Despite 95% of the archipelago falling under the Galapagos National Park, invasive plants spreading from the inhabited areas are having large impacts on the native flora and fauna.
Anne Guezou, one of the botanists of CDF, says: "Thanks to the cooperation of residents we were able to visit every property in Puerto Villamil and obtain the first complete baseline of introduced species."
Five species were identified as potentially serious weeds that should be completely eradicated from the island, including the "lead tree" Leucaena leucacephela, regarded as one of the worst tropical weeds.
"By identifying invaders before they become widespread, and investing in their eradication or control we can protect this World Heritage site from their impacts." says Guezou. She adds, "Early detection must go hand in hand with preventing the arrival of more non-native plants into Galapagos".
Staff at the Charles Darwin Research Station are working with the Galapagos National Park and SESA (Ecuadorian Agricultural Health Service) to prevent importation of plants from mainland Ecuador.
This work was accomplished with the support of Project "Control of Invasive Species in the Galapagos Archipelago", a donation from the Global Environment Facility (GEF) to the Ecuadorian Government, represented by the Ministry of Environment.
The study is published on October 17 in the online, open-access journal PLoS ONE.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
