Poisons are silent, effective and cheap, making the especially dangerous in Africa where they are used for both pest control and illegal poaching.
However, as a new study in Annals of the New York Academy of Sciences reveals, they also kill un-intended wildlife.
In southern Africa colonial administrators sanctioned the poisoning of predators and scavengers, a practice which would continue far into the 20th century.
Dr. Darcy Ogada, from The Peregrine Fund, Nairobi, explores the impact of these campaigns and the proliferation of wildlife poisoning in the 1980's and 1990's as the commodification of Africa's natural resources continued to rise.
The study reviews legislation across the continent, but finds that legal loopholes and lax enforcement remain barriers to wildlife protection.
After reviewing a breakdown of species whose populations have been ravaged by poisoning, Dr Ogada calls for the establishment of regional pesticide centers across Africa that can identify pesticide hotspots and hold a mandate for chemical testing, education and public engagement.

Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their ability to process sounds in the world around them.
The researchers, who describe their experiments in the Dec. 3 edition of the journal Cell, show how hair cells in the inner ear can be activated in the absence...
Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
