Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Uso de radiação gama para aumentar a variabilidade genética em capim-jaraguá

Boletim de Indústria Animal, 2014
Mutações espontâneas ou induzidas podem gerar importante variabilidade genética, útil para muitos programas de melhoramento de plantas. Objetivando avaliar o efeito mutagênico da radiação gama em capim-jaraguá (Hyparrhenia rufa), sementes férteis foram irradiadas com 400 Gy pela exposição à fonte de 50Co. A geração M1 foi avaliada no campo.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

Conservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
