In a rapidly changing world, the ability to prevent invasions by intercepting foreign organisms or by implementing quarantine measures is critical. Few studies however investigate the effectiveness of such measures in preventing new or ongoing invasions.
Next generation sequencing is set to revolutionise the way in which we approach many fields of genetics, including population genetics. Prof Ben Evans (visiting C·I·B fellow and Associate Professor at McMaster University, Canada) recently presented a hands-on workshop for those wishing to gain a basic understanding of reduced representation genome sequencing.
Birds are important role-players in the spreading of seeds from the invasive tree Rooikrans (Acacia cyclops). The birds are especially attracted to the bright red fleshy stalks that surround the seeds.
The rates at which invasive species invade new areas are increasing now more than ever. As more invasive species are introduced around the globe, many invaders co-exist in the same areas.
Invasive alien plants can change the amount of rainwater that reaches rivers and streams. Some researchers found that there is a large impact, with substantial increases in water uptake and reduced volumes of water in rivers, while others found little or no impact.
