What Lake Sturgeon genetics reveal about population structures
The freshwater fish Lake Sturgeon experienced drastic population declines across North America beginning approximately 150 years ago. Although commercial harvest has since ceased, many populations have been slow to recover. Stocking programs have been used to help recover the species, but they need to be approached cautiously as populations of fish that have been isolated for thousands of years may […]

Strength in difference: Genetic distance and heterosis in China
Cross-breeding between different species or populations can cause “hybrid vigour”, or heterosis, resulting in offspring who are genetically fitter than their parents. While this phenomenon is widely recognised in some plants and animals, it is poorly understood in humans. In recent work, Dr Chen Zhu of China Agricultural University, along with her colleagues Dr Xiaohui Zhang, Dr Qiran Zhao and […]
