At all sampling times fertilization increased biofilm cover and reduced bare rock, while exclusion of grazers also enhanced biofilm.
He held great concern for detail and philological accuracy in identification, use and cultivation of different types of medicinal herbs, such as in which months medicinal plants should be gathered, their exact ripening times, which parts should be used for therapy; for domesticated herbs he wrote about planting times, fertilization, and other matters of horticulture.
Despite progesterone concentrations clearly above 47.7 nmol/L, as described by Concannon et al. (1975) [ 27] at the time of fertilization, signs of fertilization were missing probably due to a delay observed by Reynaud et al. (2005) [ 16] at least up to 83 hours after ovulation resulting in fertilization the earliest 90 hours after ovulation.
Time since fertilization began (years of experimental fertilization) did not influence tree mortality.
There is growing human evidence that paternal environmental factors around the time of fertilization play a role after fertilization.
An undetectable level of expression was noted in embryos at the time of fertilization [0 hours post-fertilization (hpf)], but detectable levels of mRNA transcripts were noted at 6 hpf, with a significant further increase by 1 dpf.
Another thing, we have since 1990 this Embryo Protection Law, which says that eggs are human beings from the time of fertilization.
The sex of a child is determined at the time of fertilization of the ovum by the spermatozoon.
This contradicts the basic claim that there is a human person present from the time of fertilization through the birth of the baby.
For a short time after fertilization, the conceptus, a minute bubblelike structure called a blastocyst, lies unattached in the uterine cavity.
At the time of fertilization the egg contains the components required to carry out protein synthesis, and hence development, through an early embryonic stage called the blastula.
