DNA Barcoding Elucidates Cyprinid Reproductive Interactions in a Southwest Virginia Stream

Pneumococcal resistance in southwest Virginia.

Resistance patterns of Streptococcus pneumoniae in southwest Virginia were determined for 100 consecutive, hospital-based isolates, mostly from adults. Oxacillin disk screening identified all resistant isolates. Sixteen percent of the isolates were penicillin resistant (10% were highly resistant). E-strip testing revealed the following MICs (in micrograms per milliliter, with percentages of iso...

Flash flood awareness in southwest Virginia.

Flash floods are one of the most dangerous weather-related natural disasters in the world. These events develop less than six hours after a rainfall event and create hazardous situations for people and extensive damage to property. It is critical for flash flood conditions to be warned of in a timely manner to minimize impacts. There is currently a knowledge gap between flood experts and the ge...

Determining Plant – Leaf Miner – Parasitoid Interactions: A DNA Barcoding Approach

A major challenge in network ecology is to describe the full-range of species interactions in a community to create highly-resolved food-webs. We developed a molecular approach based on DNA full barcoding and mini-barcoding to describe difficult to observe plant-leaf miner-parasitoid interactions, consisting of animals commonly regarded as agricultural pests and their natural enemies. We tested...

DNA Barcoding: a new tool with wide array of applications

DNA barcoding is a new term introduced in to scientific literatures by Hebert and coworkers almost a decade ago. The concept of barcoding alone is well-known to the public: a series of black bars printed on many commercial products (Universal Product Code), which are used to distinguish different products. Advances made in molecular biology and molecular techniques late 20th century e.g. sequen...
