
The ability of an individual to withstand random perturbations during its development is considered a good indicator of environmental and genetic stress. A common means of assessing developmental stability is through analysis of fluctuating asymmetry (FA)

A multifrequency instability of cavitating inducer systems [PDF]

open access: yes, 2006
Recent testing of high speed cavitating turbopump inducers has revealed the existance of more complex instabilities than the previously-recognized cavitating surge and rotating cavitation.

Asymmetry patterns are associated with body size and somatic robustness among adult !Kung San and Kavango people

open access: yesAnthropological Review, 2019
Asymmetry of bilateral anatomical structures is widely found in nature. Fluctuating asymmetry, i.e. mostly tiny random deviations from perfect symmetry in bilateral structures, is mainly interpreted within the framework of developmental instability. This

A single basis for developmental buffering of Drosophila wing shape.

open access: yesPLoS ONE, 2006
The nature of developmental buffering processes has been debated extensively, based on both theoretical reasoning and empirical studies. In particular, controversy has focused on the question of whether distinct processes are responsible for canalization,

Fluctuating Asymmetry in Morphological Characters of the Invasive Round Goby Neogobius melanostomus Populations from Different Habitats of the Sava River Basin, Croatia

open access: yesCroatian Journal of Fisheries, 2023
Round goby Neogobius melanostomus is one of the three invasive Ponto-Caspian gobies found in the Sava River basin in Croatia. It has a negative effect on the native ecosystems and is more abundant in highly polluted areas. The objective of this study was

BIOMONITORING OF ECOLOGICAL STATE OF THE ENVIRONMENT IN THE ZONE OF INFLUENCE OF THE “CHERVONOGRADSKA” MINE OF THE LVIV-VOLYN COALFIELD [PDF]

open access: yes, 1999
Coal mining has a very negative impact on the environment and it requires monitoring studies to assess the degree of environmental ...

Fluctuations of tilapia asymmetry (Oreochromis niloticus) at Marine Mandiri Fisheries Training Center (P2MKP) Water World, Banyuwangi

open access: yesJournal of Aquaculture Science, 2017
Fluctuating asymmetry of the bilateral meristic characteristic is one of the simple methods that can be used to determine the stability of an individual fish development. This study aims to provide quantitative information about the level of asymmetry of

Fluctuating asymmetry and psychometric intelligence

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1997
Little is known about the genetic nature of human psychometric intelligence (IQ), but it is widely assumed that IQ's heritability is at loci for intelligence per se. We present evidence consistent with a hypothesis that interindividual IQ differences are partly due to heritable vulnerabilities to environmental sources of developmental stress, an ...

Facial symmetry is positively associated with self-reported extraversion [PDF]

open access: yes, 2007
Fink et al. (2005) reported significant associations between facial symmetry and scores on some of the “big five” personality dimensions derived from self-report data.
