The integration of stable isotopes and dental microwear data allows diet to be directly assessed, the first large-scale dietary analysis of Homotherium (of any species) from the most prolific fossil site (Friesenhahn Cave, Texas) in the world for this species. While H. serum was thought to...
The male must therefore not be too large in relation to the most important prey. For these reasons, he should be smaller than the female. Among predatory birds, size dimorphism increases with the proportion of birds in the diet, which may be explained as follows. Adult birds have mainly ...
To avoid growth deficiencies during sclerotization, insect larvae thus need to obtain phenylalanine through their diet, to ensure they can produce tyrosine, dihydroxyphenylalanine (DOPA) and dopamine that are crucial for melanization immune responses and cuticular sclerotization46. It is interesting, ...

This study examined whether supplementing the diet with a commercial supplement containingzinc magnesium aspartate (ZMA) during training affects zinc and magnesium status, anabolic and catabolic hormone profiles, and/or training adaptations. Forty-two resistance trained males (27卤9 yrs; 178卤8 cm, ...
The specific activity of the MFOs rises more sharply on leaves of a highly preferred type-1 plant, the pin oak, than on an artificial wheat germ diet; the increase from mid-second instar to mid-fifth is 4.5- and 1.8-fold, respectively. The relationship of food consumption rate to ...

For fetal hypothalamic mRNA expression of 5α-reductase type 1, there was a main effect (P<0.02) of melatonin (expression relative to 18S rRNA: 1.55±0.19 for melatonin-treated vs. 0.78±0.22 for untreated) but no effect of dietary intake and no melatonin-diet interaction. There was no ...
A wide range of diet and habitat flexibility of these species may play a key role in their increase in abundance following a disturbance event. For instance, the Light-vented Bulbul was historically distributed to south of the Yangtze River, but has recently exhibited a strong northward expansion...
