Conducting wildlife surveys has always presented a problem for biologists. Physically capturing live organisms can have a destructive environmental impact—not to mention smaller or elusive species are easy to miss. For such difficult species, eDNA changes everything. The technique relies on living things leaving traces as they move through a space:...
We all know the frustration of having no phone or internet signal when carrying out our daily lives, but in the Angola wilderness, the team has no standard connectivity for weeks at a time. Thankfully, BGAN satellite technology now offers a vital connection to the outside world. Standing for broadband global area network, these laptop-sized devices...
The method of collecting data on an expedition has evolved massively over the decades. From paper and pencil to specialist software to everything now being accessible in the palm of a scientist’s hand. Smartphones have changed the lives of scientists in the field because now they can easily capture data quickly and efficiently. During biodiversity ...
In the last 10 years, drones have decreased in size so that an expedition can now carry one along without having to worry about space or weight. Multirotor stabilization and automation mean drones can be thrown and caught from a canoe while moving along a river, and built-in, high-quality cameras let the team survey the area ahead. Drones are inval...
