Restricted maximum likelihood estimation of genetic parameters for egg production traits in relation to juvenile body weight in broiler chickens.
Models to estimate maternal genetic effects for juvenile body weight in broiler chickens.
Plasticity of juvenile body length, juvenile body depth, and juvenile tailspine length were calculated as the absolute difference in clone mean values in the presence and absence of the extract.
For juvenile body length, variation was found among treatments and for the treatment-clone (G x E) interaction.
We controlled for these confounding effects by calculating average within-clone correlations between life-history traits and juvenile body length, juvenile body depth, or juvenile tailspine length (Table 3).
For each treatment, the average within-clone correlations of life history traits with juvenile body length, juvenile body depth, or juvenile tailspine length are shown.
pulicaria was characterized by low levels of juvenile body lipid, adult fecundity, and population birth rates (Figs.
Daphnia galeata mandate had higher adult fecundity (P [is less than] 0.003) and juvenile body lipid (P [is less than] 0.003) than D.
pulicaria population growth rates was associated with variation in juvenile body lipid.
Our objective was to examine the food habits of juvenile walleye pollock for evidence of an annual cycle and to elucidate how these food habits may vary regionally in relation to previously observed geographic variation in juvenile body
condition and growth rate.
The episphere continues to recede, and the dorsal levators contract and pull the apical organ toward the esophagus until it becomes attached to the juvenile body
First, do molluscs have a larval body that is qualitatively distinct from the juvenile body? Second, what was the original molluscan life history?
The term "larval body" may imply something much more than a stage of development with transitory structures, particularly when it is contrasted with a "juvenile body" or "adult body." A potential implication is that most if not all structural components of the larval stage of ontogeny are transitory and ultimately replaced by structures of the juvenile/adult body.
These structures might be relics of an ancient larval body that was distinct from the juvenile body, or they might be caenogenetic structures of the larval stage.
Data on molluscan embryogenesis and cell lineage suggest that the trochophore-like stage of molluscs is little more than a ciliated gastrula when it first forms and the juvenile body differentiates from this as development progresses through the veliger stage.
