Zinc Requirements of Japanese Quails (Coturnix coturnix japonica) by Assessing Dose- Evaluating Response of Zinc Oxide Nano-Particle Supplementation [PDF]
Poultry Science Journal, 2017 This study was conducted to determine the effects of various doses and particle sizes (micro or nano) of dietary zinc and zinc oxide on growth performance, serum enzyme activities, carcass characteristics, and zinc requirements in Japanese quails.

Integrative Zoology, EarlyView.Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Silent Spring - the lost call [PDF]
, 2008 The "silence" in Rachel Carson's Silent Spring1 alludes to the demise of bird populations through reproductive problems and death resulting from exposure to the pesticides of that time, many of which are endocrine active.

Aflatoxicosis in the Laying Japanese Quail (Coturnix Coturnix Japonica)
Poultry Science, 1973 Abstract Dietary aflatoxins fed to 72 day old laying Japanese quail for six weeks at low levels of 2, 4, or 6 μg./gm. of feed caused malperformances. There were changes in feed conversion, egg production, egg weight, hatchability, and exterior and interior quality of the eggs.

Ethology, EarlyView.Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Postcopulatory sexual selection favors fertilization success of restocking hybrid quails over native Common quails (Coturnix coturnix) [PDF]
, 2015 Postcopulatory sexual selection plays an important role in the reproductive success of males in many species. Differences in fertilization success could affect rates of admixture and genetic introgression between divergent lineages. We investigated sperm

Divergent Selection for Egg Production in Coturnix coturnix japonica
Poultry Science, 1983 From a randombred control population of Coturnix coturnix japonica, strains were divergently selected for high (HE) and low (LE) 120-day egg production based on individual egg records. Based on five generations of selection, realized heritabilities for HE and LE were .063 +/- .055 and .353 +/- .020, respectively.
