Hatching Success of Lake Whitefish Eggs in Heated Water
The Progressive Fish-Culturist, 1980Abstract Eggs of lake whitefish (Coregonus clupeaformis) were first incubated at 0.5 to 8°C and then, for the last half of development, at 8 and 10°C. Provision of higher temperatures for the last half of the incubation period resulted in hatching success of more than 85% with less than 6% abnormal fry, in contrast to earlier studies that found 10°C ...

pH-related Hatching Success of Triops cancriformis (Crustacea: Branchiopoda: Notostraca)
Hydrobiologia, 2006Six different pH ranges were tested for the hatching rate of Triops cancriformis cysts. Cumulative hatching numbers approach to approximately 50% of cysts. The highest hatching rates, co-occurring with the shortest hatching times, were recorded in the neutral range. No hatching took place at pH values 9 and above.

Hypoxia Causes Transgenerational Impairment of Ovarian Development and Hatching Success in Fish
Environmental Science & Technology, 2019Hypoxia is a pressing environmental problem in both marine and freshwater ecosystems globally, and this problem will be further exacerbated by global warming in the coming decades. Recently, we reported that hypoxia can cause transgenerational impairment of sperm quality and quantity in fish (in F0, F1, and F2 generations) through DNA methylome ...

Hatching success of ostrich eggs in relation to setting, turning and angle of rotation
British Poultry Science, 20001. Three trials were designed to study the effects of axis of setting, turning frequency and axis and angle of rotation on the hatching success of ostrich eggs. The joint effects of axis of setting and angle of rotation were investigated in a fourth trial. 2.

Effect of Selection for Successful Reproduction on Hatching Synchrony and Asynchrony
The Auk, 1994-Hypotheses regarding the evolution of asynchronous hatching in birds are evaluated with respect to the Murray-Nolan clutch-size equation, which distinguishes between the number of broods successfully reared per female during a breeding season (2:1 Pi) and within-brood survivorship (which affects Z. Xx).

Increased hatching success as a direct benefit of polyandry in birds.
Evolution; international journal of organic evolution, 2015Multiple mating by females is difficult to explain in primarily socially monogamous taxa such as birds because mating outside the pair bond often provides no obvious benefit to females. Although indirect selection is often invoked to explain the evolution of polyandry, current evidence suggests that selection on indirect benefits of mating is weak ...
