Body Size and Condition, Timing of Breeding, and Aspects of Egg Production in Eastern Kingbirds [PDF]

open access: yes, 1986
Variation in timing of breeding in Eastern Kingbirds (Tyrannus tyrannus) was correlated only weakly with external morphological characters, but was correlated positively and significantly with estimates of body size based on measurements of skeletons and

Variability of Thick Albumen in Fresh-Laid Eggs

open access: yesPoultry Science, 1934
Abstract GRADES of eggs are based, at least in part, on the interior quality, and every egg that grades below first grade represents an economic loss that increases as the grade lowers. These lower grades are in a large measure responsible for the wide difference in price paid by the consumer.

Do environmental fluctuations during development affect trait variation? An experimental test with salinity

open access: yesOikos, EarlyView.
Human‐induced climate change is a driver of extinction, with extreme events occurring more frequently. It increases both the amount and fluctuations in environmental stress that organisms experience. In such environments, greater intra‐specific trait variation creates more potential for adaptation through natural selection.

COMPARATIVE PRODUCTIVE PERFORMANCE AND EGG CHARACTERISTICS OF PULLETS AND SPENT LAYERS [PDF]

open access: yes, 2008
Production performance and egg quality characteristics of pullets and spent layers were compared in this study. Forty birds, each from the flocks of pullets (24 weeks old) and spent layers (76 weeks old) were selected as experimental birds.

Nanoparticle‐Based Tetracycline Delivery Systems: Advancing Therapeutic Effectiveness and Tackling Antibiotic Resistance

open access: yesParticle &Particle Systems Characterization, EarlyView.
This review explores improved tetracycline (TCN) delivery via polymer‐based nanocarriers to enhance solubility, stability, and targeted release. It also covers stimuli‐responsive systems, triggered by pH, enzymes, or reactive oxygen species (ROS), and co‐delivery approaches that increase therapeutic efficacy in cancer and inflammatory diseases ...
