Patient discussion about precocial

Q. every time my friend eat, before she swallow it she gets severe heartburns and nausea. what causes this

A. She could be suffering from gastric acid problems and should try taking anti-acid medications (after consulting a doctor, of course). Also there's a simple test that can be done for a bacteria called H.pylori that makes the stomach produce more acid, and by taking antibiotics this problem resolves.

The epigenetic processes that act in domestication also modify the life histories of the fishes, allowing survival of both altricial and precocial forms (Balon, 1990, 2004a,b).
Emus and other precocial birds have joints similar to those of Horner's dinosaurs, yet these birds can walk just after emerging from the egg.
In precocial birds and crocodiles, however, hatchlings have pelvises already formed into bone.
Proposed explanations for intraspecific brood parasitism in precocial species and colonial nesters are not regularly applicable to territorial passerines (reviewed by Yom-Tov 2001).
Elevated testosterone levels are also characteristic of the period surrounding hatching in several precocial species, including Japanese Quail (Ottinger and Bakst 1981, Schumacher et al.
However, there are limited data on development of the stress response in precocial species that match studies tracking development of the stressresponse system in altricial species.
Is there a trade-off between egg size and clutch size in altricial and precocial nonpasserines?
Precocial birds may benefit more than altricial species from settlement decisions based on habitat conditions at time of territory establishment, rather than on a forecast of future conditions, because they can move their broods to high-quality foraging habitat soon after hatch (Kosztolanyi et al.
by precocial development), it is easy to see how uniparental care may suffice across a broader array of taxa.
Survival rates of ground nests of precocial birds might be expected to vary seasonally if vegetative cover changes, poorly concealed nests are selectively destroyed, or predator activity is affected by nest densities and availability of alternative prey (Klett and Johnson 1982, Dinsmore et al.
Conspecific brood parasitism (CBP) has been reported in 236 species (Yom-Tov 1980, 2001) and tends to be most common in precocial species such as waterfowl, colonial species, and species with specialized nest sites such as cavities (Yom-Tov 1980, 2001; Rohwer and Freeman 1989).
