Species Preservation

Preservation and Field Speciation of Inorganic Arsenic Species in Groundwater

This research describes the development of a dual preservationand field-speciation technique for As(III) and As(V) speciation of a sample preserved with ethylenediaminetetraacetic acid (EDTA) and acetic acid (HAc). The new method was compared with existing preservationand field-speciation methods and was shown to be accurate and precise in spite of possible interference from ferrous iron in the...

Preservation of species abundance in marine death assemblages.

Fossil assemblages of skeletal material are thought to differ from their source live communities, particularly in relative abundance of species, owing to potential bias from postmortem transport and time-averaging of multiple generations. However, statistical meta-analysis of 85 marine molluscan data sets indicates that, although sensitive to sieve mesh-size and environment, time-averaged death...

Biobanking and fertility preservation for rare and endangered species

For more than 25 years, systematic gathering and cryo-storage of biomaterials from diverse wild species have been ongoing to save gene diversity and improve captive (ex situ) and wild (in situ) animal management. Cryo-storage of biomaterials offers broad opportunities from helping understand the fundamental biology of unstudied species to enhanced conservation breeding, genomics and veterinary ...

I-26: Fertility Preservation

Infertility is a very disastrous side effect in young females, especially in traditional male-dominated societies. The aim of this talk is to discuss the possible ways for fertility preservation in both man and woman. Another aspect is to how to predict women at threat of premature ovarian failure. It will also illustrate the association of cytochrome P450 (CYP2C19) polymorphism with ovarian to...
