On the Effects of Stress, Resistance to Stress, and Developmental Stability On Life History Characters In <em>Drosophila Melanogaster</em>
… rates, their gonadal development, and their developmental stability as measured by fluctuating asymmetry. The theoretical implications of this and other stresses and selection pressures that may be operating in <em>Drosophila melanogaster</em> and other taxa are discussed.</p>

Mapping the Dorsal Skin Pigmentation Patterns of Two Sympatric Populations of Ambystomatid Salamanders, <em>Ambystoma opacum</em> and <em>A. maculatum</em> from Northeast Tennessee.
… and how, iii) whether gender differences in developmental stability occur, and iv) the extent of phenotypic variation within each species. The findings of this study revealed SSD in both species of salamanders. The most parsimonious statistical model was developed that explained the influence …

Human skeletal asymmetry. A study of directional and fluctuating asymmetry in assessing health, environmental conditions, and social status in English populations from the 7th to the 19th centuries.
… analysis as it detects disruptions in the developmental stability of osseous structures attributed to environmental and biomechanical environments. The primary aim of this study is to establish a baseline for normal levels of asymmetry in English archaeological populations in order to …

LARVAL DEVELOPMENT AND MORPHOLOGY OF NORTH AMERICAN BURBOT (LOTA LOTA MACULOSA)
… growth patterns by the flexion stage indicating developmental stability by this time. Variability in larval burbot hatching, morphology, and developmental rates likely supports the persistence of this species throughout North America.</p>

Experimental studies on the reproductive biology of the Waterstrider, Gerris buenoi (Heteroptera: Gerridae)
… by a progressive decline in egg quality (developmental stability and hatching success), and increased reproductive rate advanced this decline. Therefore, senescence occurs in G. buenoi, and reproductive rate advances its onset. The mating behaviour of G. buenoi was studied with a series of …

Effects of embryonic exposure to androgen-active endocrine disrupting chemicals in Japanese quail
… Measures of reproduction, behavior, growth, and developmental stability were also taken in this study. Male and female rates to sexual maturity were altered by the one-time in ovo exposure to DDE and trenbolone. Male reproductive behavior, as measured by attempts to mount and successful cloacal …

Low Temperature Induction of Males and Other Developmental Anomalies in a Self-Fertilizing Hermaphroditic Fish Species
… this species, and it may be that low temperature developmental stress is not a general challenge to this species.

The Effects of Childhood Irritability on Adolescent Outcomes and Treatment Response in Children with Attention-Deficit/Hyperactivity Disorder
… adult outcomes; however, less is known about the stability of irritability from childhood through adolescence, particularly in individuals with ADHD, and which factors may moderate stability and outcomes. Neurodevelopmental models postulate that emotion dysregulation reflects underlying …

Bilateral Asymmetry in Chickens of Different Genetic backgrounds
… of a series of experiments conducted to study developmental stability of various genetic stocks at different stages in the life cycle. The primary measures of stability were type and degree of asymmetry of bilateral traits and heterosis. Higher relative asymmetry (RA), which was defined as …

Population genetic history of the British roe deer (Capreolus capreolus) and its implications for diversity and fitness
… (FA) of 10 skull traits as an indicator of developmental stability. Correlations of FA and genetic diversity indices were examined at the level of individuals within populations, across all populations and among populations. All correlations existed in expected directions; however, …
