The large-scale death of bees could culminate in an ecological and agricultural disaster. This may present as significantly reduced wild and domestic flora, as well as drastically reduced availability of various fruits, vegetables and nuts. There are several pressures on the global bee population, e.g., use of pesticides, destruction of habitat and infection with pathogen-carrying mites. Professor Ivan Toplak, an […]

River degradation is a widespread consequence of human development. In Seattle, Paul Bakke, founder of The Science of Rivers, along with a leading channel-design engineer and an aquatic ecologist, have implemented an innovative urban stream restoration project. A traditional stream restoration approach was transformed by adding an engineered streambed designed to restore and enhance the hyporheic zone. The project has […]

How natural disturbances sustain diversity

Natural disturbances like wildfires have a positive effect on species composition.

While natural disturbances like fires and floods can pose a risk to human life, in some places these events can help to support a diverse ecosystem. Forest fires, for example, allow species like oak to thrive and support a rich insect population, which in turn feeds many different birds. Dr Mike Eichholz of Southern Illinois University Carbondale studies the influence […]

Extinct giants, a new wolf and the key to understanding climate change

In this research article: Dr Meachen hopes to uncover the secrets of the mass extinction of the last ice age by re-opennig excavations at Natural Trap Cave (NTC) in North America

After its last excavation in the 1970s, a group of palaeontologists, genetics experts and cavers led by vertebrate palaeontologist and mammalian carnivore specialist Dr Julie Meachen of Des Moines University, have re-opened excavations at Natural Trap Cave (NTC) in North America. During this project, Dr Meachen hopes to uncover the secrets of the mass extinction of the last ice age […]
