Advancing ecological understandings through technological transformations in noninvasive genetics.
Albano Beja-Pereira,Rita Oliveira,Paulo C. Alves,Michael K. Schwartz,Gordon Luikart,Gordon Luikart +5 more
TL;DR: It is shown that many advances come from the fields of forensics, human health and domestic animal health science, and it is suggested that molecular ecologists explore literature from these fields, to continually increase the power and role of noninvasive genetics in molecular ecology and conservation genetics.

Fundamentals of Forensic DNA Typing
TL;DR: The basic principles of Forensic DNA Typing and its applications in medicine, science and research are studied.

Forensic trace DNA: a review
TL;DR: Although several methodological changes have facilitated profiling from trace samples in recent years it is also clear that many opportunities exist for further improvements.

TL;DR: Recognition of DNA activity associated expertise to be distinct from expertise associated with the identification of individuals is advocated, to be supported by dedicated training, competency testing, authorisation, and regular fit for purpose proficiency testing.

Overcoming Inhibition in Real-Time Diagnostic PCR
Johannes Hedman,Peter Rådström +1 more
TL;DR: The concept of integrating sampling, sample treatment, and the chemistry of PCR, i.e., pre-PCR processing, will be addressed as a general approach to overcoming real-time PCR inhibition and producing samples optimal for PCR analysis.

Journal ArticleDOI
DNA fingerprints from fingerprints
TL;DR: It is shown that an individual's genetic profile can now also be generated from swabs taken from objects touched by hands, providing a new tool for crime scene investigations.
Journal ArticleDOI
The propensity of individuals to deposit DNA and secondary transfer of low level DNA from individuals to inert surfaces.
TL;DR: It is demonstrated that there is a difference between individuals in their tendency to deposit DNA on an item when it is touched and that transfer of DNA from one individual to another and subsequently to an object is possible under specific laboratory conditions using the AMPFISTR SGM Plus multiplex.
Journal ArticleDOI
Trace DNA: a review, discussion of theory, and application of the transfer of trace quantities of DNA through skin contact.
TL;DR: With this minimal amount of contact required to yield a suspect profile comes tremendous crime solving potential, and a number of considerations for prudent application, and the maximization of evidentiary value.
Journal ArticleDOI
An improved method to recover saliva from human skin: the double swab technique.
TL;DR: The double swab technique showed the highest percentage recovery of saliva from human skin among the three methods studied, and is suggested as an improvement over the classical single wet cotton Swab technique.
Journal ArticleDOI
The tendency of individuals to transfer DNA to handled items.
TL;DR: It is found that it may be more complicated than previously reported to categorise a person as being either a ' good' or a 'bad' shedder and that if truly 'good' shedders exist they may be significantly rarer than some have estimated.
