Female Starlings With Experimentally Impaired Pre‐Laying Condition Produce Smaller But Vitamin A Richer Eggs

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We experimentally impaired the pre‐laying condition of female starlings by clipping two flight feathers per wing at the beginning of the breeding season, before egg laying. Impaired females laid the same number of eggs as control females, but smaller, and with higher levels of yolk vitamin A.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of
