Not just semantics: CO2 fertilization can be a disturbance leading to worldwide forest degradation

Plants, People, Planet
Societal Impact Statement The physiological effects of increased atmospheric CO2 (CO2 fertilization) on intact forests are generally seen as a process that might buffer them against the impacts of climate change. However, CO2 fertilization can also cause

Laser microdissection as a new approach to prefertilization genetic diagnosis [PDF]

, 2000
The genetic status of oocytes can be determined by polar body (PB) analysis. Following PB extraction, a genetic evaluation is performed. As each PB contains the complementary genetic material of the oocyte, PB analysis reveals information about its ...

Association between fertilin beta, protamines 1 and 2 and spermatid-specific linker histone H1-like protein mRNA levels, fertilization ability of human spermatozoa, and quality of preimplantation embryos.

Folia Histochemica et Cytobiologica, 2008
Fertilization involves a series of cellular interactions culminating in the fusion of gamete membranes, creating a zygote and then an embryo. During the process of human fertilization in vivo or in conventional in vitro fertilization (IVF), sperm must be
